a housing elongated in an axial direction, said
housing comprising a housing exterior periphery and a
length extending between forward and rearward axial ends;
a container of medication mounted to said housing;
an outlet in flow communication with said container
to receive medication forced therefrom;
a drive assembly comprising an actuator, said
actuator advanceable toward said housing in said axial
direction from a first position beyond said rearward
axial end of said housing to a second position to deliver
a dosed quantity of medication, said drive assembly
operatively connected with said container to force said
dosed quantity of medication therefrom and through said
outlet upon movement of said actuator from said first
position to said second position; said housing
exterior periphery comprising a projecting abutment for
digit engagement, said abutment comprising an
ergonomically curved surface 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, whereby abutting
contact of the first digit with said abutment permits
application of a generally axial force by the first digit
on said abutment in a direction generally opposite to an
axial force applied to said actuator during advancement
of said actuator from said first position to said second
position; and
a dosage member operable to control said dosed
quantity of medication delivered by said drive assembly.
