A windowless frame delivered dressing is disclosed which has a conformable backing with a pressure sensitive adhesive coated on a bottom face and a low adhesion coating on a top face. The backing is supported during shipping and handling by a liner attached to the adhesive and a removable heat sealed frame attached to the top face of the backing. The method according to the present invention discloses the steps of forming and removing windows in a carrier material and heat sealing the carrier to the backing to form the windowless frame delivered dressings of the present invention.

L'invention concerne un pansement distribué avec cadre sans fenêtre constitué d'une couche dorsale épousant la forme du corps, recouverte d'un adhésif de contact sur la face inférieure et d'un revêtement peu adhésif sur la face supérieure. Ladite couche dorsale est supportée, au cours du transport et de sa manipulation, par une doublure fixée à l'adhésif et un cadre thermosoudé fixé sur sa face supérieure. Le procédé selon l'invention consiste à former des fenêtres dans un matériau porteur, à les enlever, et à thermosouder ledit porteur à la couche dorsale de manière à former les pansements à cadre sans fenêtre selon l'invention.
