Description

【Technical Field】 【0001】 The present disclosure relates to a blood purification system for performing blood purification treatment on a patient and a processing program executed in each component of the system. 【Background Art】 【0002】 Conventionally, as an example of a blood purification system for performing blood purification treatment on a patient, a dialysis system composed of a plurality of devices is known. The dialysis system is configured by connecting an RO device, a dissolving device, a dialysate supply device, and a dialysis device through piping. The RO device is a device that removes impurities from raw water such as tap water and purifies dialysis water (RO water). The dissolving device is a device that dissolves a dialysis agent with the RO water to prepare a dialysate stock solution. Further, the dialysate supply device is a device that dilutes the dialysate stock solution to prepare a dialysate. The dialysis device is a device that supplies the dialysate to a dialyzer attached as a consumable and performs dialysis treatment on a patient. 【0003】 Generally, each device constituting the dialysis system has an operation unit (input unit) for operating each device and a display unit (output unit) on which information related to the functions and processes of each device is displayed. For example, a touch panel type liquid crystal display is adopted as the operation unit and the display unit. In addition, medical staff (such as doctors and nurses) who manage the blood purification system will check the display information on the display unit of each device and perform operation processing on the operation unit. However, when each device is installed at a separated position, in order to perform confirmation and operation on each device, the medical staff needs to move between the devices, increasing the labor and burden of the medical staff. 【0004】 One way to reduce the effort and burden involved in such operations is to enable the entire dialysis system to operate automatically by operating just one of the devices. For example, in Patent Document 1, a dialysis system is configured so that each device operates in conjunction with the others according to a pre-set schedule, and the schedule can be set, changed, and executed by operating just one of the devices. 【0005】 Furthermore, for dialysis machines that require frequent operation and verification, there are technologies that allow various information to be displayed on a terminal device held by a medical professional, and that control be performed by operating this terminal device. For example, Patent Document 2 discloses that user input for displaying information on the screen of a dialysis machine and controlling it is performed via a mobile terminal. Patent Document 3 discloses that operation information of a dialysis machine is transmitted to a client device, and the dialysis machine is controlled by operating this client device. [Prior art documents] [Patent Documents] 【0006】 [Patent Document 1] Japanese Patent Publication No. 2012-249750 [Patent Document 2] U.S. Patent Application Publication No. 2013 / 0133036 [Patent Document 3] U.S. Patent Application Publication No. 2018 / 0036469 [Overview of the Initiative] [Problems that the invention aims to solve] 【0007】 However, if the display and control units of the designated devices for the automated operation of the entire dialysis system malfunction, or if the terminal devices that serve as replacements for the display and control units of the dialysis machine malfunction, it becomes difficult to check information and control the entire dialysis system or the dialysis machine. In particular, when such malfunctions occur, the operation of the dialysis system must be stopped and dialysis treatment must be interrupted. Furthermore, each device that makes up the dialysis system needs to display a large amount of information during maintenance, and the large size and complexity of the display units become a problem, but the conventional technology described above cannot adequately address this problem. In particular, if large and complex display units are provided for each device, the cost of the display units for each device will increase, and the manufacturing cost of the dialysis system will increase. 【0008】 This disclosure has been made in view of these challenges, and its purpose is to provide a blood purification system and a processing program for use therein that can prevent treatment interruptions in response to failures of each component while suppressing cost increases.

Common components in the drawings are denoted by the same reference numerals. 【0015】 <First Embodiment> (Configuration of the blood purification system) First, the configuration of the blood purification system of this disclosure will be described with reference to Figures 1 and 2. Here, Figure 1 is a schematic diagram showing the mechanical configuration of the blood purification system 1 according to this embodiment. In particular, Figure 1 shows the connection relationships of the fluid supply between each component constituting the blood purification system 1. Figure 2 is a schematic diagram showing the communication configuration of the blood purification system 1 according to this embodiment. In particular, Figure 2 shows the communication connection relationships between each component constituting the blood purification system 1. 【0016】 The blood purification system 1 according to this embodiment 1 is for preparing a dialysate of a predetermined concentration from a dialysate concentrate and using this dialysate to perform dialysis treatment, which is an example of blood purification treatment for patient H. In order to prepare the dialysate and perform dialysis treatment in this manner, the blood purification system 1 has a configuration in which an RO device 10, an A agent dissolving device 20, a B agent dissolving device 30, a dialysate supply device 40, and multiple dialysis machines 50, 60, which are monitoring devices for monitoring dialysis treatment, are connected by piping. Here, the multiple dialysis machines 50, 60 are installed in a dialysis room R1, which is a treatment room in a medical facility such as a hospital. On the other hand, the RO device 10, the A agent dissolving device 20, the B agent dissolving device 30, and the dialysate supply device 40 are installed in a machine room R2, which is located in a different location from the dialysis room R1. Furthermore, in the blood purification system 1 according to this embodiment 1, the RO device 10, the A agent dissolving device 20, the B agent dissolving device 30, the dialysate supply device 40, and the dialysis machines 50, 60 form a group of components that constitute the blood purification system 1. 【0017】 As shown in Figure 1, each device constituting the blood purification system 1 is connected by a group of pipes 2 consisting of multiple pipes. Specifically, the RO device 10 is connected to pipe L1 for introducing raw water and pipe L2 for discharging RO water.

In this embodiment, the communication line unit 70 consists of a hub 71 and a LAN cable 72, which is an example of a wired communication line. Therefore, each device constituting the blood purification system 1 can send and receive various types of information via wired communication through the hub 71 and the LAN cable 72. In particular, in this embodiment, when such information is sent and received, a predetermined interlocking process is performed in the blood purification system 1 in which each device operates in conjunction. Note that the communication line unit 70 only needs to be able to connect each device to each other in a manner that enables communication, and other communication devices may be provided instead of the hub 71, or a server may be added.

