Device for automatic switching and connecting of peritoneal dialysis joints

Abstract

The invention discloses a device for automatic switching and connecting of peritoneal dialysis joints. The device comprises an upper cover, a base frame, a pipeline joint-fixing mechanism and a rotary self-balancing mechanism, the upper cover is rotatably connected with the base frame, a start button for controlling the rotary self-balancing mechanism is arranged on the outer side of the base frame, the pipeline joint-fixing mechanism and the rotary self-balancing mechanism are mounted in the base frame, the rotary self-balancing mechanism is used for position exchange of an iodophor cap and a dialysate joint, the pipeline joint-fixing mechanism is used for connection and fixation of a patient end pipeline joint and the iodophor cap or the dialysate joint, the rotary self-balancing mechanism comprises a cam mechanism, a gear transmission mechanism and a rotating mechanism, the cam mechanism is fixedly connected to the front end and the rear end of the base frame, the cam mechanism is rotationally connected to the gear transmission mechanism, the gear transmission mechanism is fixedly mounted in the base frame, and the gear transmission mechanism is in meshed connection with the rotating mechanism; and the device realizes automatic separation of the patient end joint and the iodophor cap, automatic position exchange of the iodophor cap and the dialysate joint and automatic connection of the patient end joint and the dialysate joint or the iodophor cap.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a device for automatic conversion and connection of peritoneal dialysis joints. Background technique [0002] Peritoneal dialysis uses the peritoneum as a dialysis membrane, injects dialysate into the peritoneal cavity, and uses the plasma in capillaries and microvessels on both sides of the membrane to meet the solute concentration gradient and osmotic gradient in the dialysate in the peritoneal cavity, through diffusion, convection and ultrafiltration. It is a treatment method to remove metabolic waste and excess water retained in the body. [0003] With the continuous acceleration of the aging process of the global population, the incidence of end-stage renal disease continues to rise worldwide. As one of the important methods of replacement therapy for patients with end-stage renal disease, peritoneal dialysis treatment has a high early survival rate and good residu...

Problems solved by technology

[0005] The survey of relevant literature shows that irregular operation is the main cause of peritonitis, mainly due to not wearing a mask during operation and irregular hand washing. Open the povidone iodine cap of the patient end interface and the protective sleeve of the dialysate interface in a simple way, but for some older patients, some irregular operations will inevitably occur, which will increase the risk of peritonitis
