2.3 Overall Principles of Operation

This section of the manual describes the principles of operation of the DINAMAP

™

Compact monitor. The section is arranged to give an overall description of the instrument, the following sections then detail each of the functional systems. For full assembly drawings, circuit diagrams and parts lists of the component circuit boards, refer to section 8 of this manual. The system block diagram of the DINAMAP

™

Compact monitor is shown in drawing 8600EB.

Patient vital signs can be measured by a variety of electronic sensors, including oscillatory pressure sensors for Non-Invasive Blood Pressure measurement. Both the DINAMAP

™

Compact T and TS models are provided with a predictive temperature parameter determination. The Compact TS model is also equipped with a Nellcor Puritan Bennett

™

Blood Oximetry module enabling oxygen saturation and heart rate to be determined from information received via a finger sensor.

Operator access is via buttons and the rotor located on the front panel. A liquid crystal graphics display module provides the user with menu, alarm and status information as well as a plethysmograph display or a record of previous measurements. Parameter information is presented by multiplexed seven segment LED displays and discrete LED indicators. A thermal printer provides hard copies of patients vital signs either automatically or on demand. A built-in speaker and piezo-electric sounder advise the user of pulse signals and alarm conditions.

The monitor is designed to operate from AC mains via the supplied power converter, or from an internal rechargeable battery. The external AC power converter rectifies the mains to produce a raw DC supply which is regulated internally to provide the DC operating power. The external raw DC source is employed to charge the internal batteries. The real time clock and user monitor settings are maintained by an internal rechargeable NiCd backup battery.

The monitor includes a pneumatics system required for NIBP operation. NIBP determinations are made by pumping up the air pressure in a restrictive cuff and monitoring the oscillatory signals in the system as the pressure is released. Large deflation steps are employed for NIBP and the system processor interpolates measurements between steps. The pneumatic system then regulates operation of the pneumatic pump and valves. An overpressure sensor provides independent protection against over-inflation. Protection against deflation failure is inherent in the design; the valve and pneumatic system being designed to auto-deflate the system in the event of power fail or alarm situations.

Blood Oximetry (SpO

2

) determinations (model TS only) are made using a proprietary module from Nellcor

Puritan Bennett

™

, which communicates the parameter measurements to the system processor via an internal serial port.

Predictive temperature measurements are based on a 3 or 12-minute mercury in glass reference. Predictive

Temperature probes can be connected to the monitor to provide an analog signal representing the measured temperature. An A/D converter then digitizes this analog signal; this information is then interpreted by the system processor and displayed for viewing.

2.4 Functional Description

The functions of the DINAMAP

™

Compact monitor can be separated into eleven discrete parts. The following paragraphs describe each of the Monitors, with full circuit diagrams provided in section 8.

2.4.1 System Processor

The system processor is based on 68302 microprocessor IC22 on the Main Board. A master 19.6608 MHz clock generated by XL1 exits the system processor at pin 98 and is divided by 16 inside binary ripple

19

counter IC36 to provide the 1.23 MHz ADC clock. Communication between microprocessor IC22 and all bus devices is provided by a 24-bit address bus, 8-bits data bus and the three wire serial peripheral interface

(SPI) bus. The system processor is equipped with a watchdog timer and reset circuit.

The system program is stored in a 4 Mbit FLASH memory IC28 as 512k by 8 bit words. Program memory is provided by a low power 1 Mbit SRAM IC32 formatted as 128k by 8 bit words. Non-volatile settings are stored in an EEPROM IC26 which talks to a dedicated serial port on the system processor. All bus devices are powered from the +5VD digital supply, except for the RAM that is also powered from the VRAM supply when the system is in “standby” mode.

Should the software detect a system fault or fail to reset its watchdog timer, the system processor will output a logic low level on its watchdog output WDOG. This is latched as FAILSAFE by the output of the bistable formed by IC31, allowing the output of the relaxation oscillator IC1 to pass through IC4 to sound the piezo sounder LS1. The FAILSAFE signal is also used to disable the isolated power supply module PM100.

The power supply board battery backup voltage BATT_BACKUP, derived from either NiCd battery or an external supply, appears on the supervisory circuit IC35. This supervisory circuit has two functions. First, it generates Reset and Halt signals for the system processor when the 5 volt power supply powers on and off respectively. Secondly, it controls transistor TR8, allowing the 5 volt line to power the RAM chip IC32 and

PIC when the system is “on”, or the BATT_BACKUP to power the RAM and the PIC when the system is

“off”. This allows values to be saved in the otherwise volatile RAM and to maintain the low power standby mode of the PIC.

