Abstract
Systems and methods are disclosed for proximity sensing in physiological sensors, and more specifically to using one or more proximity sensors located on or within a physiological sensor to determine the positioning of the physiological sensor on a patient measurement site. Accurate placement of a physiological sensor on the patient measurement site is a key factor in obtaining reliable measurement of physiological parameters of the patient. Proper alignment between a measurement site and a sensor optical assembly provides more accurate physiological measurement data. This alignment can be determined based on data from a proximity sensor or sensors placed on or within the physiological sensor.

22. A method for preparing a physiological sensor for use in monitoring a physiological parameter, the physiological sensor comprising an emitter, a detector, a proximity sensor, and a drive, the emitter being configured to emit optical radiation at one or more wavelengths, the detector being configured to detect at least a portion of the optical radiation, the method comprising:
-
by the proximity sensor, detecting a distance between a patient and the proximity sensor, the distance being indicative of a position of the emitter or the detector relative to a measurement site of the patient; by one or more processors, generating, from the distance, instructions to adjust the position of the emitter or the detector relative to the measurement site; and by the drive, adjusting, according to the instructions, the position of the emitter or the detector relative to the measurement site. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41)
