Abstract
According to embodiments, a headcovering hat-based, and/or headband sensor assembly may provide an output to indicate when the sensor experiences abnormal forces or pressure. The sensor assembly may include features to increase the pressure against the tissue to allow the sensor to contact the tissue with sufficient force to obtain accurate measurement, but not so much force as to cause any discomfort for a patient.
Claims20
An apparatus comprising:
- a headcovering capable of being applied to a patient's head;
- a substrate disposed on the headcovering;
- an emitter disposed on the substrate;
- a detector disposed on the substrate;
- a cable extending from the substrate through an open portion of the headcovering configured to be proximate to a top of the headcovering when the headcovering is applied to the patient;
- and
- a pressure sensor associated with the headcovering, wherein the pressure sensor is capable of providing a pressure indication.
4 more elements
A pulse oximetry system comprising:
- a pulse oximetry monitor;
- and
- a sensor assembly capable of being operatively coupled to the monitor, the sensor assembly comprising:
- a headcovering capable of being applied to a patient's head;
- a substrate disposed on the headcovering;
- an emitter disposed on the substrate;
- a detector disposed on the substrate;
- a cable extending from the substrate through an open portion of the headcovering, configured to be proximate to a top of the headcovering when the headcovering is applied to the patient;
- and
- a pressure sensor associated with the headcovering, wherein the pressure sensor is capable of providing a feedback to the monitor.
7 more elements
A method comprising:
- emitting light into a tissue with an emitter;
- detecting the light with a detector;
- measuring a physiological characteristic based at least in part upon the detected light;
- detecting a force experienced by at least one of the emitter and the detector with a force-sensitive sensor;
- and
- adjusting the position of the emitter and the detector against the tissue with a tightening structure when the force is outside of a predetermined range.