In other words, in this embodiment, a blood purification unit is formed with various consumables connected to the dialysis machine 50, and dialysis therapy is performed on patient H. Here, consumables include a dialyzer 80 and a blood circuit 90, which are types of blood purifiers as shown in Figure 1. 【0051】 Furthermore, the dialysis machine 50 supplies dialysate from the piping L5 to the dialyzer 80 and performs processing for dialysis treatment on patient H. In other words, the dialysis machine 50 corresponds to the blood purification unit in this disclosure. 【0052】 As can be seen from Figures 1, 2, and 7, the dialysis machine 50 has an input / output unit 51, a control unit 52, a storage unit 53, and a communication unit 54. The dialysis machine 50 also has an internal piping unit 55 for circulating dialysate between itself and the dialyzer 80, and an extracorporeal circulation unit 56 for circulating the patient H's blood outside the body. These units are electrically connected to each other via control lines and data lines. This enables the dialysis machine 50 to send and receive various signals, data, and information, as well as to perform various controls by the control unit 52. With this configuration, the dialysis machine 50 is able to take the patient H's blood outside the body (blood removal), remove unwanted or toxic substances or water from the blood in the dialyzer 80 (blood purification), and return the purified blood to the patient H (blood return). 【0053】 The input / output unit 51, like the input / output unit 11 of the RO device 10, has an input unit consisting of a touch panel type input interface and an output unit consisting of a general screen type output interface. In other words, the input / output unit 51 in this embodiment is a touch panel type liquid crystal display (display screen) equipped with an input / output interface. Furthermore, the operable area and position on the display may be freely set by the administrator of the dialysis device 50 or the like. 【0054】 Furthermore, the input interface may be separated from the input / output unit 51 in whole or in part. In this case, a keyboard with physical key buttons such as a numeric keypad or character input keys, and an input device such as a mouse may be provided in the dialysis machine 50. 【0055】 The control unit 52, like the control unit 12 of the RO device 10, is composed of a GPU or CPU and controls various parts of the dialysis machine 50 based on various programs stored in the memory unit 43. Specifically, the control unit 52 reads from the memory unit 53 and executes programs for performing processes such as displaying various information in the input / output unit 51, sending and receiving various information via the communication unit 54, circulating dialysate in the internal piping unit 55, and withdrawing and returning patient H's blood in the extracorporeal circulation unit 56, or programs for executing the OS. The control unit 52 may be composed of a single GPU or CPU, or it may be composed of a combination of multiple CPUs or GPUs. 【0056】 The memory unit 53, like the memory unit 53 of the RO device 10, is composed of ROM, RAM, non-volatile memory, HDD, etc. For example, the ROM stores instruction commands as programs for executing various processes for dialysis treatment. The RAM is used to write and read data while the program stored in the ROM is being processed by the control unit 52. The non-volatile memory is a storage device in which data is written and read as a result of the execution of the program, and the data written there is saved even after the execution of the program has finished. 【0057】 In particular, in this embodiment, the storage unit 53 stores processing programs for transmitting information about the device to other devices (RO device 10, A agent dissolving device 20, B agent dissolving device 30, dialysate supply device 40, and dialysis device 60) and for executing control of the device based on control information received from other devices. The storage unit 53 also stores processing programs for generating display information based on information provided by other devices received from other devices and outputting (displaying) it in the input / output unit 51, and for generating control information in response to the administrator's operation on the display information and transmitting the control information to the other devices that sent the provided information. 【0058】 The communication unit 54, like the communication unit 54 of the RO device 10, is composed of various electronic components and has a communication circuit. The communication unit 54 transmits and receives information between the dialysis machine 50 and other devices and other dialysis machines 50 installed at a distance from the dialysis machine 50 via a LAN cable 72 connected to the communication circuit. When transmitting and receiving information by wireless communication, the communication unit 54 may be composed of a communication processing circuit and an antenna, similar to the communication unit 54 of the RO device 10. 【0059】 The internal piping section 55 is located inside the main body of the dialysis machine 50 and is connected via piping to the dialysate inlet and dialysate outlet located on the side of the dialyzer 80. For example, the internal piping section 55 includes various components such as pipes, pumps, valves, sensors, and filters. More specifically, the internal piping section 55 may include a double pump, a water removal pump, a degassing pump, a pressure pump, a pressure reducing valve, a solenoid valve, a temperature sensor, a pressure sensor, and a chemical filter. 【0060】 The internal piping section 55 is assembled by appropriately selecting the above-mentioned components according to the piping configuration and type, and is structured to enable the circulation and cleaning of dialysate. Furthermore, the internal piping section 55 is structured to enable the introduction and discharge of dialysate to and from the dialyzer 80. Note that these specific configurations are not features of the blood purification device disclosed herein, and therefore their explanation is omitted. 【0061】 The extracorporeal circulation unit 56 is provided on the main body surface of the dialysis machine 50 and has equipment for introducing the patient's blood into the dialyzer 80 or taking it out of the dialyzer 80 via a consumable blood circuit 90. For example, the extracorporeal circulation unit 56 has a pump connected to the blood circuit 90, various sensors, etc. For example, a peristaltic pump is assumed as the pump, but other pumps such as a diaphragm pump may also be used. The configuration of the extracorporeal circulation unit 56 will vary depending on the type of dialysis machine 50, and parts may be added or removed as appropriate. 【0062】 The dialysis machine 60 is also an example of blood purification therapy, and various consumables necessary for performing dialysis treatment are connected to it. In other words, in this embodiment, a blood purification unit is formed with various consumables connected to the dialysis machine 60, and dialysis treatment is performed on patient H. Here, the consumables refer to items such as the dialyzer 80 and blood circuit 90, which are types of blood purifiers as shown in Figure 1, similar to those connected to the dialysis machine 50. 【0063】 Furthermore, the dialysis machine 60 mixes RO water supplied from piping L2, stock solution A supplied from piping L3, and stock solution B supplied from piping L4 to produce dialysate of a predetermined concentration. The dialysis machine 60 also supplies the prepared dialysate to the dialyzer 80 and processes it for dialysis treatment of patient H. In other words, the dialysis machine 60 corresponds to the blood purification unit in this disclosure, but also has the function of a dialysate supply unit in this disclosure. 【0064】 As can be seen from Figures 1, 2, and 8, the dialysis machine 60 has an input / output unit 61, a control unit 62, a storage unit 63, and a communication unit 64. The dialysis machine 60 also has an internal piping unit 65 for circulating dialysate between itself and the dialyzer 80, and an extracorporeal circulation unit 66 for circulating the patient H's body fluid, blood, outside the body. Furthermore, the dialysis machine 60 has a preparation and adjustment processing unit 67 for preparing dialysate and adjusting its concentration. Each of these units is electrically connected to the others via control lines and data lines. As a result, the dialysis machine 60 is capable of transmitting and receiving various signals, data, and information, as well as various controls by the control unit 62. 【0065】 With this configuration, the dialysis machine 60, like the dialysis machine 50, is capable of taking blood from patient H outside the body (blood removal), removing unnecessary or toxic substances or water from the blood in the dialyzer 80 (blood purification), and returning the purified blood to patient H (blood return). In addition, the dialysis machine 60 is capable of producing the dialysate necessary for dialysis treatment in-house and adjusting its concentration. 