Embodiment Construction

[0027] Figures 1 to 7 A device 10 is shown having a positioning frame 20 , an active ingredient unit 60 comprising a transdermal therapeutic system 61 and a tool unit 40 . figure 1 The device is shown here before embedding, with the storage and transport protection removed. In this plan view, the active ingredient unit 60 is located above the positioning frame 20 and the tool unit 40 is located below the positioning frame. In this exemplary embodiment, the active ingredient unit 60 and the tool unit 40 are each connected to the positioning frame 20 by means of a connecting web 41 , 62 , which is formed, for example, as a film hinge.

[0028] positioning frame 20 in figure 1 The top view of is a rectangular frame with constant thickness. This thickness is for example less than three millimeters. The positioning frame 20 is made of elastically deformable material. This can be plastic, such as a polymeric material. The positioning frame can be made of one or more component...

Abstract

The invention relates to a device with a positioning frame that can be adhered to the skin and with a transdermal therapeutic system that can be embedded in a cavity penetrating the positioning frame, wherein the active ingredient feed of the embedded transdermal therapeutic system The feeding side faces the skin. The device comprises a tool unit which can be inserted into and centered in a cutout of the positioning frame for producing a breach at least in the uppermost layer of the skin. The delivery of active ingredients in transdermal therapeutic systems is improved by means of the invention.

Description

technical field [0001] The invention relates to a device with a positioning frame that can be adhered to the skin and with a transdermal therapeutic system that can be embedded in a cavity penetrating the positioning frame, wherein the active ingredient feed of the embedded transdermal therapeutic system The feeding side faces the skin. Background technique [0002] A device of the same type is known from WO 2006 / 131931 A2. Active ingredient application may be prevented or impeded by the barrier properties of the skin. Contents of the invention [0003] The technical problem to be solved by the present invention is to improve the delivery of active ingredients in transdermal therapeutic systems. [0004] This technical problem is solved by means of a device having a positioning frame that can be glued to the skin and having an active ingredient unit with a transdermal therapeutic system having an active ingredient container, the active ingredient container Arranged to b...
