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 etc.). This device is not intended for continuous monitoring.

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 fingers into a fingertip photoelectric sensor for diagnosis, and a display screen will directly show measured value of Hemoglobin Saturation.

Classification

Class II b, (MDD93/42/EEC IX Rule 10)

Features
A. Operation of the product is simple and convenient.
B. The product is small in volume, light in weight (total weight is about 50 g including batteries) and convenient in carrying.
C. Power consumption of the product is low and the two originally equipped AAA batteries can be operated continuously for 20 hours.
D. The product will enter standby mode when no signal is in the product within 5 seconds.
E. Display direction can be changed automatically, easy to view.

Major Applications and Scope of Application
The Pulse Oximeter can be used in measuring the pulse oxygen saturation and pulse rate through finger. The product is suitable for being used in family, hospital, oxygen bar, community healthcare, physical care in sports (It can be used before or after doing sports and it is not recommended to use the device during the process of having sport) and etc.

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.

Principle

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 device 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 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.

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 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
   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.

Clinical Restrictions

1. As the measure is taken on the basis of arteriole pulse, substantial
   pulsating blood flow 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.
