Description
Technical Field
The utility model relates to the technical field of medical equipment, specifically, relate to a prevent wrapping up type peritoneal dialysis pipe.
Background
Currently, a more effective treatment for patients with renal failure is dialysis, which is a treatment in which components in body fluid are discharged through a semipermeable membrane. Peritoneal dialysis is a dialysis method using the peritoneum of a human body as a dialysis membrane, and the principle of the peritoneal dialysis is that the dialysate filled into the peritoneal cavity exchanges solute and moisture with the plasma components in the capillary vessel on the other side of the peritoneum, so that residual metabolites and excessive moisture in the body are removed, substances necessary for the body are supplemented by the dialysate, and the purpose of kidney substitution or treatment support is achieved by continuously updating the dialysate.
Before the peritoneal dialysis treatment, a safe passage needs to be established for liquid replacement, a small operation needs to be performed to insert a dialysis catheter into the abdominal cavity, one end of the tube is left in the abdominal cavity, the middle end of the tube is buried under the skin, and the other end of the tube is left outside the abdominal wall. In the peritoneal dialysis treatment, peritoneal dialysis solution is filled into the abdominal cavity through a peritoneal dialysis catheter. One side of the peritoneum in the peritoneal cavity is blood containing waste and redundant water in peritoneal capillaries, the other side is peritoneal dialysis solution, and the waste and redundant water in the blood permeate the peritoneal membrane to enter the dialysis solution. After a period of time, the peritoneal dialysis solution containing waste and excess water is drained from the peritoneal cavity and a new peritoneal dialysis solution is filled in, thus continuously circulating to achieve the treatment effect.
In a peritoneal dialysis catheter (made of silica gel) used in the prior art, as shown in fig. 1, two lantern rings 003 are arranged in the middle of the catheter for fixing the peritoneal dialysis catheter to the abdomen, the end 001 of the catheter is open, and a side hole 003 with a needle point is arranged at the end of the catheter to draw out and feed dialysate in the abdomen. However, it has been found clinically that the existing peritoneal dialysis catheter has some drawbacks during dialysis treatment: 1. the dialysis catheter is easy to drift, and the dialysis holes on the catheter head are blocked due to the surrounding of structures in abdominal cavities such as omentum majus and the like in the later period, so that the dialysis fluid drainage is obstructed, a doctor has to pull out an old catheter and replace a new catheter through a surgical operation, so that the economic burden of a patient is increased, the patient suffers from a lot of pains, the physical quality of the patient is reduced due to multiple operations, and the later-period treatment is not facilitated; 2. when the catheter head of the dialysis catheter is in an abnormal state, the catheter head cannot be found in time and needs to be found after being observed by a doctor, which brings great pain to a patient and brings great inconvenience to the operation of medical staff.
For solving above-mentioned problem, also there is relevant solution to emerge at present, and someone adopts the mode of setting up anti-blocking projection or sleeve pipe on the dialysis portion of dialysis tubing, and someone will dialysis tube body sets up many dialysis tubing side by side or sets up dialysis catheter to the helical shape, however these schemes or structure are complicated, prevent that stifled structure can become the hindrance that the operation was gone on, make the degree of difficulty big, or can increase the operation incision, increased the pain and the risk of patient's operation, also do not benefit to the recovery yet.
