In the data table 112T, each selected first object Ob1 and each process executed by the first controller 11 are associated with each other. In this way, by referring to the data table 112T, the first controller 11 is configured to be able to execute, for the medical device 10, a process associated with the selected first object Ob1. Note that the association between each first object Ob1 and a process is not limited to that provided by the data table 112T.

Next, details of the configuration of the terminal 20 will be explained. FIG. 5 is a diagram illustrating an example of the hardware configuration of a terminal in an embodiment of the present disclosure. As shown in FIG. 5, the terminal 20 includes a second controller 21, a second display 22, a terminal input section 23, and a transmitting/receiving section 24. The second controller 21 can control the terminal 20 using predetermined software described later.

The second controller 21 has a processor 211, a memory 212, and a real-time clock 213. The second controller 21 controls the overall operation of the terminal 20. For example, the processor 211 controls the operation of the terminal 20 by executing a program such as web browser software stored in the memory 212. The transceiver 24 includes a wired or wireless communication device for connecting to the network 5. The second controller 21 communicates with other devices connected to the network 5 via the transceiver 24.

When the terminal 20 is a tablet personal computer or a smartphone, the terminal input unit 23 is a touch panel. In the following description of the embodiment, the terminal input unit 23 is a touch panel, but the terminal input unit 23 may be, for example, a mouse. The terminal input unit 23 (touch panel) is installed so as to be superimposed on the second display 22. In other words, the terminal input unit 23 and the second display 22 form a touch screen.

Hereinafter, remote monitoring of the medical device 10 by the terminal 20 in the medical system 1 according to an embodiment of the present disclosure will be described. The medical system 1 according to the present embodiment can display on the terminal 20 an image that is substantially the same as the first image 1G displayed on the first display 12 of the medical device 10. As a result, as shown in FIG. 1, for example, the condition of a patient being treated who is connected to the medical device 10 in a room, ICU, etc. in the hospital 9 can be checked in another room (for example, a nurse's station) in the hospital 9. This can be confirmed by the first terminal 20A and the second terminal 20B. Furthermore, in this embodiment, the condition of the patient can be checked from the home of a medical worker such as a doctor on the third terminal 20C.

FIG. 6 is a flowchart illustrating a process in which the terminal displays an image that is substantially the same as the first image displayed on the first display of the medical device according to an embodiment of the present disclosure. First, the operator of the terminal 20 inputs a predetermined URL into the terminal 20, for example. Thereby, the terminal 20 uses predetermined software (Web browser software) to request connection to the server 30 via the network 5 using a predetermined communication protocol (step S11). The communication protocol in this embodiment is, for example, HTTP, but is not limited to this.

The server 30 performs a predetermined authentication on the terminal 20 before the terminal 20 transmits and receives predetermined data to and from the medical device 10 via the network 5. This improves the security of the treatment information stored in the medical device 10. Specifically, when the server 30 receives a connection request from the terminal 20 in step S11, the terminal 20 transmits a predetermined authentication request. More specifically, the server 30 transmits to the terminal 20 a program for causing the above-mentioned predetermined software of the terminal 20 to display a password entry screen. The terminal 20 receives this authentication request (the program for displaying the password entry screen) (step S12).

FIG. 7 is a diagram schematically showing the transition of screens displayed on the second display of the terminal according to an embodiment of the present disclosure. As shown in FIG. 7, upon receiving the authentication request, the terminal 20 (second controller 21) displays a password input screen on the second display 22. When the operator of the terminal 20 inputs a predetermined password using the terminal input section 23 (touch panel) and confirms it by selecting a predetermined object, the terminal 20 inputs the authentication data (i.e., the contents of the password). It is transmitted to the server 30 (step S13). The server 30 determines whether the received authentication data is correct or incorrect.

