Embodiment Construction

[0036] In order to solve the interference problem caused by user activities in blood oxygen saturation detection, a three-wavelength blood oxygen saturation detection method and device are proposed according to the embodiment of the present invention. Use an LED with an isoabsorptive wavelength.

[0037] Isabsorbing point wavelength refers to the wavelength at which oxygenated hemoglobin and reduced hemoglobin have the same absorption rate of light, that is, figure 1 At the intersection of the absorbance curves of the two proteins in , the typical value is 810nm. The characteristics of the wavelength of the equal absorption point are: the received normalized AC optical signal value I equal It is only related to the LED intensity, light path loss, and the amplification factor of the receiving circuit, but has nothing to do with the actual blood oxygen value of the human body. Therefore, interference signals caused by activities can be detected and calculated accordingly.

Abstract

The invention discloses a three-wavelength oxyhemoglobin saturation detection method and device and wearable equipment. The method comprises the steps of oxyhemoglobin detection, error detection, error calculation and oxyhemoglobin calculation. By means of the three-wavelength oxyhemoglobin saturation detection method and device and the wearable equipment comprising the device, the detection errorcaused by noise due to movement can be removed, and a more accurate oxyhemoglobin saturation detection result can be obtained.

Description

technical field [0001] The present invention relates to a blood oxygen saturation detection method and device, in particular to a three-wavelength blood oxygen saturation detection method and device and a wearable device including the device. Background technique [0002] Blood oxygen saturation is the percentage of the capacity of oxygen-bound oxyhemoglobin in the blood to the total hemoglobin capacity that can be combined, that is, the concentration of blood oxygen in the blood. The blood oxygen saturation content is generally expressed by the percentage of oxygenated hemoglobin (Hbo2) in the blood to the total hemoglobin, and its expression is: [0003] Spo2=C Hbo2 / (C Hbo2 +C Hb )×100%, [0004] where C Hbo2 is the oxygenated hemoglobin content in the blood, C Hb To restore hemoglobin content. [0005] Non-invasive measurement of blood oxygen saturation is commonly used with dual-wavelength photoplethysmography (PPG), that is, using oxyhemoglobin and reduced hemog...
