Abstract:
A set for the isolation of cryoprecipitate includes a hollow vessel with a closed first end, a second end and a longitudinal axis, and a nipple extending from and closing the second end, said nipple enclosing a volume of approximately 2 to 5 percent of the volume of the hollow vessel. In one embodiment, the vessel is formed of a semi-rigid material and the first end is closed by a cap containing a micro-porous filter for venting the vessel. In another or further embodiment, the nipple has a tapered tip portion which may be sliced off to permit extrusion of the isolated cryoprecipitate by squeezing the vessel. In a different further embodiment, the nipple has a twist-lockable connector, for attachment to a syringe or to an applicator tip. In yet another embodiment a piston mounts on the cap within the vessel for directly extruding separated cryoprecipitate from the nipple. Preferably the set includes plural vessels, each connected to a common sterile docking connector and having a total volume of approximately 250 ml, for processing the plasma from one unit of whole blood.
