Abstract

PROBLEM TO BE SOLVED: To easily evaluate the reliability by providing an input means for preliminarily inputting a correlation data showing a correlation, a storing means for storing this data, a judging means and an output means. SOLUTION: A data receiving part 4 receives, for example, the measurement data supplied from an urine precipitation inspecting device 2 and an urine qualitative inspecting device 3 direct or through a communication circuit, and inputs it to a CPU 5. The measurement data received by the receiving part 4 is stored in the measurement data memory 6a of a RAM 6 through the CPU 5. The rank and correlation data inputted by a keyboard 7 are stored in the rank setting memory 6b and correlation data memory 6c of the RAM 6, respectively. When the correlation data showing the correlation between erythrocyte (RBD) and occult blood (OB), for example, is preliminarily inputted by the keyboard 7, and the data for RBC from the device 2 and the data for OB from the device 3 are received by a data check device 1, the CPU 5 judges whether the measurement data is suitable to the correlation data or not.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for checking measurement results in a clinical test, and more particularly to an apparatus for mutually determining reliability of a plurality of types of test results such as a urine qualitative test and a urine sediment result.

[0002]

2. Description of the Related Art Conventionally, two major urine tests are known: a qualitative test and a sediment test. In other words, in a qualitative test, generally, a test strip to which a reaction test strip for each measurement item is attached is dipped in a urine sample to be tested for a predetermined time, and the color of the test strip is compared with a reference color for determination. (-)
(±) (+) ... Is automatically obtained (see, for example, Japanese Patent Laid-Open No. 2-27262). In the sediment examination, formed particles in the urine sample to be examined are automatically classified and counted (see, for example, JP-A-5-322885).

[0003]

By the way, in the urine qualitative test, an erroneous measurement result may occur due to an interfering reaction depending on the item. For example, occult blood (OB) reacts to the false negative side due to the inclusion of ascorbic acid or the like, and to the false positive side due to the inclusion of hypochlorous acid or the like.

Therefore, there is a demand for an apparatus for easily determining the reliability of the inspection result of each measurement item in the qualitative inspection. Further, with such a determination device, the determination condition may differ depending on the usage state, and therefore it is necessary to arbitrarily set and change the determination condition without error.

The present invention has been made in consideration of such circumstances, and the reliability thereof can be easily evaluated by measuring the same measurement object for a plurality of measurement items and mutually checking the obtained measurement data. The present invention provides a data check device capable of doing the above.

[0006]

The present invention provides a first measurement item and a second measurement item obtained by measuring the same measurement object with a plurality of inspection devices including a first inspection device and a second inspection device. Accepts measurement data of multiple measurement items including
A data check device for mutually checking the measurement data of the plurality of measurement items, and an input unit for previously inputting correlation data indicating a correlation between the plurality of measurement items, and a storage unit for storing the input correlation data. The present invention provides a data check device including a determination unit that determines whether or not the received measurement data matches the correlation data, and an output unit that outputs the determination result of the determination unit. For the measurement data of a plurality of measurement items (first measurement item, second measurement item, ...), the same measurement target should be measured by a plurality of inspection devices (first inspection device, second inspection device, ...). Can be obtained by

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, the measurement target is, for example, urine of mammals including humans. Further, in the present invention, for example, a urine sediment inspection device is applied to the first inspection device, and a urine qualitative inspection device is applied to the second inspection device.

Further, the measurement items by the urinary sediment inspection device are
If at least one selected from red blood cells, white blood cells, casts and bacteria, and the measurement item by the urine qualitative test device is at least one selected from occult blood, protein, nitrite and white blood cells, the correlation data is From the viewpoint of the strength of the correlation, it is preferable that the relationship is set for at least one combination selected from red blood cells and occult blood, white blood cells and white blood cells, casts and proteins, and bacteria and nitrite.

A tablet or a keyboard may be used as the input means. The storage means and the determination means are CPU, R
It can be configured by a microcomputer including OM and RAM. A CRT, a liquid crystal display, or a printer may be used as the output means.

