[0003] [Patent Document 1] Special Publication No. 2021-533599 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-described technology, the viewing device acquires and displays the electronic medical record as an image file. Because the electronic medical record is an image file, it is difficult for a user to operate the viewing device and update the electronic medical record stored in the device (hereinafter sometimes referred to as the electronic medical record device) in which the electronic medical record is stored. However, visiting a medical facility where an electronic medical record device is located just to update the electronic medical record is time-consuming, and there has been a demand for updating the electronic medical record from a remote location.

[0005] The present invention has been made in consideration of the above-mentioned points, and has an object to provide a technique for suitably updating electronic medical records. [Means for solving the problem]

[0006] One aspect of the present invention is a remote control device comprising: a receiving unit that receives operation instructions from an external computer device via a network; an operation instruction output unit that outputs the received operation instructions to an operation instruction receiving unit of a computer device to be operated via a first line for operation; an image signal receiving unit that receives, via a second line for image output, an image signal that the computer device to be operated outputs based on the operation instructions; and an image signal transmitting unit that transmits the received image signal to the external computer device via the network.

[0007] In one aspect of the present invention, the network is a virtual private network.

[0008] In one aspect of the present invention, the first line is a universal serial bus (USB).

[0009] In one aspect of the present invention, the second line is a high-definition multimedia interface (HDMI (registered trademark)). [Effects of the Invention]

[0010] According to the present invention, electronic medical records can be updated in an optimal manner. [Brief explanation of the drawings]

[Figure 4] 1 is a block diagram showing an example of an internal configuration of a remote control device according to an embodiment of the present invention; [Figure 5] FIG. 1 is a block diagram showing an example of a conventional system 9 for sharing information on electronic medical records held by hospitals in remote locations. DETAILED DESCRIPTION OF THE INVENTION

[0012] [Example of conventional technology] First, an example of the prior art will be briefly described with reference to FIG.

[0013] Fig. 5 is a diagram showing an example of a conventional system 9 for sharing information on electronic medical records held by remote hospitals. The conventional system 9 includes a viewing device 91, a capture device 92, and multiple electronic medical record devices 93. The viewing device 91 and the capture device 92 are connected via a network NW. The capture device 92 and the multiple electronic medical record devices 93 are also connected via a wired signal line that can communicate image data of the electronic medical records.

[0014] Each electronic medical record device 93 transmits image data of the electronic medical record to the capture device 92. The capture device 92 then transmits the received image data to the viewing device 91. This allows a user operating the viewing device 91 to view the electronic medical record held by the electronic medical record device 93 without having to directly operate the electronic medical record device 93.

[0015] In the conventional system 9, electronic medical record information is transmitted in one direction from the electronic medical record device 93 to the capture device 92. This prevents the electronic medical record information held by each electronic medical record device 93 from being tampered with by malicious users. However, in the conventional system 9, even a doctor or other person who treats a patient has difficulty updating the electronic medical record information held by the electronic medical record device 93 using the capture device 92 or the viewing device 91. The system 1 according to this embodiment solves the above-mentioned problems and allows a user in a remote location to update confidential information held by the computer being operated while ensuring security.

[0016] [Embodiment] A remote control device according to the present embodiment will be described in detail below with reference to the accompanying drawings, showing preferred embodiments. In the drawings, identical or similar parts are designated by identical or similar reference numerals. Note that the present embodiment is not limited to these embodiments and includes various modifications and improvements. In other words, the components described below include those that would be easily conceivable to a person skilled in the art and those that are substantially identical, and the components described below can be combined as appropriate. Furthermore, various omissions, substitutions, or modifications of the components of the present embodiment may be made without departing from the spirit and scope of the present invention.

[0017] First, a system 1 according to an embodiment will be described with reference to Fig. 1. In the system 1 described below, a remote control device is used to view and update (write in) electronic medical records held by a hospital in a remote location.

