Medical sensors configured to provide enhanced patient comfort when worn over a period of time are provided. The medical sensors may include a first padding layer and a second padding layer disposed on either side of an emitter and a detector for measuring a physiological parameter of a patient. The medical sensors may also include an island padding layer secured to a patient-facing side of the second padding layer for reducing localized pressure points that may be caused by protrusions of the sensor. Additionally or alternatively, certain edges of the sensors may be rounded and/or stepped to reduce marking on the patient's tissue and to reduce strain and shear forces produced on the patient's tissue. Still further, certain embodiments provide enhanced light transmission between the emitter and detector of the sensors.

Medical sensor for use with headband

The present disclosure is generally directed to maintaining sensor quality standards and/or preventing improper remanufacture of sensors, such as pulse oximetry sensors. Present embodiments may include a system for facilitating the monitoring of physiologic conditions that includes an optical reader configured to translate an optical machine-readable representation of data associated with a patient into electronic data, a memory device configured to receive and store the electronic data after an initial reading of the machine-readable representation of data by the optical reader, and a processor configured to associate the electronic data with historical data obtained from the patient and limit access to the historical data based on whether the optical reader provides matching electronic data based on a subsequently read optical machine-readable representation of data when predefined conditions are met.

System and method for linking patient data to a patient and providing sensor quality assurance

Headbands configured to provide pressure against a medical sensor secured to a patient's forehead are provided. The headbands may include one or more low friction materials to enable an elastic band of a tensioning mechanism to evenly stretch. Additionally or alternatively, the headbands may include two or more bands adapted to secure the headband to various portions of a patient's head. Still further, the headbands may be configured to independently vary the pressure created between two or more sensors and the patient's head.

Headband for use with medical sensor

The present disclosure relates to sensors for use on a patient's ear. The sensors as provided may be Y-shaped and configured to be retained on an ear with the forks of the Y-shape positioned below the main branch of the Y. In particular embodiments, the Y-shaped sensors may be affixed to the patient at locations on the head or neck to relieve strain and reduce the effects of motion on the optical components of the sensor.

Y-shaped ear sensor with strain relief

A physiological sensor includes an emitter configured to transmit light and a detector configured to receive the transmitted light. The sensor also includes a first accelerometer disposed on a first portion of the sensor and a second accelerometer disposed on a second portion of the sensor, the second portion opposing the first portion. The first and second accelerometers are configured to measure a change in motion that corresponds to a change in distance between the detector and the emitter.

Motion compensation in a sensor

The present disclosure relates to sensors for use on a patient's ear. The sensors as provided may be disposable and configured to be retained on an ear with a biasing mechanism. In particular embodiments, the biasing mechanism is a sliding clip that is configured to bias a first portion and a second portion of a sensor body towards one another.

Flexible bandage ear sensor

The present disclosure relates to sensors for use on a patient's ear. The sensors as provided may include a moldable member, such as a putty. The moldable member may be molded in place to affix the optical components of the sensor to a patient's ear tissue. For example, the moldable member may be sculpted around a curvature of a patient's earlobe. In particular embodiments, the moldable member may be activated, e.g., hardened, by exposure to particular temperatures or by exposure to light.

Moldable ear sensor

The present disclosure is generally directed to maintaining sensor quality standards and/or preventing improper remanufacture of sensors, such as pulse oximetry sensors. Present embodiments may include a sensor that includes an optical machine-readable representation of data included on the sensor and/or packaged therewith, and an information element configured to store data corresponding to the data represented by the optical machine-readable representation.

System and method for providing sensor quality assurance

A system and method for compensating for movement in a sensor. A sensor may include an emitter configured to transmit light, a detector configured to receive the transmitted light via a respective light path, and an accelerometer configured to measure a change in distance between the detector and the emitter. The sensor may transmit the measurements relating to the change in distance between the detector and the emitter to a pulse oximetry monitor. The pulse oximetry monitor may generate an attenuation factor corresponding to the change in the distance between the detector and the emitter that may be used to compensate for movement in a sensor when calculating physiological parameters of a patient.

A system includes a flexible sensor configured to be placed into a first configuration and a second configuration, wherein the sensor is configured to measure a physiological characteristic. The sensor may include a first memory device configured to store a first set of calibration data and a second memory device configured to store a second set of calibration data. The system may further include a monitor coupled to the sensor, wherein the first memory device is accessible by the monitor in the first configuration and the second memory device is accessible by the monitor in the second configuration.
