Abstract

A liquid-transfer adapter operatively interposable between an injector and a vial is provided. The adapter has an injector engaging portion configured for fluidly coupling to an injector and a vial coupling. The vial coupling includes a spike that has a spike axis and a tip portion configured for piercing a septum of a vial. The tip portion includes a plurality of facets that meet each other at one or more edges and at least one of the one or more edges is sloped with respect to the spike axis. The spike defines a channel extending therethrough in fluid communication with the injector engaging portion. A channel opening is defined in at least one of the facets and disposed without interrupting the edges.

Claims

1. A liquid-transfer adapter operatively interposable between an injector and a vial, comprising:

an injector engaging portion configured for fluidly coupling to an injector; and

a vial coupling including a spike that has a spike axis and a tip portion configured for piercing a septum of a vial, the tip portion including plurality of facets that meet each other at one or more edges, at least one of the one or more edges being sloped with respect to the spike axis, the spike defining a channel extending therethrough in fluid communication with the injector engaging portion and including a channel opening defined in at least one of the facets and disposed without interrupting the edges.

2. The liquid-transfer adapter of claim 1, wherein the edges comprise junctions between the facets.

3. The liquid-transfer adapter of claim 1, wherein the edges comprise cutting surfaces configured for cutting the septum as the spike is pushed therethrough.

4. The liquid-transfer adapter of claim 1, wherein the tip portion comprises at least three facets.

5. The liquid-transfer adapter of claim 4, wherein the channel opening comprises a channel opening disposed in each of at least three of the facets.

6. The liquid-transfer adapter of claim 1 further comprising a seal disposed at the injector engaging portion configured for mating with the injector for maintaining liquid within the channel and injector.

7. The liquid-transfer adapter of claim 1, further comprising a vial engaging member associated with the vial coupling configured for engaging the adapter to the vial with the spike inserted therein.

9. The liquid-transfer adapter of claim 1, wherein the channel the openings are spaced circumferentially from the edges.

10. The liquid-transfer adapter of claim 1, wherein lateral edges of the channel openings are disposed radially inward compared to the edges.

11. The liquid-transfer adapter of claim 1, wherein lateral edges of the channel openings are disposed radially inward relative to the edges at any axial position.

12. The liquid-transfer adapter of claim 1, wherein the lateral edges of the channel openings are spaced from the edges sufficiently to minimize intrusion of the septum into the channel openings when the spike is pierced through the septum.

13. The liquid-transfer adapter of claim 1, wherein the channel openings are substantially centered circumferentially on the facets.

14. The liquid-transfer adapter of claim 1, wherein the injector engaging portion comprises dimensions suitable for coupling with a needle free injector.

15. The liquid-transfer adapter of claim 14, wherein a removable insert is removably coupled within the injector engaging portion for selectively configuring the injector engaging portion for engaging variously sized injectors.

16. The liquid-transfer adapter of claim 15, wherein the removable insert comprises dimensions suitable for coupling with a syringe having a first width, and with the insert removed, the injector engaging portion is configured for coupling to a jet injector having a second width that is larger than the first width.

17. The liquid-transfer adapter of claim 1, wherein:

the spike comprises a shaft extending from the tip towards the injector engaging portion; and

opening extends onto the shaft for maximizing fluid extraction from the vial with the vial in an inverted position.

18. The liquid-transfer adapter of claim 1, wherein the edges meet at a point that is substantially axially centered.

19. The liquid-transfer adapter of claim 1, wherein the facets are substantially flat bevels.

8. The liquid-transfer adapter of claim 8, wherein the vial engaging member comprises reflexed fingers arranged around the spike and extending theretowards for snapping to and retaining the adapter engaged to the vial.

20. A liquid-transfer adapter operatively interposable between an injector and a vial, comprising:

an injector engaging portion configured for fluidly coupling to an injector; and

a vial coupling including a spike that has a spike axis and a tip portion configured for piercing a septum of a vial, the tip portion including plurality of facets that meet each other at one or more edges, at least one of the one or more edges being sloped with respect to the spike axis, the spike defining a channel extending therethrough in fluid communication with the injector engaging and including a channel opening defined in at least one of the facets, wherein the channel the openings are spaced circumferentially from the edges.

21. A liquid-transfer adapter, comprising a spike for providing liquid communication to a sealed vial, the spike including:

a shaft portion;

a piercing point configured for piercing a septum of a vial, the tip including at least three bevels joining together at a substantially centered tip;

a channel extending through the spike; and

a channel opening disposed within each bevel and onto the shaft portion and connected to the channel for transferring fluid to or from the vial.
