Description

  The present invention relates to a handwritten electronic information recording system for converting handwritten electronic information recorded and stored in a storage device into a typeface information by designating a character recognizable part from an input device and displaying it on the screen while facilitating a phrase search. It is about. Hereinafter, as an example of the handwritten electronic information recording system, a handwritten electronic medical record system that processes a handwritten medical record recorded with electronic information in the medical field will be described in detail.

  Traditionally, in medical practice, there is a medical record that records a patient's medical condition and progress in chronological order.

  Since this medical record uses “paper” as the recording medium, it is natural that “handwriting” is the basis. If necessary, drawings, graphs, or medical data related to medical care such as standard drawings such as the lungs and heart It is possible to perform highly visual management such as pasting a printed matter on which is printed, attaching a tag to the described paper, and storing it in a color-specific file. Moreover, it is easy to look through the contents of the chart, and the chart made of “paper” is very flexible.

  However, there is a problem with this “paper” chart. That is, it is not easy to secure a storage location. Medical records are required to be kept for 5 years by the Medical Law. However, it is necessary to refer to the case, and corrections to the medical information recorded in this medical record are also obliged to leave a record of the correction and to leave the information before correction, and the amount of information tends to increase. .

  In this way, in addition to the duty to preserve medical charts, there is a problem in that the storage location becomes tight due to the mixing of “large numbers” of medical records such as long-term inpatients and long-term outpatients, and there is a problem of securing additional storage locations. It was. Naturally, when this "paper" medical chart is used, it is costly, and it also takes time to find a desired medical chart.

  Therefore, with the recent development of computerization technology, an electronic information recording system using an information processing device has been introduced as a means for storing medical contents so that they can be referred to and modified at any time.

  This system is an electronic version of the conventional “paper” medical chart. In April 1999, the Ministry of Health and Welfare sent a notice to each national medical institution that the electronic medical chart was approved as an official medical record. At the outset, it is rapidly spreading in current medical settings.

  By digitizing medical charts in this way, storage and management are unified and shared, and keyword search for large amounts of data is possible. In addition, storing information by means of paper charts related to medical practice requires an enormous cost and space, and these problems are also improved.

  On the other hand, however, there are new problems caused by digitization. In other words, a conventional electronic information recording system is composed of an arithmetic / control device, an input device consisting of a keyboard and a mouse, and an output device consisting of a display screen and a printer. This is a heavy burden.

  The doctor concentrates on the difficult input operation, and as a result, the thinking about the medical treatment is interrupted and the keyboard and mouse etc. are desperately operated in front of the patient. The patient may be worried about whether he / she is really worried about his / her physical condition.

  Therefore, in order to reduce the burden of inputting medical information, a method has been devised that uses a “pen tablet” as an input device that can be input as if it were recorded on a paper medium.

  As a system using this pen tablet, for example, there is an electronic medical chart recording apparatus and method disclosed in Japanese Patent Laid-Open No. 2000-325314 (hereinafter referred to as Patent Document 1).

  This device is based on a screen on which content determined in a limited area is displayed, and uses a liquid crystal pen tablet to input data by an operation by menu or button selection.

  That is, the operator selects items from the menu and buttons on the screen one after another and inputs data while viewing the screen displayed on the output device. In addition, input such as comments that cannot be selected from the items is input with a keyboard or drawn with a pen in a predetermined frame as disclosed in the drawing of Patent Document 1, character recognition is performed, and converted to character data And then enter.

  Therefore, in such a device, it is necessary to grasp complicated specifications such as menus and buttons, and there is a risk that the hospital side may take a second step in introducing the device. Since it is not possible to input what has been thought of instantaneously, thinking may be interrupted by an input operation, which may hinder diagnosis. Input items are determined in advance, and there are restrictions on the items to be input. Further, in order to refer to the past medical charts, the screens must be switched and displayed, and it is not possible to perform an input operation while viewing the past medical charts.

