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.
Claims20
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, and extending away from the patch and turning over, and being fixed to the patch application support;
- 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;
- and
- a fork to hold the patch at a given position in relation to the patch application support, wherein the fork comprises two claws to be fitted in the patch application support and a flat part under which an upper side of the first part of the adhesive area is attached directly or via a casting sheet,
- wherein the 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 the at least one pore in the skin surface, the patch application support with the porating element is slidable 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 alignedly cover the porated area.

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, and extending away from the patch and turning over, and being fixed to the patch application support;
- 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;
- a porator backing;
- and
- a porator tab as the patch application support, wherein the porator tab is a band-shaped plate with one end thereof fixed to the porator backing, the porator tab comprising:
- an objective-surface facing outwardly such that, when the device is in use, the objective-surface contacts the skin surface of a subject;
- a back-surface on an opposite side of the objective-surface;
- and
- one or more filaments as the porating element in a porating area in the objective-surface of the porator tab, wherein the one or more filaments are configured to generate heat to form the at least one pore in the skin of the subject, wherein the at least one pore comprises one or more micropores, and
- wherein the 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 the least one pore in the skin surface, the patch application support with the porating element is slidable 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 alignedly cover the porated area,
- wherein, the patch is positioned on the back-surface on the opposite side of the objective-surface, the patch having the adhesive area and a reservoir placed on an adhesive surface of the adhesive area and the reservoir releasably contains a permeant to be delivered through or into the at least one pore, and is alignedly positioned on the back-surface on the opposite side of the objective-surface at a position corresponding to the porating area, with the adhesive surface of the adhesive area facing the skin of the subject.
