  • 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.

  • Patent number: 10292657
    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.

  • Publication number: 20140213864
    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.

  • Publication number: 20070295651
    Abstract: A disposable mass transfer system includes a source of dialysis fluid, a waste fluid reservoir, at least one semi-permeable tubular membrane residing in at least one fluid flow channel carrying a flow of a dialysis fluid, and a configurable pump and tubing. The pump and tubing may be configured to pump fresh dialysis fluid into the fluid flow channel, or may be configured to re-circulate partially spent dialysis fluid through the fluid flow channel. The fluid flow channel may be the interior of a flexible sealed reservoir, or may be a semi-rigid or rigid tubular enclosure.

  • Patent number: 7172696
    Abstract: A mass transfer device having a fluid permeable core wound with many stands of a hollow fiber. A bulk fluid enters the interior of the core, passes through the side wall of the core, and along the outer surfaces of the hollow fibers. A baffle positioned in the center of the core so that the bulk fluid passes outwardly upstream of the baffle and inwardly through the core along the downstream of the block.

  • Patent number: 6582955
    Abstract: A bioreactor having an outer shell compartment containing many coaxial pairs of hollow microporous fibers. An annular compartment exists between an outer surface of the inner hollow microporous fiver and the inner surface of the outer hollow microporous fiber. The annular compartment preferably contains blood or plasma. The blood or plasma is, thus, exposed to two microporous hollow fibers which have fluids which can purify or otherwise affect the blood through the walls of two different microporous hollow fibers. An artificial liver or kidney can result when liver or kidney cells are placed in the shell compartment.
