Description

Technical Field

[0001] The utility model relates to the technical field related to medical devices, and in particular to a protective device for a butterfly-wing needle of an infusion port. Background Art

[0002] A butterfly-wing needle is a specialized needle used and maintained for intravenous ports. It comes with an extension tube, a needle tip angled 90 degrees to the handle, and a wing on each side. When using an intravenous port for infusion, the butterfly-wing needle is inserted to establish a central venous access route centered on the injection port. Due to its unique structure, after the butterfly-wing needle is inserted into the port, the two wings lie flat on the skin at the injection port. A transparent dressing secures the wings to the skin, and the accompanying extension tube comes into direct contact with the skin, which can easily cause skin discomfort or even damage.

[0003] In clinical practice, padding dressings are routinely placed under the wings of the butterfly needle. After the extension tube is placed straight in the extension direction, a transparent dressing is used to secure the butterfly needle, padding dressing, and part of the extension tube. The junction of the extension tube and the transparent dressing is secured with silk tape. This method helps to solve the problems of direct contact between the wings of the butterfly needle and the skin, covering the puncture site, padding dressing, and difficulty in separating the transparent dressing from the butterfly needle. However, the following problems exist in clinical application:

[0004] 1. In clinical applications, it was found that the indentation of the extension tube on the skin can easily cause discomfort to patients and lead to skin damage. The movement of the extension tube can easily lead to loosening and curling of the junction between the extension tube and the edge of the transparent dressing, which weakens the sealing effect and increases the risk of infection.

[0005] 2. Fix the butterfly needle and extension tube with a transparent dressing. The flexibility of the transparent dressing can easily cause the butterfly needle to shift and become loosely fixed. Utility Model Content
