Patent ID: 8414555

Claim:
A medicament transport system for a medicament contained in a vial, the medicament transport system comprising: a syringe adapter assembly fluidly connectable to a first container, the syringe adapter assembly including: a body portion defining a lumen therethrough; and a seal member connected to a distal end of the body portion and extending across the lumen thereof; and a vial adapter assembly connectable to a neck of the vial and configured to receive the body portion of the syringe adapter assembly, the vial adapter assembly including: a base having at least one retainer configured to engage the neck of the vial, the base defining an opening having a seal member disposed therewithin; a stem extending from the base, the stem defining a lumen therethrough and being in operative communication with the opening of the base, the stem defining an opening through a wall thereof; a needle shuttle valve slidably disposed within the lumen of the stem, the needle shuttle valve forming a fluid tight seal with the stem, the needle shuttle valve supporting a transfer needle such that the transfer needle extends from a first and a second end thereof and supporting a vacuum needle such that the vacuum needle extends from the first end of the needle shuttle valve; and a vacuum cup slidably supported on the stem, the vacuum cup being in fluid tight contact with the stem and with the base, wherein a vacuum chamber is defined in the space between the base, the stem and the vacuum cup, the vacuum chamber being in fluid communication with the lumen of the stem through the opening formed in the wall of the stem; wherein the medicament transport system includes a first condition in which the needle shuttle valve is in a retracted position such that the transfer needle and the vacuum needle do not extend through the seal member of the base of the vial adapter, and the vacuum cup is in an advanced position such that the volume of the vacuum chamber is at a minimum; wherein the medicament transport system includes a second condition in which the body portion of the syringe adapter assembly is advanced through the lumen of the stem such that the second end of the transfer needle penetrates through the seal member of the body portion and the needle shuttle valve is advanced through the lumen of the stem to penetrate the first end of the transfer needle and a tip of the vacuum needle through the seal member of the vial adapter assembly, and wherein the vacuum needle is brought into fluid communication with the opening formed in the wall of the stem; and wherein the medicament transport system includes a third condition in which the vacuum cup is moved to a proximal position thereby enlarging the vacuum chamber and drawing a vacuum through the vacuum needle.