【0066】 Compared to the dialysis machine 50, the dialysis machine 60 has an additional component for preparing dialysate. Although there are differences in the details, the configuration of the dialysis machine 50 is essentially the same as the dialysis machine 50 with the addition of the dialysate preparation and adjustment processing unit 45 of the dialysate supply device 40. Therefore, a detailed explanation of each component of the dialysis machine 60 will be omitted. 【0067】 (Information transmission, reception, and display in blood purification systems) Next, the linked processing, which involves the transmission, reception, and display of information in the blood purification system 1, will be explained with reference to Figures 9 to 17. Here, Figures 9 to 11, 14, 15, and 17 are schematic diagrams showing an example of information transmission and reception in the communication configuration of the blood purification system 1 according to this embodiment. Figures 12 and 13 are examples of the display screen of the display destination device (RO device 10) of the blood purification system 1 according to this embodiment. Furthermore, Figure 16 is an example of the transition of the display screen of the display destination device (dialysis device 50) of the blood purification system 1 according to this embodiment. 【0068】 [Linked Processing 1] As an example of linked processing, the transmission and reception of information and the display of information between the Agent A dissolving device 20 and the Agent B dissolving device 30, which are connected to each other via a hub 71, will be explained with reference to Figure 9. In this linked processing, it is assumed that the Agent A dissolving device 20 is the device that displays the information related to the linked processing, and the Agent B dissolving device 30 is the device that displays the information related to the linked processing. 【0069】 First, as a prerequisite, the input / output unit 31 of the B agent dissolving device 30, which is the display target device, is operated by the administrator, and supply instruction information is generated to acquire the display information of the A agent dissolving device 20, which is the display target device. Specifically, the control unit 32 of the B agent dissolving device 30 reads and executes a predetermined program in the storage unit 33, and generates the supply instruction information based on the input information corresponding to the administrator's operation. Subsequently, the control unit 32 of the B agent dissolving device 30 controls the communication unit 34 and transmits the supply instruction information to the A agent dissolving device 20 via the LAN cable 72 and hub 71. 【0070】 Next, in Figure 9, display information is generated in the Agent A dissolving device 20, which is the display source. Specifically, when the control unit 22 of the Agent A dissolving device 20 receives the supply instruction information, the control unit 22 of the Agent A dissolving device 20 reads and executes a predetermined program in the storage unit 23 and generates display information for display in the input / output unit 21. This display information includes, for example, various information related to the dissolution process of Agent A. Next, the Agent A dissolving device 20, which is the display source, performs display processing based on the generated display information. Specifically, the control unit 22 outputs the information to the screen in the input / output unit 21 based on the display information. As a result, the administrator of the Agent A dissolving device 20 can operate the Agent A dissolving device 20 by operating the output screen. Note that this display processing may not be performed, and the Agent A dissolving device 20 may not output the information to the screen. 【0071】 Next, the display information generated in the A-agent dissolving device 20, which is the display source, is transmitted as provided information to the B-agent dissolving device 30, which is the display destination. Specifically, the control unit 22 of the A-agent dissolving device 20 controls the communication unit 24 and transmits the display information to the B-agent dissolving device 30 via the LAN cable 72 and hub 71. 【0072】 Next, the B agent dissolving device 30, which is the display destination, performs display processing based on the received display information. Specifically, the control unit 32 of the B agent dissolving device 30 reads and executes a predetermined program from the storage unit 33, and based on the received display information, outputs a screen output in the input / output unit 31 as an output similar to the display in the A agent dissolving device 20. This allows the administrator of the B agent dissolving device 30 to control the A agent dissolving device 20 by operating the output screen. In particular, the screen output may be displayed in a way that allows easy selection or switching of each device of the A agent dissolving device 20. This enables more detailed control of the A agent dissolving device 20. A dialog box may also be displayed that allows confirmation of the display source to which it is connected. Furthermore, the screen color may be different or the text color may be changed so that it is visually clear whether the display information output on the screen in the input / output unit 31 is the display information of the A agent dissolving device 20, which is the display source, or the display information of the B agent dissolving device 30, which is the display destination. 【0073】 Next, control information is generated in the B agent dissolving device 30, which is the display destination. Specifically, when the administrator of the B agent dissolving device 30 performs an input operation in the input / output unit 31, the control unit 22 of the B agent dissolving device 30 reads and executes a predetermined program in the storage unit 23 and generates control information for controlling the dissolution processing unit 25 of the A agent dissolving device 20. This control information includes, for example, various information for driving each component of the dissolution processing unit 25. Furthermore, this control information may also include on / off drive information and stop information related to the power supply of each component of the dissolution processing unit 25 or the A agent dissolving device 20 itself, i.e., on / off control information. 【0074】 Next, the control information generated in the B agent dissolving device 30, which is the display destination, is transmitted to the A agent dissolving device 20, which is the display source. Specifically, the control unit 32 of the B agent dissolving device 30 controls the communication unit 34 and transmits the control information to the A agent dissolving device 20 via the LAN cable 72 and the hub 71. 【0075】 Next, the A agent dissolving device 20, which is the source of the display, performs control processing based on the received control information. Specifically, the control unit 22 of the A agent dissolving device 20 reads and executes a predetermined program from the storage unit 23, and controls each device of the dissolution processing unit 25 based on the received control information to perform the dissolution process of A agent, stop each device, etc. 【0076】 As a result of the linked processing described above, even if the A-agent dissolving device 20 and the B-agent dissolving device 30 are installed in separate locations, it becomes possible to operate both the A-agent dissolving device 20 and the B-agent dissolving device 30 without having to move between the devices. Furthermore, even if the input / output unit 21 of the A-agent dissolving device 20 malfunctions, it becomes possible to control the A-agent dissolving device 20 and view information by operating the B-agent dissolving device 30, thereby allowing the operation of the A-agent dissolving device 20 to continue. 【0077】 In particular, the same output display becomes possible in the A agent dissolving device 20, which is the display source, and the B agent dissolving device 30, which is the display destination, improving convenience for administrators who operate both devices. Furthermore, it becomes unnecessary to install the same screen software in the B agent dissolving device 30 as in the A agent dissolving device 20, thereby reducing the development and installation costs of screen software adapted for the B agent dissolving device 30. 【0078】 Furthermore, the above-described linkage process can, of course, be performed even when the A-agent dissolving device 20 is the display destination device and the B-agent dissolving device 30 is the display source device. In addition, the above-described linkage process is not limited to processing between the A-agent dissolving device 20 and the B-agent dissolving device 30. That is, it is possible to perform the linkage process with at least one of the RO device 10, A-agent dissolving device 20, B-agent dissolving device 30, dialysate supply device 40, dialysis machine 50, and dialysis machine 60 that constitute the blood purification system 1 as the display source device, and a different device as the display destination device. In particular, the linkage process may be performed in two dialysis machines 50, or in two dialysis machines 60. 