Radial artery pulse wave based cardiovascular function assessment system

Abstract

The invention relates to a radial artery pulse wave based cardiovascular function assessment system comprising a pulse and blood pressure acquisition system and a computer analysis system. The pulse and blood pressure acquisition system comprises a sphygmomanometer cuff, a pulse clip, a pulse sensor and a pulse acquisition box. The computer analysis system comprises a computer system, analysis software, a printer and a power source. By using the system, users can obtain the index values for reflecting the cardiovascular health conditions, specific cardiovascular health conditions and intervention measures corresponding to the specific cardiovascular health conditions. In the system, when the pulse wave related data are acquired, the pulse clip is used for fixing the pulse sensor and the degree of tightness of the pulse clip is adjusted by a control chip according to the strength of the pulse signals, thus enabling data acquisition to be more rapid and accurate. When the blood pressure related data are acquired, automatic and uniform aeration can be realized, and acquisition is carried in the aeration stage, thus accelerating the speed of data acquisition. In addition, a special power system is used for supplying power to the pulse and blood pressure acquisition system, thus ensuring the safety of users.

Description

technical field [0001] The invention relates to sensor technology and biomedical engineering, in particular to a cardiovascular function evaluation system based on radial artery pulse waves. Background technique [0002] In the mid-1980s, the former Soviet scholar N. Buchmann first proposed that in addition to the healthy state (the first state) and the diseased state (the second state), the human body also has an intermediate state of non-health and non-disease, called The "third state" is the "sub-health state" we often refer to. Clinical experiments have proved that various physiological systems in the human body (such as the circulatory system, respiratory system, etc.) are coupled to each other, and the cardiovascular system is the most important and relatively comprehensive in reflecting human health. With the improvement of people's living standards, cardiovascular disease is increasingly harmful to human life and health. Cardiovascular disease is one of the main cau...

Problems solved by technology

[0004] The purpose of the present invention is to analyze the cardiovascular health status of the human body by collecting relevant data including blood pressure and pulse waves proposed for the above content, which can objectively reflect the health status of the human body from one aspect, and aim at the existing cardiovascular health status. The blood pressure measurement in the blood vessel detection device is not fast enough, the pulse signal acquisition is not accurate enough, and the existing cardiovascular detection device uses a USB power interface to supply power to the air pump part that inflates the sphygmomanometer cuff directly connected to the human body, and the personal safety of the user cannot be fully guaranteed. The problem of protection, the patent of the present invention proposes a cardiovascular function evaluation system based on the radial artery pulse wave
