Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and more specifically, to a blood vessel protection frame and a heart implant device. Background Art

[0002] Heart failure, also known as HF, refers to the inability of the heart to pump out enough blood to maintain systemic blood circulation. For patients with heart failure, there are three treatment options: conservative drug therapy, heart transplantation, and heart implant devices. The effect of drug therapy is poor, and heart transplant donors are limited, so heart implant devices have become a recognized and more effective treatment for various types of end-stage heart failure. Heart implant devices require an artificial blood vessel to connect the blood pump outlet and the aorta. Due to the complex environment in the chest cavity, a vascular protection frame needs to be installed to protect the artificial blood vessel to prevent the artificial blood vessel from being squeezed and deformed, resulting in problems such as decreased blood pump flow and increased power. Studies have found that foreign matter will grow in the gap between the artificial blood vessel and the vascular protection frame. The proliferated foreign matter will squeeze the artificial blood vessel, resulting in problems such as decreased blood pump flow and increased power.

[0003] Therefore, how to prevent the proliferating foreign matter from squeezing the artificial blood vessel and reduce the occurrence of problems such as the decrease in blood pump flow and the increase in power has become a technical problem that needs to be solved urgently by those skilled in the art.

[0038] It should be noted that in the cardiac implant device, the blood pump 500 is used to drive the blood in the ventricle to flow into the artery through the artificial blood vessel 400. The first end of the artificial blood vessel 400 is sleeved on the blood pump 500, and the second end is connected to the artery. The clamp 100 is set at the first end of the artificial blood vessel 400 to fix the artificial blood vessel 400 on the blood pump 500. One end of the protective cover 200 is connected to the clamp 100, which can be connected by a snap connection, or by a connection, or by an adhesive, which is not specifically limited here. The other end of the protective cover 200 extends in the direction of the artificial blood vessel 400 and is sleeved on the outside of the artificial blood vessel 400 to protect the artificial blood vessel 400 and prevent the artificial blood vessel 400 from being squeezed and deformed.
