During the indwelling period, there is no need to puncture the skin each time during dialysis, and only the needle is inserted into the catheter. However, it has been widely used in clinical practice. However, after the catheter is indwelled on the patient, the exposed part of the catheter joint is relatively large, and the patient is easy to pull when putting on and taking off clothes or taking items, and it is easy to fall off the tube, and the exposed catheter joint is easy to be contacted and polluted, causing the risk of infection. At present, gauze is generally used to wrap the catheter joint and fix it with tape, but the gauze is easy to slip off. The patent No. ZL201821055795.6 is made by covering the elastic fabric with a layer of cotton fabric to make a complete body, and a transparent visual window is arranged on the sleeve body, through which the condition of the catheter joint in the sleeve can be observed. Remove and fix the sleeve body, but it cannot be worn during infusion or dialysis, the protective sleeve needs to be removed, and the catheter connector cannot be protected. The patent No. ZL201820482501.1 uses a wire mesh to form the main body of the protective cover. It is not necessary to remove the protective cover during infusion or dialysis operations. The size of the protective cover can be flexibly adjusted through buckles and buckles according to different arm circumferences. This structure is to fix the catheter joint by tying it on the patient's arm. The large area of the strap is easy to cause discomfort to the patient, and the protective cover is open at both ends. exposure to contamination.
