Problems solved by technology

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,

Embodiment 1

[0020] Such as figure 1 As shown, an implantable electromagnetic pulsation artificial heart blood pump includes a pump body 1 and an electromagnetic drive device 2. The pump body 1 is implanted in the body during use. The pump body 1 is provided with a soft first diaphragm 11. The outer periphery of the first diaphragm 11 connects the inner chamber wall of the pump body 1 so that the inner chamber of the pump body 1 is divided into a first chamber and a second chamber 13 which are sealed and isolated from each other. The first chamber is an artificial heart chamber 12, preferably an artificial heart chamber. The volume of the heart chamber 12 is about 40ml. The artificial heart chamber 12 is provided with an inlet 121 and an outlet 122 for blood inhalation and discharge respectively, wherein the inlet 121 is provided with a first one-way valve for blood to flow into the artificial heart chamber 12 in one direction. The valve 131 and the outlet 122 are provided with a second on...

Embodiment 2

[0027] On the basis of embodiment 1 technical scheme, carry out following improvement:

[0028] Such as figure 2 As shown, the electromagnet 22 and the permanent magnet 23 in the electromagnetic drive device are all arranged in the second cavity of the pump body 1, the electromagnet 22 is fixedly arranged at the bottom of the pump body 1, and the permanent magnet 23 is directly connected to The bottom of the first diaphragm 11 can drive the first diaphragm 11 to reciprocate in the inner cavity of the pump body 1. The battery 24 and the control device 25 are located outside the pump body 1 and connected by wires. The electromagnet 22. During use, the pump body 1 is implanted in the body, the battery 24 is a small isotope nuclear battery 24 or a rechargeable lithium polymer battery 24, the battery 24 can be placed outside the body, or can be implanted subcutaneously, the control device 25 is placed outside the body, and the battery 24 and The electromagnet 22 and the control ...

Abstract

The invention relates to the technical field of medical instruments, in particular to an implantable electromagnetic pulsation type artificial heart blood pump which comprises a pump body and an electromagnetic driving device, the pump body is implanted into a body when used, and a soft first diaphragm is arranged in the pump body; the periphery of the first diaphragm is connected with the inner cavity wall of the pump body so as to divide the inner cavity of the pump body into a first cavity and a second cavity which are mutually sealed and isolated, the first cavity is an artificial heart cavity, and an inlet and an outlet for sucking and discharging blood are formed in the artificial heart cavity respectively; electromagnetic force serves as driving force to drive the first diaphragm to move in a reciprocating mode, then the blood discharging function of the artificial heart cavity is achieved, no other mechanical moving parts exist in the artificial heart cavity, blood cannot be damaged, no excessive mechanical moving parts occupy space, the space utilization rate of the pump body is very high, and the size can be very small and exquisite; and the device can be implanted under a thoracoscope, is simple to operate and is easily accepted by doctors and patients.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an implantable electromagnetic pulse type artificial heart blood pump. 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 surviv...
