Electromagnetic-permanent magnetism bidirectional driving type artificial heart pump

Abstract

The invention discloses an electromagnetic-permanent magnetism bidirectional driving type artificial heart pump employing artificial heart elastic blood sacs with simple structure and easy making; two nipple-shape bosses facing inwards and outwards are arranged on the elastic blood sac, and respectively provided with a central hole, thus replacing artificial heart valves of complex structures, and realizing unidirectional imbibition and unidirectional apocenosis; the artificial heart elastic blood sacs are driven by an electromagnetic-permanent magnetism bidirectional driving mechanism having only one armature, so the two elastic blood sacs are alternatively switch between a diastole work state and a contraction work state, thus alternatively realizing imbibition and apocenosis process, outputting pulse type blood flow like a natural heart, preventing technical directional errors of a continuous blood pump, and well simulating the work process of the natural heart; in addition, the elastic blood sacs are made of elastic telescopic materials, streamline form is realized inside, so cells in the blood cannot be damaged, and thromboses are hard to form, thus well replacing the work of a natural heart of a human being or vertebrate.

Description

technical field [0001] The invention relates to an electromagnetic-permanent magnet bidirectional drive type 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 pum...

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
