Abstract

PROBLEM TO BE SOLVED: To efficiently select a function via a screen by limiting a plurality of functions to be executed in an analyzer from multiple built-in functions and displaying a function registration screen for setting their execution procedure. SOLUTION: Using a CRT 20 and an operation panel 23, a function is selected in the following way. Unnecessary functions are removed from all the function built in an automatic analyzer, and only the functions required by a user are registered in a memory unit 33. In addition to the limitedly set functions, the memory unit 33 stores an execution procedure for a combination of the plurality of functions. This registration content is listed on a support screen in the CRT 20, and selective registration by the user and a command for execution of the registered functions are carried out via the screen. Inputting operations for an analyzer can be carried out via the support screen of the CRT 20 alone, so that condition can be set efficiently. In this case, unnecessary functions are not displayed on the support screen of the CRT 20, so that erroneous operation can be prevented.

Description

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 a biological fluid sample, and more particularly, to an automatic analyzer capable of performing an instruction for measurement and setting measurement conditions through a screen.

[0002]

2. Description of the Related Art A large number of biological fluid samples are simultaneously treated in the analysis and analysis of a specimen for use in diagnosing a disease. For this reason, biological fluid samples such as blood and urine are often analyzed and measured using an automatic analyzer. The automatic analyzer performs an operation of adding a reagent and a sample to a reaction vessel on a reaction line to advance a reaction, and automatically obtaining a concentration of an analysis item of a sample by measuring a reactant.

In this type of automatic analyzer, the number of functions that can be executed is steadily increasing with the diversification of user needs. Since the setting and execution of each function are performed through the screen, the number of screens related thereto increases as the number of functions increases, and thus the number of built-in screens reaches, for example, 80 or more.

On the other hand, Japanese Patent Application Laid-Open No. H10-221129 is known as a prior art which deals with screen operations. This prior art considers the number of operation buttons displayed on a screen applied to an analyzer as a particle size distribution measuring device as a problem, and proposes a method for facilitating button operation. In other words, it describes that only a button necessary for the user is displayed from among a large number of operation buttons fixedly arranged in the left-right direction and the up-down direction on the monitor screen. This points out that the number of buttons is reduced, so that mistakes in pressing are reduced, and button operations are simplified.

[0005]

In a conventional automatic analyzer, one analyzer has many functions in order to meet the needs of many users. However, individual users rarely need all of the built-in functions, and once the mode of use of the analyzer is determined, the functions used by each user may be part of the built-in functions. Limited to only. However, in conventional automatic analyzers, all built-in functions are displayed on the screen,
The operator takes time to search for a desired screen,
The operation cannot proceed smoothly. In addition, there is a high possibility that an erroneous operation will occur due to a large number of built-in screens, and a delay in the work will be a problem.

[0006] The above-mentioned Japanese Patent Application Laid-Open No. 10-221129 merely teaches that the number of operation buttons in one screen is reduced, but does not mention handling of a large number of screens.

An object of the present invention is to provide an automatic analyzer capable of efficiently performing a function selection operation through a screen despite having a built-in screen corresponding to many functions.

The function to use. On the support screen, a list of the registered names of these selected functions is displayed in an index on a single screen, and functions as an instruction button through the screen. This support screen doesn't show any other features that weren't selected, so it ’s easier to navigate,
Erroneous operation is also prevented.

[0011]

FIG. 1 shows a schematic configuration of an automatic biochemical analyzer to which the present invention is applied. The analyzer of FIG. 1 includes a sample disk 2 serving as a sample moving device for moving a plurality of placed sample cups 1 one by one to a sample suction position, and a plurality of translucent reaction vessels 7. A reaction disk 8 arranged as a reaction line, a reagent disk 6a on which reagent bottles 25a for the first reagent are arranged, a reagent disk 6b on which reagent bottles 25b for the second reagent are arranged, and a reaction line Multi-wavelength photometer 11 for receiving a light beam 14 formed to pass through
And a stirring mechanism 9 for stirring the contents in the reaction vessel.
a, 9b, and a reaction vessel cleaning mechanism 10 attached along the reaction disk 8.

The sample dispensing mechanism 30 has a sample dispensing pipette nozzle 3 and a sample suction / discharge pump 4 connected to the nozzle. The reagent dispensing mechanisms 5a and 5b
It has pipette nozzles 24a and 24b for dispensing reagent solutions, and a pump 31 for sucking and discharging reagents connected to these nozzles. Operation control of each mechanism system and control of screen display are performed by the central processing unit 12 as a control unit.

The reaction disk 8 is controlled to repeat the operation of stopping the rotation of the reaction vessel row by half a rotation plus one reaction vessel every cycle. In this example, at the time of stoppage for each cycle, the reaction vessel 7 on the reaction disk 8 stops in a state where it has advanced counterclockwise. The multi-wavelength photometer 11 has a plurality of detectors at wavelength positions to be detected, and the light flux 1 from the light source lamp 13 when the reaction disk 8 is rotating.
Since a plurality of reaction vessels cross 4, light transmitted through the contents of the reaction vessels is detected.

