Description

  The present invention relates to a document management server, a document management program, and a document management method for managing electronic documents.

  In recent years, when a paper document in which a document is written on a paper medium is stored electronically, the document description surface of the paper document is scanned (scanned) by an image reading device, and the scanned image (image) data is stored. Stored as an electronic document. In addition, the user can display the electronic document stored in this way on the monitor of the display terminal for browsing.

  When viewing an electronic document, the monitor that displays the electronic document is roughly matched to the size of the paper document, and one electronic document is displayed on one screen of the monitor, so that the same visibility as the original paper document is achieved. Can be secured. However, when there are a plurality of electronic documents to be browsed, the user has to replace the electronic documents on the monitor one by one and confirm the relationship between the plurality of electronic documents, for example, how the electronic documents were generated, It was difficult to comprehensively grasp the time flow.

  Therefore, among electronic documents such as word processors, a technique for temporarily deleting a margin area (edge) generated electronically in order to secure the edge of a printing surface and continuously displaying a document across a plurality of printing areas (For example, Patent Document 1).

Japanese Patent No. 3048332

  However, in the technique based on the character (text) data input through the operation unit described in Patent Document 1 and the like described above, only character data is stored as an electronic document, and data indicating blanks such as a blank area is not stored. When printing or displaying a print image, a blank space or the like is added for the first time. Therefore, the technique for deleting the blank area of Patent Document 1 described above merely cancels the addition of the blank area at the time of printing or display, and does not recognize the blank area in the electronic document. Therefore, when the electronic document is not character data but image data, the technique cannot be applied.

  For this reason, in order to grasp the relationship between a plurality of electronic documents in which image data is mixed, the user prints a plurality of digitized electronic documents, returns them to paper documents again, and then the entire relationship. Had confirmed.

  However, the amount to be confirmed in the form of a paper document is the same as that of an electronic document, and a remarkable improvement in viewability cannot be expected. On the contrary, since an electronic document with many blanks is printed in a blank state, it has resulted in a waste of resources. In addition, since the user cannot proceed to the completion of printing the electronic document, the time efficiency is also lowered. In addition, the work area is occupied to store paper documents that are no longer needed after browsing, space utilization efficiency is reduced, and the cost of discarding the paper documents is increasing due to privacy issues. It was.

  SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a document management server, a document management program, and a document management method capable of improving readability and effectively utilizing resources.

  In order to solve the above problems, a document management server of the present invention is held by a holding unit that holds an electronic document read from an object to be read, a determination unit that determines an unfilled area of the electronic document, and a holding unit. An electronic document extracting unit that extracts a plurality of electronic documents from the existing electronic documents, rearranges the extracted electronic documents in a predetermined order, and a plurality of electronic documents rearranged by the electronic document extracting unit. And an electronic document relocation unit that deletes the included non-filled areas and refills and re-fills the filled areas of these electronic documents when the unfilled areas determined by the determination unit are included. .

  As described above, a highly continuous electronic document that eliminates unnecessary unfilled areas of the read image by arranging the filled areas and rearranging the electronic documents while maintaining the order according to the presence or absence of the unfilled areas. Can be generated. In this way, the amount of information displayed on the monitor of the display terminal can be increased at a time, and the relationship between a plurality of electronic documents, for example, how the electronic documents were generated and their temporal flow can be comprehensively grasped. In addition, since a plurality of electronic documents can be compared simultaneously, a difference (change) in description contents can be quickly grasped. If the relationship between a plurality of electronic documents can be ascertained on the monitor in this way, the necessity for printing can be reduced, and costs related to resources, storage, disposal, etc. due to printing can be reduced and time efficiency can be improved. Furthermore, since the total amount of electronic documents to be browsed can be reduced, operability such as replacement of electronic documents can be improved.

  In the rearrangement of the entry area, the electronic document rearrangement unit may reduce the entry area by a reduction ratio within a predetermined range when the entry area is not accommodated in the document area of the electronic document.

  With such a configuration, it is possible to reduce the size of the entry area at a reduction rate within a predetermined range, and to reposition the entry area that cannot be originally packed, so the amount of information to be displayed on the monitor of the display terminal can be increased. Thus, it is possible to further improve the viewability.

  The electronic document rearrangement unit reduces the image of the entry area by applying an image reduction algorithm when the entry area is image data when the entry area is image data. Each character may be reduced by point conversion.

  Thus, the image data can be appropriately reduced by the image reduction algorithm. In addition, for character data, generally point converted fonts are prepared, so characters can be reduced with a lighter processing load than the image reduction algorithm, and it is possible to reduce the overall load and shorten the processing. Become.

  If the entry area in the selected electronic document is reduced based on the user input through the operation unit of the display terminal, the electronic document rearrangement unit returns the entry area to the size before reduction. It may be rearranged.

  With this configuration, after comprehensively grasping the relationship between a plurality of electronic documents through an electronic document with a reduced entry area, only the necessary entry area can be visually recognized in a normal size. The effect can be obtained in a balanced manner.

  The electronic document rearrangement unit may not execute the rearrangement to the unfilled area for the electronic document in which deletion of the unfilled area is not permitted.

  If the electronic document is, for example, a surgical consent form or a doctor entry field and modification is not permitted, the deletion of the unfilled area in the electronic document is prohibited, so that the original document is reproducible and the electronic document is trusted. Sex can be secured.

  The document management server may further include an index superimposing unit that superimposes index data indicating a break between electronic documents before rearrangement on the rearranged electronic document.

