Service Manual Safety Summary

Blood Pressure Cautions

These cautions pertain to the Spot LXi blood pressure feature.

Caution Minimize extremity and cuff motion during blood pressure readings.

Caution If the blood pressure cuff is not at heart level, note the difference in reading due to the hydrostatic effect. Add the value of 1.80 mmHg (.2 kPa) to the displayed reading for every inch (2.5 cm) above heart level. Subtract the value of

1.80 mmHg (.2 kPa) from the displayed reading for every inch (2.5 cm) below heart level.

Caution Proper blood pressure cuff size and placement is essential to the accuracy of the blood pressure determination. See Reusable Two-Piece Cuff

Measurements or Durable One-Piece Cuff Measurements of the Directions for

Use for sizing information.

Caution The position and physiologic condition of the subject can affect a blood pressure reading.

Temperature Cautions

These cautions pertain to the Spot LXi temperature feature.

Caution The SureTemp Plus feature only operates with the probe well in place.

Caution Do not use alkaline batteries in the Braun ThermoScan PRO 4000.

Caution Biting the probe tip may result in damage to the probe.

SpO

Cautions

These cautions pertain to the Spot LXi SpO

feature.

Caution The pulse oximeter is calibrated to determine the percentage of arterial oxygen saturation of functional hemoglobin. Significant levels of dysfunctional hemoglobin such as carboxyhemoglobin or methemoglobin may affect the accuracy of the measurement.

Caution Some sensors may not be appropriate for a particular patient. If at least 10 seconds of perfusion pulses cannot be observed for a given sensor, change sensor location or sensor type for perfusion to resume.

Caution Physiological conditions, medical procedures, or external agents that may interfere with the pulse oximeter’s ability to detect and display measurements include dysfunctional hemoglobin, arterial dyes, low perfusion, dark pigment, and externally applied coloring agents such as nail polish, dye, or pigmented cream.

Caution When selecting a sensor, consider the patient’s weight and activity level, the adequacy of perfusion, the available sensor sites, the need for sterility, and the anticipated duration of monitoring.

Safety Summary

Electrostatic Discharge (ESD)

Welch Allyn Spot Vital Signs LXi

Electrostatic discharge is a sudden current flowing from a charged object to another object or to ground. Electrostatic charges can accomulate on common items such as foam drinking cups, cellophane tape, synthetic clothing, untreated foam packaging material, and untreated plastic bags and work folders, to name only a few.

Electronic components and assemblies, if not properly protected against ESD, can be permanently damaged or destroyed when near or in contact with electrostatically charged objects. When you handle components or assemblies that are not in protective bags and you are not sure whether they are static-sensitive, assum that they are static-sensitive and handle them accordingly.

• Perform all service procedures in a static-protected environment. Always use techniques and equipment designed to protect personnel and equipment from electrostatic discharge.

• Remove static-sensitive components and assemblies from their static-shielding bags only at static-safe workstations - a properly grounded table and grounded floor mat - and only when you are wearing a grounded wrist strap (with a resistor of at least 1 megohm in series) or other grounding device.

• Use only grounded tools when inserting, adjusting, or removing static-sensitive components and assemblies.

• Remove or insert static-sensitive components and assemblies only with monitor power turned off.

• Insert and seal static-sensitive components and assemblies into their original staticshielding bags before removing them from static-protected areas.

Always test your ground strap, bench mat, conductive work surface, and ground cord before removing components and assemblies fromtheir protective bags and before beginning any disassembly or assembly procedures.

Functional Testing Procedures

Perform the functional testing procedures in this section before returning Spot LXi into service.

Verify you are using a calibrated pressure meter with an accuracy of better than ±3 mmHg and that the calibration certificate is traceable to NIST.

Subtract the rated accuracy of the pressure measurement standard from the ±3 mmHg rated accuracy of Spot LXi. This is the pass/fail criteria to determine if the device is within calibration. If the differences between Spot LXi and the pressure measurement standard are within the pass/fail criteria at all specified pressures then the device is within calibration.

Follow the steps in “Connections” on page 34.

Enter the “Internal Configuration Mode” on page 24. Use the Navigation and Select buttons to select Blood Pressure > BP Calibration Check.

Connect to the 500 cc cylinder.

Select Test > Calibration in the repair software. The dialog box displays the device manometer reading, battery reading, and valve and pump status.

Use the Navigation and Select buttons to select Blood Pressure > BP Calibration

Check.

Verify the valve on Spot LXi is closed (the menu choice shows “Open Valve”).

