Abstract:
1. Apparatus for reconstituting a medicament in a vial with a liquid from a syringe, the apparatus comprising: a body portion defining an interior cavity and having first, second, and third fluid ports communicating with the interior cavity, the body portion further defining a body lumen extending through the body portion without intersecting the interior cavity, and fourth and fifth fluid ports communicating with each other bidirectionally through the body lumen; a fitting on the first fluid port configured to receive a syringe; a fluid regulating element located within the interior cavity and configured to be selectively movable among (a) a first position in which fluid communication through the interior cavity is blocked, (b) a second position in which fluid communication is open through the interior cavity between the first and second fluid ports, and (c) a third position in which fluid communication is open through the interior cavity between the first and third fluid ports; an adapter assembly fixed to the body portion and configured for removable attachment of a medicament vial so that the vial is in fluid communication with the second fluid port and the fourth fluid port; and an expansible air chamber operatively connected to the fifth fluid port so as to allow the bidirectional passage of air through the body lumen between the air chamber and the fourth fluid port.
