It is characterized by:

[Embodiments of the invention]

FIG. 1 is a schematic block diagram showing one embodiment of the present invention.

As shown in FIG. 1, the automatic chemical analyzer in this embodiment has an input operation section 1, a storage section 2, a calculation section 3, and a display section 4.

The input operation unit 1 has an operation console that includes at least a sample number specification key for specifying the number of samples to be measured, a measurement item specification key for specifying a measurement item, an operation start key for starting a measurement operation, etc. However, when the operator presses the various keys K, necessary command signals are output to the arithmetic unit 6 and a control unit (not shown). The storage unit 2 stores measurement conditions according to the type of specimen and measurement items, such as the passage time of the specimen in a thermostatic chamber, the transportation time of the specimen from the reaction tube to the measurement cell, the photometry time in the measurement cell, etc. The operation section 6 has a memory for storing data and is configured to read out necessary data in response to a read command signal from the operation section 6 and output it to the operation section 6. By outputting a read command signal to the storage unit 2 in accordance with By adding up the measurement time! The measurement end time determined by Q'II and the elapsed time from the operation start key operation time are subtracted from the required measurement time to calculate the remaining measurement time and the like. The display unit 4 has a CRT monitor and a mode designation key for designating a display mode, and is configured to display the calculation results in the calculation unit on the CRT monitor in accordance with the mode designation keys. Note that the display unit 4 is not limited to the above-mentioned example, and may be a printer.

Next, the operation of the above configuration will be explained with reference to FIGS. 2 and 6.

Figure 2 is a flowchart for explaining the operation.
The figure is an explanatory diagram showing one display mode on the display section.

First, an operator sets various types of specimens and reagents in an automatic chemical analyzer. Next, by operating the input operation section 1 and pressing the sample number specification key, measurement item specification key, operation start key, etc., the input operation section 1 outputs a command signal necessary for the measurement operation to the control section. As shown in Fig. 1, the calculation unit 6 decodes the input command signal and stores in the storage unit 2 each measurement operation according to the measurement item and the type of specimen. It commands the reading of necessary time data such as the required time, such as the passage time of the specimen in the thermostatic chamber, the transportation time of the specimen from the reaction tube to the measurement hill, and the measurement time in the measurement cell. The arithmetic unit 6 collects the necessary time data and calculates a specific value of υ by adding them together.
Calculating the time required for measurement per sample In this way, the time required for measurement per sample is calculated for each type of sample subjected to measurement. Next, by adding up the measurement time required for each sample, the measurement time required to measure all the samples set in the automatic chemical analyzer is calculated. On the other hand, the automatic chemical analyzer is equipped with, for example, a digital watch. Digital data regarding the time when the operation start key on the input operation section 1 was pressed is output from the digital watch to the calculation section B. The calculation unit 3 calculates the measurement end time by adding the required measurement time to the time when the operation start key is pressed, that is, the measurement start time. When the current measurement is the last measurement of the day, the automatic cleaning time of the reaction tube is read from the storage unit 2, and the time obtained by adding the automatic cleaning time to the measurement end time is set as the final measurement end time. do. In addition, the calculation unit 3i
, J: The time elapsed from the time when the operation start key was pressed is counted, and the remaining time for measurement is calculated by subtracting the counted elapsed time from the required measurement time. From the calculation unit 6 to the display unit 4, the calculation results indicate the required measurement time, measurement end time, or final measurement end time.
Data indicating the remaining measurement time is output.

Next, when the operator presses the mode switch on the display unit 4, the measurement start time (,5TART TIME) and immediately after measurement end (END) are displayed on the CRT screen as shown in FIG.
TIME) will be displayed.

According to this embodiment described in detail above, when necessary data is input to the input operation section 1, the calculation section 3 automatically counts various times and times, and the results are displayed on the display section 4. can.

Although one embodiment of this invention has been described in detail above, this invention is not limited to the above embodiment, and it goes without saying that it can be implemented with appropriate modifications within the scope of the gist of this invention. Nor.

In the embodiments described above, the automatic chemical analyzer had a display section, but the present invention can also be applied to an automatic chemical analyzer that does not have a display section. In that case, a display device may be connected as a peripheral device to an automatic chemical analyzer without a display section.

Furthermore, the time in the arithmetic unit may be counted by counting pulses generated from a pulse source having a constant frequency.

〔Effect of the invention〕

According to this invention, the end time of the measurement of the sample set in the automatic chemical analyzer can be easily known from the display, so the operator can systematically prepare the next sample to be measured. can be done. In addition, knowing the measurement end time allows the operator to know the measurement start time of the next sample from his sister, so the operator is freed from the automatic chemical analyzer F4 and can perform other tasks until the measurement end time. can do. In particular, when performing sample preparation work as another work, since the next measurement start time is known,
The specimen can be prepared within the minimum necessary time, thereby preventing the deterioration of the specimen and making it possible to prepare a fresh specimen that can be measured with high precision. In this way, the end time of a measurement can be known at the start of the measurement, so preparations for the next measurement can be completed by the end time of the measurement, and the next measurement can be carried out immediately after the end of the measurement. In addition, it is possible to improve the operating efficiency of the automatic chemical analyzer and eliminate energy loss such as electric power due to idle state generation.
