Description

Protective bag for long-term indwelling catheter of deep vein

Technical Field

The utility model relates to a protection bag for a long-term indwelling catheter of a deep vein, belonging to the technical field of medical consumable design.

Background

At present, the prevalence rate of End Stage Renal Disease (ESRD) in China is increased year by year, under the condition of shortage of renal sources, people using renal replacement therapy increase year by year, and the survival time of patients using renal replacement therapy is obviously prolonged due to the maturity of hemodialysis technology. For renal replacement therapy patients, deep vein indwelling catheters are required for vascular access for hemodialysis prior to dialysis treatment. A deep vein indwelling catheter is usually left for a long time [ a temporary deep vein indwelling catheter is generally left for 1 week to one month, and a semi-permanent deep vein indwelling catheter is left for 3 months or more ], and therefore the deep vein indwelling catheter needs to be fixed properly.

At present, the method for fixing the deep vein indwelling catheter in clinic is shown in fig. 7 and 8, a sterile application 5 is used for fixing the opening of the catheter 6, then gauze 7 is used for wrapping a bifurcation joint 8 (namely an arteriovenous end of the catheter 6) exposed outside the sterile application 5, and finally an adhesive plaster is used for fixing the wrapped bifurcation joint 8 on the skin. This method of fixation has the following drawbacks: firstly, as the diameter of the indwelling catheter 6 is about 0.5cm, the diameter of the bifurcated joint 8 is about 1cm, the conventional sterile application 5 can not be completely adhered to the skin, a gap of about 1.5cm is usually formed between the conventional sterile application 5 and the skin, and the gauze 7 wrapped at the lower end can not cover the conventional sterile application, namely the wrapped gauze 7 is not tightly connected with the sterile application 5 at the opening of the catheter 6, so that the catheter 6 is easily infected; secondly, the gauze 7 is not tightly wrapped and easily falls off to cause pollution, has potential safety hazard and also influences the beauty; if the gauze 7 is wrapped too tightly, the gauze is difficult to open when dressing change is performed next time; thirdly, as the gauze 7 can not prevent moisture, the gauze 7 can be wetted when the skin around the catheter 6 is cleaned or the patient sweats, and the catheter 6 is easily polluted; fourthly, the fixing method is relatively complicated to operate, and wastes time and labor.
