Description

Disposable simple external transplanting renal artery perfusion device Technical Field The invention relates to the technical field of medical appliances, in particular to a disposable simple external transplantation renal artery perfusion device. Background Allogeneic kidney transplantation is now widely practiced by various clinical centers as the most effective treatment for end-stage renal disease. The kidneys need to be removed for repair and infusion prior to performing a kidney transplant. The perfusion aims at draining excessive blood in kidney to prevent micro thrombosis after transplantation, and at detecting leakage to ligate small blood vessels and lymphatic vessels around kidney pedicles to prevent postoperative bleeding and exudation. The traditional perfusion method is that the head end of the infusion leather strip is inserted into the renal artery to be directly perfused by a doctor, and the disadvantage is that: 1. The antibiotics are infused immediately before the transplantation of the multi-unit suggestion, and the assistance is also needed to cooperate; 2. The hand-held perfusion has poor stability and fixation, and arterial perfusate is easy to flow out, so that waste is caused; 3. The hand-held force is different, and the head end of the infusion leather strip is easy to damage the inner membrane of an artery, so that arterial injury, postoperative arterial stenosis, thrombosis and other complications are caused. 4. Many transplantation centers are used to preoperative polymyxin in vitro infusion, typically divided into two groups of personnel, one group of row recipients being prepared and the other group of row transplant kidney in vitro infusion.
