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 substantially annular or partially annular rigid sensor body configured to retain the sensor on a patient's digit, wherein the sensor body forms a tissue-contacting surface of the sensor; andan emitter and a detector disposed on the tissue-contacting surf
What is claimed is: 1. A sensor comprising:a substantially annular or partially annular rigid sensor body configured to retain the sensor on a patient's digit, wherein the sensor body forms a tissue-contacting surface of the sensor; andan emitter and a detector disposed on the tissue-contacting surface of the sensor body, wherein the sensor body is adapted to hold the emitter and detector at a fixed optical distance relative to one another and relative to the patient's digit when the sensor is attached to a patient and when the sensor experiences an external tapping force or when the digit applies a flexing force to the sensor.