[0018] Fig. 1 is a block diagram for explaining an example of the configuration of a system 1 according to this embodiment. The system 1 includes a viewing device 10, a remote control device 20, and an electronic medical record device 30. The system 1 in Fig. 1 shows an example in which one viewing device 10, one remote control device 20, and one electronic medical record device 30 are provided, but this embodiment is not limited to this example, and multiple devices of at least one of the viewing device 10, the remote control device 20, and the electronic medical record device 30 may be provided.

[0019] The viewing device 10 and the remote control device 20 are connected via a network NW. The network NW may be a wired network or a wireless network. The network NW is a predetermined communication network configured using lines. The network NW may include, for example, a virtual private network (VPN), a local area network (LAN), a wireless LAN (WLAN), a wide area network (WAN), a wireless WAN (WWAN), a metropolitan area network (MAN), the Internet, a wireless LAN, LTE (Long Term Evolution), etc. The VPN may be, for example, an Internet VPN established using an Internet line, or an IP-VPN (Internet Protocol-Virtual Private Network) to which predetermined users can connect.

[0020] The viewing device 10 and the remote control device 20 are each connected to the network NW via a communication device (not shown) located within the facility. The communication device is a device used to connect to the network NW, and may include, for example, a router, an ONU, a modem, etc.

[0021] The remote control device 20 and the electronic medical record device 30 are connected by two types of signal lines capable of transmitting signals and are provided in the same facility. Fig. 1 shows an example in which the viewing device 10 is provided in a first hospital, and the remote control device 20 and the electronic medical record device 30 are provided in a second hospital different from the first hospital. Note that providing the viewing device 10, remote control device 20, and electronic medical record device 30 in a hospital is just an example, and they may also be provided in other facilities (for example, a university hospital).

[0022] The viewing device 10 is an information processing device such as a smartphone, a tablet terminal, or a personal computer. The viewing device 10 is operated by a user in the first hospital. The user is a person who views or updates the electronic medical record, and may include, for example, a doctor or nurse who treats patients at the first hospital, a medical doctor or professor who teaches or researches, or a student who is the subject of education. The user may operate the viewing device 10 by touching a display unit such as a display of the viewing device 10 with a finger or a touch pen, or may operate the viewing device 10 using an input device such as a mouse, keyboard, touch tablet, or microphone. The viewing device 10 may also be referred to as an external computer device.

[0023] The remote control device 20 operates the electronic medical record device 30 based on the operation of the user using the viewing device 10. The remote control device 20 also transmits a signal related to the screen to be displayed on the electronic medical record device 30 to the viewing device 10. Based on the signal transmitted from the remote control device 20, the viewing device 10 displays to the user a screen similar to the screen displayed on the electronic medical record device 30. The user remotely controls the electronic medical record device 30 using the viewing device 10 and the remote control device 20. The remote control device 20 may be, for example, a KVM (Keyboard Video Mouse) switch.

[0024] The electronic medical record device 30 is an information processing device such as a smartphone, tablet terminal, or personal computer. The electronic medical record device 30 is a device that can view and update electronic medical records owned by the second hospital. The electronic medical records show the progress of medical treatment by doctors and others. The electronic medical record device 30 displays a specified electronic medical record using a display means such as a display when specified operations are performed using input devices such as a keyboard or mouse. The electronic medical record device 30 is connected to an electronic medical record network 40. The electronic medical record device 30 extracts and displays a desired electronic medical record from other electronic medical record devices 30 connected to the electronic medical record network 40 or from an electronic medical record storage device (not shown) connected to the electronic medical record network 40. The electronic medical record device 30 may also be referred to as the computer device to be operated.

