Abstract
Embodiments of the present disclosure relate to techniques, processes, devices or systems including a floating microneedle assembly decoupled from the device and protected by a pump housing. In one approach, a wearable drug delivery device may include a pump housing including a base attachable to a user, and a microneedle assembly coupled to a cannula. The microneedle assembly may be operable to deliver a liquid drug to the user, wherein the microneedle assembly comprises a carrier positioned proximate an opening of the base, and wherein the carrier comprises a plurality of microneedles operable to extend through the opening of the base to penetrate a skin of the user.
Claims7
A microneedle assembly of a wearable drug delivery device, the microneedle assembly comprising:
- a carrier coupled to a cannula;
- a microneedle housing surrounding the carrier and comprising a snap-fit tab operable to engage the carrier to maintain a position of the carrier relative to a user, wherein the microneedle housing and the carrier are decoupled from one another, wherein in a deployed configuration the microneedle housing constrains the carrier only in a direction away from the user and provides lateral clearance within a recess to reduce transfer of upward and lateral forces from the housing to the carrier;
- and
- a plurality of microneedles extending from the carrier, the plurality of microneedles operable to:
- receive a liquid drug from the cannula;
- and
- penetrate a skin of the user to deliver the liquid drug to the user when the carrier is biased relative to the microneedle housing.
