A pulse detection control method

Abstract

The invention provides a pulse detecting and controlling method. According to the method, a determinacy point is set in a pulse curve chart, then according to the amplitude value detection on follow-up detecting points at intervals, whether a pulse signal is too strong or too weak or not is judged, if the signal is too strong, the difference value between amplitude values of the follow-up detecting points and the value of the first determinacy point will be beyond a certain range, and in this way, the amplification factor of an amplifier is controlled to be decreased gradually until requirements are met. Accordingly, within the range, a screen can be just filled with the amplitude values of the pulse curve chart, and the signal will not be beyond the range of the screen obviously, which facilitates the analysis of the pulse signal in the follow-up period. In this way, in the process of detecting the pulse signal, a user does not need to purposely adjust the tightness degree of a bandage, and the pulse detecting and controlling method is simple and convenient to implement.

Description

technical field [0001] The invention relates to the technical field of pulse wave signal detection, in particular to a pulse detection control method. Background technique [0002] The periodic contraction and relaxation of the human ventricle leads to the contraction and relaxation of the aorta, making the blood flow pressure propagate from the root of the aorta along the entire arterial system in the form of waves, and this wave becomes the pulse wave. The comprehensive information of the shape, intensity, speed and rhythm presented by the pulse wave largely reflects the blood flow characteristics of many physiological and pathological conditions in the human cardiovascular system. [0003] In modern medicine, regardless of traditional Chinese medicine or Western medicine, the method of analyzing the physiological and pathological information of the human body through the waveform of the human pulse wave has been paid more and more attention. At present, in order to objec...

But it still has the following disadvantages: due to the different degrees of tightness of the wristband or the strength of each person's pulse signal, the signal of the pressure sensor will be strong or weak, so that the amplitude of the pressure displayed on the display sometimes changes when the signal is strong. Beyond the scope of the screen, when the signal is weak, the amplitude is not obvious, and the analysis of the pulse curve in medicine is not the analysis of the pulse strength, but the shape of the entire pulse curve to analyze the pulse beating law, rather than It is to analyze the strength of the pulse. Therefore, if the amplitude of the pulse signal is not adjusted, it will cause inconvenience to the analysis of the pulse signal in the future. In the prior art, it is generally necessary to adjust the tightness of the strap according to the amplitude of the pulse curve. So that the entire pulse curve can be displayed completely and clearly on the screen. This method is cumbersome and inconvenient