A multiplexer 16 for selecting a wavelength according to an analysis item, a logarithmic conversion amplifier 17 and an A / D converter 18 for processing a signal corresponding to a measured wavelength, a printer 19, a CRT 20 as a screen display device, a reagent dispensing mechanism The drive circuit 21, the operation panel 23, and the like are connected via the interface 22 to the central processing unit 12 including a microcomputer.
It is connected to the. The central processing unit 12 also performs data processing such as calculation of the concentration of the analysis item of the measured sample or the enzyme activity value.

Next, the operation of analyzing a sample in the automatic analyzer of FIG. 1 will be described. When a start switch for starting an analysis operation on the operation panel 23 is pressed, the reaction vessel washing mechanism 10 starts washing the reaction vessel 7 and further measures a water blank. This water blank measurement serves as a reference for the absorbance subsequently measured in the reaction vessel 7. When the cleaned reaction vessel advances to the sample discharge position 15 by repeating the operation of the reaction disk 8 for one cycle, that is, the operation of moving the distance of the half rotation plus one reaction vessel and temporarily stopping, the sample cup 1 moves to the sampling position. I do.
At the same time, the corresponding reagent bottles 25a and 25b on the two reagent disks 6a and 6b also move to the reagent suction positions. Next, the sample dispensing mechanism 30 is operated, and the sample cup 1
Then, for example, the sample of the analysis item A is sucked by the sample pipette nozzle 3 and then a predetermined amount of the sample is supplied to the reaction vessel 7.
To be discharged. On the other hand, the reagent dispensing mechanism 5a starts operating, and the first reagent of the analysis item A bridged on the reagent disk 6a is sucked by the reagent pipette nozzle 24a.

Next, the pipette nozzle 24a moves to the corresponding reaction vessel 7 on the reaction disk 8, and after discharging a predetermined amount of the reagent held by suction, the pipette nozzle 24a is pipetted in a probe washing tank (not shown). The inner wall and the outer wall of the nozzle 24a are washed, and are prepared for the next reagent B of the analysis item B. After the addition of the first reagent, measurement by the multi-wavelength photometer is started.
The photometry is such that the reaction vessel 7 emits
It is done when you cross. When the reaction disk 8 rotates two rotations plus two reaction vessels after the first reagent is added, the stirring mechanism 9a operates to stir the sample and the reagent. When the reaction container 7 advances to the position 25 cycles after the sample discharge position 15, that is, to the second reagent dispensing position, the second reagent is added from the reagent pipette nozzle 24b, and then the mixture is stirred by the stirring mechanism 9b. The rotation of the reaction disk 8 causes the reaction vessel 7 to traverse the light beam 14 one after another, and the absorbance of each reaction solution is measured each time. A total of 50 photometric measurements are performed on these reaction solutions for a reaction time of 10 minutes. After the photometry, the reaction vessel 7 is used as the reaction vessel cleaning mechanism 1.
Washed from 0 to prepare for the measurement of the next sample. The measured absorbance is converted into a concentration or an enzyme activity value by the central processing unit 12, and the analysis result is output from the printer 19.

Next, a function selection operation using the CRT 20 and the operation panel 23 as a man-machine interface in the automatic analyzer of FIG. 1 will be described.

A storage section 33 is provided which can register only functions required by the user while excluding unnecessary functions from all functions built in the automatic analyzer. The storage unit 33 stores, in addition to a plurality of functions set in a restricted manner, an execution order when a plurality of functions are combined. Then, the registered contents are listed on the support screen. Instructions for selective registration and execution of registered functions by the user are performed through a screen. Since the input operation for operating the analyzer under desired conditions can be performed only on the support screen, the condition setting work at the start of the analysis operation can be efficiently performed. Unnecessary functions are not displayed on the support screen, so that erroneous operations can be prevented.

Examples of functions built into the automatic analyzer include setting of measurement conditions, setting of preparatory operations before the start of measurement, setting of a method for preparing a calibration curve and a method for confirming the result, registering analysis items, and measuring. Evaluation conditions for the results, setting of the cleaning time for each part of the analyzer, accuracy control of the equipment, replacement of parts, etc.
There are various types, and an operation screen corresponding to each function is built in.

The selective registration operation and the execution instruction operation when the automatic analyzer performs a plurality of functions continuously are described below.
This will be described with reference to FIGS. FIG. 2 is a flowchart of the function registration operation, and FIG. 3 is a flowchart for executing a function registered in a limited manner. FIG. 4 is a diagram for explaining an example of a function to be registered with restriction, and FIG. 5 is a diagram for explaining an operation example at the time of execution.

