 High temperature or high pressure steam disinfection of the oximeter is not permitted. Refer to User Manual in the relative
chapter for instructions of cleaning and disinfection.
 Do not have the oximeter immerged in liquid. When it needs cleaning, please wipe its surface with medical alcohol by soft
material. Do not spray any liquid on the device directly.
 When cleaning the device with water, the temperature should be lower than 60°C.

 The device may not work for all patients. If you are unable to achieve stable readings, discontinue use.
 The update period of data is less than 5 seconds, which is changeable according to different individual pulse rate.
 The waveform is normalized.Please read the measured value when the waveform on screen is equably and steady-going,
Here this measured value is optimal value. And the waveform at the moment is the standard one.
 If some abnormal conditions appear on the screen during test process, pull out the finger and reinsert to restore normal
use.
 The device has normal useful life for three years since the first electrified use.
 The hanging rope attached the product is made from Non- allergy material, if particular group are sensitive to the hanging
rope, stop using it. In addition, pay attention to the use of the hanging rope , do not wear it around the neck avoiding cause
harm to the patient.
 The instrument dose not have low-voltage alarm function, it only shows the low-voltage.please change the battery when
the battery energy is used out.
 When the parameter is particularly, The instrument dose not have alarm function.Do not use the device in situations where
alarms are required.
 Batteries must be removed if the device is going to be stored for more than one month, or else batteries may leak.
 A flexible circuit connects the two parts of the device. Do not twist or pull on the connection.
1.4 Indication for Use
The Fingertip Pulse Oximeter is a non-invasive device intended for the spot-check of oxygen saturation of arterial hemo-
globin (SpO
) and the pulse rate of adult and pediatric patients in home and hospital environments (including clinical use in
2
internist/surgery, anesthesia, intensive care ect.). This device is not intended for continuous monitoring.
2 Overview
The pulse oxygen saturation is the percentage of HbO
blood. It is an important bio-parameter for the respiration. For the purpose of measuring the SpO
rately, our company developed the Pulse Oximeter. At the same time, the device can measure the pulse rate simultaneously.
The Pulse Oximeter features in small volume, low power consumption, convenient operation and being portable. It is only
necessary for patient to put one of his fingers into a fingertip photoelectric sensor for diagnosis, and a display screen will
directly show measured value of Hemoglobin Saturation.
2.1 Features
• Operation of the product is simple and convenient.
• The product is small in volume, light in weight (total weight is about 50g including batteries) and convenient in carrying.
• Power consumption of the product is low and the two originally equipped AAA batteries can be operated continuously for
20 hours.
• The product will enter standby mode when no signal is in the product within 5 seconds.
• Display direction can be changed automatically,easy to view.
2.2 Major Applications and Scope of Application
The Pulse Oximeter can be used to measure human Hemoglobin Saturation and pulse rate through finger, and indicate the
pulse intensity by the bar-display. The product is suitable for use in family, hospital (Ordinary sickroom), Oxygen Bar, social
medical organizations and also the measure of saturation oxygen and pulse rate.
The product is not suitable for use in continuous supervision for patients.
The problem of overrating would emerge when the patient is suffering from toxicosis which caused by carbon mon-
oxide, the device is not recommended to be used under this circumstance.

3 Principle and Caution
3.1 Principle of Measurement
Principle of the Oximeter is as follows: An experience formula of data process is established taking use of Lambert Beer
Law according to Spectrum Absorption Characteristics of Reductive Hemoglobin (Hb) and Oxyhemoglobin (HbO
near-infrared zones. Operation principle of the instrument is: Photoelectric Oxyhemoglobin Inspection Technology is adopt-
ed in accordance with Capacity Pulse Scanning & Recording Technology, so that two beams of different wavelength of lights
can be focused onto human nail tip through perspective clamp finger-type sensor. Then measured signal can be obtained
by a photosensitive element, information acquired through which will be shown on screen through treatment in electronic
circuits and microprocessor.
Figure 1 Operating principle
3.2 Caution
1. The finger should be placed properly (see the attached illustration of this manual, Figure 5), or else it may cause inaccurate
measurement.
2. The SpO
sensor and photoelectric receiving tube should be arranged in a way with the subject's arteriole in a position
2
there between.
3. The SpO
sensor should not be used at a location or limb tied with arterial canal or blood pressure cuff or receiving
2
intravenous injection.
4. Make sure the optical path is free from any optical obstacles like rubberized fabric.
5. Excessive ambient light may affect the measuring result. It includes fluorescent lamp, dual ruby light, infrared heater,
direct sunlight and etc.
6. Strenuous action of the subject or extreme electrosurgical interference may also affect the accuracy.
7. Testee can not use enamel or other makeup.
3.3 Clinical Restrictions
1. As the measure is taken on the basis of arteriole pulse, substantial pulsating blood flow of subject is required. For a sub-
ject with weak pulse due to shock, low ambient/body temperature, major bleeding, or use of vascular contracting drug,
the SpO
waveform (PLETH) will decrease. In this case, the measurement will be more sensitive to interference.
2
2. For those with a substantial amount of staining dilution drug (such as methylene blue, indigo green and acid indigo blue),
or carbon monoxide hemoglobin (COHb), or methionine (Me+Hb) or thiosalicylic hemoglobin, and some with icterus
problem, the SpO
determination by this monitor may be inaccurate.
2
3. The drugs like dopamine, procaine, prilocaine, lidocaine and butacaine may also be a major factor blamed for serious
error of SpO
measure.
2
4. As the SpO
value serves as a reference value for judgement of anemic anoxia and toxic anoxia, some patients with
2
serious anemia may also report good SpO