【0079】 Furthermore, priority may be set in the blood purification system 1 for the devices that will be displayed and the devices that will be displayed. For example, devices located downstream in the blood purification system 1 may be given a higher priority to be displayed, while devices located upstream may be given a lower priority to be displayed. Similarly, devices located downstream in the blood purification system 1 may be given a lower priority to be displayed, while devices located upstream may be given a higher priority to be displayed. More specifically, the RO device 10 may be given a priority to be displayed rather than to be displayed, and the dialysate supply device 40, dialysis machines 50, 60 may be given a priority to be displayed rather than to be displayed. This priority may be treated as common information in the blood purification system 1, and each device may be able to set this priority as appropriate. 【0080】 Furthermore, while display information for display on the destination device was transmitted from the display source to the destination device as provided information, the base information constituting the display information may also be transmitted as provided information. In other words, instead of the display source device generating the display information to be displayed on the destination device, the display information may be generated at the destination device based on the base information. This makes it possible for the destination device to output a display suitable for its own display screen, even if there are differences in dimensions, layout, etc., between the display screen at the destination and the display screen at the display source. In addition, in such a case, it becomes possible to omit some of the display hardware and software on the display source device, leading to cost reduction. 【0081】 In addition, in the above-described interlocking process, the control unit of the display source executes control based on the control information generated during the operation of the display destination. However, the control unit of the display destination may directly control each device of the display source. That is, the display destination device may generate control information (control signals) to drive each part and each device that constitutes the display source device, and supply this control information directly to each part via the communication unit without going through the control unit of the display source. 【0082】 Furthermore, the above variations are basically the same for other linked processes described below. 【0083】 [Linked Processing 2] As another example of linked processing, the transmission and reception of information and the display of information between the RO device 10 and the dialysate supply device 40, which are connected communicably via the hub 71, will be explained with reference to Figure 10. In this linked processing, as an example, it is assumed that the RO device 10, which has a relatively small input / output unit 11, is the device that displays the information related to the linked processing, and the dialysate supply device 40, which has a relatively large input / output unit 41, is the device to which the information related to the linked processing is displayed. 【0084】 First, as a prerequisite, the input / output unit 41 of the dialysis fluid supply device 40, which is the display target device, is operated by the administrator, and supply instruction information is generated to acquire various information from the RO device 10, which is the display target device. Specifically, the control unit 42 of the dialysis fluid supply device 40 reads and executes a predetermined program in the storage unit 43, and generates the supply instruction information based on the input information corresponding to the administrator's operation. Subsequently, the control unit 42 of the dialysis fluid supply device 40 controls the communication unit 44 and transmits the supply instruction information to the RO device 10 via the LAN cable 72 and hub 71. 【0085】 Next, in Figure 10, the RO device 10, which is the display source, generates the information to be provided. Specifically, when the control unit 12 of the RO device 10 receives the supply instruction information, the control unit 12 of the RO device 10 reads and executes a predetermined program in the storage unit 13 to generate information to be provided, which includes various information related to the production of RO water. In particular, the information to be provided may include information that is not displayed in the RO device 10. Next, the information to be provided generated in the RO device 10, which is the display source, is transmitted as information to the dialysis fluid supply device 40, which is the display destination. Specifically, the control unit 12 of the RO device 10 controls the communication unit 14 and transmits the information to the dialysis fluid supply device 40 via the LAN cable 72 and the hub 71. 【0086】 Next, in the dialysate supply device 40, which is the display destination, display information to be output on the dialysate supply device 40 is generated based on the received information. Specifically, the control unit 42 of the dialysate supply device 40 reads and executes a predetermined program in the storage unit 43, and uses various information contained in the provided information to generate display information for output display in the input / output unit 41. Here, this display information may include information that is not output display in the input / output unit 11 of the RO device 10. After that, the control unit 42 of the dialysate supply device 40 outputs the information on the screen in the input / output unit 41 based on the generated display information. As a result, the administrator of the dialysate supply device 40 can control the RO device 10 by operating the output screen. 【0087】 Next, control information is generated in the dialysate supply device 40, which is the display destination. Specifically, when the administrator of the dialysate supply device 40 performs an input operation in the input / output unit 41, the control unit 42 of the dialysate supply device 40 reads and executes a predetermined program in the storage unit 43 and generates control information for controlling the purification unit 15 of the RO device 10. This control information includes, for example, various information for driving or stopping each device of the purification unit 15. 【0088】 Next, the control information generated in the dialysis fluid supply device 40, which is the display destination, is transmitted to the RO device 10, which is the display source. Specifically, the control unit 42 of the dialysis fluid supply device 40 controls the communication unit 44 and transmits the control information to the RO device 10 via the LAN cable 72 and hub 71. 【0089】 Next, the RO device 10, which is the source of the display, performs control processing based on the received control information. Specifically, the control unit 12 of the RO device 10 reads and executes a predetermined program from the storage unit 13, and controls each piece of equipment in the purification unit 15 based on the received control information, performing RO water production processing and stopping each piece of equipment. 【0090】 As a result of the linked processing described above, the following effects are achieved in addition to the effects of linked processing 1. In this linked processing, the dialysis fluid supply device 40, which has an input / output unit 41 that is larger in dimensions than the input / output unit 11 of the display source, becomes the display destination. Therefore, more detailed information that cannot be displayed due to the dimensional limitations of the input / output unit 11 can be displayed as an output screen on the input / output unit 41 of the dialysis fluid supply device 40. This makes it possible to perform more detailed control and view information on the display source device using the display destination device. 【0091】 Furthermore, in this linked processing, if the dimensions of the input / output unit of the display source are smaller than the dimensions of the input / output unit of the display destination, the system may select which device will be the display source and which will be the display destination. 【0092】 [Linked Processing 3] As another example of linked processing, the transmission and display of information between the RO device 10, dialysis device 50, and dialysis device 60, which are connected to each other via the hub 71, will be explained with reference to Figures 11 to 13. In this linked processing, as an example, it is assumed that the dialysis device 50 and dialysis device 60 are the devices that display the information related to the linked processing, and the RO device 10 is the device to which the information related to the linked processing is displayed. 【0093】 First, as a prerequisite, the input / output unit 11 of the RO device 10, which is the display target device, is operated by the administrator, and supply instruction information is generated to acquire display information from the dialysis machines 50 and 60, which are the display target devices. Specifically, the control unit 12 of the RO device 10 reads and executes a predetermined program from the storage unit 13, and generates the supply instruction information based on the input information corresponding to the administrator's operation. Subsequently, the control unit 12 of the RO device 10 controls the communication unit 14 and transmits the supply instruction information to the dialysis machines 50 and 60 via the LAN cable 72 and hub 71. 