  Furthermore, when character recognition is performed, characters must be input within a predetermined frame, so that handwritten characters written at free positions cannot be recognized. Moreover, since character recognition needs to be performed by inputting into a handwritten character input sheet in order to perform character recognition, the input handwritten character cannot be recognized later.

  As a system that solves these problems, for example, there is an electronic information recording system disclosed in Japanese Patent Laid-Open No. 2003-225209 (hereinafter, Patent Document 2).

  This system provides a user-friendly electronic information recording system that enables free writing input using a pen-type input device to reduce stress caused by input operations.

  That is, an input / output integrated device that can be directly written on the display screen with a pen and an information processing device that operates in conjunction therewith are provided. Character writing enables continuous recording by scrolling in a predetermined direction. On the other hand, the past recorded information is displayed on both the reduced display portion displayed on the left side in the scroll direction and the actual size display portion displayed on the right side.

  Further, an enlarged copy of the reduced display portion can be performed on the actual size display portion. That is, it is possible by drawing a circle with a thick line so as to surround a desired area in the information recorded in the reduced display section. The range including the circumference of this circle or the range partitioned by a predetermined partition line is enlarged and copied on the actual size display section. This copy content is identified and stored by the stroke information. Furthermore, these handwritten character information can be converted into character data by the character recognition means. Character data is data that can be searched for characters.

  Therefore, in Patent Document 2 described above, even a huge amount of medical chart information is arranged and facilitated to search, and therefore, it is possible to cope with the necessity of character recognition of character portions from recorded information and conversion to character data. That is, it is easy to search the character data as a keyword from the storage means for recording and holding the converted character data.

  However, in Patent Document 2 described above, the specific storage means for the converted character data is not clear. Even if the area converted into the character data can be discriminated by the stroke information of the thick line or partition line of the circle specifying this area, the search means is unknown. In particular, medical charts in medical institutions have many identical character data, especially in patients over a long period of time, and the number of hits is very large when searching, making it difficult to select them. That is, even if retrieval is performed using character data in order to extract a desired portion of the original handwritten medical chart, a lot of labor is required thereafter, which may hinder smooth work. Therefore, there is a need for means for easily searching for the designated area.

  Also, during busy medical practice, handwritten characters often do not form sentences in normal medical records. For this reason, even the handwritten person needs time until it understands that it is difficult to read when a long time has passed. Accordingly, it is necessary to easily display the handwritten character portion of the medical chart and display it on the screen.

JP 2000-325314 A JP 2003-225209 A (FIGS. 2 and 10)

  The first problem to be solved is that an electronic information recording system in which handwritten characters are lined up with similar contents, such as a medical chart in a medical institution, cannot easily search for a desired range location. In particular, it is difficult to search the range specified by handwritten character information from character data that can be converted and searched.

  Also, the second problem is that it is difficult to read as a sentence in an electronic information recording system in which words with missing complements are lined up in images, such as medical records, especially in the case of past recordings that have passed the month and day, There is a possibility that a situation that cannot be understood will occur.

  In any case, it is the most precious treatment time for doctors.

  In the present invention, a user who is a doctor draws a handwritten character portion of a medical chart that has become electronic information on a display screen so as to surround it with a surrounding line, recognizes this surrounding line with stroke information and designates it as a tag. One of the main features is that a tag mark is added at a predetermined position, and at least stroke information of the surrounding line is input and recorded as “enclosed stroke information” as tag information. As a result, since the “enclosed stroke information” is included in the tag information, a desired range location can be easily searched from the position information included in the stroke information.

  Another main feature is that, when video characters within the range specified by the tag are converted into character data by the character recognition means, summary text is recorded and held in a summary sentence by a dictionary created in advance. And As a result, since the handwritten characters in the range searched by the tag information are displayed on the screen as easy-to-read typeface text, the text can be easily understood.

  Specifically, handwritten electronic information input from the input / output device is received by the input / output processing device and stored in the storage device, and the handwritten electronic information stored in response to the request from the input / output device is displayed on the screen of the input / output device. In the handwritten electronic information recording system displayed above, the input / output processing device is configured to have the following functions.

