How to use finger oximeter

The finger oximeter integrates light sensing technology into the chip, without collecting human blood samples, and monitoring the current oxygen content in the blood through light sensing. At the same time, the human pulse rate is detected. Through the pen-segment LCD announcement, users can see at a glance and easily complete two tests at their fingertips. The finger oximeter is suitable for families, hospitals, oxygen bars, community medical treatment and sports health care (can be used before and after exercise, not recommended for use during exercise).



The finger oximeter uses light-emitting diodes to emit red light and infrared light, and the brightness of the finger skin and musculoskeletal tissues is detected to detect human blood oxygen saturation and pulse rate. The safety, accuracy, and accuracy are fully in line with EU CE standard. The finger oximeter is small in size, light in weight, convenient to carry, simple and convenient, and low power consumption.
1. When using the finger oximeter for the first time, press the Reset button, the LCD screen displays the standby state

2. Press the opening clamp. Put your left hand or right middle finger into the work compartment (you can see the infrared light in the work compartment. Note: Don’t pinch your fingers, don’t wet your hands, and don’t have foreign objects on the nail surface).

3. After the finger is in full contact with the working chamber, the LCD will display the detection process. (Attention, enter the detection state, keep the tested finger stable, do not shake up and down, left and right)

4. After 30 seconds, loosen the clamp, withdraw your finger from the working compartment, and the LCD freezes the test result. The %SpO2 at the top of the screen is the blood oxygen indicator. Min at the bottom of the screen is the pulse rate

END Precautions
According to medical analysis, blood oxygen content (%SpO2) is greater than or equal to 95, which is a normal indicator; pulse rate (/Min) is between 60-100, which is a normal indicator. If your detected values ​​do not meet the above two indicators, please monitor for 2-3 times at different time points and maintain continuous monitoring for 2-3 days. If the values ​​still do not meet the standard values, you are recommended to go to the hospital for detailed consultation .
The principle of the finger oximeter is based on the absorption spectrum characteristics of reduced hemoglobin and oxygenated hemoglobin in the red and near-red light regions, using Lambert Beer's law to establish an empirical formula for data processing. The working principle of the finger oximeter uses photoelectric oximetry technology combined with volume pulse tracing technology. Two beams of light (red light at 660nm and near-infrared light at 940nm) of different wavelengths are used to illuminate the tip of the human nail through a perspective finger sensor. The measurement signal is obtained by the photosensitive element, and the obtained information is processed by the electronic circuit and the microprocessor, and the measurement result is displayed by two sets of LEDs.
