a blood flow diverter

Abstract

The invention discloses an arterial-venous blood flow divider capable of controlling blood pressure fluctuation quickly and effectively in real time. The blood flow divider can divide the arterial blood flow to the vein when the blood pressure rises so as to prevent further rise of the blood pressure and achieve an aim of controlling the blood pressure fluctuation. The blood flow divider comprises a tubular component and a flow control component, wherein the flow control component is arranged in the tubular component; a through hole along the axial direction of the tubular component is formed in the flow control component; the size of the through hole changes in real time along with the magnitude of pressure, and the blood flow rate changes in real time along with the size change of the through hole; if the through hole becomes larger, the blood flow rate increases along; and if the through hole becomes smaller, the blood flow rate decreases along. Furthermore, the through hole has an open threshold; when the blood pressure is lower than or equal to the threshold, the through hole is kept in a minimum state; and when the blood pressure is higher than the threshold, the through hole becomes larger to be opened.

Description

technical field [0001] The invention relates to a blood flow shunt, in particular to a blood flow shunt for controlling blood pressure fluctuations. Background technique [0002] Hypertension is a common disease that seriously affects social health. In my country alone, there are about 330 million patients. Death from cardiovascular and cerebrovascular diseases is the number one cause of death in my country, and hypertension accounts for about 64.0% of all deaths from cardiovascular and cerebrovascular diseases. The blood pressure of the human body is not static, and there are fluctuations (or variability). Both strenuous activity and mood swings increase blood pressure levels and blood pressure fluctuations, while rest, sleep, and digestion significantly decrease them. Blood pressure fluctuations increase with age. Changes in temperature, blood volume, diet, irrational drug use and other factors also have an impact on blood pressure fluctuations. A large number of studi...

AI Technical Summary

Problems solved by technology

However, drug control has the following disadvantages: ①Slow onset, most drugs take more than one hour to take effect, and the fastest takes tens of minutes, which is obviously slow for urgent control and sudden increase of blood pressure; ②Cannot achieve real-time control

Medication control depends on blood pressure detection. Patients can adjust their medications only when they detect blood pressure fluctuations. However, it is obviously impossible and inconvenient to monitor blood pressure every moment; ③The metabolism of hypertension drugs is slow, and the dosage is difficult to control

The metabolism of high blood pressure drugs takes several to tens of hours. If the patient causes high blood pressure factors to be relieved, these drugs have not been metabolized, which may cause blood pressure to be too low

Different patients have different sensitivity and tolerance, and sometimes it is difficult to grasp the appropriate dosage for patients