Additional control signals from the system processor are decoded by IC16, which generates seven chip select lines and IC17 which generates latch outputs for the LED display drivers. The data bus D0 ~ D7 is filtered by inductors L12~19 to produce a buffered data bus DB0 ~ DB7 for the display drivers.

There is also a PIC micro-controller IC5 on the power supply board 8620AB, which has its own independent watchdog, reset circuit and provides the real-time clock function. The PIC provides control of PSU status, battery charging, printer and alarm/annunciator audio output. Communications between the system processor and the PIC are continually monitored in order to provide additional fail-safe security for the monitor. All measurement, alarm and communications ports of the instrument are isolated to IEC601.

2.4.2 Temperature System

The temperature system for the Model DINAMAP

™

Compact Monitor for reading predictive thermistor probes is located on the Main Board.

If a thermistor probe is used, the resistance of the probe varies in relation to temperature. The probe resistance is effectively in parallel with R63 and therefore a change in temperature results in a change in voltage applied to input selector IC19. The selected input voltage from IC19 is connected to the voltage to frequency converter (VFC) IC18. The frequency of the square wave output from the VFC varies proportionately to the input voltage. The output signal is isolated through opto-coupler PC2 and enters the system processor, as PRED_TEMP_F. The processor receives the square wave signal and determines the temperature by counting the number of edges received per unit interval.

Through the application of a software algorithm, the system processor provides two select lines TEMP_SEL0 and TEMP_SEL1. These are isolated by opto-isolators PC3 and PC4 and used to control the input selector

IC19, allowing the appropriate resistor tree to be selected. There are four selectable channels, two providing calibrations points, a third used for probe type detection and the fourth for the thermistor measurement.

The probe type is determined by measurement of the frequency produced by the VFC from a DC input derived from resistor tree R59-R61; for an oral probe this produces a frequency equivalent to 42 degrees

Celsius, Rectal probes short out R61 and hence change the frequency slightly. The software is capable of determining which probe type is attached and hence selects the appropriate measurement mode.

20

Compensation for drift in accuracy of the system is achieved by the unit recalibrating itself on switch on and after each measurement and at ten-minute intervals. Calibration is achieved by measuring two points on the high precision resistor chain of RV3, R70, and R74-77 which equate to 10°C and 37°C. Any changes in

VREFI or voltage to frequency transfer characteristic can therefore be accommodated within reason.

The temperature circuit is powered from an isolated 5-volt and

?

9 volt supply (5 and

?

15V on revision 04 and earlier), these supplies are generated by the isolated power supply module PM100. Calibration of the voltage and hence frequency in the temperature reference circuit is achieved by the use of resistor trees, attached to a stable reference voltage. This reference, VREFI is 3.24 volts (nominal) and is generated from the isolated 5-volt line by D2, adjustment provided by RV2. Thus RV2 will adjust the overall calibration of voltage ranges X0, X1 and X2. Additional adjustment of the calibration points X0 and X1 is provided by RV3 in their resistor tree. Together RV2 and RV3 are used to calibrate the temperature circuit.

The VREFI may be measured across TP3 and TP2, and the PRED_TEMP_F signal may be measured across TP9 and TP6.

2.4.3 NIBP System

The non-invasive blood pressure system measures blood pressure and pulse rate. The NIBP measurement circuitry is located on the Main Board.

To measure blood pressure, a reference voltage generated by IC2 supplies a bridge pressure transducer

ML1 to enable it to convert air pressure from the pneumatics system into an analog voltage. The instrumentation amplifier IC5 amplifies this voltage. The unfiltered signal PT1 is routed to into an eight channel analog multiplexer, IC20. When selected, the output signal is buffered by IC21 as signal

BUF_ANA_MUX and enters the ADC IC23. The digitized output of the ADC is presented to IC24, an octal buffer/line driver, from where it is transmitted to the data bus and the system processor. Pressure transducer offset PT1_REF from the output of IC2 also enters the analog multiplexer IC20. When selected, it provides an off-set value to the system processor. The processor then measures the offset value and subtracts the offset from PT1 measurements. The control signals for the multiplexer (ASEL0 ~ ASEL2) are generated by the system processor.

The pulse rate component (typically one percent) of the cuff pressure signal is filtered and separated from the PT1 pressure signal. The low pass filter formed around IC9a allows the low frequency pulse signal through whilst attenuating any higher frequency noise. The signal is then ac coupled by the high pass filter of C20 & R41 in order to strip off the small pulse rate signal from the cuff pressure signal. IC9b then amplifies the pulse signal before being applied to high pass filter IC12. The output from IC12 FPT1 is routed to the analog multiplexer IC20 for selection by the system processor. The system processor controls the analog switch IC7, it is used to clamp and apply offset signals into the filtered pressure measurement channel.

