A sensor for pulse oximetry or other applications utilizing spectrophotometry may be adapted to reduce motion artifacts by fixing the optical distance between an emitter and detector. A flexible sensor is provided with a stiffening member to hold the emitter and detector of the sensor in a relatively fixed position when applied to a patient. Further, an annular or partially annular sensor is adapted to hold an emitter and detector of the sensor in a relatively fixed position when applied to a patient. A clip-style sensor is provided with a spacer that controls the distance between the emitter and detector.
What is claimed is: 1. A sensor comprising: a conformable sensor body; a removable stiffening member disposed within an open cavity in the sensor body; and an emitter and a detector disposed on the stiffening member, wherein the emitter and the detector are adapted to operate in reflectance mode, a
What is claimed is: 1. A sensor comprising: a conformable sensor body; a removable stiffening member disposed within an open cavity in the sensor body; and an emitter and a detector disposed on the stiffening member, wherein the emitter and the detector are adapted to operate in reflectance mode, and wherein the sensor body is adapted to hold the emitter and detector at a substantially fixed optical distance relative to one another when the sensor is applied to a patient. 2. The sensor, as set forth in claim 1, wherein the sensor comprises at least one of a blood constituent sensor or a tissue constituent sensor. 3. The sensor, as set forth in claim 1, wherein the sensor comprises at least one of a pulse oximetry sensor or a sensor for measuring a water fraction. 4. The sensor, as set forth in claim 1, wherein the sensor comprises at least one of a carboxyhemoglobin sensor or a methemoglobin sensor. 5. The sensor, as set forth in claim 1, wherein the sensor is adapted for intrauterine use. 6. The sensor, as set forth in claim 1, wherein the stiffening member is embedded within the sensor body. 7. The sensor, as set forth in claim 1, wherein the stiffening member comprises a metal or a rigid polymeric material. 8. A pulse oximetry system comprising: a pulse oximetry monitor; and a pulse oximetry sensor adapted to be operatively coupled to the monitor, the sensor comprising: a conformable sensor body; a removable stiffening member disposed within an open cavity in the sensor body; and an emitter and a detector disposed on the stiffening member, wherein the emitter and the detector are adapted to operate in reflectance mode, and wherein the sensor body is adapted to hold the emitter and detector at a substantially fixed optical distance relative to one another when the sensor is applied to a patient. 9. The system, as set forth in claim 8, wherein the sensor comprises a tissue constituent sensor. 10. The system, as set forth in claim 8, wherein the sensor comprises a sensor for measuring a water fraction. 11. The system, as set forth in claim 8, wherein the sensor comprises at least one of a carboxyhemoglobin sensor or a methemoglobin sensor. 12. The system, as set forth in claim 8, wherein the sensor is adapted for intrauterine use. 13. The system, as set forth in claim 8, wherein the stiffening member is embedded within the sensor body. 14. The system, as set forth in claim 8, wherein the stiffening member comprises a metal or a rigid polymeric material. 15. A method of manufacturing a pulse oximetry sensor, comprising: providing a conformable sensor body adapted for use on a patient's digit; providing a removable stiffening member disposed within an open cavity in the sensor body; and providing an emitter and a detector disposed on the stiffening member, wherein the emitter and the detector are adapted to operate in reflectance mode, and wherein the sensor body is adapted to hold the emitter and detector at a substantially fixed optical distance relative to one another when the sensor is applied to a patient. 16. The method, as set forth in claim 15, wherein the sensor comprises at least one of a blood constituent sensor or a tissue constituent sensor. 17. The method, as set forth in claim 15, wherein the sensor comprises at least one of a pulse oximetry sensor or a sensor for measuring a water fraction. 18. The method, as set forth in claim 15, wherein the sensor comprises at least one of a carboxyhemoglobin sensor or a methemoglobin sensor. 19. The method, as set forth in claim 15, wherein the stiffening member is embedded within the sensor body.
