  In step S <b> 1-1, the CPU 200 a controls the measurement device 2 to execute initial setting processing. In the initial setting process, a process of returning each unit to the initial position is executed. Further, the CPU 200a controls the cuvette supply unit 208 to supply the cuvette 217 to the cuvette storage unit 208a, and transfers the cuvette 217 stored in the cuvette storage unit 208a to the second table unit 207 and the cuvette table 206c, respectively. One catcher unit 209 and the second catcher unit 211 are controlled.

  When the initialization process is completed, the CPU 200a executes a process of waiting for reception of the measurement start signal transmitted from the CPU 301a in step S1-2.

  On the other hand, in step S2-1, the CPU 301a controls the information processing apparatus 3 to execute initial setting processing. In the initial setting process, a process such as initialization of software stored in the hard disk 301d or the like is executed.

  When the initialization process is completed, the CPU 301a executes a process of waiting for an input of a measurement start instruction from the operator in step S2-2. When a measurement start instruction is input from the operator (YES in step S2-2), CPU 301a executes a process of transmitting a measurement start signal to measurement device 2 in step S2-3.

  On the other hand, when the measurement start signal is received (YES in step S1-2), the CPU 200a causes the transfer device 201 to transfer the rack 404 set in the rack set area A to the barcode reading position 201c in step S1-3. Execute the process to be controlled.

  Next, in step S1-4, the CPU 200a reads the barcode 405 attached to the rack 404 conveyed to the barcode reading position 201c and the barcode 402 attached to the sample container 401 held in the rack 404. A process for controlling the barcode reader unit 202 is executed.

  Next, in step S1-5, the CPU 200a executes a process of transmitting the barcode 402 read by the barcode reader unit 202 and the identification information included in the barcode 405 to the CPU 301a.

  Here, the identification information included in the barcode 402 and the barcode 405 will be described. The bar code 402 includes sample identification information for identifying the sample stored in the sample container 401. The specimen identification information is set in a serial number format such as C001, C002, C003,. The bar code 405 includes rack identification information for identifying the rack 404. The rack identification information is set in the serial number format of R001, R002, R003,. Further, the CPU 200 a transmits to the information processing apparatus 3 a container position indicating which holding unit 404 a of the rack 404 holds the sample container 401. The container position is represented by an integer of sequential numbers such as 1, 2,..., 9, 10, and each number is assigned to each container position.

  On the other hand, in step S2-4, the CPU 301a executes a process of waiting for reception of identification information from the CPU 200a.

A process for inquiring the measurement order to the host computer in which the measurement order is registered is executed.

  FIG. 14 shows the measurement orders registered in the host computer in tabular form. Registration of the measurement order in the host computer is performed by the operator of the sample analyzer 1 before analyzing the sample by the sample analyzer 1. As shown in FIG. 14, in the measurement order, rack identification information, container position, sample identification information, measurement item, and retest schedule are associated and registered. The measurement item is represented, for example, as “Fbg” for a sample that measures fibrinogen and “PT” for a sample that measures pron thrombin time. The re-examination schedule is “Yes” when the sample accommodated in the sample container 401 is a sample to be re-examined as necessary, and “None” when the sample is not to be executed. Is set.

Here, the CPU 301a executes a process of transmitting either the combination of the identification information of the rack 404 and the container position or the identification information of the sample container 401 to the host computer. When the host computer receives the combination of the identification information of the rack 404 and the container position or the identification information of the sample container 401, the host computer executes a process of transmitting the corresponding measurement item and retest schedule to the CPU 301a. For example, in step S2-5, it is assumed that the CPU 301a performs a process of transmitting information for identifying a specimen “rack identification information is C001 and container position is 1” to the host computer. In that case, the host computer refers to the measurement order shown in FIG. 14 and executes a process of transmitting information “the measurement item is Fbg and there is no reexamination schedule” to the CPU 200a.

  When the re-examination schedule is “none” in step S1-7, the CPU 200a executes measurement in the first operation mode in step S1-8. On the other hand, if the re-examination schedule is “Yes” in step S1-7, the CPU 200a executes measurement in the second operation mode in step S1-9. Here, the measurement in the first operation mode is a measurement process including a process of dispensing an amount of sample that can be measured once for one measurement item from the sample container 401. The measurement in the second operation mode is a measurement process including a process of dispensing an amount of sample that can be measured multiple times for one measurement item from the sample container 401. Details of the measurement processing in the first operation mode and the second operation mode will be described later.

  Next, in step S1-11, the CPU 200a executes a process of determining whether or not the measurement of the samples stored in all the sample containers 401 held in the rack 404 has been completed. When the measurement of all the samples held in the rack 404 has not been completed (NO in step S1-11), the CPU 200a executes the process of step S1-7 again.