【0094】 Next, in Figure 11, display information is generated in the dialysis machines 50 and 60, which are the display sources. Specifically, when the control unit 52 of dialysis machine 50 receives the supply instruction information, the control unit 52 reads and executes a predetermined program in the storage unit 53 to generate display information for display in the input / output unit 51. Similarly, when the control unit 62 of dialysis machine 60 receives the supply instruction information, the control unit 62 reads and executes a predetermined program in the storage unit 63 to generate display information for display in the input / output unit 61. This display information includes, for example, information on the progress of dialysis treatment in each dialysis machine and the patient's condition (pulse, blood pressure, etc.). 【0095】 Next, the dialysis machines 50 and 60, which are the source of the display, perform display processing based on the generated display information. Specifically, the control unit 52 of the dialysis machine 50 outputs to the screen at the input / output unit 51 based on the display information, and the control unit 62 of the dialysis machine 60 outputs to the screen at the input / output unit 61 based on the display information. As a result, the administrators of the dialysis machines 50 and 60 can operate the dialysis machines 50 and 60 by operating the outputted screen. Note that this display processing may not be performed, and the dialysis machines 50 and 60 may not output to the screen based on the display information. 【0096】 Next, the display information generated in the dialysis machine 50 and dialysis machine 60, which are the display sources, is transmitted as provided information to the RO machine 10, which is the display destination. Specifically, the control unit 52 of the dialysis machine 50 controls the communication unit 54 and transmits its own display information to the RO machine 10 via the LAN cable 72 and hub 71, while the control unit 62 of the dialysis machine 60 controls the communication unit 64 and transmits its own display information to the RO machine 10 via the LAN cable 72 and hub 71. 【0097】 Next, the RO device 10, which is the display destination, performs display processing based on each of the received display information. Specifically, the control unit 12 of the RO device 10 reads and executes a predetermined program from the storage unit 13, and outputs to the screen at the input / output unit 11 based on each of the received display information and the display information generated in its own device. For example, as shown in Figure 12, the input / output unit 11 is set up with two display units, the first display unit 11a and the second display unit 11b. The control unit 12 of the RO device 10 may output and display the display information of the display destination device, which is its own device, on the first display unit 11a, and selectively output and display the display information of the dialysis machine 50 and the dialysis machine 60 on the second display unit 11b. Of course, the control unit 12 may appropriately select the display information from the receiving display source and the display information of its own device, and output and display them on the first display unit 11a and the second display unit 11b, and switch between them as needed. 【0098】 Next, control information is generated in the RO device 10, which is the display destination. Specifically, when the administrator of the RO device 10 performs an input operation in the input / output unit 11, the control unit 12 of the RO device 10 reads and executes a predetermined program in the storage unit 13 and generates control information for controlling each part of the dialysis machine 50 and the dialysis machine 60. This control information includes, for example, various information for driving or stopping the internal piping unit 55 and the extracorporeal circulation unit 56 of the dialysis machine 50, and the internal piping unit 65, the extracorporeal circulation unit 66, and the manufacturing adjustment processing unit 67 of the dialysis machine 60. 【0099】 Next, the control information generated in the RO device 10, which is the display destination, is transmitted to the dialysis machines 50 and 60, which are the display sources. Specifically, the control unit 12 of the RO device 10 controls the communication unit 14 and transmits the control information to the dialysis machines 50 and 60 via the LAN cable 72 and the hub 71. 【0100】 Next, control processing is performed in the dialysis machines 50 and 60, which are the source of the display, based on the received control information. Specifically, the control unit 52 of the dialysis machine 50 reads and executes a predetermined program from the storage unit 53, controls each piece of equipment in each section based on the received control information, and starts or stops dialysis treatment. Similarly, the control unit 62 of the dialysis machine 60 reads and executes a predetermined program from the storage unit 63, controls each piece of equipment in each section based on the received control information, and starts or stops dialysis treatment. 【0101】 As a result of the linked processing described above, the following effects are achieved in addition to the effects of linked processing 1. In this linked processing, the display information of the display source and the display information of the display destination are output and displayed on the same screen, allowing the administrator of the display destination to efficiently grasp various information of both the display destination and the display source. In particular, various information of both the display destination and the display source is updated in real time, allowing each device to be controlled based on the latest information. 【0102】 In this linked processing, the scenario assumed two source devices, but three or more may also be used. In such cases, as shown in Figure 13, the number of display units at the destination may be increased according to the number of source devices. In this case, the display information of multiple dialysis machines will be displayed on the input / output unit 11 of the RO unit 10, allowing the administrator of the RO unit 10 to simultaneously check the status of multiple dialysis machines and patients H. 【0103】 Alternatively, the dimensions of the first display unit 11a or the second display unit 11b in Figure 12 may be reduced for output display, and the administrator can select the reduced output display to enlarge it. This allows necessary output displays to be enlarged and unnecessary displays to be reduced, enabling the administrator to accurately grasp the necessary information. 【0104】 Furthermore, in the state shown in Figure 12, if the administrator performs an input operation, a confirmation screen may be displayed to verify whether the input operation is normal. This prevents erroneous inputs that unintentionally control other devices, even when display information from different devices is shown on the same screen, and enables more accurate control of the devices in the blood purification system 1. 【0105】 Furthermore, in the state shown in Figure 12, it may be possible to visually identify which device the display information shown in the first display unit 11a or the second display unit 11b belongs to. For example, misrecognition may be prevented by using different colors for the characters displayed in the output, changing the font of the characters, or surrounding each piece of display information with a frame of a different color. 【0106】 [Linked Processing 4] As another example of linked processing, the transmission and display of information between the B agent dissolving device 30 and the dialysate supply device 40, which are connected to each other via a hub 71, will be explained with reference to Figure 14. In this linked processing, as an example, it is assumed that the B agent dissolving device 30 is the device that displays the information related to the linked processing, and the dialysate supply device 40 is the device to which the information related to the linked processing is displayed. 【0107】 First, as a prerequisite, the input / output unit 41 of the dialysate supply device 40, which is the display target device, is operated by the administrator, and supply instruction information is generated to acquire the display information of the B agent dissolving device 30, which is the display target device. Specifically, the control unit 42 of the dialysate supply device 40 reads and executes a predetermined program in the storage unit 43, and generates the supply instruction information based on the input information corresponding to the administrator's operation. Subsequently, the control unit 42 of the dialysate supply device 40 controls the communication unit 44 and transmits the supply instruction information to the B agent dissolving device 30 via the LAN cable 72 and hub 71. 