IV Pulse oximeter Service Manual

WARNING: Do not connect this system to outlets with the same circuit

breakers an d fuses that control current to devices such as life-support systems. If this system malfunctions and generates an overcurrent, or when there is an instantaneous current at power ON, the circuit breakers and fuses of the building’s supply circuit may be tripped. Do not use flammable gasses such as anesthetics, or flammable liquids such as ethanol, near this product, because there is danger of explosion.

CAUTION: 1. Malfunctions due to radio waves

(1) Use of radio-wave-emitting devices in the proximity of this

kind of medica l electroni c system may interfere with its operation. Do not bring or use devices which generate radio waves, such as cellular telephones, transceivers, and radio controlled toys, in the room where the system is installed.

(2) If a user brings a device which generates radio waves near

the system, they must be instructed to immediately turn OFF the device. This is necessary to ensure the proper operation of the system.

2. Do not allow fluids such as water to contact the system or peripheral devices. Electric shock may result.

Introduction

Chapter 1 Introduction

1.1 General

The DPM1 Pulse Oximeter is a non-invasive, spot-check, oxygen saturation and pulse rate

monitor. It operates only on battery power using existing DPM1 disposable and reusable finger

and ear sensors labeled for patients ranging from neonates to adults.

Parameters monitored by the DPM1 pulse oximeter include: arterial oxygen saturation (SpO

pulse rate (PR) and pulse strength. The DPM1 pulse oximeter employs a finger SpO

to measure patient’s SpO

screen.

The DPM1is operated and controlled by three buttons, which are Power Button, Backlight

Button and ID Confirm Button. The DPM1 oximter is also capable of data manage and

exporting the patient’s trend data to a PC for printing through the SpO2/communication

multiplex port.

, PR and pulse strength, and all of these are displayed on the LCD

sensor

1.2 Functions

DPM1 has the functions shown as below：

1. Monitoring-----SpO

2. Printing-----patient ID, trend data, measurement time.

3. Power Saving------automatic standby, automatic shutdown.

4. Warning-----memory full, ID full, low battery, standby, technical error.

Printing is available only when the device is equipped with a communication cable and works

with a PC with a printer.

, PR and pulse strength.

1.3 Parameters Measurement

Parameters monitored by DPM1 pulse oximeter includes: SpO2, PR and pulse strength.

DPM1measures SpO

to determine oxygen saturation of hemoglobin.

DPM1 also can determine pulse rate and pulse strength, which are indicated on the LCD

screen after processing.

by pulsating oximetry, which is a continuous and non-invasive method
