Description

Technical Field

[0001] The utility model relates to the field of medical devices, in particular to a kidney protection bag. Background Art

[0002] In clinical kidney transplantation, during the process of transplanting the kidney into the recipient, it takes a while for the renal artery, renal vein, and ureter to anastomose with the bladder. At present, the time for vascular anastomosis in more mature kidney transplant centers is about 30-60 minutes. During the vascular anastomosis, the donor kidney must be in an ischemic and non-cryogenic state, which will have an important impact on the recovery of the donor kidney function after surgery. The ischemic time and storage conditions of the donor kidney have an important impact on the recovery of renal function after the donor kidney surgery. The current method is to place a glove with ice holes on the donor kidney and spray ice water on the donor kidney intermittently to keep the donor kidney in a low-temperature state. However, the donor kidney needs to be turned over many times during the operation to assist in vascular anastomosis. Repeatedly re-placing the ice gloves is not only inconvenient but also affects the low-temperature effect; moreover, the time of intermittent spraying of ice water during the operation is affected by the progress of the operation, and the interval time is unstable, which also affects the low-temperature effect of the donor kidney. Turning the donor kidney many times during the operation to assist in vascular anastomosis and repeatedly re-placing the ice gloves is not only inconvenient but also affects the low-temperature effect. Utility Model Content