  Basically, the input / output processing device recognizes the description information of the handwritten electronic information as stroke information, records and saves it in the storage device, and displays a predetermined area on the handwritten electronic information displayed on the screen from the input / output device. When the encircling line information specified by enclosing is received, a tag mark is added to a predetermined area, and the encircling line information is recognized by the stroke information as “enclosed stroke information”, and the enclosed stroke information is added to the tag mark. A first feature is that the storage device is configured to record and save the corresponding information.

  The handwritten electronic information recording system further includes a character recognition device that converts designated information of the handwritten electronic information into character data and displays the character data on the screen, and the input / output processing device is surrounded by a surrounding line. The configuration is such that the handwritten description information in the area is extracted, converted into character data using a character recognition device, displayed on the screen, and recorded and stored in the storage device in association with the “enclosed stroke information”. It has 2 features.

  Further, the skeleton point coordinate sequence included in the surrounding stroke information is set based on a head reference position in a predetermined section of handwritten electronic information, and the input / output processing device includes a plurality of handwritten electronic information in the predetermined section. It is desirable that the character data corresponding to the tag mark be structured into a sentence.

  In addition, the input / output processing device has summary creation software that forms words by supplementing phrases from simple fixed-form character data, and summarizes the character data converted by the character recognition device using the summary creation software. Desirably configured to generate information. The summary creation software can also process character data input from the input / output device by the input / output processing device.

  Therefore, when the input / output processing device retrieves character data of handwritten electronic information recorded and stored in the storage device from the input / output device and displays it on the input / output device, tag information corresponding to the character data displayed on the screen is displayed. And the original handwritten description information can be searched from the tag information and displayed on the screen.

  Since the handwritten electronic information recording system of the present invention recognizes the surrounding line of the handwritten character part by the stroke information and designates it as a tag, the desired region of the handwritten character part designated by the surrounding line from the position information included in the stroke information Therefore, there is a first effect that a desired area can be easily searched.

  Further, the input / output processing device has summary creation software that forms words by adding words from simple fixed character data, and generates summary information from the character data converted by the character recognition device using this software. Therefore, there is a second effect that the written information can be easily understood.

  Hereinafter, as an example of the handwritten electronic information recording system, a handwritten electronic medical record system that processes a handwritten medical record recorded with electronic information in the medical field will be described. Therefore, the handwritten electronic information is medical record description information, and the user is a doctor.

  In order to achieve the purpose of easily searching for a desired location from the chart data, the chart description information stored in the storage device using the stroke information is displayed on the display screen of the output device. The stroke information is for recognizing a surrounding line input from the doctor on the display screen, and is referred to as “enclosing stroke information” to distinguish it from stroke information in characters.

  When the system receives a tag designation surrounded by a surrounding line input from the doctor on the display screen, the system specifies the tag in the chart description information area surrounded by the surrounding line, and at the predetermined position the tag mark and Enter the tag information. The tag information includes, for example, related information including a chart reference position, a creation date and time, a tag setter, a patient number, and a department attribute, and if necessary, a meaning is input. That is, a doctor can easily search for a desired range portion from the tag information. The stroke information is a combination of a stroke type determined by the character set, a skeleton point coordinate sequence of the stroke, and a shape parameter such as a thickness. A box is defined as a character set. Therefore, since the “box stroke information” includes the skeleton point coordinate sequence of the stroke, the position information of the frame line or the tag mark is taught.

  In addition, when video characters within the range specified by the tag are converted into character data by the character recognition means, the converted character data is converted into a summary sentence by a pre-created dictionary for the purpose of easily understanding the contents of the medical record. In summary, it is realized by recording and holding as summary information. The summary text is displayed on the screen in typeface, making it easy to see and understand.

  Here, the chart description information will be described with reference to the drawings.

  FIG. 2 is a diagram showing an embodiment of a screen display showing original medical record description information input for each date corresponding to a patient in the handwritten electronic information recording system.