The system software includes an internal on-line self-test feature for the FPT channel at power-up and after each non-STAT mode determination.

2.4.4 Pneumatics System

The pneumatics system provides air pressure for the NIBP cuff, manifolding for control of cuff pressure, and an overpressure signal to the system processor and pneumatic control logic GAL if the pressure exceeds

300 mmHg in adult mode or 158 mmHg in neonate mode. The system is comprised of an air pump, pressure transducer, overpressure detection circuitry, power control circuit, and two solenoid-operated pneumatic valves. Air from the pump is routed through the dump valve to the cuff output manifold.

The pneumatics system provides control of the pump by commands received from the system processor.

The PUMP_ON signal from latch IC3 on the Main Board is passed to the pneumatic control logic GAL IC1 on the power supply board. The GAL produces a pump drive signal which turns on FET TR4b, TR13 and TR8, pulling down the ground return side of the pump motor through current sensing resistor R31. Both the

21

Deflate and Dump valve control signals are also generated by latch IC3 (Main Board) and passed to the GAL

IC1 (power supply board). Pump motor current is sensed in R31 and amplified by IC4. This is routed to the system processor as PUMPC and also compared to a reference to produce an over current input signal to the GAL. If pin 9 of GAL IC1 goes high, pin 12 (signal LATCHED_OVC) will be latched high and the pump enable output will go high switching off the pump. The latched over current condition can be reset by the

Main Board processor asserting PNEURESET high.

The Deflate valve vents the system to atmosphere in its energized state. When the pump is operating, the deflate valve is de-energized by the GAL IC1 turning off FET TR1b in the ground return side of the valve circuit. If a failsafe, overpressure or deflate condition signal arrives on the GAL, the valve will be energized and the system will rapidly deflate. The over-pressure signal is produced by the pump pressure transducer and associated electronics, while the failsafe can be derived from the system processor’s watchdog output as well as from the PIC IC5.

Conversely, the Dump valve vents the system to atmosphere in its de-energized state. When the pump is operating during a determination cycle, the Dump valve remains energized, the GAL receiving a high level

DUMP signal from the latch IC3 on the Main Board. When the determination cycle is complete, or if an alarm condition arises, the DUMP signal from latch IC3 will go low causing the GAL to turn off FET TR4a and deenergize the dump valve, opening the system to atmosphere.

Because the action of deflation can be initiated by energizing one valve or de-energizing another, a power failure during a determination will always result in de-pressurization of the system.

The action of operating the Dump and Deflate valves produces a voltage across R20/21 and R66. This signal is labeled VALVESENSE and is routed to the multiplexer IC20 on the Main Board from where it can be selected by the system processor. The four possible conditions of the Dump and Deflate valves can be ascertained from the VALVESENSE signal.

Once the system processor has determined which cuff type is being used, it instructs latch IC3 to output an

ADULT signal to TR1. In the pump pressure transducer circuit on the Main Board, IC8 generates a high precision 5 volt reference, which is made available to dual op-amps IC10 and IC21. This reference is monitored by the system processor as PT2_REF. The buffered reference from IC21 is applied to excite the pump output pressure transducer ML2 on the Main Board (Transducer mounted on Pump assembly on revision 04 and earlier). The output of the transducer varies in proportion to the air pressure in the system.

The transducer ML2 output pins connect to IC11, an instrumentation op-amp in differential mode configuration. An offset voltage derived from the voltage reference IC8 is buffered by IC10b and fed to IC11 it is then summed with the amplified difference signal from the transducer. IC11’s output is passed to the analog multiplexer IC20 as PT2 and the inverting input of comparator IC15a where it is compared to the over pressure limit.

Note: For revision 04 units and earlier the reference to IC25 on the Main Board in the following paragraphs relates to IC10.

The system processor produces control signals POT_INC, POT_U/D and POT_CS to drive a digital potentiometer IC13 which sets the gain of amplifier IC25a and hence the over pressure limit. The “high” end of the digital pot is connected to the output of the output of IC25a while the “low” end of the pot connects to the precision resistor chain formed by R47, 48, & 50. The “wiper” of the pot connects to the inverting input of

IC25a. During factory set-up, the over pressure alignment is trimmed by selecting IC13 and incrementing its output up or down. After alignment is complete, jumper LK1 is removed, thus preventing chip select of the digital pot.

The output of IC25b applies an offset to the Adult/Neonate threshold input of IC15a. The output of IC15a, labeled UNFIL_OVP, is normally at a high logic level but changes to low when overpressure occurs. This signal is available as an input to the PSU board as unfiltered overpressure (UNFIL_OVP). UNFIL_OVP is then filtered by R49 and C27 and fed in to comparator IC15b to produce filtered overpressure signal

FLT_OVP and is made available to the PSU board. The overpressure threshold voltage reference is

22

buffered by IC12 to produce TH_VREF which can be measured by the system processor via multiplexer

IC20 and ADC IC23.

