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

  FIG. 1 is a configuration diagram showing the overall configuration of the dialysis management system of the present embodiment. The dialysis management system of this embodiment includes a terminal 1 (blood pressure data display terminal) used by medical staff (for example, doctors, nurses, etc.) and a server 2. It is assumed that the terminal 1 and the server 2 can communicate via a wireless network or a wired network.

  The terminal 1 is a device that displays patient data. As the terminal 1, a communication device (mobile terminal) such as a tablet terminal or a smartphone can be used. The terminal 1 illustrated includes an acquisition unit 11, a detection unit 12, a generation unit 13, and a storage unit 14.

  The acquisition unit 11 receives the patient ID input by the medical staff, and acquires dialysis data indicating the state of the patient corresponding to the input patient ID from the server 2. In the present embodiment, the acquisition unit 11 acquires, as dialysis data, blood pressure data indicating a time-series blood pressure value of a patient during dialysis treatment from the server 2 for a predetermined period. The blood pressure data is data indicating the transition of blood pressure values measured from the start to the end of dialysis treatment.

  In addition, the acquisition unit 11 includes, as dialysis data, pulse data indicating the time-series pulse of the patient during dialysis treatment and integrated water removal data indicating the time-series integrated water removal amount during the dialysis treatment for a predetermined period. Or from the server.

  The detection unit 12 detects a change in the screen orientation of the terminal 1. For example, the detection unit 12 detects a change in the orientation (tilt) of the screen of the terminal 1 using an acceleration sensor, a geomagnetic sensor, or the like. That is, an operation in which the medical staff tilts the terminal 1 (tilts the screen of the terminal 1 from portrait (portrait) to landscape (landscape) or from landscape to portrait) is detected.

  The generation unit 13 generates a three-dimensional graph (3D graph) using the dialysis data for a predetermined period acquired from the server 2. In this embodiment, the production | generation part 13 produces | generates the three-dimensional graph expressed in three dimensions of the dialysis date and time, the elapsed time from the start of dialysis, and a blood pressure value using the blood pressure data of a predetermined period. Moreover, the production | generation part 13 may produce | generate a three-dimensional graph similarly to blood pressure data also about the pulse data and integrated water removal data of a predetermined period. In the present embodiment, when the detection unit 12 detects a change in the orientation of the screen, the generation unit 13 generates a three-dimensional graph. However, the present invention is not limited to this.

  The storage unit 14 stores dialysis data for a predetermined period acquired from the server 2.

  The server 2 of this embodiment includes a control unit 21 and a patient DB (database) 22. The control unit 21 receives a data request including a patient ID from the terminal 1, reads out patient dialysis data corresponding to the patient ID from the patient DB 22 for a predetermined period, and transmits the data to the requesting terminal 1.

  In the patient DB 22, for each patient ID, dialysis data at the time of dialysis treatment of each patient is stored as history information together with the dialysis date and the dialysis elapsed time (or measurement time).

  As the terminal 1 and the server 2 described above, for example, a general-purpose computer system including a CPU, a memory, an external storage device such as a hard disk, an input device, and an output device can be used. In this computer system, each function of each device is realized by the CPU executing a predetermined program loaded on the memory. For example, each function of the terminal 1 and the server 2 is realized by executing the CPU of the terminal 1 in the case of the program for the terminal 1, and the CPU of the server 2 in the case of the program for the server 2.

  Further, the program for the terminal 1 and the program for the server 2 can be stored in a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, a DVD-ROM, or distributed via a network. You can also.

  Next, operation | movement of the dialysis management system of this embodiment is demonstrated.

  FIG. 2 is a sequence diagram showing the operation of the dialysis management system. The acquisition unit 11 of the terminal 1 transmits a data acquisition request including a patient ID (patient identification information) to the server 2 (S11). For example, the acquisition unit 11 receives a patient ID input by a medical staff and transmits a data acquisition request including the patient ID. Moreover, the acquisition part 11 is good also as acquiring patient ID by another method and transmitting a data acquisition request.

