Hypertension blood circulation simulation device

Abstract

The invention discloses a hypertension blood circulation simulation device which comprises a liquid storage tank, a constant pressure tank, a flow generator, a pre-pressing device, a flow sensor, a pressure sensor, a plurality of throttle valves and a simulation blood vessel, the flow sensor comprises a front flow sensor and a rear flow sensor, and the liquid storage tank comprises a one-way waterpump and working liquid; the liquid storage tank is sequentially connected with a constant-pressure tank, a flow generator, a pre-pressing device, a front flow sensor, a pressure sensor, a pluralityof throttle valves and a rear flow sensor through simulated blood vessels. The pre-pressing device is used for applying pressure to the interior of the simulated blood vessel in a hydraulic pressure increasing mode. The pressure drop generated when the working fluid flows is calculated according to the pre-pressing device and the pressure sensor; the device can be used for further research after the flow sensors are arranged in front of and behind the device, a speed relation is obtained through analysis of the front flow sensor and the rear flow sensor, fluid pressure is adjusted through thepre-pressing device and the throttle valve, fluid speed is adjusted through the flow generator, and relevant parameters of hypertension patients are consistent.

Description

Technical field [0001] The invention relates to the field of medical equipment, and more specifically, to a hypertension blood circulation simulation device. Background technique [0002] Hypertension is mainly characterized by increased systemic arterial blood pressure (systolic and / or diastolic blood pressure) (systolic blood pressure ≥140 mmHg, diastolic blood pressure ≥90 mmHg), and may be accompanied by the functions of the heart, brain, and kidneys. Or a clinical syndrome of organic damage. For hypertensive patients with extracorporeal blood circulation, both medical and fluid mechanics need to be studied, and the research needs the assistance of hypertension blood circulation simulation devices. However, most of the current researches are in the body state, and it is extremely difficult to conduct in-vivo research. Due to various factors, it is difficult to carry out research on the blood circulation of hypertensive patients. For other extracorporeal circulation simulatio...

Problems solved by technology

For the extracorporeal blood circulation of hypertensive patients, both medicine and fluid mechanics need to do relevant research, and the research needs the assistance of a hypertensive blood circulation simulation device, but most of the research nowadays is in vivo, and it is extremely difficult to conduct in vivo research Large and limited by various factors, it is difficult to carry out blood circulation research on hypertensive patients; and for other existing extracorporeal circulation simulation devices, there is no blood circulation simulation device system for hypertensive patients. The patient's systemic blood pressure increases, so it is necessary to design the simulation device according to this characteristic, which is difficult