Upon clearance of the overpressure condition the Main Board system processor can reset the overpressure latch in GAL IC1 on the PSU Board, by asserting PNEU_RESET signal high, in order that another determination can be carried out.

2.4.5 SpO

2

System (TS & S models only)

Blood oxygen saturation and pulse determinations can be made (DINAMAP

™ using a Nellcor Puritan Bennett

™

finger sensor. This connects to the SpO

2

Compact TS and S only)

module fitted inside a shielded case mounted in the monitor. This module is supplied as a complete replaceable part, no service being possible.

The SpO

2

module communicates with the system processor via an isolated two wire serial interface. Data signals from the system processor (SPO2_TX) are isolated by opto-coupler PC6. From here they enter connector PL13 to the SpO

2

module. Likewise, data transmitted from the SpO

2

module are isolated by optocoupler PC5, from where it is routed to the system processor as signal SPO2_RXD.

The SpO

2

module (and the temperature determination circuit) is powered via an isolated power supply module PM100. This is powered from the +12VV supply and generates the isolated +5VI, +9VI and -9VI supplies (+5VI, +15VI and -15VI supplies on revision 04 units and earlier). On revision 06 units the isolated power supply module is switched on by the system processor SPO2_PSU_ON signal, turning TR11 off and setting the control input to ML3 high. On revision 04 and earlier units the isolated power supply module ML3 is turned on by grounding its -ve supply connection through FET TR12. In the event of a FAILSAFE condition arising, the control signal of ML3 is set low by TR10 switching on (06 unit), or by switching TR12 off (on revision 04 units and earlier).

2.4.6 Power Supply

The power supplies are generated and controlled on the power supply board.

The power supply is designed to operate from both an external DC line source and from a 12-volt rechargeable lead-acid battery. The supplied mains power converter provides 24 volt DC output. When both supplies are present, the power supply will operate from the line supply if it is greater than 12 volts. If the line supply is greater than 16 volts the battery will be charged both when the monitor is switched on and off.

The power supply sequencing functions are controlled by the PIC IC5.

Incoming line power from the external power converter has any high voltage spikes snubbed by transient suppresser D4 and over-voltage protection is provided by D6, R10 and CSR1. Should the line input voltage rise above 34 volts, zener diode D6 conducts, turning on thyristor CSR1. This causes a short circuit which blows the external DC line fuse. Reverse polarity protection for the power supply is provided by blocking diodes D8 and D29. A sample of the line input voltage is taken by R3 and R6 (DC_INPUT), and routed to the external DC detection circuit IC16 and the PIC.

The switcher IC3, inductor L1 and diode D10 form a flyback converter with a nominal output of 15.1 volts and VRAW of 14.8 volts through the battery blocking diode D11. A sample of the smoothed output is taken by R29 & R30 to provide a feedback voltage.

The PIC uses the DC_BATTERY, DC_INPUT and EXT_DC_ON signals to determine the available power sources. If valid power supply conditions exist and a battery is detected, the PIC will turn on TR7, which turns on p-channel FET TR6, allowing the +15VI line to charge the battery via D9, R17 and FS1. When charging is taking place, a voltage will appear across R17, which will be proportional to the charge current.

This voltage is sampled by R14 & R15 to produce the BATTERY_C signal.

23

If there is no valid external DC line supply applied to the monitor, the monitor will default to use the battery.

DC from the rechargeable battery arrives on thermal fuse FS1, from where it is routed to the source of TR2, a p-channel FET under the control of TR3. The battery supplies power to VRAW via transistor TR2 and diode D28. When operating from a battery, VRAW will be in the range 10.4 - 13.5 V depending on the battery charge. A sample of the battery’s terminal voltage is taken by R1 & R2 and applied to the ADC input of the PIC (DC_BATTERY). From this, the PIC can determine the charge state of the battery.

Diodes D24 and D25 provide a power supply line VDC_OP which is present whenever a supply is available.

This supply is used exclusively for IC16, a programmable voltage regulator with internal comparator. IC16 performs two functions. First, its internal comparator compares the sampled line input voltage DC_INPUT to an internal reference level. When the DC_INPUT is below approximately 10.4 volts, IC16 turns off TR14 to indicate to the PIC that there is no valid external DC input. The second function of IC16 is to generate a precision voltage supply from VDC_OP, set by R5 & R9 to 4.5 volts. This voltage is connected to the

BATT_BACKUP line by D13, D23 preventing the voltage from entering the NiCd backup battery. This battery, B1, has a nominal terminal voltage of 3.6 volts and is trickle charged form the +15.1 volt supply when the system is powered.

