Description

  The present invention relates to a medical information processing system in a thin client environment.

  At present, attempts are being made to construct medical information processing systems in hospitals in a thin client environment. In a medical information processing system in a hospital, it is necessary to support a workflow executed in the hospital. Even in a thin client environment, the workflow must naturally be taken over between the thin clients.

  As a prior art, there is one in which the last state of the previous time is stored in a medical image information system when taking over a workflow. However, when this conventional technique is used, the user can understand only the last state, and cannot understand the contents (background) up to the last state. In addition, since information handled by the medical information processing system in the hospital includes patient information, care must be taken in handling patient information when taking over a workflow. In addition, since operations related to human life are performed in hospitals, it is important to improve the efficiency of operations, and it is important to efficiently execute workflows.

  Patent Document 1 shows an example of displaying an image of a heart in an ultrasonic diagnostic apparatus.

  An object of the present invention is to provide a medical information processing system that enables efficient handover of a workflow.

  A medical information processing system according to a first aspect of the present invention executes an application program according to a user operation, and executes an application unit that processes medical information, and a control that controls the execution unit to interrupt the execution of the application program A storage unit that stores operation information related to user operations performed between the interruption point at which the interruption was performed and a predetermined point before the interruption point, and a processing result of the application program. A display unit having a display for playing back, and a playback unit that plays back a user operation between the interruption time point and the predetermined time point on the display according to the operation information.

  According to the present invention, it is possible to efficiently take over a workflow.

The figure which shows the network environment of the medical information processing system 1 which concerns on this embodiment of this invention. The functional block diagram of the process which the medical information processing system of FIG. 1 performs according to the application program for taking over the workflow which concerns on this embodiment. The figure which shows an example of the initial display screen of the ultrasonic application program in the reproduction | regeneration stage of moving image data displayed on the display part of FIG. The figure which shows an example of the display screen of the ultrasonic application program regarding moving image reproduction displayed on the display part of FIG.

  Hereinafter, a medical information processing system according to an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing a network environment of a medical information processing system 1 according to this embodiment. As shown in FIG. 1, a medical information processing system 1 includes a server device 3 and a plurality of client devices 5-1, 5-2, 5-3, 5-4 connected via a network. It is a thin client type network system built in Hereinafter, for the sake of simplicity, the client devices 5-1, 5-2, 5-3, and 5-4 are collectively referred to as the client device 5 unless it is necessary to distinguish between them.

  The client device 5 has an input device for giving various instructions and information to the server device 3. An input signal generated by the input device is transmitted to the server apparatus 3 via the network. The server device 3 has a storage device such as a hard disk for storing various application programs. The server device 3 also has a CPU (central processing unit) that executes these various application programs. The CPU of the server device reads an application program for processing medical information from the storage device in accordance with an input signal from the client device 5 and develops it, and processes the medical information in accordance with the read application program. At this time, the server device 3 generates display screen data when the application program is executed, and transmits the generated display screen data to the client device 5 via the network. The client device 5 has a display for displaying a display screen. The client device 5 receives display screen data from the server device 3 and displays the supplied display screen on the display.

  There may be a case where it is desired to take over the workflow with different or the same client device 5. For example, the user executes the application program on a certain client device 5-1, and interrupts the process on the way. Then, after a certain period of time, the user may want to resume the interrupted application program using the client device 5-1 or the client device 5-3 installed at a different location from the client device 5-1. At this time, it becomes necessary to take over the workflow between the client devices 5-1 or between the client device 5-1 and the client 5-3.

  The medical information processing system 1 according to the present embodiment includes a function that allows a user to take over a workflow reliably and easily, that is, a takeover application program, in view of the necessity of taking over such a workflow.

