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.

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.

Abstract: In a case where a sample container 15 has a rubber-made lid 35, if a sample nozzle descends and comes into contact with the lid, the sample nozzle is relatively moved inside an arm as far as a lid detection distance, and a detector detects a detection plate. A fact that the sample nozzle comes into contact with the lid is stored together with position information of the sample nozzle, into an operation commanding unit. The sample nozzle further continues to descend, and a suction operation of a sample is performed at a predetermined position. In a case where the sample nozzle collides with a frame portion of the lid and external force is applied thereto, the detector detects that the detection plate is relatively moved as far as the detection distance.

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.

Abstract: A pressure sensor detects the inner pressure of a probe at the time of suction of a specimen and a memory stores therein a plurality of clogging detection parameters in accordance with pressure in the vacuum blood collection tube. The clogging detection parameter stored in the memory is selected in accordance with the pressure in the vacuum blood collection tube, and a determination of the clogging of the probe is performed based on the selected clogging detection parameter and the inner pressure at the time of suction of the specimen detected in the pressure sensor.

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.
