Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a blood type determination support system and an operation method thereof.
[0002]
[Prior art]
In order to determine the suitability at the time of blood transfusion, it is essential to examine the ABO blood group and the Rh blood group, and these blood groups are widely determined in hospitals and clinical laboratories.
[0003]
In the ABO blood group classification, those having type A antigen are type A, those having type B antigen are type B, those having both type A and B type antigens are type AB, type A antigens and type B antigens Those having neither of these are classified as O type. The A-type plasma contains an anti-B antibody (referred to as “anti-B”) that causes an antigen-antibody reaction with B-type red blood cells to cause aggregation, and the B-type plasma reacts with an A-type red blood cell with an antigen-antibody reaction. Anti-A antibody (referred to as “anti-A”) that causes aggregation, AB type plasma contains neither anti-A nor anti-B, and type O plasma contains both anti-A and anti-B. included. Thus, ABO blood group can be determined by examining antigens on red blood cells (referred to as “front test”) or by examining antibodies in plasma (referred to as “back test”), In order to avoid a determination error, both the front test and the back test are performed, and the final determination of the blood type is performed after confirming that the determination results of both tests match.
[0004]
The front test is carried out by centrifuging the test blood into a plasma part and a blood cell part, reacting the blood cell part in different containers with standard anti-A and standard anti-B, and observing the degree of aggregation. In the back test, the plasma portion of the test blood is reacted with standard A blood cells (referred to as “A1”) and standard B blood cells (referred to as “B”) in different containers, and the degree of aggregation is determined. This is done by observing.
[0005]
In the Rh blood group classification, red blood cells having D antigen are classified as Rh + type, and those having no red antigen are classified as Rh− type. This is done by reacting the blood cell portion of the test blood with standard anti-D and observing the degree of aggregation. In the Rh blood group classification, the antigen on the red blood cells of the test blood is examined, so it is performed as a part of the front test of ABO blood group determination.
[0006]
Therefore, in order to perform blood type determination for determining suitability at the time of blood transfusion, the blood cell portion of the test blood is reacted in a container different from anti-A, anti-B and anti-D, and the test is performed. It is necessary to react the plasma part of the blood in a different container from A1 and B. For this reason, at least the operation of dispensing the test blood into these five separate containers and the operation of recording the degree of aggregation in each container are necessary.
[0007]
Conventionally, these operations are performed manually. In hospitals and clinical laboratories, it is necessary to determine the blood types of a large number of patients within a limited time. For this reason, a plurality of specimens are often tested concurrently. In order to prevent sample mix-up and mix-up of reagents to be added, labels are attached to the original sample and each test container, and each container has “anti-A”, “anti-B”, “anti-D”, Characters such as “A1” and “B” are described, and the same sample number is described in the original sample and each test container. The examiner confirms that the number of the original sample and the number of each test container match at the time of dispensing, and that the reagent to be added matches the reagent name displayed on the label of each test container. Make sure that you are working. Furthermore, in order to prevent human error, the front test and the back test are performed by different inspectors, and the final determination is performed only when the determination results match. The determined blood type is written on the worksheet by the examiner.
[0008]
[Problems to be solved by the invention]
In the conventional method, since the front test and the back test are performed by different persons, two examiners are required to determine the blood type for one specimen. However, there are not a few cases where blood type determination must be performed urgently at midnight, for example, to treat a traffic accident injury that occurred at midnight. However, in order to cope with such an emergency situation, it is difficult to have two examiners on standby 365 days a year, and in the case of an emergency, one examiner performs blood type determination. There are things that must be done. However, even in such a case, since the blood type determination is related to the life of the patient, mistakes are never allowed.
[0009]
An object of the present invention is to provide a blood type determination support system and an operation method thereof that can reliably determine a correct blood type without causing human error even when a single examiner performs a test. .
[0010]
[Problems to be solved by the invention]
As a result of diligent research, the inventors of the present application affixed barcodes with the same basic part and different branch number parts to the original sample and the test container, and made the computer read these barcodes immediately before each dispensing operation. If a mistake has occurred, a warning is issued and the next step cannot be entered or the cohesion degree cannot be entered, and the cohesion degree input field for a specific test container determines the cohesion degree. By making the bar code affixed to the test container to be read automatically displayed on the display by a computer, human error can be surely prevented.

