Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic analyzer, and more particularly to an automatic analyzer suitable for increasing the efficiency of requesting and registering items to be analyzed.

[0002]

2. Description of the Related Art In a general automatic analyzer, an operation screen for requesting an item to be analyzed is constructed for a dedicated operator. That is, set items can be registered together on the setting screen for requesting individual items. Therefore, there is a problem that the screen is complicated and the usability is poor. For example, on the screen for requesting and setting individual items, there are many items that require you to enter various information such as the position to set the sample on the sample disk, the type of sample, patient ID, and the presence or absence of re-examination. Also, it is not uncommon for parameter errors to occur due to incorrect input.

Further, when registering an item corresponding to the position of the sample disk, that is, an item corresponding to a sample, a screen for requesting an urgent sample item and a screen for requesting a general item are separated from each other and have a mutual relationship. Absent. Therefore, if you try to change the requested item in the urgent sample item, press the item change key, change the screen, and change the item, you automatically return to the original screen after changing the item and do not fully understand the screen configuration. There is a problem that I can not master it.

There are also automatic analyzers in which the position of the sample disk for requesting an urgent sample is only one. With such a device, the next urgent sample can be requested until the analysis of the urgent sample is completed. First, you have to wait for the analysis request.

Further, in some devices, a keyboard is prepared in addition to the touch panel keys, and operations such as input from the keyboard and input from the touch panel keys are complicated, and there is a big problem in terms of usability.

When various screens are complicatedly related to each other or input from a keyboard or a touch panel key, it is not possible to meet the demand for easy and quick use by anyone in case of night emergency, etc. Has the problem that it cannot be used.

1 shows the concept of an automatic analyzer according to an embodiment of the present invention. A rotating reaction table 5 holds a translucent prismatic plastic reaction container 6. Reference numeral 2 is a rotating reagent table in which a reagent container 3 is held. A rotating sample table 10 holds a sample container 11 therein.

When the sample container 11 of the sample table 10 is moved to the sample suction position, the sample therein is sucked into the nozzle held by the sample movable arm by the sampling mechanism 8 and the microsyringe mechanism 15, and the sample is collected. It is dispensed into the reaction container 6 of the reaction table 5 which has moved to the pouring position.
Reagent pipetting mechanism 4 and microsyringe mechanism 17
Is the reagent container 3 of the reagent table 2 that has moved to the reagent suction position
It operates so as to suck the reagent into the reagent nozzle held by the movable arm from the inside, and dispenses the sucked reagent into the reaction container 6 of the reaction table 5 which has moved to the reagent dispensing position. Works.

A stirring mechanism 9 is used for stirring the liquid in the reaction container 6 at the reagent dispensing position. A high-speed multi-wavelength photometer 13 measures the reaction liquid in the reaction vessel 6 which crosses the optical axis by the rotation of the reaction table 5 at a predetermined wavelength. 12 and 16 are a cleaning nozzle mechanism and a cleaning water supply / drainage pump mechanism, respectively.
Used to wash.

Besides, a LOG converter 18 for logarithmically converting the signal obtained by the measurement into an absorbance, an A / D converter 19 for A / D converting the signal, a computer for operation control of each part and data processing. 1, output printer 21, L with touch panel for requesting and registering items to be analyzed
A CD (liquid crystal display) 20, a floppy disk mechanism 22 for programs, measurement conditions and data memory, a circulating constant temperature water tank 14 for keeping each reaction container on the reaction table 5 at a constant temperature, a microcomputer 1 and various parts are connected. The interface 24 and the like are provided.

The reaction table 5 repeats the operation of rotating for one rotation + one pitch (for one reaction container) and then stopping, and rotating and then stopping. Therefore, one reaction container 6 is moved to the sample dispensing position for each repetition. On the other hand, each time the reaction table 5 is repeatedly rotated, the sample table 10 rotates by one sample and the sample container 11 moves to the sample suction position. The sample in the sample container 11 thus successively moved to the sample suction position is sucked by the sampling mechanism 8 and the microsyringe mechanism 15 and sequentially dispensed to the reaction container 6 sequentially moved to the sample dispensing position. .

