MODIFIED catheters for peritoneal dialysis in children

摘要

The modified catheter for peritoneal dialysis in children. The invention relates to medicine, namely to the cardiovascular surgery. The purpose of the utility model is unworthy of technical prevention of complications of peritoneal dialysis. The goal is achieved technical solution is: modified catheter for peritoneal dialysis in children consisting of a polypropylene tube 7 mm in diameter with multiple holes at the distal end, via a tube 7 mm, diameter held second polypropylene tube of 3 mm diameter, with an opening at the distal end , which is derived from the lumen of the catheter through a tight hole of 3 mm in a polypropylene conductor connecting the catheter with a main tube for dialysis. The novelty of the proposed device is the presence of an additional tube of 3 mm inside diameter of the catheter, which is derived from it through the lumen of the seal opening in the conductor. The proposed device operates as follows. Introduction and removal of dialysis solution is carried out through the main drain pipe. In case of violation of the drainage catheter functions to evacuate the inner tube solution is used. This is achieved in that the occlusive gland lumen of the outer tube, the inner tube is passable, and the solution can flow away freely on it from the abdominal cavity. The proposed device allows you to perform peritoneal dialysis without compromising drainage catheter function, providing a reliable replacement therapy in cardiac surgery patients with acute renal failure.
