Patent ID: 6934570

Claim:
A physiological sensor combination comprising: a flexible substrate configured to attach to a tissue site; a plurality of sensors disposed on said substrate and adapted to provide a corresponding plurality of physiological signals, each of said signals responsive to at least one of a plurality of physiological parameters; a plurality of conductors disposed on said substrate between said sensors and at least one connector, and said at least one connector configured to communicate said signals to at least one monitor so as to derive a plurality of measurements of said parameters, wherein said sensors comprise: a plurality of electrodes disposed on said substrate, each of said electrodes adapted to be in electrical communication with said tissue site and electrically connected to at least one of said conductors; and an emitter and a detector mounted to said substrate and electrically connected to at least one of said conductors, said emitter adapted to transmit light into said tissue site and said detector adapted to receive reflected light from said tissue site, wherein: said substrate has a first side adapted to face toward said tissue site and a second side adapted to face away from said tissue site; said conductors and said electrodes disposed on said first side; and said emitter and said detector mounted to said first side wherein said substrate comprises a fold-over portion having a circuit side corresponding to said first side, and said fold-over portion adapted to fold so that said circuit side is proximate said second side.
