Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, when inputting and setting a measurement item for performing biochemical analysis for each sample, provides an operator with information useful for finding an error in the setting and information such as reagent usage amount. The present invention relates to an automatic chemical analyzer equipped with an input setting device capable of transmitting information to a user.

[0002]

2. Description of the Related Art Generally, the measurement items to be biochemically analyzed differ depending on the pathological condition of a patient, and the increase in the number of samples in recent years has complicated the inspection work. In order to cope with this, development and improvement of automatic chemical analyzers capable of high-speed multi-item processing have been actively carried out.

An automatic chemical analyzer is designed to perform chemical analysis by sampling and dispensing a sample and a reagent into a reaction tube based on measurement items set by an operation panel, stirring and mixing, and then measuring a reaction process in the reaction tube. It is a device to perform.

Conventionally, when setting and registering a measurement item to be analyzed in the storage section of such an apparatus, the operation is performed while visually confirming whether or not the setting has already been made by referring to the setting mode screen displayed on the display. Input work is done using the panel. At this time, the measurement items include special items that are rarely used and items that are used all the time.Therefore, the operator predicts the amount of each reagent required before performing chemical analysis work, and replenishes the necessary reagents. We are preparing.

On the other hand, when the frequency of use of each measurement item is unclear, special items and other items are distinguished in advance, and the remaining amount of the reagent is constantly checked to supplement and store a fixed amount of the reagent. There is.

[0006]

However, when the number of samples is large, the burden on the operator who carries out the work of inputting and setting the measurement items is large, and the number of input errors is inevitably large. As a measure for preventing such an input error, once the contents of the setting items for each sample are output to a display or a printer, operations such as checking them again are performed. Since this reconfirmation is a laborious task, it is difficult to completely correct an input error in a short time.

Further, in the conventional device, the remaining amount of the reagent can be confirmed, but the amount of the reagent used for the analysis to be performed cannot be confirmed, so that the preparation of an extra reagent or the confirmation of the amount of the reagent to be replenished is delayed, There is a problem in that the chemical analysis work is temporarily interrupted due to the replenishment of reagents, and the efficiency of the analysis work is deteriorated.

The present invention has been made in order to solve these problems, and an object thereof is to provide an automatic chemical analyzer which can help detect an input setting error and improve the work efficiency of chemical analysis. ..

[0009]

An automatic chemical analyzer according to the present invention is provided with an input setting device for performing input setting of measurement items for each sample with reference to an input setting mode screen displayed on a display section.

A total number calculation unit that calculates the preset total number for each and outputs the preset total number information to the writing unit, and the setting item presence / absence information and the preset total number information of the measurement item from the storage unit by the input setting mode signal from the input unit And a display means for simultaneously displaying on the display unit the presence or absence of the setting of the measurement item in each sample and the preset total number of each measurement item based on these information. To.

As the input setting device, a writing means for writing the setting item presence / absence information of each sample and various input information to the storage unit, and the setting item presence / absence information of each sample is read from the storage unit. Based on this information, the total number calculation means for calculating the preset total number for each measurement item and outputting the preset total number information to the writing means, and the setting presence / absence information of the measurement item from the storage part by the input setting mode signal from the input part And the total number of preset items is read out, and based on these information signals, the presence / absence of the setting of the measurement item in each sample and the preset total number of each measurement item are displayed simultaneously on the display unit. It is also possible to provide a display means for displaying the set measurement item and the other measurement item in a distinguishable manner. .

Further, in order to display the reagent amount used before the analysis work, the reagent amount information and the preset total number information necessary for each measurement item already stored are read out from the storage unit, and the reagent is used based on these information. A calculation unit that calculates the amount and outputs the reagent usage amount information to the writing unit, and a reagent usage amount information is read from the storage unit in response to the reagent usage amount display mode signal from the input unit, and the reagent name is based on this information. It is advisable to provide a reagent usage amount display means for displaying a list of reagent amounts used for each of them on the display unit.

[0012]

In the automatic chemical analyzer according to the present invention, when the measurement items for each sample are input and set, the preset total number is displayed on the input setting mode screen. Therefore, if the total number of each measurement item is obtained from the measurement item information list for each sample such as the work list in which the input information is described, and by comparing this with the preset total number displayed on the display unit, the setting error will be Easy to find. Further, since the unset items and all the set items that cause a relatively large number of input mistakes and other items are displayed in a distinguishable manner, it is possible to easily recheck the input mistakes even when a large number of measurement items are set. .. Further, since the reagent usage amount display means allows the amount of the reagent liquid required before the analysis to be known, the necessary reagents can be replenished without interrupting the analysis work, and these preparations can be completed completely. ..

The control unit 3 is composed of a microprocessor and the like, processes necessary information based on a preset program, and
The display unit 4 and the like can be controlled by receiving a command signal from the input unit 2. Then, the display unit 4 can display the processing numerical value and the like on the mode screen specified by the control unit 3. Next, a procedure for operating the input setting device when setting and registering measurement items in the storage unit 1 of the automatic chemical analyzer with reference to the worksheet 5 will be described.