  As described above, the document management server rearranges the electronic documents while keeping the entry areas in order. However, if it is simply packed, it cannot be specified whether the entry area is described in the same electronic document or in a different electronic document. Here, by superimposing the index data on the delimiter positions between the electronic documents, the user can grasp in what unit the entry area is described in the electronic document.

  The electronic document rearrangement unit may not modify the electronic document held in the holding unit depending on the rearrangement of the electronic document.

  The electronic document rearrangement unit separately generates an electronic document from which an unfilled area is deleted for display or printing without modifying the electronic document in the holding unit. With this configuration, it is possible to improve the browsing property while reliably maintaining the originality of the electronic document. In addition, by prohibiting alteration (overwriting) of the electronic document, it is possible to protect the original electronic document from unauthorized tampering and erroneous processing.

  The determination unit may identify the entry area based on the presence or absence of colored pixels, and determine the unfilled area from the difference between the document area and the entry area.

  With this configuration, the determination unit can divide the document area into an entry area and an unfilled area easily and without omission, and the electronic document rearrangement unit can stably pack and rearrange the entry area. It becomes possible.

  The determination unit may subdivide the document area into one or a plurality of blocks and determine an unfilled area in units of the blocks.

  With this configuration, the determination unit can divide the document area into a filled area and a non-filled area uniformly and easily without omission, and the electronic document rearrangement unit can block the block with a uniform size. It becomes possible to stably refill the filling area in units.

  In order to solve the above problems, a document management program according to the present invention includes a computer that includes a determination unit that determines an unfilled area of an electronic document read from an object to be read, and an electronic document held by the holding unit. The electronic document extraction unit that extracts a plurality of electronic documents and rearranges the extracted electronic documents in a predetermined order, and the plurality of electronic documents that are rearranged by the electronic document extraction unit are determined by the determination unit. If an unfilled area is included, the included unfilled area is deleted, and the electronic document rearrangement unit functions to close and rearrange the filled areas of these electronic documents.

  In order to solve the above problems, a document management method of the present invention includes a step of determining an unfilled area of an electronic document read from a read object, and a plurality of electronic documents stored in a storage device. Included is a step of extracting an electronic document, rearranging the plurality of extracted electronic documents in a predetermined order, and a plurality of the rearranged electronic documents including a determined unfilled area. Deleting unfilled areas, and filling and relocating the filled areas of these electronic documents.

  The above-described components based on the technical concept of the document management server and the description thereof can be applied to the document management program and the document management method.

  As described above, according to the present invention, it is possible to improve viewability and effectively use resources.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The dimensions, materials, and other specific numerical values shown in the embodiments are merely examples for facilitating the understanding of the invention, and do not limit the present invention unless otherwise specified. In the present specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals, and redundant description is omitted, and elements not directly related to the present invention are not illustrated. To do.

  When a paper document is stored electronically, a document storage system that scans the paper document with an image reading apparatus and stores the scanned image data as an electronic document has been widely put into practical use. In addition, the user can display the electronic document stored in this way on the monitor of the display terminal for browsing. In this embodiment, a document management system for managing such an electronic document will be described in detail. However, in order to facilitate understanding, an electronic medical record used in a medical institution will be described as a specific example of the electronic document. To do. Here, the electronic document (electronic medical record) includes both scanned image data obtained by scanning a document described in a paper medical record, for example, a paper medical record, and character data input through an operation unit. Therefore, data corresponding to one paper chart is set as one electronic chart.

  In recent years, as medical charts used in medical institutions, due to the ease of management and the advantage of space occupancy, the introduction of electronic medical charts that fill in examination contents electronically without using paper media (paper medical charts) has been promoted. Yes. However, since the means of filling the contents of the examination in the electronic medical record is limited to input through a keyboard or dedicated keypad, it is not possible to fill in figures and symbols easily, and if possible, refer to it. It takes a certain amount of time to read out the graphics and symbols and display them on the monitor, which may delay the examination. In addition, since a conventional document management system using an electronic medical record requires enormous introduction costs, it still takes time to penetrate all medical institutions including small and medium hospitals. For this reason, the paper chart of paper media has been reviewed.

  Therefore, the document management system of the present embodiment aims to improve the viewability of the electronic medical record on the monitor and effectively use resources such as paper media while suppressing the introduction cost.

(Document Management System 100)
FIG. 1 is an explanatory diagram showing a schematic connection relationship of the document management system 100. The document management system 100 includes a document management server 110, an image reading device 120, a display terminal 130, and a printing machine 140, and manages electronic documents, particularly electronic medical records in medical institutions. Here, an example is given in which the document management server 110, the image reading device 120, the display terminal 130, and the printing machine 140 are formed separately, but the present invention is not limited to this, and two or more selected items are selected. These devices can also be formed integrally.

  The document management server 110 is connected to the image reading device 120, the display terminal 130, and the printing machine 140 through a communication network 102 such as a dedicated communication line, the Internet, and an intranet, and uses the image reading device 120, the display terminal 130, and the printing machine 140. Thus, the entire document management system 100 is managed. Detailed functions of the document management server 110 will be described later.

  The image reading device 120 is configured by a scanner, a network scanner, or the like, and receives the reflected light of the light irradiated on the document description surface of the object to be read (here, the paper chart), thereby displaying the described contents as an image. The data is read as data, and the read image data is transferred to the document management server 110. The transferred image data is stored in the document management server 110 as an electronic medical record.