  When the measurement of the samples stored in all the sample containers 401 held in the rack 404 has been completed (YES in step S1-11), the CPU 200a stores the sample for which the measurement has been completed in step S1-12. The third catcher unit 213 and the second catcher unit 211 are configured to drop the cuvette 217 held by the detection unit 216 and the cuvette 217 held by the cuvette table 206c into the cuvette disposal hole 219a and the cuvette disposal hole 219b, respectively.

At the same time, the CPU 200a executes a process of controlling the transport unit 201 so that the rack 404 in the transport area B is transported to the rack storage area C.

  On the other hand, in step S2-8, the CPU 301a executes a process of waiting for reception of the measurement result transmitted from the CPU 200a. When the measurement result is received (YES in step S2-8), the CPU 301a executes measurement result analysis processing in step S2-9.

  Next, in step S2-10, the CPU 301a executes processing for determining whether or not there is a shutdown instruction from the operator. If there is a shutdown instruction (YES in step S2-10), the CPU 301a transmits a shutdown instruction to the measurement apparatus 2 and executes processing for shutting down the information processing apparatus 3 in step S2-11. When there is no shutdown instruction (NO in step S2-11), the CPU 301a executes the process of step S2-2 again.

  On the other hand, when the measurement target rack 404 is not in the rack set area A (YES in step S1-12), the CPU 200a executes a process of determining whether or not a shutdown instruction from the CPU 301a has been received in step S1-13.

Is done. Then, the pipette 220a is transferred to the detection unit 216, and the specimen stored in the pipette 200a is measured.

  Further, the measurement apparatus 2 may be provided with an emergency sample setting unit for setting a sample container 401 in which a sample to be preferentially analyzed is stored. FIG. 17 is a schematic view of the measurement apparatus 2 including the emergency sample setting unit 221. As illustrated in FIG. 17, when the sample container 401 is installed in the emergency sample installation unit 221, the CPU 200 a interrupts the suction of the sample from the sample container 401 held in the rack 404 at that time, and sets the emergency sample installation. A process of controlling the second dispensing unit 205 to dispense a sample from the sample container 401 installed in the section 221 to the cuvette 217 on the second table unit 207 is executed. Thereafter, the CPU 200a executes steps S3-6 to S3-17.

  In the above embodiment, the CPU 200a selects whether to perform the measurement in the first operation mode or the measurement in the second operation mode based on whether or not the re-examination schedule is included in the measurement order. You may select which operation mode to perform measurement based on other conditions.

  For example, information indicating whether or not the sample container 401 has the lid 403 is included in the measurement order, and based on the information, the CPU 200a may select which operation mode to perform the measurement. Here, the CPU 200a performs measurement in the first operation mode when the lid 403 is attached to the sample container 401, and performs measurement in the second operation mode when the lid 403 is not attached. The measuring device 2 is controlled. In the measurement in the second operation mode, the CPU 200a controls the first dispensing unit 204 so as to dispense the sample more than the amount required for one measurement. By doing in this way, the sample accommodated in the sample container 401 without the lid 403 can be immediately aspirated quantitatively. In addition, a sample contained in a sample container equipped with a lid 403 such as a vacuum blood collection tube is also dispensed by the first dispensing unit 204 after being dispensed by the first dispensing unit 204 in an amount larger than that required for one measurement. Since the quantitative dispensing is performed by the two-dispensing unit 205, for example, the quantitative suction can be performed without requiring a complicated operation of releasing the internal pressure and then performing the quantitative suction. Therefore, even when the sample container 401 with the lid 403 and the sample container 401 without the cover 403 are mixed, the examination can be performed quickly.

  In addition, information on the amount of sample contained in the sample container 401 is included in the measurement order, and based on the information, the CPU 200a may select which operation mode to perform measurement. Here, the CPU 200a performs measurement in the second operation mode when the amount of the sample accommodated in the sample container 401 is equal to or larger than the predetermined amount, and performs measurement in the first operation mode when the amount is smaller than the predetermined amount. The measuring device 2 is controlled to execute. Note that the sample amount necessary for each measurement item is stored in the ROM 200e. For example, when the amount of the sample accommodated in the sample container 401 is less than the amount necessary for one measurement, the CPU 200a controls the measurement device 2 to execute the measurement in the first operation mode. In addition, even when a retest schedule is set for the sample stored in the sample container 401, if the amount of the stored sample does not satisfy the amount necessary for two measurements, the CPU 200a first The measurement apparatus 2 is controlled to execute measurement in the operation mode. In this way, even if the sample contained in the sample container 401 is a trace sample such as a pediatric sample or a sample that is insufficient and cannot be re-examined, the test can be performed quickly.
