External counterpulsation pressurization system

Abstract

The embodiment of the invention provides an external counterpulsation pressurization system. The external counterpulsation pressurization system comprises a control panel, a computer control center, an air source pressure controller, an air source device, a counterpulsation sequential electromagnetic valve, an air bag device and a sensor module. The control panel comprises a display module and a control module, the display module receives the air bag pressure information sent by the sensor module, and the control module sends a pressurizing requirement set by a user to the computer control center. The computer control center is connected with the air source pressure controller and the counterpulsation sequential solenoid valve, on one hand, air conveyed to an air bag by the air source device is controlled, and on the other hand, the inflation or deflation state of the air bag is controlled through the counterpulsation sequential solenoid valve, so that the pressure value of the air bagis increased to the gradient pressure value at most; and the gradient pressure value is gradually increased every preset time according to a preset rule and stops increasing after reaching a preset final pressure value, and the maximum pressure of the air bag in each counterpulsation period is kept at the final pressure value in the remaining treatment time. The sensor module collects the pressure value of the air bag device and transmits the pressure value to the control panel. According to the system, the pressure of the air bag can be slowly and gradually increased to the set treatment pressure in a multi-step mode according to different physical conditions and tolerance differences of patients, a gradually adapting process is provided for the patients, and the experience and treatmentcompliance of the patients are optimized.

Description

【Technical field】 [0001] The invention relates to the field of medical equipment, in particular to an external counterpulsation pressurization system. 【Background technique】 [0002] External counterpulsation is a safe and effective non-invasive mechanically assisted circulation method. Its working principle is: the lower limbs and buttocks of the human body are wrapped with special airbag sleeves. In the early diastole, the airbags of each section are inflated and pressurized sequentially from far to near, driving the blood of the lower limbs and buttocks to flow back to the aorta, so as to Increase the diastolic pressure and blood volume of the aorta, thereby improving the blood supply to important organs such as the heart, brain, kidneys, and five sense organs; before the systole period, all the air bags are quickly and synchronously exhausted, the blood vessels of the compressed limbs suddenly open, and the peripheral resistance sharply Descending, the blood ejected fro...

AI Technical Summary

Problems solved by technology

However, the existing external counterpulsation device, after starting the gas source to start the treatment procedure, quickly increases the pressure in the airbag to the required treatment pressure according to the same rapid pressurization method, ignoring the physical condition and tolerance difference of different patients , seriously affecting patient experience and treatment compliance
