Preservation device for heart transplantation and method of use thereof

Abstract

The invention discloses a preservation device for heart transplantation and a method of use thereof, relating to the technical field of heart transplantation, comprising a protection box, the top of the protection box is rotatably connected with a cover plate, and the top of the protection box is located below the cover plate A storage chamber is provided. The storage device for heart transplantation is equipped with an air bag, a connecting piece and a moving column. When the operator closes the cover, he pushes the moving column to move down, so that the rack drives the transmission gear to rotate, thereby driving the piston through the transmission mechanism. Move to the direction of the connecting pipe, so that the piston pushes the gas inside the storage cylinder into the airbag through the connecting pipe, so that the airbag expands, so that the airbag pushes the connecting piece to move towards the direction of the storage box, so that the connecting piece pushes the pressure plate to limit the storage box, so that this The device can not only limit the position of the storage box, but when the device is hit, the air bag buffers the force received by the storage box, so that the heart tissue inside the storage box will not be damaged.

Description

technical field [0001] The invention relates to the technical field of heart transplantation, in particular to a preservation device for heart transplantation and a use method thereof. Background technique [0002] With the development of medical technology and the use of new anti-rejection immunosuppressants, heart transplantation has become an effective means of treating end-stage heart disease. Before the heart transplant operation, the preservation effect of the donor heart directly affects the success rate of the heart transplant operation. [0003] The patent application number CN03117851.0 discloses a continuous perfusion heart preservation device, which includes a heart and a preservation solution storage container, a membrane lung, a perfusion pump, a perfusion tube located in the heart and a preservation solution storage container, a liquid inlet tube, and a liquid outlet tube , Sampling tube. One end of the liquid inlet pipe is connected with the heart and the p...
