Abstract: Devices, systems, and methods for combining and/or delivering an injectable material to a patient. A vial adaptor is configured to fluidly couple at least a first chamber and a separate chamber and to facilitate fluid exchange therebetween as well as to vent the separate chamber as material is withdrawn therefrom. The first chamber may be defined in a multi-chamber device which further defines a second chamber. The vial adaptor further defines a purge reservoir into which excess material and/or air may be purged from the second chamber. For instance, as material is ejected from the first chamber into the separate chamber, a determined amount of material may be purged from the second chamber into the purge reservoir.
