BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a two-dimensional bar code for exchanging information between a medical department and an examination department using a two-dimensional bar code in order to manage medical information of a subject. Regarding the method of requesting and reporting the specimen test used.

[0002]

2. Description of the Related Art Conventionally, in a relatively large hospital,
Hospital Information System (HIS)
A computer system referred to as is introduced and constructed, and it is becoming possible to centrally manage medical information of a subject.

For sample testing, for example, input of request information, data collection from an analyzer, quality control,
Inspection reports and the like have been made online, and doctors are now able to input and refer to these information from terminal devices in the examination room or ward.

Further, in recent years, an optical card is provided for each examinee, medical information of each examinee is recorded on the optical card, and the optical card is referred to as needed, whereby medical treatment with high investment efficiency is achieved. Attempts have been made to build information systems.
Such a system can be constructed if there are a small number of personal computers and an optical card reader / writer device connected thereto, and a large computer or a large-scale LAN system is unnecessary.

However, since small and medium-sized hospitals and clinics do not have such inspection equipment, it is necessary to request an external inspection center for sample inspection. further,
In such a small-to-medium-sized hospital, the above-mentioned HIS could not be introduced due to the budget limitation, and the medical information of the subject was managed by a paper chart.

[0006] In hospitals and clinics that outsource the sample inspection, the inspection request slip and the sample contained in the sample container are sent to the inspection center to request the inspection. The test request slip includes the test subject number, test subject name, test subject gender, test subject birth date, and other test subject attribute information, test request date, test request item, and sample container number used for sample collection. Is described. These items are often handwritten, and in addition to slips, a computer external recording medium such as a floppy disk is used, and the test request information regarding the sample of the day is often written and handed to the recording medium.

Furthermore, an inspection information system for processing the inspection information based on the information described in the inspection request slip is installed in the inspection center that accepts the inspections from such hospitals and clinics. Registration, collection of inspection results obtained from various analyzers, quality control of inspection data, printing of inspection result reports, billing of costs, etc. At the inspection center, distribute the sample container such as a test tube to which a label with the sample container number printed in advance with letters and bar code and the inspection request slip dedicated to the center are distributed to the customer's hospital or clinic. Is also widely practiced.

The items described in the inspection request slip from the hospital / clinic are manually input by a key punch or by reading a floppy disk sent together with the request slip from the requesting hospital or clinic. A worksheet is created for each analyzer based on the inspection request information thus input, and the worksheet information is downloaded to each analyzer.

On the other hand, the sample is subjected to pretreatment such as centrifugation and set in the analyzer. This analyzer is equipped with a bar code reader, reads the sample container number from the bar code attached to the sample container, searches the worksheet information using it as a key, and knows the inspection item of the sample, Analyze specified items. Further, the analyzer obtains data on designated items for each sample. For this data, a data cleaning process is performed. As a cleaning method, the X-bar R control chart method, the Qsum method, the twin plot method, and the like using a quality control sample are widely used. The data thus cleaned is collected for each subject in the examination information system and finally printed on the examination result report. Then, the printed test result report is sent to the requesting hospital or clinic, and is usually bound in the patient chart.

In addition to the test report, the test center sends a test result report on a recording medium such as a floppy disk, and at a hospital or clinic, the information recorded on the recording medium is input to a personal computer. Record on the subject's optical card.

[0011]

[Problems to be Solved by the Invention] However, the items described in the inspection request slip from the conventional hospital / clinic are as follows.
For example, although it is manually input to the inspection information system, this method requires acquisition of a key bunch, and an input error is likely to occur when the key bunch is input. When sending the test request information using the floppy disk, the floppy disk must be carried separately in addition to the sample and the request slip. Furthermore, since the quality control and cleansing of the inspection data can be used only by the method using the quality control sample, the previous value check method using the data of the subject sample cannot be used. Also, the inspection result report cannot be input to the computer unless the inspection center sends a floppy disk separately from the inspection result report.

The present invention has been made in view of the above problems. An object of the present invention is to save information input by exchanging information between a medical department and an inspection department by using a two-dimensional bar code. It is to realize the simplification and simplification, and to enable the previous value check in the accuracy control which has not been performed in the conventional inspection center.

[0013]

In order to achieve the above object, the method of requesting and reporting a sample test using a two-dimensional bar code according to the present invention is used in a hospital or clinic to examine patient attribute information and test history. If you have a file or database that records information and information, create an inspection request form to perform a sample inspection, collect the sample, send this inspection request form and the sample to the inspection department, and the inspection department requests the above-mentioned inspection. Performs sample registration, analysis, and quality control of test results based on the report, creates a test result report and reports it to the requester, and responds the test results described in the test result report to the above-mentioned subject In the method for requesting and reporting a sample test recorded in a file or a database that is stored in the database, the sample attribute information and the test history information are recorded when the sample is collected for the sample test of the sample. The above-mentioned subject attribute information and previous inspection value are read from a file or database, and the designation of the inspection item is read from the code book in which the two-dimensional barcode is printed, and the barcode is attached to the blood collection tube numbered in advance. The first step of reading the sample number from the label and printing the subject attribute information, the inspection item, and the previous value for each inspection item on the inspection request form using characters and a two-dimensional barcode, and the inspection request form Scan the two-dimensional barcode, select the inspection item of the sample, register the previous value of the inspection item and the sample number, use the previous value for the previous value check in the inspection accuracy management, A second step of printing the inspection result on the inspection result report by characters and a two-dimensional bar code, and reading the two-dimensional bar code of the inspection result report on a recording medium And a third of the step of recording the 査 results.

