DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic analyzer for analyzing components in a biological sample, and more particularly to an automatic analyzer having a function for simplifying and ensuring the operation of the automatic analyzer. It is.

[0002]

2. Description of the Related Art In recent years, the number of clinical chemistry test items in an automatic analyzer has increased, and diagnosis and treatment based on the data have become difficult.
It has been running for four hours. Automatic analyzers have also become multifunctional, and their use is performed by trained and specialized operators. However, in the absence of specialized operators such as nighttime and holidays, when an urgent examination is required, an operator unfamiliar with the device, such as a doctor or a nurse, operates the device.

[0003] The operation procedure of a conventional automatic analyzer is as follows.
It is as follows. The operator inputs a request for a patient sample from the screen, places the sample at the position of the sample container arrangement unit, and starts analysis.

[0004]

In the conventional automatic analyzer, it is necessary for the operator to determine which screen should be used for requesting a patient sample and at which position the sample should be set. Since it was not presented, in the input operation of the information on the sample at the time of the sample measurement request (measurement items, the position of the installed sample container arrangement part, etc.), the user may input the position where the sample is already installed, Even if the already installed sample is an unmeasured sample or a sample awaiting re-measurement, it is incorrectly excluded,
There is a problem that an error such as installation of another new sample is likely to occur.

[0005] It is an object of the present invention to provide an automatic analyzer that is less likely to be erroneously installed when a patient sample is installed.

[0006]

The automatic analyzer is roughly divided into an analyzer and an operation unit.

According to the present invention, the operation section has an area for storing information for each position on the sample container array section, such as a sample measured by the analysis section or unmeasured, and performs processing for each position of the sample container array section. , Unprocessed information, the operation unit determines whether the position is an installable position according to the information, and automatically displays only the installable position on the screen.

The information for each position is, for example, "1. measured" for each position of the sample arrangement section of the analysis section.
The information of the installed sample such as “2. Request item is registered but not measured”, “3. Under measurement”, “4. Waiting for re-measurement”, “5.

[0009]

The function of the above technical means is as follows.

[0010] The cause of erroneously removing an unmeasured sample or a sample awaiting re-measurement in the sample container array portion or inputting an unusable sample setting position is caused by a sample available at the time of a measurement request. Because the installation position was not provided from the device side,
“1. Measured”, “2. Request item is registered but not measured”, “3. Measuring”, “4.
It has an area for storing position information such as “5. End of result output”. By storing the above information, it is determined whether the position can be installed in the apparatus. By displaying the image on the screen, the erroneous operation can be prevented and the operation method can be simplified.

[0011] In the initial state of the screen display, and the analyzable Position emissions are displayed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to FIGS.

FIG. 1 is a schematic diagram showing one embodiment of an automatic analyzer to which the present invention is applied, FIG. 2 is a diagram showing an example of a process for displaying a position where a sample can be placed in a sample container arrangement section,
FIG. 3 is a configuration diagram of information belonging to each sample installation position in FIG. 2, and FIG. 4 is an example of a screen displaying the sample installation possible positions in FIG.

An automatic analyzer according to one embodiment of the present invention will be described.

In FIG. 1, a sample container 1 containing a sample is shown.
Are installed on the sample disk 2. The sample disk 2 is controlled by a computer 3 via an interface 4.

The sample disk 2 is rotated and moved below the dispensing probe of the sample mechanism 5 in accordance with the order of the samples to be analyzed, and the sample of the predetermined sample container 1 is connected to the sample dispensing mechanism 5. A predetermined amount is dispensed into the corresponding reaction vessel 6 in the reaction vessel row by the sample pump 7.

The reaction container 6 into which the sample has been dispensed is placed in a reaction tank 9.
To the first reagent addition position. A predetermined amount of the reagent sucked from the reagent container 12 by the reagent pump 11 connected to the reagent dispensing probe 8 is added to the moved reaction container 6.

After the addition of the first reagent, the reaction vessel 6 moves to the position of the stirring mechanism 13 and the first stirring is performed.

Such addition and stirring of the reagents is performed for the first to fourth reagents.

The reaction vessel 6 in which the contents are stirred passes through the light beam emitted from the light source, and the absorbance at this time is detected by the multi-wavelength photometer 15. The detected absorbance signal is A
The data enters the computer 3 via the interface 4 via the / D converter 16 and is converted into the concentration of the sample.

The density-converted data is printed out from the printer 23 via the interface 4 and displayed on the screen display unit 21. Reference numeral 24 denotes a floppy disk.

After the photometry, the reaction vessel 6 is moved to the position of the washing mechanism 19, discharged from the inside by the vessel washing pump 20, washed with water, and subjected to the next analysis.

An analysis item and an analysis condition can be input for each sample on the screen 21 or the keyboard 22.

Next, a process for displaying the sample installation position of the sample container array will be described.

In FIG. 2, the computer of the operation unit is
It has a position information storage unit and an installation possibility determination unit. When it is confirmed that the sample installation position of the sample container arrangement unit is in the installation possible state, the corresponding position number is displayed on the screen of the screen display unit 21 of the operation unit. Encourage the installation of analysis samples.
When the registration of the sample is completed, the above operation is repeated for the next position. If the position information is in a state where installation is impossible, the corresponding position number is skipped and the information of the next position is confirmed.

Next, the information on the sample installation position of the sample container arrangement section includes a position number 31, a position state 3
2, the setting flag 33 is provided. The position number 31 is a sample installation position number of the sample container arrangement section. The state 32 of each position is a state such as "no sample", "position registered", "measuring", "waiting for re-measurement", "measurement end", and the like. The installable flag 33 is
If the above-mentioned position is in a state where it can be used for new measurement such as "no sample" or "result output completed", it will be "ON". It becomes "OFF". The position information is sent to the computer 3, and the apparatus determines whether the position is ready for installation.

Next, a screen for displaying a sample installation position will be described.

In FIG. 4, the sample setting position determined to be possible to set the sample by the processing shown in FIG. 2 is displayed in the sample setting position display area 41.
The operator can set the sample at the position displayed in the sample setting position display area 41 and start the analysis. In the initial state at the time of transition to the above screen, the position of the sample array portion that can be analyzed is displayed.

In the automatic analyzer to which the present invention is applied, since the displayed sample installation position is always the installable position, it is necessary for the operator to confirm, for example, whether the sample is an unmeasured sample or a sample waiting for re-measurement. A new sample can be set in the sample arrangement section without having to make any changes. Even if a sample is placed at that position, the sample is in the “measurement completed” state, so the sample is removed and the corresponding position can be used for registration of a new sample.

[0030]

According to the present invention, the information on the position of the sample container installation section is stored, the available position is determined based on the information, and only the available position is automatically determined when a sample measurement is requested. Since it has a screen display function, it is possible to provide an automatic analyzer that is easy to operate and has less erroneous operations.
