    • A method for distinguishing erythroblasts from bacteria by automated hematology analyzers, such as, for example, the CELL-DYN® 4000 automated hematology analyzer and the CELL-DYN® Sapphire automated hematology analyzer. Bacterial cells scatter light and fluoresce differently than do red blood cells, white blood cells, erythroblast nuclei, and platelets. Signals generated by bacteria are distinguishable from those of erythroblasts because the signals generated by erythroblast nuclei are sufficiently unique that erythroblast nuclei can be distinguished from signals generated by bacteria. Signals generated by platelets, lysed red blood cell ghosts, and other cell debris are blocked by the triple-trigger circuitry of the hematology analyzer, because all of the signals generated by noise are below the AND/OR thresholds. Algorithm(s) in the software of the system detect and count signals generated by bacteria by means of the location and the shape of the signals generated by bacteria and calculate the concentration of bacteria per unit of body fluid. In addition, certain body fluids, such as, for example, synovial fluid, can be pretreated with a viscosity reducing agent for a short period of time to reduce the viscosity of the body fluid prior to analyzing a sample of the body fluid by an automated hematology analyzer.
    • 通过自动血液分析仪,例如CELL-4000自动血液分析仪和CELL-DYN®蓝宝石自动血液分析仪来区分成红细胞和细菌的方法。 细菌细胞散射光和发出不同于红血细胞,白血细胞,成红细胞核和血小板的荧光。 由细菌产生的信号与成红细胞产生的信号是可区分的,因为由成红细胞核产生的信号足够独特,可以将成红细胞核与细菌产生的信号区分开来。 因为由噪声产生的所有信号都低于AND / OR门限,所以血小板分析仪的三重触发电路会阻止血小板产生的信号,裂解的红血球重​​影和其他细胞碎片。 系统软件中的算法通过细菌产生的信号的位置和形状来检测和计数由细菌产生的信号,并计算每单位体液中细菌的浓度。 另外,某些体液,例如滑液,可以用粘度降低剂短时间预处理,以在通过自动化系统分析体液样本之前降低体液的粘度 血液分析仪。

    • The invention relates to a particle counter apparatus for counting particles in a fluid flowing in a pipe or a pipeline. The particle counter apparatus comprises a pipe portion through which the fluid flows, where the pipe portion is provided with a fluid sample outlet for withdrawal of a fluid sample. Furthermore the particle counter apparatus also comprises a first fluid transfer body extending from the fluid sample outlet to a particle counter, and a second fluid transfer body extending from the particle counter to a fluid return outlet mounted in the pipe portion downstream of the fluid sample outlet. In the pipe portion there is mounted a propeller unit comprising a propeller and a generator, with the result that particles are distributed uniformly in the fluid before the withdrawal of fluid samples, and electric power is provided for operation of the particle counter apparatus.