Use the hand bulb to verify Spot LXi is within calibration specification at the target pressures of 250±5 mmHg, 150 ±5 mmHg, 50 ±5 mmHg, and 0 mmHg with each reading within ±3 mmHg of the target pressure except for the 0 mmHg reading which is within ±1.0 mmHg.

Set the power supply to 5.6 Vdc (+0.3/-0.0 Vdc). Verify the voltage reading meets the specification (see “Voltage Calibration” on page 82).

After completing this test, return the power suppy to 6.5 Vdc (+0/-0.25 Vdc).

Technical Overview

System Description

The Spot Vital Signs LXi automatically measures systolic and diastolic pressure (excluding neonates), pulse rate, temperature (oral, adult axillary, pediatric axillary, rectal, and ear), and pulse oximetry (SpO

) as well as calculates Mean Arterial Pressure (MAP).

Furthermore, Spot Vital Signs LXi allows the entry of height, weight, respiration rate, and pain level. Spot Vital Signs LXi also calculates Body Mass Index (BMI) following height and weight entry.

The device is intended to be used by clinicians and medically qualified personnel. It is available for sale only upon the order of a physician or licensed health care provider.

Refer to the Spot Vital Signs LXi Directions for Use manual for complete information.

Battery System

Spot LXi includes a 6 Volt, 6 amp-hour sealed lead-acid battery that supplies all power to the device. An external power supply charges the battery. The battery is always on-line

(floated) rather than switching out when attached to the external power supply.

Spot LXi uses a fuse and a shunt diode for protection against reverse battery connections.

The fuse is located on the main board in the negative battery line and a reverse battery connection causes it to blow and require repair. The negative line location is more likely to short the battery (+) wire to ground than short the battery (-) wire to the VBUS node.

Battery Charger

Provides two levels of power to fast-charge or to float the battery at fixed voltages using software control. The fast-charge level rapidly brings the battery up to near-full capacity (7

Volts) using software to not overcharge the battery. The float level, set per the manufacturer’s recommendation, slowly tops-off the battery and can stay on indefinitely.

“CPU I/O” Power Supply

Provides power to the I/O pins of the DragonBall MPU and the attached peripheral IC’s.

The nominal voltage is set to a value of 3.15 Volts so that both the 3.0 Volt MPU and 3.3

Volts peripherals can operate within specifications. Spot LXi uses buck switching topology for efficiency and an on-off power latch directly controls the power supply.

CPU Core Power Supply

Powers the MPU core only and operates at the recommended Dragonball voltage range of 1.8 +/- 0.1 Volts; 2.0 Volts absolute max.

Technical Overview Welch Allyn Spot Vital Signs LXi

The +3.15 Volt supply powers the +1.8 Volt supply for efficiency and, more importantly, for power sequencing. During power-on the +1.8 Volt supply cannot exceed the +3.15 Volt supply. The R207/C182 further delays the +1.8 Volt supply. During power-off, D106 prevents the +1.8 Volt supply from exceeding the +3.15 Volt supply by more than a partial diode drop.

+5V Supply

Provides supply to miscellaneous loads that require more than 3.15 Volts. The Power

Latch controls the supply and the average load current is small, so efficiency is not important.

Clock/Calendar Power

The Clock/Calendar U19 receives power from two sources. During power on the clock runs from the +5 Volt supply and during power down the clock receives power directly from the battery potential using a voltage divider. Capacitor C131 provides power to the

U19 during the battery exchanges. Zener D102 prevents overvoltage to U19 in the case of operation directly from the charger.

Mod F NIBP Power

This module is powered directly from VBUS through an EMI filter. Software via BP-PWR-

ON-BAR controls the power. Level shifter Q115 / Q104 assures that the module remains off when the MPU is unpowered.

SpO

and Thermometer Power

A common structure supplies SpO

and thermometry. A single push-pull driver delivers squarewave power to a pair of isolation transformers, one for SpO

and the other for thermometry. THERM-PWR-BAR activates the driver under software control. Level shifter Q118, Q119 assures that the module remains off when the MPU is unpowered.

In the push-pull (forward) configuration, VBUS is multiplied by the transformer turns ratio and supplied to the input of the rectifier diodes. This is filtered and passed through lownoise 5-Volt linear regulators to supply power to the parameter modules.

LCD Power

The LCD data interface connects directly to the +3.15 Volt MPU I/O power supply. This powers the driver ICs inside the LCD pane and assures the data interface to the LCD is always powered when the unit is powered.

