Abstract
A pulse oximetry sensor has an emitter adapted to transmit optical radiation of at least two wavelengths into a tissue site and a detector adapted to receive optical radiation from the emitter after tissue site absorption. A tape assembly is adapted to attach the emitter and detector to the tissue site. A flexible housing is disposed around and optically shields the detector.

15. A pulse oximetry sensor method comprising the steps of:
-
providing an emitter adapted to transmit optical radiation of at least two wavelengths into a tissue site; providing a detector adapted to receive optical radiation from said emitter after absorption by pulsatile blood flowing within said tissue site; incorporating said emitter and said detector within a cable assembly adapted to provide electrical communications between said emitter and said detector and a monitor; EMI shielding said detector so as to reduce electromagnetic noise; optically shielding said EMI shielded detector with an opaque, flexible housing so as to reduce optical noise from ambient light and piped light by forming a pocket within said flexible housing and enclosing said EMI shielded detector into said pocket; and disposing said cable assembly within a tape assembly adapted to attach said emitter and said detector to a tissue site. - View Dependent Claims (16, 17, 18, 19)
