Patent ID: 7600512

Claim:
An apparatus for dispensing a fluid supplied from an external fluid source, comprising: a housing adapted for receiving the fluid from the fluid source, wherein translation of a portion of the fluid source from a stowed position to a discharge position along a first axis releases the fluid into the housing; a loading member coupled to the fluid source, the loading member imposing a biasing force on the fluid source in the stowed position to discharge the fluid source along the first axis; and a linkage coupling the housing and the fluid source, the linkage having a collapsible joint; the collapsible joint connecting first and second links configured to restrain translation of the fluid source in the first axis; the second link having a first end pivotably mounted to the housing, a second end pivotably connected to the first link at the collapsible joint, and an arm coupled to a restraining surface on a movable member; the moveable member responsive to an inhalation force, the inhalation force causing the movable member to shift the restraining surface to release the collapsible joint, thereby allowing translation of the fluid source in the first axis from the stowed position to the discharge position to discharge the fluid into the housing.
