  • Publication number: 20130310964
    Abstract: The sample transport system includes a management section which holds information on the status of a sample transport system as a whole as well as sample information in order to transport and control a plurality of carriers as a consecutive group and which generates group information on a group of carriers to be handled simultaneously based on sample attributes and request information; and units made up of a conveyer line, a connecting line, and a processing section to control received carriers at a converging point based on the group information, so as to permit group management control of the carriers. In this manner, the sample transport system processes as a single batch a plurality of samples collected for the same processing purpose.

  • Publication number: 20130202486
    Abstract: This invention provides a sample processing system in which only one sample container is rested in one holder, the system being contemplated to prevent a mix-up of samples from occurring. A barcode labeler module 13 includes an identifier-reading device R1 that reads an identifier of a holder holding a primary-sample container, a printer 13B that prints a label based on information from a control PC unit 21 as well as on the identifier of the primary-sample container holder that has been read by the identifier-reading device R1, and affixes the label to a secondary-sample container, and a second identifier-reading device R2 that reads an identifier of the holder having the secondary-sample container mounted therein.

  • Publication number: 20130201019
    Abstract: A laboratory automation system capable of reducing a wasting time of an operator work by giving a notification that enables a device state and a summary of an operator call to be recognized. The laboratory automation system having notifying means such as a display unit or a speaker which can be recognized by the operator distant from the device, includes a notifying unit for calling the operator, and a notifying unit for notifying a status of the device, in which a state device and a summary of the work conducted by the operator can be easily recognized by the combination of notifications of those notifying units.

  • Publication number: 20130197690
    Abstract: A method for controlling an automated sample test system includes a samples conveyance line for conveying samples racks, each holding samples, to a plurality of processing units, and an empty-rack stock section in which to stock samples racks not holding a sample. The control method is designed to collect information on whether the processing units are in need of a supply of empty samples racks, and then supply empty samples racks from the empty-rack stock section to the processing units based on the information. Decreases in throughput can be prevented by leveling the number of empty samples racks supplied to the processing units that require empty samples racks.

  • Publication number: 20120266698
    Abstract: Conventional conveying lines have required building according to the particular shapes of test tube racks and test tube holders. For this reason, at least two types of dedicated lines, one for test tube racks and one for test tube holders, have been needed in one system, so there has been a tendency for systems to be complex in structure and disadvantageous in cost. To solve these problems, this invention provides a sample conveying system designed so that test tube racks and test tube holders can move on the same line, and high in both cost-effectiveness and reliability.

  • Patent number: 8231843
    Abstract: Pressure fluctuations are sampled at fixed time intervals and subjected to arithmetic processing, using as a trigger the event (or a sign temporally close to that event) of the reverse motor rotation for the backlash correction, thereby discriminating normal suction from suction of sample liquid with undesirable air bubbles.

  • Publication number: 20120174687
    Abstract: After being dispensed, a sample that needs to be quickly measured passes through another unit and is transported to an automatic analyzer. A plurality of units are provided for functions of processing including a dispensing unit that dispenses the sample stored in a sample vessel into another sample vessel. At least one discharge line discharges the sample from the dispensing unit to a transport line and a line that is perpendicular to the discharge line. A reverse direction transport line transports the sample in a direction reverse to a direction in which the sample loaded in the system is transported to the dispensing unit. The sample that is processed by the dispensing unit is transported to a storage unit located on the upstream side of the system, through the reverse direction transport line.

  • Publication number: 20120177547
    Abstract: An empty rack transport line is arranged at a lower stage and independent of a main transport line, a fast emergency line and a reverse line. In a rack stocker, an inclined transport line connects the empty rack transport line to the rack stocker. The rack stocker is arranged between a storage module and a loading module. The rack stocker is capable of continuously supplying and collecting empty racks, while transport lines do not cross each other. It is, therefore, possible to continuously supply and collect empty racks in a simple configuration, without an increase in the size system, an intersection of transport lines and a reduction in processing capability. In addition, it is possible to provide an automated sample testing system that is highly extendable for a facility size.

  • Patent number: 7727469
    Abstract: In an automatic analyzer, when a sample is newly added, all sample barcodes on a sample disk are read. Immediately before dispensing it, second time reading is performed, and the result thereof is checked against that of the first time reading. A sample hand-contact preventing plate is provided above the reading position and dispensing position in order to prevent the sample from being exchanged after the second time reading. This hand-contact preventing plate has a damage-preventing configuration to protect a hand and fingers of an operator against a sampling probe.

  • Patent number: 7547414
    Abstract: For installing reagent bottles in a reagent disk, the operator needs to install them while confirming the orientation of each reagent bottle. However, the operator will groan under a psychological burden in working while confirming the orientation. If the operator installs a reagent cassette in wrong orientation, the result of measurement will be erroneous, possibly leading to a grave testing error particularly in a blood analyzer. An automatic analyzer comprises a recording medium for recording information on placement of a plurality of types of reagents contained in a single reagent container, a reagent container disk capable of carrying a plurality of the reagent containers, an information reader for reading information recorded on the recording medium, and a reagent dispense controller for controlling which of reagents is dispensed by a reagent dispenser based on the information read by medium information reader.
