Title
(EN) SURGICAL DRESSING WITH DELIVERY SYSTEM AND METHOD OF MANUFACTURE
(FR) PANSEMENT CHIRURGICAL A SYSTEME DE DISTRIBUTION, ET SON PROCEDE DE FABRICATION
Abstract
(EN) Adhesive composite dressings (10, 110, 210, 310) with delivery systems and methods of manufacturing the dressings are disclosed. The dressings (10, 110, 210, 310) include liners (16, 116, 216a and 216b, 316a and 316b) having a release surface (15, 215a and 215b, 315a and 315b) and a retention surface (19, 219a). The bond strength between the liner (16, 116, 216a and 216b, 316a and 316b) and the pressure sensitive adhesive (14, 114, 214, 314) in the area of the retention surface (19, 219a) is greater than the bond strength between the liner (16, 116, 216a and 216b, 316a and 316b) and the pressure sensitive adhesive (14, 114, 214, 314) in release surface (15, 215a and 215b, 315a and 315b). The increased bond strength in the area of the retention surface allows the backing (12, 112, 212, 312) to be held taut during delivery to assist in smooth aseptic delivery of the dressing (10, 110, 210, 310). The retention surfaces can be provided by abrasion, embossing, perforating the liner, or combinations thereof.
(FR) L'invention concerne des pansements adhésifs composites (10, 110, 210, 310) comprenant des systèmes de distribution, et leurs procédés de fabrication. Lesdits pansements (10, 110, 210, 310) comportent des garnitures (16, 116, 216a et 216b, 316a et 316b) possédant une surface de libération (15, 215a et 215b, 315a et 315b) et une surface de retenue (19, 219a). La résistance d'adhésion entre la garniture (16, 116, 216a et 216b, 316a et 316b) et l'adhésif auto-collant (14, 114, 214, 314) dans la zone de la surface de retenue (19, 219a) est supérieure à la résistance d'adhésion entre la garniture (16, 116, 216a et 216b, 316a et 316b) et l'adhésif auto-collant (14, 114, 214, 314) dans la surface de libération (15, 215a et 215b, 315a et 315b). La résistance d'adhésion accrue dans la zone de la surface de retenue permet à la bande de support (12, 112, 212, 312) d'être maintenue raide pendant la distribution, afin de permettre une distribution aseptisée et sans à-coup du pansement (10, 110, 210, 210). Les surfaces de retenue peuvent être produites par abrasion, gaufrage, perforation de la garniture, ou par des combinaisons de ces opérations.
