The disclosure provides a measuring device and method for measuring blood pressure, belonging to the field of electronic equipment. The measuring device includes: a body and an inflatable part connected to the body; the inflatable part includes an inner cavity for fixing and wearing the measuring device on the body; the body includes a PPG module, a micropump, an air pressure sensor and a signal processing unit, and the PPG The module is used to collect the PPG signal; the micropump is used to inflate or deflate the inner cavity; the air pressure sensor is used to detect the pressure wave signal of the inner cavity; the signal processing unit is used to convert the stable state and the changing state of the PPG signal The critical time point is determined as the diastolic blood pressure time point, the time point when the amplitude of the PPG signal changes to the first preset threshold is determined as the systolic blood pressure time point, and the corresponding diastolic blood pressure measurement value is obtained according to the diastolic blood pressure time point and the systolic blood pressure time point and the corresponding systolic blood pressure measurements. The disclosure improves the measuring accuracy, can reduce the volume of the measuring device, and the measuring device with small volume is easy to carry and measure.
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 ...