The urinary sediment inspection device may be a device that analyzes formed elements contained in urine with a flow cytometer and outputs the analysis result. The urine qualitative test device may be a device that immerses a urine test strip in urine and outputs the degree of discoloration of the test strip.

When the stored correlation data is represented by a coordinate area having a plurality of measurement items as parameters, the determining means determines whether the coordinates of the received measurement data are in the area or to what extent. The degree of correlation of measurement data can be determined. When the plurality of measurement items is two (the first measurement item and the second measurement item), the correlation data is represented by an area on a two-dimensional coordinate. Two-dimensional coordinates
The measurement data of the first and second items may be composed of the coordinates of the cells divided into a plurality of ranks, and the correlation data may be input in units of the cells.

In the present embodiment, the urinary sediment examination apparatus 2 uses a known apparatus that automatically analyzes formed elements contained in a urine sample by a flow cytometer and outputs the numerical value of the analysis result as measurement data. In the urine qualitative test device 3, a urine test paper is dipped in a urine sample, and the degree of discoloration of the test paper is automatically classified into 9 levels, and the corresponding symbols (-), (±), (+), (2+), (3 +), ...
A well-known device that outputs (7+) as measurement data is used.

The data receiving unit 4 receives, for example, measurement data supplied from the urine sediment testing device 2 and the urine qualitative testing device 3 directly or via a communication line and inputs them to the receiving CPU 5.

The measurement data received by the data receiving unit 4 is stored in the measurement data memory 6a of the RAM 6 via the CPU 5. Reference numeral 7 is a keyboard for inputting correlation data, measurement items, and ranks for dividing the measurement range.

The rank and correlation data input by the keyboard 7 are stored in the rank setting memory 6b and the correlation data memory 6c of the RAM 6, respectively. RO
M9 stores a control program for controlling the CPU 5 in advance, and the CRT 8 displays various set data, measurement data, determination results, and the like.

The urinary sediment inspecting device 2 performs measurement by classifying and counting quantitative measurement items.
Quantitative measurement items include red blood cells (RBC), white blood cells (W
BC1), epithelial cells (EC), casts (CAST) and bacteria (BACT).

The urine qualitative test device 3 measures the qualitative measurement items with a urine test strip. The qualitative measurement items include occult blood (OB), protein (PRO), nitrite (NIT) and white blood cells (WBC2). ) Is given. Then, as a combination having a deep correlation between quantitative and qualitative measurement items, RBC1 × OB, WBC1 × WBC
2, a combination of CAST × PRO and BACT × NIT can be given.

Therefore, for example, the correlation data indicating the correlation between RBC and OB is input in advance by the keyboard 7, and the measurement data of RBC from the urine sediment testing device 2 and the measurement data of OB from the urine qualitative testing device 3 are input. However, when each is accepted by the data check device 1,
The CPU 5 determines whether the set of received measurement data matches the correlation data, and displays the determination result on the CRT 8.

A more detailed operation in such a configuration will be described below. First, the procedure for setting the correlation data indicating the correlation of each measurement item will be described with reference to the flowchart of FIG.

FIG. 2 is a key arrangement diagram of the keyboard 7,
When the setting key K1 and the rank setting key K2 are pressed (steps S1 and S2), the rank setting mode is set, and the CRT8
A rank setting screen as shown in FIG. 3 is displayed, and the key K6 is further pressed to select RBC, which is one of the quantitative measurement items (step S3).

Therefore, as shown in FIG. 3, the lower limit value (LL) and the upper limit value (UL) of the RBC are assigned to each of the ranks (Rank) 0 to 8 on the screen by using the cursor key K14 and the ten key K15.
To set (step S4). Then, the end key K16 is pressed to finish the rank setting for RBC (step S5).

In FIG. 3, the upper limit of the rank 7 (U
L) is set to "0", which means "infinity", indicating that rank 8 has no set value.
Similarly, by using keys K7, K8, and K9, WBC,
After selecting CAST and BACT and setting the lower and upper limit values corresponding to ranks 0 to 8, return key K1
Press 7 to exit the rank setting mode (step S
6).