When the server 30 determines that the authentication data received from the terminal 20 is positive, the server 30 sends the first medical device 10A, the second medical device 10B, the third medical device 10C, and the fourth medical device to the terminal 20. Data for selecting from which of the medical devices 10D the second image data (details will be described later) is transmitted. Specifically, the server 30 transmits to the terminal 20 image data and a program for causing the predetermined software of the terminal 20 to display a medical device selection screen. Then, as shown in FIGS. 6 and 7, the terminal 20 (second controller 21) displays a medical device selection screen on the second display 22 based on this image data and program (step S14). When the operator of the terminal 20 selects a desired medical device 10 on the medical device selection screen displayed on the second display 22, the terminal 20 connects to the selected medical device 10 via the network 5 and selects the selected medical device 10. 10 for the second image data (step S15).

The first controller 11 generates second image data for displaying on the terminal 20 an image that is substantially the same as the displayed first image 1G (see FIG. 3) in response to a request received from the terminal 20. do. The first controller 11 transmits the generated second image data to the terminal 20 via the network 5. In this way, the information obtained from the first image 1G displayed on the first display 12 is not raw data such as the pressure value of the pressure gauge 14 or the set flow rate value of the pump 15, but is obtained from the medical device 10 as image data. It is transmitted to the terminal 20.

As shown in FIGS. 6 and 7, upon receiving the second image data, the terminal 20 displays a second image 2G based on the second image data (step S16). In this way, since the terminal 20 displays the second image 2G based on the second image data rather than the raw data, the integrity of the information that the operator of the terminal 20 can obtain from the displayed second image 2G is limited. It's improving. As a result, the terminal 20 can display an image that is substantially the same as the first image 1G displayed on the medical device 10.

Note that images that are substantially the same as the first image 1G include images that are expressed identically to the first image 1G, as well as images that are compared with the first image data for displaying the first image 1G. The image displayed based on the second image data whose data capacity has been compressed, or one of these images, is enlarged or reduced in size by the terminal 20 according to the size of the second display 22 of the terminal 20. It can be any image.

Further, the second display 22 displays a second image using web browser software. Therefore, no dedicated software is required to confirm the treatment information acquired by the medical device 10 on the terminal 20. Therefore, convenience for the user using the terminal 20 is improved.

Further, the first controller 11 generates second image data at predetermined time intervals and transmits the second image data to the terminal 20 via the network 5. This improves the real-time nature of treatment information obtained by the medical device 10 at the terminal 20.

Specifically, the terminal 20 that displayed the second image 2G based on the second image data in step S16 determines whether or not the second display 22 is displaying the second image 2G ( Step S17). If the second display 22 is already not displaying the second image 2G (NO in step S17), the terminal 20 may end the process without requesting the second image data. If the terminal 20 is displaying the second image 2G (YES in step S17), the terminal 20 displays the latest second image 2G based on the program received together with the second image data. It is confirmed whether a predetermined time has passed since the start (step S18). If the predetermined time has not elapsed since the start of displaying the latest second image 2G (NO in step S18), the processes in steps S17 and S18 are performed again. If a predetermined time has elapsed since the start of displaying the latest second image 2G (YES in step S18), the terminal 20 requests the medical device 10 for second image data again (step S19). The first controller 11 of the medical device 10 generates second image data again in response to the request received from the terminal 20. The first controller 11 transmits the generated second image data to the terminal 20 via the network 5. Then, the terminal 20 performs the process of step S16 again. As a result, the terminal 20 can display the second image 2G as substantially the same image as the latest first image 1G at predetermined time intervals.

Next, remote operation of the medical device 10 by the terminal 20 in the medical system 1 according to an embodiment of the present disclosure will be described. The medical system 1 according to this embodiment can control the medical device 10 from the terminal 20 via the network 5 while displaying the second image 2G. For example, when a warning display screen is displayed as the first image 1G on the medical device 10 as shown in FIG. 3, the operator of the terminal 20 can cancel the warning or transition to a different screen using the terminal 20.

