ABSTRACT:
A headpiece with two built-in fan units for cooling the face and back of the neck of a surgeon while he or she is performing surgery. Each of the fan units has a fan blade mounted perpendicularly within a cylindrical housing in close tolerance with the inner wall of the housing and includes an electric motor having a drive shaft to which the fan blade is attached. The motor and fan blade assembly is supported by vanes interconnecting it with the cylindrical housing which extend radially outwardly from the axis of the assembly. The headpiece has a frame that fits a wearer's head like a hat and supports the two fan units, one in front and the other in back of the frame. The frame also supports a power source for the two fan motors and other components of circuitry which permit adjustment of the speed of each motor for optimum cooling effect. The fan units are pivotally mounted and manually adjustable to different angular positions for control of the direction of airflow in front and back of the wearer's head.
