The present invention relates to a blood purification system capable of making a simpler determination or the like when an abnormality occurs in any device.

  A blood purification system usually introduces dialysate supplied from a dialysate preparation / supply device, which is a relatively large device, into a plurality of dialyzers via a pipe, and blood purification provided in each dialyzer It is constructed to provide blood purification treatment for each patient via an element (eg, a dialyzer). As the dialysis device, any form of a dialysis monitoring device capable of monitoring (monitoring) a plurality of blood purification treatments or a personal dialysis device equipped with elements necessary for blood purification treatment of a single patient can be adopted.

  In such a blood purification system, a central monitoring system capable of inputting and storing a patient's treatment schedule is provided, so that the treatment schedule can be transmitted from the central monitoring system to the dialysis monitoring device or dialysate preparation / supply device. A blood purification system has been proposed in which a dialysis monitoring device or a dialysate preparation / supply device can operate based on a treatment schedule (Patent Document 1). This Patent Document 1 also describes a configuration that enables bidirectional communication between the central monitoring system and a specific dialysate preparation / supply device or dialyzer (claim 9 of Patent Document 1). From the way of assembling each claim, it can be understood that the information to be communicated is basically limited to the treatment schedule.

JP 2012-249748 A

In the blood purification system proposed in Patent Document 1, the treatment schedule is centrally managed by the central monitoring system, and each dialysis device or dialysate preparation / supply device is based on the treatment schedule transmitted from the central monitoring system. Because it is supposed to work,
(1) Each dialysis machine in the case of dialysis machines with different treatments and processes requires judgments that are not related to or less relevant to the treatment schedule transmitted from the central monitoring system. It may be difficult for the device to perform individual operations quickly and accurately,
(2) Since a communication network in which information between each dialysis device and dialysate preparation / supply device is concentrated in the central monitoring system, the communication network as a whole blood purification system becomes complicated. If the size of the expansion increases, the communication network becomes more complicated and the maintenance and management becomes more complicated. It takes time to understand and recovery takes time.
(3) It may not be possible to detect the abnormality of each device itself in the system.
There are problems such as.

  Therefore, in view of the problems in the prior art as described above, the object of the present invention is to make each device in the system easily and appropriately operate, particularly to perform individual operations according to individual circumstances. It can be easily and inexpensively handled even when equipment is added to the system, and it can be quickly and accurately when a failure or abnormality occurs in any equipment in the system. The object is to provide a blood purification system capable of grasping the situation and recovering in a short time.

In order to solve the above problems, a blood purification system according to the present invention includes a plurality of dialyzers and at least one dialysate preparation / supply device that prepares dialysate and supplies dialysate to each dialyzer. An information communication network capable of transmitting and receiving predetermined information, which is a predetermined type of information, is established between the devices via the bidirectional communication means, and the predetermined information of all the devices in the system. A blood purification system comprising a management means for managing
The process of each device in the system can be individually set in advance, and based on the predetermined information managed by the management means, each device in the system maintains the process set individually in advance. It is configured to be individually operable.

  In the blood purification system according to the present invention as described above, the dialysate preparation / supply device means a series of device groups from preparation of dialysate to supply of dialysate to each dialyzer, for example, A purified water production apparatus, specifically, for example, a reverse osmosis purified water production apparatus (RO apparatus) and a solubilized A powder for dialysis using purified water from the purified water production apparatus A dissolving device and a dialysis B powder dissolving device for dissolving a so-called dialysis B powder, and a solution from each dissolving device are mixed at a predetermined ratio, and the mixture is predetermined using purified water from a purified water production device. It means a series of device groups composed of a multi-person dialysate supply device (so-called central device) that prepares a dialysate by adjusting the concentration of the dialysate and supplies the dialysate to each dialyzer. However, the dialysis fluid supply device for a large number of people does not have the above-mentioned dissolution apparatus, and the dialysis fluid A and the dialysis fluid B prepared in advance are mixed and adjusted to a predetermined concentration. The dialysate preparation / supply device in the present invention is a concept including such a configuration. The dialysis apparatus in the present invention is defined as a concept including both a dialysis monitoring apparatus (monitor) for multiple persons or individuals and a personal dialysis apparatus. The management means means a central monitoring server, a host computer, or the like, and is a means capable of managing predetermined information of all devices in the system.

  In the blood purification system according to the present invention as described above, an information communication network (network) capable of transmitting and receiving predetermined information between the dialysis apparatuses and the dialysate preparation / supply apparatus via the bidirectional communication means. It is constructed, and predetermined information is automatically transmitted / received between the apparatuses via the bidirectional communication means, and a management means for managing the predetermined information of all apparatuses in the system is provided. The process of each device in the system is configured to be individually settable beforehand, and based on the predetermined information managed by the management means (that is, by reading the predetermined information managed by the management means) ), Each device in the system is individually judged to maintain a process set in advance individually (that is, to maintain its own process even if the process is different from other devices) It is configured to be individually operable. Therefore, each device in the system can perform an individual operation according to an individual situation, and can easily perform an appropriate and timely individual operation. In addition, it is possible to construct a network-type information communication network via bidirectional communication means, rather than an information communication network that concentrates from all the devices in the system to the central management means. Even in such a case, it is possible to add a minimum necessary communication line network without greatly complicating the communication network, and it is possible to cope with it easily and inexpensively. In particular, a simpler and more organized information communication network can be constructed by having an intermediate management means described later. Furthermore, since the above management means manages predetermined information of all the devices in the system, if any failure or abnormality occurs in any device in the system using that information, it is managed. By using the predetermined information, it is possible to quickly and accurately grasp the situation and recover in a short time.

