Embodiment 1

[0029] A catheter fixation device for peritoneal dialysis, such as figure 1 , 2 As shown, it includes a first fixing member 2 , an anti-adhesion connecting member 3 and a second fixing member 4 which are connected in sequence. The first fixing member 2 is a short tube made of easy-adhesion material (such as polyester material), and its inner diameter matches the outer diameter of a conventional peritoneal dialysis catheter. The anti-adhesion connector 3 is a section of irregular silica gel short tube, and the silica gel short tube has different lengths at different angles. The length of the same silica gel short tube can be gradually changed in the range of 2 to 4 cm, and its inner diameter is significantly larger than Outer diameter of conventional peritoneal dialysis catheters. The upper and lower ends of the irregular silica gel short tube are respectively fixedly connected with the first fixing member 2 and the second fixing member 4 . The second fixing member 4 is a co...

Embodiment 2

[0031] An easy-to-remove peritoneal dialysis tube assembly, the structure of which is as follows image 3 As shown, it includes a silicone catheter 1 , a first fixing piece 2 , an anti-adhesion connecting piece 3 and a second fixing piece 4 .

[0032] like image 3 As shown, one end of the silicone catheter 1 with a scale on the outer surface is provided with a siphon hole 11, which is convenient for intra-abdominal liquid drainage or perfusion, and a first fixing member 2 is provided near the other end; the first fixing member 2 can be about 4 cm A length of polyester sleeve cuff is tightly sleeved on the outer surface of the silicone catheter 1. like figure 1 , 2 As shown, one end of the anti-adhesion connector 3 is fixedly connected to the bottom end of the first fixing member 2 , and the other end is fixedly connected to the second fixing member 4 distributed on both sides of the silicone catheter 1 .

[0033] like image 3 , 4 As shown, the anti-adhesion connector 3...

Abstract

The invention provides a catheter fixing device for peritoneal dialysis and a peritoneal dialysis catheter assembly easy to pull out. The catheter fixing device for peritoneal dialysis comprises a first fixing piece, an anti-sticking connecting piece and a second fixing piece, the first fixing piece is in a short tube shape, and the inner diameter of the first fixing piece is matched with the outer diameter of a peritoneal dialysis catheter. The second fixing piece is a composite sheet formed by compounding an anti-sticking material layer and an easily-sticking material layer; and the anti-sticking connecting piece is respectively connected with the first fixing piece and the second fixing piece. The peritoneal dialysis catheter assembly comprises a catheter, a first fixing piece, a second fixing piece and an anti-sticking connecting piece. Multiple siphon holes are formed in one end of the conduit; the first fixing piece is fixedly connected to the outer surface of the guide pipe in a sleeving mode. The second fixing piece is used for being bonded to the surface of the rectus abdominis anterior sheath through the easily-bonded material layer. According to the peritoneal dialysis catheter assembly, the stripping difficulty of the catheter and muscular tissue after peritoneal dialysis is greatly reduced, and the peritoneal dialysis catheter is easier to pull out.

Description

technical field [0001] The invention relates to medical equipment, in particular to a fixing device for a peritoneal dialysis catheter and a peritoneal dialysis tube assembly. Background technique [0002] Peritoneal dialysis is a home-based renal replacement therapy for patients with end-stage chronic kidney disease. A peritoneal dialysis tube is inserted into the patient's abdominal cavity, and the peritoneal dialysis fluid can be infused and drained to remove toxins and water, thereby maintaining the relative stability of the body's internal environment. . When a patient stops peritoneal dialysis treatment for various reasons (kidney transplant, death, conversion to hemodialysis), the peritoneal dialysis tube needs to be removed. [0003] At present, the peritoneal dialysis tube commonly used is a silicone tube with a siphon hole at the end, and the peritoneal dialysis tube is divided into an intra-abdominal segment, a subcutaneous segment, and an extra-abdominal segment...
