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.

8. The kit of claim 1 wherein said dispenser housing further comprises a holding chamber in fluid communication with said orifice.

9. The kit of claim 1 wherein dispenser housing further comprises a mouthpiece in fluid communication with said orifice.

10. The kit of claim 1 wherein said dispenser housing comprises a pair of laterally extending wings adapted to be gripped by a user.

11. The kit of claim 1 wherein said insert member is connected to said dispenser housing with a tether.

12. The kit of claim 1 further comprising a plug removeably received in said insert member.

13. The kit of claim 12 wherein said plug is connected to said dispenser housing with a tether.

14. The kit of claim 1 wherein said first and second container assemblies each hold a medicament.

15. The kit of claim 1 wherein said peripheral wall comprises an opening therein adjacent said support block.

16. A medication delivery device comprising:

a dispenser housing comprising a support block having a well and an orifice communicating with said well, said dispenser housing comprising a first peripheral wall defining a cavity, wherein said dispenser housing comprises an upright member extending interiorly within said cavity;

an insert member disposed in said cavity of said dispenser housing, said insert member having a second peripheral wall nesting with said first peripheral wall, and a floor defining an interior space, wherein said floor has a first opening aligned with said well of said dispenser housing and a second opening laterally spaced from said first opening, wherein said upright member extends through said second opening;

a medicament container comprising a canister and a valve stem extending through said opening in said floor and received in said well in said support block, wherein said canister is reciprocally moveable relative to said valve stem along a longitudinal axis defined by said valve stem; and

a plug removeably received in said insert member.

17. The medication delivery device of claim 16 wherein said insert member is mounted to said dispenser housing with a snap fit.

18. The medication delivery device of claim 16 wherein said insert member has a peripheral rim extending outwardly from said peripheral wall along a free edge thereof.
