Abstract

In a modular medicament delivery system, a dispenser housing has a support block with a well and an orifice communicating with the well. A first container assembly includes a valve stem shaped to be received by the well in the support block. The first container assembly has a first exterior shape. A second container assembly includes a valve stem shaped to be received by the well in the support block. The second container assembly has a second exterior shape that is different than the first exterior shape. An insert member is adapted for mounting to the dispenser housing in the cavity and defines an interior space shaped to receive the second exterior shape of the second container. Methods of assembling the system, a system kit and a device are also provided. A medication delivery device includes first and second end pieces and a collapsible chamber disposed therebetween.

7. The medication delivery device of claim 6 wherein said first and second end pieces define an interior space therebetween when said collapsible holding chamber is in said collapsed position, wherein said collapsible chamber member is disposed in said interior space.

8. The medication delivery device of claim 7 wherein said first and second end pieces each comprise an annular wall, said annular walls of said first and second end pieces defining said interior space when said collapsible holding chamber is in said collapsed position.

9. The medication delivery device of claim 7 wherein said first and second end pieces comprise first and second grooves respectively, wherein said collapsible chamber member is received in said first and second grooves when said collapsible holding chamber is in said collapsed position.

10. The medication delivery device of claim 1 further comprising a medicament container disposed in said metered dose inhaler receptacle.

11. A medication delivery device comprising:

a collapsible holding chamber defining and moveable along a first longitudinal axis between an extended position and a collapsed position, wherein said collapsible holding chamber comprises an input port and a patient port located at opposite ends of said collapsible holding chamber, wherein said patient port defines a second longitudinal axis laterally spaced from said first longitudinal axis;

a release mechanism holding said collapsible holding chamber in said collapsed position, wherein said release mechanism comprises a tab and a receiver moveable relative to each other in a longitudinal direction between a disengaged position and an engaged position as said collapsible holding chamber is moved between said extended and collapsed positions, wherein said tab is deflectable transverse to said longitudinal direction between an insertion position and said engaged position, wherein said tab is moveable in said longitudinal direction through an opening in said receiver when said tab is in said insertion position, and wherein said tab engages an abutment surface of said receiver and prevents said tab and said receiver from being moved relative to each other in said longitudinal direction when said tab is in said engaged position, and wherein said tab comprises a grippable end portion accessible to, and engageable by, a user when said tab is in said engaged position; and

a metered dose inhaler receptacle coupled to and in fluid communication with said collapsible holding chamber, wherein said metered dose inhaler receptacle is in fluid communication with said collapsible holding chamber at a location spaced apart from and downstream of said input port, wherein separate first and second flow paths are defined respectively from and through said metered dose inhaler receptacle and said input port and into said collapsible holding chamber, and wherein at least a portion of said second flow path from said input port to said collapsible holding chamber remains unobstructed by said metered dose inhaler receptacle.

12. The medication delivery device of claim 11 further comprising a conduit communicating between said input port and said collapsible holding chamber, wherein said metered dose inhaler receptacle is coupled to said conduit and comprises a discharge orifice disposed in said conduit.

13. The medication delivery device of claim 12 wherein said orifice is aligned with said first longitudinal axis.