When a plurality of functions are to be executed continuously, such as performing a photometer check after deleting the data of the previous day, the registration operation is performed in advance in the following procedure. First, in S1 of FIG. 2, a screen for function registration is displayed on the CRT 20 according to an instruction from the operation panel 23. This function registration screen has an input field having a vertical axis and a horizontal axis as shown in FIG. 4, for example. However, the number that can be registered can be increased as needed by the user.

In S2, "1" is entered in the registration number field on the screen, and in S3, a registration name for expressing a combination of functions to be executed first is registered, for example, under the name of "routine preparation". . Then, "2" is entered in the column of the number of functions (or the number of screens), and "1" is entered in the column of the execution order.
Next, in S4, a job list is displayed on the CRT, and in S5
Then, when "routine job" is selected from the job list for the function to be used first, the routine job is registered in the input field of the job menu on the registration screen.

At S6, a screen list is displayed on the CRT 20, and "data review" is selected from the list (S7).
Then, the data review is registered in the input field of the submenu of the registration screen. In the next S8, the window list is displayed on the CRT.
20 and select "DATA DELETION" from the list (S9), data deletion is registered in the input field of the window. Further, in S10, a function list is displayed on the CRT 20, and "all" in the list is selected (S11), and all are registered in the function input field. By these operations, a registration number, a registration name, and the like are stored in the storage unit 33 (S12).

Next, in step S13, the apparatus determines whether or not to register the function further or instructs the user. In this example, since the number of functions is 2, the process returns to the step S2 to start the work of registering the second function to be used in the combination of a plurality of functions. That is, the registration number 1 on the registration screen
"2" is input in the execution order corresponding to. Then, a job list is displayed on the CRT in S4, and the “utility job” selected in S5 is registered in the job menu. The screen list is displayed in S6, and the selected “maintenance” is registered in the submenu input field in S7. The window list is displayed in S8, and the selected “operation check” is registered in the window input field in S9. Further, a function list is displayed in S10, and the selected "photometer check" is registered in the function input field in S11. This means that the registration of the continuation of a plurality of functions corresponding to the registration number “1” has been performed by the storage in S12.

In the example of FIG. 4, another continuous combination of a plurality of functions is registered. In this case, the process proceeds to S2 after S13, "2" is entered in the registration number input field of the registration screen of FIG. 4, and in S3, "Weekend washing" is entered as the name for registration in the registration name input field, Hereinafter, steps S4 to S12 are registered in the same manner as in the case described above. As a result, two types of combination functions are registered. However, when a combination of a plurality of functions or a single function is registered in advance, steps S2 to S12 are repeated after S13.

When the user has registered all the functions to be registered in advance in the automatic analyzer for use, the process advances from S13 to S14 to check the registered functions, for example, as shown in FIG. Is displayed. Thereafter, the operator gives an instruction to end the registration work from the operation panel 23 (S15). In this way, from among a large number of functions built in the automatic analyzer, the restriction setting of a plurality of functions required by the user is made, and the execution order when a plurality of functions are combined is registered through the screen.

Next, a procedure for executing a plurality of functions registered as described above will be described. S21 in FIG.
Then, the support screen is displayed on the CRT 20. On the support screen, all the functions registered and set as described above are listed in one screen. In this list, at least a registration number and a registration name are displayed (S22). S23
When a registration number on the support screen is selected, the corresponding registration function is searched in S24, and the registration function is displayed in S25. For example, when the registration number “1” is selected, a data review screen relating to “data deletion”, which is the first function to be performed relating to the routine preparation, opens.

Then, when an instruction is given to execute the function in S26, data deletion is executed (S27). The data review screen is, for example, as shown in FIG. 5, and the item (name) of “data deletion” registered in advance is different from other items (names) in character size or display color (color).
Is represented by Thereby, the operator can immediately recognize the function to be selected, and can surely select the target function.

In S28, it is determined whether or not there is another continuous registration function. In the case of the example of FIG. 4, since it is set to perform a photometer check after data deletion,
The process returns from S28 to S25, and the maintenance screen of “photometer check” is automatically opened in S26. Then, the operator can instruct whether execution is necessary through the maintenance screen. After instructing execution of the desired function, the operator instructs termination (S29).

As described above, by selecting one registration number, it is possible to continuously specify a plurality of continuous functions, for example, data deletion and execution of photometer check.

In the above embodiment, the execution order of the functions can be rearranged by changing the registration number in FIG. Immediately after the input steps such as S5, S7, S9 in FIG. 2, each input information may be stored for registration.

In the automatic analyzer to which the screen operation simplification system as described above is applied, by pre-registering the screen operation procedure of the function necessary for the user, the screen search when using the function becomes unnecessary. . Therefore, if there is a minimum knowledge of the automatic biochemical analyzer, it is possible to utilize necessary functions without erroneous operation, and to improve work efficiency and prevent erroneous operation.

[0033]

According to the present invention, even if the automatic analyzer has a built-in screen corresponding to a number of functions, it is not necessary to display a screen unnecessary for the user, so that the function selecting operation through the screen can be efficiently performed. Can be done
