Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a fixing belt for an indwelling needle. Background Art

[0002] Intravenous indwelling needle is also called intravenous cannula needle. The core components include a soft catheter / cannula that can be indwelled in the blood vessel, and a stainless steel puncture guide needle core. When in use, the catheter and the needle core are punctured into the blood vessel together. When the catheter is completely in the blood vessel, the needle core is withdrawn, and only the soft catheter is indwelling in the blood vessel. The extension tube is coiled so that the connector is located above the needle eye side, and then properly fixed with a sterile transparent protective film. The connector that is retained outside is usually fixed with an infusion patch or medical tape, and then infusion treatment is performed, which can effectively reduce the pain caused by repeated venous punctures and the resulting fear of injections.

[0003] However, the existing indwelling needle is only fixed with a transparent dressing or fixed with a gauze band wrapped around it after being fixed with a transparent dressing, which makes the indwelling needle easy to shift or fall off, thus requiring re-puncture. In addition, there is a greater risk of bacterial infection. Therefore, an indwelling needle fixing belt is proposed to solve the above problems. Utility Model Content
