Control target value automatic detection device based on blood pressure beat-to-beat detection device and detection method of control target value automatic detection device

Abstract

The invention relates to a control target value automatic detection device based on a blood pressure beat-to-beat detection device and a detection method of the control target value automatic detection device and belongs to the field of blood pressure continuous detection of a radial artery. The invention solves the problems that an existing blood pressure detection device cannot detect a servo control target value at any time; due to reasons such as variation of vascular tone or position offset of an oversleeve, the variation of a target value is caused and the blood pressure cannot be continuously and accurately detected; and when a new target value is to be determined, system operation needs to be interrupted so as to cause fault and loss of important monitoring data. The control target value automatic detection device further comprises a wavelet filter and amplification module, a control target value I0 calculating module and a high frequency pressure wavelet generating module. When a control target value needs to be detected, a mean blood pressure signal output switch of a pressure output and calculation module is switched on, the high frequency pressure wavelet generating module generates a high frequency pressure wave which takes a mean blood pressure value as the center; the current control target value I0 is obtained by the control target value I0 calculating module; and the current control target value I0 is compared with PGdc which is detected in real time and the pressure of a cuff is regulated so as to obtain a pressure waveform and a blood pressure value at the moment. The control target value automatic detection device and the detection method thereof are used in the field of blood pressure detection.

Description

technical field [0001] The invention belongs to the field of radial artery blood pressure continuous detection. Background technique [0002] Cardiovascular and cerebrovascular diseases with hypertension, arteriosclerosis, and stroke as the main symptoms seriously endanger the health of our people. The death due to cardiovascular and cerebrovascular diseases has accounted for the first cause of death among Chinese residents, about 35% to 40%. become an important public health problem in our country. However, there are still many unknown parts of the pathogenesis of hypertension, which is the cause of various cardiovascular and cerebrovascular diseases, because blood pressure changes dynamically at every moment and every heart beat. To find out the cause and pathogenesis of hypertension, it is necessary to increase blood pressure detection and obtain more data on blood pressure changes. Although the currently used intermittent detection sphygmomanometer has become an indisp...
