Abstract
Personal protective equipment (PPE) and a method of wearing the PPE integrating a temperature reader biasing the temperature reader into direct thermal contact with the forehead without projecting elements and without the use of tight straps, thereby improving the comfort of the wearer while still providing face shielding functionality and accurate temperature reading. The frame has a concave curvature opposite the forehead of the wearer and the thermochromic strip is disposed as a chord across the concavity to bias the thermochromic strip against the forehead, thus reliving some of the pressure from the nosepiece to the thermochromic strip.
Claims21
A temperature-reading face shield, comprising:
- a frame comprising a nosepiece adapted to engage a nose of a human wearer;
- a pair of bows extending from opposite ends of the frame adapted to engage a surface of a head of the wearer above ears;
- a transparent sheet secured at opposite sides thereof to the respective bows to form a shield disposed outside the frame and adapted to be spaced in front of a face of the wearer;
- a temperature reader mounted at opposite ends at an inside surface to the frame, the temperature reader presenting a smooth surface adapted to engage a portion of a forehead of the wearer and sense a temperature thereof, and comprising a temperature indicator visible through the shield;
- and
- wherein the frame has a concave curvature opposite the forehead of the wearer and the temperature reader is disposed as a chord across the concavity adapted to bias the smooth surface against a portion of the forehead.
A method of integrating temperature reading into the wearing of personal protective equipment, comprising:
- engaging a nosepiece of a frame to a nose of a human wearer;
- engaging surface of a head of the wearer above ears with a pair of bows extending from opposite ends of the frame;
- securing a transparent sheet at opposite sides thereof to the pair of bows to form a shield disposed outside the frame spaced in front of a face of the wearer;
- mounting a temperature reader at opposite ends at an inside surface to the frame, the temperature reader presenting a smooth surface to engage a portion of a forehead of the wearer and sense a temperature thereof, and comprising a temperature indicator visible through the shield;
- wherein the frame has a concave curvature opposite the forehead of the wearer and the temperature reader is disposed as a chord across the concavity to bias the smooth surface against a portion of the forehead.
A temperature-reading safety glasses, comprising:
- a frame comprising a nosepiece adapted to engage a nose of a human wearer;
- a pair of bows extending from opposite ends of the frame adapted to engage a surface of a head of the wearer above ears;
- transparent safety lenses mounted in the frame;
- a temperature reader mounted at opposite ends at an inside surface to the frame, the temperature reader presenting a smooth surface adapted to engage a portion of a forehead of the wearer and sense a temperature thereof, and comprising a temperature indicator visible around the frame;
- wherein the bows are concavely curved adjacent distal ends thereof so as to be capable of engaging a rounded portion of the head to bias the frame and the nosepiece against the nose;
- and
- wherein the frame has a concave curvature opposite the forehead of the wearer and the temperature reader is disposed as a chord across the concavity adapted to bias the smooth surface against a portion of the forehead.