  The display terminal 130 includes a monitor 132 and an operation unit 134, and is used mainly by a user such as a doctor to view an electronic document (here, an electronic medical record). The monitor 132 includes a liquid crystal display, an organic EL (Electro Luminescence) display, and the like, and displays an electronic medical record stored in the document management server 110. The operation unit 134 includes a keyboard provided with a plurality of operation keys, a pointing device such as a mouse, a cross key, a joystick, a touch panel installed on the display surface of the display 130, and the like, and receives a user's operation input.

  The printing machine 140 includes a printer, a network printer, and the like, and prints the electronic medical record stored in the document management server 110 on a paper medium. The paper chart printed on the paper medium is used for the user to refer to the examination contents or to add the examination contents. The printing machine 140 may be configured as a multifunction machine that is integrally formed with the image reading apparatus 120.

  In the document management system 100, first, a new paper chart 104 and a binder (not shown) are generated for a new patient. When the contents of the examination are written on the paper chart 104 by a user such as a doctor, the contents of the examination are read by the image reading device 120, and the paper chart 104 is stored in the chart chart 106. When the same patient comes to the hospital, the paper chart 104 is extracted from the chart chart 106 and distributed to the user (doctor or the like). At this time, the user can view the past examination contents and the like related to the target patient on the monitor 132 using the display terminal 130.

  In the document management system 100, the user can input the contents of the examination through the display terminal 130, or can enter it with a handwriting using the paper chart 104. Therefore, the user is not forced to input to the operation unit 134 of the display terminal 130, can face the patient or the like through the paper chart 104, and enter the examination contents on the paper chart 104 while observing the state of the patient. It becomes possible. In this way, the user can efficiently perform an appropriate medical examination without abrupt change of an existing medical examination form such as a paper chart. Hereinafter, the operation of the document management system 100 will be described while describing the specific configuration of the document management server 110.

(Document Management Server 110)
FIG. 2 is a functional block diagram showing the configuration of the document management server 110. The document management server 110 includes a holding unit 150, an interface unit 152, and a control unit 154.

The holding unit 150 includes RAM, EPROM (Erasable Programmable ROM), EEPROM (Electrically EPROM), flash memory, HDD (Hard disk drive), and the like, and holds various databases and tables, programs used in the control unit 154, and the like. To do. Further, in the present embodiment, the holding unit 150 includes a plurality of electronic medical records 210 that are read from the paper medical record 104 by the image reading device 120, document identification information 212 that is assigned to each electronic medical record 210, The area attribute information 214 is held. The document identification information 212 and the region attribute information 214 will be described in detail later.
Note that the holding unit 150 may be configured by a storage device provided outside the document management server 110, and may be configured by, for example, an external NAS (Network Attached Storage) or a shared disk.

  The interface unit 152 includes an external connection terminal such as a USB (Universal Serial Bus) port. For example, the image reading apparatus is connected through a communication medium such as a USB connection cable, Bluetooth (registered trademark), IEEE802.11b / a / g / n. 120, a mutual communication connection is established with the display terminal 130, the printer 140, and the like.

  The control unit 154 controls the entire document management server 110 by a semiconductor integrated circuit including a central processing unit (CPU), a ROM storing programs, a RAM as a work area, and the like. In addition, the control unit 154 performs a parameter processing unit 160, an electronic document generation unit 162, a determination unit 164, a document enhancement unit 166, an electronic document extraction unit 168, and an electronic document rearrangement unit 170 by program processing in cooperation with the semiconductor integrated circuit. , The index superimposing unit 172, the electronic document display unit 174, and the electronic document printing unit 176.

  The parameter setting unit 160 prints parameters related to the display terminal 130 when displaying the electronic medical record 210 on the display terminal 130 based on the user input through the operation unit 134 of the display terminal 130 and the electronic medical record 210 on the printing machine 140. Parameters related to the printing press 140 are set.

  Parameters relating to the display terminal 130 include the size of the display screen (for example, 20 inches), the number of pixels (for example, 1920 × 1080 dots), the display magnification of the electronic medical record 210 or the screen occupation ratio of the electronic medical record 210, and the reduction ratio of the image data. Allowable range (for example, 80% to 99%), character data point conversion rate allowable range (for example, 80% to 99%), and the like. Parameters relating to the printing machine 140 include a print target (for example, A4 size plain paper), a printing magnification of the electronic medical record 210 or a printing surface occupation ratio of the electronic medical record 210, an allowable range of a reduction ratio of image data, and points of character data. There is an allowable range of conversion rate.

  The electronic document generation unit 162 reads (scans) the document description surface of the paper chart 104 that is the object to be read through the image reading apparatus 120, and adds the document identification information 212 for identifying the other to generate the electronic medical chart 210. To do. In addition, when the patient for whom the electronic medical record 210 is generated corresponds to a new patient, the electronic document generation unit 162 also generates a binder for associating the medical record with the patient.

  As described above, the configuration in which the document identification information 212 is added when the paper chart 104 is read allows the paper chart 104 and the document identification information 212 to be compared with each other in a shorter time than when the document identification information is added later. In addition, the user can easily view the electronic medical record 210 using the document identification information 212 immediately after reading (in real time).

  As the document identification information 212, first, an incremented exclusive number is attached to the electronic medical record 210 in the order of generation. Further, the document identification information 212 includes storage destination information indicating a storage destination of the paper chart 104 in the chart chart 106, delivery destination information indicating a delivery destination of the paper chart 104, and a discard period indicating the disposal period of the paper chart 104. Information may be associated.

