PROXIMITY SENSOR IN PULSE OXIMETER

摘要

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.

主权项

1. A physiological monitoring system comprising:
a sensor housing configured to at least accept a measurement site of a patient, the sensor housing comprising:
a first housing component including an emitter configured to at least emit light at one or more wavelengths when in use,a second housing component including a detector aligned with the emitter to detect at least a portion of the light, the detector configured to at least generate intensity signals representing detected light when in use, anda proximity sensor positioned on one or both of the first housing and the second housing; and a processor configured to at least:
receive data from the proximity sensor representing positioning of the measurement site relative to the proximity sensor, andbased at least partly on the data from the proximity sensor, determine positioning of the measurement site relative to the emitter and the detector.
