The present disclosure provides an anti-infective and anti-adhesive wound dressing based on nonspecific adhesion to bacteria, which includes a micron-sized porous membrane with polyolefin contained in its surface and does not contain any bactericide. According to the disclosure, through targeted selection of a material and surface structure of the porous membrane, nonspecific adhesion to the bacteria on the wound surface can be formed by good adaptability of its own surface energy and the structure of the porous membrane to surface energy of the bacteria, preventing the bacteria from penetrating into wound tissues and thus realizing the anti-infection for the bacteria and the anti-adhesion to the wound. Furthermore, no bactericide is required to be added, which not only reduces infection of the wound, but also weakens factors which are not conducive to wound healing, such as aggravation of inflammation caused by bacterial toxin released after bacterial rupture in traditional sterilization mechanisms.

The present invention is intended to provide a gel sheet having a formulation providing an adhesive force on the skin side suitable for the skin (i.e., a gel having a low adhesive force and being able to withstand a tip pressure of a terminal and the like), and concurrently having a sufficient adhesive force against an electrode element on the side opposite to the skin side. The present invention is a gel sheet having a laminated structure of a layer A and a layer B, characterized in that the storage elastic modulus of the layer A at 23° C. and 10 Hz is 12,000 to 40,000 Pa, and the storage elastic modulus of the layer B at 23° C. and 10 Hz is 2,000 to 10,000 Pa.

A method of producing a medical device having a substrate and a hydrophilic polymer layer, including the steps of: pretreating the substrate by placing the substrate in an alkali solution and heating the substrate at a temperature ranging from 50° C. to 100° C.; and heating a solution containing the pretreated substrate, a hydrophilic polymer having an acidic group and a hydroxyalkyl group, and an organic acid at a temperature ranging from 50° C. to 100° C. Provided is a simple method of producing a medical device imparted with hydrophilicity excellent in durability.
