Definitions
- the invention relates to a carrier for at least one microarray and a method for producing a carrier for at least one microarray.
- Microarrays have a large number of microneedles, which are usually arranged on a carrier element, such as a patch, a plaster or the like, or are connected to a carrier element. Such microarrays have a high number of microneedles, for example 500-600 needles per cm 2 .
- the needles have a short length, so that when the microneedles are pressed into the skin of a patient, the needles only penetrate into the skin to such an extent that nerves and blood vessels are not touched by needle tips.

- microneedles of the micro arrays There are also problems with regard to the microneedles of the micro arrays. These are susceptible to physical influences, which can damage and ultimately lead to failure of the microneedles. Since microneedles are often made soluble, the needles are also damaged in contact with liquids or vapors. Furthermore, unintended injection of people, for example medical personnel, can occur with exposed microneedles.

- the release device 30 is preferably designed as a target force release.
- the stamp is only released when at least one target force is applied, preferably when at least one target force is applied to the stamp.
- the target force trigger can preferably be designed such that the at least required target force corresponds to an, in particular optimal, application force for puncturing and applying the microarray 12.
- the target force release is accomplished in particular via the releasable form fit between groove 29 and bead 31.
- FIG. 3 shows a further embodiment of a carrier 10 according to the invention. The embodiment shown is essentially similar to the embodiment from FIG. 2a.
- the release device 30 of the embodiment from FIG. 3 is a fit, particularly an oversize fit, between the stamp 16 and the housing 14. Because of the fit, the stamp is thus initially held in the starting position. After the stamp 16 has been deflected, the fit likewise performs the function of the holding device 32 and thus ensures that the stamp is fixed in the application position.
- the connecting device 20 has a thread 24, with which, for example, a correspondingly opposite thread of an applicator can be connected.
- the embodiment from FIG. 3 does not have a blister, but a film 44.
- the film 44 is connected to the housing 14 at the distal end 17, in particular via an adhesive layer 41.
- the foil 44 can be pulled off and removed by a user via the illustrated foil tab 47.
- the adhesive layer 41 is connected to the housing 14 at the distal end 17, in particular via an adhesive layer 41.
- the foil 44 can be pulled off and removed by a user via the illustrated foil tab 47.
- FIG. 4 shows a further embodiment of a carrier 10 according to the invention.
- the embodiment is similar to the embodiment from FIG. 3, with the differences described below.
- the embodiment has a blister 42, which completely encloses the housing 14 radially. At the proximal end 17, the housing 14 lies on one of the blisters
- the housing 14 has an adhesive layer 34 on the distal end 17, which is located radially further inward and which represents a fixing device for fixing the carrier 10 at an application site.
- the ad adhesive layer 34 does not come into contact with blister 42, but is spaced therefrom.
- the blister 42 forms a type of guide shape at the proximal end, for example for an applicator.
- An applicator can thus be inserted, for example, into the blister and then connected to the connecting device 20, which is shown as a plug connection. Subsequently, it is possible for the blister 42, which is preferably only attached to the housing 14, to be removed. Subsequently, an application based on the embodiments described above can be carried out.
- FIGS. 5a and 5b show a further embodiment of a carrier 10 according to the invention.
- the embodiment has no holding device.
- the stamp 16 and the housing 14 are no longer connected to one another or are loosely connected to one another. As a result, the punch 16 and housing 14 can be moved relative to one another.
- FIG. 5 b accordingly shows a removal of the housing 14 from the application site 100, the stamp 16 with the applied microarray remaining on the application site 100.
- the sterile barrier 36 shown has the film 40.
- the film 40 bulges from the distal end 17 of the housing 14 through the application opening 18 and encloses the stamp 16 towards the access opening 28.
- the interior of the housing 38 or the microarray 12 is sterile.
- the film 40 preferably has an adhesive layer 39 distally, so that, as shown in FIG. 5b, the film 40 can be connected to the application site 100.
- the, in particular elastic, film 40 can be used, on the one hand, for pressing the microarray 12 into the application site 100 and / or for sterility to the environment.
- the illustrated embodiments of the carrier 10 are rotationally symmetrical about the axis of rotation 50.
- another version for example cuboid, is also possible.
- the step of connecting the microarray to the stamp takes place by means of a stamp according to the embodiments shown in FIGS. 1 to 4.
- the carrier 10 is preferably brought into contact with the distal end of the stamp 16 with a patch 13 of a microarray 12 before a blister 42 or a film 44 is attached.
- the microarray 12 is preferably located in a mold used to manufacture the microarray.
- the patch 13 of the microarray 12 and / or the distal end of the stamp 16 in particular have an adhesive layer, so that after the stamp 16 and the microarray 12 have been brought into contact, there is an adhesive connection between them.
- the microarray 12 can then be removed from the mold via the carrier 10. As a result, the microarray 12 is preferably removed from the mold by means of carrier 10.
- FIG. 6 shows a further embodiment of a carrier 10.
- the embodiment shown here essentially corresponds to the embodiment from FIG. 2a.
- the stamp action surface 60 of the stamp 16 from FIG. 6 is not flat, but is designed as a conical indentation, also to be referred to as a negative cone shape.
- a conical indentation also to be referred to as a negative cone shape.
- a pyramid-shaped or partially spherical indentation is also possible.
- the conical indentation of the stamp action surface 60 from FIG. 6 advantageously has the effect that, for example, an applicator stamp with a correspondingly positive conical shape can strike the stamp action surface 60 and thus an optimal force transmission is provided.
