Abstract

The invention relates to a transplant cold protection bag which is formed by three layers of plastic composite films. A transplanted organ placement bag, a refrigerating bag and a heat insulation bag which are formed by middle films, are mutually closed and are provided with inner films are arranged in a wear-resistant plastic bag of an outer film; the transplant cold protection bag can be used for storing organ preservation solution, transplanted organs, a cool storage material and a heat insulation material which have temperatures of 0 to 4 DEG C; one end of the transplanted organ placement bag, together with the wear-resistant plastic bag, is provided with a transplanted organ taking and storing port formed by two magnets and a sealing material together; and the other end of the transplanted organ placement bag, together with the wear-resistant plastic bag, is provided with a liquid replacement tube with a blockage cap. The transplant cold protection bag disclosed by the invention ensures a low temperature of 0 to 4 DEG C, which is required by transplants in an operation and enables the transplants to have no warm ischemia time; the body temperature of a receptor is prevented from being reduced due to conduction of brine ice gauze and complications are reduced; and the transplants are convenient to move and a touch technology is not adopted. The transplant cold protection bag greatly improves the survival rate of postoperative organs and has important clinical significance and application prospect for storage of the transplants in the organ transplantation and vascular reconstruction process.

Description

technical field

[0001] The invention relates to a cooling protection device for a transplanted organ, in particular to a graft cold protection bag used in organ transplantation operations. Background technique

[0002] At present, when performing vascular anastomosis in organ transplantation, the transplanted kidney is protected with ice-cold saline gauze at 0-4°C, and placed in the recipient's body to facilitate the transplant operation. During the operation, in order to prevent the body temperature of the recipient from rising to the temperature of the iced saline gauze, which in turn raises the transplanted organ inside the iced saline gauze, causing warm ischemia in the transplanted organ, which is detrimental to the postoperative functional recovery of the transplanted organ, and requires continuous Changing the iced saline gauze in the body or intermittently replenishing the gauze with iced saline, these two actions will increase the operation time, increase the pain o...
