In-vitro fixing device for peritoneal dialysis catheter

Abstract

The invention discloses an in-vitro fixing device for a peritoneal dialysis catheter. The in-vitro fixing device comprises a fixing device body, wherein the fixing device body comprises a bellyband, wherein elastic bands are fixedly mounted on two sides of the bellyband, a first male Velcro tape is sewn on the rear side of one of the two elastic band, a first female Velcro tape is sewn on the front side of the other elastic band, the first male Velcro tape is matched with the first female Velcro tape, a catheter fixing mechanism and an iodophor cap fixing mechanism matched with the catheter fixing mechanism are arranged on the bellyband, the catheter fixing mechanism comprises a clamp seat fixedly mounted on the front side of the bellyband, an opening is formed in the upper side of the clamp seat, and a catheter is fixedly clamped in the clamp seat. The in-vitro fixing device is reasonable in design and convenient to operate, facilitates synchronous and rapid fixation for an iodophor cap and the catheter, prevents the wound from being pulled due to movement of the patient, prevents the iodophor cap from falling off from the catheter and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of catheter fixing equipment, in particular to an external fixing device for a peritoneal dialysis catheter. Background technique [0002] Peritoneal dialysis is a common method for removing metabolites and toxic substances in the body and correcting water and electrolyte balance disorders. It is easy to operate and has a wide range of applications. It can be performed without special equipment, and there is no extracorporeal circulation and no hemodynamic changes. , the dialysis is stable, and has a good therapeutic effect on the patient's condition. In the actual clinical operation process, after the peritoneal dialysis is completed, part of the peritoneal dialysis tube is exposed outside the patient's body. There is a povidone iodine cap installed at one end, but the extracorporeal extension catheter has caused inconvenience to the daily life of the patient. Therefore, medical staff usually use a fixing d...

Problems solved by technology

[0003] However, the existing fixation device does not achieve a good fixation effect by means of a cloth bag. Since the catheter and the iodophor cap are only placed in the cloth bag, when the patient is moving, the catheter and the iodine cap will also be caused by the movement of the patient. The phenomenon that the cap falls off from the cloth bag will even cause traction and friction to the stoma, often causing infection and affecting the recovery of the patient, which cannot meet the needs of use. above question
