Liquid-transfer adapter beveled spike
First Claim
1. A liquid-transfer adapter operatively interposable between an injector and a vial, comprising:
- an injector engaging portion configured for fluidly coupling to the injector;
a vial coupling including a spike that has a spike axis and a tip portion configured for piercing a septum of the 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;
a body adjacent the injector engaging portion, the spike extending from the body;
a collar coupled to the body by a support structure such that the collar is spaced from the body by a distance that is greater than a length of the spike, the collar comprising a continuous circumferential collar; and
fingers having a proximal end and a distal end, the distal end coupled to the collar and extending inwardly and proximally toward the injector engaging portion, the fingers configured to couple the liquid-transfer adapter to the vial, wherein the proximal end comprises a free end.

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.