[0012]
DETAILED DESCRIPTION OF THE INVENTION
A preferred embodiment of the present invention will be described. The blood type determination support system of the present invention can be composed of a computer, a normal barcode reader (preferably a stationary type), and a normal printer. As the computer, a normal Windows (registered trademark) personal computer can be preferably used. An input device such as a keyboard and a mouse, a display, and a printer (preferably a color printer) are connected to the computer. In addition, the computer includes a recording device such as a main memory including a CPU and a RAM, and a hard disk, and a control program for performing the method of the present invention is installed using such a hardware configuration device. As the system hardware, any commercially available hardware can be used.
[0013]
Next, a preferred specific example of the blood type determination support system of the present invention will be described together with a preferred operation method (usage method).
[0014]
Currently, blood collected from patients in hospitals, etc. is stored on-site in original specimen containers (also referred to as “parent specimens”) that are labeled with barcodes. And so on.
[0015]
When performing the method of the present invention, first, a control program installed in a recording device such as a hard disk is started, and then the barcode of the original sample container is read by a barcode reader. The read barcode is processed by a control program, and the same barcode as the barcode or a new barcode uniquely generated from the barcode (this portion is referred to as a basic portion of the barcode in this specification). A plurality of barcodes having different branch numbers are generated and printed from the printer. Here, the “new barcode uniquely generated from the barcode of the original specimen container” is not the same barcode as the barcode of the original specimen container, but the barcode of the original specimen container and the new barcode. This means that the barcode corresponds to 1: 1. By adopting such a new barcode, it is possible to use a barcode that is shorter than the barcode of the original sample container as a basic part, thereby improving the reading accuracy at the time of examination and improving work efficiency. It becomes possible. A bar code having a basic part and a branch number part can be easily generated by a bar code generating program programmed in the control program. An example of a plurality of barcodes to be printed is shown in FIG. In the example shown in FIG. 1, “child specimen”, “suspension liquid”, “front anti-A”, “front anti-B”, “anti-D”, “back A blood”, “back B blood”, “Du-prone” , Nine barcode labels with the label “Rh-cont” are printed. The bar code label is coated with glue on the back surface so that it can be peeled off from the mount and attached directly to the test tube. In addition to the barcode, a number is also displayed on the barcode label. FIG. 1 is a schematic illustration, and the barcodes are all the same, but the branch numbers are different in an actual barcode. Moreover, in order not to make a mistake in the reagent to be added, it is preferable to print different colors on the end portions of the bar code label of the test container for performing the aggregation test. For this reason, it is preferable to use a color printer as the printer.
[0016]
Next, each printed barcode label is peeled off from the mount and attached to each empty container (usually a test tube). In this specification, all containers for dispensing a part of a specimen or performing an agglutination test are called “test containers”. In a later step, the plasma portion of the original sample after centrifugation is dispensed to the test container to which the “child sample” barcode label is attached. In a later step, the blood cell portion of the original specimen after centrifugation is dispensed into the test container labeled “Floating liquid”, and then physiological saline is added to prepare a blood cell suspension. Is done. In a later step, the standard anti-A is added to the test container with the “front anti-A” label, and the blood cell suspension is dispensed from the “suspension liquid” test container to perform the agglutination test. Is called. In a later step, the standard anti-B is added to the test container with the “front anti-B” label, and the blood cell suspension is dispensed from the “suspension liquid” test container to perform the agglutination test. Is called. In a later step, the standard anti-D is added to the test container with the “anti-D” label, and the blood cell suspension is dispensed from the “suspension” test container to perform an agglutination test. . In a later step, plasma is dispensed from the “child sample” test container into the test container labeled “Back A Blood”, and standard A blood cells are dispensed to it to conduct an agglutination test. Is called. In a later step, plasma is dispensed from the “child sample” test container to the test container with the “Back B Blood” label, and standard B blood cells are dispensed there, and an agglutination test is performed. Is called. The test container with the label “Du” is used only when the result of the “anti-D” agglutination test is negative. Since most Japanese people are Rh + type, the aggregation test result of “anti-D” is almost positive. Even when the “anti-D” agglutination test result is negative, erythrocytes may have a Du antigen that causes an antigen-antibody reaction with anti-D, although antigenicity is weaker than D antigen. The presence or absence of the Du antigen is determined by examining whether or not aggregation occurs by sufficiently reacting with the anti-D at 37 ° C. for about 30 minutes to 1 hour. Therefore, when the aggregation with “anti-D” is negative, the standard anti-D is added to the test container to which the label “Du accuracy” is attached, and “floating liquid” is added thereto. A blood cell suspension is dispensed from the test container, and agglutination test is performed by reacting at 37 ° C. for 30 minutes to 1 hour. When weak aggregation is observed in the test container labeled “Rh-cont”, only the buffer used for the preparation of standard anti-D is added in the subsequent step, and “suspension liquid” is added thereto. The blood cell suspension is dispensed from the test container and the agglutination test is performed. In the agglutination test with anti-D, although non-specific agglutination may occur in spite of being Rh-type, a control test for confirming that aggregation does not occur by reacting with a buffer solution not containing anti-D Is done. Since “Du accuracy” and “Rh-cont” are not performed for most specimens, they may be peeled off from the label and attached to a test container only when these tests are required.
