Abstract
A medication dispensing apparatus having an actuator that is laterally squeezable to dispense medication. The apparatus includes a supply of medication that is dispensed when a piston is advanced by a drive member. A dose to be dispensed is selectively set by operation of a dosing member, which operation causes the actuator to shift in a direction transverse to the direction the piston is advanced to dispense medication. The actuator shifts in this traverse direction from a ready position a distance that is a function of the selectively set dose. When the actuator is squeezed back to its ready position, the drive member is shifted to advance the piston to dispense the medication.
Claims12
A medication dispensing apparatus comprising:
- a housing;
- a drive member movable within said housing;
- a fluid container defining a medicine-filled reservoir with a movable piston at one end and an outlet at the other end, said piston engagable by said drive member to be advanced toward said outlet in a distal direction when said drive member is moved;
- and
- a dosing and injecting assembly for selectively shifting said drive member, said dosing and injecting assembly including an actuator and a dosing member, said dosing member operable to selectively set a dose to be delivered, said actuator movable relative to said housing in a direction transverse to said distal direction between a ready position and any one of a plurality of dosed positions, wherein said actuator, responsive to said dosing member being operated to selectively set a particular dose to be delivered, moves from said ready position to a particular dosed position that corresponds to the particular dose selectively set, and wherein said drive member, responsive to said actuator being manually shifted from said particular dosed position back to said ready position, moves to shift said piston distally to cause said set dose to be delivered through said outlet.