Here, as shown in FIG. 5, the worksheet 5 is composed of a list in which samples are vertically arranged and measurement items are arranged horizontally, and a total number column showing the set total number is provided for each measurement item. , Worksheet 5 has items to be measured
The mark indicates the item that does not require measurement, and the x mark is indicated.

First, in order to input and set the measurement item for each sample, the input setting mode is selected by the key operation of the input unit 2, and the input setting mode signal is sent to the display means 31. The display means 31 calls the input setting mode screen signal stored in advance from the storage unit 1 and displays the input setting mode screen on the display unit 4 based on this signal. In this input setting mode screen, as shown in FIGS. 2 and 3, the sample number 6 is displayed at the left end of the screen, and each measurement item name 7 (A, B, C, D,
E) The preset total number is displayed in [] on the left side of E), and the * mark 9 for identifying a specific item is displayed between the preset total number 8 and the measurement item name 7, and each measurement item name is displayed. A mark 10 indicating whether or not the setting is registered (o with setting, x without setting) is displayed on the right side of 7.

When the setting presence / absence information of the measurement item in each sample is input by the key operation of the input unit 2, the setting presence / absence information is stored in the storage unit 1 via the writing means 32. The setting item presence / absence information of the measurement items in each sample stored in the storage unit 1 is read by the total number calculation means 33, and based on the information, the preset total number information indicating the total number set for each measurement item is calculated. To be done. And the preset total number information is
It is stored in the storage unit 1 via the writing means 32.

Next, the measurement item setting presence / absence information and the preset total number information are read from the storage unit 1 by the display means 31, and based on these information, the presence / absence of the measurement item setting in each sample on the input setting mode screen ( o, x) and the total number of items that have already been set for each measurement item (indicated by a numerical value in []) are displayed, and the * mark indicates the measurement items that have already been set and the measurement items that have not been set. Is marked.

In this embodiment, all the set and unset items are marked with * to make them identifiable. However, the present invention is not limited to this, and the item name 7 is colored by an appropriate color for identification. You may allow it.

In the above embodiment, since the preset total number is displayed on the input setting mode screen, if the preset total number is compared with the total number shown on the worksheet 5, it is possible to detect an input error with a high probability. You can Next, the operation for displaying the reagent usage amount will be specifically described.

The storage unit 1 stores in advance reagent amount information such as a reagent amount required for one analysis of each measurement item.
For example, reagent a = 100 μl for measurement item A, reagent b1 = 100 μl, b2 = 50 μl for measurement item B, reagent c1 = 100 μl, c2 = 50 μl for measurement item C, reagent d = 100 μl for measurement item D, measurement item E Reagent e
Information such as 1 = 200 μl and e2 = 200 μl.

When the setting of the measurement item for each sample is completed in the input setting mode, the calculating unit 34 reads the preset total number information and the reagent amount information, and the reagent usage amount is calculated based on these information. It For example, in the measurement item A, calculation calculation is performed such that the reagent usage amount = 100 (reagent amount information) × 5 (set total number) = 500 μl. The reagent usage amount information calculated in this way is stored in the storage unit 1 via the writing unit 32. When the reagent usage amount display mode is selected by operating the keys of the input unit 2, the reagent usage amount display mode signal is received by the reagent usage amount display means 35 to read out the reagent usage amount information from the storage unit 1, and based on this information. ,
As shown in FIG. 4, the reagent names 11 (a, b1, b2, c1,
The amount of reagent 12 to be used for each c2, d, e1, e2) is displayed on the display unit 4 as a list.

Although different reagents are used for each measurement item in this embodiment, when the same reagent is used for a plurality of measurement items, for example, the reagent c2 of item C shares the reagent b2. In this case, the addition operation of b2 = b2 + c2 = 250 [μl] is performed, and b2 = 250 is displayed to collectively display the reagent usage amount.

Further, as a method of notifying the operator of the shortage of the reagent, the remaining reagent amount of each reagent bottle of the automatic chemical analyzer is obtained, and the reagent usage amount is subtracted from the remaining reagent amount to obtain a negative value. It may be possible to display the corresponding reagent name and its insufficient amount on the display unit.

[0026]

In the automatic chemical analyzer of the present invention, when the measurement items are input and set, the preset total number of each measurement item is displayed on the display unit, so that it can be compared with the total number obtained from the worksheet or the like. It is easy to confirm input mistakes by work.
Further, when there are many measurement items, all the set items and the unset items are displayed in an identifiable manner, so that input errors of these items can be easily found.

Furthermore, since information about the required amount of reagent can be obtained before the analysis work, only the necessary reagents can be prepared, and there is no fear of running out of the reagent amount during the analysis work, and the analysis work is interrupted. Therefore, chemical analysis can be performed efficiently.
