  Here, in the blood purification system according to the present embodiment, the dialysate supply device 2 (supply means) and each monitoring device 1 (blood purification means) are connected by a LAN (local area network: local communication network). It is possible to communicate bidirectional information. Thereby, in this blood purification system, predetermined information can be transmitted from the dialysate supply device 2 to the plurality of monitoring devices 1, and the predetermined information is maintained while maintaining the predetermined operation based on the above-described process signal. The plurality of monitoring devices 1 can be controlled based on the above.

  That is, the dialysate supply device 2 and each monitoring device 1 are LAN-connected via a LAN cable α, and the dialysate supply device 2 is connected to the monitoring device 1 via the LAN cable α. While the interface unit 14 and the control unit 15 for communicating between each other are disposed, the monitoring unit 1 includes an interface unit 10 for communicating with the dialysate supply device 2 via the LAN cable α and The control unit 11 (see FIG. 2) is arranged. Such a LAN is not limited to the one using the LAN cable α (wired) as in the present embodiment, but may be one that can communicate bidirectional information wirelessly (wireless LAN).

  In the dialysate supply device 2, when the interface unit 14 receives predetermined information from the monitoring device 1, a predetermined operation (preparation of dialysate, etc.) is performed by the control unit 15 based on the information, Predetermined information can be transmitted to the monitoring device 1 via the interface unit 14. In the monitoring device 1, when the interface unit 10 receives predetermined information from the dialysate supply device 2, the control unit 11 performs predetermined operations (priming before treatment, hemodialysis treatment, blood return) based on the information. Cleaning, disinfection, and the like) and predetermined information can be transmitted to the dialysate supply device 2 via the interface unit 10.

  However, the predetermined information transmitted from the dialysate supply device 2 to the plurality of monitoring devices 1 is different from the normal state (for example, dialysate that can be supplied, dialysate stock solution, lack of power, etc.) or the current time. The monitoring device 1 that has received the predetermined information, for example, can control the drive amount of the actuator included in the monitoring device 1 or adjust the clock function. It has become.

  Furthermore, the predetermined information transmitted from the dialysate supply device 2 according to the present embodiment to each monitoring device 1 includes information for controlling parameters relating to blood purification treatment (blood dialysis treatment) in the monitoring device 1. For example, the monitoring device 1 that has received the predetermined information controls the drive amount of the actuator included in the monitoring device 1 based on the predetermined information. Thus, each monitoring device 1 maintains a predetermined operation based on the process signal, and reduces the drive amount of an actuator (such as the dual pump 12 or the water removal pump 13) based on the received predetermined information, It is comprised so that the flow volume of the liquid which distribute | circulates a specific piping can be reduced selectively.

Particularly, in the present embodiment is configured capable of controlling a plurality of monitoring devices 1 uniformly in accordance with the suppliable electric power. Below, the control content of the dialysate supply apparatus 2 when there is a shortage of the dialysate which can be supplied is demonstrated as a reference example based on the flowchart of FIG. When the dialysate supply device 2 receives the remaining dialysate stock solution (residual dialysate stock amount) that can be produced by the dissolving device 3 from the dissolver device 3 in S1, the dialysate supply device 2 is based on the remaining dialysate stock solution. Then, the amount of dialysate that can be prepared by the dialysate supply device 2 (the amount of dialysate that can be prepared) is calculated (S2).

  Thereafter, when the remaining treatment time is received from each monitoring device 1 in S3, the dialysate that can be supplied to the monitoring device 1 based on the “manufacturable dialysate amount” and the “remaining treatment time”. An amount “suppliable dialysate amount” is calculated (S4), and the “suppliable dialysate amount” is transmitted to each monitoring device 1 as predetermined information (S5). In the monitoring device 1, the driving amount of the dual pump 12 is reduced in accordance with the “amount of dialysate that can be supplied”, and the amount of dialysate to be used is reduced.

In the present embodiment , for example, when the power supply that can be supplied to the blood purification system is insufficient when the power supply is switched to private power generation due to a power failure or the like in the medical facility, the driving amount of the dual pump 12 is reduced or You may make it reduce the electric power to be used by making low the temperature setting at the time of heating, such as a predetermined heater. According to such control, while maintaining a predetermined operation based on the process signal, the plurality of monitoring devices 1 can be uniformly controlled according to the circumstances regarding the power , and more appropriate responses according to various circumstances can be collectively performed. Can be done.

