  • Publication number: 20180180636
    Abstract: A rinse mechanism rinses reaction cuvettes with first and second detergents. An R1 reagent pipetting mechanism 8 rinses the reaction cuvettes that have been rinsed by the rinse mechanism with a special detergent. A counting unit counts and stores in a storage unit a use frequency of each reaction cuvette for a specific reagent item. A determining unit determines whether the counted use frequency exceeds a predetermined threshold N1. A control unit controls the R1 reagent pipetting mechanism such that, in a case where the counted use frequency exceeds the predetermined threshold N1, the reaction cuvettes, which have exceeded the predetermined threshold N1, are soaked with the special detergent only for a period equal to or less than a value derived by multiplying a pipetting cycle time, which indicates a period when a sample is pipetted, by the total number of reaction cuvettes and a predetermined integer.

  • Publication number: 20180156702
    Abstract: When the type is to be changed from serum (preceding sample) to urine (current sample), “serum” is set to a preceding type and “urine” is set to a measurement type at number 1 in a condition number. At condition number 1, the wash type is pattern 1, with washing performed once with detergent 1. Where the preceding sample is serum and the current sample is CSF, the condition number is 2 and the wash type is pattern 2, with washing performed twice using detergent 1 and once with detergent 2. Where the preceding sample is urine and the current sample is CSF, the condition number is 3 and the wash type is pattern 3, with washing performed once with detergent 1, once with detergent 2, and once with water. In the case of pattern 4, washing is performed three times with detergent 1.

  • Patent number: 9945881
    Abstract: After an analysis start instruction is input in a state where a sample is not dispensed to all of reaction containers 104 mounted on a reaction disc 105, before completing an analysis preparation washing process for washing the reaction container 104 to be used in analyzing the sample to be first analyzed, a soaking and washing process for performing soaking and washing during a predetermined period of time is controlled to be started by dispensing a soaking and washing detergent to another reaction container 104 different from the reaction container 104. In this manner, the soaking and washing can be efficiently performed on the reaction container without hindering an analysis process.

  • Patent number: 9891241
    Abstract: An automatic analysis device in which a probe is washed in a short period of time and the amount of washing water which may be mixed in at the time of suctioning of a succeeding liquid can be decreased. Washing water is supplied to a throttle portion of a washing tank from a washing nozzle. A reagent probe is inserted into the washing tank. Washing of the outside of the reagent probe, washing of the throttle portion, and a washing operation for the inside of the reagent probe are performed while a lowering operation of the reagent probe is performed. The automatic analysis device is configured to perform a drying operation by using vacuum nozzles even when the reagent probe is lifted, and thus, washing and drying operations of the reagent probe can be sped up and can be performed in a short period of time.

  • Patent number: 9846170
    Abstract: To provide an automated analyzer adapted for accommodating a larger number of reagent cassettes to meet calls for increases in analytical throughput and in the number of analytical items, and thus using the accommodated reagent cassettes more efficiently. An automated analyzer body 100 includes a main reagent buffer 4 for storing a plurality of reagent cassettes each containing a reagent used for analysis and a subsidiary reagent buffer 12. A reagent cassette transfer 11 transfers the reagent cassettes from the main reagent buffer to the subsidiary reagent buffer, and vice versa. A control unit 200 operates so that when a reagent cassette that is not set in the main reagent buffer is to be used for an assigned analysis, the reagent cassette for the assigned analysis is transferred from the subsidiary reagent buffer to the main reagent buffer.

  • Patent number: 9772264
    Abstract: An automatic analyzer is capable of controlling the gap between the tip of the sample nozzle and the bottom surface of the reaction container and restricting the sample attached to the tip of the sample nozzle. A movement distance of an arm is calculated and stored while the tip of the sample nozzle contacts a coordinate measurement stand until a stop position detector detects a stop position detection plate. The sample nozzle is moved toward the bottom surface of the reaction container and is stopped at the time when the stop position detector detects the stop position detection plate. The arm is moved upwardly for the movement distance stored in memory from this position. The sample nozzle can be stopped such that the tip of the sample nozzle is contacted to the bottom surface of the reaction container and the bend (warp) of the sample nozzle is restricted.

  • Publication number: 20170219617
    Abstract: An automatic analyzing apparatus capable of obtaining an analysis result of a specimen high in urgency in a shorter time is provided. When a first rack 50 is present in a sampling line 103 and an analysis request for a second rack higher in the degree of urgency for analysis than the first rack 50 is detected, a control unit unloads the first rack 50 onto a transport line 100 through a return line 102, allows the first rack 50 to stand by at a rack standby position 120 on a transport line 101 between a loading line 101 and the return line 102 under control, and loads the second rack from the transport line 101 onto the sampling line 103 through the loading line 101 and transports the second rack to the dispensing position 111 under control while allowing the first rack 50 to stand by.

  • Patent number: 9709586
    Abstract: To provide an automatic analyzer which is not influenced by fluidity or viscosity of a sample, and which can stably dispense the sample with dispensing accuracy by determining whether a flow route including a sample probe is in a stable and suction-available state when the sample is suctioned. In suction of the sample, before the sample is suctioned, in the flow route including the sample probe, the automatic analyzer determines whether the sample is in a suction-available state or in a suction-unavailable state, and performs cleaning on the flow route when it is determined that the sample is not in the suction-available state. Since the state in the flow route including the sample probe is determined before the sample is suctioned, the automatic analyzer can repeatedly perform a dispensing operation having improved reliability, without being influenced by the fluidity or the viscosity.

  • Patent number: 9696331
    Abstract: The device uses a dispensing probe; a dispensing probe drive mechanism having at least one rotation drive shaft as a horizontal drive mechanism for the dispensing probe, a positioning member with a portion, which is contacted by the dispensing probe during positioning, is formed in a circular shape; a contact detection mechanism for detecting contact between the dispensing probe and the positioning member, and a control unit. The control unit drive-controls only one drive shaft into contact with the circular portion of the positioning member, and then drive-controls only one drive shaft other than the previously drive-controlled shaft into contact with the circular portion of the positioning member, and then calculates position information on a center point at a desired position where the dispensing probe is to be positioned, on the basis of position information on each point at which the contact has been detected, or the like.
