  • Patent number: 6811753
    Abstract: A blood testing tool is provided, which separates blood cells and can collect blood plasma or blood serum with a high yield. The blood testing tool includes an asymmetric porous membrane with a pore size distribution in which an average pore size varies to be reduced continuously or discontinuously in a thickness direction. The porous membrane includes a blood supply portion, a development portion, and a blood-cell blocking portion formed between the blood supply portion and the development portion and pores in the blood cell blocking portion include only pores through which blood cells cannot pass. When blood is supplied to one side with larger pores of the blood supply portion, the blood moves in a direction parallel to a surface of the porous membrane by a capillary phenomenon, but only blood plasma or blood serum moves into the development portion to develop.

  • Patent number: 5038021
    Abstract: An analyzng device comprises a plate holding table, a shifting mechanism for shifting the plate holding table, bar code reading sensors, and a detecting unit for detecting the signals based on the drops of the solutions in the plate set on the plate holding table located in the plate measurement position. When the data of the bar code read by the bar code reading sensor is not fit for a predetermined measurement condition, the plate holding table is shifted to the plate exhausting position. On the other hand, when the data of the bar code is fit for the predetermined measurement condition, the plate holding table is shifted to the solution pipetting position and when the pipetting of the solutions is finished, the plate holding table is further shifted to the mesurement position. When the concentration of substance in the test solution is completed by the detecting unit, the plate holding table is shifted to the plate exhausting position.

  • Patent number: 4585007
    Abstract: A method for accurately performing concentration measurements while compensating the dilution ratio as needed during continuous measurement of specified ingredient in the liquid to be tested. The liquid to be tested is diluted by a diluent, wherein the liquid to be tested and the diluent or the mixture of the two and the diluent is transferred by means of the respective tube pumps to a measuring section. Either or both of the quantities of liquid-feeding of those two liquids are changed at the beginning of measuring or in an optional stage during the time of the measurement, diluted and mixed at two or more dilution ratios. Then the real dilution ratio at the time of changing the quantities of the said liquids is found on the basis of the measured value of the substance to be measured at the respective dilution ratios, and the concentration of the substance contained in the liquid to be tested is determined by using the real dilution ratio.

  • Patent number: 4512348
    Abstract: At the time of drawing the blood continuously from the vein of the patient by means of a catheter and measuring the concentration of a specified constituent part contained in the blood automatically and continuously for long hours, the sample liquid and two sorts of correcting liquids (standard liquid I and base liquid) are sucked by a single sampling nozzle in prescribed order and are supplied to the measuring section through a common channel. Each of the liquids are diluted with a buffer solution at the identical rate with the manifold in the measuring section, are separated from one another through the interposition of air layers among them, and supplied to a sensor. The outputs of the measured sample liquid from the sensor are corrected by the outputs of each of the neighboring measured correcting liquids in succession and are displayed as measured values.
