I am trying to manufacture. Then, the dialysate produced by the dialysate supply device is distributed and supplied to a plurality of dialyzers connected in parallel to the dialysate supply device, and the patient monitoring device provided for each dialyzer supplies the dialysate liquid to each dialyser. The supply status of the supplied dialysate is monitored.

が終了するまで洗浄を待つ必要があった。[Problems to be solved by the device] By the way, the dialysis time of patients undergoing dialysis is usually different depending on their medical condition and physical condition, and the dialysis is performed simultaneously by a plurality of dialyzers connected to the dialysate supply device. Even if you start, each end time will be different. When the dialysis is completed, it is necessary to remove the dialyzer and wash the patient monitoring device, but as described above, the conventional dialysis device should wash the dialysate supply device and each patient monitoring device at the same time. As a result, it is not possible to clean only some of the patient monitors, and therefore it has been necessary to wait for the cleaning until all patients have been dialyzed.

ある。“Means for Solving the Problems” In view of such circumstances, the present invention is a dialysis apparatus described above, that is, a concentrated liquid is supplied from a concentrated liquid supply source, and water is supplied from a water supply source to produce a mixed dialysate solution. Further, a dialysate supply device for supplying a cleaning liquid from a cleaning liquid supply source for cleaning, a plurality of dialyzers connected in parallel to the dialysate supply device, and a dialysate supplied from the dialysate supply device to each dialyzer. In a dialysis machine comprising a plurality of patient monitoring devices for respectively monitoring the supply state of dialysate, each of the patient monitoring devices is separately provided with a cleaning liquid supply source for supplying a cleaning liquid without going through the dialysate supply device. It is designed to be connected to a water supply source that supplies water.

させることができる。[Operation] According to the above configuration, when dialysis by some of the patient monitoring devices is completed, only the patient monitoring device concerned is supplied with the cleaning liquid and the water supply source from the cleaning liquid supply source without passing through the dialysate supply device. Since it is possible to supply water from the patient monitoring device, it is possible to wash only the patient monitoring device for which dialysis has been completed while continuing the dialysis work by the dialysate supply device and the other patient monitoring device. The operating rate of the device can be improved.

する。Then, for example, when dialysis in the dialyzer 15a is completed,
The electromagnetic on-off valve 17a is closed to stop the supply of dialysate, the dialyzer 15a is separated from the patient, and the used dialyzer 15a is removed. After that, while continuing the dialysis in the other dialyzer 15b, 15c, the cleaning pumps 35, 37 are activated, and the electromagnetic opening / closing valves 22a, 39a are opened to open the patient monitoring device 16a.
Water and a cleaning liquid are supplied to the patient monitoring device 16a.
このようにして患者監視装置16aの洗浄が終了したら、
洗浄用ポンプ35、37の運転を停止するとともに電磁開閉
弁22a、39aを閉鎖し、新たな透析器15aを患者監視装置1

が可能となる。After cleaning the patient monitoring device 16a in this way,
The operation of the cleaning pumps 35 and 37 is stopped, the electromagnetic opening / closing valves 22a and 39a are closed, and a new dialyzer 15a is installed in the patient monitoring device 1.
If it is connected to 6a, it becomes possible to perform dialysis by the dialyzer 15a.
このような洗浄作業は他の患者監視装置16b、16cについ
ても同様に行なうことができ、したがってそれぞれ他の
患者監視装置による透析を防げることなく各患者監視装
置を洗浄することができる。Such a cleaning operation can be similarly performed on the other patient monitoring devices 16b and 16c, and thus each patient monitoring device can be cleaned without preventing dialysis by the other patient monitoring device.

ことができる。Also in this embodiment, when the dialysis work by all the patient monitoring devices 16a to 16c is completed, only the electromagnetic on-off valves 6 and 8 of the A liquid supply source 3 and the B liquid supply source 4 are closed and all other components are closed. By opening the electromagnetic on-off valve and activating all the pumps, it is possible to supply the cleaning fluid and water to the dialysate supply apparatus 1 to wash the dialysate supply apparatus 1, and further to supply the dialysate supply. By supplying the cleaning liquid and water from the device 1 to the patient monitoring devices 16a to 16c, the patient monitoring devices 16a to 16c can be cleaned simultaneously.
なおこの際、第２洗浄液供給源36側のポンプ37を停止さ