  For example, when a paper chart 104 stored for a certain period of time (for example, five years) is required to comply with legal obligations, the user refers to the storage destination information, so that the user can refer to the original paper chart 104. You can easily know where to store. Further, when entrusting storage of the paper chart 104 after the scan is completed to an external specialist or the like, the user efficiently delivers a large amount of the paper chart 104 by referring to the delivery destination information. be able to. Further, the user can easily and reliably manage the disposal deadline of the paper chart 104 stored in the chart chart 106 based on the disposal deadline information. For example, only the paper chart 104 in which the expiration of the disposal deadline has been notified. By making the object to be discarded, it becomes possible to strictly manage the storage of the chart storage 106.

  Further, as the document identification information 212, signature information (for example, a user ID or a seal image) specifying the creator of the paper chart 104 or the input person of the electronic chart 210, and the paper chart 104 are created or the electronic chart. Processing date / time information (for example, image reading time, image processing time, original management information setting time, signature information setting time, etc.) indicating the processing date / time when 210 is input may be associated. Thus, the user who created or modified the document image information can be specified, and the maintainability of data can be strictly managed.

  Further, the document identification information 212 includes information indicating whether or not the electronic medical record 210 allows deletion of an unfilled area described later. If deletion of the unfilled area is not permitted in the allowance / non-permission information, the rearrangement of the electronic medical record 210 to the unfilled area by the electronic document rearrangement unit 170 described later is not executed. If the electronic medical record 210 is, for example, a surgical consent form or a doctor entry field, and modification is not permitted, the electronic medical record 210 is prohibited from deleting an unfilled area, thereby maintaining the reproducibility of the original, The reliability of the chart 210 can be ensured.

  The determination unit 164 determines an unfilled area of the electronic medical record 210 generated by the electronic document generation unit 162. Here, the unfilled area refers to an area where a valid document is not filled in the document area, and an area where a valid document is filled is defined as an entry area. The document area refers to an area to be entered on the format, and other areas that are not to be entered are non-document areas. In the non-document area 220, document identification information 212 or the like is printed in advance, and subsequent information input such as a document is basically prohibited. In this embodiment, the determination unit 164 acquires the format information of the paper chart 104 by using a barcode or the like applied to the paper chart 104 in order to distinguish ruled lines or the like printed in advance on the paper chart 104 from the document. By taking the difference, only the post-entry document is extracted. Further, the determination unit 164 determines the presence / absence of a valid document based on, for example, the presence / absence of a pixel (colored pixel) having a color different from the color of the paper surface of the paper chart 104.

  When determining the unfilled area, the determination unit 164 determines the unfilled area from the difference between the document area and the filled area, or subdivides the document area of the electronic medical record 210 into one or a plurality of blocks. . Then, the determination unit 164 associates area attribute information 214 indicating which area the entry area and unfilled area are with. Here, the determination unit 164 determines an unfilled area with respect to the electronic medical record 210 generated by the electronic document generation unit 162, but the electronic document extraction unit 168 described later extracts not only this timing. An unfilled area may be determined afterwards for the electronic medical record 210.

  3 and 4 are explanatory diagrams for explaining the document area 218 in the electronic medical chart 210. FIG. As shown in FIG. 3A, the electronic medical record 210 is divided into a document area 218 that is a reading target of the image reading apparatus 120 and a non-document area 220 that is not a reading target. The determination unit 164 searches the document area 218 for colored pixels in the vertical direction, derives the upper limit and lower limit positions where the colored pixels exist, and the area between them is an entry area as shown in FIG. 226 is specified. Then, the determination unit 164 sets a difference area between the document area 218 and the entry area 226 as an unfilled area 228. Therefore, the size of the entry area 226 and the unfilled area 228 is equal to the width of the document area 218 in the horizontal direction of the electronic medical record 210 and has an arbitrary length in the vertical direction. Here, since the entry area 226 and the unfilled area 228 are simply divided depending on the presence or absence of colored pixels, the processing load can be reduced.

  With this configuration, the determination unit 164 can divide the document area 218 into the entry area 226 and the unfilled area 228 easily and without omission, and the electronic document rearrangement unit 170 described later stabilizes the entry area 226. It is possible to rearrange and rearrange.

  Further, as shown in FIG. 4, the determination unit 164 may subdivide the document area 218 into one or a plurality of blocks 222 and determine the unwritten area 228 in units of the blocks 222. The block 222 is obtained by dividing or equally dividing the document area 218 according to a predetermined rule, and is formed in a rectangular shape, for example. In FIG. 4A, the block 222 is formed to have a size equal to the width of the document area 218 in the horizontal direction of the electronic medical record 210 and equally divided into a predetermined number (eg, 4) of the document area 218 in the vertical direction. ing. The block 222 is determined in the order of (1), (2), and (3) from the top to the bottom of the document area 218. Further, as shown in FIG. 4B, the block 222 can be formed in the horizontal direction of the electronic medical record 210 in a size obtained by equally dividing the document area 218 by a predetermined number (for example, 2). The block 222 shown in FIG. 4B is arranged in the order of ((1), (2)) from the left to the right of the document area 218 ((2), (3)) from the top to the bottom. Determined. The determination unit 164 determines whether or not each of the subdivided blocks 222 includes a colored pixel. If included, the determination unit 164 sets the block 222 as an entry area 226. 228.

  With this configuration, the determination unit 164 can divide the document area 218 into the entry area 226 and the unfilled area 228 uniformly and easily without omission, and the electronic document rearrangement section 170 (to be described later) It is possible to stably fill and re-arrange the entry area 226 in units of blocks having the same size.

