1.4 Indication for Use
The Fingertip Pulse Oximeter is a non-invasive device intended for the spot-check of oxygen saturation of arterial hemoglobin (SpO2) and the pulse rate of adult and pediatric patients in home and hospital environments (including clinical use in
internist/surgery, anesthesia, intensive care ect.). This device is not intended for continuous monitoring.
2 Overview
The pulse oxygen saturation is the percentage of HbO2 in the total Hb in the blood, so-called the O2 concentration in the
blood. It is an important bio-parameter for the respiration. For the purpose of measuring the SpO2 more easily and accurately, 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 ngers into a ngertip photoelectric sensor for diagnosis, and a display screen will
directly show measured value of Hemoglobin Saturation.
2.1 Classification
Class II a, (MDD93/42/EEC IX Rule 10)
2.2 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.
2.3 Major Applications and Scope of Application
The Pulse Oximeter can be used to measure human Hemoglobin Saturation and pulse rate through nger, 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 monoxide, the device is not recommended to be used under this circumstance.
2.4 Environment Requirements
Storage Environment
a)Temperature: -40°C~+60°C
b) Relative humidity: ≤95%
c) Atmospheric pressure: 500hPa~1060hPa
Operating Environment
a) Temperature: 10°C~40°C
b) Relative Humidity: ≤75%
c) Atmospheric pressure: 700hPa~1060hPa
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 (HbO2) in glow & near-infrared zones. Operation principle of the instrument is: Photoelectric Oxyhemoglobin Inspection Technology is adopted
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 nger-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 nger should be placed properly (see the attached illustration of this manual, Figure 5), or else it may cause inaccurate
measurement.
2. The SpO2 sensor and photoelectric receiving tube should be arranged in a way with the subject’s arteriole in a position
there between.
3. The SpO2 sensor should not be used at a location or limb tied with arterial canal or blood pressure cuff or receiving
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 uorescent 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 ow of subject is required. For a
subject with weak pulse due to shock, low ambient/body temperature, major bleeding, or use of vascular contracting
drug, the SpO2 waveform (PLETH) will decrease. In this case, the measurement will be more sensitive to interference.
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 SpO2 determination by this monitor may be inaccurate.
3. The drugs like dopamine, procaine, prilocaine, lidocaine and butacaine may also be a major factor blamed for serious
error of SpO2 measure.
4. As the SpO2 value serves as a reference value for judgement of anemic anoxia and toxic anoxia, some patients with
serious anemia may also report good SpO2 measurement.
