    摘要: A noninvasive oximeter sensor for controlling and optimizing the minimum detection depth in the tissue of a patient is disclosed. In general, a minimum detection depth of 0.35 mm in the skin is considered optimum. The reflectance oximeter sensor component configuration of the present invention achieves the minimum detection depth. The present invention offers a more accurate indication of blood oxygen saturation in a patient's arterial blood than was available from previous reflectance oximeter sensors.

    摘要: A magnetically-levitated centrifugal pump, in which permanent magnets are not used for disposable sections, is provided with a pump head section and a pump section. The pump section comprises a stator, a torque transmission disc, a motor, a displacement sensor, and a pump housing. The stator has longer depth than protrusion length of a rotor accommodation section in which permanent magnets are not used, is equipped with a rotor insertion section, in which the rotor accommodation section is disposed so as to be able to be inserted and removed, on the side of one end section, and disposes three or more than three electromagnets for magnetic bearings, which magnetically couple with the rotor, at equal intervals. The torque transmission disc, which is disposed inside the rotor insertion section and which magnetically couples with the rotor, is formed by bonding ring components, which are made from magnetic material and are provided with protrusions at positions opposite protrusions on the rotor, between plural ring-shaped permanent magnets, which are magnetized in the thickness direction thereof, such that like-poles face each other, and then by placing another ring component on top of the uppermost ring-shaped permanent magnet. The motor rotationally drives the torque transmission disc. The displacement sensor measures radial displacement of the rotor.

    摘要: A cardiac function variation evaluation apparatus includes: a continuous flow type auxiliary artificial heart 20 connected to a ventricle (10A); a pressure sensor 30 for detecting ventricle (10A) internal pressure; and means (a personal computer 40) for evaluating contractile variation of the ventricle, to which the auxiliary artificial heart 20 is connected, based on internal area APMp of a closed-loop of a relationship between the ventricle internal pressure detected by the pressure sensor 30 and a consumption power of the auxiliary artificial heart 20. Thus, the contractile variation of the ventricle, to which an auxiliary artificial heart is connected, can be continuously evaluated not by use of an ultrasonic echo apparatus or a conductance catheter but by use of a non-invasive method.
