Peritoneal dialysis catheter positioning and adjusting device

Abstract

The invention relates to a peritoneal dialysis catheter positioning and adjusting device which fixes and adjusts the position of a peritoneal dialysis catheter by utilizing the action of a magnetic force. The device comprises an in-vivo part arranged in the abdominal cavity of a human body and an in-vitro part arranged outside the abdominal cavity of the human body, wherein the in-vivo part comprises a peritoneal dialysis catheter arranged in the abdominal cavity of the human body; paramagnetic metal or paramagnetic alloy capable of receiving external magnetic force is embedded on the pipe section close to the tail end of the peritoneal dialysis catheter; and the in-vitro part comprises a movable magnetic force generating and adjusting device which indirectly acts on the paramagnetic metal or paramagnetic alloy of the in-vivo part in the abdominal cavity of the human body. The peritoneal dialysis catheter is positioned at a proper position in the abdominal cavity through the mediation of magnetic force, the drift of the peritoneal dialysis catheter is remarkably reduced or thoroughly eliminated, and the technological success of each time f peritoneal dialysis is ensured; and meanwhile, once in the case of catheter drift, non-operation in-vitro reset can be realized through the mediation effect of magnetic force, thus the pain of the patient suffering in operation is avoided, and additional economic burden is reduced.

Description

technical field [0001] The invention belongs to the technical field of medicine and relates to peritoneal dialysis treatment of renal failure, in particular to a peritoneal dialysis tube positioning and adjusting device. Background technique [0002] Renal failure is a pathological state of partial or complete loss of renal function caused by the development of various chronic kidney diseases in the later stage. When the disease progresses to end-stage renal failure, that is, uremia, the patient must receive kidney transplantation or kidney replacement therapy to maintain life. It is estimated that approximately 1.5 million patients worldwide currently receive renal replacement therapy. Among them, peritoneal dialysis (referred to as peritoneal dialysis) is one of the main methods of renal replacement therapy. According to the Shanghai Dialysis Registration Report in 2009, peritoneal dialysis accounts for about 21.1% of renal replacement therapy, and with the support of nat...

Problems solved by technology

However, since the "self-positioning" peritoneal dialysis tube needs to rely on gravity, there are certain requirements for the patient's position. When the patient is in a special position such as lying on his side, the end of the peritoneal dialysis tube may be displaced due to the effect of gravity, which will affect peritoneal dialysis. Treatment effect, severe cases even need a second operation to adjust the position of the peritoneal dialysis tube
