Theory of Operation

1.1 Introduction

The V 12/V 21 is a modular patient monitoring system. The system architecture allows users to

customize, by removal or addition of modules, monitored parameters based on a patient’s monitoring need or acuity level. The modular design simplifies the addition of monitoring

additional parameters with the addition of parameter modules.

The V 12/V 21 focuses on the philosophy of “ Ease of Use” while incorporating traditionally

highly complex monitoring parameters. The user interface minimizes menu layers and excessive

user interaction to simplify patient care. The V 12/V 21 maximizes the amount of viewable data through the use of a portrait display orientation.

The V 21 display uses a 21.3" LCD screen with a resolution of 1600x1200. V 12 display uses a 12.1"

LCD screen with a resolution of 768x1024. The LCD panel gets signals from the main board and gets power from the inverter board, which is driven by the main board through the front

interface connector board.

Alarm Lamp

The monitor has two groups of alarm lamps on the alarm LED board, which is on the front panel. The monitor I/O microprocessor passes the control signal to the LED driver TLC59116 via I2C bus.

Speaker

The speakers provide sound for alarms, heart beats, etc. They are driven by the COM Express

Module and the monitor I/O carrier board.

AC and Battery Status LEDs

The AC and battery status LEDs, located on V Dock (docking station), are controlled by the AC-DC

power board and PMB respectively. The PMB monitors battery status and passes the control

signal to V Dock via connectors.

Recorder

The Recorder module is used to print locally to a thermal recorder. The recorder gets power and

data from the V Hub through the non-Isolated module host communications board. The keypad/

LED is for indication and operation.

V Series Service Manual 046-001131-00 1 - 11

Main Unit Theory of Operation

1.3.3 Processing and Communications System

The processing and communication system mainly consists of two boards: CPU module and

monitor I/O carrier board.

CPU Module

The CPU module is a standard COM Express board, which is the heart of the patient monitor, and

implements a series of tasks including display processing, system control, data storage, and processing, input and output system. The CPU module contains CPU, north-bridge, south-bridge,

DDR2 RAM, real-time clock, EEPROM, etc. It interfaces to the carrier board only, which then

provides interfaces to all other external devices.

Monitor Carrier Board

The monitor I/O carrier board is the CPU module's carrier board and will be described in detail in

section1.3.5 Equipment Interface System on Page 1-14 and Page 1-15.

1.3.4 Power Management System

Li-Ion Battery

• Three removable li-ion batteries are available. The battery compartment door is located at

the lower right of the patient monitor. The battery power is introduced to the power module via the battery interface board and then processed and distributed to V 12 via the power management board.

Internal Backup Battery

• The monitor uses one single-cell li-ion backup battery (P/N: 022-000006-00 SANYO

UR18650W high rate li-ion battery 3.7V 1500mAh). The battery is fixed to the battery interface board.

Battery Interface Board

• The battery interface board serves as an interface between the batteries and the power

management board.

AC-DC Power Board

• The AC-DC power board converts input from AC power, and generates one regulated DC

output of voltage 15V. The output is turned on/off via connection or disconnection of the AC power cord. The power supply provides an indication of AC presence.

• The Power Pin Board acts as a conduit for 12V and 15V to pass between the power supply and

mid and high acuity versions of the V Series patient monitor.
