Abstract
Abstract A cap for use by medical attendants provides shielding of the attendant's face for emergency use. The cap is bag-like in shape and is of a gauze-like material. It fits loosely over the user's head, but is retained by elastic around the opening. A transparent plastic shield is located in the central section of the cap. When the cap is worn conventionally, the shield faces upward and is located on top of the user's head. Pulling the forward edge of the cap downward locates the shield in front of the user's face. This shields the user from contact with any body fluids of a trauma victim while the attendant performs emergency treatment.