  In such a blood purification system according to the present invention, the management means is basically provided separately from each device in the system. For example, the management means is provided in the dialysate preparation / supply device, and is integrated into a large-sized device. It is also possible to configure. In the latter case, the information communication network can be further simplified.

  In the blood purification system according to the present invention, it is preferable that at least one intermediate management means is provided in the bidirectional communication means interposed between the device in the system and the management means. This intermediate management means is not a simple information communication repeater, but means that can manage predetermined information of devices and device groups within the range managed by the intermediate management device. By providing such an intermediate management means at an appropriate place in the system, it becomes possible to further simplify the communication network, thereby making it easier to cope with the addition of devices. In addition, it becomes possible to group the devices in the system via the intermediate management means, and it becomes possible to organize the communication network more simply by grouping, and for example, individual operations different for each group. In particular, when the scale of the blood purification system is large, the entire system can be operated more appropriately and smoothly.

  In the blood purification system according to the present invention, at least one device in the system may be provided with intermediate management means. In this way, a desirable system including intermediate management means can be realized easily and in a relatively simple form without greatly increasing the number of devices in the system.

  In addition, the predetermined information includes at least a scheduled use amount of each dialysate of the plurality of dialyzers and a dialysate preparation amount of the dialysate preparation / supply device, and the dialysate preparation / supply device includes: It is preferable that the dialysate preparation amount can be determined based on the total dialysate use amount. In such a configuration, an appropriate amount of dialysate according to the required amount can be produced. Note that the total dialysate use amount and the dialysate preparation amount are not necessarily the same, and considering the safety side, the dialysate preparation amount may be determined slightly more than the total use amount. Is possible.

  In this case, the predetermined information includes at least information related to the operation priority of the plurality of dialysis machines and a dialysis fluid preparation amount of the dialysis fluid preparation / supply device. A configuration in which a low-priority dialysis device among the plurality of dialysis devices is controlled to reduce the amount of dialysate used or to stop the use of dialysate when the amount is less than the planned use amount You can also With such a configuration, it is possible to avoid the disadvantage that the dialysate preparation amount is insufficient with respect to the total dialysate planned use amount, and the efficient operation of the dialysate in the entire system is smoothly realized.

  In the blood purification system according to the present invention, the dialysate preparation / supply device includes at least one supply means capable of supplying a cleaning solution or a disinfecting solution, and the predetermined information includes at least each device in the system. And the supply means is configured to determine the supply amount of the cleaning liquid or the disinfecting liquid based on the total expected amount of the cleaning liquid or the disinfecting liquid in the system. Adoption is possible. Here, examples of the supply means capable of supplying the cleaning liquid or the disinfecting liquid include a chemical liquid injection pump to the purified water production apparatus and a chemical liquid injection pump to the multi-person dialysis liquid supply apparatus. In such a configuration, it is possible to supply an appropriate amount of cleaning liquid or disinfecting liquid according to the required amount. Note that the scheduled use amount and the supply amount of the cleaning liquid or the disinfecting solution are not necessarily the same amount, and it is possible to determine the supply amount slightly larger than the planned use amount in consideration of the safety side.

  In this case, the predetermined information includes at least information related to the priority of cleaning or disinfection of the plurality of dialyzers and the supply amount of the cleaning liquid or the disinfecting liquid of the supply unit. A dialysis machine having a low priority of washing or disinfection among the plurality of dialysis machines reduces the amount of use of the washing liquid or the disinfecting liquid when the amount of the washing liquid or the disinfecting liquid is less than the total scheduled use amount. It can also be set as the structure controlled so that use of disinfectant may be stopped. With such a configuration, by adjusting the usage amount of the cleaning liquid or the disinfecting solution on a plurality of dialysis machines, it is possible to avoid the disadvantage that the supply amount is insufficient with respect to the total usage amount of the cleaning liquid or the disinfecting liquid. Efficient supply and operation of the cleaning liquid or disinfecting liquid is smoothly realized.

  In the blood purification system according to the present invention, each device in the system determines its own abnormality by comparing its own predetermined information with the predetermined information managed by the management means. It is possible to adopt a configuration configured to be monitorable.

  In this case, each device in the system issues an alarm and / or keeps a history if its own specific information differs from the predetermined information managed by the management means beyond a predetermined range. It is preferable that it is comprised. As described above, by providing a certain range of abnormality determination or monitoring, that is, a predetermined range of width, it is possible to avoid erroneous determination and perform more appropriate determination or monitoring.

  Thus, according to the blood purification system of the present invention, the bidirectional communication means has an information communication network (network) distributed in a flat type, and is a management means, preferably an intermediate management means. , Managing predetermined information of all devices in the system, the process of each device in the system can be individually set in advance, each device in the system based on the predetermined information managed by the management means Since each of the devices in the system can be easily and appropriately operated in a timely manner, the devices can be individually operated so as to maintain individually set processes. Further, even when a device is added in the system, it can be easily and inexpensively dealt with. Furthermore, even when a failure or abnormality occurs in any device in the system, it is possible to quickly and accurately grasp the situation and recover in a short time. And such a useful blood purification system can be constructed at a low cost as a relatively simple and organized system.
