Description
Technical Field
The invention belongs to the technical field of external counterpulsation equipment, and particularly relates to a bandage contraction type external counterpulsation device.
Background
Counterpulsation is an auxiliary circulation method for reducing the systolic blood pressure and increasing the diastolic blood pressure in the aorta in a mechanical way so as to assist the heart to do work, improve blood circulation and increase blood perfusion of organs such as heart, brain, kidney and the like. The counterpulsation can increase the blood supply of coronary artery by increasing the diastolic pressure of aorta, rescue ischemic myocardium and improve the blood pumping function of heart. Commonly used counterpulsation methods include intra-aortic balloon counterpulsation and extra-corporeal counterpulsation.
The external counterpulsation is a method for non-invasively pressing the lower half body in vitro, relieves and eliminates the symptoms of angina pectoris, improves the anoxic and ischemic states of important organs of the body, and is medical equipment for preventing and treating cardiovascular and cerebrovascular diseases. The traditional external counterpulsation device inflates and pressurizes air bags at the diastole of the heart by the air bags wrapped on the limbs and the hip, so that the blood in the artery and the vein of the limbs returns to the heart, the diastolic pressure is obviously increased, the blood perfusion of important organs such as the heart, the brain and the like is improved, and the afterload of the heart is reduced; the air bag can exhaust air rapidly in the systole, the pressure is relieved, the systolic pressure in the aorta is reduced, the resistance in the cardiac ejection period is relieved to the maximum extent, and the blood flows to the far end in an accelerated way, thereby achieving the counterpulsation effect.
However, the conventional air bag inflation and pressurization method is not accurate enough in controlling the degree of the pressing force, and has slow speed response. Specifically, the process of inflating and pressurizing the airbag is a compression transfer process of gas, that is, the movement of the gas in the gas path is a pressure equalization process performed under the condition of pressure difference, and the process has a slow response speed relative to contact type mechanical extrusion; meanwhile, the gas circuit pressure change is nonlinear, so that the control is more complicated.
