  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a schematic block diagram of an embodiment of the present invention applied to a system comprising a mobile terminal 10 and a server 40. FIG. 2 shows an operation flowchart of the mobile terminal 10 as a client, and FIG. 3 shows an operation flowchart of the server 40.

  The mobile terminal 10 as a client can connect to the server 40 via the network 30 and browse and display the electronic medical record data of the server 40. The mobile terminal 10 is a communication terminal having a communication function capable of simultaneously displaying text information and graph information. For example, the mobile terminal 10 is a mobile phone or an information terminal having a small screen.

The mobile terminal 10 includes a CPU 12 that controls the whole, a memory 14 for the CPU 12, and an operation device 16 for character input, zoom operation, and scroll operation. The communication device 18 communicates with the server 40 via the network 30. The display image generation apparatus 20 generates image data indicating a line diagram, a line graph, a pie chart, and the like from the history data from the server 40 and the vector data indicating the graph. The VRAM 22 stores data indicating text and images to be displayed on the display device 24. When the display device 24 is validated, the data stored in the VRAM 22 is read at a fixed period and a corresponding image is displayed on the screen. To do. CPU12 via the bus 26, a memory 14, an operation device 16, the communication device 18 to communicate with the display image generation unit 20 and the VRAM22 and the display device 24, and controls these.

  On the other hand, the server 40 includes a CPU 42 that controls the whole, a memory 44 for the CPU 42, an electronic medical record database (DB) 46, a history example database (DB) 48, a display data generation device 50, and a communication device 52. To do. The CPU 42 communicates with the memory 44, the electronic medical record database (DB) 46, the history example database (DB) 48, the display data generation device 50, and the communication device 52 via the bus 54.

  The electronic medical record database 46 stores electronic medical record data of a plurality of patients, and medication (including injection) and examination history are recorded in time series in the electronic medical record of each patient.

  The history example database (DB) 48 includes typical history patterns in time series of medication and examination for each case and each drug, for example, after breakfast once a day or after meal three times a day. A history pattern is stored. For such history example data, for example, an average of values is calculated from statistical data for each case in which patient characteristics are ignored. The patient is classified in advance by a specific index, and an average is calculated by this method for each classification. You may produce | generate according to the combination of a case. Certain drugs have a correlation with the examination, and the examination pattern can be estimated from the dosage pattern, and the dosage pattern can be estimated from the examination pattern.

  Further, the patient attributes (age, sex, weight), medical history, past test values, and actual medication pattern data for the change thereof may be accumulated and statistically processed to be stored in the history example database 48. In this case, in response to a request for history example data from the mobile terminal 10, the server 40 refers to the patient's attributes, medical history, past examination values, and changes thereof, and records history example data to be transmitted to the mobile terminal 10. decide.

  The operation of this embodiment will be described with reference to FIGS. The user of the mobile terminal 10 activates application software for viewing the electronic medical record on the mobile terminal 10 and inputs a patient ID for viewing the electronic medical record using the operation device 16 (S1). The CPU 12 transmits an electronic medical record request including the input patient ID, terminal ID, and display capability of the display device 24 to the server 40 via the communication device 18, and receives the electronic medical record data (S2). The terminal ID is identification information that identifies the mobile terminal 10 and is used, for example, to determine whether the terminal is permitted to access the electronic medical record database 46. In a system that limits users who can access the electronic medical record database 46, the user ID is also transmitted from the portable terminal 10 to the server 40.

  The display capability of the display device 24 generally indicates the screen size or the number of display pixels, and generally determines the layout for displaying individual items of the electronic medical record information. As will be described later, the server 40 transmits drawing data indicating a graph or a graphic to be transmitted to the mobile terminal 10 in consideration of the display capability of the mobile terminal 10 that has accessed. The drawing data is data representing a vector such as a graph or a diagram to be displayed.

  In the server 40, the CPU 42 waits for reception of a request from the portable terminal 10 by the communication device 52 (S21), and executes processing according to the received request (S22 to S30). At this stage, the CPU 42 receives an electronic medical chart request transmitted from the mobile terminal 10 (S22). The CPU 42 reads out the electronic medical record that matches the patient ID from the mobile terminal 10 from the electronic medical record database 46, and transmits it to the mobile terminal 10 via the communication device 52 (S25). Specifically, in step S25, the server 40 displays fixed data (patient ID, patient name, sex, address, etc.), item names, and display formats (text, graphs, etc.) of each item of the corresponding patient. It transmits to the portable terminal 10.

