Abstract
A device for providing a droplet of a liquid stored in an interior of a vial is disclosed that includes a support body and a resilient dome portion mounted to the support body to form a chamber having air, with the dome portion being configured to create an air flow when activated by compression. The support body includes a vial seat, a nozzle, and air flow and transfer conduits. The support body is arranged, when the vial is received by the vial seat, such that the air flow conduit establishes an air connection between the vial interior and the chamber, the transfer conduit establishes a fluid connection between the vial and the nozzle, and, upon activation of the dome portion, the air flow delivers air into the vial that causes liquid to be transferred from the vial to the nozzle through the transfer conduit.