  Subsequently, the determination unit 164 associates the area attribute information 214 including information indicating whether the area corresponds to the entry area 226 or the unfilled area 228 with each area such as the entry area 226 and the unfilled area 228. . The entry area 226 is further attached with information indicating whether it is composed of image data or character data. Here, the image data refers to data for recognizing an image (image) by a plurality of pixel data read by the image reading device 120, and the character data is a character (text) input through the operation unit 134 of the display terminal 130 or the like. ). Moreover, even if it is the data read by the image reading apparatus 120, the data converted into the character through an optical character reader (OCR: Optical Character Reader) etc. can be handled as character data.

  Further, the determination unit 164 determines whether or not the entry area 226 is additionally written when the target electronic chart 210 is added to the electronic chart 210 generated at different times. Information indicating that the area 226 is the added entry area 226 is added to the area attribute information 214. For example, the determination unit 164 subdivides the read electronic medical record 210 to generate the block 222, and then generates each block 222 generated and each block 222 of the existing electronic medical record 210 stored in the holding unit 150. Compare and extract blocks with different descriptions. Then, the determination unit 164 adds information indicating that the entry area 226 is added to the different block 222.

  With this configuration, it is possible to easily identify the existing medical examination contents and the added medical examination contents in the electronic medical record 210, and the user can easily grasp the difference between the examination contents.

  The document emphasizing unit 166 uses, for example, Japanese Patent Application No. 2004-332940 (Japanese Patent Application Laid-Open No. 2006-148292) found by the present applicant for image data in the subdivided entry area 226, for example, as input image It is determined whether the data is a character, pattern, or background image area, and image processing is performed so that the edges are emphasized. According to such a technique, image processing is performed on the read at least one image data so that the edge is emphasized. Therefore, even after the paper chart 104 is repeatedly read by the image reading device 120 a plurality of times. Document image information can be provided with characters and images that can be read by the user.

  The electronic document extraction unit 168 extracts the electronic medical record 210 associated with one or more document identification information 212 specified based on the user input through the operation unit 134 of the display terminal 130, and extracts the extracted electronic medical record 210. Are rearranged in a predetermined order designated based on the user input.

  FIG. 5 is an explanatory diagram showing an example of a reference screen 230 that prompts extraction of the electronic medical record 210. The user can specify the electronic medical record 210 desired to be viewed through the reference screen 230 shown in FIG. First, the user inputs an identification number given exclusively for each patient in the patient number 232 of FIG. If the patient number 232 or the input described below is wrong, the clear button 234 can be used to return to the initial screen.

  In addition, the user can narrow down the display range of the electronic medical record 210 by the date range 236 and the medical record type 238. Then, as the display method, the item “by time” or “by type” of the classification 240 can be selected, and the check box 242 of “delete blank” characteristic in this embodiment can be checked at that time. Here, the item “by time” indicates that the electronic medical record 210 is displayed in chronological order, and the item “by type” indicates that it is displayed for each type of medical record. When the “delete blank” check box 242 is checked, deletion of the unfilled area 228 is executed in the electronic document rearrangement unit 170 described later. In addition, the user can further select, in each item of the selected category 240, a selection column 244 for “display new medical chart in front” or “display old medical chart in front” or a page to be opened first. By selecting the selection column 246, the arrangement order can be changed. Thus, after designating a specific display mode of the electronic medical record 210, the user can view the electronic medical record 210 by pressing the display start switch 248.

  Subsequently, the electronic document extracting unit 168 temporally displays “new medical chart in front” or “old medical chart in front” in each item of “by time” or “by type” selected as the classification 240. The electronic medical records 210 are rearranged in the arrangement order selected in the “Yes” selection field 244.

  6 and 7 are explanatory diagrams for explaining the rearrangement operation of the electronic document extraction unit 168. FIG. Assume that the electronic document extraction unit 168 extracts a plurality of electronic medical records 210 as shown in FIG. 6A associated with the document identification information 212. Here, the numerical value located in the upper part 250 of the electronic medical record 210 is the date when the electronic medical record 210 was created, and the alphabet located in the lower part 252 is the type of the electronic medical record 210 (for example, A = transition record, B = gastroscope) , C = electrocardiogram, D = bacteria test). Here, it is assumed that A of the types of the electronic medical record 210 can delete the unwritten area 228, but deletion of B, C, and D is not permitted.

  For example, “all (all types)” is selected as the chart type 238, “by time” is selected as the classification 240, “display old chart in front” is selected in the selection field 244, and an index is assigned in advance. If the setting is made, as shown in FIG. 6B, the electronic medical chart 210 is rearranged so that the electronic medical chart 210 is in time series and in ascending order in time. At this time, since an index is set, the creation month 254 of the electronic chart 210 to be displayed next is shown as an index at the change of the month based on the date when the electronic chart 210 was created.

  Further, when the electronic document extraction unit 168 extracts a plurality of electronic medical records 210 as shown in FIG. 7A as in FIG. 6A, “all” is selected as the medical record type 238 and “ When “by type” is selected, “display old medical chart in front” is selected in the selection field 244, and an index is set in advance, as shown in FIG. The electronic medical record 210 is rearranged so as to be in ascending order for each type and in time. Also at this time, since the index is set, the type 256 to be displayed next is displayed as an index on the boundary of different types based on the type of the electronic medical record 210.

  The electronic document rearrangement unit 170 checks the “delete blank” check box 242 on the reference screen 230 described with reference to FIG. 5 and adds an arbitrary electronic medical record 210 in the rearranged electronic medical chart 210. When the unfilled area 228 determined by the determination unit 164 is included, the unfilled area 228 is deleted, and these electronic document entry areas (the next entry area of the same electronic medical record 210 and the subsequent electronic medical records) are deleted. 210 entry areas) are sequentially packed and rearranged. Here, “packing” means that the next non-filled area 228 is overwritten on the non-filled area 228 until all the non-filled areas 228 in the rearranged electronic medical record 210 are eliminated. Only the entire electronic medical record 210 is shortened.

