BACKGROUND OF THE INVENTION
The present invention relates to an automatic analyzer capable of calculating a necessary reagent amount from a past analysis amount and performing inventory management based on reagent information in one or more devices.
[0002]
[Prior art]
Conventionally, in an automatic analyzer, in order to manage the reagent amount in each reagent container held in the reagent store, the reagent amount in each reagent container in the reagent store is detected by the reagent amount detection mechanism, The reagent amount is displayed for each item on the display device based on the detection signal.
[0003]
Japanese Patent Application Laid-Open No. 5-164760 discloses that a control unit selects measurement items for samples in each sample container, measurement parameters such as reagent amounts for each measurement item, and each reagent detected by the reagent amount detection means. Enter the reagent remaining amount in the bottle and calculate the reagent amount necessary for measurement from the number of measurement samples for each reagent and the amount of each reagent used, and display the reagent necessary amount on the display device together with the reagent remaining amount, or reagent An automatic analyzer that also displays the shortage is disclosed.
[0004]
According to the automatic analyzer having the above-described configuration, the operator can check the amount of reagent installed in the apparatus. In this case, the operator checks the amount of reagent loaded in the device and the number of samples to be analyzed on the day, checks whether it is necessary to add a reagent, and adjusts the amount of reagent loaded. It was.
[0005]
[Problems to be solved by the invention]
As described above, in order not to run out of the reagent during the analysis, the operator has to operate while constantly monitoring the amount of the loaded reagent and the number of samples to be analyzed, which is a heavy burden.
[0006]
In addition, if a shortage occurs in the reagent loaded in the apparatus during the analysis, the analysis is interrupted. Therefore, adding a reagent and performing the analysis again wastes time.
[0007]
Furthermore, in the automatic analyzer disclosed in the above-mentioned JP-A-5-164760, the necessary amount of reagent is calculated from the item selection information. The item selection information is prepared in advance with a sample, It is not possible to know how much reagent is needed unless you check what kind of reception you want before accepting the analysis.
[0008]
The present invention has been made in view of the above circumstances, and can reduce the burden on the operator and can perform reagent inventory management without running out of the amount of reagent loaded in the apparatus during the analysis. Is intended to provide.
[0009]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0015]
FIG. 1 is a functional block diagram showing a configuration of an automatic analyzer according to an embodiment of the present invention.
[0016]
In FIG. 1, the automatic analyzer 1 is connected to an external host (HOST) computer 10. The host computer 10 supplies the number of received items to the analysis / calculation unit 12 together with the received items input by the item receiving unit 11 configured with, for example, a keyboard. The analysis result obtained by the analysis / calculation unit 12 is output to and stored in the data storage unit 14.
[0017]
In addition to the above analysis results, the data storage unit 14 is supplied with inventory quantity data from the reagent inventory information input unit 15 outside the automatic analyzer 1 and an initial determination value from the reagent excess / deficiency manual determination value input unit 16. Is done. The various data stored in the data storage unit 14 includes the reagent remaining amount detected by the reagent remaining amount detecting unit 17 and the correction value obtained from the determination correction value input unit 18, as well as reagent / overstock shortage. It is supplied to the determination unit 20.
[0018]
Further, the result determined by the reagent / stock excess / deficiency determination unit is displayed on a determination value display unit 21 constituted by a CRT display or the like.
[0019]
In such a configuration, in the analysis / calculation unit 12, reagent information and the like for each specimen previously measured by the analyzer is input from the host computer 10. On the other hand, an item, a past period to be analyzed, and the like are input from the item receiving unit 11 to be received for each sample. The analysis / calculation unit 12 obtains an analysis result for a predetermined period analyzed in the past based on the information described above. The analysis result obtained here is stored in the data storage unit 14.
[0020]
Then, the current reagent inventory amount is input from the reagent inventory information input unit 15 and stored in the data storage unit 14. Further, from the reagent excess / deficiency manual determination value input unit 16, a determination value for determining the reagent excess / deficiency fee is input to the data storage unit 14 and stored as an initial determination value. Further, the data storage unit 14 stores measurement parameters such as a reagent dispensing amount corresponding to each measurement item used at the time of calculation processing in the reagent / stock excess / deficiency determination unit 20.
[0021]
The reagent / stock excess / deficiency determination unit 20 receives the reagent remaining amount detected by the reagent remaining amount detection unit 17 and the correction value from the determination correction value input unit 18. At the same time, the reagent / stock excess / deficiency determination unit 20 reads out the data stored in the data storage unit 14 and executes a calculation to execute a reagent amount necessary for measurement, that is, a reagent necessary amount and a reagent shortage amount. Is required.
[0022]
The determination value display unit 21 displays the result determined by the reagent / overstock shortage determination unit 20 based on the various types of input information.
[0023]
By the way, when the sample is set on the tray (not shown) by the operator, the reagent remaining amount detected by the reagent remaining amount detection unit 17 in the reagent / overstock shortage determination unit 20 is set for the set sample. Information about the quantity is supplied. At the same time, information on items received in the past stored in the data storage unit 14 is read out. Then, the reagent / stock excess / deficiency determination unit 20 calculates a concentration or activity value of the target substance in the sample by performing a predetermined calculation based on the physical quantity of the reagent, and displays the determination value display unit 21 on the determination value display unit 21. The result is displayed.
