Multiple wavelength sensor attachment
First Claim
1. A physiological sensor adapted to removably attach an emitter assembly and a detector assembly to a fingertip, the emitter assembly adapted to transmit optical radiation having a plurality of wavelengths into fingertip tissue, the detector assembly adapted to receive the optical radiation after attenuation by the fingertip tissue, the sensor comprising:
- a first shell;
a second shell hinged to the first shell;
a spring disposed between and urging together the shells, the spring including a first leg pressing against the first shell and a second leg extending along the second shell,wherein the first shell and second shell and spring are adapted to create a pivot point along a finger gripped between the shells that is substantially behind the fingertip;
an emitter pad fixedly attached to the first shell and configured to retain the emitter assembly;
a detector pad fixedly attached to the second shell configured to retain the detector assembly;
a detector aperture defined within the detector pad and adapted to pass optical radiation to the detector assembly; and
a contour defined along the detector pad and generally shaped to conform to the fingertip when said finger is positioned over the detector aperture.

Abstract
A physiological sensor is adapted to removably attach an emitter assembly and a detector assembly to a fingertip. The emitter assembly is adapted to transmit optical radiation having multiple wavelengths into fingertip tissue. The detector assembly is adapted to receive the optical radiation after attenuation by the fingertip tissue. The sensor has a first shell and a second shell hinged to the first shell. A spring is disposed between the shells and urges the shells together. An emitter pad is fixedly attached to the first shell and configured to retain the emitter assembly. A detector pad is fixedly attached to the second shell and configured to retain the detector assembly. A detector aperture is defined within the detector pad and adapted to pass optical radiation to the detector assembly. A contour is defined along the detector pad and generally shaped to conform to a fingertip positioned over the detector aperture.

13. A physiological sensor method comprising:
-
providing a plurality of housing elements comprising pads and shells; mounting a sensor assembly within the housing elements; providing a spring within the housing elements, the spring including a first leg pressing against a first shell and a second leg extending along a second shell, wherein the first shell and second shell and spring are adapted to create a pivot point along a finger gripped between the shells that is substantially behind the fingertip; positioning a fingertip relative to the sensor assembly with a plurality of pad features, wherein the first pivot point is proximal to the fingertip and the second pivot point is distal to the fingertip; and urging the housing elements against the fingertip so as to removably attach the sensor assembly to the fingertip. - View Dependent Claims (14, 15, 16, 17, 18)
