leak.
A exible circuit connects the two parts of the device. Do not twist or pull on the connection.
2 Overview
The pulse oxygen saturation is the percentage of HbO, in the total Hb in the blood, so-called the 0, 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 user to put one of his ngers into a ngertip photoelectric sensor for diagnosis, and a display
screen will directly show measured value of Sp0.
2.1 Classication:
Class II b(MDD93/42/EEC IX Rule 10) Class II (U.S.FDA)
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 operat-
ed continuously for 20 hours.
The product will automatically be powered off when no signal is in the product within 5 seconds.
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 with sporting and elavation activities.
The product is not suitable for use in continuous supervision for user.
The problem of overrating would emerge when the 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 Operating Environment
a) Temperature: -40°C--,60°C a) Temperature: 10°C-40°C
b) Relative humidity ≥95% b) Relative Humidity: ≥75%
c) Atmospheric pressure :500hPa-1060hPa 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 (11b) and Oxyhemoglobin
(HbO,) 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.
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 receiv-
ing 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. User can not use enamel or other makeup.
3.3 User 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 icteros problem, the Sp0a 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 users with
serious anemia may also report good SpO2, measurement
