Abstract

A conformable disposable operating room surgical hood adapted for wear with or without a face plate and exhaust system, said hood comprising
- two similar generally flat flexible non-woven, fluid resistant, inelastic side sections, the perimeter of each side section including
- a crown portion
- a back portion adjacent said crown portion
- a shoulder edge portion adjacent said back portion
- a lower face portion adjacent said perimeter shoulder edge portion, and
- an upper face portion between said lower face portion and said crown portion,
- said crown and back perimeter portions of said two side sections being joined together, generally centrally of said hood,
- an air permeable resiliently expandable inset portion joining said side section perimeter lower face portions, and
- resiliently expandable gathering means, secured to said side sections, said gathering means being secured to said side sections in stretched condition and tending to maintain said side sections across at least a portion of the rear thereof in gathered configuration,
- whereby said hood is conformable and size variable and is adapted to be worn over a face plate used with an exhaust system, said hood admitting air through said inset portion, or without such apparatus over a surgical mask alone, limiting bacterial contamination from the hood of the wearer, and tending to maintain sterile operating room conditions.