[0025] The electronic medical record network 40 is a network that connects electronic medical record storage devices and electronic medical record devices 30. Hereinafter, a system having the electronic medical record device 30, the electronic medical record network 40, and the electronic medical record storage device as components will be referred to as the electronic medical record system. The electronic medical record system manages electronic medical records that record the medical treatment process of patients within the second hospital. The electronic medical record system enables the electronic medical records required by the electronic medical record device 30, among those managed within the second hospital, to be viewed and updated on the electronic medical record device 30. The electronic medical record device 30 is not connected to an external network (external line).

[0026] Generally, when remotely operating a device within a closed network, the computer device operated directly by the user and the computer device to be operated are directly connected via a VPN. In this case, the two computers are connected using a LAN cable and can perform network communication, making it possible for a malicious third party to infiltrate the computer device to be operated. In the system 1 according to this embodiment, the LAN cable is used to connect the viewing device 10 to the remote control device 20. In other words, the remote control device 20 and the electronic medical record device 30 cannot perform network communication. Therefore, according to the system 1 according to this embodiment, a malicious third party cannot infiltrate the electronic medical record device 30, which is the computer device to be operated, via the network NW, thereby ensuring security.

[0027] With reference to FIG. 2, the functional configuration of the remote control device 20 and the electronic medical record device 30 according to this embodiment, and the manner in which the remote control device 20 and the electronic medical record device 30 are connected will be specifically described.

[0028] 2 is a block diagram showing an example of the functional configuration of the remote control device 20 and the electronic medical record device 30. The remote control device 20 includes a receiving unit 21, an operation instruction output unit 22, an image signal receiving unit 23, and an image signal transmitting unit 24.

[0029] The electronic medical record device 30 includes an operation instruction receiving unit 31 and an image signal output unit 32.

[0030] Each functional unit of the remote control device 20 and the electronic medical record device 30 is realized, for example, using a computer equipped with a CPU (Central Processing Unit) and memory, and software. Each functional unit may also be realized using electronic circuits as needed. Furthermore, each functional unit does not have to be included in a single device, and the remote control device 20 and the electronic medical record device 30 may be configured from multiple devices.

[0031] First, the first line L1 will be described with reference to the receiving unit 21, the operation instruction output unit 22, and the operation instruction receiving unit 31.

[0032] The receiving unit 21 receives an operation instruction from the viewing device 10 via the network NW. The operation instruction is a signal based on the operation of the viewing device 10 by the user, and is a signal used when the user operates the electronic medical record device 30 (hereinafter, may be referred to as an operation signal OS).

[0033] The operation instruction output unit 22 acquires the operation signal OS from the receiving unit 21. The operation instruction output unit 22 outputs the operation signal OS to the electronic medical record device 30 via the first line L1. If multiple electronic medical record devices 30 are provided in the second hospital, the operation signal OS may be output to a predetermined electronic medical record device 30 or to an electronic medical record device 30 selected by the user operating the viewing device 10.

[0034] The first line L1 transmits an operation signal OS. The first line L1 does not transmit data files. The first line L1 is connected to the remote control device 20 and the electronic medical record device 30. In this embodiment, the operation signal OS is transmitted from the remote control device 20 to the electronic medical record device 30 via the first line L1. In other words, the direction in which signals are communicated on the first line L1 is unidirectional. The communication standard of the first line L1 may be, for example, a universal serial bus (USB). By providing the first line L1, it is possible to "write into the electronic medical record held by the electronic medical record device 30," which was difficult in the conventional system 9, while ensuring security.

[0035] The operation instruction receiving unit 31 receives an operation signal OS from the remote operation device 20 via the first line L1. The electronic medical record device 30 is operated based on the operation signal OS acquired by the operation instruction receiving unit 31. Specifically, the electronic medical record device 30 may display the electronic medical record desired by the user or may add to the electronic medical record in accordance with the operation signal OS.

[0036] Next, the second line L2 will be described with reference to the image signal output unit 32, the image signal receiving unit 23, and the image signal transmitting unit 24.

