Low-Profile Microneedle Patch Applicator

摘要

A low-profile applicator, and a method of manufacturing and use thereof, for impacting microneedles against the stratum corneum of a person having a housing, a diaphragm member having the microneedles, a folding member having interlinking members that hinge-ably rotate with a force member, operatively attached thereto, between a resting position and an extended position. The folding member translates energy stored within the force member when release while retaining the force member in an energized state when in the resting position.

主权项

1. An apparatus for impacting microneedles against the stratum corneum of a person, comprising:
a housing having an opening defining a first plane for impact against the stratum corneum; a diaphragm member disposed within the housing at a second plane substantially parallel to the first plane, the diaphragm member having a plurality of microneedles; a folding member fixably disposed within the housing, the folding member having a plurality of arms, each arm comprising a plurality of interlinking members to hinge-ably rotate between a resting position and an extended position; and a force member operatively attached to the folding member to (i) store energy along a first direction when the plurality of interlinking members is in the resting position and (ii) move the plurality of interlinking members to the extended position when released from the resting position thereby moving the diaphragm member from the second plane to the first plane along a second direction transverse to the first direction, wherein, when released from the resting position, the folding member translates energy stored within the force member to the second direction from the first direction.
