<p>The present invention provides a multi-dose container system (10) for withdrawing multiple doses of a drug solution from the system over an extended period of time. The system has a container (12) having a port assembly (18) extending from the container (10). The port assembly (18) has a port tube (20) sealed by a stopper (22). The container (10) holds a drug solution. A bellows assembly (42) has a first end opening (48) positioned over the port assembly (18) and a second end opening (50) sealed by a septum (52). The bellows assembly (42) is movable between a first position and a second, collapsed position. A sterilization device (14) is positioned adjacent the bellows assembly (42) and is adapted to sterilize a needle (64) placed in the bellows assembly (42). A syringe assembly (16) has a syringe barrel (60) with a needle (64) at one end and a plunger (62) slidable within the syringe barrel (60). A syringe activator (44) is connected to the syringe assembly (16) for moving the syringe assembly (16) and for moving the bellows assembly (42) from the first position to the second position. A plunger activator (46) has an arm (66) connected to the plunger (62). The syringe activator (44) moves the syringe assembly (16) wherein the needle (64) pierces the septum (52) and is positioned within the bellows assembly (42). After the sterilization device (14) sterilizes the needle (64), the syringe activator (44) moves the bellows assembly (42) to the collapsed position wherein the needle (64) pierces into the port assembly (18). The plunger activator (46) then pulls back on the plunger (62) withdrawing drug solution from the container (12) into the syringe barrel (60).</p> |