【0108】 Next, in Figure 14, display information is generated in the B agent dissolving device 30, which is the display source. Specifically, when the control unit 32 of the B agent dissolving device 30 receives the supply instruction information, the control unit 32 reads and executes a predetermined program in the storage unit 33 and generates display information for display in the input / output unit 31. This display information includes, for example, various information related to the dissolution process of agent B. At this point, the B agent dissolving device 30, which is the display source, does not perform any display processing based on the generated display information, the input / output unit 31 blacks out, and input operations become impossible. 【0109】 Next, the display information generated in the B agent dissolving device 30, which is the display source, is transmitted as provided information to the dialysis fluid supply device 40, which is the display destination. Specifically, the control unit 32 of the B agent dissolving device 30 controls the communication unit 34 and transmits the display information to the dialysis fluid supply device 40 via the LAN cable 72 and hub 71. 【0110】 Next, the dialysate supply device 40, which is the display destination, performs display processing based on the received display information. Specifically, the control unit 42 of the dialysate supply device 40 reads and executes a predetermined program from the storage unit 43, and based on the received display information, outputs a screen output in the input / output unit 41 as an output similar to the display on the B agent dissolving device 30. As a result, the administrator of the dialysate supply device 40 can control the B agent dissolving device 30 by operating the output screen. 【0111】 Next, control information is generated in the dialysate supply device 40, which is the display destination. Specifically, when the administrator of the dialysate supply device 40 performs an input operation in the input / output unit 41, the control unit 42 of the dialysate supply device 40 reads and executes a predetermined program in the storage unit 43 and generates control information for controlling the dissolution processing unit 35 of the B agent dissolution device 30. This control information includes, for example, various information for driving or stopping each component of the dissolution processing unit 35. 【0112】 Next, the control information generated in the dialysate supply device 40, which is the display destination, is transmitted to the B agent dissolving device 30, which is the display source. Specifically, the control unit 42 of the dialysate supply device 40 controls the communication unit 44 and transmits the control information to the B agent dissolving device 30 via the LAN cable 72 and hub 71. 【0113】 Next, the B agent dissolving device 30, which is the source of the display, performs control processing based on the received control information. Specifically, the control unit 32 of the B agent dissolving device 30 reads and executes a predetermined program from the storage unit 33, and controls each device of the dissolution processing unit 35 based on the received control information to perform the dissolution process of B agent, stop each device, etc. 【0114】 As a result of the linked processing described above, the following effects are achieved in addition to the effects of linked processing 1. In this linked processing, since no screen display is made on the display source, operation on the display source becomes impossible. Therefore, separate operations on both the display source and the display destination are prevented, and unintended processing is not executed on the display source. 【0115】 [Linked Processing 5] As another example of linked processing, the transmission and reception of information and the display of information between devices connected to each other via the hub 71 will be explained with reference to Figures 15 and 16. In this linked processing, it is assumed that the RO device 10, the A agent dissolving device 20, the B agent dissolving device 30, the dialysate supply device 40, and the dialysis machine 60 are the devices that display the information related to the linked processing, and the dialysis machine 50 is the device to which the information related to the linked processing is displayed. Note that the generation and transmission and reception of supply instruction information, display information, and control information are the same as those in linked processing 1 to 4 above, so their explanation will be omitted, and only the differences will be explained. 【0116】 As shown in Figure 15, the dialysis machine 50 receives display information from other devices, and the dialysis machine 50 receives control information from other devices. Although not shown in the figure, the dialysis machine 50 also receives supply instruction information from other devices to initiate the generation of this control information. 【0117】 As shown in Figure 16, the input / output unit 51 of the dialysis machine 50 can display information for the RO unit 10, A agent dissolving unit 20, B agent dissolving unit 30, dialysate supply unit 40, and dialysis machine 60 in a sequential manner. More specifically, the administrator can slide (swipe) the input / output unit 51 vertically to display other devices other than the dialysis machine in sequence. On the other hand, the administrator can slide (swipe) the input / output unit 51 horizontally to display multiple dialysis machines, including their own, in sequence on the input / output unit 51. 【0118】 As a result of the linked processing described above, the following effects are achieved in addition to the effects of linked processing 1. In this linked processing, the display information of the display source and the display information of the display destination are displayed on the same screen, allowing the administrator of the display destination to efficiently grasp various information of both the display destination and the display source. 【0119】 [Linked Processing 6] As another example of linked processing, the transmission and display of information between the RO device 10 and the dialysate supply device 40, which are connected to each other via a hub 71, will be explained with reference to Figure 17. In this linked processing, one example is assumed in which the dialysate supply device 40 is the device that displays the information related to the linked processing, and the RO device 10 is the device that displays the information related to the linked processing. 【0120】 First, as a prerequisite, the input / output unit 11 of the RO device 10, which is the display target device, is operated by the administrator, and supply instruction information is generated to acquire various information from the dialysis fluid supply device 40, which is the display target device. Specifically, the control unit 12 of the RO device 10 reads and executes a predetermined program in the storage unit 13, and generates the supply instruction information based on the input information corresponding to the administrator's operation. Subsequently, the control unit 12 of the RO device 10 controls the communication unit 14 and transmits the supply instruction information to the dialysis fluid supply device 40 via the LAN cable 72 and hub 71. 【0121】 Next, in Figure 17, the dialysate supply device 40, which is the source of the display, generates display information as provided information. Specifically, when the control unit 42 of the dialysate supply device 40 receives the supply instruction information, the control unit 42 of the dialysate supply device 40 reads and executes a predetermined program in the storage unit 43, and generates display information that includes various information related to the preparation of dialysate. Furthermore, if any abnormality is detected in the dialysate supply device 40, the control unit 42 generates notification information corresponding to the abnormality and issues a predetermined alarm from the input / output unit 41. 【0122】 Next, when display information or notification information is generated in the dialysis fluid supply device 40, which is the display source, this information is transmitted as provided information to the dialysis fluid supply device 40, which is the display destination. Specifically, the control unit 42 of the dialysis fluid supply device 40 controls the communication unit 44 and transmits the provided information to the RO device 10 via the LAN cable 72 and hub 71. Subsequently, the RO device 10, which is the display destination, outputs a display or notification based on the received provided information. Specifically, when the control unit 12 receives display information, the input / output unit 11 outputs a screen based on the display information. Also, when the control unit 12 receives notification information, the input / output unit 11 issues a predetermined alarm based on the notification information. As a result, the administrator of the RO device 10 can understand the abnormality of the dialysis fluid supply device 40 and take action to address the abnormality by operating the output screen. 