Human body blood pressure limiter

Abstract

The invention discloses a human body blood pressure limiter which comprises a valve body and a valve core which are arranged in a human body; the area of the front end of the valve core is A; a spring with the elastic force of F is arranged between the upper end of the valve core and that of a valve cavity; a blood inlet is formed on one side of the valve cavity, the inner port of the blood inlet is communicated with the valve cavity, and the outer port is communicated with arterial vessels of the human body through artificial blood vessels; a valve-in pipeline is arranged at the blood inlet and is communicated with the bottom of the valve cavity; a blood outlet is formed on the other side of the valve cavity and is led out of the human body or is communicated with the vein vessels of the human body through the artificial blood vessels; the dangerous critical blood pressure of the human body is set as P; A and F meet the condition that F equals to P multiplied by A; when the blood pressure of the human body is higher than P, the valve core moves upwards, a part of blood flows out of the human body or flows into the vein vessels of the human body from the arterial vessels of the human body through the blood inlet and outlet; and when the blood pressure of the human body is lower than P, the valve core moves downwards so as to block the blood inlet and the blood outlet. The human body blood pressure limiter can limit rising of the blood pressure automatically under the emergent situation that the blood pressure of hypertension personnel rises sharply and seriously threatens lives.

Description

technical field [0001] The invention relates to a medical device, in particular to a human body blood pressure limiter. Background technique [0002] At present, there are more and more people with high blood pressure, which is easy to cause blood vessel bleeding; once the blood pressure rises sharply due to emotional fluctuations or external stimuli, in such occasional cases, it is useless to rely on traditional drugs to lower blood pressure, and the sudden rise in blood pressure will cause Lead to cerebral blood vessel rupture, rupture of hemangioma, stroke, etc., which are seriously life-threatening. Contents of the invention [0003] The purpose of the present invention is to provide a human blood pressure limiter with simple structure and low cost, which can automatically limit the rise of blood pressure in the occasional situation where the blood pressure of a hypertensive person suddenly rises and seriously endangers life. [0004] To achieve the above object, the ...
