  • Publication number: 20150104351
    Abstract: A high-throughput automatic analyzer integrates a biochemical analysis section and a blood coagulation analysis section. The analyzer is capable of achieving a reduction in size, system cost, and lifecycle cost. The automatic analyzer includes: a reaction disk; a first reagent dispensing mechanism that dispenses a reagent to reaction cells on the reaction disk; a photometer that irradiates a reaction solution in the reaction cell with light; a reaction cell cleaning mechanism; a reaction vessel supply unit that supplies a disposable reaction vessel for mixing and reacting a sample and a reagent with each other; a second reagent dispensing mechanism that dispenses a reagent to the disposable reaction vessel; a blood coagulation time measuring section that irradiates a reaction solution in the disposable reaction vessel with light to detect transmitted or scattered light; and a sample dispensing mechanism that dispenses a sample to the reaction cell and the disposable reaction vessel.

  • Patent number: 8858882
    Abstract: There is provided a data processing method that reduces influences of air bubbles and dirt while maintaining changes in light amounts. Two scattering light photoreceivers are disposed in the forward direction. A photoreceiver 33a closer to the optical axis is taken to be a main angle photoreceiver, and a photoreceiver 33b further from the optical axis is taken to be a sub-angle photoreceiver. Noise is estimated based on the reaction process data of the sub-angle photoreceiver, and noise is reduced by subtracting the estimated noise from the reaction process data of the main angle photoreceiver.

  • Publication number: 20140241945
    Abstract: An automatic analysis device has a light scattering photometer incorporated therein, and improved accuracy resulting from reducing the influences from external light. The automatic analysis device includes a scattered light measurement unit disposed inside the main-body casing, and openable/closable protective covers to cover the top face of the main-body casing. A first protective cover at the center includes a light-shielding part to block external light. The protective covers include see-through parts enabling viewing of the inside. The light-shielding part is configured to cover an area of the reaction disk at least corresponding to the area above the scattered light measurement unit, thus reducing external light leaking into the scattered light measurement unit, and thus removing influences from external light on the scattered light measurement. The protective cover may have a divided structure.

  • Publication number: 20140220705
    Abstract: An analyzer provides conditions suitable for a reagent for performing latex immunoassay with a high sensitivity using a method of measuring scattered light. Irradiation light having a wavelength in the range of 0.65 to 0.75 ?m is used, and scattered light generated from a reaction solution is received at a light-receiving angle of 15° to 35° with respect to the irradiation direction during the rotational movement of the reaction container. The reagent contains latex particles the average peak particle diameter of which ranges from 0.3 ?m to 0.43 ?m and to which antibodies are sensitized. The reaction solution contains latex particles at a concentration at which the absorbance to irradiation light having a wavelength of 0.7 ?m is 0.25 abs to 1.10 abs, and a change in the amount of scattered light caused by the aggregation of the latex particles through antigens in a sample is measured and quantified.

  • Publication number: 20140140890
    Abstract: The automatic analysis device measures time sequential data on a scattered light amount as reaction process data, and quantitatively determines the concentration of an analyte from a change in light amount. The automatic analysis device has a function of selecting reaction process data to be used for quantitative determination from the reaction process data obtained by measurement using a plurality of light receivers at different angles. As a result of using this function, data is selected from the reaction process data obtained by measurement using the plurality of light receivers at different angles in accordance with the concentration of the analyte and whether the priority is given to high sensitivity in the case where sensitivity is prioritized or a dynamic range, and the result of the quantitative determination is displayed.

  • Patent number: 8725932
    Abstract: A first log indicating that a system is running is recorded in a second storage unit before a first difference log is recorded in the second storage unit after system startup, and a second log indicating that the system halts is recorded in the second storage unit following the difference log, at the time of normal system halt, and it is judged whether normal system halt has been performed or an incorrect power-off sequence has been performed last time, based on a recorded state of the first and second logs in the second storage unit, at the time of system startup, thereby detecting an incorrect power-off easily and reliably.

  • Patent number: 8706988
    Abstract: A memory system comprising a volatile memory unit, a nonvolatile memory unit, and a controller that performs data transfer between a host system and the nonvolatile memory unit via the volatile memory unit stores management information including a storage position of the data stored in the nonvolatile memory unit during a startup operation into the volatile memory unit, and performs, while updating stored management information, data management in the volatile and nonvolatile memory units based on the stored management information. The nonvolatile memory unit includes a snapshot storing area storing a snapshot which is the management information stored in the volatile memory unit at a certain point, a main log storing area storing a main log which is an update information of the management information stored in the volatile memory unit, and a backup log storing area storing a backup log having contents same as contents of the main log.

  • Publication number: 20130302212
    Abstract: The invention provides an automatic analyzer having a scattered-light detecting optical system in which a light source is disposed at an angle with respect to a plane of a reaction vessel. This reduces the amount of a sample-reagent mix required for an analysis, thereby reducing the running cost of reagents as well, and also allows relatively free design of reaction vessels in terms of their sizes and shapes. The automatic analyzer includes: a reaction vessel in which a sample is caused to react with a reagent; a reaction disk on which to place reaction vessels in the form of a circle; a reaction disk rotating mechanism for rotating the reaction disk; a light source for radiating light to be measured onto one of the reaction vessels; and a photodetector for detecting transmissive light radiated from the light source and passing through a sample-reagent mix in the one of the reaction vessels.
