Liquid-transfer adapter beveled spike

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;

a vial coupling including a spike having a spike axis and a tip portion configured for piercing a septum of a vial, and a plurality of facets each forming a flat bevel that meet each other at the tip portion, wherein each of the plurality of facets are sloped with respect to the spike axis, wherein two or more of the plurality of facets meet one another 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 plurality of facets, the channel opening being disposed without interrupting the one or more edges; and

a collar associated with the vial coupling and configured to act as a guide for engaging the liquid-transfer adapter to the vial with the spike inserted therein.

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

3. The liquid-transfer adapter of claim 1 , wherein the one or more 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 the 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 or a removable insert for maintaining liquid within the channel and injector.

7. The liquid-transfer adapter of claim 1 , wherein the channel opening is spaced circumferentially from the one or more edges.

8. The liquid-transfer adapter of claim 1 , wherein lateral edges of the channel opening are disposed radially inward compared to the one or more edges.

9. The liquid-transfer adapter of claim 1 , wherein lateral edges of the channel opening are disposed radially inward relative to the one or more edges at any axial position.

10. The liquid-transfer adapter of claim 1 , wherein lateral edges of the channel opening are spaced from the one or more edges and configured to reduce or minimize intrusion of the septum into the channel opening when the spike is pierced through the septum.

11. The liquid-transfer adapter of claim 1 , wherein the channel opening is centered circumferentially on at least one of the plurality of facets.

12. The liquid-transfer adapter of claim 1 , wherein the injector engaging portion is configured for coupling with a needle free injector or a removable insert.

13. The liquid-transfer adapter of claim 12 , wherein a removable insert is removably coupled to the injector engaging portion for selectively engaging different injectors.

14. The liquid-transfer adapter of claim 13 , wherein the removable insert is configured for coupling with a syringe having a first width, and with the removable 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.

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

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

the channel opening extends from at least one of the plurality of facets onto the shaft of the spike, the channel opening configured for extracting fluid from the vial with the vial in an inverted position.

16. The liquid-transfer adapter of claim 1 , wherein the one or more edges meet at a point on the spike axis.

17. The liquid-transfer adapter of claim 1 , wherein the collar includes a height configured to predispose insertion of the spike in a vial septum target.

18. The liquid-transfer adapter of claim 1 , wherein the collar includes a height configured to predispose insertion of the spike in the vial septum to avoid a stopper sidewall.

19. The liquid-transfer adapter of claim 1 , wherein the collar is configured to attach to a vial with the liquid-transfer adapter at angles relative to the vial without impeding fluid introduction into the vial or withdrawal of fluid from the vial.

20. The liquid-transfer adapter of claim 1 , wherein the collar comprises reflexed fingers arranged around the spike and extending theretowards for snapping to and retaining the liquid-transfer engaged to the vial.

21. The liquid transfer adapter of claim 2 , wherein the junctions comprise a cutting surface configured to cut the septum when the spike is inserted in the vial.
