Is.

  For example, the medical record content information print request information input at the electronic medical record creation terminal 2 prints only a specific part of a specific patient's medical record content information registered in the medical record content information database 22 or a specific date. , Only a specific part of the patient specified according to the request or a specific date is extracted from the medical record content information database 22 as information for printing.

  The printing chart management information extraction processing unit 10 includes electronic chart management information necessary for managing the electronic chart acquired by the electronic chart creation terminal 2 based on the chart content information print request information acquired by the electronic chart creation terminal 2. Processing for extracting electronic medical chart management information from the medical chart management information database 23 is performed.

  The electronic medical record management information extracted from the medical record management information database 23 is printed together with the medical record content information extracted from the medical record content information database 22 by the processing operation performed by the printing medical record content information extraction processing unit 9 as will be described later. The chart 4 is printed by the printer 4 by the processing operation of the section 12, and the chart is used to refer to the information stored in the chart management information database 23 so that who, when, who, and for what purpose It is possible to keep track of printed paper charts by grasping whether it has been issued, etc., and preventing unauthorized use and unauthorized use of charts. Therefore, information that enables this, for example, management information necessary for management of the electronic medical record stored in the medical record management information database 23 is extracted as including log serial numbers (unique). . For example, if the log serial number is extracted as management information, by using this, the information remaining in the medical record management information database 23 is referred to, and who, when, You can know whether a medical record was issued for the purpose.

  The copy-forgery-inhibited pattern information conversion processing unit 11 converts the electronic medical record management information extracted from the medical record management information database 23 by the printing chart management information extraction processing unit 10 into the copy-forgery-inhibited pattern character information to be printed by the printer 4 as described above. Is what you do.

  The electronic medical record management information extracted from the medical record management information database 23 is converted into copy-forgery-inhibited pattern character information by converting the medical record content information and the electronic medical record management information to the printer by the processing operation of the print processing unit 12 described later. When printed in step 4, the printed copy-forgery-inhibited pattern character information cannot immediately grasp the contents of the management information of the electronic medical record, and for the third party, simply the background of the printed medical record content information. This is because it is recognized that there is only a printed pattern (a simple enumeration of numbers, a combination of simple numbers and letters, a simple figure, a simple pattern, etc.) as a background pattern.

  The conversion to the copy-forgery-inhibited pattern character information performed by the copy-forgery-inhibited pattern information conversion processing unit 11 is performed in the form known in this technical field as long as the management information of the electronic medical record as exemplified above is converted into copy-forgery-inhibited pattern character information. Can be used. For example, the “serial number” (sequential number of log (unique)) in the management information of the electronic medical record is a simple pattern of numbers for a third party, a number that does not make sense for a third party, It is possible to adopt a form of conversion into a tint block that is only a combination of characters, figures, patterns, and the like. Further, although the copy-forgery-inhibited pattern character information as described above cannot be recognized and grasped, when copying (copying), conversion processing can be performed in a form that appears in a copy.

  In this way, the tint block information conversion processing unit 11 converts the tint block character information into the tint block character information. By the processing operation of the print processing unit 12 described later, the tint block character information superimposed on the chart content information and printed on the paper by the printer 4 is converted into the tint block character information. The management information (e.g., “serial number” (log serial number (unique)) etc. before the electronic medical record is grasped, and the information stored in the medical record management information database 23 is referred to using this information Thus, it is possible to grasp who, when and to whom, the chart was issued for what purpose, etc., and to trace the printed paper chart. As a result, it is possible to suppress unauthorized outflow and unauthorized use of medical records.

  The print processing unit 12 converts the medical record contents acquired from the medical chart content information extraction processing unit 9 from the medical record content information database 22 acquired by the electronic medical record creation terminal 2 and the ground pattern information by the ground pattern information conversion processing unit 11. The information specifying the printer 4 for printing the management information of the electronic medical record is a predetermined printer (that is, the printer capable of printing the management information of the electronic medical record converted to the copy-forgery-inhibited pattern character information on the paper so as to overlap the medical record contents) In the case of a predetermined printer, the chart contents extracted from the chart contents information database 22 by the printing chart contents information extraction processing unit 9 and the copy-forgery-inhibited pattern information converted by the copy-forgery-inhibited pattern information conversion processing unit 9 The management information of the converted electronic medical record is superposed on the designated printer 4 for printing.

  It should be noted that the printer provided in the electronic medical record management system of the present invention is converted to the medical chart contents extracted from the medical chart contents information database by the medical chart contents information extraction processing section and the ground pattern information converted by the ground pattern information conversion processing section. When the electronic medical record management information is received, the print processing unit automatically prints the medical record contents and the electronic medical record management information converted into the copy-forgery-inhibited pattern information. Does not need to perform the determination process in the above. Therefore, in that case, instead of the print processing section, the chart contents extracted from the chart contents information database by the printing chart contents information extraction processing section, and the ground pattern information converted by the ground pattern information conversion processing section. A processing operation unit of a computer that performs a function of causing a printer to execute a process of superimposing printing on the management information of the electronic medical record can be employed as the print processing unit.