Between the stoppage of the reaction table 5 for dispensing the sample to the reaction container 6, the sample suspension is stopped halfway. At this midway stop and / or when the reaction table 5 for sample dispensing is stopped, the reagent in the reagent container 3 at the reagent suction position is sucked by the reagent pipetting mechanism 4 and the microsyringe mechanism 7, The sample is dispensed into the reaction container 6 at the dispensing position and the sample is dispensed. What kind of reagent should be dispensed to the sample dispensed in which reaction container is predetermined,
Therefore, the reagent table 2 must meet the rule.
Behavior is controlled.

At the reagent dispensing position, stirring is performed by the stirring mechanism 9 in order to further mix and react the dispensed sample and reagent. The reacted reaction liquid is measured when it crosses the optical axis of the high-speed multi-wavelength photometer 13. The reaction container containing the reaction liquid after the measurement is washed by the washing nozzle mechanism 12 and the washing water supply / drainage pump mechanism 16 at the washing position.

FIG. 2 shows a display example of the item request image displayed on the image display surface of the LCD with a touch panel. When the power is turned on, first, the navigation screen (first screen) shown in (A) is automatically displayed. Requesting and registering a set item to be analyzed on this screen (from this point, the first screen is the set item request screen), and pressing the start key starts the analysis. If you want to add a set item that is not on the navigation screen for analysis,
The set item request screen (second screen) shown in (B) is displayed, the additional set item is requested and registered on this screen, and the start key is pressed to start the analysis. When you request and register each test item and want to analyze it, the test item request screen (3rd screen) shown in (C)
Is displayed, request and register the necessary test items on this screen, and press the Start key to start the analysis.

That is, when it is desired to analyze only test items registered as set items in advance, item request and registration are performed on the first screen, and when the set items on the first screen are not sufficient, the second screen is sufficient. If you want to request and register a set item that is not present, and if you want to request and register individual test items one by one, make the request and registration on the 3rd screen, respectively. You can select and use the required screens according to your level.

The first screen, that is, the navigation screen is designed to have only the minimum necessary functions. That is, as shown in FIG. 2A, the navigation screen is composed of four keys and one message column. The message field is located at the top of the screen and the keys are located at the center and bottom of the screen. In the example of this screen, a message column 51 for instructing the sample position of the sample table 10 in which the sample should be set, an item registration key 52, and an item change for changing the item, which are necessary for identification between samples There are a key 53, a start key 54 for starting analysis, and a stop key 55 for stopping analysis. A square button shape represents a touch key, and when pressed, it is highlighted in white, indicating that an input has been made.

A set item is, for example, a liver function,
Multiple test items (GO) to be analyzed, such as renal function, cardiac function, lipids, electrolytes, etc.
T, LDH, ALD, TP, LAP, TTT, GPT,
F-CHO, ALP, CHE, etc.). For example,
In the example of FIG. 3 (A) in which the vertical axis represents set items and the horizontal axis represents test item numbers, four set items of liver function, renal function, set item (A) and set item (B) are set. There are test items to be analyzed, each of which is indicated by a "0" mark. “X” marks are test items that do not need to be analyzed. The pattern shown in FIG. 3A is registered (stored) in the memory of the computer 1.

The first screen of FIG. 2A is shown in FIG.
This is an example in which a single set item called liver function shown in (A), which is the same as the uppermost pattern, can be requested and registered. This is achieved by pressing the item registration key 52. . That is, by pressing the item registration key 52,
The test item indicated by the "0" mark in the set item of liver function in (B) is automatically requested and registered. Therefore, when the user or the operator requests a test item registered as a set item called liver function at night, for example, and analyzes it, according to the screen display of the message column 51, the sample desired to be measured is displayed as a message. When the item is set at the sample position indicated by J and the item registration key 52 is pressed, the test item registered as a set item called liver function is automatically requested and registered. When this registration is completed, the sample position number 5 in the message field 51
6 is incremented by “1”, and the sample with the incremented sample position number is ready for the same request and registration.

After that, by repeating the same operation for the number of samples desired to be measured, the request and registration for all the samples of the test items registered as a single set item called liver function are completed. Therefore, by simply pressing the start key 54, the analysis of the registered test items is started.

Instead of setting one sample each time the sample position number in the message column 51 is incremented, the samples are collectively set in advance in the sample table 10 starting from the sample position number designated by the message. Then, the test item can be requested and registered by simply pressing the item registration key 52 by the number of samples. Therefore, it can be said that the request and registration of the items to be analyzed on the first screen are suitable for beginners.

When the start key 54 is pressed, a parameter check is also performed. If there is no abnormality in the parameters, the start key 54 is highlighted in white to indicate that the start key 54 has been accepted, and analysis is started. On the contrary, when the parameter error occurs, the message of the parameter abnormality is displayed in the message column 51.