[0037] The image signal output unit 32 outputs an image signal IS to the remote operation device 20 via the second line L2. The image signal IS is a signal indicating a screen to be displayed on the display means of the electronic medical record device 30. In other words, the electronic medical record device 30 outputs to the remote operation device 20 an image signal IS that can display a screen similar to that of the display means of the electronic medical record device 30.

[0038] The second line L2 is a signal line independent of the first line L1 and transmits an image signal IS. The second line L2 does not transmit data files. The second line L2 is connected to the remote operation device 20 and the electronic medical record device 30. In this embodiment, the image signal IS is transmitted from the electronic medical record device 30 to the remote operation device 20 via the second line L2. In other words, the direction in which signals are communicated on the second line L2 is unidirectional. The second line L2 may be, for example, a high-definition multimedia interface (HDMI (registered trademark)), a DisplayPort (DP), a DVI (Digital Visual Interface), etc.

[0039] The image signal receiving unit 23 receives the image signal IS from the electronic medical record device 30 via the second line L2.

[0040] The image signal transmitting unit 24 acquires the image signal IS from the image signal receiving unit 23. The image signal transmitting unit 24 transmits the image signal IS via the network NW to the viewing device 10 that has transmitted the operation signal OS. The viewing device 10 receives the image signal IS and displays a screen corresponding to the image signal IS. As a result, the viewing device 10 displays a screen similar to the screen displayed on the electronic medical record device 30. According to the system 1, a user can use the viewing device 10 to remotely operate the electronic medical record device 30.

[0041] 3 is a sequence diagram showing an example of the processing flow of each device in the system 1 according to this embodiment. With reference to the diagram, the processing of each of the viewing device 10, the remote control device 20, and the electronic medical record device 30, and the signals transmitted and received between these devices will be described.

[0042] (Step S101) When the remote operation device 20 is started up, the electronic medical record device 30 transmits an image signal IS to the remote operation device 20 via the second line L2. The image signal IS is transmitted in accordance with, for example, the HDMI communication standard.

[0043] (Step S102) The viewing device 10 connects to the network NW using a communication device in the first hospital. The remote operation device 20 connects to the network NW using a communication device in the second hospital. Here, it is assumed that the viewing device 10 has been previously configured to connect to the communication device and the network NW. That is, it is assumed that the viewing device 10 has previously stored in its storage means information for connecting to the communication device and information for connecting to the network NW. It is also assumed that the remote operation device 20, like the viewing device 10, has previously stored in its storage means information for connecting to the communication device and information for connecting to the network NW. This enables the viewing device 10 to communicate with the remote operation device 20 connected to the network NW.

[0044] (Step S103) The viewing device 10 requests the remote control device 20 connected via the network NW to transmit an image signal IS of the electronic medical record device 30. The viewing device 10 may further transmit an identifier capable of identifying each of the multiple viewing devices 10 to the remote control device 20. Note that the user may operate the viewing device 10 to select the electronic medical record device 30 from which the transmission of the image signal IS is requested.

[0045] (Step S104) The remote control device 20 transmits the image signal IS received from the electronic medical record device 30 to the viewing device 10 that has made the transmission request. Note that the remote control device 20 may identify the viewing device 10 that has made the transmission request by using the identifier transmitted together with the transmission request.

[0046] (Step S105) The viewing device 10 receives the image signal IS from the remote control device 20. The viewing device 10 displays a screen based on the received image signal IS on the display means of the viewing device 10. That is, the same screen as the screen displayed on the display means of the electronic medical record device 30 is displayed on the display means of the viewing device 10.

[0047] (Step S106) The viewing device 10 transmits an operation signal OS based on a user's operation using an input device such as a keyboard or a mouse to the remote control device 20 via the network NW.

[0048] (Step S107) The remote control device 20 transmits the received operation signal OS to the electronic medical record device 30 to which the viewing device 10 has requested transmission of the image signal IS. The operation signal OS is transmitted in accordance with, for example, the USB communication standard. The electronic medical record device 30 receives the operation signal OS from the viewing device 10 via the remote control device 20.

