  • Publication number: 20200323472
    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.

  • Publication number: 20200163598
    Abstract: A regional oximetry sensor can have a sensor head configured to secure to skin of a user and a stem extending from the sensor head. The sensor head can include an emitter configured to transmit optical radiation into the skin and at least one detector configured to receive the optical radiation after attenuation by blood flow within the skin. The stem can be configured to transmit electrical signals from the sensor head to a cable. A plurality of notches can extend from a perimeter of the sensor head towards an interior thereof. The plurality of notches can form a plurality of independently flexible cutouts in the sensor head configured to allow for movement of at least a portion of the skin of the user underlying the sensor head when the regional oximetry sensor is in use.

  • Patent number: 10617335
    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.

  • Publication number: 20190231270
    Abstract: An physiological measurement device provides a device 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 device body is flexed so as to position the housing over a tissue site. The device body is unflexed so as to attach the housing to the tissue site and position the optical assembly to illuminate the tissue site. The optical assembly is configured to transmit optical radiation into tissue site tissue and receive the optical radiation after attenuation by pulsatile blood flow within the tissue.

  • Publication number: 20180082767
    Abstract: An automated assembly sensor cable has a generally wide and flat elongated body and a registration feature generally traversing the length of the body so as to identify the relative locations of conductors within the body. This cable configuration facilitates the automated attachment of the cable to an optical sensor circuit and corresponding connector. In various embodiments, the automated assembly sensor cable has a conductor set of insulated wires, a conductive inner jacket generally surrounding the conductor set, an outer jacket generally surrounding the inner jacket and a registration feature disposed along the surface of the outer jacket and a conductive drain line is embedded within the inner jacket. A strength member may be embedded within the inner jacket.