Even if the user wants to request and register an additional sample during the analysis (the start key 54 is highlighted in white), the additional sample is set at the sample position indicated by the message and the item registration key 52 is used for the additional sample. If you press only a few minutes, you can automatically request and register additional samples for analysis.

When the number of additional items exceeds the number of samples that can be registered, a message "cannot be added" is displayed in the message column 51, and anyone can understand.

It may be desired to stop the analysis during the analysis. This is accomplished by pressing stop key 55.

The analysis start and stop are the first.
This is possible not only on the screen but also on the second and third screens.

When it is desired to change the set item and / or the test item, the item change key 53 is pressed. As a result, the second screen of FIG. 2 (B) is automatically displayed instead of the first screen of FIG. 2 (A). At this time, the value of the sample position number 56 displayed on the second screen matches the value of the sample number 56 displayed on the first screen immediately before the item change key 53 is pressed to change the item on the first screen. ing.

On the second screen, an additional set item consisting of a plurality of test items other than the test items requested and registered on the first screen, or the additional set item and the request and registration on the first screen are registered. It is possible to request the set items to be registered, and to request and register the sample required to be registered. That is, on the second screen, set items that cannot be requested and registered on the first screen can be requested and registered.

On the second screen, six set item keys 57
And an item key 68 for changing the test item, a registration key 58, a start key 54 necessary for starting the analysis, a stop key 55 for stopping the device, an alarm monitor key 59 for checking the device status, and a return to the navigation screen. Key 60, menu key 6 for transitioning to another menu
5, there is a column in which the sample position number 56 of the sample table is displayed. A menu key 65 is a menu display key for selecting, for example, calibration, parameter changes, and device maintenance (this is the same for the third screen described later).

As the set item key 57, in addition to the keys for the set items of liver function and renal function, set item A,
Keys for B, C and D are shown, but those keys
Among the set items that can be requested and registered in 1., the set items of liver function and renal function and the test items assigned to the set items A and B are shown in FIG. 3C. That is, each of these set items is composed of test items indicated by a "0" mark in FIG.

The desired key in the set item key 57,
For example, when the renal function key is pressed, the test item indicated by "0" in the set item column of renal function of FIG. 3C is requested for the sample of the displayed sample position number, and the request is made. The test item is registered by pressing the registration key 58. Once this registration is made,
The displayed sample position number 56 is incremented by "1", and it is possible to similarly request and register the desired item for the sample of the incremented sample position number.

Thus, by repeating the operation of pressing the desired key in the set item key 7 and the operation of pressing the registration key 58, the sample of the sample position number which is incremented by "1" each time. You can set and register desired set items one after another.

It should be noted that a plurality of keys such as the liver function key and the kidney function key in the set item key 57 may be pressed for one sample. In this case, a plurality of set items are requested and registered for one sample.

When the registration is completed, the analysis can be started by pressing the start key 54. of course,
By pressing the stop key 55 during the analysis, the analysis can be stopped. Further, the state of the device can be monitored by pressing the alarm monitor key 59 (this is the same in the case of the third screen described later).

Since the procedure for requesting and registering the items on the second screen is a little more complicated than that on the first screen, it can be said that the level is suitable for intermediate users. Of course, when it is troublesome to request and register an item using the second screen, it is possible to return to the first screen display at any time by pressing the return key 60. In this case, the value of the sample position number 56 displayed on the first screen matches the value of the sample position number displayed on the second screen immediately before pressing the return key 60.

Request and register test items individually,
If you wish to change it, press item key 68 on the 2nd screen. As a result, the display screen changes from the second screen to the third screen shown in FIG.

On the third screen, a position key 61, a test item key 62, and a star key for confirming the test items registered for the sample at each sample position.
There are a to-key 54, a registration key 58, a stop key 55, a menu key 65, a return key 60, and item display switching keys 63 and 64. Since there are many test items and it is difficult to display them all at once, they are classified into several groups, selected and displayed on a group-by-group basis. The selection display of the group of test items is performed by the item display switching keys 63 and 64. That is, the selection display in the forward direction of the test item group is keyed.
It is carried out by pressing 63, and the selection display in the backward direction is carried out by pressing the key 64.

