Heart assisting blood pumping device

Abstract

The invention relates to a heart assisting blood pumping device, which comprises a chest cavity built-in component, an in-vitro driving component, a signal collection device, a control system and a power supply, wherein the chest cavity built-in component consists of a rigid case, an inner lining film, and a sealing cavity arranged between the rigid case and the inner lining film, wherein the sealing cavity is provided with an outer communication tube which is connected with the output end of the in-vitro driving component through a pressure regulation valve, the signal input end of the in-vitro driving component is connected with the signal output end of the control system, and the signal input end of the control system is connected with the signal collection device. When the heart chamber contracts, the in-vitro driving component pumps liquid into the sealed cavity for applying pressure on the heart chamber and helping the heart chamber to contract. When the heart chamber stretches,the liquid in the in-vivo sealed cavity is pumped out for releasing the pressure applied on the outer side of the heart chamber for being favorable for the stretching of the heart chamber and effectively solving the problem of powerless heart chamber contraction of congestive heart failure patients. The invention fully utilizes the contraction force of the heart chamber of the patients, so the required driving power is small, and in addition, the invention has no blood injury and is applicable to various congestive heart failure patients.

Description

technical field [0001] The invention relates to a heart artificial assisting device. Background technique [0002] With the advancement of science and technology, the manufacturing technology and clinical application technology of cardiac assist devices are constantly improving. Great progress has been made in research, especially in recent years, the left ventricular assist device produced in Germany represented by INCOR has greatly improved performance and reliability due to the use of high-performance axial flow blood pumps and magnetic suspension bearings. , has been initially used clinically, and a small amount has been introduced in my country in recent years for the clinical treatment of patients with advanced heart disease. However, the development of left ventricular assist devices needs to further solve problems such as the miniaturization of blood pumps and ejection efficiency, the damage of blood cells and coagulation, and the intelligence and reliability of contr...

AI Technical Summary

Problems solved by technology

However, the development of the left ventricular assist device needs to further solve the problems of miniaturization of the blood pump and ejection efficiency, damage of blood cells and coagulation, intelligence and reliability of the control device, etc.

In short, various artificial assistive devices focus on replacing or partially replacing the function of the heart, but there are many problems that need to be solved urgently. Although they have begun to be used in the human body, there is still a long way to go before they are widely used in a large area and for a long time. way to go
