1. An applicator for applying a microneedle device to a skin surface, the applicator comprising:
- a microneedle device having a first side comprising a microneedle array and a second side opposite the first side, the first side configured to be positioned toward the skin surface;
a housing having a first surface configured to be positioned toward the skin surface; and
a connecting member positioned to couple the microneedle device to the housing and configured to allow the microneedle device to move relative to the housing betweena first position in which at least a portion of the microneedle device extends beyond the first surface of the housing, anda second position in which the microneedle device is recessed within the housing, such that the microneedle device does not extend beyond the first surface of the housing,wherein the connecting member is configured to move the microneedle device to the second position when a threshold application force is applied to the first side of the microneedle device in a direction substantially perpendicular with respect to the microneedle device, and wherein the first surface of the housing is not in contact with the skin surface when the microneedle device is in the first position.

Abstract
An applicator (100) for applying a microneedle device to a skin surface. The applicator can include a microneedle device (106), a housing (102), and a connecting member (110). The connecting member can be configured to allow the microneedle device to move between: (i) a first position in which at least a portion of the microneedle device extends beyond the housing; and (ii) a second position in which the microneedle device is recessed within the housing when a threshold application force is applied to the microneedle device in a direction substantially perpendicular with respect to the microneedle device.
