Indication for Use

The Fingertip Pulse Oximeter is a non-invasive device intended for the spot- check of oxygen saturation of arterial hemoglobin (SpO:z) 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.

Overview

The pulse oxygen saturation is the percentage of HbO2 in the total Hb in the blood, so-called the 0 2 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 Oxi:meter. 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 Ila , (MDD93/42/EEC IX Rule IO)

Features

• Operation of the product is simple and convenient.
• The product is small in volume, light in weight (total weight is about S0g 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.

Major Application 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 1upervision 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.

E nvironment Requirements
Storage Environment

1. Temperature: -40 ‘C ~ ~0 ‘C
2. Relative humidity: ‘595%
3.  Atmospheric pressure: 500 hPa ~ l060 hPa

Operating Environment

1. Temperature: lO ‘C ~ 40 ‘C
2. Relative Humidity: 95%
3. Atmospheric pressure: 700 hPa ~ l060 hPa

Principle and Caution

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. The 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 wavelengths 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 Sp()2 sensor should not be used at a location or limb tied with arterial canal or blood pressure cuff or receiving an 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 a 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, the substantial pulsating blood flow of the subject is required. For a subject with weak pulse due to shock, low ambient/body temperature, major bleeding, or use of the 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 this salicylic hemoglobin, and some with icterus problem, the SpO2 determination by this monitor may be inaccurate.
3. The drugs like dopamine, procaine, prilocaine, lidocaine and but came may also be a major factor blamed for serious error of Sp02 measure.
4. AB the SpO2 value serves as a reference value for judgment of anemic anoxia and toxic anoxia, some patients with serious anemia may also report good SpO2 measurement.

Accessories

• One hanging rope;
• Two batteries(optional)
• One User Manual
