CONTEC Pulse Oximetrr

Figure 1 Working principle The principle of the oximeter is as follows: According to the spectral absorption characteristics of reduced hemoglobin (Hb) and oxygenated hemoglobin (HbO2) in the glow region and near-infrared region, Lambert Beer's law is used to establish an empirical formula for data processing. The working principle of the device is: According to the capacitive pulse scanning recording technology and the photoelectric oxyhemoglobin detection technology, two beams of light of different wavelengths are focused on the tip of the human nail through the fluoroscopy clamp finger sensor. Then the measured signal is obtained through the photosensitive element, processed by the electronic circuit and the microprocessor, and the obtained information is displayed on the screen.