Next, as a reference example, the control content of the dialysate supply device 2 when the plurality of monitoring devices 1 are uniformly controlled by the operation on the dialysate supply device 2, the dissolving device 3 or the water treatment device 4 (supply means). A description will be given based on the flowchart of FIG. When the dialysate stock solution that can be prepared by the dissolution apparatus 3, the dialysate solution that can be prepared by the dialysate supply apparatus 2, or when it is switched to in-house power generation due to, for example, a power failure in a medical facility, the blood purification system When it is determined that there is a shortage in the power that can be supplied or the like, the dialysate supply device 2 is operated to reduce the flow rate of the dialysate, for example (S1). By this operation, information for reducing the flow rate of the dialysate is transmitted from the dialysate supply device 2 to each monitoring device 1 (S2). The amount of dialysate to be used and the power are reduced.

  In place of or together with the operation on the dialysate supply device 2, the operation on the dissolution device 3 or the device on the water treatment device 4 controls the plurality of monitoring devices 1 uniformly while maintaining a predetermined operation based on the process signal. It may be possible. According to such control, while maintaining a predetermined operation based on the process signal, a more appropriate response according to various circumstances can be collectively performed by operating the supply means (the dialysate supply device 2, the dissolution device 3 or the water treatment device 4). Can be done.

However, according to the blood purification system that performs the control of FIGS. 3 and 4, the control of the monitoring device 1 based on the predetermined information is performed by controlling the parameters related to the blood purification treatment (for example, by reducing the drive amount of the dual pump 12). Since the flow rate of the dialysate is reduced), it is possible to change the setting and conditions during the predetermined process in the blood purification treatment, such as reducing the flow rate of the desired liquid, and take more appropriate measures. In particular , when there is a shortage of power that can be supplied, the control of the monitoring device 1 based on the predetermined information is not limited to control of parameters related to blood purification treatment, but can be various controls for reducing the amount of power. .

Furthermore, the predetermined information transmitted to each monitoring device 1 is not limited to the information for controlling the parameters relating to blood purification treatment as described above, but is the current time information for adjusting the clock function provided in each monitoring device 1. In addition, the clock functions of the plurality of monitoring devices 1 may be collectively adjusted based on the current time information. The control content of the dialysate supply device 2 as a reference example in this case will be described based on the flowchart of FIG.

  When an operation for adjusting the “current time” is performed in the dialysate supply device 2 (S1), predetermined information including the current information is transmitted to each monitoring device 1 (S2). Accordingly, the current time in each monitoring device 1 is set, and the clock function can be adjusted collectively. According to such control, the predetermined information includes the current time information for adjusting the clock function included in each monitoring device 1, and the clock functions in the plurality of monitoring devices 1 are collectively based on the current time information. Therefore, it is possible to adjust the time more accurately and easily than that in which each monitoring device 1 individually adjusts the current time, and the workability at the time adjustment is remarkably improved. Can be improved.

  According to the embodiment, it is assumed that the predetermined information can be transmitted to the plurality of monitoring devices 1, and the plurality of monitoring devices 1 are controlled based on the predetermined information while maintaining the predetermined operation based on the process signal. Therefore, a plurality of monitoring devices 1 can be controlled according to various circumstances. In addition, it is preferable that the monitoring device 1 to which the predetermined information is transmitted is configured to further improve safety by causing the control unit 11 to individually determine the operation.

  Further, according to the present embodiment, the supply means includes the dialysate supply device 2 that can produce a dialysate having a predetermined concentration using clean water and a dialysate stock solution, and the blood purification means includes the dialysis solution. Since it consists of the monitoring apparatus 1 which supplies the dialysate supplied from the liquid supply apparatus 2 to the dialyzer 5 (blood purifier), it can be applied to a central system. In addition, since the monitoring device 1 and the dialysate supply device 2 can communicate in both directions, various information can be communicated between the monitoring device 1 and the dialysate supply device 2, which is more appropriate and safe.
