Peritoneum dialysis locator for nephrology

Abstract

The invention relates to a peritoneum dialysis locator for nephrology. The locator comprises a dialysis outer tube, an outer suction cup is arranged in the middle of the dialysis outer tube, a sealingring is hingedly mounted on the inner side of the upper portion of the outer suction cup, the inner side of the sealing ring is in contact with the dialysis outer tube, the bottom surface of the outer suction cup is hingedly provided with a circle of positioning ring, a large sealing ring is fixedly mounted on the outer side of the bottom surface of the positioning ring, two uniformly distributedannular grooves are respectively formed in the bottom surface of the middle of the positioning ring, the annular grooves are respectively provided with cooperating air bags, the bottom surfaces of the air bags are fixedly provided with circles of sealing strips, a first adhesive layer is fixedly mounted on the inner side of the bottom surface of the positioning ring, an inclined piston tube is fixedly mounted on the left side of the outer suction cup, a through groove is formed in the life side of the middle of the piston tube, a moving block is arranged in the through hole, and the moving block can move along the through groove. The locator has reasonable structural design, simple installation, time and labor saving and firm fixing, an inner suction cup and the outer suction cup are double-fixed, the fixing effect is good, double sealing improves air tightness of fixing, and the air leakage or the poor fixing effect is avoided.

Description

technical field [0001] The invention belongs to the field of medical appliances, in particular to a positioner for peritoneal dialysis in nephrology. Background technique [0002] Uremic patients need regular dialysis, and many patients use peritoneal dialysis, that is, enter the peritoneal dialysis solution from the outside of the human body through an external tube for peritoneal dialysis to maintain electrolyte balance. The process of peritoneal dialysis is perfusion in series and parallel forms The dialysate is uniformly infused into the peritoneal cavity through the pipeline for 2-4 hours according to the doctor's order, 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 cycle operation can To remove toxins and excess water in the body, the patient needs to permanently install a dialysis tube on the abdomen. Generally, the dialys...

[0002] Uremic patients need regular dialysis, and many patients use peritoneal dialysis, that is, enter the peritoneal dialysis solution from the outside of the human body through an external tube for peritoneal dialysis to maintain electrolyte balance. The process of peritoneal dialysis is perfusion in series and parallel forms The dialysate is uniformly infused into the peritoneal cavity through the pipeline for 2-4 hours according to the doctor's order, 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 cycle operation can To remove toxins and excess water in the body, the patient needs to permanently install a dialysis tube on the abdomen. Generally, the dialysis tube is fixed on the human skin with medical adhesive tape. If it is not fixed, peritonitis will easily occur, and the outer tube will be damaged, causing the patient's second intubation pain, and the traditional peritoneal dialysis positioner used in nephrology lacks a sealing device, and the installation process of positioning equipment is more troublesome