The VRAW supply, which is nominally 14.8 volts when operating from an external line voltage or 10.4 to

13.6 volts when operating from battery, is used to generate the other power supply lines. The monitor’s power on switch is routed directly to the PIC, which controls the set up sequencing of the power rails. The

PIC switches on the +5VD line then the +VDISP line, the 12-volt supplies are controlled by the system processor which turns them on after the +5VD supply is stable.

VRAW enters IC7, a step down DC-to-DC converter, which is used to produce the +5VD digital line. The 5 volt logic supply IC7 is controlled by the PSU_INH signal from the PIC. VRAW also connects to IC17 to produce the +4.5 volt LED display supply +VDISP, which is controlled by the PIC signal ENABLE_VDISP.

The 12 volt line and other supplies are controlled by the 12V_ON signal from the system processor on the

Main Board. When this pin is at a high logic level, TR9 is turned on, as is p-channel FET TR10. This causes the VRAW supply to enter IC8, a boost-switching regulator. R41 & R42 set the output voltage of the flyback converter to 14.5 volts, which is further regulated by linear regulator IC9 to produce the pump and valve supply +12VV line and linear regulator IC18 to produce the analog supply +12VR line. The output of TR10 also feeds the inverting switching regulator IC10, which produces a -14 volt supply to linear regulator IC19 that in turn produces the analog supply -12VR line. A sample of the +12VV line is taken by R44 & R45, producing the PUMP_V signal, while a sample is taken across +12VR and -12VR lines by R47 & R48 producing the ANALOG_V signal. These are measured by ADCs inside the PIC to confirm the operation of the power supplies.

2.4.7 Audio Amplifier

User warning sounds are generated by the power supply board PIC as a pulse width modulated digital signal AUDIO_FREQ. This signal is fed to all the inputs of the quad bilateral switch IC14, their outputs being connected together via a resistor ladder to produce a switched gain-summing amplifier IC6. The gain elements are operated by the PIC signal A_GAIN0-3, together providing a 4-bit (16 level) volume control.

The output of the summing amplifier IC6 also applies band-pass filtering to the audio signal. The circuit around IC6b sets the upper breakpoint of the filter, while the circuit on the input to the final amplifier IC15 sets the lower breakpoint and provides amplification for the speaker.

2.4.8 Alarm and Communication Interfaces

The remote alarm signal originates from the system processor on the Main Board, from where it is logic

ORed with the FAILSAFE signal, inverted and sent as the REMOTE_ALARM signal to the power supply board. The signal controls n-channel FET TR11 to drive the coil of the relay RL1/2. The switch side of the relay contains both normally open and normally closed contacts, which are separated from the monitor electronics via an isolation barrier. A dual pole dual throw relay is used, but its switch elements are connected in parallel to provide a single pole dual throw action with increased current capacity.

24

Communications signals use the RS232 bi-directional serial format. Digital TTL level signals from the system processor are converted to RS232 level signals on the power supply board by IC13, which generates the necessary positive and negative voltage swings. In addition, inverted TTL data transmit and receive lines are provided. A 5-volt supply is also made available to the serial port, this being protected by a

0.1 amp thermal resetable fuse.

2.4.9 User Controls

The user controls are comprised of four push buttons; power, stat, NIBP start/stop and alarm silence, and the rotor control. When the rotor control is turned, it operates an optical encoder producing a Gray code output. Pressing the rotor operates a push button switch. These rotor control signals and the four push buttons are encoded together on the switch board by a register latch IC2. The register is periodically polled by the system processor to determine if any of the switches have been operated. IC2 is controlled by the chip select signal KEY_CS and the read signal LD_RD. KEY_CS is produced by the Main Board chip select decoder IC16 under control of the system processor, while LD_RD comes from the processor.

The ambient light detection circuit comprises of the light dependant resistor LDR1 and a bias resistor in a potential divider configuration. A change in the level of incident light on the LDR1 causes its resistance to alters, changing the voltage applied to the PIC ADC which determines the ambient light level. The system processor regularly requests the ambient light level measurements from the PIC, and in turn controls the brightness of the LED displays on the display board.

2.4.10 Displays

All displays, except for line power indicator, are multiplexed, and are split into three separate control circuits, each with its own display driver. The power / charging green LED is controlled by the PIC software.

