    摘要: Disclosed is an apparatus and method for determining the liquid level of salvaged blood in a blood collection reservoir (11) of an autologous blood transfusion system (20), comprising sensing means (10, 12) for periodically sensing the liquid level of the salvaged blood in said blood collection reservoir (11) and outputting corresponding signals, and determining means (2) for determining the liquid level of the salvaged blood in said blood collection reservoir (11) based on said output signal of said sensing means. The sensing means comprises a plurality of light emitters (12) disposed on a first side of said blood collection reservoir (11) at different height levels (L1-L9) for emitting light and a plurality of light receivers (10) disposed at said different height levels (L1-L9) on a second side of said blood collection reservoir (11) opposite to said first side for sensing light emitted by said light emitters (12) and transmitted through said blood collection reservoir (11). Parameters of the optical set-up used for detection and signal analysis may be adjusted individually and dynamically so that disturbing effects caused e.g. by absorptive films on the inner surface of the blood collection reservoir (11) may be identified and prevented to thereby enhance the reliability of signal detection and analysis.

    摘要: A liquid surface level control method for an ion-exchange resin tower according to the present invention comprises steps of determining an operation signal (S18, S28, S38) of a discharge device of liquid (6) to be discharged from the ion-exchange resin tower (2a, 2b, 2c), based on a liquid surface level PID operation signal obtained by calculating a liquid surface level signal (S12) in a PID way and a supply flow rate signal (S10, S18, S28) supplied to the ion-exchange resin tower (2a, 2b, 2c), and moving the liquid surface level (6a) close to the target liquid surface level. Preferably, the interface level (4a) is detected by means of an interface level sensor (52), and the target liquid surface level is increased or decreased according to the increase/decrease of the interface level (4a). The interface level sensor (52) includes a plurality of light emitting parts and a plurality of light receiving parts which are opposite to each other in a one-to-one relation.

    摘要: A relative fullness of a fluid container is monitored by directing reference light at a bottom surface of the fluid container. The fluid container is designed so that the amount or pattern of reference light reflected from the fluid container varies in relation to the relative fullness of the fluid container. Accordingly, the relative amount or pattern of reference light reflected from the fluid container can be monitored and used to determine the relative fullness of the fluid container.

    摘要: Plural sensor prisms and associated opticalfiber circuits are arrayed as a single vertical stem by which the individual prisms serve for response to each of a plurality of different liquid levels. Each prism is formed of light-transmitting plastic material which can be injection-molded to precision dimensions. The body configuration is such as to adapt to arrayed interconnection with tubular members, also of plastic, and bonded at telescoping fit of each prism to the tubular member or members to which it is connected. The prism configuration relied upon for sensed response to the presence of immersing liquid (as compared to air) is a solid region having an exterior profile which includes a downwardly convergent conical surface portion at least at spaced locales which are at equal but opposite offset from the cylindrical body axis, wherein the geometric apex angle of downward convergence is 90 degrees. As long as a given prism is exposed to air, a large amount of light is transmitted (by reflection within the prism) from a transmission optical fiber to a receiving optical fiber. But when immersed in a liquid, a portion of the light from the transmitting fiber is refracted into the liquid, resulting in a clearly detectable decrease in the amount of light coupled to the receiving fiber.

    摘要: The invention relates to an optical probe comprising an optical means (5) having a given refractive index. This optical means is able to reflect an incident light beam if it is located in a medium (3), whose refractive index is higher than the given index and is able to reflect the incident light beam if it is in a medium (2), whose index is below the given index. The optical refraction or reflection means (5) is a cone of revolution, the axis (X) thereof being parallel to the incident beam (6) and to the optionally reflected beam (11), the base (12) of said cone receiving the incident light beam and is perpendicular to said incident light beam and to the possibly refracted beam. The cone and at least part of the optical fibres transmitting the incident and reflected light beams are located in a tight box or case. Application to the detection of interfaces of different media and to the determination of the components of a two-phase medium.
