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 accumulate 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, assume 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 from their protective bags and before beginning any disassembly or assembly procedures.

Spot Vital Signs LXi 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

2

) 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 Vital Signs LXi uses a fuse and a shunt diode on the main board as well as a fuse in the battery assembly for protection against reverse battery connections. The fuse is located on the main board in the negative battery line. In the event of a reverse battery connection, a blown fuse will require replacement. 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 Vital Signs LXi uses buck switching topology for efficiency and an on-off power latch directly controls the power supply.

37

38

Spot Vital Signs LXi Technical Overview Welch Allyn Spot Vital Signs LXi

Standby Mode

The Standby Mode conserves battery power. The device goes into Standby Mode if it is not used for two minutes. Press any button to bring the Spot Vital Signs LXi out of

Standby Mode.

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.

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

2

and Thermometer Power

A common structure supplies SpO

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

2 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.

Service Manual Spot Vital Signs LXi Technical Overview

39

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.

External Load (RS-232) Power

There are two power outlet means on the Spot Vital Signs 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

2 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

2 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.
