Intraoperative low temperature kidney protective bag and using method thereof

Abstract

The invention discloses an intraoperative low temperature kidney protective bag and a using method thereof. The intraoperative low temperature kidney protective bag comprises a protective bag body, acool storage interlayer, inner layer folds, a cold storage infusion port, a kidney placing inlet and a kidney gate opening. The cool storage interlayer is arranged in the protective bag body; the inner wall of the protective bag body is provided with the inner layer folds, and the inner layer folds enclose to form an inner cavity; the inner cavity is filled with kidney protection liquid; the upperpart of the protective bag body is provided with the kidney placing inlet, a first elastic rubber ring is arranged at the kidney placing inlet, the lower part of the protective bag body is provided with the kidney gate opening, and a second elastic rubber ring is arranged at the kidney gate opening; the first elastic rubber ring and the second elastic rubber are both provided with elastic retractable ropes. The intraoperative low temperature kidney protective bag can ensure cryopreservation effect of a kidney during a kidney transplant operation process, and effectively improve preservation quality of the kidney. The intraoperative low temperature kidney protective bag is an easy-to-operate special refrigerated storage bag for transplanted kidney, and can be specially used in a kidney transplant operation.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a low-temperature kidney protection bag for intraoperative use and a usage method thereof. Background technique [0002] In clinical kidney transplantation, in the process of transplanting the kidney to the recipient, it takes a while for the anastomosis of the renal artery, renal vein, and ureter to the bladder. At present, it takes about 30-60 minutes for relatively mature kidney transplantation centers to perform vascular anastomosis . In the process of vascular anastomosis, the ischemic time and storage conditions of the donor kidney have an important impact on the recovery of renal function after the kidney donation. The current main method is mainly to adopt low temperature preservation, to store in kidney preservation solution or to place ice-containing gloves with holes on the donor kidney. During the operation, the donor kidney was turned several ti...

AI Technical Summary

Problems solved by technology

During the operation, the donor kidney was turned over many times to assist the vascular anastomosis, and the repeated repositioning of ice gloves was not only inconvenient but also affected the effect of hypothermia

[0003] In the traditional process of protecting the kidney during kidney transplantation, it is impossible to ensure that the kidney is in a uniform low temperature state, and it cannot achieve a good protective effect on the kidney, which affects the recovery of patients after surgery.

[0004] The patent No. CN205848496 is "a low-temperature storage bag for kidney transplantation". The main problems of this storage bag are: (1) The kidney accommodation chamber is fixed and cannot be automatically stretched and adjusted according to the size of the kidney. It is especially inconvenient for children or young children; (2) the preservation bag only plays the function of preserving the kidney, and cannot realize the protection during the kidney transplantation operation, and the kidney protection fluid is not filled in the kidney accommodation chamber; (3) the set The input port of the ice-water mixture and the output port of the ice-water mixture are removed, which makes the operation extremely cumbersome and affects the operation of the operator
