Patent ID: 8821436

Claim:
A fluid transfer device comprising: a housing comprising an elongated passage having at least one open end, the elongated passage having a longitudinal axis; a first piercing assembly associated with the housing projecting normal to the longitudinal axis of the elongated passage, the first piercing assembly adapted for accessing a first container, the first piercing assembly comprising a first piercing member having at least one conduit in fluidic communication with the elongated passage; a second piercing assembly associated with the housing projecting normal to the longitudinal axis of the elongated passage, the second piercing assembly adapted for accessing a second container, the second piercing assembly comprising a second piercing member having at least one conduit in fluidic communication with the elongated passage; a connector coupled to the housing, the connector adapted to receive a fluid delivery device and in fluidic communication with the elongated passage; and a user-actuated plunger at least partially slidably disposed in the elongated passage of the housing, linearly translatable along the longitudinal axis thereof independent of a fluid delivery device connected to the connector, the user-actuated plunger comprising: a first flow channel and a second flow channel, the second flow channel being distally separated from the first flow channel, wherein the user-actuated plunger is configured to slidably move without rotation during use within the passage between (i) a first predetermined position wherein the first flow channel provides fluid communication directly between the connector and the at least one conduit of the first piercing member, and (ii) a second predetermined position, wherein the second flow channel provides fluid communication directly between the connector and the at least one conduit of the second piercing member.
