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.

Claims

1. A kit for assembling 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 peripheral wall defining a cavity;

a first container assembly comprising a valve stem shaped to be received by said well in said support block, said first container assembly having a first exterior shape and being reciprocally moveable along a longitudinal axis defined by said valve stem, wherein said first exterior shape is shaped to be received in said cavity;

a second container assembly comprising a valve stem shaped to be received by said well in said support block, said second container assembly having a second exterior shape and being reciprocally moveable along a longitudinal axis defined by said valve stem, wherein said second exterior shape is different than said first exterior shape; and

an insert member adapted for mounting to said dispenser housing in said cavity and defining an interior space shaped to receive said second exterior shape of said second container;

wherein both of said first container assembly and said second container assembly in combination with said insert member are adapted to be mounted in said dispenser housing, and wherein said first container assembly in combination with said insert member is not adapted to be mounted in said dispenser housing.

2. The kit of claim 1 wherein said insert member has a third exterior shape shaped to be received in said cavity.

3. The kit of claim 1 wherein said insert member comprises a floor having an opening therethrough, wherein said opening is aligned with said well when said insert member is mounted in said dispenser housing.

4. The kit of claim 1 wherein said first container assembly comprises a container filled with a medicament and a dose counter secured to said container.

5. The kit of claim 4 wherein said dispenser housing comprises an actuator member adapted to interface with said dose counter.

6. The kit of claim 5 wherein said actuator member comprises an upright finger.

7. The kit of claim 5 wherein said insert member has an opening shaped to receive said actuator member.

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. 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;

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 an opening aligned with said well of said dispenser housing; and

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.

15. The medication delivery device of claim 14 wherein said insert member is mounted to said dispenser housing with a snap fit.

16. The medication delivery device of claim 14 wherein said insert member has a peripheral rim extending outwardly from said peripheral wall along a free edge thereof.

17. The medication delivery device of claim 14 wherein said dispenser housing comprises an upright member extending interiorly within said cavity, and wherein said opening of said insert member comprises a first opening, and wherein said insert member has a second opening receiving said upright member.

18. The medication delivery device of claim 14 wherein said dispenser housing further comprises a holding chamber in fluid communication with said orifice.

19. The medication delivery device of claim 14 wherein dispenser housing further comprises a mouthpiece in fluid communication with said orifice.

20. The medication delivery device of claim 14 wherein said dispenser housing comprises a pair of laterally extending wings adapted to be gripped by a user.

21. The medication delivery device of claim 14 wherein said insert member is connected to said dispenser housing with a tether.

22. The medication delivery device of claim 14 further comprising a plug removeably received in said insert member.

23. The medication delivery device of claim 15 wherein said plug is connected to said dispenser housing with a tether.

24-31. -31. (canceled)

32. A ventilator system comprising:

a dispenser housing in fluid communication with an oxygen intake line and a patient interface, said dispenser housing comprising a support block having a well and an orifice communicating with said well, said dispenser housing comprising a peripheral wall defining a cavity; and

an insert member adapted for releasable mounting to said dispenser housing in said cavity and defining an interior space, said insert member having a floor with an opening adapted to be aligned with said well of said dispenser housing when said insert member is mounted to said dispenser housing.

33. The ventilator system of claim 32 further comprising a first container assembly comprising a valve stem shaped to be received by said well in said support block, said first container assembly shaped to be disposed in said interior space of said insert member.

34. The ventilator system of claim 32 wherein said dispenser housing comprises a pair of laterally extending wings adapted to be gripped by a user.

35. The ventilator system of claim 32 wherein said insert member is connected to said dispenser housing with a tether.

36. The ventilator system of claim 32 further comprising a plug removeably received in said insert member.

37. The ventilator system of claim 36 wherein said plug is connected to said dispenser housing with a tether.
