peritoneal dialysis replacement aid

technical field

The invention relates to the technical field of peritoneal dialysis, in particular to an auxiliary device for peritoneal dialysis fluid replacement.

Background technique

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.

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 dialysate, then separate the dialysate connector and the short peritoneal dialysis tube and use them together A povidone iodine cap covers the orifice of the peritoneal dialysis tubing. During the liquid change process, it is required that the hand should not touch the nozzle of the short peritoneal dialysis tube, the interface of the dialysate connector and the edge of the iodine cap, otherwise bacteria may enter the patient's abdominal cavity through the above-mentioned instruments during the liquid change process , and then easily lead to peritonitis or other complications due to infection. 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.
