Sterile drape for use in making surgical slush
First Claim
1. A surgical drape assembly for use as a sterile container of sterile medium in a surgical slush machine having a cooled basin recessed in the top surface of the machine, said drape assembly comprising:
- a sterile conformable sheet of sufficient size to cover and hang down from the top surface of said machine to maintain a sterile field above said machine, said sheet having a container portion adapted to be substantially conformed to said basin; and
a rigid member bonded to said container portion of said sheet.

Abstract
A sterile drape assembly includes a sheet of sterile drape material bonded to a disk-like member. The drape establishes a sterile field atop a surgical slush machine and is conformable to a cooling basin 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 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.

12. A drape assembly for use with a surgical slush machine to provide a sterile drape container conformable to a cooling basin to contain a sterile slush medium formed by the cooling of the basin, said drape assembly comprising:
-
a sheet of material having top and bottom surfaces and impervious to said medium, said sheet being sized to overlie and hang down from said machine while forming a drape container substantially conformed to said cooling basin; and a disk-like member bonded to the bottom surface of said sheet below said drape container, said disk-like member being sufficiently rigid to support said sterile slush medium without bending or flexing. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. In a surgical slush machine of the type wherein a sterile medium in liquid form is contained in a liquid impervious sterile drape container conformed to a basin being cooled to cause the sterile medium to freeze and adhere to the drape adjacent cooled portions of the basin, a method for automatically detaching frozen pieces of the sterile medium from the drape, said method comprising the steps of:
-
(a) bonding a disk-like member to the bottom of said drape container; (b) automatically and repetitively raising and lowering said disk-like member to manipulate the drape relative to the basin and thereby displace said drape from cooled portions of the basin; (c) collecting said detached pieces in said drape container as sterile slush. - View Dependent Claims (20, 21)