[0017]
After the original specimen is centrifuged to separate the plasma part and the blood cell part, the test is started.
[0018]
A control program is started, and a main form of a work management form stored in a recording device such as a hard disk is called and displayed on the display. The work management form includes a main form and a later-described subform that is called by clicking a button from the main form. An example of a main form of a preferred work management form is shown in FIG. In the main form of the work management form shown in FIG. 2, examinations for a plurality of patients can be displayed collectively. In the example shown in FIG. 2, in order to display the progress status of each process, each work process display column of “child sample”, “suspended liquid”, “back test sample”, and “front test sample” is provided. At the start, a plurality of black circles are displayed in each column. In addition, a work process display column for “Du specimen” is provided at a position across the column for displaying the aggregation result. A black circle is not displayed in the work process display column of “Du specimen”, but when “anti-D” aggregation is not positive, a black circle is automatically displayed. These work process display fields will be described later. Further, a submenu activation button (button for calling a subform) for each work is provided on each work process display column. When the “child sample dispensing” button is clicked with the mouse pointer, a child sample dispensing form as shown in FIG. 3, for example, appears. The same applies to the dispensing forms of “suspension liquid preparation”, “front test specimen dispensing” and “back test specimen dispensing” and “Du test specimen dispensing”. The form has a large area for displaying a warning when the inspector makes a mistake, and a column for displaying the contents of the mistake is provided below the large area. Further, there are provided columns for displaying the barcodes of the original sample or the barcodes uniquely generated therefrom and the numbers written on the barcode labels of the child samples, respectively. Further, an “aggregation degree input” button is provided in the main form, and clicking on this button displays an aggregation degree input form having an aggregation degree input field. Further, a “Du test” button is provided in the main form, and when this button is clicked, a Du test form having a cohesion degree input field in the Du test is displayed. Each of these subforms is of course stored in the hard disk or the like, and is called up by the control program and displayed on the display.
[0019]
The inspection procedure is determined in advance. In the following example, a case where the child sample dispensing, the back test, the suspension preparation, the front test (including anti-D), and the Du test are performed in this order will be described. Of course, the procedure is not limited to this.
[0020]
In the example of the test described here, since the child sample dispensing is performed first, the “child sample dispensing” button in the main form is clicked to display the child sample dispensing form as shown in FIG. In this state, the barcode of the original sample is read with a barcode reader. The read barcode or a barcode uniquely generated from the barcode is stored in the main memory. In the “read parent sample” field of the child sample dispensing form, the number described in the read barcode label or the number of the barcode uniquely generated from the barcode is displayed.
[0021]
Next, the barcode of the test container with the label “child sample” is read with a barcode reader. The control program compares the barcode of the original sample read earlier or the barcode uniquely generated from the barcode with the barcode of the child sample, and determines whether the basic part of the barcode is the same. Determine whether. Further, it is determined whether the branch number portion of the barcode of the child sample is the branch number of the container in the correct order stored in the container order file stored in the hard disk or the like. In the container order file, a predetermined container order is recorded corresponding to the branch number. That is, since the barcode attached to each test container has a branch number part, each test container is specified by this branch number part. If the inspection procedure is determined in advance, the order of the test containers read by the bar code reader can be determined from the beginning, and the determined order of the test containers is stored in the container order file by the branch number of the test container. Record it. In this way, reading the “child sample” barcode indicates whether the child sample test container is for testing the original sample patient (preventing mistakes between samples), The control program determines whether or not the test container read second (that is, next to the “original sample” container) is a “child sample” test container (prevents mistakes in the test container mix-up). The In the “read child sample” column, the number written in the barcode of the child sample is displayed. These also apply to the following steps.
[0022]
When the barcode of the original sample is first read, the first black circle of the two black circles in the “child sample” column of the work process display column of the main form of the work management form shown in FIG. 2 changes to a white circle. Next, when the barcode of “child sample” is read, the second black circle changes to a white circle. Thus, the inspector can always know at a glance which process he is currently performing by looking at the main form.
