Totally-artificial heart in built-in mode

Abstract

The invention provides a totally-artificial heart in built-in mode. The totally-artificial heart comprises a fixation unit, an energy control unit, power units, and flow direction control units. The power units are flexible peristaltic pumps driven by alternating voltages. The fixation unit having a rigid structure is used for fixing the energy control unit, all power units, and all flow direction control units. Flow direction control unit doors arranged inside the flow direction control units are used for controlling flowing directions of fluid. The energy control unit outputs alternating voltages with variable frequencies and waveforms to control the power units, thereby meeting various requirements of human bodies. According to the totally-artificial heart in built-in mode, the totally-artificial heart can be used as an auxiliary artificial heart based on simple modification. With the driving thin-film material, the complicated mechanical structure is simplified and the energy consumption of the artificial heart is reduced substantially; the totally-artificial heart can be arranged in a built-in mode, so that the usage and maintenance costs can be lowered. Meanwhile, noises during working of the artificial heart can be reduced substantially, so that the comfort of the artificial heat can be improved. Besides, on the basis of the unique structural design, a certain adjuvant treatment effect for some traditional cardiovascular diseases is realized.

Description

technical field [0001] The invention relates to the field of biomedical engineering, in particular to a built-in total artificial heart made of a capsule-shaped dielectric elastomer film driven by an alternating voltage. Background technique [0002] Heart disease is the leading cause of human death. The treatment of heart disease is very difficult, and currently it is difficult to have a cure for heart disease other than heart transplantation. When the human heart partially or completely loses its function due to disease damage and cannot maintain the normal blood 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 and promote blood circulation. The device is an artificial heart. Those that partially replace the functions of the human heart are called auxiliary artificial hearts, and those that completely replace the functions of the human heart...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the traditional artificial heart with complex mechanical structure, high volume occupation, high energy consumption and high noise, the invention uses intelligent soft materials as the driver and the artificial heart itself, which greatly simplifies the structure, reduces energy consumption, noise and occupied volume

Due to the removal of complex mechanical structures (such as motors, gear transmission mechanisms, springs, hinges, screws, bolts, etc.), the biocompatibility problem of traditional artificial hearts is solved
