  • Pressure-regulating ear plug
    Patent number: 5819745
    Abstract: A pressure regulating ear plug for regulating the rate of change of pressure inside an ear to minimize the pressure differential between the middle ear and a volume of the external ear cavity adjacent the ear drum is made of an ear plug adapted to fit tightly within the external ear cavity with no or minimal air leakage, and disposed within the ear plug is a pressure regulator with a slow leak rate. The pressure regulator is preferably made of a porous ceramic material.
    Type: Grant
    Filed: October 24, 1997
    Date of Patent: October 13, 1998
    Assignee: House Ear Institute
    Inventors: J. Phil Mobley, Chaoying Zhang, Sigfrid D. Soli, Chris Johnson, Drew O'Connell
