Peritoneal dialysis connecting instrument for kidney internal medicine and peritoneal dialysis connecting method

Abstract

According to the peritoneal dialysis connecting instrument and method for the kidney internal medicine department, a core column and a seat sleeve are each provided with a flow channel or a hole allowing peritoneal dialysis liquid to flow through, the flow channel or the hole in the core column is connected with a conveying channel so as to continue to convey the peritoneal dialysis liquid, and the core column is further connected with a high-elastic hose; a channel-steel-shaped left pressing block is embedded in the left side wall in the cavity, and the right side of the right pressing block is slidably connected into the right side wall of the cavity; the second connector comprises a bottle-cap-shaped threaded cap, a plurality of air holes are formed in the position, close to the inner side wall, of the threaded cap, a round boss is arranged in the center of the threaded cap, a liquid outlet pipe is coaxially embedded and fixed to the center of the boss, and the piston disc is axially and slidably connected with the inlet end of the liquid outlet pipe and matched with the inlet end of the liquid outlet pipe in a movable sealing mode. The piston disc can pass through the inlet end of the drainage groove to enable liquid on the left side of the piston disc in the liquid outlet pipe to flow to the right side. The connecting instrument is simple and compact in structure, convenient to operate and capable of fully exhausting air during connection.

Description

technical field [0001] The invention relates to the technical field of peritoneal dialysis equipment, and more specifically, relates to a peritoneal dialysis connecting device and a connecting method for nephrology. Background technique [0002] Peritoneal dialysis is a kind of renal replacement therapy. It uses the peritoneum as a dialysis membrane to exchange solutes and water between the dialysate infused into the peritoneal cavity and the plasma components in the capillaries on the other side of the peritoneum to remove retained metabolites in the body. And excessive water, at the same time through the dialysate to supplement the substances necessary for the body, through the continuous renewal of the peritoneal dialysis, to achieve the purpose of kidney replacement or supportive treatment. When performing peritoneal dialysis on a patient, the peritoneal fluid needs to be delivered to the patient's peritoneal cavity, but the existing equipment is inconvenient to connect ...