[0024]
Here, the information of the items received in the past stored in the data storage unit 14 is, for example, what kind of reagent was necessary for the target sample in the past predetermined period. It is a representation.
[0025]
FIG. 2 is a diagram illustrating an example of a determination value setting screen displayed on the determination value display unit 21. In this case, in the “automatic setting mode”, the acceptance period of the sample to be extracted is from April 1, 2000 to March 31, 2001, and the acceptance items are set for each day of the week. That is, since the result received in the period is the past analysis amount, these are divided into items for each day of the week (Monday to Sunday). Based on the past analysis amount, the expected number of analyzes of each reagent is displayed for each day of the week in the reception item section. The expected number of analyzes is determined as the amount of reagent necessary for measurement from the number of samples to be measured for each reagent and the amount of each reagent used.
[0026]
At this time, the number of predicted analyzes can be changed by the determination correction value input unit 18. Since the above-mentioned predicted analysis number is for the past received items stored in the data storage unit 14, it can be changed when it is necessary to change the predicted analysis number by an operator input.
[0027]
For example, in the determination value setting screen shown in FIG. 2, it can be seen that for most reagents, the number of analyzes on Wednesday and Thursday is large. This is based on the judgment that the number of Wednesdays and Thursdays increases from past data (data in the above period), and the predicted number of analyzes as shown in the figure is calculated.
[0028]
In the above-described example, the case of automatic setting has been described. However, when the tab of the determination value setting screen shown in FIG. 2 is clicked with a mouse or the like, the screen is switched to the “manual setting mode” screen. In this case, all the above-described predicted analysis numbers are manually input by the operator.
[0029]
FIG. 3 is a diagram illustrating an example of an inventory management screen.
[0030]
In FIG. 3, reagents are entered in the item names, and the number of boxes used for these reagents and the inventory quantity of the reagents are displayed. The remaining amount is calculated by the reagent / stock excess / deficiency determination unit 20 based on the value input from the reagent inventory information input unit 15 .
[0031]
FIG. 4 is a diagram showing a display example of the excess / deficiency prediction screen.
[0032]
This excess / deficiency prediction screen is calculated based on the information on the determination value setting screen shown in FIG. 2 and the inventory management screen shown in FIG. In the excess / deficiency prediction screen shown in FIG. 4, columns of predicted number, R1 remaining amount, and R2 remaining amount are displayed from the left for each reagent. Further, fields of R1 excess / deficiency and R2 excess / deficiency are displayed from the predicted number, the remaining R1 amount, and the remaining R2 amount.
[0033]
In this case, it can be seen that the reagents GPT and GOT are deficient in both R1 and R2, and the reagent CHO is deficient in R2. Further, in FIG. 4, the hatched column indicates that the reagent is in stock, and the reagents GPT and CHO correspond to this. Also, the shaded columns in FIG. 4 indicate that there is no inventory, and the reagent GOT corresponds to this. That is, the operator can easily recognize the reagent that is expected to be deficient by viewing the excess / deficiency prediction screen so that the reagent can be distinguished from the other columns.
[0034]
Therefore, the operator can easily grasp the reagent inventory information by looking at such an excess / deficiency prediction screen.
[0035]
In the above-described embodiment, the column in which the amount of reagent necessary for analysis is insufficient has been described with diagonal lines or shaded display. However, it is only necessary to distinguish the insufficient column on the display screen. You may make it display in a different color.
[0036]
Furthermore, notification means such as a warning sound may be used as long as it alerts the operator when the amount of reagent necessary for analysis is insufficient.
[0037]
In addition, since the amount of reagent used is assumed based on the data of what kind of analysis was performed in the past, it is easy to predict the necessary amount of reagent that is different from normal because of the tendency in a specific period.
[0038]
As described above, according to the present embodiment, since the required analysis amount or the reagent usage amount is calculated based on the analysis amount analyzed in the past, the tendency can be easily grasped. Since the amount of reagent required for analysis and the amount of assumed reagent used calculated from the analysis information are displayed on the same screen, the operator can easily grasp the excess or deficiency of the reagent. This makes it easy to manage reagent inventory.
[0039]
Further, the calculation of the amount of reagent necessary for analysis in the past and the assumed amount of reagent may be set not only for each day of the week, but also for example, in units of seasons or hours, and allowances may be set. In this case, since the manual determination value has one or more patterns, it is possible to deal with an event that occurs irregularly, for example, a sudden request for a mass screening.
[0040]
By doing in this way, it becomes possible to calculate the amount of reagent used for analysis in an amount that is as close as possible to the required amount without excess or deficiency.
[0041]
【The invention's effect】
As described above, according to the present invention, the burden on the operator can be reduced, and the reagent inventory can be managed without interrupting the analysis because the amount of the reagent loaded in the apparatus is insufficient during the analysis. An analysis device can be provided.
