    • PROBLEM TO BE SOLVED: To realize efficient capturing work of circulating cancer cells in blood by suppressing contamination of air into a flow path.SOLUTION: The capturing device for circulating cancer cells comprises a construction in which liquid to be supplied to a filter unit is selected by selection means and, based on the result, blood or processing solution is supplied to the filter unit by liquid supplying means, resulting in that efficient capturing work for circulating cancer cells in blood is performed when being compared to conventional device. In addition, a deaeration means is arranged at upstream side of the filter for capturing air in blood and discharging the air outside, thereby it is avoided that blood into which air is contaminated passes the filter, resulting in that reduction in processing efficiency due to air contamination is suppressed and high measurement precision may be maintained.
    • 要解决的问题:通过抑制空气进入流路的污染来实现血液循环癌细胞的有效捕获工作。解决方案:用于循环癌细胞的捕获装置包括其中选择供给到过滤器单元的液体 通过选择手段,根据结果,通过液体供给装置向过滤器单元供给血液或加工溶液,从而与常规装置进行比较,进行用于循环血液中的癌细胞的高效捕获工作。 此外,在过滤器的上游侧设置有除气装置,用于捕获血液中的空气并将空气排出到外部,从而避免被污染空气的血液通过过滤器,导致由于空气而导致的处理效率的降低 污染被抑制,并且可以保持高的测量精度。

    • PROBLEM TO BE SOLVED: To provide an inexpensive small-sized fluorescence measuring instrument improved in mechanical reliability.
      SOLUTION: The fluorescence measuring instrument is constituted so as to irradiate a sample with exciting light and to measure the fluorescence emitted from the fluorescent substance in the sample to measure the measuring target in the sample, and has: an exciting light source composed of a plurality of LEDs having different emission wavelengths; a wavelength selecting filter for exciting light which permits the transmission only of a specific wavelength component in the exciting light emitted from the exciting light source; a plurality of floodlight projecting fibers for transmitting exciting light to irradiate the leading end of the sample; a plurality of light detection fibers for detecting the fluorescence emitted from the sample; an optical fiber positioning holder for holding a light projecting and detecting part composed of the floodlight projecting fibers and the light detection fibers; a light detecting wavelength selecting filter for permitting the transmission of only the specific wavelength component in the detected fluorescence; and a light condensing fiber for bundling the transmitted light to one light quantity detector. The instrument is characterized by alternately lighting the exciting light source to measure the measuring target.
