According to the method, the numerical values and positions of the diastolic pressure and the systolic pressure can be accurately judged according to the to-be-measured pressure data, and the method has the advantages of self-adaption, self-organization and real-time learning.

Description

technical field [0001] The present invention relates to the field of digital signal processing, and in particular, to a pressure value determination system, method, device and readable storage medium. Background technique [0002] Among many blood pressure measurement methods, the intermittent blood pressure measurement method is widely used due to its advantages of simple operation, short measurement time, and periodic recording of the user's blood pressure measurement value. The intermittent blood pressure measurement method is mainly based on the principle of the Offset sound method. The arterial blood flow is blocked by inflating the cuff, and then the diastolic blood pressure and the systolic blood pressure are judged by listening to the sound of the arterial blood vessels. Electronic sphygmomanometers applying this principle have broad application prospects because of their simple operation and low threshold for use. [0003] However, the existing electronic sphygmoma...

Problems solved by technology

[0003] However, the existing electronic sphygmomanometer generally chooses the fixed proportional coefficient method or the inflection point method when determining the diastolic and systolic blood pressure. However, different cases require different proportional coefficients. The accuracy of a single fixed ratio is poor, and some test samples do not have Obvious inflection point, the inflection point method cannot be used to determine the pressure value, so there is currently no pressure test scheme with high accuracy