  The original chart record information shown in FIG. 2 is date index information on the left, overview information obtained by reducing the actual record information on the second from the left, and actual medical record information on the right. it's shown. These are displayed continuously in chronological order. Therefore, these screens can be freely scrolled up and down. In addition, the left and right screens can be operated in conjunction with each other. Normally, each screen is freely scrolled, but it has an interlocking function that makes the display position the same by a simple operation such as clicking. ing.

  FIG. 3 is a diagram showing an embodiment when the tag mark 5 is added to the chart description information of FIG. 2 according to the present invention. The chart mark-added chart description information shown in FIG. 3 also has a function such as scrolling as in FIG. 2, but in addition to the above, the function of the tag mark 5 is added. The tag mark 5 can be added by designating a desired range. Tag mark 5 can be freely added or deleted. Details of adding the tag mark 5 will be described later in the embodiment.

  The screens shown in FIG. 2 and FIG. 3 are stored in the storage device via the input / output processing device, for example, by reading the chart description information entered on the “medical chart sheet” with the OCR of the input device. Alternatively, for example, the chart description information described with the entry pen in the chart description format of the display / input integrated apparatus is stored in the storage device via the input / output processing apparatus. At the time of storage, the characters described in the medical chart and the above-mentioned surrounding lines are recorded by known stroke information.

  Next, stroke information indicating a character line in a character code will be described with reference to FIG. FIG. 4 is a diagram for explaining an example of the skeleton point coordinate sequence of the stroke 6 included in the stroke information.

  The stroke 6 which is one character line of the chart description information shown in the figure recognizes a line freely drawn in the chart as an aggregate of points by the information processing apparatus. Therefore, the stroke 6 is recognized by a continuous coordinate sequence such as, for example, the strokes S (x100, y96), S (x100, y95). That is, the stroke is stored as a line by a coordinate sequence. Therefore, the character line recording based on the stroke information has a better character quality than the recording based on the video pattern, and is therefore widely used for character recognition and recording.

  The summary information extraction from the chart description information will be described with reference to FIG. FIG. 5 is a diagram for explaining an example of summary information extraction created by drawing an enclosing line 7 on the chart description information.

  In FIG. 5, a surrounding line 7 encloses a portion where it is desired to summarize medical record description information. The encircling line 7 is drawn on the screen by the doctor using, for example, a mouse or an input pen. The encircling line 7 may have any shape, but for the convenience of summarization, a shape that makes the range clear is desirable. The encircled line is exemplified by a closed thick line, but the line type is not limited, and the encircled line can be identified by special stroke information if the positions of the start point and end point of the stroke are close. When this encircled line 7 is recognized as “enclosed stroke information” from the stroke information of the chart description information, for example, a tag mark 5 of a flag as shown in FIG. Is displayed.

  In FIG. 5, each piece of description information in a plurality of ranges surrounded by a surrounding line 7 is information extracted as summary information, and is converted into summary information by a summary creation program. When the approximate date “around October 1998” is not handwritten in the chart description information, it is directly input by a doctor, for example, from a keyboard.

  FIG. 6 is an example of summary information corresponding to medical chart information written within one date. When a summary information display request is received and displayed, a plurality of series of description information is collectively displayed on a screen as shown in the figure.

  Example 1 of the present invention will be described with reference to the drawings. Even though the functions unrelated to the present invention are essential for the system, the description thereof is omitted together with the drawings.

  FIG. 1 is a diagram showing an embodiment of functional blocks in a handwritten chart of a handwritten electronic information recording system according to the present invention. This handwritten electronic information recording system includes an input / output device 1, an input / output processing device 2, a storage device 3, and a character recognition device 4.

  The input / output device 1 includes an input device 11, an output device 12, and a display input integrated device 13. The input / output processing device 2 includes a chart information input / output processing unit 21, a stroke recognition processing unit 22, a tag information processing unit 23, and a summary information processing unit 24, and executes system control and calculation using a program. In addition, the storage device 3 includes a stroke information storage unit 31, a tag information storage unit 32, a summary information storage unit 33, and a sub chart information storage unit 34.

