Anticoagulation-free heart auxiliary contraction device

Abstract

The invention relates to an anticoagulation-free heart auxiliary contraction device. The anticoagulation-free heart auxiliary contraction device comprises a central processing unit (1), and a power supply (4), an electrocardiogram monitoring module (7) and a flexible driving shell (5) which are connected with the central processing unit (1); the flexible driving shell (5) is used for wrapping the outer side of a heart (8) and comprises a plurality of contraction bags (51) which are arranged in a tiled manner; a liquid medium (52) is hermetically stored in each contraction bag (51), and an electrode (6) connected with the central processing unit (1) is arranged on the outer surface of each contraction bag (51); and each electrode (6) comprises a negative electrode (61) and a positive electrode (62), and the negative electrode (61) and the positive electrode (62) are arranged on two opposite sides of the corresponding contraction bag (51) respectively. Compared with the prior art, the device is high in flexibility, simple in structure, small in size, convenient to install, good in safety and capable of effectively driving blood to flow and improving the overall pulsation volume of the heart.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anticoagulant-free heart assist systole device. Background technique [0002] Heart failure refers to the failure of the systolic function or diastolic function of the heart to fully discharge the venous return blood to the heart, resulting in blood stasis in the venous system and insufficient blood perfusion in the arterial system, thereby causing cardiac circulation disorder syndrome. For pulmonary congestion, vena cava congestion. Due to the non-renewable nature of myocardial tissue in the heart, patients with advanced heart failure cannot live normally or even lose their lives. This problem can only be solved by heart transplantation, but there is a shortage of heart transplant donors. [0003] The current solution to this problem is usually to attach a flexible contractile material to the surface of the heart tissue, and assist the heart to contract by driving th...

Problems solved by technology

[0005] In this patent, the heart is driven by a pressurized sac, and the shape of the pressurized sac cannot be adjusted to adapt to the shape of the heart. At the same time, the pressure applied by the pressurized sac to each position of the heart is the same, which cannot be adjusted locally, resulting in poor systolic effect and possible damage to the heart;

[0006] This patent requires the use of delivery pumps and fluid sources, which are bulky and difficult to install. At the same time, it is very easy to cause infection, abnormal coagulation function and thrombus. The environmental conditions required for the use of this device are harsh.