  FIG. 2 is a functional block diagram of processing executed by the medical information processing system 1 in accordance with the takeover application program for taking over the workflow according to the present embodiment. As shown in FIG. 2, the medical information processing system 1 includes an execution unit 31, an execution control unit 33, a reproduction parameter database 35, an operation information storage unit 37, an operation information database 39, an event management unit 41, a user authority management unit 43, A processing result storage unit 45, a processing result database 47, a playback unit 49, an operation unit 51, and a display unit 53 are provided. Execution unit 31, execution control unit 33, reproduction parameter database 35, operation information storage unit 37, operation information database 39, event management unit 41, user authority management unit 43, processing result storage unit 45, processing result database 47, and reproduction unit Reference numeral 49 denotes a function of the server device 3. The operation unit 51 and the display unit 53 are functions of the client device 5.

  The execution unit 31 executes an information processing application program for processing medical information in accordance with a user operation via the operation unit 51 under the control of the execution control unit 33.

  The execution control unit 33 controls the execution unit 31 in accordance with a user operation via the operation unit 51. For example, the execution control unit 33 controls the execution unit 31 to interrupt the execution of the medical information application program when an instruction to interrupt the medical information application program is given via the operation unit 51. In addition, the execution control unit 33 stores, in the reproduction parameter database 35, the reproduction parameter at the time when the interruption instruction is given when the interruption instruction for the medical information application program is given via the operation unit 51. The reproduction parameter is a parameter for reproducing the execution state of the medical information application program at the time when the interruption instruction is given. The reproduction parameter is, for example, a parameter for image processing at the time when an interruption instruction is given. Further, the execution control unit 33 reads the corresponding reproduction parameter from the reproduction parameter database 35 in response to an instruction to take over the workflow via the operation unit 51. Then, the execution control unit 33 controls the execution unit 31 according to the read reproduction parameter in order to reproduce the execution state of the medical information application program at the time of interruption.

  The reproduction parameter database 35 stores the reproduction parameter and the workflow identification information corresponding to the reproduction parameter in association with each other.

  The operation information storage unit 37 acquires operation information related to user operations during execution of the medical information application program, and stores the operation information in the operation information database 39 in time series. Typically, the operation information storage unit 37 stores, in the operation information database 39, operation information related to a user operation performed between an interruption time point when the interruption instruction is given and a predetermined time point before the interruption time point. For example, the operation information storage unit 37 stores operation information in the operation information database 39 in units of a predetermined workflow. The workflow is, for example, one unit from the start to the end of the medical information application program or from login to logout. The predetermined time can be arbitrarily set by the user via the operation unit 51. For example, the predetermined time is 5 minutes before or 10 minutes before the time when the interruption instruction is given. In other words, the predetermined time may be at the start of the medical information application or at the start of the workflow. Specifically, the operation information is display screen (moving image) data or an operation log during execution of the medical information application program. When the operation information is moving image data, the operation information storage unit 37 acquires moving image data displayed on the display during the execution of the medical information application program by using a screen capture function or the like, and acquires the acquired moving image data. Records in the operation information database 39 in time series. When the operation information is an operation log, the operation information storage unit 37 analyzes an input signal from the client device 5 to generate an operation log, and stores the generated operation log in the operation information database 39 in time series.

  The operation information database 39 stores operation information and user identification information of the user who has performed the operation in association with each other. The operation information database 39 stores operation information in association with user identification information of a user who is permitted to reproduce the operation information or a user who is not permitted to reproduce the operation information. Such user identification information can be set by the user via the operation unit 51. The operation information is stored in association with an operation identification number for identifying the operation information.

  The operation unit 51 includes the above-described input device that receives an operation by a user. The operation unit 51 transmits an input signal input by the user via the input device to the server device 3. For example, the operation unit 51 selects operation information to be reproduced in accordance with a user instruction, and transmits an input signal corresponding to the selection to the server device 3. As an input device, a pointing device such as a mouse or a trackball, a selection device such as a mode switch, or a keyboard can be used as appropriate.

  The event management unit 41 manages an input signal from the operation unit 51 and determines a timing for reproducing the operation information. The reproduction timing includes, for example, when the user logs in to the system, when a workflow is selected, and when a medical information application program is activated. This timing can be arbitrarily set via the operation unit 51. Further, the event management unit 41 determines the operation information selected via the operation unit 51 as operation information to be reproduced.