  8 and 9 are explanatory diagrams for explaining the operation of the electronic document rearrangement unit 170. FIG. For example, as shown in FIG. 8, there are two electronic medical records 210a and 210b, and the electronic document extraction unit 168 rearranges them in the order of the electronic medical records 210a and 210b (the old medical chart is displayed in front). Here, the electronic document rearrangement unit 170 refers to the region attribute information 214 regarding all the regions in the document region 218 of the electronic medical record 210a whose display order is young, and whether or not an unfilled region 228 exists in the electronic medical record 210a. Judge. When the unfilled area 228 exists in the electronic medical record 210a, the electronic document rearrangement unit 170 deletes the unfilled area 228, and sequentially fills the filled area 226b of the next and subsequent electronic medical records 210b after the filled area 226a. Rearrange. In this way, the combined electronic medical chart 210c is generated.

  Here, as the non-document area 220c of the electronic medical chart 210c, the non-document area 220a of the first electronic medical chart (here, the electronic medical chart 210a) of the plurality of electronic medical charts 210 to be combined is used, and an electronic having only a combined entry area. The non-document area 220b of the medical chart (here, the electronic medical chart 210b) is deleted. Therefore, in the non-document area 220c of the combined electronic medical record 210c, only information such as the patient name and the patient number common to the combined electronic medical record 210 is displayed, and individual medical record IDs and barcodes are deleted. .

  In FIG. 8, the case where the unfilled area 228 is at the end (lower end) of the electronic medical record 210 has been described. However, when the unfilled area 228 is not at the end of the electronic medical record 210, that is, near the center of the electronic medical record 210. If there is, the electronic document rearrangement unit 170 deletes the unfilled area 228, fills the next entry area 226 in the same electronic medical record 210, and then sequentially fills the entry areas 226 of the electronic medical record 210 in the following order. Rearrange.

  Here, as shown in FIG. 4B, when there is an unfilled area 228 in the two-dimensional entry area 226 that is also divided in the horizontal direction of the screen, the electronic document rearrangement unit 170 maintains the arrangement order, The entry area 226 of the electronic medical record 210 is rearranged in the order shown in FIG.

  Also, as shown in FIG. 7B, the electronic medical record 210 rearranged by the electronic document extraction unit 168 in ascending order for each type is not filled in by the electronic document rearrangement unit 170 The area 228 is deleted, and the entire amount is reduced as shown in FIG. However, if the index is set to be assigned, it is assumed that rearrangement across the index type 256 is not performed. Further, regarding the types B, C, and D of the electronic medical record 210, deletion of the unfilled area 228 is not allowed, so that the electronic medical record 210 is not modified as will be described later.

  In this way, it is possible to grasp the state of entry of the electronic medical record 210 in units of areas, and the arrangement of refilling the electronic medical record 210 by filling the entry area 226 while maintaining the order according to the presence or absence of the unfilled area 228 eliminates the need for the read image. Therefore, it is possible to generate a highly continuous electronic medical record 210 that eliminates a blank area.

  Further, when the electronic medical record 210 having increased continuity as described above is displayed on the monitor 132 of the display terminal 130, the amount of information that can be displayed at a time increases, so a relationship between a plurality of electronic medical records 210, for example, the electronic medical record 210 is generated. It is possible to comprehensively grasp the background and time flow of the information, display it with high affinity with the user's thought process, and can simultaneously compare a plurality of electronic medical records 210. It becomes possible to quickly grasp the difference (change) in content.

  Furthermore, if the relationship between the plurality of electronic medical charts 210 can be grasped on the monitor 132, the need for printing is reduced, and effective use of resources relating to the printed matter that was originally printed, storage of the paper medical chart 104, disposal of the paper medical chart 104, and the like. Cost reduction and time efficiency can be improved. Furthermore, since the entire amount of the electronic medical record 210 to be viewed can be reduced, it is possible to improve operability such as replacement of the electronic medical record 210.

  By the way, even if the unwritten area 228 exists, the electronic document rearrangement unit 170 fills the unwritten area 228 because the size of the next filled area 226 to be packed in the unwritten area 228 is too large. If it is determined that the electronic chart 210 is deleted, the unfilled area 228 is deleted and no connection is performed. Therefore, when the entry area 226 is not accommodated in the document area 218 of the electronic medical record 210 in the rearrangement of the entry area 226, the electronic document rearrangement unit 170 reduces the entry area 226 at a reduction ratio within a predetermined range.

  FIG. 10 is an explanatory diagram showing a reduction operation by the electronic document rearrangement unit 170. Here, as in FIG. 8, an attempt is made to fill the unwritten area 228 of the electronic medical record 210 a with the filled area 226 d of the electronic medical record 210 d, but the filled area 226 d is larger than the unfilled area 228, and cannot be filled as it is. Accordingly, the electronic document rearrangement unit 170 reduces the entry area 226d by a reduction ratio within a predetermined range (80% to 100%), for example, 90%, and reduces the reduced entry area 226d ′ to the unfilled area of the electronic medical record 210a. Reposition to 228. In this way, the combined electronic medical chart 210e is generated.

  With such a configuration, the entry area 226 that cannot be originally packed can be packed and rearranged simply by reducing the entry area 226 at a reduction rate within a predetermined range, so that information displayed on the monitor 132 of the display terminal 130 at a time can be displayed. By increasing the amount, it becomes possible to further improve the viewability.

