A surgical head gear apparatus or helmet includes a lighting system that utilizes circuit board mounted LED clusters supported on the surgical helmet. The LED clusters are part of a light array mounted to the forward portion of the helmet. In one embodiment, the light array is self-contained with its own power supply. In another embodiment, the light array is electrically connected to an external power supply and controller, such as en existing controller associated with the ventilation system of the helmet. In accordance with the invention, the only remote link for the LED clusters and circuit boards is to a control switch and/or power supply.

A ventilated garment includes a head cover and a ventilation system associated with the head cover. The ventilation system can include a helmet supported by the wearer of the garment and a number of piezo fan assemblies mounted on the helmet. The piezo fan assemblies includes a number of piezo blades that generate airflow from piezo-induced oscillation of the blades. In certain embodiments, the piezo fan assemblies can include multiple outlet ducts to provide directed airflow in multiple directions.

A tourniquet cuff ( ) includes a first layer ( ), a second layer ( ), and a third layer ( ). The first layer ( ) has an inner side ( ) impermeable to air and the second layer ( ) has a first side ( ) impermeable to air. The inner side ( ) of the first layer ( ) and the first side ( ) of the second layer ( ) cooperate to define a first cavity ( ) formed to receive a gel-like material ( ) therein. Further, the third layer ( ) has an inner side ( ) which cooperates with a second side ( ) of the second layer ( ) to define a second cavity ( ) formed to receive pressurized air. The tourniquet cuff ( ) adjustably secures about a patient's limb such that the gel-like material ( ) is positioned between the patient's limb and the second cavity ( ) to uniformly and comfortably distribute pressure around the patient's limb.