Next, when the setting key K1 and the cross check key K3 are pressed (steps S1 and S7), the area setting mode is set and the CRT 8 displays the area setting screen shown in FIG.

The area setting screen is provided with two-dimensional coordinates in which the horizontal axis is a quantitative measurement item (SEDIMENT) and the vertical axis is a qualitative measurement item (DIPSTICK). Each axis is divided into 9 ranks, respectively Corresponding area setting cells are provided.

The nine ranks 0 to 8 on the horizontal axis correspond to the numerical values shown in FIG. 3 set in the rank setting mode. Further, in the nine ranks 0 to 8 on the vertical axis, (−), (±) of the measurement results obtained from the urine qualitative test device 3,
Correspondences are set in advance in the ROM 7 so that (+), (2 +), ..., (7+) respectively correspond.

Then, the key K10 is pressed to select RBC × OB which is one of the cross check items (step S8). Then, as shown by the hatched area in FIG. 4, an area in which RBC and OB have a correlation, that is, a matching area is set in units of cells using the cursor keys K14 and K4 (step S9).

When deleting the set matching area, the cursor keys K14 and K5 can be used to delete the cells in units of cells. And the end key K16
Press to complete the area setting for RBC × OB (step S10).

Similarly, the keys K11, K12 and K13 are used to sequentially perform WBC × WBC, CAST × PRO and BACT.
When xNIT is selected and each matching area is set and the return key K17 is pressed, the area-set mode ends (step S11).

Next, when the execution key K18 is pressed, the execution mode is entered, and the respective measurement data measured by the urine sediment testing device 2 and the urine qualitative testing device 3 for the same urine sample are read from the measurement data memory 6a, and the CRT 8 is operated. Is displayed as shown in FIG.

6A and 6B show scattergrams created by the measurement data from the urine sediment inspection device 2, and FIG. 6 shows the urine sediment inspection device 2 and the urine qualitative inspection device 3.
Of the items common to the measured data from
Data of RBC, WBC, EC, CAST, and BACT are shown, and D of FIG. 6 shows data of other items, that is, OB, PRO, and NIT data from the urine qualitative test device 3.

Then, RBC × OB, WBC × WBC,
It is determined whether or not the correlation in each combination of CAST × PRO and BACT × NIT is within the matching area (FIG. 4) set in the area setting mode,
Items that do not exist in the matching area are displayed with the symbol “?” Added to the data indicated by C and D in FIG.

In the example of FIG. 6, "?" Is added to "2+" of OB for "375.9" of RBC. This is because the data of this combination does not exist in the matching area shown in FIG. 4 as a result of the cross check,
That is, in FIG. 4, it is confirmed that the matching area does not have a measure represented by rank 6 on the horizontal axis corresponding to “375.9” and rank 3 on the vertical axis corresponding to “2+”.

FIG. 6 shows that the data to which "?" Is added has low reliability, and the other data has high reliability. In this way, by cross-checking the data measured by the urine sediment inspection device 2 and the urine qualitative inspection device 3, it is possible to confirm the mutual reliability of the data.

Further, in the area setting screen in which the matching areas are displayed as shown in FIG. 7, it is preferable that a symbol * indicating the measurement result is displayed in the corresponding grid of the measurement data. With this, it is possible to see at a glance how much the measurement data deviates from the matching area, and to confirm the degree of reliability of the measurement data.

In this embodiment, the measurement data range corresponding to each of ranks 0 to 8 on the vertical axis of FIG.
Although it is set in the OM 9, the user may arbitrarily set it in the rank setting memory 6b as in the case of the rank on the horizontal axis. The data check device 1 can be built in either the urine sediment test device 2 or the urine qualitative test device 3. The qualitative measurement items occult blood and white blood cells may be represented as (OB / Hb) and (L.EST.), Respectively.
