Abstract
An adhesive composition having dispersed therein a broad spectrum antimicrobial agent for use in medical applications, such as an adhesive for surgical drapes, wound dressings and tapes. The adhesive is composed of acrylic polymers, tackifiers and a preferred antimicrobial agent, diiodomethyl-p-tolylsulfone. The adhesive composition is essentially solventless and capable of application in a hot melt process while maintaining stability at elevated temperatures in the range of 275° F. to 350° F., which not only allows hot melt application, but allows for ethylene oxide sterilization under heat stress.
Claims4
A wound dressing comprising a layer comprising a wound contacting portion and a wound periphery portion adjacent said wound contacting portion, a coating of an adhesive composition overlying at least a portion of said wound periphery portion, said adhesive composition being hot melt applied to said layer and comprising an acrylic polymer having an effective amount of diiodomethyl-p-tolylsulfone dispersed throughout said adhesive composition, said acrylic polymer having a melt temperature between about 275° F. and about 350° F.