  Here, the storage device 3 is, for example, a single or a plurality of magnetic disks, optical disks, ROMs, RAMs, IC cards, and magnetic tapes for storing data electromagnetically or optically, or a single or a combination thereof. Moreover, at least one of the mass storage type storage devices operated by a changer or the like is included.

  Next, each component shown in FIG. 1 will be described.

  The input device 11 includes, for example, an input operation unit for at least chart information, a surrounding line, and tag information among a keyboard, a numeric keypad, a mouse, a trackball, an input pen, an input tablet, a data glove, an OCR, an image scanner, a microphone, and the like. Including. The output device 12 includes, for example, at least a screen display unit for information based on video data and character data among a display screen, a data scope, a printer, and the like. The display input integrated device 13 is, for example, an input tablet including a display screen and an input pen that directly writes on the display screen.

  The medical record information input / output processing unit 21 is connected to a device in the input / output device 1 and executes data exchange and functional processing thereof. The stroke recognition processing unit 22 recognizes the line that forms the character from the video information described in the medical record input from the input / output device 1 via the medical record information input / output processing unit 21 as the character line. The data is sent to the stroke information storage unit 31 for recording and storage. The character line and stroke information will be described later with reference to FIG.

  When the stroke recognition processing unit 22 detects, for example, the stroke information of the encircling line 7 in FIG. 5 from the video information input in the chart description information, the tag information processing unit 23 passes the chart information input / output processing unit 21. To receive notification of tag occurrence. In response to this notification, the tag information processing unit 23 obtains a tag generation program from the tag information storage unit 32, and records a predetermined tag flag tag 5 (see FIG. 3), for example, together with an information input frame (not shown) in the chart. Add to information and display on screen.

  A tag position based on stroke information, a creation date / time based on clock information, and the like are automatically added to the tag information. Further, tag meanings such as tag color, shape, and comment character information may be input to the information input frame, and an image, sound, or the like may be additionally input. The tag mark color and shape can be simplified by, for example, displaying a flag list on the screen and selecting from the flag list in the tag generation program. The color can be selected based on a predetermined meaning such that “red” is “caution” and green is “follow-up”. It is not necessary to additionally input information other than predetermined information in the information input frame.

  When the tag information is formed by the tag information processing unit 23, the summary information processing unit 24 reads the chart description information in the encircling line 7 corresponding to the tag information in the storage device 3. The description information is extracted and received by the character data converted through the character recognition device 4. The summary information processing unit 24 summarizes the character data using summary creation software (hereinafter abbreviated as summary software), that is, a summary dictionary and a control program installed in the summary information storage unit 33. The summary information processing unit 24 also receives, for example, character data input from a keyboard in response to a request from the input device 11 via the chart information input / output processing unit 21 and summarizes it using the above summary software.

  As shown in FIG. 7, the summary information processing unit 24 stores each of the extracted extracted summary data shown in FIG. 5 in the summary information storage unit 33 as summary information associated with the tag information or each enclosure 7. To do.

  In the stroke information storage unit 31, the patient number, the reporter, the description department attribute, the description date time, and other description items included in the chart description information received from the stroke recognition processing unit 22 include character lines that constitute those characters. As shown in FIG. 4, it is converted into stroke information and stored, for example, by a continuous coordinate sequence such as stroke S (x100, y96), S (x100, y95). Video information other than characters included in the medical record information can also be converted into stroke information that is drawn in a line shape, and may be converted.

  In addition, when the tag information is stored in the tag information storage unit 32, the stroke information storage unit 31 includes, for example, a portion of the stored chart description information surrounded by the surrounding line corresponding to the tag information. , Strokes SK (x100, y96), SK (x100, y95)... Are output as summary information to the summary information processing unit 24 via the character recognition device 4.

