Elastic haematodocha for artificial heart and air-bag-driven artificial heart pump

Abstract

The invention discloses an elastic haematodocha for artificial heart and an air-bag-driven artificial heart pump. The air-bag-driven artificial heart pump adopts an elastic haematodocha for artificial heart which is simple in structure and convenient to make. An inward nipple-like protrusion having a hole in the center and an outward nipple-like protrusion having a hole in the center on the elastic haematodocha substrate an artificial heart valve prosthesis being extreme complex in structure, so that unidirectional imbibition and unidirectional apocenosis can be achieved, an air bag driving mechanism only having one tracheae inserted in the body is used for driving the elastic haematodocha to work, so that the elastic haematodocha can alternate between a diastole work state and a contraction work state, so as to alternate imbibition and apocenosis, to output a pulse blood flow like that output from a natural heart, so that a work process of the natural heart can be well simulated. At the same time, the elastic haematodocha is made from elastic telescopic material, the inner of the elastic haematodocha is a streamline structure which does not destroy cells in the blood, and thrombus will not be generated, so the elastic haematodocha for the artificial heart and the air-bag-driven artificial heart pump can substrate humans' or vertebrate natural hearts to work.

Description

technical field [0001] The invention relates to an elastic blood bag for an artificial heart and an air bag-driven artificial heart pump. Background technique [0002] Heart disease is the second leading killer of human death. When the human heart loses part or all of its function due to disease and injury and cannot maintain the normal circulation of the whole body, a mechanical device made of artificial materials can be transplanted to temporarily or permanently replace the heart function partially or completely to promote blood circulation, so that the device is Artificial heart, which is also an effective means to solve end-stage heart disease in addition to heart transplantation, has largely solved the problem that heart transplantation cannot be performed in time due to insufficient donors. [0003] At present, the artificial heart mainly uses two blood pumps with different principles, namely, the pulse volume pump based on the artificial heart valve, and the continuo...

Problems solved by technology

However, artificial heart valves are extremely complex, expensive to manufacture, and prone to blood clots, known as thrombi, forming in moving parts

[0005] For example, Chinese Patent Publication No. 1093005, named "integrated capsule artificial heart-lung pump", in this kind of artificial heart-lung pump, the blood storage bag is installed in the pump This structure is easy to form thrombus in the human body, and the artificial heart valve is not easy to manufacture

Chinese Patent No. 99126700.1, titled "Air-Electric Integrated Blood Pump, Air-Electric Integral Artificial Heart" provides a gas-electric integrated artificial heart. However, its internal structure is complicated, and it is basically impossible to manufacture, and high implementation cost

For example, Chinese Patent Publication No. 102019002A, titled "An Implantable Hollow Miniature Axial Blood Pump", and Chinese Patent Publication No. 10237598, titled "Compact Axial Flow Magnetic Levitation Artificial Heart Pump" Among them, both of them use an axial flow pump. Although it can damage the cells in the blood less than the gear pump and the vane pump, the high-speed operation of its components still destroys the cells in the blood. , and since the axial flow pump is a continuous pump, it cannot simulate the working process of the natural heart, so it can be said that it is a selective error in the direction of technology
