A medication delivery apparatus including a housing, a container of medication mounted to the housing, an outlet such as an injection needle, and a drive assembly adapted to force medication from the container and through the outlet upon movement of an actuator. The housing periphery includes a projecting abutment for digit engagement which is ergonomically designed for abutting contact by a first digit of a hand of a user when the housing is grasped within the user's hand such that a second digit of the hand of the user may operate the actuator. When the actuator is moved axially, this abutting contact of the first digit with the abutment permits application of an axial force by the first digit on the abutment in a direction generally opposite to an axial force applied to move the actuator. As this user applied force on the abutment reduces the amount of frictional force required to be applied by the user on the apparatus housing to counteract the force applied to the actuator during medication delivery, the apparatus housing may be gripped less tightly during use. The housing also is provided with a gripping layer on its periphery formed of a soft touch material.

1. A medication delivery apparatus comprising:a housing elongated in an axial direction and having a length extending between forward and rearward axial ends, said housing comprising a generally tubular base and a gripping layer covering at least a portion of said base, said gripping layer being formed from a material that is softer than a material used to form the portion of said base covered by said gripping layer; a container of medication mounted to said housing; an outlet in flow communication with said container to receive medication forced therefrom, said outlet disposed closer to the forward axial end of said housing than the rearward axial end; a drive assembly comprising an actuator movable relative to said housing from a first position to a second position, said drive assembly operatively associated with said container to deliver dosed quantities of medication from said container and through said outlet upon movement of said actuator from said first position to said second position; and said gripping layer comprising a projecting abutment for digit engagement, said abutment being axially arranged along said housing length for abutting contact by a first digit of a hand of a user when said housing is grasped within the hand of the user such that a second digit of the hand of the user may operate said actuator, said abutment comprising an ergonomically curved surface contoured to fit the user's first digit.
