Embodiment Construction

[0016] The antimicrobial compress of the present invention comprises a wound contact layer consisting essentially of a non-adhesive viscous gel having dispersed therein a hydrocolloid, one or more antimicrobial agents and a surfactant having an HLB value greater than 10.

[0017] A viscous gel composed of an elastomeric (preferably triblock) backbone and a substantial amount of non-polar oil or fat is part of the contact layer structure and imparts non-adhesive properties to the dressing, wherein the non-polar oil or fat can At the same time, it is used as a plasticizer and anti-adhesive agent for elastomers. The non-tacky cohesive gels thus produced are very elastic and easily moldable and tear-resistant.

[0018] The elastomer is preferably of high molecular weight SEBS or SEPS type, eg Kraton G1651 sold by SHELL or SEPTON sold by KURARAY. The content of elastomer in the contact layer is 3-8% by weight.

[0019] The elastomer is particularly preferably of the triblock type...

Abstract

The invention concerns an antiseptic compress comprising a contact surface with the wound or burn, consisting of an elastomeric matrix highly plasticized with a non-polar oil or grease, said elastomeric matrix containing a dispersed hydrocolloid. The invention is characterised in that said elastomeric matrix further comprises likewise dispersed at least an antiseptic agent and at least a surfactant whereof the hydrophilic / lipophilic balance (HLB) is higher than 10. The invention is applicable in particular to compresses and dressings.

Description

field of invention [0001] The present invention relates to an antiseptic compress for promoting the healing of infected or susceptible wounds, and a dressing containing the antiseptic compress. Background technique [0002] Dressings that maintain a certain level of moisture on the wound surface are known to facilitate wound healing. Many dressings take advantage of this property, such as "ALGOPLAQUE" sold by Laboratoires URGO or "COMFEEL" sold by COLOPLAST, in which hydrocolloid dispersions are contained in an adhesive hydrophobic matrix; the hydrocolloids in these dressings The particles absorb exudate and maintain a moist environment conducive to healing. However, in highly exudative wounds, this absorption is not sufficient and a collection of body fluid may be observed, which may rapidly form a focus of infection. [0003] Another type of dressing is a tulle gras, which uses fats or oils (such as medicinal petrolatum and paraffin) to form prot...
