Double-plunger cylinder driving artificial heart pump

Abstract

The invention discloses a double-plunger cylinder driving artificial heart pump. An elastic haematodocha used for an artificial heart which is simple in structure and convenient in manufacturing is used, and two nipple-shaped bulges on the elastic haematodocha are used to replace a heart valve prosthesis which is extremely complex in structure, the inward nipple-shaped bulge and the outward nipple-shaped bulge being provided with holes on the center, thereby realizing one-way imbibition and one-way drainage. And the elastic haematodocha is driven by a double-plunger cylinder driving mechanism, so that the elastic haematodocha converts between a diastole operating state and a shrinkage operating state in turns, so as to realize processes of imbibitions and drainage in turns. The artificial heart pump can output impulse type blood flow similar to a natural heart, preventing technical directivity faults of a continuous blood pump, and preferably imitating operating process of a natural heart. The elastic haematodocha is made of an elastic scalable material, the internal of the elastic haematodocha is streamline, and would not damage cells in blood, and thrombus is not easy to form. The double-plunger cylinder driving artificial heart pump can preferably replace operation of a natural heart of a human or a vertebrate.

Description

technical field [0001] The invention relates to a double plunger cylinder 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 continuous pump that pumps blood without...

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 basica
