Wearable vital signs monitoring device and blood pressure detection method based on light sensing

Abstract

The invention discloses optical sensing-based wearable vital sign monitoring equipment and a blood pressure detecting method. The equipment disclosed by the invention comprises a watch body shell, a power supply module, a voltage stabilizing module, a control module, a sensor module, mode switching buttons and a display module; the power supply module, the voltage stabilizing module, the control module and the sensor module are arranged in the shell; the mode switching buttons are arranged on the periphery of the shell; the display module is arranged on the upper surface of the shell; two windows and three light transmitting holes are formed in the lower surface of the watch body shell. According to the optical sensing-based wearable vital sign monitoring equipment and the blood pressure detecting method, a human body characteristic parameter K is set according to different peripheral resistance and arterial wall elasticity at the wrists of different persons at different times, and two correction factors, alpha and beta, are also set according to a general change rule of the blood pressure at different time periods, so that more accurate blood pressure parameters aiming at different individuals are calculated.

Description

technical field [0001] The invention belongs to the field of health wearable devices, and provides a wearable vital sign monitoring device based on light sensing and a blood pressure detection method thereof. Background technique [0002] The most representative vital sign parameters of the human body are nothing more than body temperature, heart rate, blood pressure, etc. Effective detection of these parameters can reflect the wearer's physiological condition well and then carry out early warning and adjustment. However, how to measure blood pressure conveniently and accurately has always been a difficult problem in the field of health wearable devices. An essential part of the traditional blood pressure measurement method is the pneumatic pump, and then constitutes a dynamic blood pressure testing system formed around the pneumatic pump. The main disadvantage of this measurement method is that there are too many "deliberate" requirements for the measurement process, and t...

AI Technical Summary

Problems solved by technology

The main disadvantage of this measurement method is that there are too many "deliberate" requirements for the measurement process, and the state of the measurement is mostly stable and calm. At this time, the measured data is quite different from the peak value that the blood pressure will really reach when the human body is exercising. , can not really achieve the prevention and early warning

Second, the continuous extrusion of the wrist or arm during the test also caused an extremely uncomfortable user experience

The third is that the circuit design combined with the air pump is relatively complicated, the volume is quite large, it is not convenient to carry, and the cost is too high
