Sphygmomanometer having function of detecting central aortic pulse pressure

Abstract

The invention relates to a sphygmomanometer having a function of detecting central aortic pulse pressure. The sphygmomanometer comprises a front shell, a rear shell, an occluding cuff, an air pump, aninflating / deflating module, a display module, a key module, a control module and a power supply, wherein the occluding cuff is connected with the front shell; the air pump, the inflating / deflating module and the display module are positioned in the front shell; the power supply is connected with the air pump; the air pump is connected with the inflating / deflating module; the control module is connected with the display module; the display module is connected with the key module; and the key module is connected with a rear shell. The invention also relates to a method for detecting the centralaortic pulse pressure. Based on brachial arterial blood pressure pulse wave signals, a multivariate regression model is substituted, and the central aortic pulse pressure is calculated, so that non-intrusive type measurement of the central aortic pulse pressure is realized; when a user measures blood press, measurement of the central aortic pulse pressure is realized, and thus, a measurement method is simple, an operation is relatively simple, and measurement of specialists is not needed.

Description

technical field [0001] The invention relates to a sphygmomanometer with the function of detecting central aortic pressure. Background technique [0002] The measurement of central aortic pressure mostly adopts invasive measurement method. The needle is obliquely inserted into the wrist to measure the pulse pressure wave of the radial artery. Based on Fourier transform or fast Fourier transform, a generalized transfer function is established to obtain the central aortic pressure value. , including: central aortic systolic pressure and aortic diastolic pressure. Due to the high risk of invasive methods and large-scale equipment, it is not easy to use, and foreign companies have begun to develop non-invasive central aortic manometers to measure the brachial and radial arteries, but the analysis technology is complex, which consumes more hardware resources and computational complexity. High, it needs to rely on the professional experience of professionals to operate the tone me...
