Electromagnetic cardiac pulse assisting device

Abstract

The invention relates to the technical field of medical instruments, in particular to an electromagnetic cardiac pulse assisting device. The electromagnetic cardiac pulse assisting device comprises an inner membrane, an outer membrane supporting body, two permanent magnets, electromagnets, a power source and a controller. The inner membrane covers the surface of the heart, and the outer membrane supporting body covers the outer side of the inner membrane. The two permanent magnets are fixed to the outer side of the inner membrane and correspond to the left ventricle and the right ventricle respectively. The two electromagnets are fixed to the inner side of the outer membrane supporting body and are opposite to the permanent magnets. The power source and the controller are used for supplying power to the electromagnets and adjusting the magnitude and the direction of current, so that the electromagnets can apply repulsive force or attractive force to the permanent magnets, and then the heart is driven to contract or relax. The device has the advantages of being capable of assisting the heart of the human body to beat, high in controllability, capable of improving the heart failure symptom and prolonging the service life of a patient, simple in structure, small and exquisite in size, capable of being implanted only through surgical operation, convenient to replace, low in manufacturing and using cost, long in service life and easy to accept by doctors and patients.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an electromagnetic cardiac pulsation assisting device. Background technique [0002] Heart failure (heart failure) referred to as heart failure refers to the failure of the venous blood to fully discharge the heart due to the dysfunction of the systolic function and / or diastolic function of the heart, resulting in blood stasis in the venous system and insufficient blood perfusion in the arterial system, resulting in Cardiac circulatory disorder syndrome, which is characterized by pulmonary congestion and vena cava congestion. Heart failure is not an independent disease, but the end stage of the development of heart disease. The vast majority of heart failures begin with left heart failure, that is, the first manifestation is pulmonary circulation congestion. The two-year survival rate of heart failure drug treatment is about 80%, and the five-year survival rate is only ...

AI Technical Summary

Problems solved by technology

[0003] At present, intra-aortic balloon counterpulsation is effective for patients with heart failure with low cardiac output and cardiogenic shock, but the equipment is bulky and cannot be carried, so it is not suitable and inconvenient for long-term use

Most of the foreign artificial heart research focuses on imitating the heart structure, and it is necessary to replace and remove the patient's heart. Due to insufficient energy supply, although artificial hearts are also used clinically, the risk of death of patients is high, and the life span is very short. Finally, because of the short life span , many complications, not accepted by patients, and difficult to promote

Heart transplantation is often difficult to be widely implemented due to lack of donors, large surgical trauma, high cost, and high immune rejection
