PALM ACTIVATED DRUG DELIVERY DEVICE

A medication administering device includes upper and lower housings. The lower housing supports a syringe having a needle. A needle guard is in sliding engagement with the lower housing and is proximally movable from a first position, wherein the needle guard conceals a tip of the needle, to a second position, wherein the needle guard exposes the tip of the needle. The upper housing is configured to receive a distally directed force and move relative to the lower housing from a pre-use position to a dispensed position in response to the manual force. When the upper housing is in the pre-use position and the needle guard is in the first position, the upper housing cannot move toward the dispensed position. Proximal movement of the needle guard from the first position to the second position frees the upper housing for movement to the dispensed position in response to the force.
