Embodiment Construction

[0035] The embodiment provides a kind of total artificial heart device, such as figure 1 As shown, it includes a simulated heart, that is, a built-in part 1 of the chest cavity, an external drive part 4 , a pressure regulating valve 3 and an external communication tube 2 . For the structure of the built-in part 1 of the chest cavity, see figure 2 and image 3 : It is mainly composed of simulated atrium, simulated ventricle, atrial septum, ventricle septum, atrioventricular septum, 4 one-way valves, 2 output pressure adjustment rings, 4 drainage tubes, etc. The hard shell 10 of the simulated atrium 6 and the simulated ventricle is made of hard material, and the soft inner bag 9 of simulated ventricle is made of elastic soft material. The soft liner 9 is divided into a disconnected simulated left ventricle 12 and a simulated right ventricle 13 by a ventricle partition 11; the simulated atrium 6 is divided into a disconnected simulated left atrium 15 and a simulated right atri...

Abstract

The invention provides a total artificial heart device, comprising a thoracic cavity built-in part, an in-vitro drive part connected with the thoracic cavity built-in drive part and a control system with a power supply. The thoracic cavity built-in part structure simulates a human heart and is divided into four separated regions, the upper half part is a simulated atrium, and is made of hard materials, and the lower half part is composed of a soft inner container and a hard shell which form a sealing hollow cavity; the hard shell is provided with an external communication tube which is connected with a compressed package in the in-vitro drive part through a pressure regulating valve, so as to lead the sealing hollow cavity in vivo and the compressed package in the in-vitro drive part to form a communicating vessel; when the in-vitro drive part pumps liquid into the sealing hollow cavity, a pressure is applied to the soft inner container to pump out blood in the soft inner container; and when the liquid in the sealing hollow cavity is pumped out, the pressure applied on the outer side of the soft inner container is released, the inner container restores to the original condition and a negative pressure is generated so that the blood in the simulated atrium flows into a simulated ventricle. The invention has the advantages that the device has no damage on the blood and can replace the heart to work.

Description

technical field [0001] The invention relates to a total artificial heart device. Background technique [0002] With the advancement of science and technology, the manufacturing technology and clinical application technology of artificial heart are constantly improving, especially in the United States, Germany and other developed countries, in the research of left ventricular assist device, right ventricular assist device, total artificial heart and other heart assist devices Great progress has been made in all of China. The total artificial heart, as an indispensable medical device for maintaining cardiac function during cardiac surgery, has been successfully used clinically. , prone to coagulation, can only be used for a short time during surgery, and cannot be used for a long time as a substitute for the patient's heart. However, all kinds of artificial heart assist devices can only partially replace the functions of the heart, such as making ventricular assist devices to...