As shown in FIG. 7, the terminal input unit 23 (touch panel) receives user input based on the displayed second image 2G. Specifically, the user input is selection of the position 2P on the displayed second image 2G. That is, the user input is a touch on the touch panel, which is the terminal input section 23, at position 2P. The second controller 21 transmits input data based on user input to the medical device 10. The input data are coordinate values indicating the position 2P on the second image 2G.

FIG. 8 is a flowchart illustrating a process flow in which a medical device according to an embodiment of the present disclosure controls the medical device based on data received from a terminal. As shown in FIG. 8, the first controller 11 of the medical device 10 controls the medical device 10 based on input data (coordinate values) received from the terminal 20. In this way, the operator of the terminal 20 can remotely control the medical device 10 via the network using the terminal 20 based on the information obtained from the second image 2G using the terminal 20. Specifically, the first controller 11 determines which second object Ob2 has been selected among the plurality of second objects Ob2 included in the second image 2G based on the received coordinate values (step S21). , executes the process associated with the selected second object Ob2 on the medical device 10 (step S23). Therefore, the operator of the terminal 20 can intuitively operate the medical device 10 from the terminal 20 based on the information obtained from the second image 2G.

Note that, as shown in FIG. 4, in the data table 112T stored in the memory 112 of the first controller 11, selection of each second object Ob2 corresponds to selection of each first object Ob1 and each process of the medical device 10. are associated with each other. The selection of each second object Ob2 may be associated only with the selection of each first object Ob1, or may be associated only with each process of the medical device 10.

Note that immediately after executing the process in step S23 shown in FIG. 8, the terminal 20 may further request the medical device 10 to transmit the second image data. Thereby, the terminal 20 can receive the latest second image data without waiting for the second image data transmission request in step S19 shown in FIG. As a result, the real-time performance of remote control of the terminal 20 is improved.

Further, as shown in FIG. 4, at least some of the processes of the first controller 11 associated with the first object Ob1 can be set so that they cannot be executed by selecting the second object Ob2. be. Thereby, for example, processing that is considered undesirable as remote control from the terminal 20 can be prevented from being executed from the terminal 20.

In this embodiment, as shown in FIG. 4, the data table 112T includes data for determining whether the processor 111 executes the process associated with the selection of the second object Ob2. In the example of the data table 112T, the setting is such that the process of changing the set value of the flow rate of the pump 15 cannot be executed by selecting the second object Ob2. Furthermore, the medical device 10 may be configured such that the operator of the medical device 10 can switch whether or not to execute a plurality of processes corresponding to the selection of each first object Ob1 by selecting the second object Ob2. .

Further, as shown in FIG. 8, after the process of step S21 and before the process of step S23, the first controller 11 determines whether or not it is okay to execute the process by selecting the second object Ob2. is determined based on the data table 112T (step S22). If the first controller 11 determines that the process can be executed (YES in step S22), it executes the process in step S23. If the first controller 11 determines not to execute the process (NO in step S22), the first controller 11 does not execute the process in step S23. When the first controller 11 does not execute the process of step S23, the first controller 11 may display a message to that effect on the first display 12.

As described above, the medical system 1 according to this embodiment includes the medical device 10 and the terminal 20. The terminal 20 is capable of transmitting and receiving predetermined data to and from the medical device 10 via the network 5. Medical device 10 includes a first controller 11 and a first display 12 . The first controller 11 generates first image data based on treatment information acquired by the medical device 10. The first display 12 displays a first image 1G based on the first image data. The first controller 11 generates second image data for displaying on the terminal 20 an image that is substantially the same as the displayed first image 1G, and generates second image data in response to a request received from the terminal 20. The data is transmitted to the terminal 20 via the network 5. Upon receiving the second image data, the terminal 20 displays a second image 2G based on the second image data.

According to the above configuration, since the medical device 10 transmits the information obtained from the first image 1G displayed on the first display 12 to the terminal 20 as image data rather than raw data, the information is displayed on the terminal 20. The integrity of information obtained by the second image 2G can be improved.
