ABSTRACT:
An infusion device comprising a housing having a base plate disposed therein which is slidably moveable between first and second positions. Attached to the base plate and the housing is a biasing mechanism for biasing the base plate to the second position. Also disposed within the housing is an actuator plate which is slidably moveable between inner and outer positions. The actuator plate is cooperatively engaged to the base plate in a manner wherein the movement of the base plate toward the second position facilitates the movement of the actuator plate toward the outer position, with the movement of the base plate toward the first position facilitating the movement of the actuator plate toward the inner position. Slidably attached to the housing in spaced relation to the actuator plate is a lid member. The lid member, the actuator plate and the housing define a medicament chamber when the lid member is in a closed position. The movement of the actuator plate toward the outer position reduces the volume of the medicament chamber, with the movement of the actuator plate toward the inner position increasing the volume of the medicament chamber.