The three LED display drivers (IC1, 2 & 3 on the display board) are Maxim MAX7219’s, which are controlled by the system processor via the SPI bus. The LED parameter displays are divided into functional groups on the display board. IC1 drives the systolic and diastolic displays; IC2, the Temperature and MAP displays;

IC3, the Heart Rate and SpO

2

displays as well as the battery, °C, °F and Heart Rate discrete indicators. A current limiting resistor attached to iSET input of each driver IC sets the maximum segment current in the display; each current limiting resistor is different because each driver IC controls different sized LEDs. IC3 drives red and amber seven segment displays as well as red and amber discrete displays, additional low value resistors or links R1 to R11 are inserted in series with the anode of each diode to provide different

LED currents within the same multiplex group.

The display drivers are all controlled by the system processor via the SPI bus data signal SPTXD. This transmits the display data and controls the brightness of the displays by varying the multiplexer’s PWM ratio. Data is latched into each driver ICs when the respective load signal LED_LOAD0-2 is pulled high by decoder IC17 on the Main Board. This is synchronized with the LED SPI clock signal LED_CLK from the system processor.

Text and graphical data is displayed on the LCD graphics module, which contains its own on-board driver electronics. The module is controlled by the system processor via filtered data bus DB0 ~ DB7, address signal A4, RESET and the LCD_CS, LD_WE and LD_RD lines. The LCD_CS line is produced by the Main

Board chip select decoder IC16, while the LD_WE and LD_RD lines are derived from the system processor’s R/W and CS and logic ICs IC1 & IC27.

Backlight illumination of the LCD is provided, the green LED source being under software control via the system processor. The BACKLIGHT signal is decoded on the Main Board and used to turn on an N-channel

FET TR1 on the display board. A resistor sets the current and hence the constant backlight brightness.

The LCD module requires the +5VD and -VLCD supplies to function. The -VLCD supply is derived from the

-12VR supply and can be trimmed by potentiometer RV1 on the switchboard. This adjusts the effective

25

viewing angle or contrast of the LCD display. The trimmed voltage is nominally set to -9.6V and may be measured across TP1 and TP2 of the switchboard.

2.4.11 Printer

The monitor employs an Axiohm HPT4050 thermal printer module, fitted to the printer board, which contains the interface electronics. The PIC provides stepper motor control signals M_OE, M_PHASE1 and

M_PHASE2 to IC3 on the printer board. This converts these to sequential drive signals MP1_1, MP1_2,

MP2_1 and MP2_2 for the stepper motor.

The PIC also sends a PRINTER_TRIGGER signal to initiate printer action; this triggers a timer IC4 which generates the printer enable signal PRINTER_OE. To optimize print speed, print quality and the life of the print head, a thermistor constantly measures the temperature of the head. As the system heats up, the print head thermistor is used by the timer circuit to reduce the width of the PRINTER_OE pulse. The print head voltage +VP is also employed to alter the width of the PRINTER_OE pulse. A typical print trigger pulse width is 6 ms. An opto-transistor detects the presence of printer paper and a micro switch detects the status of the printer door, open or closed. These two devices are combined to produce the PRINTER_READY signal, which inhibits the printer action when clear and is sent back to the PIC as PRINTER_BUSY. Data for printing is sent from the system processor to the printer board via the SPI bus.

Because the instantaneous power demand of the printer is quite high, a dedicated 6.1-volt supply +VP is generated from VRAW by IC1 and extra reservoir capacity is provided by C16 and C17.

The first covers general maintenance functions, which can be performed without disassembly of the monitor.

? ?

The second covers use of the built-in Service Software.

? ?

The third describes how to calibrate the NIBP and overpressure detection of the monitor, or check their calibration.

? ?

The fourth describes maintenance, which requires removal of the monitor’s covers, disassembly of the components and internal alignments.

Procedures that pertain to SpO

2

, the printer and temperature components apply only to suitably equipped

DINAMAP

™

Compact Vital Signs Monitors.

3.1 General Maintenance

3.1.1 Replacing Fuses

The Monitor contains three fuses:

? ?

Replaceable fuse protecting the external line input

? ?

Thermal auto resetting fuse protecting the battery input

? ?

Thermal auto resetting fuse protecting the 5V output on the Host Communications Port

UK models will also be protected by a fuse fitted in the mains plug of the power converter input cable.

To replace the External Line Fuse, first remove the line power cord from the rear of the Monitor, if connected. Insert a flat bladed screwdriver or small coin into the slot in the fuse holder cap and carefully rotate anti-clockwise several revolutions. The fuse-holder cap and fuse will be released.

Pull the fuse from the cap and inspect it for a burned or broken filament. If the filament appears to be intact, check the fuse for continuity with an ohmmeter. If damaged, replace with a fuse of the specified rating and type.

To reassemble, push the fuse into the cap and insert both into the holder. With the flat bladed screwdriver or small coin, rotate the cap clockwise until it is flush with the holder. Do not over tighten. Apply the external line power and confirm that the monitor operates correctly.

