First Claim
1. In a thermal treatment system having a basin including first and second basin portions and recessed in a system top surface with a heater disposed coincident only said first basin portions to heat a sterile medium contained within said basin, an apparatus to contain said sterile medium and objects within said basin, wherein said objects disposed in said basin are thermally treated by said heated sterile medium, said apparatus comprising:
- a sterile drape for covering and hanging down from said top surface and being disposed within, and conforming to, said basin to form a drape receptacle to contain said sterile medium and objects in a sterile manner; and
object support means disposed in said sterile medium within said drape receptacle for preserving sterility of said drape receptacle by preventing air from becoming trapped between said objects and said basin and overheating and puncturing portions of said drape disposed below said objects, said object support means including a support frictionally engaged to said drape at drape locations coincident said second basin portions to support said objects above a basin floor.

Abstract
A stand is disposed in a heated thermal treatment system basin to support objects placed in the basin above the heated basin floor. The stand may be circular, rectangular or other shape to accommodate various shaped basins and prevent a surgical drape disposed in the basin and containing a heated sterile medium from puncturing. A substantially circular stand includes a substantially circular frame elevating a platform having a plurality of spokes reinforced by a plurality of concentric rings, while a substantially rectangular stand includes a substantially rectangular frame elevating a platform having a plurality of intersecting perpendicular rods to form a grid. Alternatively, the substantially circular stand may include a substantially circular platform having holes defined therein and legs extending downwardly from the platform to elevate the platform above the basin floor, while the substantially rectangular stand may include a substantially rectangular platform having holes defined therein with downwardly curved longitudinal ends to elevate the platform. The holes in the platforms, the spaces residing between the spokes and rings, and the spaces residing between the perpendicular rods, enable the stand to be submerged in the heated sterile medium and permit thermal energy from the basin to pass through the respective platforms and efficiently heat the sterile medium. The stand may be either a separate unit, or disposed integrally with the drape where the stand corresponds to the center of the basin and indicates the portions of the drape to be disposed in the basin.

1. In a thermal treatment system having a basin including first and second basin portions and recessed in a system top surface with a heater disposed coincident only said first basin portions to heat a sterile medium contained within said basin, an apparatus to contain said sterile medium and objects within said basin, wherein said objects disposed in said basin are thermally treated by said heated sterile medium, said apparatus comprising:
-
a sterile drape for covering and hanging down from said top surface and being disposed within, and conforming to, said basin to form a drape receptacle to contain said sterile medium and objects in a sterile manner; and object support means disposed in said sterile medium within said drape receptacle for preserving sterility of said drape receptacle by preventing air from becoming trapped between said objects and said basin and overheating and puncturing portions of said drape disposed below said objects, said object support means including a support frictionally engaged to said drape at drape locations coincident said second basin portions to support said objects above a basin floor. - View Dependent Claims (2, 3, 4, 5, 6, 8, 27)

7. A surgical drape for use in a thermal treatment system having a basin recessed in a system top surface with a heater disposed beneath a basin floor to heat a sterile medium contained within said basin, wherein objects disposed in said basin are thermally treated by said heated sterile medium, said drape comprising:
-
a drape portion for covering and hanging down from said top surface and being disposed within, and conforming to, said basin to form a drape receptacle to contain said sterile medium; and a support disposed on said drape portion within said drape receptacle for supporting said objects above the basin floor to protect portions of said drape coincident said heater from overheating; wherein said support is integral with said drape and disposed on said drape concentrically within the basin and indicates which portions of said drape are disposed within said basin.

9. In a thermal treatment system having a basin including first and second basin portions and recessed in a system top surface with a heater disposed coincident only said first basin portions to heat a sterile medium contained within the basin, and a sterile drape covering and hanging down from the top surface and being disposed within the basin to form a drape receptacle to contain said sterile medium in a sterile manner, wherein objects disposed in the basin are thermally treated by said heated sterile medium, a support for placement within the basin comprising:
-
a platform for receiving and supporting the objects within the basin; and elevation means for placement in said sterile medium within said drape receptacle for preserving sterility of said drape receptacle by elevating said platform above a basin floor and preventing air from becoming trapped between the objects and the basin and overheating and puncturing portions of said drape disposed below said objects, wherein said elevation means frictionally engages said drape at drape locations coincident said second basin portions. - View Dependent Claims (10, 11, 12, 13, 14, 28)
