    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.

The device is characterized by a second supply system (10) for supplying a solution (18) to the separator (6) with a given flow rate. The flow rate of the solution (18) in the second supply system (10) during its supply to the separator (6) is determined based on the at least one process parameter.

    摘要: A tubing set for use in a blood processing apparatus comprises a measurement device (8) having at least one chamber element (80, 81) for measuring a haematocrit value of a blood fluid, wherein the at least one chamber element (80, 81) extends along a longitudinal axis (L) and comprises a circumferential wall (804, 814) extending about the longitudinal axis (L) and encompassing a flow chamber (802, 812), the at last one chamber element (80, 81) further comprising an inlet port (800, 810) for allowing a flow of a blood fluid into the flow chamber (802, 812) and an outlet port (801, 811) for allowing a flow of a blood fluid out of the flow chamber (802, 812). The tubing set furthermore comprises an inlet-side tube section (21, 31) connected to the inlet port (800, 810) and an outlet-side tube section (22, 30) connected to the outlet port (801, 811). Herein, the inlet port (800, 810) and the outlet port (801, 811) are arranged on the circumferential wall (804, 814) and are displaced with respect to each other along the longitudinal axis (L). In this way a tubing set comprising a measurement device is provided which in an easy and reliable manner allows for the measuring of a haematocrit value of a blood fluid.