CPU12 of the portable terminal 10, the electronic medical record data received, historical example data items to be displayed graphs, obtains by requesting the server 40 (S3). In response to the request for the history example data (S23), the server 40 reads the history example data of the specified item (for example, medicine or examination) from the history example database 48 and transmits it to the mobile terminal 10 (S26). When the history example data stored in the history example database 48 reflects patient attributes (age, gender, weight), medical history, past examination values, changes thereof, etc., the server 40 In response to a request for history example data from 10, the closest history example is searched using a statistical method such as a square error in view of patient attributes, medical history, past test values, and changes thereof, 10 to send.

  The CPU 12 of the mobile terminal 10 determines the layout or logical screen configuration according to the display capability of the display device 24 (S4).

  The CPU 12 of the portable terminal 10 requests the server 40 for drawing data of items (for example, a medication pattern and a test pattern) to be displayed on a graph necessary for the initial screen displayed on the display device 24 (S5).

  In consideration of a low-speed network in the initial screen, the CPU 12 first requests the server 40 for drawing data having a scale that is one step coarser than the scale of the initial screen (referred to as initial scale), and then requests drawing data of the initial scale.

  When the CPU 12 receives drawing data having a scale that is one step coarser than the initial scale, the CPU 12 causes the display image generation device 20 to generate image data indicating a provisional graph or figure by using the history example data received earlier. It is stored in the VRAM 22 (S6). The CPU 12 also causes the display image generating device 20 to generate image data indicating a graph or a graphic based on the initial scale drawing data for the item that has received the initial scale drawing data, and stores it in the VRAM 22 (S6). Thereby, even if the network 30 is low speed, provisional display using the history example can be performed at an early stage, and the contents can be grasped for the time being. By updating to a graph or the like corresponding to the drawing data that matches the scale, the user can be informed of the correct content.

  Before and after step S5, the CPU 12 stores the item name and data to be displayed on the display device 24 in the VRAM 22 according to the layout determined in step S4, and validates the display on the display device 24 (S6). As described above, when the display device 24 is activated, the display device 24 accesses the VRAM 22 and displays the display data stored in the VRAM 22, that is, the item names and their contents on the screen in the previously determined layout. To do. Thereafter, the display device 24 periodically accesses the VRAM 22 and displays the contents stored in the VRAM 22.

  The CPU 12 monitors the presence or absence of a horizontal or vertical scroll operation (S7) by the operation device 16 and a zoom operation (S9) for enlarging / reducing the time scale. When there is a scroll operation (S7), the CPU 12 updates the data stored in the VRAM 22 with the display data of the item newly entered in the display area by scrolling (S8). Thereby, the item after scrolling and its contents are displayed on the screen of the display device 24.

  When there is a zoom operation for changing the time scale (S9), the CPU 12 updates the display of the display device 24 to the time scale after zooming (S10). FIG. 4 shows a detailed flowchart of the display update (S11). Note that what needs to be updated by changing the time scale is data that expands or contracts by changing the scale, that is, graph data.

  Even in the case of a zoom operation, there is a case where the mobile terminal 10 caches and holds drawing data displayed before by the memory 14 by temporarily reducing and then enlarging. There is no need to request the same drawing data. Therefore, in the display update (S10), the CPU 12 of the mobile terminal 10 first checks whether drawing data for the time scale after the zoom operation is held in the memory 14 (S41). If not, the CPU 12 of the mobile terminal 10 first requests the server 40 for drawing data of one or more items on the time scale after the zoom operation, specifying the size of the display area after zooming ( S42). When there is room in the network 30, the CPU 12 transmits requests to all the necessary items at once to the server 40, and when there is no room in any of them, the requests are sequentially sent to the server 40 over time. You may make it transmit. This is because, as will be described later, the display can be temporarily replaced by history example data.

  In response to a request for drawing data for necessary items (S24), the CPU 42 of the server 40 sorts the requested items in order of priority (S27). Specifically, the priority is the magnitude of the variation of the data value, and the item having the larger variation is transmitted earlier.

  The CPU 42 instructs the display data generation device 50 to read the data value of the corresponding item from the electronic medical record database 46 for the items in the sort order, and generate drawing data that matches the scale to be displayed on the portable terminal 10 ( S28). CPU42 transmits the produced | generated drawing data to the portable terminal 10 by the communication apparatus 52 (S29). Steps S28 and S29 are repeated until transmission of drawing data is completed for all requested items (S30). When transmission of drawing data is completed for all requested items (S30), the process returns to step S21.

