Abstract
An applicator and method for applying a microneedle array to skin. The applicator can include a body having a first portion and a second portion defining a cavity, the second portion having a slot presented on an outside surface for insertion of the microneedle array into the cavity. The first portion and the second portion are slidable relative to one other along an axis enabling the body to be in an unprimed configuration and a primed configuration. The applicator further includes a door operable with the second portion, the door being movable from a first door position to a second door position, wherein when the device is in the unprimed configuration, the door at least partially obstructs the slot and access into the cavity. When the device is in the primed configuration, the door does not obstruct the slots and enables access into the cavity.
Core Innovation
A microneedle array applicator for skin includes a body having a first portion and a second portion that define a cavity. The second portion includes a slot presented on an outside surface for insertion of the microneedle array into the cavity, and the first portion and the second portion are slidable relative to one another along an axis to enable an unprimed configuration and a primed configuration.
The applicator includes a plunger disposed in the cavity. The plunger has a first plunger end and a second plunger end and moves from a first position when the device is in the unprimed configuration to a second position when the device is in the primed configuration. In the primed configuration, the microneedle array is adapted to be inserted into the cavity through the slot and positioned proximate the second plunger end.
When the device is in the primed configuration, the plunger is adapted to contact the microneedle array when the first portion and the second portion of the body are axially compressed but before the plunger is released. The arrangement includes friction reduction by using low surface energy material on an inner surface and includes user alignment indicia associated with the slot.
Claims Coverage
The independent claims cover 3 inventive features centered on a microneedle array applying device with a slidable body, an insertion slot, and a plunger that provides defined unprimed and primed configurations.
Slidable body defining cavity and slot for microneedle insertion
A body comprising a first portion and a second portion defining a cavity, wherein the second portion comprises a slot presented on an outside surface for insertion of the microneedle array into the cavity, and the first portion and the second portion are slidable relative to one another along an axis to enable an unprimed configuration and a primed configuration.
Plunger movable between unprimed and primed configurations
A plunger disposed in the cavity, the plunger comprising a first plunger end and a second plunger end, the plunger movable from a first position when the device is in the unprimed configuration to a second position when the device is in the primed configuration.
Positioning and contacting microneedle array proximate the second plunger end before release
When the device is in the primed configuration, the microneedle array is adapted to be inserted into the cavity through the slot and positioned proximate the second plunger end, and the plunger is adapted to contact the microneedle array when the first portion and the second portion of the body are axially compressed but before the plunger is released.
The inventive subject matter centers on a slidable body forming a cavity and externally presented slot for microneedle insertion, combined with a plunger that changes between unprimed and primed configurations to position and contact the microneedle array proximate the second plunger end before release.
Stated Advantages
