Embodiment Construction

[0025] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0026] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening ele...

Abstract

The invention relates to an isolated organ perfusion apparatus, which comprises a shell, a perfusion assembly, a heat exchange assembly and a controller, wherein the perfusion assembly comprises a first power pump, the output end of the first power pump is used for connecting to the power pump head of a container so as to provide power for perfusing a perfusion fluid to an isolated organ, the heatexchange assembly comprises a constant temperature box and a second power pump, the constant temperature box is used for accommodating a heat exchange liquid, a heating member for heating the heat exchange liquid is arranged inside the constant temperature box, the constant temperature box is communicated to the container through a pipeline to form a circulation heat exchange pipeline for carrying out heat exchange on the perfusion fluid, the second power pump is used for providing circulation flowing power to the heat exchange liquid, and the first power pump, the second power pump and the heating member are respectively and electrically connected to the controller. According to the present invention, the isolated organ perfusion apparatus continuously perfuses a perfusion fluid to an isolated organ to achieve the long-time storage of the isolated organ in a normal temperature environment so as to improve the success rate of the transplant operation.

Description

technical field [0001] The invention relates to the technical field of auxiliary medical devices, in particular to an isolated organ perfusion device. Background technique [0002] Lung transplantation is the only effective treatment for end-stage lung disease. At present, the main obstacles restricting the development of lung transplantation are the shortage of donor lungs, high mortality rate of recipients, early postoperative primary vegetative dysfunction, and chronic rejection. The success or failure of the donor lung is directly related to the success or failure of the transplant operation. [0003] The traditional method of preservation of isolated organs is low-temperature static preservation. Low temperature static preservation method reduces the energy consumption of organs by low temperature, thereby prolonging the preservation time of organs, which has the advantages of simplicity, safety, and low price. [0004] However, long-term low temperature environment ...
