Abstract

The invention discloses a blood flowing detection device and method. The detection device comprises an inflation pressure binding belt, a detection host, as well as a temperature sensor and a humidity sensor which are connected with the detection host; and the detection host comprises a control button, a switching voltage-stabilized power supply circuit, a singlechip microcomputer central control-processing unit, a preamplifier, an A/D (analog-to-digital) conversion circuit, a display and a buzzer. The detection method comprises the following steps: releasing restriction after a blood flow atthe proximal end of a heart is restrained for a certain period of time; measuring changes of skin temperature and humidity on a position at a distal end of the heart, and comparing the changes with the standard parameters of people with a normal blood flowing condition; determining whether a testee has vascular endothelial dysfunction or not; and evaluating the severity of early symptoms of cardiovascular sclerosis and hemodynamics of the testee. The detection device has the advantages of simple structure, low cost and convenience for operation, causes no trauma or pain, and can be used for routine physical examination and community general examination.

Description

technical field [0001] The invention belongs to the technical field of blood flow condition detection, and in particular relates to a blood flow condition detection device and a detection method. Background technique [0002] At present, there are 160 million hypertensive patients in the country, and 3 million people die of cardiovascular and cerebrovascular diseases every year. The age of onset of cardiovascular and cerebrovascular diseases in big cities in my country has obviously moved forward. Patients with cerebral infarction, cerebral hemorrhage and myocardial infarction occur from time to time in their 30s, especially those born in the late 20th century and later. And the reduction of the amount of exercise creates conditions for the occurrence of vascular diseases. What is even more regrettable is that the survey shows that among the general population in my country, 90% of people do not know much about their blood pressure and the standard level for judging high blo...
