Abstract
The device of the present invention comprises an intervening release liner as a common special feature, and the intervening release liner covers a part of an adhesive surface of a patch. The intervening release liner gets away from the patch, and is fixed to a patch application support (or porator tab). Due to such constitution, under a situation in use where the first part of the adhesive area of the patch adheres to a skin surface, the patch application support is slidable along the skin surface while peeling the intervening release liner from said part of the adhesive area of the patch to adhere to the skin surface.
Claims19
A transdermal permeant application device comprising
- a patch application support;
- a patch having an adhesive area, the adhesive area having a first part and a second part;
- and
- an intervening release liner provided between the patch application support and the patch, the intervening release liner covering the second part of the adhesive area of the patch, extending away from the patch and turning over in a curl configuration around and away from the patch to facilitate a smooth rolling peel of the intervening release liner, and being fixed to the patch application support, wherein the intervening release liner is configured not to contact and adhere to the skin during a porating process;
- wherein the transdermal permeant application device further comprises:
- a porating element, wherein the porating element is provided in or on the patch application support, and the porating element is adapted to form at least one pore in a skin surface;
- wherein the transdermal permeant application device is configured so that, in a use situation in which the first part of the adhesive area of the patch adheres to the skin surface, and the porating element forms at least one pore in the skin surface, the patch application support with the porating element is slidable along the skin surface without lifting along the skin surface to peel the intervening release liner from the second part of the adhesive area of the patch, to adhere the second part to the skin surface and allow the patch to be positioned over a porated area.
