Abstract
Leakage problems in a cooling system for use by medical personnel during surgery are avoided in a vest that includes a sealed, coolant receiving space through which coolant may pass. A source of liquid coolant at ambient pressure is connected to the space and a suction producing device is connected to an outlet for the space for drawing coolant from the source through the space at sub-atmospheric pressure. As a consequence, coolant will not leak from the vest in the event a leak develops. The vest may be formed of two flexible membranes sealed to each other to define the space and is provided with a coolant permeable spacer within the coolant space within the vest to prevent the membranes from collapsing upon each other.