When the 3rd screen is displayed, the value of the sample set position number 56 that first appears on that screen is the value of the sample position number displayed on the 2nd screen immediately before the item key 68 on the 2nd screen is pressed. Matches

When one or more desired keys of the test item keys 62 are pressed, the test item corresponding to the key is requested for the sample of the displayed sample number, and the registered key is pressed. You can register by pressing 58. When the registration is performed, the sample position number 56 is incremented, and the test item request and the registration preparation for the sample of the incremented sample number are completed. Therefore, by repeating the same operation, it is possible to request and register the test items one after another for the sample having the sample position number that changes each time.

After the registration is completed, the start key 54 is pressed to start the analysis, and the stop key 55 is pressed to stop the analysis. Also, return key-6
If 0 is pressed, the display screen returns from the 3rd screen to the 2nd screen. At that time, the value of the sample position number 56 displayed on the second screen matches the value displayed on the third screen immediately before pressing the return key 60 on the third screen.

Confirmation and change (cancellation, correction, addition, etc.) of registered test items can be performed for each sample by pressing the position key 61. That is, position key-6
When 1 is pressed, the value of the displayed sample position number 56 returns to the very first value “1”. After that, each time the position key 61 is pressed, the value of the sample position number 56 is incremented by "1".

Whether the test item is registered for the sample of the displayed sample number is determined by the test item key.
This can be confirmed by checking whether the corresponding key of 62 is highlighted in white. That is, the key of the registered test item is highlighted in white and the key of the unregistered test item is not highlighted.

The contents stored in the memory of the computer 1 which is performing this confirmation are as shown in FIG. 3 (D). The figure shows a table of test items for each sample position number, that is, for each sample. “0” marks indicate registered test items, and “x” marks indicate unregistered items. As is clear, confirmation of the test item for each sample by pressing the position key 61 means confirmation of the contents of FIG. 3 (D).

Since the registered contents of the test item for each sample can be confirmed as described above, the test item can be changed for each sample as needed based on the confirmation.
This change is possible by using the test item key 62 and the registration key 58. That is, when you want to delete the registered test item, the test item key 62
Of these, it can be canceled by reversing and pressing the white-painted key again. On the contrary, if the user wants to add the test item, he / she can request the addition by pressing a key which is not painted white in the test item key 62.
When the item to be requested is decided, if the registration key 58 is pressed at that time, the item is stored (registered) in the memory.

Of course, when the number of requested test items is larger than the number displayed on one screen or when a test item on a hidden screen is requested, the desired test item is selected by pressing the key 63 or 64. It can be dealt with by displaying a certain screen.

FIG. 4 shows a procedure flow for requesting and registering items to be analyzed. Referring to the figure, when the power is turned on, first, a navigation screen (first screen) (see FIG. 2A) is automatically displayed. If the user or the operator wants to request and register the test items registered for the set item of liver function, the liver function set registration key 52 is pressed. This procedure is repeated until all samples are completed. When the procedure is completed, pressing the start key 54 will start the analysis.

On the other hand, when the request and registration of the set item of liver function is not performed, the item change key 53 on the first screen is pressed to display the second screen (see FIG. 2B) instead. If neither the change of the test item nor the change of the set item is necessary, the flow returns to the display of the first screen, but if there is the change of the set item, the key 57 is operated to make the change.

To change the test item, press the item key 68 on the second screen to display the third screen (see FIG. 2C) instead, and operate the key 62 to change the test item. Then, the newly requested test items are registered by the registration key 58.

After that, if the test item registration status for each sample position is to be confirmed, the position key 61
Confirm the request item (test item) by, and if you want to change the test item further, change and register it by operating the key 62 and the registration key 58.

When the set items are changed and registered on the second screen, and the test item registration status for each sample position is not confirmed on the third screen, the flow is displayed as "Complete registration for all samples? Return to the step. In addition, when confirming the test item registration status for each sample position on the 3rd screen, even if the test item is not changed, the change,
Even when the registration is performed, the flow similarly returns to the step "Registration completed for all samples?" In FIG.

From the above description, it is understood that even if there is a difference in operator level, it is possible to efficiently request and register the items to be analyzed. In addition, since it is possible to easily confirm and change the registered contents and register the changed items by using the test item screen, as a result, it is possible to prevent the registration error of the items to be analyzed. .
Further, since the first screen, the second screen and the third screen are selectively displayed on the same screen display surface, the screen display is consequently simplified, so that the request for the item to be analyzed is made. And the chances of registration errors being reduced.