The contrast (bias) supply to the LCD panel and the LCD CCFL backlight both derive power indirectly from a pre-regulator. A software control can shut down the pre-regulator.

For efficiency, it is implemented as a buck switcher operating directly from the battery.

The primary purpose of the pre-regulator is to protect the backlight inverter / ballast from battery voltages that it cannot tolerate and to control current out of the unregulated ballast. The voltage is set to the low side of 5 Volts to reduce battery consumption, while still driving the CCFL with adequate voltage.

Service Manual Technical Overview

External Load (RS-232) Power

There are two power outlet means on the Spot LXi – RS-232 port power and the Braun

PRO 4000 charger.

Two isolated power supplies provide power to each of the external RS-232 ports. This power is available to external devices on pin 9 of each serial connector whenever the software enables the corresponding RS-232 port.

SureTemp Plus Thermometer Interface

The SureTemp Plus OEM module is located in an optional pod and is connected to the main PCB via a flex cable.The Thermometer Probe connection is located on a separate PC board. It is connected to the SureTemp Plus OEM module by a ribbon cable. The electrical interface to the thermometer pod is a 6-pin ribbon connector, Molex 52271-0690 or equivalent.

Braun ThermoScan PRO 4000 Thermometer Interface

The interface to the Braun ThermoScan PRO 4000 thermometer is located in the optional pod and connects to the main PCB via a flex cable. The communications link is a single duplex current loop that also charges the Braun battery pack.

The presence or absence of current passing through the Braun ThermoScan PRO 4000 charge contacts controls the interface charge LED, located within the pod, which mimics the Braun ThermoScan Pro 4000 Base Station (type 6021).

SpO

2

Description

A shielded flat-flex cable connects the user interface sensor connector J8 to the SpO

2 electronics.

The Masimo SpO

module mates to the Masimo Adaptor Board that, in turn, mates to the

Main board. This provides power and communications to the module from the Main board.

The Nellcor SpO

module mounts directly to the Main board. This provides power and communications to the module, and brings the sensor signals to the main board where

EMI and ESD can be controlled. The sensor signals pass through the main board to the mating connector for the shielded flat-flex cable.

Service Manual Technical Overview

Printer Description

All models of the Ap1300 printer use an industry standard RS-232 interface. The default parameters are 9600 baud, 8 data bits, 1 stop bit, and no parity.

Serial data is expected in standard RS-232C format with -12 Volt meaning ‘mark’ or ‘1’ and

+12 Volt a logical ‘0’, with reference to the common ground. The serial data output line,

TxD, transmits XON/XOFF and status information to the host at the same Baud rate and in the same format as the serial data input. The hardware busy line is true (nominal -12 Volt) when busy. Both serial output lines will relax to approximately 0 Volt when the Ap1300 is in sleep mode and the user must allow a short period after awakening before relying on the values of these signals.

The Ap1300 has three operating modes, when not actually printing.

Idle Mode

Sleep Mode

Spool Mode

Ready to accept data, but no data are in the buffer awaiting printing and the printer motor is not running.

Effectively switched off.

Active, but storing data for later printing.

Different color combinations on the front-panel LED indicate the modes. No light is emitted in sleep mode.

No hardware power switch is fitted, as power control is either automatic or by command from the host computer. To save power, the printer enters sleep mode after a period of inactivity, factory-set to 30 seconds, but prorammable from the host. It can also be programmed to stay idle indefinitely or to go to sleep on command.

The Ap1300 utilizes Fujitsu FTP-628MCL 103 printer mechanism, with a fixed (parallel) print head with 384 horizontally-arranged thermal elements. A stepper motor advances the paper and the printing takes place in a single-dot row for each step of the paper. Each printed dot is approximately 1/8 mm square. The printing speed and dot density are controlled according to the battery voltage and the head temperature.

Technical Overview Welch Allyn Spot Vital Signs LXi

The Spot LXi provides two levels of power to fast-charge or to float the battery at fixed voltages using software control. The fast-charge level rapidly brings the battery up to near-full capacity (7 Volts) using software to not overcharge the battery. The float level, set per the manufacturer’s recommendation, slowly tops-off the battery and can stay on indefinitely.

Interference may occur in the vicinity of equipment marked with the following symbol:

Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.

Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects, and people.

Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio,

AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the Spot

Vital Signs LXi is used exceeds the applicable RF compliance level above, the electrocardiograph should be observed to verify normal operation.

If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the electrocardiograph.

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
