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.
