DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0018] Please refer to Figures 1 to 4 , in the embodiment of the present utility model, a butterfly breathable wound dressing includes a wound dressing adhesive layer 1, a pressing mechanism is arranged at the top of the wound dressing adhesive layer 1, and the pressing mechanism is used to assist in pressing and hemostasis for the puncture needle hole; the pressing mechanism includes a fixing box 2 fixedly connected to the top of the wound dressing adhesive layer 1, the bottom end of the fixing box 2 is of an open structure, a pressing plate 9 is slidably connected up and down on the inner wall of the fixing box 2, an elastic member 13 is fixedly connected between the top end of the pressing plate 9 and the top end of the inner wall of the fixing box 2, a rotating column 12 penetrating above the pressing plate 9 is fixedly connected to the top end of the pressing plate 9, and two symmetrically arranged limiting plates 11 are integrally formed on the outer periphery of the rotating column 12.
[0019] In this embodiment: First, after puncturing a blood donor or a patient with an infusion needle, the wound patch adhesive layer 1 is pasted on the puncture position. After blood donation or infusion is completed, by rotating the connecting plate 5, the connecting plate 5 drives the two limiting plates 11 on its outer periphery to rotate. When the misaligned limiting plate 11 is opposite to the square groove 10, at this time, the elastic member 13 resets, and the elastic member 13 pushes the pressing plate 9 downward. The pressing plate 9 contacts the top of the wound patch adhesive layer 1 and applies a squeezing force downward, applying a downward pressure to the puncture opening to assist in hemostasis, avoiding the unrestricted overflow of blood from the puncture hole, thereby reducing the amount of bleeding.
[0020] Please refer specifically to Figure 4 , a downwardly concave circular hole 4 is formed in the top plate of the fixed box 2, and two downwardly concave square grooves 10 are formed in the top plate of the fixed box 2. The two square grooves 10 are symmetrically arranged, and one end of the two square grooves 10 close to each other is communicated with the circular hole 4.
[0021] In this embodiment: The circular hole 4 allows the rotating column 12 to move up and down. When the square groove 10 is misaligned with the limiting plate 11, at this time, the limiting plate 11 cannot move downward. By rotating the connecting plate 5, the connecting plate 5 drives the limiting plate 11 to be misaligned with the square groove 10. At this time, the limiting plate 11 is no longer restricted, and the reset of the elastic member 13 can be realized.
[0022] Please refer specifically to Figure 2 and Figure 3 , a hemostatic cotton 6 is provided at the center of the bottom end of the wound patch adhesive layer 1. A first release layer 7 is pasted on one side of the bottom end of the fixed box 2, and a second release layer 8 is pasted on the other side of the bottom end of the fixed box 2. The first release layer 7 and the second release layer 8 are used to protect the hemostatic cotton 6.
[0023] In this embodiment: After puncture, by tearing off the first release layer 7 and the second release layer 8, the adhesive surface of the wound patch adhesive layer 1 is attached to the puncture position, and the hemostatic cotton 6 is located at the puncture hole position.
[0024] Please refer specifically to Figure 3 and Figure 4 , arc-shaped notches 3 are formed at one ends of the wound patch adhesive layer 1, the first release layer 7, and the second release layer 8, and notches 14 are formed at both ends of the fixed box 2.
[0025] In this embodiment: The setting of the arc-shaped notch 3 can reduce the overlapping position of the wound patch adhesive layer 1 and the infusion needle. After blood drawing or infusion is completed, it is convenient to pull out the infusion needle more easily, thereby preventing the problem of obstruction when pulling out the infusion needle. It should be noted that: the material of the wound patch adhesive layer 1 is made of a semi-permeable membrane adhesive material, which facilitates the realization of the air permeability effect.
[0026] When the elastic member 13 is in a compressed state, the restoring force of the elastic member 13 acts on the top of the wound dressing adhesive layer 1 through the fixing box 2, and thus acts on the human body. The opening of the notch 14 can prevent the force of the fixing box 2 from acting on the punctured vein and avoid affecting blood drawing and infusion.
[0027] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent replacements or changes should be covered within the protection scope of the present invention.
