Artificial heart

Abstract

The invention relates to an artificial heart. The artificial heart comprises a whole-heart balloon positive pulse system and a myocardium regeneration induction system. The whole-heart balloon positive pulse system comprises a ventricle jacket, balloons and a power system, wherein the ventricle jacket wraps the ventricles, the balloons are arranged between the ventricles and the ventricle jacket, and the balloons are connected with the power system through gas catheters; in ventricular systole, the power system inflates the balloons, and in ventricular diastole, the power system deflates the balloons. The myocardium regeneration induction system comprises laser fibers and a laser device, wherein one end of each laser fiber is connected with the laser device, the other ends of the laser fibers are positioned on the outer surfaces of the ventricles, the laser device emits lasers according to preset parameters, and the lasers irradiate the outer surfaces of the ventricles through the laser fibers to induce myocardial cell regeneration. According to the artificial heart, myocardial cell regeneration can be induced, so that the myocardial structure is improved, the influence of artificial materials on the blood system is avoided, and the systolic and diastolic function of the heart is recovered; the artificial heart is high in operability and wide in application range; the artificial heart also can serve as a permanent auxiliary device of the heart.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an artificial heart. Background technique [0002] Heart failure (hereinafter referred to as heart failure) is the final destination of most cardiovascular diseases, and it is a common, high medical expenditure and potentially fatal disease. China's 2011 cardiovascular disease report pointed out that there are currently about 4.2 million heart failure patients in my country; in developed countries, about 2% of adults suffer from heart failure, and those over the age of 65 increase to 6- 10%. And that number is increasing as the global population ages. In the past 30 years, despite many advances in the diagnosis and treatment of heart failure, the mortality rate of heart failure remains high. The risk of death was 35% in the first year after heart failure diagnosis and decreased to 10% each year thereafter. Even with the best treatment, the annual mortality rate from heart failur...

AI Technical Summary

Problems solved by technology

However, left ventricular assist devices still have significant limitations.

First, the device can only partially improve the function of the failing heart, causing irreversible damage to the myocardium and heart valves

Secondly, this method has a series of contraindications and complicated process, so the practical application range is very limited

Third, this method can only temporarily replace the left heart pumping blood, and its service life is limited

Finally, the current ventricular assist device needs to be in direct contact with blood, and a series of fatal complications such as bleeding, thrombus, hemolysis, infection, and immune response will inevitably occur
