Embodiment Construction

[0056] figure 1 A microarray device configured as a microarray carrier device 10 (hereinafter referred to as carrier 10 ) is shown. figure 1 The carrier 10 includes a carrier housing 14 . Included on the exterior of the carrier housing 14 is an applicator 200 (for example, see Figure 7 ) The circumferential groove 22 of the connecting device.

[0057] At the proximal end 19, the carrier housing 14 includes an access opening 28 (see Figure 2a ), applicator 200 (see for example Figure 7 ) of the plunger 204 (also referred to as a piston) enters the carrier housing through this entry opening (see Figure 2a ) inside 38 or, for example, acts on the carrier housing.

[0058] The access opening 28 is closed towards the environment by a membrane 40 forming part of the sterile barrier 36 . Preferably, the membrane 40 is connected to the carrier housing 14 by means of an adhesive and / or welded connection 41 . The membrane 40 includes a flexible region 46 such that, for exampl...

Abstract

The present invention relates to an applicator (200) for applying a microarray, the applicator comprising: a housing (202); a plunger (204) which is arranged in the housing (202) in a linearly movable manner; a holding device (208) for accommodating the microarray device (10); a pressing element (210) for moving the plunger (204) so as to act on the microarray device (10) housed by the holding device (208); and an actuation device (212) that holds the plunger (204) in the first position and releases the plunger (204) for movement by actuating the actuation device (212). The actuating device (212) has at least two separate actuators (214, 216), in particular mechanical actuators. Only when the at least two actuators (214, 216) are actuated, the plunger (204) is released by the actuation device (212). The invention also relates to an application system (300) having such an applicator (200) and a microarray device (10) and a method for moving a plunger. According to the method, the plunger (204) is held in a first position against a pretension, and the plunger (204) is released by the pretension for movement when at least two individual actuations are performed, at least two actuations must be performed for the release process.

Description

【Technical field】 [0001] The present invention relates to an applicator for administering a microarray. Further, the present invention relates to an application system for administering a microarray. Furthermore, the invention relates to a method for moving a plunger. 【Background technique】 [0002] A microarray comprises a plurality of microneedles which are typically arranged on or attached to a carrier element such as a patch, band-aid or the like. This microarray includes a large number of microneedles. The needles have a small length so that when the microneedles are pressed into the patient's skin, the needles only penetrate the skin to the extent that nerves and blood vessels do not come into contact with the needle tip, if possible. The microneedles contain active ingredients or drugs. The corresponding active ingredient can be applied to the surface of the needle or arranged inside the needle. Preferably, the needles are made of a material that dissolves in the...
