Peritoneum dialysis liquid exchange auxiliary device

Abstract

The invention provides a peritoneum dialysis liquid exchange auxiliary device and relates to the technical field of peritoneum dialysis. The structure of the peritoneum dialysis liquid exchange auxiliary device comprises a first guide rail and a second guide rail, wherein the first guide rail is provided with a first bracket and a second bracket which can slide along the first guide rail; a third bracket, which can slide along the second guide rail, is arranged on the second guide rail; in a liquid exchange process, when a dialysis liquid connector is in butt joint with a peritoneum dialysis short pipe, the dialysis liquid connector is clamped on the first bracket, and the peritoneum dialysis short pipe is clamped on the second bracket; by pushing the first bracket and the third bracket, the dialysis liquid connector and the peritoneum dialysis short pipe, which are accurately aligned, are connected; after liquid is exchanged, the dialysis liquid connector is separated from the peritoneum dialysis short pipe, and an iodophor cap is clamped on the second bracket; by pushing the second bracket and the third bracket, the iodophor cap is aligned to a pipe opening of the peritoneum dialysis short pipe and covers the pipe opening. In a whole liquid exchange process, the auxiliary device can be used for effectively preventing touch pollution and particularly can realize accurate alignment for patients with amblyopia or patients with hand tremor; the convenience for liquid exchange operation is greatly improved.

Description

technical field [0001] The invention relates to the technical field of peritoneal dialysis, in particular to an auxiliary device for peritoneal dialysis fluid replacement. Background technique [0002] Peritoneal dialysis, referred to as peritoneal dialysis, is to use the characteristics of the peritoneum as a semipermeable membrane to pour the prepared dialysate into the patient's peritoneal cavity through the catheter at regular intervals, and then continuously replace the dialysate in the peritoneal cavity to eliminate the metabolic rate in the patient's body. A treatment for waste, toxic substances, and for the purpose of correcting disturbances in water, electrolyte, and acid-base balance, often used in the treatment of patients with end-stage renal disease. [0003] Peritoneal dialysis liquid replacement is generally to connect the short peritoneal dialysis tube with the dialysate connector, and then drain the old dialysate from the peritoneal cavity, then infuse new d...

Problems solved by technology

For the above requirements of changing the fluid, the patient can generally do it carefully, but peritoneal dialysis is a long-term treatment process, and any negligence of the patient when changing the fluid may cause peritoneal infection, especially for elderly patients or diabetic patients. , because most of them have weak eyesight or hand tremors, so when changing fluids in peritoneal dialysis, their hands are easy to touch the nozzle of the short peritoneal dialysis tube, the interface of the dialysate connector and the edge of the iodine cap, thereby increasing The probability of peritoneal infection, and when connecting the short peritoneal dialysis tube and the dialysate connector, it is difficult to accurately align the mouth of the short peritoneal dialysis tube with the interface of the dialysate connector, and cover the mouth of the short peritoneal dialysis tube with povidone iodine When using caps, it is difficult to accurately cover the iodine cap on the nozzle of the short peritoneal dialysis tube, which will cause a lot of inconvenience to the peritoneal dialysis fluid change operation process, and is prone to contact contamination. Therefore, it is necessary to design an auxiliary peritoneal dialysis Auxiliary devices for liquid exchange operations are of great significance