  When the area attribute information 214 includes information indicating whether the area attribute information 214 is composed of image data or character data, the electronic document rearrangement unit 170 stores the area attribute information 214 in the area attribute information 214 when reducing the entry area 226. Based on this, if the entry area 226 is image data, the image in the entry area 226 is reduced to, for example, 90% by applying an image reduction algorithm. If the entry area 226 is character data, the image in the entry area 226 is reduced. Each character is converted to points, for example, reduced from 12 points to 10.5 points.

  Thus, the image data can be appropriately reduced by the image reduction algorithm. In addition, for character data, generally point converted fonts are prepared, so characters can be reduced with a lighter processing load than the image reduction algorithm, and it is possible to reduce the overall load and shorten the processing. Become.

  Further, the electronic document rearrangement unit 170 sets the size before the reduction if the entry area 226 in the electronic medical record 210 selected by clicking or the like through the operation unit 134 of the display terminal 130 is reduced in advance. The entry area 226 is rearranged. For example, when the entry area 226d 'of the combined electronic medical chart 210e in FIG. 10 is clicked, the entry area 226d returns to the original size, and the electronic medical chart 210e is separated again into the electronic medical chart 210a and the electronic medical chart 210d.

  With this configuration, after comprehensively grasping the relationship between the plurality of electronic medical records 210 through the electronic medical record 210 in which the entry area 226 is reduced, only the necessary entry area 226 can be visually recognized in a normal size, and is easy to view. It is possible to obtain a balance between the effects of visibility and visibility.

  Here, the configuration has been described in which the electronic document rearrangement unit 170 reduces the entry area 226 and restores the original size. However, the present invention is not limited to this, and the entry area 226 is enlarged and rearranged. You can also click to see the original size.

  Furthermore, when the document identification information 212 includes information indicating whether or not the electronic medical record 210 allows deletion of the unfilled area 228, the electronic document relocation unit 170 determines whether or not the document identification information 212 is based on the document identification information 212. For the electronic medical record 210 in which deletion of the unwritten area 228 is not allowed, relocation to the unwritten area 228 may not be executed. For example, as described with reference to FIG. 9, A (progress record) can delete the unfilled area 228 depending on the examination date and type, but other B (gastrocamera), C (electrocardiogram) , D (bacteria test), the unwritten area 228 is not deleted.

  In the case where the electronic medical record 210 is not permitted to be modified due to, for example, a surgical consent form or a doctor entry field in addition to the above-described B (gastrocamera), C (electrocardiogram), and D (bacteria test), regarding the electronic medical record 210 By prohibiting deletion of the unfilled area 228, the reproducibility of the original can be maintained and the reliability of the electronic medical chart 210 can be ensured.

  Further, the electronic document rearrangement unit 170 does not modify (overwrite) the electronic medical record 210 held in the holding unit 150 when the electronic medical record 210 is rearranged. Therefore, the one or more electronic medical records 210 rearranged by the electronic document rearrangement unit 170 are used only for display or printing, or are stored in the holding unit 150 as data different from the original.

  With this configuration, it is possible to improve the viewability while reliably maintaining the originality including the blank portion (unfilled area 228) of the electronic medical record 210. Further, by prohibiting alteration of the electronic medical record 210, it is possible to protect the original electronic medical record 210 from unauthorized tampering and erroneous processing.

  Furthermore, when information indicating that the entry area 226 is added to the area attribute information 214 is added to the area attribute information 214, the electronic document rearrangement unit 170 stores the past electronic medical record 210 other than the entry area 226. It is possible to delete the entry area 226 that overlaps with. With such a configuration, it is possible to combine the entry areas 226 described in duplicate in the plurality of electronic medical records 210 into one, and further improve the browsing property.

  The index superimposing unit 172 superimposes index data indicating a break between the electronic medical records 210 before rearrangement on the rearranged electronic medical chart 210. Here, the index data is, for example, ruled lines (boundary lines) and symbols (marks) that cross the document area 218.

  As described above, the document management server 110 rearranges the electronic medical record 210 by filling the entry area 226 while maintaining the order. However, if the entry area 226 is simply filled, it cannot be specified whether the entry area 226 is written in the same electronic chart 210 or different electronic chart 210. Here, by superimposing the index data on the separation positions between the electronic medical records 210, the user can grasp in what units the entry area 226 is described in the electronic medical records 210.

  The electronic document display unit 174 displays the electronic medical chart 210 rearranged by the electronic document rearrangement unit 170 on the display terminal 130 if the “delete blank” check box 242 on the reference screen 230 is checked. If not checked, the original electronic medical record before the rearrangement is displayed on the display terminal 130. At this time, the electronic document display unit 174 can also display a parameter for identifying the electronic medical record 210 in the document identification information 212 on the screen as an OSD (On Screen Display).

  Further, when the rearranged electronic medical record 210 to be displayed is not accommodated in the display area of the monitor 132, the electronic document display unit 174 further reduces the entry area 226 at a predetermined reduction rate, and the entire electronic medical record 210 is monitored 132. May be accommodated.

  In the present embodiment, an example in which the electronic medical record 210 is rearranged at a time by the electronic document rearrangement unit 170 has been described. However, only the electronic medical record 210 for one screen is rearranged and displayed on the display terminal 130, and the operation unit The rearrangement relating to the next electronic medical chart 210 can be performed only after an instruction to view the next page of the image is given based on the user input through 134. This makes it possible to distribute the processing load.

