Abstract

A fluid ducting assembly for enabling flow communication between a syringe and either one of a vessel and a dispenser for dispensing a fluid contained, a priori in the syringe or in the vessel. The fluid ducting assembly includes a base having a first member, a second member, and a third member for connection to and providing flow communication with the syringe, the vessel and the dispenser, respectively. The fluid ducting assembly further includes a flow controller within the base enabling any one of a flow path between the first member and the second member and a flow path between the first member and the third member. The flow controller has either a first operative position in which the flow path between the first member and the second member is enabled or a second operative position in which the flow path between the first member and the third member is enabled. The flow controller being readily switchable from its first operative position to its second operative position but not readily switchable from its second operative position to its first operative position.

Claims

1. A fluid control device for use with a vial having a container portion;

an upper, generally cylindrically shaped portion; and

an intermediate neck portion, for delivering the contents of the vial to a patient, the fluid control device including an adapter for interconnection with the vial, said adapter comprising;

(a) a top wall; and

(b) a resiliently deformable skirt connected to said wall and extending therefrom for telescopically receiving the upper portion of the vial, said skirt having;

(i) a generally cylindrical body portion;

(ii) an angularly outwardly extending marginal portion; and

(iii) an angularly inwardly extending intermediate portion disposed between said body portion and said outwardly extending intermediate portion for releasably gripping the vial.

2. The device as defined in claim 1 in which said adapter further includes a cannula connected to said top wall and extending into said skirt.

3. The device as defined in claim 1 in which said skirt is provided with a plurality of circumferentially spaced slits.

4. The device as defined in claim 1 in which said intermediate portion comprises a circumferentially extending protuberance formed intermediate said body portion and said angularly outwardly extending marginal portion.

5. The device as defined in claim 1 in which said adapter further includes a connector portion connected to said top wall and filter means for filtering the fluid within the vial, said filter means being carried by said connector portion.

6. The device as defined in claim 1 in which said adapter further includes venting means for providing an air passageway between the interior of the vial and atmosphere.

7. A fluid control device for use with a vial having a container portion;

an upper, generally cylindrically shaped portion; and

an intermediate neck portion, for delivering the contents of the vial to a patient, the fluid control device including an adapter for interconnection with the vial, said adapter comprising;

(a) a top wall; and

(b) a resiliently deformable skirt connected to said wall and extending therefrom for telescopically receiving the upper portion of the vial, said skirt having;

(i) a generally cylindrical body portion;

(ii) an angularly outwardly extending marginal portion; and

(iii) an angularly inwardly extending intermediate portion disposed between said body portion and said outwardly extending intermediate portion for releasably gripping the vial;

(c) a cannula connected to said top wall and extending into said skirt; and

(d) a connector portion connected to said top wall and extending therefrom for connecting tubing to said adapter.

8. The device as defined in claim 7 in which said adapter portion includes a tapered bore having a cavity formed therein and further includes a filter disposed within said cavity.

9. The device as defined in claim 7 in which said cannula includes first and second spaced apart lumens, said second lumen defining a venting passageway for permitting the flow of air between the interior of the vial and the exterior thereof.

10. The device as defined in claim 9 further including filter means carried by said top wall for filtering air flowing toward the exterior of the vial.

11. The device as defined in claim 9 in which said filter means comprises a filter that permits the flow of liquid therethrough, but prevents the flow of air therethrough.

12. The device as defined in claim 9 in which said skirt is provided with a plurality of circumferentially spaced slits.

14. The device as defined in claim 13 in which said skirt portion of said adapter is provided with at least two circumferentially spaced slits.

15. The device as defined in claim 16 in which said adapter is molded in a single piece from a moldable plastic.

16. The device as defined in claim 13 in which said adapter further includes a connector portion connected to said top wall and extending therefrom.

17. The device as defined in claim 16 in which said connector portion includes a tapered bore having an upper portion having an inwardly tapering wall and a lower portion having an outwardly tapering wall.

18. The device as defined in claim 17 further including filter means disposed within said lower portion of said tapered bore for filtering fluid flowing through said tapered bore.

19. The device as defined in claim 16 in which said cannula includes first and second spaced apart lumens, said second lumen defining a venting passageway for permitting the flow of air between the interior of the vial and the exterior thereof.

20. The device as defined in claim 19 further including filter means carried by said top wall for filtering air flowing toward the exerior of the vial.

13. A fluid control device for use with a vial containing a lypholized drug for mixing the lypholized drug with a diluent, the vial having a generally cylindrically shaped top portion, a body portion and an intermediate neck portion, said fluid control device comprising an adapter receivable over the top portion of the vial, said adapter comprising:

(a) a top;

(b) a resiliently deformable skirt integrally formed with said top and extending therefrom, said skirt including;

(i) a body portion

(ii) an outwardly extending marginal portion;

(iii) an inwardly extending intermediate portion located between said body portion and said marginal portion for releasably gripping the vial; and

(c) a hollow cannula connected to said top wall and extending into said skirt.
