  • Shunt barrier in pulse oximeter sensor
    Patent number: 6763255
    Abstract: A pulse oximeter sensor having an emitter(s) and a detector, with a layer having a first portion of the emitter and a second portion of layer over the detector is provided. A barrier is included between the first and second portions of the overlying layer to substantially block radiation of the wavelengths emitted by the emitter(s). Preferably, the barrier reduces the radiation shunted to less than 10% of the radiation detected, and more preferably to less than 1% of the radiation detected.
    Type: Grant
    Filed: July 12, 2002
    Date of Patent: July 13, 2004
    Assignee: Nellcor Puritan Bennett Incorporated
    Inventors: Russ DeLonzor, Paul D. Mannheimer, Michael E. Fein, Don Hannula
