Abstract
An apparatus is provided for preparing a medical composition including a first member defining a mixing chamber having a predetermined amount of a first medical component contained therein, the first member having first and second openings each in communication with the mixing chamber, and a mixing subassembly operatively connected to the first member so that the mixing subassembly substantially seals the first opening, the mixing subassembly including a mixing member and a second member receivable one within the other. The first member and mixing subassembly are slidable guidingly, one within the other, between first and second relative positions with the first member and mixing subassembly operatively connected. The mixing member is supported for rotation relative to the first member about a first axis and includes a shaft and a plurality of paddles projecting radially from the shaft relative to the first axis and spaced, each from the other, axially relative to the first axis.
