Abstract

A fluid adapter for connection between a valve having a plurality of ports and a tube has a housing with a distal end and a proximal end. The tube has a single lumen. The proximal end has a first opening connecting to a first lumen being disposed through the housing. The proximal end has a second opening being separated by the first opening by a distance. The second opening is connecting to a second lumen being disposed through the housing. The distal end has the first lumen connecting to a single outlet and the second lumen terminates in the housing. The adapter also has the single outlet of the housing connected to the intermediate tube. The intermediate tube is connected to the tube to permit fluid to traverse through the tube and the valve. Additionally, a valve system has a valve connector including a portion of a first passageway with the valve connector further including a suction port and an introduction port that are spaced apart. The suction port and the introduction port establish fluid communication between the portion of the first passageway and the suction port or the introduction port. At least one port of the valve connector has a collar. The collar is adapted to press fit with a medical device.

Claims

1. A fluid adapter for connection between a valve having a plurality of ports and a tube, the tube having a single lumen, the fluid adapter comprising:

a housing having a distal end and a proximal end;

wherein said proximal end has a first opening connecting to a first lumen being disposed through said housing;

wherein said proximal end has a second opening being separated by said first opening by a distance, said second opening connecting to a second lumen;

wherein said distal end has said first lumen connecting to a single outlet;

wherein said second lumen terminates in said housing;

wherein said single outlet of said housing connects to an intermediate tube; and

wherein said intermediate tube is connected to the tube to permit fluid to traverse through the tube and the valve.

2. The fluid adapter of claim 1, wherein said intermediate tube is connected to a member having a distal end with a neck portion configured to permit the tube having the single lumen to fasten over said neck portion.

3. The fluid adapter of claim 2, wherein said neck portion of said member comprises a plurality of flanges.

4. The fluid adapter of claim 3, wherein said plurality of flanges are configured to form a barb-like configuration to retain the tube thereon in a sealed manner.

5. The fluid adapter of claim 4, wherein said plurality of flanges has at least one with a first diameter and at least another flange with a second diameter with said first diameter and said second diameter being differently sized diameters.

6. The fluid adapter of claim 4, wherein said plurality of flanges are sized to facilitate retention of the tube in a sealed manner.

7. The fluid adapter of claim 4, wherein said plurality of flanges has at least one with a first diameter and at least another flange with a second diameter with said first diameter and said second diameter being differently sized diameters to facilitate retention of the tube.

8. The fluid adapter of claim 1, wherein said housing is generally cylindrical and sized to be manipulated by hand.

9. The fluid adapter of claim 8, wherein said intermediate tube has a length, wherein said length is suitable to rotate the valve being connected to the housing without disengaging said housing from the valve.

10. The fluid adapter of claim 1, wherein said first lumen is generally cylindrical.

11. The fluid adapter of claim 1, wherein said second lumen is generally cylindrical and terminates at an end.

12. The fluid adapter of claim 1, wherein said housing is made from a flexible material.

13. The fluid adapter of claim 1, wherein at least one of said first lumen and said second lumen has a first size being relatively smaller than another of said first lumen and said second lumen to accommodate the plurality of ports of the valve.

14. The fluid adapter of claim 13, wherein at least one lumen terminates at an end to close at least one of the plurality of ports of the valve, said closed port being a vent port.

15. The fluid adapter of claim 2, wherein said intermediate tube is connected to a flanged member having a plurality of flanges to permit the tube having the single lumen to fasten over the plurality of flanges.

16. The fluid adapter of claim 1, wherein said intermediate tube is transparent and configured to permit a visual inspection thereof.

17. A fluid adapter for connection between a valve and a tube having a single lumen, the fluid adapter comprising:

a housing having a distal end and a proximal end;

wherein said proximal end has a first opening connecting to a first lumen being disposed through said housing;

wherein said proximal end has a second opening being separated by said first port by a distance, said second opening being a close ended port connecting to a second lumen;

wherein said distal end has said first lumen connected to a single outlet, said outlet connecting to the tube having the single lumen; and

wherein said housing is configured to be releasably connected to the valve.

18. The fluid adapter of claim 17, wherein said housing further comprises a tab being configured to releasably connect over a secondary port of the valve, said tab being configured to prevent the user from toggling said secondary port.

19. The fluid adapter of claim 17, wherein said housing further comprises a tab being configured to occlude a secondary port of the valve, said tab being configured to prevent the user from toggling said secondary port.

20. The fluid adapter of claim 17, wherein said housing is made from a thermoplastic.

21. The fluid adapter of claim 17, wherein said housing is made from a material selected from the group consisting of a phthalate free polyvinyl chloride, a HDPE plastic, a PP plastic, and any combination thereof.

22. The fluid adapter of claim 17, wherein at least one opening has a compression fit, and wherein another opening has a relatively looser fit relative to said compression fit.

23. The fluid adapter of claim 17, wherein said single outlet has a neck portion with a plurality of flanges, said plurality of flanges forming a barb like configuration to connect with the tube in a sealed manner.

24. A valve system comprising:

a valve connector including a portion of a first passageway, the valve connector further including a suction port and an introduction port that are spaced apart, the suction port and the introduction port establishing fluid communication between the portion of the first passageway and the suction port or the introduction port;

wherein at least one port of the valve connector has a collar, said collar being adapted to press fit with a medical device.

25. The valve system of claim 24, wherein said collar is generally cylindrical and has an inner periphery and an exterior surface, wherein said inner periphery has at least one protrusion.

26. The valve system of claim 24, wherein said collar is a made from a flexible material.

27. The valve system of claim 24, wherein said at least one port has a reduced diameter at an end;

and

wherein said collar is connected at said end to provide for a substantially uniform diameter with said collar and said at least one port along said length of said at least one port.

28. The valve system of claim 24, wherein collar is ultrasonically bonded to said at least one port.

29. The valve system of claim 24, wherein collar is RF bonded to said at least one port.
