摘要:
An ultra thin film transdermal, dermal, transmucosal, mucosal pharmaceutical delivery system is disclosed, which has a handle adhered by a first adhesive to an ultra thin film layer. The opposite side of the ultra thin film is coated with a second adhesive layer, and carries an active ingredient. The handle adheres firmly to the ultra thin film layer, but does not adhere to skin, mucosa, or the silicone coated surface of a release liner. A portion of the handle extends beyond an edge of the ultra thin film to facilitate separation of the film from the release liner, and handling thereof. The second adhesive is more aggressive with respect to the patient's skin than the first adhesive is with respect to the surface of the ultra thin film, whereby the handle can be peeled away from the ultra thin film after the film has been applied to the patient.

A wound dressing includes a transparent vapor and gas permeable polymeric film which has an adhesive coated surface. A pair of liners or release sheets cover the adhesive coated surface and the liners define overlapping gripping flaps. Additional adhesive strips are positioned at opposed edges of the film and interposed between the adhesive coated surface of the film and the liners. Increased adhesion of the film to the liners occurs at the adhesive strips. The film is perforated adjacent the adhesive strips.
摘要:
A machine and method for making base assemblies for medicine dispensing compresses, includes using a web of substantially imperforate material, and a web of backing material having a base layer with an adhesive on one side to attach the compress to the skin of the user. A plurality of individual foil lids or dam patches are cut from the web of imperforate material, and applied to the adhesive side of the base layer. A release or cover layer is applied to the adhesive side of the base layer to sandwich the dam patches between the base layer and the cover layer. Individual base units are cut into the base layer, with one of the dam patches positioned within each of the base units. Apertures are cut in the areas of the cover layer overlying the dam patches to access a portion of the foil surface of each of the dam patches. The offal portion of the base layer is removed from the cover layer, forming fabricated base assemblies for the compresses, which are conveniently carried together on the cover layer for final assembly. The dam patch cutting and applying steps may include roller die cutting the web of imperforate material, separating the dam patches from the offal portion by a vacuum operated applicator drum, and pressing the cut dam patches into contact with the adhesive side of the base layer. For final assembly of the compresses, a medicine-filled pad is positioned on each of the dam patches, and an imperforate, removable outer sheet is applied over each of the medicine-filled pads to form sealed reservoirs in which the medicine-filled pads are retained.