[0014]

That is, in the method of requesting and reporting a sample test using a two-dimensional bar code of the present invention, in the first step, when the sample collection is performed to perform the sample test of the subject, the sample test is performed. The above-mentioned subject attribute information and the previous inspection value are read from the file or database in which the individual attribute information and the inspection history information are recorded, and the designation of the inspection item is read from the code book in which the two-dimensional bar code is printed and serially numbered in advance. The sample number is read from the bar code label attached to the collected blood collection tube, and the subject attribute information, the inspection item, and the previous value for each inspection item are printed on the inspection request form as characters and a two-dimensional bar code. And in the second stroke,

The sequence of the method for requesting and reporting a sample test using a two-dimensional bar code according to the embodiment will be described in detail below with reference to the flowcharts of FIGS. 3 and 4. At the hospital / clinic that requests the examination, first, the subject attribute information and the previous examination data are read from the optical card carried by the subject (step S101), and the examination item for the day is selected from the barcode book. The state of the barcode book for selecting this item is as shown in FIG. 5 (step S102). Next, read the barcode indicating the sample container number attached to the sample container (test tube etc.) used for sample collection. The state of the sample container label is as shown in FIG. 6 (step S103).

Then, the inspection request source information is added to the above information, and the inspection request form is printed in characters, and the same information as the contents written in characters on the paper of the same request form is printed in a two-dimensional bar code. The inspection request form is as shown in FIG. 7, and the inspection request two-dimensional barcode information format is as shown in FIG. 8 (step S104). Further, the sample is collected in the sample container selected in step S103 (step S105), and the obtained sample and the inspection request form are sent to the inspection center (step S106).

Upon receipt of the sample and the test request form sent in this way, the test center receives steps S201 to S201.
The processing of 212 is performed. That is, when the inspection request form and the sample are received (step S201), the two-dimensional barcode of the inspection request form is read by the two-dimensional bar code reader, and the subject attribute information, the inspection request item, the previous inspection data, the sample container number, Input the inspection request source information into the inspection information system and create an inspection result file. This inspection result file is composed of a plurality of fixed length records, and the record format example of the inspection result file is as shown in FIG. 9 (step S202). At the reception stage, the area of the inspection value this time is blank indicating that the inspection has not been performed.

Next, in the inspection information system, a worksheet file is created for each analyzer to instruct which item should be analyzed for which sample. This worksheet file is composed of a plurality of fixed length records, and an example record format of the worksheet file is as shown in FIG. 10 (step S203).

On the other hand, the sample is subjected to pretreatment such as centrifugation and set in the analyzer (step S204).
Then, when the sample is set in the analyzer in step S204, the analysis work is started. Furthermore, the analyzer reads the bar code label of the sample container using the built-in bar code reader device, inquires of the inspection information system which item should be analyzed for that sample using the sample container number as a key, The analytical information system receives this inquiry. The format of the inspection item inquiry message format from the analyzer to the inspection information system is as shown in FIG. 11 (step S205). Then, the analysis information system searches the worksheet file using the sample container number of the inquiry as a key, transmits the analysis request item information of the sample to the analyzer, and the analyzer receiving the analysis request item information analyzes the item. Carry out. The format of the inspection item instruction message format from this inspection information system to the analyzer is as shown in FIG. 12 (step S
206).

Further, the analysis information system receives the analysis result information using the sample container number from the analyzer as a key,
Store in the inspection result file. The format of the test result report message format from this analyzer to the test information system is as shown in FIG. 13 (step S207). Then, the data including the previous value check method of comparing the previous value data recorded in the worksheet file with the present analysis data of the inspection result file is checked, and the accuracy control and cleaning of the data are performed (step S208). Further, this result is determined (step S209), and the sample for which the test result is determined to be NG is retested (step S210).

In this way, retesting and data cleansing are performed until the test results are judged to be valid for all the samples. Then, an inspection result report is printed on the inspection results that have been cleaned. The inspection result report is printed with characters and a two-dimensional bar code. An example of this inspection result report is as shown in FIG. 14, and an example of the inspection result report two-dimensional barcode information format is as shown in FIG. 15 (step S211).
Then, the inspection result report is sent back to the hospital or clinic that requested the inspection (step S212).

The hospital or clinic receiving this report reads the two-dimensional bar code and records the test result on the optical card of the subject (step S107). The method for requesting and reporting a sample test using a two-dimensional bar code according to an embodiment of the present invention has been described above. The two-dimensional bar code can encode a large amount of character information and can be easily read and written by a machine. Therefore, various other uses are possible.

For example, if a two-dimensional bar code is applied to a prescription for instructing the prescription of a drug and is used between a hospital / clinic and an out-of-hospital dispensing pharmacy, it is also useful for improving the efficiency of accounting processing and dispensing processing at the pharmacy. be able to. At this time, if the medication history information and the contraindicated drug information read from the optical card of the subject can be simultaneously converted into a two-dimensional bar code for reference, it is possible to contribute to the improvement of medical quality such as side effect reduction.

Although the optical card is taken as an example of the file or database of the subject information in the description of this embodiment, the present invention does not depend on the optical card as the file or database of the subject information. Of course, the present invention is also applicable to a database system constructed on an information recording medium such as an IC card or a computer hard disk device.
