ABSTRACT:
The system disclosed in U.S. Pat. No. 4,393,659 (Keyes et al) for producing surgical slush is improved to permit the slush to be collected directly in a drape or sheet, thereby eliminating the separate product basin and liquid thermal transfer medium required in the prior system. The sheet is made to conform to a heat transfer basin atop the system refrigeration unit and is impervious to the surgical liquid from which the slush is formed. In order to prevent damage to the drape by abrupt edges of basin spacers permanently projecting from the heat transfer wall into the basin interior, the spacers are covered or recessed by protective members eliminating all possible contact between the sheet and the spacer edges.