3.1.2 Periodic Maintenance

Periodic maintenance tasks include cleaning the Monitor, checking pressure calibration, checking for pneumatic leaks, checking the overpressure cut-out, and checking the temperature calibration where fitted.

Cleaning the Monitor

The exterior of the Monitor may be wiped clean with a cloth slightly dampened with mild detergents or normal hospital bactericides.

? ?

Do not immerse unit.

? ?

Do not clean with isopropyl alcohol or other solvents.

27

? ?

The adult DURA-CUF

™

range supplied for use with this Monitor may be cleaned by hand washing in warm soapy water. Care should be exercised, however, to ensure that no water enters the cuff or cuff hoses at any time. In the event water accidentally enters the cuff, passing air through the cuff will dry it.

? ?

The neonatal cuffs are supplied for single use and should be discarded if they become soiled.

? ?

Do not immerse hoses.

? ?

Do not immerse cuffs without prior application of cuff hose caps.

CAUTION

? ?

Moisture or foreign substances introduced into the pneumatic system can cause damage to the unit. Calibration equipment should always be kept dry and free of particulate matter.

? ?

The probe holder may be removed and cleaned with a mild detergent. The probe holder may be immersed during cleaning.

? ?

Do not immerse temperature calibration plug.

? ?

The probe may be cleaned with an alcohol solution. Use a cloth or sponge, just damp, not wet, and avoid getting any liquid into the interior of the probe.

Checking of Calibrations

Refer to section 3.3 for instruction on the procedures required to check each of the parameter calibrations.

3.1.3 Care of the Storage Battery

It is best to keep the battery charged as fully as is practical and never store the monitor with the battery in a discharged condition. When the battery will no longer hold a charge, remove and replace with one of the same part number.

To charge the battery, connect the supplied power converter to the monitor's rear panel, then plug the converter’s mains lead into an appropriate AC receptacle. The battery will charge regardless of the position of any other monitor switches.

A battery that is completely discharged can be fully recharged by the monitor within eight hours. Charging will take place with the monitor switched on or off, as long as it remains connected to an external AC power source via the supplied power converter.

The expected lifetime of the battery largely depends on the way in which the instrument is used. If the battery is allowed to completely discharge before being fully recharged, the battery should survive around two hundred recharge cycles. If the battery is used in such a way that it never becomes more than one third discharged and is fully recharged whenever possible, it can survive up to twelve hundred cycles. This means that by thoughtful usage, the lifetime of the battery can be extended up to six times.

PRECAUTIONS

? ?

To ensure that the battery will be ready for portable operation, keep the unit connected to a mains supply whenever possible.

? ?

Repeated failure to fully charge the battery will result in a significant reduction in battery life.

Avoid storing batteries at temperatures above 77° F (25° C). High storage temperatures can dramatically increase the rate of self-discharge of the battery.

28

Most alignment and repair operations can only be performed with the monitor disassembled. This section describes how to remove the covers, disassemble the chassis and remove the circuit boards. The

™ description refers to fully equipped DINAMAP Compact TS models. DINAMAP

™

Compact T models do not have SpO

2

functions and therefore the SpO

2

related components are not fitted.

Before beginning disassembly, disconnect the line power cord from the power socket and remove the rechargeable lead-acid battery. Be careful to observe anti-static handling precautions throughout.

Note: Pictures shown are from a revision 06 unit, appearance may differ slightly on earlier units.

3.4.1 Removal of the Front Panel

The front panel contains the Display board, Liquid Crystal Display module and switchboard. The Rotor,

Temperature probe socket and SpO

2

socket (model TS) are also mounted on the inside of the panel.

The front panel must be removed if access to any of the boards or modules mounted on it or behind it is required. To remove the panel, release the two Pozidriv

™

screws mounted inside the hand recess of the instrument’s rear enclosure.

Front panel retaining screws

Then carefully pull the top of the front panel away from the rear enclosure. The panel will tilt forwards but is still retained by two plastic clips at its bottom edge. Unhook the front panel from these clips, taking care not to damage them. This is particularly important when refitting the front panel later.

42

Before the panel can be separated from the case, it is necessary to disconnect the switchboard cable, temperature probe cable and SpO

2

sensor cable if fitted.

The switchboard ribbon cable plugs into socket PL10 on the Main Board via a ferrite, which clamps the cable to the front of the chassis metalwork. Detach the ferrite from the chassis front plate by separating the

Dual-Lock

™

fastener.

With the ferrite detached, the ribbon cable can be unplugged from socket PL10.

43

The cable from the Temperature probe socket plugs into connector PL14 on the Main Board and is easily removed.

