Abstract

The invention relates to a hemolysis-free continuous isolated heart transfer device which comprises a box body and a box cover, a circulating liquid cavity and a heart placing cover are arranged in the box body, the heart placing cover is of a solid net-shaped structure similar to the shape of the heart, two blood vessel penetrating-out connectors are arranged on the heart placing cover, a displacement pump circulating device is arranged in the circulating liquid cavity, a liquid inlet pipe and a liquid outlet pipe are connected to the displacement pump circulating device, the liquid inlet pipe and the liquid outlet pipe are aligned to the two blood vessel penetrating-out connectors respectively, and elastic ribbons are arranged on the blood vessel penetrating-out connectors. In the heart transfer process, the heart can be kept in a circulating state, meanwhile, blood cell damage is effectively reduced, damage to the heart caused by in-vitro transfer is reduced, and the heart transplantation success rate is increased.

Description

Technical field: [0001] The invention relates to the technical field of cardiac surgery medical instruments, in particular to a non-hemolysis beating isolated heart transfer device. Background technique: [0002] Heart transplantation is a common cardiac surgery procedure. However, due to the lack of heart donors, especially the difficulty of long-term preservation and transportation of donor hearts, tens of thousands of patients lose their lives every year while waiting for heart transplantation. At present, in the clinical practice of heart transplantation, there are many ways to use heart preservation solution to preserve the donor heart by low temperature immersion. The donor heart is soaked in the heart preservation solution at 4°C. During the preservation period, the donor heart is in a low temperature cold ischemia state. The safe and reliable storage time limit can reach 6 hours; however, there are often uncertain factors and complex environments in the acquisition ...
