Description
Technical Field
The utility model relates to the technical field of peritoneal dialysis catheter placement in nephrology department, in particular to a peritoneal dialysis catheter with a metal tube embedded in the wall of the catheter for preventing the catheter from drifting.
Background
Peritoneal dialysis is one of the important renal replacement therapies for patients with chronic kidney disease. The peritoneal dialysis catheter is a key part for establishing a successful peritoneal dialysis path, and the structure of the catheter and the position of the catheter in the peritoneal cavity are particularly important for ensuring whether the peritoneal dialysis is carried out smoothly for a long time. Research shows that peritoneal dialysis catheter drifting (floating tube) is the most common complication related to peritoneal dialysis, the incidence rate is 12.7% -35%, the peritoneal dialysis solution flow is reduced and the flow speed is slowed down because the intra-abdominal section of a light catheter is floated upwards out of a true pelvis, and the peritoneal dialysis solution cannot be discharged because the intra-abdominal section of a heavy catheter is floated upwards out of the plane of the peritoneal dialysis solution. The floating tube is one of the important reasons for the effective rate of peritoneal dialysis and the failure of peritoneal dialysis. Among the many causes of tube floating, the structure of the catheter itself is one of the important factors, in addition to the external factors such as improper posture, improper tube placement, increased abdominal pressure, abnormal bowel movement and peritonitis. At present, the peritoneal dialysis catheters commonly used in domestic clinic are 4 types: straight Tenckhoff tubes, Tenckhoff curls, straight gooseneck tubes, and curls. The material of the existing peritoneal dialysis catheter mainly adopts silicon rubber, the weight is light, the floating tube occurrence rate is relatively high, and the fixity in the abdominal cavity is poor, so that the traditional peritoneal dialysis catheter is adopted for placing the catheter, and the complication of floating the catheter still exists. To date, a lack of prospective, randomized controlled studies of large samples has demonstrated which catheters are more advantageous in reducing catheter-related complications.
In addition, when the floating tube is generated, the reduction treatment is needed, including manual reduction, gravity reduction, peristalsis reduction, laparoscopic reduction and the like, and the effect of the reduction methods is not very ideal, so that the peritoneal dialysis treatment cannot be effectively carried out, and the survival rate of the peritoneal dialysis catheter is finally reduced.
Therefore, the peritoneal dialysis catheter is improved to reduce the incidence rate of early catheter dysfunction, namely floating catheter, and has great significance for relieving the pain of peritoneal dialysis patients and improving the survival rate of peritoneal dialysis technology.
Disclosure of Invention
In order to overcome the defect that the peritoneal dialysis catheter in the prior art is easy to have catheter drift after being placed in the catheter, the utility model provides the peritoneal dialysis catheter with a metal tube embedded in the wall of the catheter for preventing the catheter from drifting.
The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides a peritoneal dialysis catheter of pipe is prevented drifting by embedding metal pipe in the wall of pipe, is including arranging the hollow pipe abdomen inner segment of silicon rubber in the abdominal cavity in, the basin intracavity is arranged in to the lower 2/3 part of pipe abdomen inner segment, for pipe pelvic cavity section, it has the side opening and buries the metal pipe in the pipe wall to fretwork on the pipe wall of pipe pelvic cavity section.
Foretell side opening, the diameter is 0.5mm, is located on the pipe wall of pipe basin chamber section, four side openings are a set of, are two liang of relative evenly distributed, and every 10mm is a set of, total 11 groups, so make the intracavity outside of pipe basin chamber section communicates with each other, and the contact surface of intraductal and pelvic cavity dislysate during the increase dialysis to improve dislysate flux.
Foretell tubular metal resonator is hollow cylinder ring-type, and the internal diameter is 4mm, and the external diameter is 6mm, and axial length is 5mm, and the material adopts the great lead of density or stainless steel, buries in the pipe wall of pipe pelvic cavity section, be located the centre of per two sets of side openings, the tubular metal resonator is total 11 groups, with the side opening is even alternate distribution on the pipe wall of pipe pelvic cavity section, has both increased the gravity of pipe pelvic cavity section in order to float the pipe, does not show the circulation that reduces the dislysate again.
In the technical scheme, the axial length of the inner section of the catheter abdomen is 15mm, the inner diameter is 3mm, and the outer diameter is 7 mm.
The peritoneal dialysis catheter has the beneficial effects that the peritoneal dialysis catheter utilizes the metal pipe buried in the catheter wall to increase the gravity of the catheter lumen section, so that the catheter lumen section is not easy to float under the action of the gravity, and the metal pipe and the side holes are uniformly distributed on the catheter wall of the catheter lumen section at intervals, so that the occurrence rate of floating pipes is effectively reduced under the condition of not influencing the drainage effect of the peritoneal dialysis catheter, and the survival rate of the peritoneal dialysis technology is improved.
