Isolated kidney perfusion system

Abstract

The invention discloses an isolated kidney perfusion system, and relates to the technical field of kidney transplantation. According to the invention, a liquid conveying pipeline is used as a main body; a liquid inlet pipe, a liquid dripping bucket, a fluid speed regulation roller and an outflow assembly are sequentially arranged on the conveying pipeline in series; and through arrangement of theabove-mentioned structures, the isolated kidney perfusion system provided by the invention can make up the defect that a perfusion device used in the kidney transplantation process in the prior art isgenerally a self-made simple device and is inconvenient when a plurality of blood vessels are encountered or the blood vessels are thin. During kidney perfusion, a medicine can be injected through above-mentioned devices; a flow speed can be adjusted through a pulley; a pressure can be generated during liquid conversion and extrusion through a soft ball to facilitate perfusion; a proper siliconetube can be selected for perfusion according to the thickness and number of kidney arteries; thus, the isolated kidney perfusion system provided by the invention has the advantages of simple structure, widely-available materials, convenient operation, low price, practicality, sufficient perfusion, scientific and reasonable structure and safe and convenient use.

Description

technical field [0001] The invention relates to the technical field of kidney transplantation, in particular to an isolated kidney perfusion system. Background technique [0002] A kidney transplant usually takes about three to four hours. The surgery is performed on the abdomen, and the implanted new kidney is placed in the lower abdomen near the groin (such as the right iliac fossa). There is no need to remove the two original kidneys, but only the blood vessels of the new kidney need to be connected to the recipient. The recipient's abdominal blood vessels (such as internal / external iliac artery, external iliac vein), and the ureter of the new kidney implanted in the recipient's bladder wall. [0003] In kidney transplantation, when the kidney is isolated from the body, it is necessary to immediately perfuse the kidney with 4°C preservation solution to flush out the blood in the kidney in time until the kidney is pale and no red liquid flows out. [0004] For the above ...
