Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, specifically to a protective cover for indwelling needles. Background Technology

[0002] An indwelling needle is a medical device that leaves a venous access in a patient's vein. It can reduce the pain caused by repeated punctures and is suitable for patients who need long-term infusion. The venous access can be opened at any time to administer medication as early as possible and improve the success rate of rescue.

[0003] Protective covers are suitable for all indwelling needle usage scenarios and locations, but existing protective covers have a single fixing method. At the same time, protective covers lack necessary fixing measures for the infusion extension tubing of the indwelling needle, which can easily cause accidental contact with the indwelling needle.

[0004] During intravenous infusion, accidental contact with the indwelling needle can cause pain to the patient and there is a risk of the needle moving, which can make the infusion difficult. If the needle moves and gets close to the blood vessel wall, the medication can irritate the vessel wall, and the infusion may even cause ulceration and necrosis of the skin tissue.

[0005] After the infusion is completed, the patient can move around freely without being restricted in their movement due to concerns about touching the indwelling needle. The protective cover provides comprehensive protection for the indwelling needle site and surrounding area both during and after the infusion. Utility Model Content
