[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The support structure of the utility model can effectively prevent the wound dressing from being deformed during storage, thereby effectively ensuring the convenience of taking and placing the wound dressing;

[0015] 2. The setting of the arc-shaped support strip in the utility model can effectively support the dressing body. At the same time, the setting of the arc-shaped connecting strip can prevent the arc-shaped support strip from being deformed. The setting of the antibacterial layer can ensure the antibacterial ability of the wound dressing. The setting of the waterproof layer can improve the waterproof effect of the wound dressing.