[0023]
If the inspector makes a mistake in the test container, that is, read the barcode of the “child sample” container for another patient different from the original patient, or use the same patient container as the original patient However, when the barcode of a container other than the “child sample” container is read, a warning is output by the control program and the barcode of the next process is disabled. The warning is performed, for example, by displaying a warning mark with “MISS” written on a red background as shown in the lower left form of FIG. 3 in the warning display field of the child sample dispensing form shown in FIG. . In the warning display column, if no mistake has occurred, for example, an OK mark as shown in the upper right form of FIG. 3 is displayed. The warning preferably further emits a warning sound.
[0024]
If a warning is issued due to a mistake, clicking the cancel button on the child sample dispensing form cancels the previous barcode reading, and 2 in the process confirmation column (and the work process display column on the main form). The first white circle returns to the black circle. In this state, the correct test container can be taken out and read by the bar code reader, and the subsequent steps can be continued. Note that the warning mode and the method for canceling the warning when a mistake is made are the same in the following steps.
[0025]
Next, the plasma portion is transferred from the original sample container to the child sample container that has been confirmed to be a correct test container as described above.
[0026]
In this test example, the back test will be performed next, so the child sample dispensing form will be closed (you can close it by clicking on the X in the upper right corner of the form) and the “Back test sample dispensing” button on the main form When is clicked, a back test sample dispensing form as shown in FIG. 4 is displayed.
[0027]
In this state, the barcode of the child sample container is read by a barcode reader, and then the barcodes of the test containers “Back A Blood” and “Back B Blood” are read by the barcode reader. Then, the basic portion of the barcode of the child sample container that has been read is stored, and it is compared whether or not it matches the basic portion of the barcode of each test container of “Back A Blood” and “Back B Blood”. The In addition, the branch number portion of the barcode of each test container of “Back A Blood” and “Back B Blood” is stored in the container order file, and the barcodes read fourth and fifth from the beginning are read. It is determined whether the branch number matches. Therefore, in exactly the same way as in the case of child sample dispensing, are the “back A blood” and “back B blood” test containers and the “child sample” test containers used to test the same patient? No (prevention of mistakes between specimens) and whether the 4th and 5th test containers counted from the beginning are “Back A Blood” and “Back B Blood” test containers Both (prevention of mistakes in test container mix-up) are judged by the control program. In addition, since the same plasma in the child sample container can be put into the test containers for “Back A blood” and “Back B blood”, the order of “Back A blood” and “Back B blood” is switched. There is no problem. Therefore, the order in which these orders are switched may be recorded in the container order file so that it is acceptable in either case. Further, the back test sample dispensing form shown in FIG. 4 has a process confirmation column similar to the work process display column of the main form, and the display of the process confirmation column and the work process display column of the main form is also a child. Changes in the same manner as in the case of sample dispensing. However, since it is dispensed into two test containers, “Back A Blood” and “Back B Blood”, the total number of barcodes read by the barcode reader is three. Accordingly, three black circles are displayed in the process confirmation column and the work process display column. The second black circle and the third black circle are preferable because they are more obvious when they are displayed in different colors other than white. After confirming that each of the “back A blood” and “back B blood” test containers is a correct container, plasma is dispensed into these test containers from the child specimen container.
[0028]
Next, standard type A blood cells (A1) are added to the “back A blood” test container, and standard type B blood cells (B) are added to the “back B blood” test container. Agglomeration in these test containers is observed later.
[0029]
In this test example, a suspension is then prepared. Close the back test specimen dispensing form and click the “preparation of suspension” button to display a suspension preparation form similar to that shown in FIG.
[0030]
In this state, the barcode of the original sample is read with a barcode reader, and then the barcode of the “floating liquid” container is read with the barcode reader. Just as in the case of child sample dispensing, whether or not the suspension test container is for testing the original sample patient (preventing mistakes between samples) and from the beginning The control program determines whether or not the seventh read test container is a “suspension liquid” test container (prevents mistakes in the test container misplacement). The black circles in the process confirmation column and work process display column also change in exactly the same manner as in the case of child sample dispensing.
[0031]
After confirming that the “suspended liquid” container is the correct container, a part of the blood cell portion of the original specimen is transferred to the “suspended liquid” container with a dropper. Next, physiological saline is added thereto to prepare a blood cell suspension.