  The CPU 12 of the portable terminal 10 confirms whether drawing data matching the time scale after the zoom operation has been received from the server 40 for each item to be displayed on the time scale after the zoom operation (S43). For the received items (S43), the CPU 12 causes the display image generating device 20 to generate image data from the received drawing data, and stores the generated image data in the VRAM 22 (S44). Since the display device 24 periodically updates the display screen with the data stored in the VRAM 22, the display screen of the display device 24 is thereby updated to the display content of the time scale after zooming.

  For items that have not been received (S43), the CPU 12 matches the time scale after zooming from the drawing data before zoom operation and the history example data of the item for items that can use drawing data before zoom operation (S45). The temporary display drawing data to be generated is generated (S46). For example, from the drawing data before the zoom operation, the execution period and the average value during that period can generally be acquired. When the history example data for the medication is the frequency and amount in units of days, the provisional display drawing data can be generated by arranging them evenly in the implementation period. Of course, when the history example data also defines a medication interval, it is arranged within the implementation period at that medication interval. When the monotonic increase or monotonic decrease is included in the history example, the provisional display drawing data is determined in consideration of this. The CPU 12 causes the display image generation device 20 to generate image data from the provisional display drawing data determined as described above, and stores the generated image data in the VRAM 22 (S47). It is obvious that the display image generation device 20 may generate image data for display directly from the history example data.

  Steps S43 to S47 are repeated until all items of the graph display in the display area of the display device 24 are updated with image data based on the received drawing data (S48). That is, by temporarily generating display image data from history example data and displaying it, the display screen can be updated to an approximate but highly likely content without waiting for data reception from the server. In other words, the display can be updated at a practical speed even in an environment where the data transmission rate of the network 30 is low and even if the resources of the mobile terminal as a client are poor.

  When the display by the drawing data from the server 40 is completed (S48), the process shown in FIG. 4 is terminated and the process returns to step S7 in FIG.

FIG. 5 shows a display example. FIG. 5A shows an example of a weekly history of medicine A in January. FIG. 5B shows a provisional display example using the history example when the history shown in FIG. 5A is zoomed to the daily scale. FIG. 5C shows a display example of an actual history adapted to the scale displayed after the provisional display shown in FIG. Here, as an illustrative example, medicine A is prescribed in the morning and evening from January 1 to January 21, from January 1 to 10, and is prescribed only in the morning after 11th. Suppose that A typical dosing pattern is taken three times a day in the morning, noon and night. As shown in FIG. 5 (b), in the provisional display, the pattern is taken three times a day from January 1 to 15 (actually thereafter), but a daily scale drawing reflecting the actual history As the data is received, the graph is updated to reflect the actual history as shown in FIG.

In this way, in this embodiment, a change in the time scale is temporarily replaced with a temporary display such as a graph generated from the typical history data while waiting for the reception of drawing data matching the changed time scale. Therefore, even when the mobile terminal 10 having a low resource or a low-speed network is used, the history information can be quickly confirmed. Since it is updated immediately with the correct history, it is possible to prevent erroneous recognition.

  When historical data is displayed in time series as a graph such as a diagram, the amount of data on the network generally increases as the time scale becomes more detailed, that is, as it is displayed in smaller time units. Therefore, if the network is overloaded with the time scale drawing data for the graph display of the history of the desired time scale (detail level), the server requests the rough time scale drawing data and continues. Requests the original timescale drawing data from the server. Then, a graph of the target time scale is generated and temporarily displayed from the drawing data that arrives first and the history example data that has been received separately, and a graph of the target time scale is generated from the drawing data that arrives later And formally display.

  In addition, when there is no change in the dosage once and there is a change in the frequency as in the medication history, the medication status is provisionally determined based on the medication start date and time, medication end date and time, and typical medication history pattern data. Can be graphically displayed. Therefore, when there is data of a medication history example, the medication status can be provisionally displayed in a graph by receiving the medication start date and time and medication end date and time from the server first. And a viewer can be made to recognize the correct content by updating a display with the actual medication history received continuously.

  Although the invention has been described with reference to specific illustrative embodiments, various modifications and alterations may be made to the above-described embodiments without departing from the scope of the invention as defined in the claims. This is obvious to an engineer in the field to which the present invention belongs, and such changes and modifications are also included in the technical scope of the present invention.