  The user authority management unit 43 performs user authentication when logging in to the server device 3, and the user authenticated by the user has authority to reproduce operation information and specific information (eg, patient information) included in the operation information. It is determined whether or not. Specifically, the user authority management unit 43 determines whether the user is permitted or not permitted to reproduce the operation information to be reproduced based on the user identification information related to the user authenticated by the user. When it is determined that the reproduction is permitted, the user authority management unit 43 supplies a permission signal to the reproduction unit 49. When it is determined that the reproduction is not permitted, the user authority management unit 43 supplies a non-permission signal to the reproduction unit 49.

  The processing result storage unit 45 stores data and parameters (for example, organization images) of reduced images, which will be described later, and processed images (for example, images generated by volume rendering images, wall motion tracking, etc.) obtained by executing image processing. Data of processing results such as blood flow velocity, radial strain, etc.) are stored in the processing result database 47. For example, the processing result storage unit 45 stores, in the processing result database 47, reduced image data that is an image obtained by reducing the display screen at the end of the medical information application program.

  The processing result database 47 stores the reduced image data and the operation identification number in association with each other. Further, when the operation information is an operation log, the processing result database 47 stores the operation log and the processed image data generated by the image processing corresponding to the operation log in association with each other. For example, the processing result database 47 stores an operation log related to an execution request for image processing in association with processed image data generated by the image processing.

  When the permission signal is supplied from the user authority management unit 43, the reproduction unit 49 reproduces the operation information to be reproduced selected by the operation unit 51 on the display of the display unit 53 at the timing determined by the event management unit 41. To do. When the operation information is a moving image, the reproducing unit 49 reproduces the user operation on the display by reproducing the data on the display screen as a moving image. When the operation information is an operation log, the reproducing unit 49 reproduces a user operation corresponding to the operation log on the display by re-executing the operation log. More specifically, the display screen data during the execution of the medical information application program is regenerated according to the operation log, and the regenerated display screen data is transmitted to the client device 5 to display a moving image on the display.

  The display unit 53 includes a display that displays a display screen during execution of the medical information application program. The display unit 53 receives display screen data transmitted from the server device 3 and displays the received display screen on a display. As the display, for example, a CRT display, a liquid crystal display, an organic EL display, a plasma display, or the like can be used as appropriate.

  Next, a typical operation example of the medical information processing system 1 according to the present embodiment will be described by dividing it into types of operation information, that is, display screen data and operation logs. In order to specifically describe the following description, it is assumed that the medical information application program is an ultrasonic application program for processing an ultrasonic image obtained by the ultrasonic diagnostic apparatus. It is assumed that the takeover application program is incorporated in this ultrasonic application program. It is assumed that the operation information is reproduced when the workflow is selected.

(When the operation information is video data)
First, the storage stage of moving image data will be described. In the moving image data storage stage, the operation information storage unit 37 stores the moving image data displayed on the display during execution of the ultrasonic application program in the operation information database 39 in time series. Then, the operation information storage unit 37 receives the input signal related to the suspension instruction of the ultrasound application program from the operation unit 51 as a trigger, and the operation information storage unit 37 stores the moving image data from the predetermined time to the suspension time in the operation information database 39 in time series. Remember me. The predetermined time is, for example, a workflow start time, an execution start time of the ultrasonic application program, an interruption time before a user specified time, or the like. The moving image data before the predetermined time is deleted from the operation information database 39. The user designated time is, for example, 5 minutes, 10 minutes, etc., and can be arbitrarily set by the user via the operation unit 51.

  In addition, since the workflow is taken over after the reproduction of the moving image data by the reproduction unit 49, the execution control unit 33 reproduces the reproduction parameters for reproducing the execution state of the ultrasonic application program at the time of interruption in the storage step of the moving image data. Store in the parameter database 35. Specifically, it is performed as follows. First, the execution control unit 33 specifies a reproduction parameter for reproducing the execution state of the ultrasonic application program by the execution unit 31 in response to an instruction to interrupt the ultrasonic application program via the operation unit 51. . For example, the execution control unit 33 specifies an image processing parameter by the ultrasonic application program as a reproduction parameter. Then, the execution unit 31 stores the specified reproduction parameter in the reproduction parameter database 35. At this time, the execution unit 31 stores the reproduction parameter in the reproduction parameter database 35 in association with the identification information of the workflow to which the ultrasonic application program belongs.