  When receiving the data acquisition request transmitted from the terminal 1, the control unit 21 of the server 2 reads out dialysis data corresponding to the patient ID included in the data acquisition request from the patient DB 22 for a predetermined period (S12), The read dialysis data is transmitted to the requesting terminal 1 (S13). The dialysis data for a predetermined period is dialysis data that goes back a predetermined period (for example, one month) from the latest dialysis date. The dialysis data for a predetermined period may be dialysis data for a predetermined number of times (for example, 10 times) retroactively from the latest dialysis treatment.

  The dialysis data includes, for example, blood pressure data indicating a time-series blood pressure value (change in blood pressure value) for each dialysis treatment, pulse data indicating a time-series pulse, and integrated water removal indicating a time-series integrated water removal amount. Data. The control unit 21 also reads out patient data such as the patient's name and treatment-related data (instruction basic information, equipment data, drug data, etc.) in the latest dialysis treatment from the patient DB 22 and transmits it to the terminal 1. To do.

  The generation unit 13 of the terminal 1 receives dialysis data, patient data, and treatment-related data, and stores the received data in the storage unit 14. And the production | generation part 13 produces | generates a top screen using the patient data and treatment related data which were received from the server 2, and displays it on the display with which the terminal 1 is provided (S14).

  FIG. 3 is a diagram illustrating an example of a top screen displayed on the display of the terminal 1. The illustrated top screen displays the name of the patient ID transmitted in S11 and the treatment related data of the latest dialysis date and time of the patient.

  And the production | generation part 13 of the terminal 1 will produce | generate a two-dimensional graph (2D graph) using the dialysis data of the newest dialysis date, if the operation of the graph display instruction | indication of a medical staff is received (S15), and displays it on a display. (S16). For example, on the top screen shown in FIG. 3, it is assumed that the user touches (tap) the button “go to graph display” 31 by the medical staff, and a generation instruction for a two-dimensional graph is input to the terminal 1.

  FIG. 4 is a diagram illustrating an example of a two-dimensional graph screen displayed on the display of the terminal 1. In the illustrated two-dimensional graph screen, a part of information (name, part of treatment-related data) on the top screen shown in FIG. 3 and a two-dimensional graph 41 of dialysis data of the latest dialysis date and time are displayed.

  The two-dimensional graph 41 shown in the figure shows a two-dimensional graph of blood pressure data, pulse data, and integrated water removal data at the latest dialysis date. The blood pressure data includes two two-dimensional graphs of systolic blood pressure values (high blood pressure) and diastolic blood pressure values (low blood pressure).

  The horizontal axis of the two-dimensional graph is the elapsed time (or measurement time) from the start of dialysis, and the vertical axis shows the value of each data (blood pressure data, pulse data, and integrated water removal data). . The blood pressure data and the pulse data are time-series data in which the measurement timing and the measurement values when the medical staff measures the blood pressure and the pulse are associated with each other. As the measurement timing, the elapsed time from the start of dialysis treatment or the measurement time when the medical staff measures blood pressure and pulse is used. The medical staff measures the blood pressure and pulse of the patient at an arbitrary measurement timing, and registers the measurement result in the patient DB 22 of the server 2 using the terminal 1 or the like. The generation unit 13 generates a two-dimensional graph by connecting time series measurement values of blood pressure data and pulse data with a straight line.

  The integrated water removal data is measured by a dialysis machine (not shown) at a predetermined timing (for example, every 10 minutes) and registered in the patient DB 22 of the server 2. The production | generation part 13 produces | generates a two-dimensional graph by connecting the measurement value of time series of integrated dewatering data with a straight line.

  In FIG. 4, four graphs of blood pressure data (systolic blood pressure value, diastolic blood pressure value), pulse data, and integrated water removal data are displayed. The medical staff touches the check box 42 to check it. The medical staff can display only a two-dimensional graph of desired data (for example, only blood pressure data).

  And the production | generation part 13 of the terminal 1 will receive the dialysis data of the newest dialysis date, when operation of the medical staff's three-dimensional graph display instruction | indication is received in the state in which the two-dimensional graph screen shown in FIG. 4 was displayed (S17). A three-dimensional graph is generated using the dialysis data for a predetermined period including the data and displayed on the display (S18).

