The fingertip Pulse Oximeter
Product Operation Scope
The fingertip Oximeter can be used to measure human Hemoglobin Saturation and heart beat through finger. The product is suitable for use in family, hospital (including clinical use in internist/surgery, Anesthesia, pediatrics, intensive care and etc), Oxygen Bar, social medical organizations, physical care in sports (It can be used before or after sports. Operation in sport procedure is not recommended) and etc.
The product is not recommend to monitor patient continuously.

Technical Spefication:
1. Display Format: LED Display;
Hemoglobin Saturation Display: 35 - 99% in two-digit 7-segment digital display;
Pulse Ratio Display: 30 - 240 BPM in 3-digit 7-segment digital display;
Pulse Wave Display: 6-segment bargraph display;
Battery Voltage Low Indication: Through LED signals.
2. Power Requirements: Two heart rate 1.5V Alkali Battery and its voltage adapting range is 2.6 - 3.6 volts.
3. Power Consumption: Smaller than 40mA.
4. Resolution: 1% for Hemoglobin Saturation and + -1 BPM for Pulse Ratio.
5. Measurement Accuracy: + -2% in stage of 70%-99% Hemoglobin Saturation and meaningless when stage being smaller than 70%. + -2 BPM for Pulse Ratio.
6 Measurement Performance in Weak Filling Condition: Oxyhemoglobin and pulse value can be shown correctly when pulse-filling ratio is 0.5%.
7 Interference Resistance Capacity against Ambient Light: Deviation is smaller than + -1% between value of Oxyhemoglobin measured in natural lighting indoor condition and present lighting sources and that measured in dark room.
8 It is equipped with a function switch, through which the Oximeter can be powered off in case no finger is the Oximeter longer than 8 seconds.
Products Function:
1. Operation is simple and convenient.
2. Small in volume,light in weight (total weight is about 50g including batteries.)and covenient in carrying.
3. Power consumption is low and the two originally equipped 2 AAA Batteries can be operated continuously for 30 hours.
4. Low voltage warning will be indicated in visual window when battery voltage is so low that normal operation of the Oximeter might be influenced