  Next, the reproduction stage of moving image data will be described. FIG. 3 is a diagram showing an example of an initial display screen I1 of the ultrasonic application program in the reproduction stage of moving image data. As shown in FIG. 3, the display screen I1 includes a patient information display area R1 in which patient information is displayed, an image display area R2 in which an ultrasound image I2 and various parameters related thereto are displayed, and buttons for image processing. It has a first button display area R3 in which groups are displayed. Furthermore, the display screen I1 has a thumbnail display area R4 on which a reduced image I3 called a thumbnail is displayed at the lower part of the image display area R1, and a button group for playback operation is displayed on the left side of the thumbnail display area R4. It has a two-button display area R5. As described above, the reduced image I3 is an image representing the operation information, and the display screen at the end of the workflow related to the operation information is reduced. That is, the reduced image I3 is generated for each operation information, that is, for each workflow. The reduced image I3 is stored in the operation information database 39 in association with the moving image data. In the second button display area R5, a button B1, a playback button B2, a stop button B3, a rewind button B4, a fast forward button B5, and the like for setting the playback speed of the moving image are displayed. The arrow A1 is a mouse cursor.

  When taking over the workflow, the user selects a reduced image I3 corresponding to the workflow to be taken over from among the reduced images I3 in the thumbnail display region R4. When the reduced image I3 is selected by the user via the operation unit 51, the reproduction unit 49 starts reproduction of moving image data corresponding to the selected reduced image I3. More specifically, the playback unit 49 searches the operation information database 39 using the operation identification number associated with the selected reduced image I3 as a key, and identifies the moving image data associated with the operation identification number used as the key. Then, the playback unit 49 reads the identified moving image data from the operation information database 39 and causes the display unit 53 to display it.

  FIG. 4 is a diagram illustrating an example of the display screen I4 of the ultrasonic application program related to the reproduction of moving image data. As shown in FIG. 4, when a reduced image is selected, a moving image corresponding to the selected reduced image is reproduced on the display. In this way, by observing the moving image related to the workflow execution, specifically, the movement of the mouse cursor A2 and the ultrasonic image I2, the user can clearly see what processing the user or others have done in the past. The video stops when it is played back until the end of the played video, that is, until the end of the workflow.

  Note that the playback unit 49 does not need to play back the entire video from the beginning to the end. The moving image playback range can be set for the last several minutes, from login to logout, from the beginning to the end of the workflow, between the time points specified by the user, between bookmark points, and the like.

  In addition, the moving image playback speed can be set by operating the button B11 via the operation unit 51 at an actual speed, fast forward, frame advance, or the like. When the mouse cursor A1 is operated via the operation unit 51 and the button B3 is pressed, the reproduction unit 49 stops the moving image being reproduced. When the mouse cursor A1 is operated via the operation unit 51 and the button B2 is pressed while the moving image is stopped, the reproducing unit 49 resumes the reproduction of the stopped moving image. In addition, during playback of a moving image, the playback unit 49 rewinds the moving image when the mouse cursor A1 is operated via the operation unit 51 and the button B3 is pressed, and the moving image is fast-forwarded when the button B4 is pressed.

  As a method for displaying a moving image, the moving image is displayed on the entire screen of the display or displayed in a separate window. Further, the moving image may be displayed only in the image display region R2.

  The information handled by the medical information processing system 1 in the hospital includes patient information. Therefore, care must be taken in handling patient information when taking over the workflow. The user authority management unit 43 can display or hide patient information according to the user who has requested the reproduction of the moving image. Specifically, the user authority management unit 43 performs user authentication based on user identification information input via the operation unit 51 at the time of login or the like. Next, when the reduced image I3, that is, moving image data is selected by the user via the operation unit 51, the user identification information is associated with the selected moving image data as a reproduction non-permitted object or a reproduction permitted object on the operation information database. It is determined whether or not.

