    Abstract: A minus-pressured bandage includes a coverage layer, a minus-pressed acting member, an adhering layer and a fixing tap. The coverage layer includes a through-hole to be connected to a minus-pressured device. The minus-pressed acting member includes a fixed-shaped layer and a contact layer abutting with the fixed-shaped layer. The contact layer is made of a resilient material. The fixed-shaped layer has hardness greater than that of the contact layer. Each of the fixed-shaped layer and contact layer has a plurality of first absorbing holes and a plurality of second absorbing holes aligned with the first absorbing holes. The adhering layer is porous and abuts between the coverage layer and the fixed-shaped layer. The fixing tap is arranged on the coverage layer in order to fasten the minus-pressured bandage on the wound. In this arrangement, a minus-pressured suction applied to the wound may be increased to facilitate capillary angiogenesis.
