| Abstract: |
A protective face shield intended primarily for use by health care professionals to reduce the transmission of infectious diseases carried by viral and bacterial emissions from the noses and throats of afflicted patients. The protective face shield comprises a generally flat crescent-shaped semi-rigid body member adapted to engage the forehead of the wearer. It includes a resilient head-engaging means to attach the body member to the wearer's head. The body member supports a depending semi-rigid face-covering transparent sheet which forms a barrier to the transmission of disease causing organisms. Vents are provided in the body member to prevent fogging of the shield.
