<p>A sterile drape assembly includes a sheet of sterile drape material (17) bonded to a disk-like member (19). The drape establishes a sterile field atop a surgical slush machine (10) and is conformable to a cooling basin (11) to provide a drape container impervious to the sterile slush medium. The disk-like member is preferably bonded to the bottom of the drape container and is engageable by a movable member (29) projecting into the basin. The movable member (e.g., a longitudinally reciprocable vertical shaft) moves the member and the drape to dislodge frozen pieces of the sterile medium that attach to the sides of the drape container.</p> |
