Description

Technical Field

[0001] The utility model relates to the field of breathable wound dressing, in particular to a butterfly-shaped breathable wound dressing. Background Art

[0002] A bandage is a medical device that is pasted on the wound to protect the wound and prevent infection. It mainly includes a connecting part and a medicinal part. The bandage can compress and stop bleeding, protect the wound surface, prevent infection, and promote healing. At the same time, it has the advantages of small size, simple use, easy to carry, and reliable efficacy. It has become a common medical device. After searching, the prior art (application number: CN202320991139.1) records that "a double cross-section fiber is used by a special-shaped cross-section fiber layer, and a groove is formed on the surface of the double cross-section fiber, and the groove is used to form a groove. The wicking moisture-conducting structure, coupled with its relatively fluffy yarn structure, greatly increases the air permeability of the profiled cross-section fiber layer, which can quickly absorb moisture generated on the surface of human skin and discharge the moisture through the profiled cross-section fiber layer, thereby enhancing the air permeability of the bandage, thereby avoiding the situation where the skin wrapped inside the bandage is in a humid environment, causing the local skin to turn white, preventing wound infection, and keeping the skin wrapped by the bandage dry. However, the moisture conductivity of the profiled cross-section fiber layer of the bandage in the prior art is limited, and it needs to be replaced when it is wet, which affects the normal daily use of the wound adhesive wearing part. Utility Model Content

[0003] In order to overcome the defects of the prior art, a butterfly-shaped breathable bandage is now provided to solve the problem that the special-shaped cross-section fiber layer of the bandage in the prior art has limited moisture conductivity and needs to be replaced when it gets wet, which affects the normal daily use of the wound adhesive wearing part.

[0004] To achieve the above object, a butterfly-shaped breathable wound patch is provided, comprising: a butterfly-shaped wound patch body, an adhesive inner layer and a drug absorption pad, wherein the inner layer of the butterfly-shaped wound patch body is provided with an adhesive inner layer, and the drug absorption pad is bonded to the middle of the adhesive inner layer.

[0006] Furthermore, the butterfly-shaped wound dressing body is composed of a breathable frame, a waterproof outer film layer, a non-woven fabric layer, an adhesive inner layer and a drug absorption pad.

[0007] Furthermore, a waterproof outer film layer made of polyethylene is pasted on the upper surface of the non-woven fabric layer, and a rectangular notch is opened in the middle of the waterproof outer film layer; and the rectangular notch of the waterproof outer film layer is located on the inner side of the air permeable frame.

[0008] Furthermore, the air permeable cavity wall is bonded with resilient sponge strips at equal intervals, and a waterproof adhesive layer is provided on the outer side of the bonding inner layer.

[0009] Furthermore, a breathable fiber interlayer is arranged between the adhesive inner layer and the drug absorption pad; and the breathable fiber interlayer is glued to the lower surface of the non-woven fabric layer.

[0010] Furthermore, the lower end of the water blocking plug is bonded to the waterproof outer film layer through a rebound sponge support, and the side wall at the air vent is provided with anti-stripping lines.

[0011] Furthermore, the air permeable frame, the air permeable cavity, the air permeable port, the water blocking plug and the rebound sponge support constitute a switchable air permeable structure of the butterfly-shaped wound dressing body.

[0012] The beneficial effect of the utility model lies in that the butterfly-shaped breathable band-aid of the utility model is bonded to the top of the drug absorption pad of the band-aid by a breathable frame, and the rebound sponge pillar supports the water-blocking plug to be separated from the breathable opening of the breathable frame, so that the air around the drug absorption pad can flow in the breathable frame, and the breathable opening can be closed or opened by pressing or pulling out the water-blocking plug, thereby realizing a switchable breathable structure, making it convenient for the butterfly-shaped breathable wound to get wet or touch water, while accelerating the air circulation effect of the skin on the wound side, enhancing the breathability of the butterfly-shaped breathable band-aid, ensuring that the butterfly-shaped breathable band-aid does not affect normal daily activities when being pasted, and improving the practicality of the butterfly-shaped breathable band-aid.
