1. An apparatus for recovering a solution from a plurality of stoppered vials, the apparatus comprising:
- a vial holder to hold the plurality of vials stopper side down, the holder being manually movable into and out of a liquid recovery position;
a plurality of hollow needles capable of puncturing the stoppers of the vials and positioned beneath the vials, the plurality of needles and the holder being movable relative to each other between a first position in which the needles are spaced from the stoppers of the vials and a second position in which the needles puncture the stoppers of the vials;
a pump to extract a solution from the vials;
a recovery vessel to collect the solution from the vials; and
tubing connecting the needles to the pump and to the recovery vessel.

Abstract
A system allows for the safe, rapid, efficient recovery of a drug solution from sealed vials. The system is closed so that highly potent compounds can later be recovered and reworked without large investment in further engineering controls. The system includes three main components: a recovery device that holds sealed vials containing a solution, and provides means to access the contents of the vials; a peristaltic pump that pumps solution out of the vials; and a recovery tank that receives the pumped solution.

10. An apparatus for recovering a solution from a plurality of stoppered vials, the apparatus comprising:
-
a vial holder to hold the plurality of vials stopper side down, the holder being movable into and out of a liquid recovery position;
a plurality of hollow needles capable of puncturing the stoppers of the vials and positioned beneath the vials;
the plurality of needles and the holder being movable relative to each other between a first position in which the needles are spaced from the stoppers of the vials and a second position in which the needles puncture the stoppers of the vials;
a pump coupled to the needles to extract a solution from the vials; and
actuation controls for the needles to move from the lower position to the upper position, the controls requiring two simultaneous actions to cause the movement of the holder relative to the needles. - View Dependent Claims (11, 12)

13. An apparatus for recovering a solution from a plurality of stoppered vials, the apparatus comprising:
-
a vial holder to hold the plurality of vials stopper side down, the holder being movable into and out of a liquid recovery position;
a plurality of hollow needles capable of puncturing the stoppers of the vials and positioned beneath the vials, the plurality of needles and the holder being movable relative to each other between a first position in which the needles are spaced from the stoppers of the vials and a second position in which the needles puncture the stoppers of the vials; and
a pump to extract a solution from the vials;
each of the vials having a smaller diameter neck and a wider diameter body to define a shoulder, the vials each resting within the holder such that the shoulder is in contact with the holder to limit downward movement;
the needles contacting a proximal end of the vials, the apparatus further comprising a stop bar for contacting a distal end of the vials to prevent the vials from moving when the vials and needles come into contact. - View Dependent Claims (14)
