Product Name: Finger clip oximeter

Model/Specification: M3, M5, M8

Scope of application: Suitable for monitoring patients' pulse oxygen saturation and pulse rate.

Structural composition: The finger clip oximeter consists of a battery and a main unit

Contraindications: This product is not suitable for continuous measurement

Product operating environment: The pulse oximeter software needs to be burned into a designated chip to form firmware before it can be used. Not dependent on the network and not adapted to the network.

Product quality characteristics: The firmware runs stably and reliably, and is specifically designed to measure human blood oxygen saturation and pulse rate. After booting up, connect and insert your finger, and the program will automatically enter

Measure the operational status without the need for manual intervention

The measurement principle of a oximeter is based on the absorption spectra of reduced hemoglobin (Hb) and oxygenated hemoglobin (HbO2) in the red and near red light regions

Based on the characteristics, establish an empirical formula for data processing using Lambert Beer's law. The working principle of this instrument adopts photoelectric blood oxygen detection technology

Combining volume pulse recording technology, two different wavelengths of light (660nm red light and 905nm near-infrared light) are used to transmit through a finger clip sensor

The device illuminates the fingertips of the human body and obtains measurement signals through photosensitive components. The obtained information is processed by electronic circuits and microprocessors and displayed on a screen
