  • Athletic mouthguard with temperature indicating device
    Publication number: 20040076219
    Abstract: An athletic mouthguard including a U-shaped mouthguard body and a temperature-sensing device. The temperature-sensitive device is maintained by the mouthguard body and includes an indicator portion adapted to visually indicate information indicative of temperature. The temperature-sensing device is positioned such that upon placement of the mouthguard body within a user's mouth, the temperature-sensing device is also within the user's mouth. In this regard, the temperature-sensing device is adapted such that functioning thereof is unaffected by jarring of the mouthguard body as the user participates in an athletic activity. In one preferred embodiment, the temperature-sensing device is a thermometric strip located along an outer wall of the mouthguard body.
