[0024] In this embodiment, if Figure 1 As shown, a patch for butterfly needles comprises an upper layer 1 and a lower layer 3, the lower surfaces of the upper layer 1 and the lower layer 3 are both provided with an adhesive layer, a notch 4 is provided on the lower layer 3, and an easy-tear mechanism is provided on the upper layer 1, and the easy-tear mechanism is located above the notch 4. By providing the notch 4 on the lower layer 3, when the medical staff inserts the butterfly needle into the skin, the medical staff sticks the lower layer 3 around the puncture point so that the needle tube is located in the notch 4, thereby ensuring that the lower layer 3 and the skin can be fully attached to protect the puncture point. After the attachment is completed, the upper layer 1 is attached to the upper surface of the lower layer 3 so that the wings of the butterfly needle are located below the easy-tear mechanism. When the needle needs to be removed, the medical staff tears the easy-tear mechanism and then removes the butterfly needle, thereby facilitating the removal of the butterfly needle and avoiding injuries to the medical staff.

[0025] Further, such as Figure 2 As shown, the notch 4 is located in the middle of the lower layer 3, the lower surface of the lower layer 3 is provided with an adhesive layer a5, the middle of the adhesive layer a5 is provided with a notch 11, and the notch 11 is located below the notch 4. Specifically, the main function of the notch 11 is to prevent the adhesive layer a5 from sticking to the needle tube, which would affect the subsequent removal of the butterfly needle.

[0026] In this embodiment, if Figure 3 As shown, the easy-tear mechanism includes a cover plate 7, an operation port 6 is provided in the middle of the upper layer 1, a cover plate 7 is provided above the operation port 6, and a plurality of easy-tear strips 8 are provided at equal intervals between the side of the cover plate 7 and the operation port 6, that is, the side of the cover plate 7 and the operation port 6 are connected by a dotted line, and can be torn apart by applying a small force. Furthermore, a handle strip 9 is provided on the upper surface of the cover plate 7. Preferably, as Figure 4 As shown, the hand-held strip 9 is L-shaped. Specifically, the L-shaped hand-held strip 9 can prevent the upper end of the hand-held strip 9 from scratching the medical staff. Furthermore, the length of the cover plate 7 is greater than the length of the operating port 6. Specifically, the lower layer 3 is attached around the puncture point so that the needle tube is located in the notch 4, and then the upper layer 1 is attached to the upper surface of the lower layer 3 so that the wings of the butterfly needle are located in the operating port 6, and the cover plate 7 is located above the wings. The length of the cover plate 7 is greater than the length of the operating port 6, which can effectively prevent air dust from falling into the puncture point. When the needle needs to be removed, the medical staff pulls the hand-held strip 9 and applies force upward to break the easy-tear strip 8, thereby tearing off the cover plate 7, exposing the wings of the butterfly needle to the operating port 6, making it easier to remove the butterfly needle and avoiding injuries to the medical staff.

[0027] In this embodiment, the lower surface of the upper layer 1 is provided with an adhesive layer b2, and a notch b10 is provided in the middle of the adhesive layer b2, and the notch b10 is located below the operation port 6. Specifically, the notch b10 is mainly used to prevent the adhesive layer b2 from sticking to the wings of the butterfly needle, so that the wings of the butterfly needle are exposed in the operation port 6 after the cover plate 7 is torn off.

[0028] Furthermore, the four ends of the upper layer 1 and the lower layer 3 are all arc chamfered structures. Specifically, the main function of the four ends of the upper layer 1 and the lower layer 3 being arc chamfered structures is to avoid scratches to medical staff.

[0029] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein.
