Dialysis catheter protecting cover

Abstract

The invention discloses a dialysis catheter protecting cover, and aims at providing a dialysis catheter protecting cover which is simple in structure, low in cost, waterproof and convenient for a dialysis patient to have a bath. According to the technical scheme, the dialysis catheter protecting cover comprises a sealed protecting cover body, an opening for allowing a dialysis catheter to go in and out is formed in the protecting cover body, and a sticking piece is arranged at the edge of the opening in a sealing and matched mode. The exposed dialysis catheter is protected by arranging the protecting cover body, the sticking piece is arranged at the edge of the opening in the sealing and matched mode, that is, the sticking piece is used for fixing the protecting cover body at the outer side of a wound of a human body, therefore, the wound of the human body and the dialysis catheter are both in a completely-isolated state, and the infection risk is reduced; when liquid such as water is permeated into a protected area, that is, the protecting cover body, the internal condition can be observed, and people are prompted to do urgent treatment. According to the dialysis catheter protecting cover, the structure is simple, the cost is low, the isolation effect is good, and the problem that infection is prone to occurrence when the patient has the bath is solved; in addition, multiple safety barriers are arranged, and therefore the probability that the patient is infected is greatly decreased.

Description

technical field [0001] The invention relates to medical equipment, more specifically to a protective cover for a dialysis catheter. Background technique [0002] Dialysis is a separation and purification technique that separates small molecules from biological macromolecules by the principle of small molecules diffusing into water or buffer through a semipermeable membrane. Dialysis therapy is a treatment method that allows the component solutes or water in body fluids to be excreted from the body through a semipermeable membrane. Generally, it can be divided into two types: hemodialysis and peritoneal dialysis. At present, dialysis is the main treatment method adopted by many hospitals in the treatment of uremia, renal failure and other kidney diseases. [0003] When a patient is treated with dialysis, before the patient's internal arteriovenous fistula matures, a temporary blood dialysis catheter is often used as the patient's vascular access. The temporary blood dialysis...

Problems solved by technology

This method has the following defects: since the sterile gauze only plays an isolation role, it cannot completely isolate and protect the dialysis catheter, especially it cannot be waterproof, so that the patient cannot take a bath easily, and cannot feedback whether the external water has penetrated, and the patient's Great inconvenience to life and increased risk of infection
