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.
Claims22
A pulse oximetry sensor comprising:
- an emitter adapted to transmit optical radiation of at least two wavelengths into a tissue site;
- a detector adapted to receive optical radiation from said emitter after tissue site absorption;
- a tape assembly adapted to attach said emitter and said detector to said tissue site;
- and
- a flexible housing defining a pocket, said pocket configured to position and optically shield said detector.

A pulse oximetry sensor comprising:
- a detector adapted to receive optical radiation from an emitter after absorption by pulsatile blood flowing within a tissue site;
- a shielded detector assembly having an EMI shield at least partially covering said detector;
- a housing assembly having a flexible housing at least partially covering said shielded detector assembly,wherein said housing defines a pocket configured to position and optically shield said detector;
- and
- a tape assembly folded around said housing assembly and adapted to attach said detector and said emitter to said tissue site.

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.