  When it is associated as a reproduction non-permission object or when it is not associated as a reproduction permission object, the user authority management unit 43 supplies a non-permission signal indicating that patient information should not be displayed to the reproduction unit 49. As shown in FIG. 4, the playback unit 49 that has received the non-permission signal displays the patient information display region R1 in black or the like to make the patient information invisible to the user.

  On the other hand, when it is not associated with the reproduction non-permission target or when it is associated with the reproduction permission target, the user authority management unit 43 supplies the reproduction unit 49 with a permission signal indicating that the patient information may be displayed. Receiving the supply of the permission signal, the reproducing unit 49 displays the patient information display area R1 as usual, thereby enabling the patient information to be visually recognized by the user.

  When the moving image data is reproduced, the user takes over the workflow. Therefore, the execution control unit 33 controls the execution unit 31 to reproduce the execution state of the ultrasonic application program at the time of interruption. Specifically, the execution control unit 33 searches the reproduction parameter database 35 using the workflow identification information input via the operation unit 51 at the time of login or the like as a key, and identifies the reproduction parameter associated with the key. . Then, the execution control unit 33 reads the specified reproduction parameter from the reproduction parameter database 35 in order to reproduce the execution state of the ultrasonic application program at the time of interruption, and controls the execution unit 31 according to the reproduction parameter. As a result, the execution unit 31 holds the ultrasonic application program in a state where it can be taken over. For example, when the reproduction of the moving image data by the reproduction unit 49 is completed, the display screen of the ultrasonic application program at the time of interruption is displayed on the display unit 53. Then, the execution control unit 33 controls the execution unit 31 in order to resume the execution of the ultrasonic application program from the time of interruption according to the user operation via the operation unit 51. Thereby, the handover of the workflow is completed.

(When operation information is operation log)
Next, an operation example of the medical information processing system 1 when the operation information is an operation log will be described. In the following description, the same portions as the operation when the operation information is moving image data will be redundantly described only when necessary.

  When the reduced image is selected by the user via the operation unit 51, the reproduction unit 49 starts reproducing the user operation when the past ultrasonic application program is executed according to the operation log corresponding to the selected reduced image. To do. More specifically, the playback unit 49 searches the operation information database 339 using the operation identification number associated with the selected reduced image as a key, and identifies the operation log associated with the operation identification number used as the key. Then, the reproducing unit 49 reads the identified operation log from the operation information database 39, and generates display screen data according to the read operation log. Then, the generated display screen data is supplied to the client device 5 via the network, and the moving image is displayed on the display. The video stops when it is played to the end of the operation log.

  The processing result storage unit 45 is generated by the image processing in the operation log related to the execution instruction of the image processing in accordance with the instruction through the operation unit 51 by the user in order to omit the reproduction such as image processing that takes a long time for reproduction. The processed image data is associated and stored in the processing result database 47. When the processing image data is associated with the operation log, the reproducing unit 49 reads the processing image from the processing result database 47 and displays it on the display. At the same time, the reproducing unit 49 skips the operation log related to the image processing, and reproduces the user operation according to the operation log again from the end of the image processing.

  Storing the operation log requires less storage capacity than storing moving image data. Further, by combining the operation log and the snapshot, it is not necessary to spend a long time for reproducing the image processing. When an operation log is stored as operation information, a character string of the operation log may be displayed.

  With the above configuration, the medical information processing system 1 according to the present embodiment records user operations at the time of executing an application program executed in the past as operation information, and reproduces the operation information on the display when taking over the workflow. As a result, the user who takes over the workflow can understand at a glance what kind of processing has been performed in the previous stage and how far it has been executed. Therefore, it is possible to smoothly take over the workflow regardless of whether it is the own workflow or the workflow of another person. Further, even when the work is interrupted in the middle, it is possible to easily resume the work by reproducing the operation information related to before the interruption. Thus, the medical information processing system 1 according to the present embodiment enables efficient handover of the workflow.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.

  As described above, according to the present invention, it is possible to provide a medical information processing system that enables efficient handover of a workflow.