  In the tag information storage unit 32, the patient number processed by the tag information processing unit 23, the creator name of the encircling line, the department attribute, the creation date time, the attribute information of this area, the date information in the medical chart of this area, and the others The description information is stored as stroke information of the tag area as shown in FIG. 8, for example, by a continuous coordinate sequence such as stroke K (x100, y96), K (x100, y95).

  Here, referring to FIG. 8, the tag information storage unit 32 notifies the stroke information storage unit 31 of a portion corresponding to the stored tag information in the chart description information as summary information. Accordingly, the summary text stored in the summary information storage unit 33 is stored corresponding to each stroke information of the tag area stored in the tag information storage unit 32.

  The summary information storage unit 33 receives the character data information summarized by the summary information processing unit 24 and, as shown in FIG. 8, corresponds to the stroke information of the tag area in the tag information storage unit 32, that is, for each tag information. Recorded and stored. As described above, the character data summarized by the summary information processing unit 24 corresponds to the chart description information in the area surrounded by the encircling line 7 as shown in FIG. What is converted into the stroke information is further converted into a text sentence by the character recognition device 4. Therefore, the designated character can be searched from the summary text stored in the summary information storage unit 33.

  Furthermore, as shown in FIG. 9, the chart reference position 8 can be given to each tag information based on the date corresponding to the top of the display position on the chart description information screen or the top pointer of the display position within the date. The chart reference position 8 is unified position information included in each summary information when a plurality of pieces of summary information are collected within the same date, and is referred to as a “first reference position” as a general name. Therefore, when outputs of a plurality of tag areas are collected on the same date, the chart reference position 8 is given to the plurality of tag information with the same value. As a result, at the display position 9 on the screen shown in FIG. 9, a plurality of summary information that is typified by text sentences and grouped into one section is changed to the summary information shown in FIG. 6 instead of the original chart description information. Is displayed on the batch screen.

  The sub medical record information storage unit 34 automatically adds medical record information that cannot be acquired with stroke information, such as pictures and images such as pictures and graphics that cannot be recorded with stroke information, voice, access time, operator name, position on the medical chart, etc. Stored together with the index and identification information. These pieces of information are associated with the description information stored in the stroke information storage unit 31 by the identification information. This content can be stored in the stroke information storage unit 31 together with the stroke information and included in the chart description information. In this case, the secondary chart information storage unit 34 is abolished.

  The character recognition device 4 detects character stroke information from known video data and converts it into character data. Here, the character recognition device 4 converts the summary information extracted from the storage information converted into the stroke information by the stroke information storage unit 31 in accordance with the tag information instructed from the tag information storage unit 32 into the text information. It is converted into text data of text and sent to the summary information processing unit 24.

  Next, the main procedure of tag mark generation will be described with reference to FIG. 10 together with the drawings from FIG. Since this is a major procedure, incidental procedures in the event of a failure are omitted.

  First, it is assumed that the chart description information is displayed on the screen (step S1) as shown in FIG.

  A doctor draws a surrounding line 7 as shown in FIG. 5 in a desired range of the chart description information displayed on the screen using, for example, a mouse as the input device 11. Therefore, the chart information input / output processing unit 21 receives the drawing data from the input device 11, sends the received data to the display screen of the output device 12, and displays the screen (step S2). This range can be freely specified. Further, the shape of the surrounding line 7 is also free.

  The doctor confirms that the position of the surrounding line is correct on the screen and determines the position of the surrounding line 7. Accordingly, the chart information input / output processing unit 21 receives the notification of the surrounding line position determination from the input device 11 (YES in step S3), and therefore sends the determined data of the surrounding line 7 to the stroke recognition processing unit 22. The stroke recognition processing unit 22 searches the position of the encircling line 7 and its stroke information (procedure S4) and confirms the acquisition of the stroke information of the encircling line (YES in step S5). 21 is notified. The stroke information of the surrounding line includes position information of the surrounding line.

