Embodiment Construction

[0146] The invention is explained below by means of preferred embodiments.

[0147] Such as Figure 4 As shown, the transdermal drug delivery device of the present invention (hereinafter also referred to as a device) includes at least a patch drug delivery carrier 420A, a patch 300 and a middle release liner 330 . exist Figure 4 In the embodiment, preferably, the patch administration carrier 420A has a flat plate shape, especially preferably, a fin-shaped flat plate, a strip plate or a strip plate. exist Figure 4 In this case, the patch 300 includes an adhesive sheet 310 and a liquid reservoir layer 320 on an adhesive area (adhesive surface) 310 a of the adhesive sheet 310 . However, the patch may be a single sheet like a plaster. Such as Figure 7 As shown, the patch 300 has an adhesive area 310 a having a first portion 312 and a second portion 314 . When the patch 300 is a single sheet and has no surface reservoir, in Figure 7 , the region of the reservoir layer 32...

Abstract

The device of the invention comprises, as a common characteristic feature, an intermediate release liner covering a part of the adhesive surface of the patch. The intermediate release liner is remote from the patch and is secured to the patch administration carrier (or punch tab). Due to this configuration, in the state of use where the first part of the adhesive area of ​​the patch is adhered to the skin surface, the patch administration carrier slides along the skin surface, and at the same time, the intermediate release liner is released from the patch adhered to the skin surface. The part of the adhered area of ​​the sheet is peeled off.

Description

technical field [0001] The present invention relates to devices for the transdermal administration or delivery of penetrants through biological membranes or the skin of a subject. More specifically, the present invention relates to a transdermal drug delivery device having a novel positioning mechanism that enables better placement of the patch at a target area on the surface of the subject's skin, or on the subject's skin The target perforation area formed by the perforator (the area surrounding the many micropores formed on the skin). According to its embodiment, the device may be referred to as a transdermal drug delivery or delivery system. Background technique [0002] The stratum corneum is the outer stratum corneum of the skin and is primarily responsible for the skin's barrier properties. Thus, it is this layer that constitutes the greatest barrier to the transdermal flux of drugs or other molecules into the organism and to the transdermal flux of analytes outside ...
