摘要:
An antimicrobial pressure-sensitive adhesive (PSA). The PSA system can include an antimicrobial polymer having a plurality of pendant groups. The plurality of pendant groups can include (i) a first pendant group comprising a nonpolar compound, (ii) a second pendant group comprising a quaternary ammonium compound, and (iii) a third pendant group different from the first pendant group or the second pendent group, wherein the third pendant group provides inter-reactivity, such that the antimicrobial polymer can include one or more intermolecular interactions. The antimicrobial polymer can be free of non-ionic hydrophilic moieties. The PSA system can have a glass transition temperature Tg ranging from 0 to 50 degrees C.

Disclosed is an apertured hydrogel that is used in connection with an insertion device to provide comfort at the site of entry into the skin. In one embodiment, the hydrogel contains antimicrobial properties to help inhibit microbial growth at the site of insertion of the device into the skin. In the invention the apertured hydrogel is provided with a medical dressing and comprises a hydrogel having an upper surface and a lower surface, a film covering the upper surface of the hydrogel, a base sheet releasably covering to the lower surface of the hydrogel, an aperture in the film and hydrogel from the upper surface to the lower surface of the hydrogel, wherein the base sheet extends beyond the hydrogel to form a tab.
