  • Patent number: 5732410
    Abstract: A face shield apparatus to prevent bodily fluids and foreign materials from splashing into the user's face in medical situations. In non-medical use, this invention relates generally to preventing non-impact exposure from liquid splash, dirt and dust. The apparatus includes a transparent face portion providing a flat viewing area in front of the user's eyes, a forehead barrier portion to protect the user against splash to the eyes from above, a head strap portion to fit around the user's head to hold the face shield in place, and a drape portion to protect against splash coming up under the shield. This drape portion features a fluid-impermeable fabric below the plastic to cover the user's chin and upper neck. Light pressure to the bottom of the fluid barrier fabric closes the fabric under the user's chin with fasteners.