The SpO

2

cable runs from the small front panel connector printed circuit board to another small PCB with integral connector attached to the Nellcor Puritan Bennett

™

module. To remove the PCB from the front panel, locate and remove the two small Pozidriv

™

retaining screws, which fix the PCB metal support bracket to the front panel. The cable and PCB assembly can then be lifted away.

3.4.4 Removal of the Main Board and Power Supply board from the chassis

To remove the Main and Power Supply boards from the chassis, the valve control and pump connector must first be removed. This is visible through the hole in the rear of the chassis.

The chassis spade terminal must also be removed. This is located between the top of the chassis and the

Power Supply board (Unit revision 06 only).

Disconnect pneumatic hose from pump assembly to Main Board secondary pressure transducer on revision

06 units. (Disconnect pressure sensor cable on earlier revisions)

The boards can now be slid together up and out of the pcb guides built into the metalwork of the chassis.

47

To separate the boards, use a fine nosed pliers to pinch the tip of the nylon pcb spacer while gently pulling the boards apart. Note that this will result in the loss of the user settings.

To avoid damage to the PCB interconnection, ensure that the boards are not tilted or twisted relative to each other as they are separated.

3.4.5 Removal of the Pump and Pressure Transducer

To remove the Pump assembly, take out the two Pozidriv

™

screws holding the metal pump retaining strap.

3.4.7 Reassembling the Monitor

Re-assembly is a direct reversal of disassembly, however additional care must be taken to ensure that all cables and hoses are refitted correctly. The main points to note when reassembling are:

? ?

Pay particular attention to the wire dressing and ensure that all ferrite components are refitted correctly.

? ?

When reassembling the chassis, remember to reconnect the valve control from the pump to the power supply board.

? ?

When refitting the front panel, ensure that the copper earthing fingers of the front-panel engage correctly inside the rear enclosure.

? ?

Ensure that the hoses to the front panel are not trapped or kinked while refitting the panel.

? ?

Keep your work area clean. It is quite easy for the plastic display panel cover to become scratched if the front panel is pressed against a hard object such as a screw.

? ?

Be sure to re-calibrate and test the monitor as per section 3.4.1 and 3.4.6 before releasing it for clinical use.

When an NIBP measurement is attempted unit alarms with the following message on LCD.

‘N44-NIBP: Timeout’

Total Time’ or

‘N55-NIBP: Timeout

Pressure’ or

‘N99- No determination’

Possible Causes

State of pneumatic system does not concur with the unit’s expected software state. e.g. pressure in system exceeds ambient level despite system being set open to atmosphere.

If a failure condition arises in the valve control circuitry that does not allow the cuff to deflate an

N12 error will be reported.

If pump runs continuously on power up or remains on at any time when it is supposed to be off a N13 fault condition will be set.

Leak in pneumatic system.

Further Checks

Determine status of valve drive and hence locate any valve drive problem.

Most likely to be a fault on the

Pneumatics Control Gal IC1 or

TR1 or TR4 on the PSU board.

Therefore swap or test PSU

Board.

Fault could also be caused by

Main Board Failure with IC3 being the most likely cause.

Most likely to be a fault on the

Pneumatics Control Gal IC1 on the PSU board. Therefore swap or test PSU Board.

Fault could also be caused by

Main Board Failure with IC3 being the most likely cause.

Fault could also be due to defective pump current measurement circuitry on PSU

Board.

Test unit with known good cuff.

If unit is leaking check integrity of internal hoses if ok swap or test pump assembly.

N44 and N55 warnings may be caused by excessive movement of patient (‘Motion Artifact’).

Main Board NIBP circuitry fault or

PSU Board pneumatic control fault or Pneumatic Assembly fault

Ensure ‘Motion Artifacts’ are not the cause of the failure.

Carryout an NIBP calibration check this may indicate if their is a problem with either pressure measurement channels PT1

(shown on systolic display) or

PT2 (shown on diastolic display).

If calibration is satisfactory fault may be due to a pneumatic problem with cuff deflation.

The fault may also reside on the

NIBP pulse determination circuitry on the Main Board.

Spec.’

(Filtered Voltage),(Code

Line Failure), 0,0

Unit alarms with the following message on

LCD:-

‘PIC: Incompatible SW

Version

0, (code line failure),0,0

Possible Causes

The PSU Board PIC software has detected that the +12VR or -

12VR rails are operating out of spec.

The software has detected an incorrect PIC software version to run with Main Board software.

Further Checks

Check and isolate faulty supply.

Fault is most likely to be on the

PSU Board or the Main Board.

Fault could also be caused by input voltage to IC18 or IC19 on

PSU board going to low and therefore causing the regulators to dropout. This could be caused by excessive current drawn on the +12VV supply or interruptions to the input supply caused by erroneous operation of supply switch TR10.

Check Main Board and PSU