[0032]
Next, the front test is performed. Close the suspension preparation form and display the table test specimen dispensing form. In this state, the barcode of the “floating liquid” container is read by a barcode reader, and then the barcode of each of the “anti-A”, “anti-B”, and “anti-D” containers is read by the barcode reader. Then, in the same manner as in the case of the back test specimen dispensing, the “anti-A”, “anti-B”, and “anti-D” test containers and the “floating liquid” test containers perform the same patient examination. (Prevention of mistakes between specimens) and the 9th, 10th and 11th test containers read from the beginning are “anti-A”, “anti-B”, “ Whether or not each of the test containers of “anti-D” is a test container (prevents mistakes in the test container mix-up) is determined by the control program. In addition, since the same suspension liquid in the suspension liquid container is put in each of the “anti-A”, “anti-B”, and “anti-D” test containers, “anti-A”, “anti-B”, “ There is no problem even if the order of “Anti-D” is changed. Therefore, the order in which these orders are switched may be recorded in the container order file so that it is acceptable in either case. In addition, the display in the process confirmation column of the front test sample dispensing form and the work process display column of the main form also changes in the same manner as in the case of child sample dispensing. However, since it is dispensed into three test containers, each of the “anti-A”, “anti-B”, and “anti-D” test containers, the total number of barcodes read by the barcode reader is four. Accordingly, four black circles are displayed in the process confirmation column and the work process display column. The second to fourth black circles are preferable because they are more obvious when they are displayed in different colors other than white. After confirming that each of the “anti-A”, “anti-B”, and “anti-D” test containers is a correct container, the blood cell suspension is dispensed into these test containers from the suspension container.
[0033]
Next, anti-A, anti-B, and anti-D are added to the test containers of “anti-A”, “anti-B”, and “anti-D”, respectively. Mix well and immediately centrifuge.
[0034]
Next, the determination of the degree of aggregation and its input are performed. When the table test specimen dispensing form is closed and the “aggregation input” button is clicked on the main form, an aggregation input form as shown in FIG. 5 is displayed on the display. Of course, this subform is also stored on the hard disk.
[0035]
In this state, the barcode reader reads the barcode of the “Back A Blood” test container. Then, based on the read barcode, the control program displays an aggregation degree input form having an input field for inputting the degree of aggregation of the “back A blood” of the patient. The numerical value input in this input field is processed as the degree of aggregation of the “back A blood” container of the patient. Therefore, the transcription mistake which inputs the result of another patient's container and the other patient's test container of the same patient is prevented. In addition, the bar code number read by the bar code reader is displayed in the “Reading specimen” column of the agglutination degree input form. Based on the branch number, the test is performed in the column “The specimen is ...”. The contents are displayed (in FIG. 5, the case of anti-A in the table test is displayed). The inspector visually determines and inputs the degree of aggregation according to a correspondence table as shown in the lower right of FIG. When entered, the degree of aggregation is displayed largely in the “Result Display” field.
[0036]
Next, in the same manner, the barcode of the “Back B Blood” test container is read with a barcode reader, and the degree of aggregation is input in the displayed input field. Further, in the same manner, the “anti-A”, “anti-B”, and “anti-D” test containers are also read by the barcode reader, and the aggregation degree is input in the displayed aggregation degree input column each time. . In addition, since the cohesion degree input field displays the cohesion degree input field of the test container specified by the read barcode, the order of the containers for inputting the cohesion degree does not need to be determined in advance. It can be carried out. This increases work efficiency.
[0037]
If “Du accuracy” and “Rh-cont” are required, click the “Du test sample dispensing” button and click on the subform similar to “Back test sample dispensing”. After displaying, dispense the “suspended liquid” using the barcode, click the “Du test” button, read the barcode with a barcode reader in the same way as above, and then cohesive force Enter.
[0038]
When the coagulation degree input for each test container is completed, the control program compares the blood type determination table stored in the hard disk with the input result to determine the blood type. The determined blood type is displayed on the main form of the work management form.
[0039]
Further, if desired, the blood type certificate and / or the patient recognition wristband may be created by means of outputting together with patient information such as the determined blood type and patient ID barcode and the patient name and printing. . The blood type certificate (blood type card) can be in a form as shown in FIG. 6, for example. Further, for example, a blood type test confirmation list as shown in FIG. 7 may be printed as desired.
[0040]
Further, the test result data may be transmitted to a host computer of a clinical laboratory center or a computer of a client hospital. Furthermore, if the patient has been previously tested at the same clinical laboratory, etc., and the data is stored on the host computer, the test results are stored in the patient's past data stored on the host computer. The accuracy of the inspection can be further improved by collating with the history data. By such a collation, there may be a case where an error such as mistaking the patient at the stage of blood collection can be found.
[0041]
An example of the system configuration of the blood type determination support system described above is shown in FIG.
[0042]
【The invention's effect】
According to the present invention, even when one examiner performs a test, a human error does not occur, and a correct blood type can be reliably determined.
