heart rate and blood oxygen saturation measurement principles include two parts, spectrophotometry and blood plethysmography: the skin is irradiated by red light and infrared light, and is received by a sensor receiving module after being absorbed by skin blood, because the absorption coefficients of the skin, muscle, fat, venous blood, pigment, bone and the like on the two lights are constant, only the Hb02 and Hb concentration in arterial blood flow change along with the arterial periodicity of blood, so that the output signal strength changes along with the arterial periodicity, the periodically changed signals are processed, the ratio of the infrared light absorption amount to the red light absorption amount is measured by a spectrophotometry according to the difference of the absorption rate of oxyhemoglobin (Hb 02), and the oxyhemoglobin oxygenation degree can be determined, and the corresponding oxyhemoglobin saturation and heart rate can be measured.
S4, outputting the data to a real-time monitoring module through a Bluetooth module;
s5, the hearing aid chip transmits blood oxygen saturation data to the mobile phone APP end and the affiliated mobile phone APP end through Bluetooth.
In addition, the technical solutions of the embodiments of the present invention may be combined with each other, but it is necessary to be based on the fact that those skilled in the art can implement the technical solutions, and when the technical solutions are contradictory or cannot be implemented, the combination of the technical solutions should be considered as not existing, and not falling within the scope of protection claimed by the present invention.
