Special waterproof protection device for peritoneal dialysis catheter for peritoneal dialysis patient

Abstract

The invention relates to the technical field of medical assistance equipment, in particular to a special waterproof protection device for a peritoneal dialysis catheter for a peritoneal dialysis patient. The special waterproof protection device comprises an outer bonding edge, wherein an air extraction bag is fixedly arranged in the outer bonding edge; one side of the front side of the air extraction bag fixedly communicates with a one-way valve; an inner plate is fixedly arranged in the air extraction bag; a connection seat cover is fixedly welded at the middle position of the inner plate; the middle position of the front side of the connection seat cover fixedly communicates with a connection sleeve; and one end of the front side of the connection sleeve fixedly communicates with a protective cover. According to the special waterproof protection device, the air extraction bag is fixed between the outer bonding edge and the inner plate in a surrounding manner, so that the device can be clung to the outer side of a wound of a patient under the action of air pressure through the air extraction operation in the air extraction bag, and external water flow is effectively prevented fromentering the protected wound inside the device; and meanwhile, the shape of the connection sleeve is set to be inclined downwardly, so that accumulated water in the shower is effectively prevented from entering the wound position from the joint of the connection sleeve and a cannula main body through the guide of the connection sleeve.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a special waterproof protection device for peritoneal dialysis tubes for peritoneal dialysis patients. Background technique [0002] Peritoneal dialysis is a treatment method that uses the peritoneum as a semi-permeable membrane for medical dialysis. When peritoneal dialysis is working, the prepared dialysate is regularly and regularly poured into the patient's peritoneal cavity through the catheter through the action of gravity. There is a gradient difference in solute concentration on both sides, and the solute on the high-concentration side moves to the low-concentration side, causing water to move from the hypotonic side to the hypertonic side, and the peritoneal dialysate is constantly replaced to eliminate metabolism in the body Products, toxic substances and the purpose of correcting water and electrolyte balance disorders are often used in the treatmen...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a special waterproof protection device for peritoneal dialysis tubes for peritoneal dialysis patients, so as to solve the problem of poor waterproof protection at the connection between the intubation tube and the abdomen of peritoneal dialysis patients in the above-mentioned background technology, which leads to inconvenience in daily life for patients. When the patient takes a bath, accumulated water tends to pool at the wound site, causing wound infection