[0049] (Step S108) In response to the operation signal OS, the electronic medical record device 30 performs the same processing as when the user directly operates the electronic medical record device 30. The electronic medical record device 30 outputs an image signal IS indicating the output screen after processing in accordance with the operation signal OS to the remote control device 20 in accordance with, for example, the HDMI communication standard.

[0050] (Step S109) The remote operation device 20 receives the image signal IS from the electronic medical record device 30. The remote operation device 20 transmits the received image signal IS to the viewing device 10 that transmitted the operation signal OS.

[0051] (Step S110) The viewing device 10 displays a screen based on the received image signal IS, similar to step S105.

[0052] 3 shows an example of a process flow in which the remote control device 20 transmits an image signal IS to the viewing device 10 when the viewing device 10 requests an image signal IS (step S103) or issues an operation instruction (step S106). This is illustrated to explain the process flow of each device in the system 1. The electronic medical record device 30 according to the embodiment may continuously transmit an image signal IS to the remote control device 20, and the remote control device 20 may continuously transmit the image signal IS received from the electronic medical record device 30 to the viewing device 10.

[0053] By repeatedly performing the processes from step S106 to step S110, the user can operate the electronic medical record device 30 without visiting the second hospital where the electronic medical record device 30 is installed. Specifically, when the user operating the viewing device 10 performs an operation to view the electronic medical record of a desired patient, the electronic medical record is displayed on the display of the viewing device 10, etc.

[0054] In the above description, an example is shown in which the electronic medical record network 40 is a closed network that is not connected to an external network, in order to demonstrate that the electronic medical record device 30 can be operated while ensuring security. However, this embodiment is not limited to this example, and the electronic medical record network 40 may be an open network that is connected to an external network. In other words, with the remote operation device 20 according to this embodiment, a user can remotely operate an information terminal such as the electronic medical record device 30 installed in a remote location, regardless of whether the system is a closed system or an open system.

[0055] In the above description, an example is shown in which the system 1 is used for viewing, filling in, etc. of electronic medical records between information terminals provided at medical facilities such as hospitals, clinics, and dispensing pharmacies. However, the present embodiment is not limited to this example, and the system 1 may also be used when viewing, filling in, etc. of electronic medical records held by medical facilities, etc., using an information terminal at the user's home, in home medical care where treatment is provided at the user's home in cooperation with medical facilities, etc., home care where a helper visits the user's home according to a predetermined schedule to provide care, and home visit medical care where a doctor, etc. visits the user's home to provide medical treatment, etc.

[0056] In the system 1 according to this embodiment, the remote control device 20 is shown as an example used to view and update electronic medical records held by a remote hospital. However, this embodiment is not limited to this example, and may also be used in a case where a target computer containing highly confidential information is remotely controlled using an external computer.

[0057] [Summary of the embodiment] According to the above-described embodiment, the remote operation device 20 includes a receiving unit 21 that receives operation instructions from the viewing device 10 (external computer device) via the network NW, an operation instruction output unit 22 that outputs the received operation instructions to the operation instruction receiving unit 31 of the electronic medical record device 30 (the computer device to be operated) via the first line L1 for operation, an image signal receiving unit 23 that receives an operation signal OS output by the electronic medical record device 30 based on the operation instructions via the second line L2 for image output, and an image signal transmitting unit 24 that transmits the received operation signal OS to the viewing device 10 via the network NW. Using the first line L1, which transmits the operation signal OS but not the data folder, the user can remotely operate the electronic medical record device 30 to enter electronic medical records, but cannot send files from the viewing device 10 to the electronic medical record device 30. Therefore, the electronic medical record device 30 can prevent data files (Trojan horses, malware, etc.) required for cyberattacks from being sent. Furthermore, the second line L2, which transmits the image signal IS but not the data folder, allows the user to view the electronic medical record, but does not allow the electronic medical record device 30 to send data files to the viewing device 10. Therefore, even if a malicious user views the electronic medical record, the electronic medical record device 30 can prevent large-scale information extraction (file-by-file). Therefore, the system 1 according to the embodiment can protect confidential information while providing a mechanism for remotely controlling the electronic medical record device 30. Furthermore, the system 1 using the remote control device 20 eliminates the need for users to visit the facility where the computer containing the confidential information is located in order to directly operate the computer. Therefore, the remote control device 20 reduces the effort required for visits and contributes to alleviating labor shortages and shortening working hours. Furthermore, because the system 1 according to the embodiment does not require the construction of a highly secure network, it can be implemented relatively inexpensively while ensuring a certain level of security.

