Abdominal dialysis positioning device for nephrology department

Abstract

The invention discloses an abdominal dialysis positioning device for the nephrology department. The abdominal dialysis positioning device comprises a circular disc, a rubber ring, an elastic thin filmand a dialysis catheter. The circular disc comprises a middle part and a rotating part which constitute a circle. A fixing groove is formed in the rubber ring, and the periphery of the elastic thin film is fixedly connected with the upper surface of the rubber ring. An air exhausting pipe and a fixing sleeve are further fixedly connected to the elastic thin film, and the dialysis catheter is arranged in a mounting hole and the fixing sleeve in a sleeved-fit mode. The dialysis catheter is fixedly connected with the mounting hole. The abdominal dialysis positioning device has the beneficial effects that the structure is novel, the functions are practical, the abdominal dialysis positioning device is attached to the abdomen of a patient through the rubber ring, through air exhausting of theair exhausting pipe, the rubber ring is adsorbed to the abdomen of the patient to fix the positioning device, and the fixing effect is good; and the circular disc is convenient to mount and dismount and thus convenient to mount and clean, through rotary connection of the middle part and the rotating part, the abdominal dialysis positioning device can be attached to the abdomen of the patient in shape well, and the sealing effect is good.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a peritoneal dialysis positioner used in nephrology. Background technique [0002] Uremic patients require regular dialysis. At present, many patients are undergoing peritoneal dialysis, that is, peritoneal dialysis is performed by inputting peritoneal dialysis fluid from the outside of the human body through an external tube to maintain electrolyte balance. The pipeline is evenly perfused into the peritoneal cavity for 2-4 hours, and the dialysate of these metabolic wastes and excess water is released from the peritoneal cavity through the outer tube, and then filled with new peritoneal dialysate, so that the continuous circulation operation can continuously discharge toxins and If there is excess water, the patient needs to permanently install an outer tube on the abdomen. Therefore, the fixation of the outer tube for dialysis is very important. If it cannot be fixed, ...

At present, many patients are undergoing peritoneal dialysis, that is, peritoneal dialysis is performed by inputting peritoneal dialysis fluid from the outside of the human body through an external tube to maintain electrolyte balance. The pipeline is evenly perfused into the peritoneal cavity for 2-4 hours, and the dialysate of these metabolic wastes and excess water is released from the peritoneal cavity through the outer tube, and then filled with new peritoneal dialysate, so that the continuous circulation operation can continuously discharge toxins and If there is excess water, the patient needs to permanently install an outer tube on the abdomen. Therefore, the fixation of the outer tube for dialysis is very important. If it cannot be fixed, peritonitis will easily occur. Moreover, if the fixation is not good, the outer tube will be damaged, causing the patient to lose weight. secondary intubation pain

At present, traditional abdominal dialysis positioners used in nephrology mainly use bandages for positioning, and the positioning effect is poor, and the positioners are generally one-piece fixed structure, which is difficult to fit the shape of the patient's abdomen, resulting in poor sealing effect of the positioner, and The one-piece positioner structure is difficult to clean
