Abstract: A regional oximetry sensor has a sensor head attachable to a patient skin surface so as to transmit optical radiation into the skin and receive that optical radiation after attenuation by blood flow within the skin. The sensor includes windows that press into the skin to maximize optical transmission. A stem extending from the sensor head transmits electrical signals between the sensor head and an attached cable. In a peel resistant configuration, the stem is terminated interior to the sensor head and away from a sensor head edge so as to define feet along either side of the stem distal the stem termination. The stem interior termination transforms a peel load on a sensor head adhesive to less challenging tension and shear loads on the sensor head adhesive.

Abstract: An ear sensor provides physiological parameter monitoring. The ear sensor may comprise an in-ear portion configured to fit in an ear of a user. The in-ear portion may include at least one light emitter configured to emit light into an ear tissue site of the user and at least one light detector configured output a signal responsive to at least a portion of the emitted light after attenuation by ear tissue of the ear tissue site.

Abstract: A multiple wavelength optical sensor has an emitter configured to radiate light having a plurality of wavelengths into a tissue site. The emitter comprises a plurality of LEDs configured in an array and connected within an electrical grid. A detector is configured to receive the light after absorption by pulsatile blood flow within the tissue site. The detector generates a sensor signal capable of being processed by a patient monitor so as to derive oxygen saturation, carboxyhemoglobin, methemoglobin and total hemoglobin.

Abstract: Because reprocessing or refurbishing of physiological sensors reuses large portions of an existing sensor, the material costs for refurbishing sensors is significantly lower than the material costs for making an entirely new sensor. Typically, existing reprocessors replace only the adhesive portion of an adhesive physiological sensor and reuse the sensing components. However, re-using the sensing components can reduce the reliability of the refurbished sensor and/or reduce the number of sensors eligible for refurbishing due to out-of-specification sensor components. It is therefore desirable to provide a process for refurbishing physiological sensors that replaces the sensing components of the sensor. While sensing components are replaced, generally, sensor cable and/or patient monitor attachments are retained, resulting in cost savings over producing new sensors.

Abstract: An ear sensor provides a sensor body having a base, legs extending from the base and an optical housing disposed at ends of the legs opposite the base. An optical assembly is disposed in the housing. The sensor body is flexed so as to position the housing over a concha site. The sensor body is unflexed so as to attach the housing to the concha site and position the optical assembly to illuminate the concha site. The optical assembly is configured to transmit optical radiation into concha site tissue and receive the optical radiation after attenuation by pulsatile blood flow within the tissue.