  The medical record information input / output processing unit 21 drives the tag information processing unit 23 and, based on the stroke information of the surrounding line received from the stroke recognition processing unit 22, at a predetermined position, for example, the sentence head position in the surrounding line, for example, FIG. The tag mark 5 is linked to the tag mark 5 and a pointer is displayed on the screen (step S6), for example, at the tag information entry frame and at the head position in the tag information entry frame. Here, for example, when the pointer position is aligned with the tag mark 5, the flag list of the tag mark color and shape is displayed on the screen as described above, and the color and shape can be selected.

  The doctor can execute “meaning” in the tag information entry frame according to the pointer on the screen, for example, by inputting characters from the keyboard of the input device 11. Accordingly, the chart information input / output processing unit 21 that has received an input from the input device 11 displays characters in the tag information entry frame on the display screen of the output device 12 (step S7). At this point, character data is used in the tag information entry frame. Further, for example, when it is input from the display / input integrated device 13 by a description with an input pen, it is video information. Of course, meaning information may be left blank.

  When the doctor performs an input operation in the tag information entry frame or confirms at least the tag mark and its position, the chart information input / output processing unit 21 receives a notification of the tag information input determination from the input device 11 ( YES in step S8). At this time, the determined tag meaning information is sent to the tag information processing unit 23. The tag information processing unit 23 performs the chart reference position, the position of the tag mark, the stroke information of the enclosing line indicating the range, the patient information, the doctor information, the department attribute, the date and time specified by the tag, and the date of the chart for the specified tag. Information or the like is read from the chart information as stroke information and automatically recorded, and description information such as semantic information described above is added as stroke information and stored in the tag information storage unit 32 as tag information (step S9).

  However, normally, the designated date and time recorded as described above is automatically obtained from a built-in clock, but patient information, doctor information, department attributes, etc. are input from the input / output device 1 by the doctor so that there is no error in recognition. Input as character data. Therefore, when the meaning information is character data, the meaning information is converted into stroke information by the tag information storage unit 32 and recorded.

  When the tag information storage unit 23 finishes storing the tag information in the tag information storage unit 32 by the procedure S9, the tag information processing unit 23 displays the surrounding line 7, the tag information entry frame, and the meaning information input in the frame from the screen display. Erase and leave only the tag mark 5 on the screen display (step S10). As a result, as shown in FIG. 3 with respect to FIG. 2, the tag mark 5 is added at a predetermined position corresponding to the enclosing line.

  As a result, from the tag mark, for example, when the mouse is clicked, a surrounding line is displayed on the chart description information, and when summary information is stored, for example, the actual size display section or the enlarged display section on the right in FIG. Can be displayed on the screen. Further, the tag information may be displayed on the screen as meaning information among the tag information.

  Here, when the doctor closes the screen, the chart information input / output processing unit 21 accepts an input for closing the screen from the input device 11 (YES in step S11), and thus closes the display screen (step S12) and ends the procedure. To do. When the procedure S11 is “NO” and the next tag setting is performed, the procedure returns to the procedure S2 and the procedure is repeated.

  If the step S5 is “NO” and the stroke information of the surrounding line is not obtained, the tag cannot be created, so the medical record information input / output processing unit 21 displays “tag cannot be created” on the screen (step S13). After receiving the erasure of the surrounding line (step S14), the process proceeds to step S11.

  Next, the main generation procedure of summary information will be described with reference to FIG. Therefore, incidental procedures in the event of a failure or the like are omitted.

  First, it is assumed that the chart description information is displayed on the screen (step S21) as shown in FIG. 3, for example.

  It is assumed that the doctor designates execution of summary generation by, for example, a predetermined click of the desired tag mark 5 of the chart description information displayed on the screen using, for example, a mouse as the input device 11. Based on this click, the chart information input / output processing unit 21 accepts a tag mark selection from the input device 11 (step S22). Upon receipt of the mark selection, the chart information input / output processing unit 21 brings the display screen to the left half, for example, and generates the remaining right half as a summary creation screen (step S23).

