Usage and function of finger oximeter

The finger oximeter integrates the light sensing technology into the chip, without collecting human blood samples, and monitors the current oxygen content in the blood through light sensing penetration. At the same time, the human pulse rate is detected. Through the pen Segment LCD display, users can easily complete two tests on their fingertips. Finger oximeter is applicable to family, hospital, oxygen bar, community medical treatment and sports health care (it can be used before and after exercise, not recommended to be used during exercise).

The finger oximeter uses light-emitting diodes to emit red and infrared light. It can detect human blood oxygen saturation and pulse rate through the brightness of finger skin and musculoskeletal tissue. Its safety, accuracy and accuracy fully meet the EU CE standard. Finger oximeter has the advantages of small volume, light weight, easy to carry, simple and convenient, and low power consumption.

How to use finger oximeter:

1. When using the finger oximeter for the first time, press the reset key, and the LCD screen displays the standby state


2. Press to open the clamping opening. Put the middle finger of your left hand or right hand into the work bin (you can see the infrared light in the work bin. Note: your fingers should not be crooked, your hands should not be wet, and there should be no foreign matter on the surface of your nails).


3. After the finger is in full contact with the work bin, the LCD displays the detection process. (note that when entering the detection state, keep the tested fingers stable and do not shake up, down, left and right)


4.30 seconds later, release the clamping opening, withdraw the fingers from the working chamber, and the LCD freeze frame test results. % SpO2 at the top of the screen is the blood oxygen index. Min at the bottom of the screen is the pulse rate
