Abstract

The invention provides a measuring device and method for measuring blood pressure, and belongs to the field of electronic equipment. The measuring device comprises a device body and an inflatable partconnected with the device body; the inflatable part comprises an inner cavity and is used for fixedly wearing the measuring device on the body part; the device body comprises a PPG module, a micropump, a baroceptor and a signal processing unit, and the PPG module is used for collecting PPG signals; the micropump is used for inflating or deflating the inner cavity; the baroceptor is used for detecting pressure wave signals of the inner cavity; the signal processing unit is used for determining a critical time point of the stable state and the change state of a PPG signal as a diastolic pressure time point, determining a time point when the amplitude of the PPG signal is changed to a first preset threshold value as a systolic pressure time point, and obtaining a corresponding diastolic pressure measurement value and a corresponding systolic pressure measurement value according to the diastolic pressure time point and the systolic pressure time point. According to the measuring device and method, the measuring accuracy is improved, the size of the measuring device can be reduced, the measuring device with the small size is convenient to carry, and measurement is facilitated.

Description

technical field [0001] The present disclosure relates to the field of electronic equipment, in particular to a measuring device and method for measuring blood pressure. Background technique [0002] Human blood pressure refers to the pressure produced by the pulsating blood flow in the blood vessel on the blood vessel wall laterally and perpendicular to the blood vessel wall. for low pressure. Blood pressure is an important indicator of health monitoring, which can reflect the health status of the human body. Therefore, how to measure blood pressure conveniently has become a hot issue. [0003] Blood pressure is often measured with a cuff sphygmomanometer, see Figure 1a , the cuff-type sphygmomanometer includes a body 101 and a cuff 102 connected to the body, the structure of the body 101 is as follows Figure 1b As shown, the body 101 includes a micropump 1011 , an air pressure sensor 1012 and a signal processing unit 1013 , and the air pressure sensor 1012 is connected ...