  In the present embodiment, it is assumed that a medical staff inputs an instruction to generate a three-dimensional graph to the terminal 1 by performing an operation of tilting the screen of the terminal 1 from portrait (vertically long) to landscape (landscape). The detection unit 12 detects a change in the screen orientation (tilt) of the terminal 1 (change from vertical to horizontal) and notifies the generation unit 13 that a three-dimensional graph display instruction has been input. In the state where the top screen shown in FIG. 3 and the two-dimensional graph screen shown in FIG. 4 are displayed, it is assumed that the medical staff holds the screen of the terminal 1 in a portrait orientation (portrait).

  In this embodiment, the medical staff inputs the 3D graph display instruction by changing the orientation of the terminal 1, but the 3D graph display instruction may be input by any other method. . For example, a button “To 3D graph display” (not shown) is displayed on the 2D graph screen shown in FIG. 4, and the user touches the button to input a 3D graph display instruction to the terminal 1. You may be made to do.

  FIG. 5 is a diagram illustrating an example of a three-dimensional graph screen displayed on the display of the terminal 1. The illustrated three-dimensional graph screen displays a part of information on the top screen shown in FIG. 3 and a three-dimensional graph 51 of blood pressure data (systolic blood pressure value (high blood pressure)).

  The generation unit 13 uses a blood pressure data of a predetermined period from the latest dialysis date acquired from the server 2 to generate a three-dimensional graph of blood pressure data expressed in three dimensions: dialysis date and time, elapsed time from the start of dialysis, and blood pressure value. Generate.

  In the example shown in FIG. 5, the generation unit 13 has the blood pressure value on the vertical axis (X axis) indicating the vertical direction, the elapsed time from the start of dialysis on the horizontal axis (Y axis) indicating the horizontal direction, and the depth axis indicating the depth direction. The dialysis date and time is set on (Z axis). In addition, for the dialysis date on the depth axis, the generation unit 13 generates a three-dimensional graph so that blood pressure data of the latest dialysis date is in front of the user and goes back as it goes back in the past. In the example of the three-dimensional graph shown in FIG. 5, for the elapsed time from the start of dialysis, the measurement time when the blood pressure is measured by the medical staff in the latest dialysis treatment is set.

  6 to 9 show a procedure for generating a three-dimensional graph. First, as illustrated in FIG. 6A, the generation unit 13 plots (sets) each dialysis date on the depth axis of the three-dimensional graph so that the dialysis date is nearer to the front than the present and goes back to the past. ) In the examples shown in FIGS. 6 to 9, “◯” represents today's blood data, “Δ” represents blood data two days ago, and “□” represents blood data four days ago. In the example shown in FIG. 6A, the blood pressure value at the start of dialysis is “0” at all dialysis dates. FIG. 6B is an image view of the graph shown in FIG. FIG.6 (c) is the image figure which looked at the graph shown to Fig.6 (a) from the top.

  Next, as shown to Fig.7 (a), the production | generation part 13 plots the blood pressure data of each dialysis date on a three-dimensional graph. In addition, when each blood pressure value of the blood pressure data is associated with the measurement time, the generation unit 13 converts the measurement time into an elapsed time from the start of dialysis and plots it on a three-dimensional graph. FIG. 7B is an image view of the graph shown in FIG. FIG.7 (c) is the image figure which looked at the graph shown to Fig.7 (a) from the top.

  Next, as shown to Fig.8 (a), the production | generation part 13 covers the mesh 81 from the top of the graph of Fig.7 (a) which plotted the blood pressure data, in order to produce | generate a surface. FIG. 8B is an image view of the graph shown in FIG.

  Thereby, as shown to Fig.9 (a), the surface (inclined surface) of the mesh 81 is formed, and when it plots, an unevenness | corrugation is made. Then, the generation unit 13 generates a shadow as illustrated in FIG. 5 by applying light to the three-dimensional graph of FIG. 9A covered with the mesh 81. From this shadow, the human eye recognizes that the graph is three-dimensional.

  Moreover, the production | generation part 13 is good also as producing | generating the three-dimensional graph which adjusted the color shading (lightness, saturation, etc.) according to the blood-pressure value. For example, the generation unit 13 may generate the three-dimensional graph colored with a predetermined color so that the higher the blood pressure value is, the darker the color is, and the lower the blood pressure value is, the lighter color is changed.