  In FIG. 12, the two-screen display screen shown in FIG. 3 is reduced to one-half of the left side, and a summary creation screen is generated on the right half.

  FIG. 13 reduces the display of one screen of the actual size display or the enlarged display of FIG. 3 to one-half of the left side, and generates a summary creation screen on the right side.

  Next, the doctor designates the summary transfer destination of the chart description information corresponding to the tag mark by “dragging and dropping” the selected tag mark on the summary creation screen with, for example, a mouse. With this designation, the chart information input / output processing unit 21 accepts the selected tag determined from the input device 11 and the summary transfer destination of the area corresponding to this tag (YES in step S24). Next, since the chart information input / output processing unit 21 accepts, for example, a transcription request or a transcription start request by a predetermined click of the mouse from the input device 11 (procedure S25), the position information of the selected tag mark is sent and tag information processing is performed. The unit 23 is driven.

  The tag information processing unit 23 sends the tag position information to the tag information storage unit 32, and the tag information is obtained from the position information. The tag information storage unit 32 drives the stroke information storage unit 31 with the obtained tag information. As a result, stroke information corresponding to the chart description information in the encircled line area is acquired from the stroke information storage unit 31 (step S26). This stroke information is sent to the character recognition device 4 as summary information and converted into character data (step S27).

  The character data converted by the character recognition device 4 is sent to the summary information processing unit 24. The summary information processing unit 24 uses the built-in summary software to create summary information of the corresponding tag area, record and store it in the summary information storage unit 33, as described with reference to FIG. S28). At the same time, the summary information processing unit 24 notifies the chart information input / output processing unit 21 of the tag information, and displays the summary document at the location specified on the display screen of the output device 12 (step S29).

  Here, when the doctor closes the screen, the chart information input / output processing unit 21 accepts an input for closing the screen from the input device 11 (YES in step S30), and thus closes the display screen (step S31) and ends the procedure. To do.

  When the procedure S30 is “NO” and the doctor sets the next tag without closing the screen, the procedure returns to the procedure S22 and the procedure is repeated. For example, when the doctor selects three tag marks in the chart description on the same date shown in FIG. 7 and extracts summary information, the procedure repeats the procedure from “NO” in step S30 twice to obtain three summary information. Is recorded in the summary information storage unit 33 and displayed on the screen. The doctor compares the chart description information and summary information on the screen, and for example, missing information such as date is additionally input as character data from the input device, and furthermore, since the summary information is character data, the stored data can be corrected. is there. As a result, as shown in FIG. 6, the handwritten medical chart description information is displayed on the screen in an easy-to-read manner with printed text text.

  That is, as summarized in FIG. 14, the summary information storage unit 33 in FIG. 1 stores summary information summarized for each tag area stored in the tag information storage unit 32 in a text sentence. Character search is possible with The summary information retrieved from the character data and read from the tag area designated by the retrieval corresponds to the tag information in the tag information storage unit 32. The tag information includes the stroke information of the surrounding line, that is, “surrounding stroke information”. Further, the surrounding stroke information has position information in the chart description information by handwriting of the corresponding surrounding line.

  Therefore, the system according to the present invention can quickly detect the corresponding tag area as a result of the character search using the image-displayed summary information, so that the corresponding original chart record information can be easily extracted from the stroke information storage unit. Can be displayed.

  As described above, if there is no input for “semanticization” when specifying the range of the chart description information with an enclosing line to set the tag, the user operating this system will need to read the tag information when implementing the system. No additional data is required. That is, the user's work is simple. For example, the access time can be determined from a built-in clock. For example, the user name can be determined by accessing the system with the user name and password. Alternatively, the tag mark position in the chart can be determined from the chart coordinates by the surrounding stroke information. Therefore, each information item for tag setting can be automatically input.

  For example, in FIG. 1, the input / output device, the input / output processing device, and the storage device, which are the major components, are almost unchanged, but each internal configuration includes, for example, a secondary medical record information storage unit in the stroke information storage unit. Can be abolished.
