Fixed protection device for PD (peritoneal dialysis) external short pipe

Abstract

The invention discloses a fixed protection device for a PD (peritoneal dialysis) external short pipe. The device comprises a fixing cover, a yielding groove, a fixing plate, a yielding hole, a first spring, a pressing plate, a snap ring, an ultraviolet germicidal lamp, a base, an observation cover plate, a sliding rod, a sliding block, a second spring and a shading plate. The fixed protection device for the PD external short pipe has ingenious structure and powerful functions, the external short pipe and a port of a dialysate bag can be connected and fixed more firmly during external connection for change operation of a dialysate by protective wearing type design, and the problem of pipe falling off and separation is greatly solved; besides, the device can be carried, operated and used conveniently, clinical practicality is expanded; moreover, purposes of sterilization and disinfection can be achieved by the cooperation effect of an internal sterilization mechanism, breeding of bacteria is effectively reduced, the effects of cleaning, sanitation and infection prevention are achieved, and finally, the purpose of clinical popularization and application is well achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a fixing and protecting device for a peritoneal dialysis external short tube. Background technique [0002] Peritoneal dialysis (PD) is a dialysis method that uses the body's own peritoneum as the dialysis membrane. The dialysate poured into the peritoneal cavity exchanges solutes and water with the plasma components in the capillaries on the other side of the peritoneum, removes the retained metabolites and excess water in the body, and at the same time replenishes the necessary substances for the body through the dialysate. Through continuous renewal of peritoneal dialysis fluid, the purpose of renal replacement or supportive treatment can be achieved. [0003] Chronic kidney disease is on the rise in my country and has become a common disease that seriously threatens human health and causes serious economic burdens on families and society. Due to the advantages of si...

Problems solved by technology

[0005] At present, the pipeline connection system of peritoneal dialysis therapy consists of a peritoneal dialysis catheter made of silicone placed in the abdominal cavity and connected with a short external short tube of peritoneal dialysis made of silicone through a titanium connector, and the other end of the short external tube is connected with the pipeline of the peritoneal dialysis solution bag. Peritoneal dialysis patients change the peritoneal dialysis solution 3-5 times a day. Therefore, the most frequently used and most vulnerable part of the connection system is the peritoneal dialysis external short tube. Generally, the external short tube is replaced every 3-6 months. In addition, the external short tube The tube is used by patients in daily peritoneal dialysis. If the connection between the peritoneal dialysis fluid bag interface and the external short tube joint is not firm, it is easy to cause microbial invasion, or the external short tube and the peritoneal dialysis fluid bag fall off and separate, eventually causing risk, which brings great potential safety hazards to clinical promotion and application. In view of the above defects, it is necessary to design a fixed protection device for peritoneal dialysis external short tube