  In the electronic medical record management system 1 of the present invention described above, the copy-forgery-inhibited pattern information conversion processing unit 11 further transfers the management information of the electronic medical record extracted from the medical record management information database 22 by the printing medical record management information extraction processing unit 10 to the printer 4. In this case, it is possible to use a tint block information conversion processing unit that performs conversion to encrypted tint block character information when converting to tint block character information to be printed.

  The encryption means is not particularly limited, and a publicly known one can be used. For example, the chart management information is encrypted with the encryption key, and the background pattern printed on the leaked chart is combined with the encryption key. By doing so, it is possible to make the chart management information displayed as a tint block display readable.

  Hereinafter, an example of a process of printing the electronic medical record management information converted into the copy-forgery-inhibited pattern information and the medical record contents on the paper in the electronic medical record management system 1 of the present invention will be described with reference to FIG.

  The operator accesses the electronic medical record management server 3 from the electronic medical record creation terminal 2 (step 301), and inputs information necessary for personal authentication from the electronic medical record creation terminal 2 in accordance with the location prompted by the operator authentication processing unit 6 (step 301). 302).

  The operator authentication processing unit 6 refers to the information registered in the operator authentication database 21 and authenticates the person who is operating the electronic medical record creation terminal 2 from the information input at the electronic medical record creation terminal 2 (step) 303).

  Only those authorized by the authentication of the operator authentication processing unit 6 can print the electronic medical record.

  Next, according to the prompt from the electronic medical record management information management processing unit 8, the operator who has received the authentication specifies electronic medical record management information (for example, a patient) necessary for managing the electronic medical record at the electronic medical record creation terminal 2. When the patient name, patient name, patient number, printing purpose, delivery date, delivery person, recipient, receipt method, etc.) are entered, the electronic medical record management information management processing unit 8 stores the information in the medical chart management information database 23. (Step 304). At this time, information on the authentication type (fingerprint, signature, etc.) in the authentication procedure is extracted from the operator authentication database 21 and registered in the medical record management information database 23 together with the information acquired from the electronic medical record creation terminal 2. The electronic medical record management information management processing unit 8 may perform the processing to be performed.

  Here, in response to the input of the medical chart content information print request information at the electronic medical chart creation terminal 2 as described above, the printing medical chart management information extraction processing unit 10 registers in the medical chart management information database 23 at the step 304. The management process of extracting the electronic medical chart management information including the electronic medical chart management information necessary for the management of the electronic medical chart acquired from the electronic medical chart creation terminal 2 is performed from the medical chart management information database 23 (step 306).

  The electronic medical record management information extracted from the medical record management information database 23 is printed together with the medical record content information extracted from the medical record content information database 22 by the processing operation performed by the printing medical record content information extraction processing unit 9. The chart is printed by the printer 4 by the processing operation of the above, and by using the information stored in the chart management information database 23 by using it, who issued the chart for what purpose to whom and for what purpose Can be traced, and the printed paper chart can be traced, and the role of suppressing the illegal outflow and unauthorized use of the chart is, for example, the electronic chart stored in the chart management information database 23. The serial number (unique) of the log is extracted from the management information necessary for management.

  When the above-described processing is performed by the printing chart management information extraction processing unit 10 in this way, subsequently, the background pattern information conversion processing unit 11 extracts from the chart management information database 23 by the printing chart management information extraction processing unit 10. The electronic medical record management information is converted into copy-forgery-inhibited pattern character information to be printed by the printer 4 (step 307).

  Next, according to the prompt from the print processing unit 12, the operator who has received the authentication uses the electronic medical record creation terminal 2 to extract the medical record extracted from the medical record content information database 22 by the printing medical record content information extraction processing unit 9. When information specifying the printer 4 for printing the contents and the management information of the electronic medical record converted into the copy-forgery-inhibited pattern information by the copy-forgery-inhibited pattern information conversion processing unit 11 is input, the print processing unit 12 determines that the printer specified by the information is a predetermined printer. It is determined whether or not the printer (i.e., the printer that can print the management information of the electronic medical record converted into the copy-forgery-inhibited pattern information on the paper superimposed on the contents of the medical record) (step 308).

  Then, in the case of a predetermined printer, the medical record content extracted from the medical record content information database 22 by the printing medical record content information extraction processing unit 9 and the management information of the electronic medical record converted into the ground pattern character information by the ground pattern information conversion processing unit 11 And the process of printing with the designated printer 4 is executed (step 309).
