A thermal treatment system for thermally treating a sterile medium is controlled via a foot actuated switch to thermally treat the sterile medium to a desired temperature and/or form (e.g., slush). The thermal treatment system includes a basin recessed in a system top surface, while a surgical sterile drape is placed over the system and within the basin to form a drape container for containing the sterile medium. The basin may be configured to cool the sterile medium and form sterile surgical slush, or heat the sterile medium to provide warm sterile liquid. A dislodgment mechanism may be employed within a cooling basin to manipulate the drape and dislodge frozen pieces of sterile medium adhered to the drape. Information pertaining to the sterile medium and system operation may be displayed on a system display that has dimensions sufficient to provide visibility of the information to users located within extended ranges from the system. Alternatively, the thermal treatment system may be responsive to a remote control unit to enable users to control operation of the system remotely. The remote control unit may control various operating parameters and features of the system, and preferably emits system commands in the form of code signals. A receiver is employed by the thermal treatment system to receive the transmitted signals and facilitate system operation in response to those signals. In addition, the foot actuated switch and remote control unit may be utilized with thermal treatment systems having a plurality of heating and/or cooling basins.
