Abstract

A connector device is disclosed for establishing fluid communication between a diluent container having sidewalls and a drug vial. The connector has a piercing member having a first end and a second end and a central fluid pathway. The piercing member is mounted to the liquid container and has fluid accessing portions hermetically sealed from an outside environment. A vial receiving chamber is associated with the piercing member and is dimensioned to connect to the vial. The vial may be selectively attached to the device without piercing the closure of the vial and without breaching the hermetic seal of the fluid accessing portions of the piercing member. Means are provided for connecting the vial receiving chamber to the liquid container. The device is movable from an inactivated position, where the piercing member is outside the sidewalls and no fluid flows between the liquid container and the drug vial, to an activated position, where fluid flows through the fluid pathway between the liquid container and the drug vial. The device is movable from the inactivated position to the activated position by a force applied to the device outside the liquid container.

Claims

1. A device for connecting to a vial having a closure comprising:

a connecting base;

a plurality of segmented fingers circumferentially spaced and axially extending from the base, the segmented fingers defining a receiving chamber dimensioned to accommodate the closure of the vial, wherein the fingers have a proximal end and a distal end; and

an annular wall circumjacent the segmented fingers.

2. The device of claim 1 wherein the segmented fingers are spaced a distance therefrom to define an annular space therebetween

3. The device of claim 1 wherein at least one of the fingers has a standing rib.

4. The device of claim 1 wherein a plurality of the fingers have standing ribs.

5. The device of claim 3 wherein the standing rib tapers radially inwardly proximate the distal end of the finger.

6. The device of claim 1 wherein at least one of the fingers has a lead-in section.

7. The device of claim 6 wherein a radially-inwardly tapering tab extends from the lead-in section.

8. The device of claim 1 wherein a plurality of the fingers have radially inwardly tapering tabs extending from a lead-in section.

9. The device of claim 1 wherein a plurality of fingers have standing ribs and a plurality of fingers have radially inwardly tapering tabs extending from a lead-in section wherein the fingers with the tabs and the fingers with the ribs are disposed in alternating order about the receiving chamber.

10. The device of claim 1 wherein the distance between the annular wall and the fingers is dimensioned to allow the fingers to flex when receiving a vial.

11. The device of claim 1 wherein the annular wall is continuous and solid.

12. The device of claim 11 further comprising a seal material releasably secured to the annular wall.

13. The device of claim 12 wherein the seal material is selected from the group consisting of a foil, a polymeric material and a paper.

14. A device for connecting to a vial having a closure comprising:

a base;

an annular wall connected to the base; and

a plurality of segmented fingers circumjacent the annular wall and extending therefrom, the segmented fingers defining a receiving chamber dimensioned to accommodate the closure of the vial, wherein the fingers have a proximal end and a distal end.

15. The device of claim 14 wherein the segmented fingers are spaced a distance from the annular wall to define an annular space therebetween.

16. The device of claim 14 wherein the annular wall is solid and continuous.

17. The device of claim 14 further comprising a sealing member positioned between a bottom portion of each finger and the base.

18. The device of claim 17 wherein the sealing member is a pierceable septum.
