Abstract
An instrumentality for promulgating the cryoprecipitation of fibrinogen from a blood product. The instrumentality contemplates a container for the blood product, an apparatus for creating the fibrinogen within the container and a method of manipulating the container within the apparatus and subsequently after fibrinogen has been formed. The apparatus includes a receiver within which the container is supported, a motion transfer device for the receiver to impart motion to the container while simultaneously subjecting the container to a temperature differential to cause heat transfer. The motion imparted to the container results in a thin coating of the blood product being disposed on an interior surface of the container which, in turn, is exposed to a heat transfer fluid through the wall of the container. Successive coatings placed on an interior of the container are timed such that each coating is placed on a previous coating that has changed phase. Flexure of the container after the contents of the container have been frozen can occur by providing a vacuum within the container causing an implosion of frozen material. Subsequent phase change back to a liquid and then a second freez…