【0123】 Next, control information is generated in the RO device 10, which is the display destination. Specifically, when the administrator of the RO device 10 performs an input operation in the input / output unit 11, the control unit 12 of the RO device 10 reads and executes a predetermined program in the storage unit 13 and generates control information for controlling the preparation and adjustment processing unit 45 of the dialysate supply device 40. This control information includes, for example, various information for driving or stopping each component of the preparation and adjustment processing unit 45. 【0124】 Next, the control information generated in the RO device 10, which is the display destination, is transmitted to the dialysate supply device 40, which is the display source. Specifically, the control unit 12 of the RO device 10 controls the communication unit 14 and transmits the control information to the dialysate supply device 40 via the LAN cable 72 and hub 71. 【0125】 Next, the dialysate supply device 40, which is the source of the display, performs control processing based on the received control information. Specifically, the control unit 42 of the dialysate supply device 40 reads and executes a predetermined program from the storage unit 43, and controls each device of the preparation and adjustment processing unit 45 based on the received control information, and performs actions such as stopping each device involved in the preparation and adjustment of dialysate. 【0126】 As a result of the linked processing described above, the following effects are achieved in addition to the effects of linked processing 1. In this linked processing, the destination device also issues an alarm regarding the device malfunction, just as the source device. This makes it easy for the administrator to identify malfunctions in other devices located in different locations, and enables them to respond to such malfunctions more quickly. 【0127】 Furthermore, the alarms that notify of the above-mentioned abnormalities may be designed to distinguish between abnormalities in the device that displays the information (the device itself) and abnormalities in the device that displays the information (another device). For example, different alarm sounds or different indicator lights may be used to notify the system. 【0128】 (Effects of the first embodiment) In this embodiment, since each device constituting the blood purification system 1 is connected to enable information communication with one another, it is possible to display information from at least one device (display source) constituting the blood purification system 1 on other devices (display destinations). This makes it possible to control the display source device, which is located at a distance from the display source device, by operating the display destination device. Such control eliminates the need to enlarge the display units of each device in the blood purification system 1 or to incorporate complex structures, thereby suppressing cost increases for the blood purification system 1. Furthermore, such control prevents interruptions to dialysis treatment in response to failures in each device. 【0129】 (Modification of the first embodiment) In the embodiment described above, the blood purification system 1 had an RO device 10, an A agent dissolving device 20, a B agent dissolving device 30, a dialysate supply device 40, a dialysis machine 50, a dialysis machine 60, and a communication line unit 70, but it is not necessary to have all of these. For example, the blood purification system 1 may consist of an RO device 10, an A agent dissolving device 20, a B agent dissolving device 30, a dialysate supply device 40, a dialysis machine 50, and a communication line unit 70, or it may consist of an RO device 10, an A agent dissolving device 20, a B agent dissolving device 30, a dialysis machine 60, and a communication line unit 70. In other words, the blood purification system 1 may be of various types as long as the devices necessary for performing dialysis treatment on patient H are connected by the communication line unit 70. In particular, the blood purification system of this disclosure does not need to have separate devices for the blood purification unit, dialysate supply unit, dissolving unit, dialysis water purification unit, and communication line unit, and may be a system in which multiple such units are included in one device. 【0130】 Furthermore, the display information of the components constituting the blood purification system 1 may be displayed on a mobile terminal or other arbitrary device held by the administrator, allowing control of each component. Wireless LAN or Bluetooth® may be used as the means of communication in this case. 【0131】 <Second Embodiment> In the first embodiment, each device constituting the blood purification system 1 was provided with an input / output unit, but it is possible to omit the input / output units from some of the devices. That is, the device that serves as the display source may not include a display screen for outputting display information. This configuration will be described as the second embodiment with reference to Figure 18. Here, Figure 18 is a schematic diagram showing the mechanical configuration and communication configuration of the blood purification system according to this embodiment. Note that the parts that differ from the first embodiment will be described in principle, and the same content will be omitted from the description, and the same reference numerals will be used in the drawings in principle. 【0132】 In this embodiment, as shown in Figure 18, the blood purification system 101 includes an RO device 110, a drug A dissolving device 120, a drug B dissolving device 130, a dialysate supply device 40, a dialyzer 50, and a dialyzer 60. In the blood purification system 101, each device is connected to the others via a hub 71 that constitutes the communication line section and a LAN cable (not shown). 【0133】 In the linked processing of this embodiment, it is assumed that the RO device 110, the A agent dissolving device 120, and the B agent dissolving device 130 are the devices that display information related to the linked processing, and the dialysate supply device 40 is the device to which the information related to the linked processing is displayed. As can be seen from Figure 18, the RO device 110, the A agent dissolving device 120, and the B agent dissolving device 130, which are the display source devices, are not provided with input / output units. Therefore, information related to the RO device 110, the A agent dissolving device 120, and the B agent dissolving device 130 will be output and displayed on the input / output unit 41 of the dialysate supply device 40, which is the display destination device. Furthermore, the control of the RO device 110, the A agent dissolving device 120, and the B agent dissolving device 130 will be performed via the input / output unit 41 of the dialysate supply device 40, which is the display destination device. 【0134】 For devices without input / output units, appropriate selections can be made depending on the frequency of use, maintenance, and status checks of the device. While it is preferable to select a device with a relatively large input / display unit for the display destination, this is not particularly limited, and appropriate selections may be made depending on the dialysis treatment situation. 【0135】 (Effects of the second embodiment) As described above, this embodiment will have the same effects as the first embodiment, but it will also have the following effects. In this embodiment, devices that do not require information display do not have input / output units, thus reducing the cost of each device. 【0136】 <Third Embodiment> The status of the linked processing in the blood purification system may be made visible to the administrator. That is, a display mechanism may be provided that can indicate that the device is performing linked processing. This configuration will be described as a second embodiment with reference to Figure 19. Here, Figure 19 is a schematic diagram showing the mechanical configuration and communication configuration of the blood purification system according to this embodiment. Note that the parts that differ from the first embodiment will be described in principle, and the same content will be omitted from the explanation, and the same reference numerals will be used in the drawings in principle. 【0137】 As shown in Figure 19, each device constituting the blood purification system 201 is equipped with an interlocking indicator light. Specifically, the RO device 210 is equipped with an interlocking indicator light 218 on the side of the input / output unit 11. The A agent dissolving device 220 is equipped with an interlocking indicator light 228 on the side of the input / output unit 21, and the B agent dissolving device 230 is equipped with an interlocking indicator light 238 on the side of the input / output unit 31. The dialysate supply device 240 is equipped with an interlocking indicator light 248 above the input / output unit 41. In addition, the dialysis machine 250 is equipped with an interlocking indicator light 258 inside the input / output unit 51, and the dialysis machine 260 is equipped with an interlocking indicator light 268 inside the input / output unit 61. 