  The automatic analyzer dispenses the test sample and the reagent into the reaction cell, and measures the reaction change (change in absorbance) between the test sample and the reagent, thereby determining the component amount of the component corresponding to the reagent. Measure. For example, FIG. 10 is a perspective view showing a schematic configuration of a main part of a conventional automatic analyzer. After the test sample is collected from the specimen, it is stored in the test sample container and placed on the sample disk 101. Reagents are stored in reagent bottles and placed in reagent containers 102 and 103. On the other hand, the reaction cell is arranged on the reaction disk 104.

  Therefore, a sample probe 105 for dispensing from a sample container placed on the sample disk 101 to a reaction cell placed on the reaction disk 104 is provided, and from the reagent bottle placed in the reagent storage 102, 103 to the reaction disk 104. Reagent probes 106 and 107 for dispensing into the arranged reaction cells are provided.

  The sample probe 105 is fixedly supported by a sample arm 108, and reciprocates between the sample disk 101 and the reaction disk 104 by the rotation of the sample arm 108. The reagent probes 106 and 107 are fixedly supported by the reagent arms 109 and 110, and the reagent arms 109 and 110 are reciprocated between the reagent storages 102 and 103 and the reaction disk 104 by the rotation of the reagent arms 109 and 110. ing. Each probe 105-107 moves up and down by an elevating mechanism provided in each arm 108-110, respectively.

  Dispensing with these probes 105 (-107) is performed by first moving the sample disk 101 to the test sample container (or the reagent bins of the reagent storages 102 and 103), and the test sample container (or reagent bin). Aspiration operation, movement from the sample container of the sample disk 101 (or reagent bins of the reagent storages 102 and 103) to the reaction cell of the reaction disk 104, discharge operation in the reaction cell, and from the reaction cell of the reaction disk 104 to the washing position , Movement of the inside and outside of the probe 105 (˜107), movement of the sample disk 101 to the sample container (or reagent bin of the reagent storage), and so on, many steps (operations) must be passed. There was a problem that dispensing took time.

  Therefore, in order to reduce the time required for these dispensings, some conventional automatic analyzers use a plurality of probes and dispense a plurality of items at the same time. That is, a plurality of probes are fixed in a bundle, inserted into one sample container (or reagent bottle), and simultaneously suctioned.

  For example, as shown in FIG. 11, four sample probes 121 to 124 are used. The four sample probes 121 to 124 are inserted into one test sample container 125 on the sample disk (inserted by descending), and simultaneously a suction operation is performed, and then moved onto the reaction disk 104, A test sample is dispensed into four reaction cells 126 to 129.

  However, since the number of items to be measured with respect to the test sample is not necessarily a multiple of four, as shown in FIG. The sample probes 121 to 124 are inserted into one test sample container 125, but only the two sample probes 121 and 123 perform the suction operation at the same time, and the other two sample probes stop the suction operation. Thereafter, the sample is moved onto the reaction disk 104, and the two sample probes 121 and 123 dispense the test sample into the two reaction cells 126 and 128.

  In addition, as shown in FIG. 13, two reagent probes 131 and 132 and two reagent bottles 133-1, 133-2, 134-1, 134-2, and 135-1 arranged in two rows as one set. , 135-2, 136-1, 136-2,... The two reagent probes 131 and 132 are inserted into one set facing each other in a row, here, the first set of reagent bottles 133-1 and 133-2 (inserted by descending), and at the same time perform the suction operation. Then, it moves onto the reaction disk 104 and dispenses each reagent into the two reaction cells 141 and 142. That is, the reagent probe 131 dispenses the reagent in the reagent bottle 133-1 into the reaction cell 141, and the reagent probe 132 dispenses the reagent in the reagent bottle 133-2 into the reaction cell 142.

  However, since the reagents in the reagent bottles that are always in pairs are not always used, depending on the measurement item of the test sample, the two reagent probes 131, In some cases, only one reagent probe out of 132 performs the aspiration operation / dispensing, and the other reagent probe stops the aspiration operation and does not perform dispensing.

  As described above, the conventional automatic analyzer has a problem that even if a plurality of probes are used, all of the plurality of probes may not be used effectively depending on the number and contents of measurement items of the test sample. It was. If all of the probes cannot be used effectively, there is a problem that the initial purpose of shortening the dispensing time cannot be achieved.

  Accordingly, an object of the present invention is to provide an automatic analyzer that can effectively use a plurality of probes to be dispensed and can shorten the dispensing time.

The automatic analyzer according to the first aspect of the present invention detects a reaction between a test sample and a reagent dispensed in a reaction vessel arranged on the circumference of a reaction disk, and detects the reaction based on the detection result.

  In the first embodiment having such a configuration, sampling processing is performed by the CPU 21 as shown in FIG. First, as the processing in step 1 (ST1), the number of measurement items already set for the sample (test sample to be analyzed (measured) from now on) is set in the storage area T formed in the RAM 23.

  Next, as a process of step 2 (ST2), it is determined whether or not the numerical value T set in the storage area T is 2 or more. Here, if it is determined that the numerical value T is less than 2, it is determined whether or not the numerical value is 1 as processing of step 3 (ST3).

  If it is determined that the numerical value T set in the storage area T is 2 or more in the processing of step 2 described above, both sample probes 6 and 7 are connected to the samples on the sample disk 2 as processing of step 4 (ST4).

Set to. Next, as a process of step 10 (ST10), a subtraction update process of -1 is performed on the numerical value T set in the storage area T, and the process returns to the above-described process of step 2 again.

  If it is determined that there is no sample to be analyzed next in the process of step 6 described above, both the first sample probe 6 and the second sample probe 7 are used as the sample of the sample disk 2 as the process of step 11 (ST11). Only one of the sample probes (one selected according to the position of the sample container of the sample) performs the suction operation, and the other stops the suction operation. Then, the test sample is dispensed into one reaction cell of the reaction disk 1 with only one of the sample probes, and this sampling process is terminated.

  If it is determined in step 3 above that the numerical value T set in the storage area T is not 1 (0), it is determined in step 12 (ST12) whether there is a sample to be analyzed next. to decide. Here, if it is determined that there is a sample to be analyzed next, a transition process using the next sample as the sample is performed as the process of step 13 (ST13), and the process returns to the above-described step 1 again. . When it is determined that there is no sample to be analyzed next, the sampling process is terminated.

  For example, when the number of measurement items is 5 for the sample (test sample) A and there is a next sample B, first, in the first sampling, the dispensing for the first and second items is the sample probe 6. , 7 at the same time. In the second sampling, dispensing for the third and fourth items is simultaneously performed by the sample probes 6 and 7. In the third sampling, dispensing of the fifth item and the first item of the specimen B is performed by the sample probes 6 and 7.

  When one of the sample probes 6 and 7 stops the aspirating / dispensing operation, it is only when one unmeasured item remains for the last sample (no next sample).
