Abstract

A dual-lumen needle for aseptic filling and withdrawal of fluids from septum-plugged containers

Claims

1. A dual-lumen needle comprising:

a first elongate lumen comprising opposed first and second ends and an elongate first tubular body extending therebetween, said first tubular body defining an elongate passageway in fluid communication with said first and second open ends of said first lumen, wherein said second open end of said first lumen defines a flow port; and

a second elongate lumen comprising opposed first and second ends and an elongate second tubular body extending therebetween, said second tubular body defining an elongate passageway in fluid communication with said first and second open ends of said second lumen, wherein at least a portion of said second lumen extends along said first lumen and said second open end of said second lumen defines a vent port.

2. A dual-lumen needle of claim 1, further comprising filtration media defining a gas passageway therethrough, said gas passageway in fluid communication with said second passageway of said second lumen.

3. A dual-lumen needle of claim 1, wherein said filtration media extends across said second passageway of said second lumen.

4. A dual-lumen needle of claim 1, wherein said filtration media extends across said second passageway of said second lumen adjacent to one of said first and second ends of said second lumen.

5. A dual-lumen needle of claim 1, wherein said filtration media is removable from said second lumen.

6. A dual-lumen needle of claim 1, wherein said vent port is located adjacent to said flow port of said first lumen.

7. A dual-lumen needle of claim 1, wherein said vent port is longitudinally-spaced from said flow port.

8. A dual-lumen needle of claim 1, wherein said flow port and said vent port are each defined by a corresponding beveled tip, said beveled tips being aligned to provide a single puncture of a septum into which the needle is inserted.

9. A dual-lumen needle of claim 1, wherein said first lumen has a cross-sectional dimension of a 16 gauge needle.

10. A dual-lumen needle of claim 1, wherein said first lumen has a cross-sectional dimension less than a 16 gauge needle.

11. A dual-lumen needle of claim 1, wherein said flow port opens in a direction substantially transverse to the longitudinal axis of said first tubular body.

12. A dual-lumen needle of claim 1, wherein said flow port is axially-aligned with the longitudinal axis of said first tubular body.

13. A dual-lumen needle of claim 1, wherein said first end of said first lumen supports a hub having a luer fitting thereon.

14. A dual-lumen needle of claim 1, wherein said first end of said second lumen supports a hub having a luer fitting thereon.