[0058] Furthermore, according to the above-described embodiment, the network NW is a virtual private network. This allows the system 1 to prevent malicious parties from remotely operating the electronic medical record device 30 using a computer device other than the viewing device 10 connected to the electronic medical record device 30. Therefore, the system 1 according to the embodiment can protect confidential information while providing a mechanism for remotely operating the electronic medical record device 30.

[0059] Furthermore, according to the above-described embodiment, the first line L1 is a universal serial bus (USB). By using a USB, which is difficult to use to send data files, as the first line L1, the system 1 can prevent data files intended for server attacks from being sent to the electronic medical record device 30. Therefore, the system 1 according to the embodiment can protect confidential information while providing a mechanism for remotely controlling the electronic medical record device 30.

[0060] Furthermore, according to the above-described embodiment, the second line L2 is a high-definition multimedia interface (HDMI). By using HDMI, which is difficult to use for transmitting data files, as the second line L2, the system 1 can prevent large-scale extraction of information stored in the electronic medical record device 30. Therefore, the system 1 according to the embodiment can protect confidential information while providing a mechanism for remotely controlling the electronic medical record device 30.

[0061] FIG. 4 is a block diagram showing an example of the internal configuration of the remote control device 20 according to this embodiment. At least some of the functions of the remote control device 20 can be implemented using a computer. As shown in the figure, the computer includes a central processing unit 901, a RAM 902, an input / output port 903, input / output devices 904 and 905, and a bus 906. The computer itself can be implemented using existing technology. The central processing unit 901 executes instructions contained in a program read from the RAM 902 or the like. In accordance with each instruction, the central processing unit 901 writes data to the RAM 902, reads data from the RAM 902, and performs arithmetic and logical operations. The RAM 902 stores data and programs. Each element included in the RAM 902 has an address and can be accessed using the address. RAM is an abbreviation for "random access memory." The input / output port 903 is a port through which the central processing unit 901 exchanges data with external input / output devices. The input / output devices 904 and 905 are input / output devices. The input / output device is, for example, a LAN controller. The input / output devices 904 and 905 exchange data with the central processing unit 901 via the input / output port 903. The bus 906 is a common communication path used within the computer. For example, the central processing unit 901 reads and writes data from and to the RAM 902 via the bus 906. Also, for example, the central processing unit 901 accesses the input / output port via the bus 906. All or part of the functional units provided in the remote operation device 20 may be realized using hardware such as an ASIC, a PLD, or an FPGA. All or part of the functional units may be realized by a combination of software and hardware.

[0062] In addition, all or part of the functions of each unit of the remote control device 20 in the above-described embodiment may be realized by recording a program for realizing these functions on a computer-readable recording medium, and reading and executing the program recorded on the recording medium into a computer system. Note that the term "computer system" here includes hardware such as an OS and peripheral devices.

[0063] Although one embodiment of the present invention has been described in detail above with reference to the drawings, the specific configuration is not limited to the above, and various design modifications can be made without departing from the spirit of the present invention. Furthermore, the configurations described in the above-described embodiments and examples can be combined. [Explanation of symbols]