  By generating a three-dimensional graph according to the procedure described with reference to FIGS. 6 to 9, the measurement timing of the medical staff is an arbitrary timing, the measurement timing at the past dialysis treatment, and the measurement at the latest dialysis treatment Even when the timing is different (when they are not aligned), a three-dimensional graph can be easily created.

  The three-dimensional graph shown in FIG. 5 is a graph of systolic blood pressure value (blood pressure high), but when the medical staff touches one of the radio buttons 52 shown in FIG. An instruction to generate another three-dimensional graph (diastolic blood pressure value, pulse, integrated water removal) is received, and a three-dimensional graph of other touched data is generated and displayed in the same manner as the three-dimensional graph shown in FIG.

  When the medical staff wants to return to the two-dimensional graph screen shown in FIG. 4 while the three-dimensional graph screen shown in FIG. 5 is displayed, the medical staff changes the screen of the terminal 1 from landscape (landscape) to portrait (portrait). It is assumed that a two-dimensional graph display instruction is input to the terminal 1 by performing the tilting operation. The detection unit 12 detects a change in the orientation (tilt) of the screen of the terminal 1 (change from horizontal to vertical), and notifies the generation unit 13 that a two-dimensional graph display instruction has been input. Thereby, the production | generation part 13 performs the process of S16, produces | generates and displays the two-dimensional graph screen shown in FIG.

  In the present embodiment, the medical staff performs an operation of tilting the screen of the terminal 1 from portrait (vertically long) to landscape (landscape) to change from the two-dimensional graph screen shown in FIG. 4 to the three-dimensional graph screen shown in FIG. In addition, the medical staff performs an operation of tilting the screen of the terminal 1 from horizontal (horizontal) to vertical (vertical), so that the three-dimensional graph screen shown in FIG. 5 changes to the two-dimensional graph screen shown in FIG. However, the screen transition of the two-dimensional graph screen and the three-dimensional graph screen is not limited to the above operation. For example, by performing an operation of tilting the screen from landscape (landscape) to portrait (portrait), the screen transitions from a 2D graph screen to a 3D graph screen and performs an operation of tilting from portrait (vertically) to landscape (landscape). Thus, the transition from the three-dimensional graph screen to the two-dimensional graph screen may be performed.

  In the terminal 1 of the present embodiment described above, blood pressure data indicating a time-series blood pressure value of the patient during dialysis treatment is acquired from the server 2 for a predetermined period, and dialysis is performed using the acquired blood pressure data. A three-dimensional graph expressed in three dimensions of date and time, elapsed time from the start of dialysis, and blood pressure value is generated and displayed.

  Thereby, in this embodiment, in dialysis treatment, the transition of the patient's state from the past can be easily grasped, and the work load on the medical staff can be reduced. Specifically, when a medical staff wants to know the blood pressure status of a patient during multiple dialysis treatments going back in the past, a single three-dimensional graph can be displayed without calling up and displaying multiple screens for each dialysis treatment. It is possible to easily grasp the transition of the patient's blood pressure from the past simply by displaying. That is, in the present embodiment, blood pressure data for a predetermined period can be viewed and confirmed by expressing the blood pressure data in a three-dimensional graph.

  Moreover, in this embodiment, the relationship with the information at the time of the past dialysis treatment can be easily grasped by expressing it by a three-dimensional graph. For example, the blood pressure is measured 1 hour after the start of dialysis treatment each time. Significant patient signs such as a drop can be easily detected. In addition, by displaying a three-dimensional graph of a predetermined period, it is possible to take a view that is not trapped by exceptional blood pressure values (outliers).

  Moreover, in this embodiment, by expressing it with a three-dimensional graph, even if blood pressure data is similar to past blood pressure data, it is difficult for line overlap to occur and an easy-to-read graph can be displayed.

  In the present embodiment, the display instruction of the three-dimensional graph screen is detected by performing an operation of tilting (rotating) the screen of the terminal 1. Thereby, since the medical staff can display a three-dimensional graph screen by a simple operation, the convenience of the medical staff can be improved.

  While the embodiments of the present invention have been described above, various modifications and changes can be made to the embodiments of the present invention without departing from the spirit of the present invention.