【0138】 In the interlocking process of this embodiment, as an example, it is assumed that the B agent dissolving device 230 becomes the device that displays the information related to the interlocking process, and the RO device 210 becomes the device that displays the information related to the interlocking process. As shown in Figure 19, the interlocking indicator light 218 of the RO device 210 and the interlocking indicator light 238 of the B agent dissolving device 230 are illuminated in conjunction with each other. The timing of the start of illumination of the interlocking indicator lights in each device may be when the supply instruction information is sent and received in the interlocking process described above, or when the display information, which is an example of the information to be provided, is sent and received. For this reason, the control unit of each device may perform a drive process to illuminate the interlocking indicator light when receiving or sending this information. Naturally, if the selection of the device that will be the display source is changed by the administrator, the illuminated interlocking indicator light will turn off, and the interlocking indicator light of the device in which the interlocking process will be newly started will light up. 【0139】 Furthermore, if there are multiple groups of devices performing linked processing, the color of the linked indicator light may be changed for each group of linked devices. In addition, each linked indicator light may be made to visually indicate the linked status not only by being lit but also by flashing. Furthermore, for devices whose linked indicator light is lit, the color of the output display in the input / output section may be different from the color of the output display in the input / output section of other devices that are not performing linked processing. 【0140】 (Effects of the third embodiment) As described above, this embodiment will have the same effects as the first embodiment, but it will also have the following effects. In this embodiment, the devices that are performing the linked processing can be easily identified, and it is possible to prevent accidental operation of the display source device. 【0141】 <Embodiments of this disclosure> A first embodiment of the present disclosure is a blood purification system comprising: a plurality of blood purification units for purifying a patient's blood; a dialysate supply unit for supplying dialysate to the blood purification units; a dissolving unit for supplying dialysate concentrate to the dialysate supply unit; a dialysate purification unit for purifying dialysate and supplying it to at least one of the dialysate supply unit and the dissolving unit; and a communication line unit for communicating with at least two of the plurality of blood purification units, the dialysate supply unit, the dissolving unit, and the dialysate purification unit, wherein at least one of the components including the plurality of blood purification units, the dialysate supply unit, the dissolving unit, and the dialysate purification unit is designated as the display source, a component from the component group different from the display source is designated as the display destination, display information is output at the display destination based on provided information transmitted from the display source to the display destination, control information generated by operations on the display information is transmitted from the display destination to the display source, and control of the display source is executed to perform linked processing between the display source and the display destination. 【0142】 Because the components of the blood purification system are connected in a way that allows them to communicate with each other, it is possible to display information from at least one display source of the blood purification system on a display destination. This makes it possible to control a display source located at a distance from the original display source by operating the display destination. By performing this type of control, it becomes unnecessary to enlarge the screens or incorporate complex structures in the display units of each component of the blood purification system, thereby suppressing the increase in the cost of the blood purification system. Furthermore, by performing this type of control, it is possible to prevent interruptions in dialysis treatment in response to failures in each component. 【0143】 A second embodiment of this disclosure is that, in the first embodiment, the plurality of blood purification units, the dialysate supply unit, the dissolution unit, and the dialysate water purification unit can be either the display source or the display destination. This allows for response to failures in any of the components and enables more accurate prevention of interruptions in dialysis treatment. 【0144】 A third embodiment of this disclosure is that, in the first or second embodiment, the destination display screen has larger dimensions than the source display screen. This allows the destination screen to display various types of information that cannot be displayed on the source screen, and enables more detailed control over the source screen. 【0145】 A fourth embodiment of this disclosure is that, in any of the first to third embodiments, the display source does not include a display screen for outputting the display information. This reduces the cost of providing a display screen and other related costs, and also leads to a reduction in the cost of the blood vessel purification system itself. 【0146】 A fifth embodiment of this disclosure is that, in any of the first to fourth embodiments, the display screen of the destination displays the display information of the destination and the display information of the source. This allows for real-time and simultaneous confirmation of the information of the destination and source, making it easier to control the destination and source and to confirm the information. 【0147】 A sixth embodiment of this disclosure is that, in any of the first to fifth embodiments, the provided information includes alarm information, and the same alarm is output from the display source and the display destination. This makes it possible to easily and quickly identify failures in each component and to respond to the failures without interrupting treatment. 【0148】 A seventh embodiment of this disclosure is, in the second embodiment, the plurality of blood purification units, the dialysate supply unit, the dissolution unit, and the dialysate water purification unit are equipped with interlocking indicator lights, and the indicator source and the indicator destination illuminate the interlocking indicator lights when the interlocking process is performed. This makes it easy to visually identify the components performing the interlocking process and prevents erroneous operation. 【0149】 An eighth embodiment of this disclosure is, in the second embodiment, that input operations on the display source become impossible during the linked processing. This prevents erroneous operations on the display source and eliminates inconsistencies in control instructions between the configurations performing the linked processing. 【0150】 A ninth embodiment of this disclosure is, in the second embodiment, that the control information includes power on / off control information for the display source. This makes it possible to stop the drive of the display source by operating the display destination, even if the drive of the display source cannot be stopped by operating the display source. 【0151】 A tenth embodiment of the present disclosure is a processing program executed in each configuration of a blood purification system, where the display source is at least one of a group of components including a plurality of blood purification units for purifying a patient's blood, a dialysate supply unit for supplying dialysate to the blood purification units, a dissolving unit for supplying dialysate concentrate to the dialysate supply unit, and a dialysate purification unit for purifying dialysate and supplying it to at least one of the dialysate supply unit and the dissolving unit, and the display destination is a configuration from the group of components different from the display source, the processing program transmits information from the display source to the display destination, outputs display information at the display destination based on the information transmitted, generates control information by operating on the display information, transmits the control information from the display destination to the display source, and executes control of the display source based on the control information. 【0152】 This processing program makes it possible to display information from at least one display source constituting the blood purification system on a display destination. This makes it possible to control a display source located at a distance from the original display source by operating the display destination. By performing this type of control, it becomes unnecessary to enlarge the screens or incorporate complex structures in the display units of each component of the blood purification system, thereby suppressing the increase in the cost of the blood purification system. Furthermore, by performing this type of control, it is possible to prevent interruptions in dialysis treatment in response to failures in each component. [Explanation of symbols] 【0153】 1.