  The electronic document printing unit 176 causes the printing machine 140 to print the electronic medical record 210 rearranged in accordance with a printing instruction based on a user input through the operation unit 134 of the display terminal 130. The electronic document printing unit 176 functions in the same manner as the electronic document display unit 174 except that the resultant product is a printed material. Therefore, the electronic medical record 210 rearranged by the electronic document rearrangement unit 170 can be printed in the same manner as the display on the monitor 132 by the electronic document display unit 174.

  In this way, by increasing the amount of information to be printed on the printed matter at once, the relationship between a plurality of electronic medical records 210, for example, how the electronic medical records 210 were generated and their temporal flow can be comprehensively grasped. Since a plurality of electronic medical records 210 can be compared at the same time, it becomes possible to quickly grasp the difference (change) in the description contents. Since the blank area (blank area) is deleted in this manner, resources can be effectively used by printing, and costs related to storage and disposal can be reduced and time efficiency can be improved. Further, the printing time can be shortened by reducing the printing amount, and the time efficiency can be improved.

  As described above, the document management server 110 described above can improve the viewability on the monitor 132 and can effectively use resources. Further, a document management program for causing a computer to function as the document management server 110, a computer-readable flexible disk, magneto-optical disk, ROM, EPROM, EEPROM, CD (Compact Disc), DVD (which stores the document management program) Storage media such as Digital Versatile Disk) and BD (Blu-ray Disc) are also provided. Here, the program refers to a data processing method described in an arbitrary language or description method.

  The document management program may be stored in an arbitrary application program server connected to the document management server 110 via the communication network 102, and may be downloaded in whole or in part as necessary. .

(Document management method)
Next, a document management method for managing documents using the document management server 110 described above will be described. 11 and 12 are flowcharts showing the overall flow of the document management method.

  In the document management server 110 in which parameters relating to the display terminal 130 and the printing press 140 are set by the parameter setting unit 160, the electronic document generation unit 162 first reads the paper chart 104 through the image reading device 120 (S300), and other papers. The electronic medical record 210 is generated with the document identification information 212 for identifying the medical record 104 (S302).

  Then, the determination unit 164 subdivides the document area 218 of the read electronic medical record 210 into one or a plurality of blocks 222 (S304), and determines whether or not the subdivided blocks 222 correspond to the unwritten area 228. The blank area 228 is replaced with the blank area 226, and the area attribute information 214 is associated (S306). The document emphasizing unit 166 performs image processing so that edges of the image data in the subdivided entry area 226, particularly image data, are emphasized (S308), and holds the electronic medical record 210 in the holding unit 150 (S310). .

  When browsing of the electronic medical record 210 is instructed through the operation unit 134 of the display terminal 130, the electronic document extraction unit 168, as shown in FIG. 12, displays one or a plurality of document identification information 212 specified based on user input. Are extracted (S312), and the extracted one or more electronic medical records 210 are rearranged in a predetermined order (S314).

  The electronic document rearrangement unit 170 sequentially extracts one electronic medical record 210 from the rearranged electronic medical records 210 (S316), determines whether or not an unfilled area 228 is included therein (S318), If the unfilled area 228 is included (YES in S318), whether or not the next filled area 226 of the same electronic medical record 210 or the filled area 226 of the subsequent electronic medical records 210 is accommodated in the unfilled area 228. (S320). Here, if it is determined that it can be accommodated in the unfilled area 228 (YES in S320), the electronic document rearrangement unit 170 deletes the unfilled area 228, and the next filled area 226 and The entry areas 226 of the electronic medical records 210 from the next order are sequentially packed and rearranged (S322).

  In addition, when it is not accommodated in the unfilled area 228 (NO in S320), the next entry area 226 of the same electronic medical record 210 or the subsequent entry area 226 of the electronic medical record 210 is reduced at a reduction ratio within a predetermined range. Thus, the electronic document rearrangement unit 170 deletes the unwritten area 228 and determines whether it can be stored in the unfilled area 228 (S324). The next entry area 226 or the entry area 226 of the electronic medical record 210 after the next order is reduced (S326), and is sequentially packed and rearranged (S322).

  On the other hand, if it is determined that the entry area 226 cannot be accommodated even if the entry area 226 is reduced (NO in S324), or if it is determined that the unfilled area 228 is not included (NO in S318), the electronic document rearrangement unit 170 The rearrangement relating to the electronic medical record 210 is not performed. Then, it is determined whether or not the processing has been performed on all the electronic medical records 210 extracted by the electronic document extraction unit 168 (S328). If all the processes are not completed (NO in S328), an unwritten area If the extraction process (S316) is repeated and all the processes are completed (YES in S328), the index superimposing unit 172 superimposes index data indicating the separation on the rearranged electronic medical record 210 (S330), The electronic document display unit 174 displays the rearranged electronic medical record 210 on the display terminal 130 (S332).

  When printing of the electronic medical record 210 is instructed based on user input through the operation unit 134 of the display terminal 130 (YES in S334), the electronic document printing unit 176 issues a print instruction through the operation unit of the display terminal. Accordingly, the electronic medical chart 210 rearranged on the printing press is printed (S336).

  Also with this document management method, it is possible to improve the viewability on the monitor 132 and to effectively use resources.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to this embodiment. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Is done.

  For example, in the above-described embodiment, the document management system 100 is configured by the document management server 110, the image reading device 120, the display terminal 130, and the printing machine 140, and functional units are arranged in each, but the configuration is not limited thereto. In addition, the present embodiment includes a case where all or a part of the functional units are distributed in each device or a plurality of functional units are integrated.
