Abstract

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.

Claims

1. A thermal treatment system for thermally treating a sterile medium in a sterile surgery environment, said system comprising:

a system housing including a top surface;

a basin disposed on said top surface for containing said sterile medium;

a thermal treatment unit to thermally treat said sterile medium disposed in said basin; and

a controller selectively manipulable by a user to control system operation, wherein said controller is disposed on an external sidewall of said system housing and controls operation of said thermal treatment unit to thermally treat said sterile medium in accordance with said manipulation.

2. The system of claim 1, wherein said controller is selectively manipulable through a surgical drape that covers and substantially conforms to said basin and at least a portion of said external sidewall including said controller.

3. The system of claim 1, wherein said controller includes an input device to facilitate entry of a desired temperature into said controller to control thermal treatment of said sterile medium disposed within said basin to the desired temperature.

4. The system of claim 1, further comprising a temperature indicator disposed on said system housing to selectively indicate temperature information including at least one of a measured temperature and a desired temperature for said sterile medium disposed in said basin.

5. The system of claim 4, wherein said temperature indicator includes a digital display to display said temperature information.

6. The system of claim 5, wherein said digital display is disposed on said external sidewall of said system proximate said controller and displays temperature information in a manner sufficient to be perceived through a surgical drape that covers and substantially conforms to said basin and at least a portion of said external sidewall including said digital display.

7. A thermal treatment system for thermally treating a sterile medium in a sterile surgery environment, said system comprising:

a system housing including a top surface;

a basin disposed on said top surface for containing said sterile medium;

a thermal treatment unit to thermally treat said sterile medium disposed in said basin;

a controller disposed on said system housing and selectively manipulable by a user to control system operation, wherein said controller controls operation of said thermal treatment unit to thermally treat said sterile medium in accordance with said manipulation; and

a temperature display disposed on said system housing to display temperature information including at least one of a measured temperature and a desired temperature for said sterile medium disposed in said basin.

8. The system of claim 7, wherein said temperature display digitally displays said temperature information.

9. The system of claim 7, wherein said temperature display is disposed on an external wall of said system housing and displays temperature information in a manner sufficient to be perceived through a surgical drape that covers and substantially conforms to said basin and at least a portion of said external wall including said temperature display.

10. The system of claim 7, wherein said controller includes an input device to facilitate entry of the desired temperature into said controller to control thermal treatment of said sterile medium disposed within said basin to the desired temperature.

11.
