Abstract:
An actuator for use in dispensing a medicament from a container having at least a first and second portion, said actuator comprising:a holder having a grippable portion, wherein said holder is adapted to engage at least the first portion of the container; a trigger member pivotally connected to said holder at a pivot axis, wherein said trigger member is pivotable about said pivot axis in a first rotational direction toward said grippable portion and a second rotational direction opposite said first direction, wherein said trigger member follows a path as said trigger member is pivoted about said pivot axis in said first rotational direction; a push member connected to said trigger member, wherein said push member is pivotable about said pivot axis in said first rotational direction in response to said trigger member pivoting in said first rotational direction, wherein said push member is pivotable about said pivot axis in said second rotational direction as said trigger member is pivoted in said second rotational direction, wherein said push member comprises an engagement portion adapted to engage the second portion of the container, wherein said push member is adapted to move at least the second portion of the container relative to said holder, and wherein at least a portion of said push member is moved in a substantially non-parallel relationship to at least a portion of said trigger member as said push member and said trigger member are pivoted in the first and second rotational directions respectively; and a stop member moveable between an engaged position and a disengaged position, wherein said stop member is engaged with said push member and immobilizes said engagement portion when said stop member is in said engaged position, and wherein said stop member is maintained in said engaged position as said trigger member is pivoted in said first rotational direction along at least a portion of said path.
