Method and apparatus for detecting systema cariovasculare functional state

Abstract

The invention relates to a method and apparatus for detecting the condition of blood vessel system function, which is capable of non-invasive synchronously detecting the heart function, the carotid sclerosis, and the level of blood viscosity. The invention is characterized in that: a piezoresistance type sensor is positioned at neck for pressurizing; a heart sound signal piezoelectric sensor is positioned on the part of heart; a plurality of detecting electrodes for the electrocardiogram signals are arranged on the right hand wrist and lower parts of ankles; the cuffs of four limbs are arranged on upper arms and upper parts of ankles respectively; the inflation or deflation of cuffs is controlled by computer; the synchronous acquisition of the pulse signals of carotid, heart sound signals,electrocardiogram signals, pulse signals of carotids on four limbs by muilti-channel synchronous A / D die exchange module are converted; the converted signals are transmitted to a data processing module for data processing, and obtaining the heart function, the carotid sclerosis and the level of blood viscosity and other parameters.

Description

technical field [0001] The invention belongs to a non-invasive and non-destructive method and device for detecting the functional state of the cardiovascular system of a human body. Background technique [0002] Dysfunction of the blood circulation system can induce cardiovascular and cerebrovascular diseases, which are the "number one killer" of human health. In the initial stage of hypertension and arteriosclerosis, although there are no symptoms, the functional state of the blood circulation system has actually changed. With the transformation of the concept of prevention and treatment of cardiovascular diseases, people gradually realize that the occurrence and development of cardiovascular diseases must be viewed from a systematic point of view. The disease of a certain part or organ in the cardiovascular system may be the antecedent or consequence of the function and shape changes of other parts or organs. The various parts or organs of the cardiovascular system are in...

Problems solved by technology

However, the above-mentioned instruments only detect certain indicators of arteriosclerosis, and can only reflect one aspect of arterial function status, without synchronous detection of cardiac function status and blood viscosity level, so the clinical application value is small

At present, the equipment for testing blood viscosity level at home and abroad is a rheometer for measuring anticoagulant blood. Anticoagulants need to be added to prevent blood coagulation during measurement, and adding anticoagulants to blood will change the rheological properties of blood. The measured results are difficult to reflect the real rheological properties of blood in the human body, and the measurement process is complicated
