Fixing band for peritoneal dialysis catheter

Abstract

The invention relates to a fixing band for a peritoneal dialysis catheter. The fixing band comprises a long strip-shaped bellyband main body, wherein magic stickers are arranged at two ends of the bellyband main body for fixing the bellyband to the belly; hook surfaces of at least two catheter fixing rings are long strip-shaped magic stickers are fixedly arranged on the bellyband main body, and the hair sides of the magic stickers are vertical to the outer side of the bellyband main body; a short pipe fixing ring is used for fixing a short pipe at the tail end of the catheter; and an opening where a peritoneal dialysis catheter penetrates through is also formed in the bellyband main body. The catheter fixing ring can fix and protect the external catheter properly, the external catheter isprevented from sliding, and daily activity and sleep are not limited by positions, traction of an external pipe can be avoided, the life quality and the treatment compliance are improved, and peritoneal dialysis is smoothly carried out. Bleeding at a tunnel exit and an infection occurrence rate can be reduced, and the pain of patients and the economical burden are alleviated.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a peritoneal dialysis catheter fixing belt. Background technique [0002] Peritoneal Dialysis (PD) is a dialysis method in which the peritoneum is used as the dialysis membrane, which can fully remove metabolites and water in the body and play the role of kidney replacement. Peritoneal dialysis has little impact on hemodynamics, and does not require vascular puncture, and can effectively protect residual renal function. After training, patients can complete the treatment process by themselves. It is the main renal replacement for patients with end-stage renal disease (End-Stage Renal Disease, ESRD). One of the treatments. Peritoneal dialysis is to insert a soft silicone catheter into the peritoneal cavity, through which the peritoneal fluid is poured into the peritoneal cavity, relying on the semipermeable membrane properties of the peritoneum to exchange sub...

AI Technical Summary

Problems solved by technology

[0005] The traditional surgical abdominal belt is large and has poor air permeability. When the pressure is too large, it is easy to cause skin pressure sores. If the pressure is too small, it will cause the catheter to shift or even cause damage. It is not suitable for long-term use.

[0006] In the past, there was a method of using a tube top to place the external tube of the peritoneal dialysis. Although the comfort is very good, there is curling during use or the tube top shifts with the movement of the abdominal muscles, which cannot effectively avoid the pulling of the tube

[0007] In the existing abdominal belt, the outer tube is put into the pocket provided by the abdominal belt. If it is not fixed, the tube is easy to come out by itself

[0008] In addition, some existing improved abdominal belts mainly use elastic rings / bands to fix the catheter, but this method still causes the catheter to be free in it, making the catheter fixation unstable; and when in use, the catheter inserted into the abdomen It is necessary to go around the abdominal belt and then pass into the catheter fixing ring, so that the patient will still suffer some pain during the movement

[0009] The abdominal belts that are currently or have been used above often cause bleeding, infection, and granulation hyperplasia at the outlet of the catheter due to loose fixation, which seriously affects the quality of dialysis, increases the burden on the patient, and brings pain to the patient.
