1. INTRODUCTION
1.1 Brief Introduction
Thank you for purchasing the Pulse Oximeter. The main functions of the device are to measure
Haemoglobin Saturation (SpO2) and Pulse Rate (PR) value of single patient and transmit data by
GPRS or USB. Please read the instruction manual carefully before using the device.
Note: The illustrations used in this manual may differ slightly from the actual product.
1.2 Safety Information
Conception of Warning, Caution and Note
The Warning, Caution and Note in this document are special information in favor of users’ operation.
★ Warning
Indicate that maybe some potential hurt or damage to patients or device.
★ Caution
Make user take a serious attitude toward the incorrect operation, which are likely to incur some
life-threatening incidents.
★ Note
Serve as a pivotal notice to avoid preventable incidents during application of this equipment.
Warnings!
Before use, please read the manual directions, all precautions and specifications carefully. Our
company will assume no warranty for using the device improperly.
The user must check that the device functions safely and ensure that it is in proper working
3
MD300W4 PULSE OXIMETER
conditions.
Do not use the pulse oximeter in the presence of flammable anesthetics, vapors or liquids.
Do not use the pulse oximeter in an MRI or CT environment which is the source of some electric
noise to influence the accuracy of the equipment and following measurement.
This equipment is intended only as an adjunct in patient assessment, and the measurement results
only serve as a reference for any relevant treatment.
Prolonged use of the probe/sensor or the patient’s condition may require changing the sensor site
periodically. Change the sensor site and check skin integrity, circulatory status, and correct
alignment at least every 4 hours. Prolonged use may cause blisters, skin deterioration, and
discomfort.
Connect the sensor correctly; please follow the directions for use of any accessories.
The sensor is a sensitive device so please strictly follow the sensor application instructions.
Use only the SpO2 sensors supplied by our company. Use of sensors not intended for the device
may cause wrong alarm.
The malfunction of sensor may cause inaccurate measurement result.
The disposable accessories should not be cycled.
The device does not require periodic calibration and maintenance, except replacing batteries.
When connecting this equipment to other peripherals, make sure that you are qualified operator to
operate this device. Any peripherals must be certified according to the protocol of IEC 950 and IEC
60601-1-2. Any input/output device should be following the protocol of IEC 60601-1-2.
Cautions
This device is intended for use by persons trained in professional health care. The operator must be
4
MD300W4 PULSE OXIMETER
thoroughly familiar with the information in the manual before using the device.
The surface of the device can be wiped with alcohol gently. The device is strictly forbided to contact
with strong acid or alkali.
Unplug the sensor from the pulse oximeter before cleaning or disinfecting to prevent the sensor or
pulse oximeter from being damaged, and also to protect the user under safety situation.
Clean the probe with an H2O solution and a neutral detergent.
Don’t submerge the device or probe into any liquid. Do not use the device in autoclave (sterilizer).
The materials that contact with human bodies are all non-toxic.
If the specification or function of the device is abnormal during measuring, stop measuring
immediately and consult us.
Federal Law (U.S.A) restricts this device to sale by or on the order of a physician.
Notes
Application of this device in the background of electromagnetic areas may influence the
measurement accuracy such as electro-surgery environment.
SpO2 measurement may be adversely affected in the presence of strong ambient light. Shield the
sensor area (with a surgical towel, for example) if necessary.
Dyes introduced into the bloodstream, such as methylene blue, indocyanine green, indigo carmine,
and fluorescein, may adversely affect the accuracy of the SpO2 measurement.
Any condition that restricts blood flow, such as using a blood pressure cuff or extremes in systemic
vascular resistance, may cause a failure to detect the accurate SpO2 value and pulse rate.
Remove fingernail polish or artificial fingernails before applying SpO2 probes. Fingernail polish or
artificial fingernails may lead to inaccurate SpO2 readings.
5
MD300W4 PULSE OXIMETER
Optical cross talk can occur when two or more probes are located in adjoining area. It can be
eliminated by covering each site with opaque material. Optical cross talk may adversely affect the
accuracy of the SpO2 readings
Obstructions or dirt on the sensor’s emission or receiving windows may cause a sensor failure.
Make sure there are no obstructions and the sensor is clean.
Hazards arising from software errors have been minimized. Hazard analysis conforms to meet
ISO14971: 2000 and EN60601-1-4: 1996. Significant levels of dysfunctional hemoglogins, such as
carboxyhemoglogin or methhemoglobin, will spawn an affection of the accuracy of the SpO2
measurement.
For routine equipment maintenance, please refer to the service procedures at the specific sections
as indicated in the manual.
The circuit diagrams, the list of components, the illustration of diagrams, and the detailed rules of
calibration, are provided exclusively to professional personnel authorized by our company.
Dispose of the device or its accessories end of life in accordance with the local ordinances and
regulations, otherwise, discarding them as you like may cause pollution to the environment.
As to other attentions, please carefully look through the specific chapter in this instruction manual.
1.3 Intended Use
This pulse oximeter is a portable, non-invasive device intended for continuous monitoring or spot

2.Excessive patient movement;
3.Significant levels of dysfunctional hemoglobins (e.g.,carboxyhemoglobin or methemoglobin);
4.Exposure to excessive light such as xenon light sources, bilirubin lamps or direct sunlight (should this
occur, cover the sensor and application site with opaque material);
5.Intravascular dyes such as indocyanine green or methylene blue.
Loss of pulse signal may be caused by:
1. Patient is in cardiac arrest or shock;
2. Applying the sensor too tightly;
3. Inflating a blood pressure cuff on the extremity where the sensor is attached;
4. Patient who has hypotension, severe vasoconstriction, severe anemia or hypothermia;
