APPLICATORS AND METHODS FOR APPLYING A MICRONEEDLE PATCH TO A SKIN OF A SUBJECT, AND MICRONEEDLE PATCHES

A reusable applicator for applying a microneedle patch to a skin of a subject which comprises a base for positioning onto the skin. The base comprises a skin-side end and a holder for holding the microneedle patch in position relative to the skin-side end. Two or more contact parts at the skin-side end can contact the skin. One or more are movable over the skin and away from the other contact 5 parts to stretch the skin at least during penetration of the skin by a microneedle of the patch. The applicator further comprises an interface for an actuator. The actuator actuates in operation a movement of the microneedle patch relative to the skin-side end to penetrate at least into the stratum corneum of the epidermis of the skin with the microneedle. A microneedle patch comprises a skin-adhesive surface for attaching the patch to the skin of a10 subject. The patch has one or more microneedles projecting from the skin-adhesive surface out of the patch. A stiffening body stiffens the patch in at least a parallel direction parallel to the skin-adhesive surface in a region of the skin-adhesive surface which includes the microneedle.
