Application device for a fluid delivery apparatus and method of use

A system comprising an application device and a fluid delivery apparatus, the application device including:

• a housing having a bore extending upward from a bottom of the housing, the bore being sized and shaped for receiving at least a portion of the fluid delivery apparatus therein,
• the application device has a retention member and an impact component positioned within the bore, the impact component being adapted for impacting the fluid delivery apparatus and moving at least a portion of the fluid delivery apparatus toward a user's skin, wherein the impact component includes a pair of upwardly extending tapered arms and a bridge portion that extends between upper ends of the tapered arms, wherein the longitudinal gap is defined between the tapered arms, the impact component being positionable relative to the housing between a safety position in which the impact component is secured to the retention member, and a released configuration in which the impact component is free to move within the housing for impacting the fluid delivery apparatus.

A method of activating a fluid delivery apparatus having a fluid therein and a plurality of microneedles for delivering the fluid to a user via the plurality of microneedles, the method comprising:

• positioning the fluid delivery apparatus relative a portions of the user's body such that the plurality of microneedles are adjacent the user's skin;
• positioning an application device into direct contact with the fluid delivery apparatus;
• activating the application device to cause a piston of the application device to contact the fluid delivery apparatus at a predetermined velocity and drive the plurality of microneedles into the user's skin at a velocity in the range between 4.5 meters/second (m/s) to 6 m/s, wherein the piston includes a pair of upwardly extending tapered arms and a bridge portion that extends between the upper ends of the tapered arms, wherein the longitudinal gap is defined by the tapered arms.
