ようにしている。In this type of dialysis machine, the dialysate is supplied with concentrated liquid from the concentrated liquid supply source to the dialysing liquid supply device, and water is also supplied from the water supply source, and the concentrated liquid and water are mixed at a predetermined ratio. We are trying to manufacture. Then, the dialysate produced by the dialysate supply device is distributed and supplied to a plurality of dialyzers connected in parallel, and the dialysate is distributed from the dialysate supply device to each dialyzer using a patient monitoring device installed for each dialyzer. The supply status of each supplied dialysate is monitored.

が終了するまで洗浄を待つ必要があった。"Problem to be Solved by the Invention" By the way, it is common for patients undergoing dialysis to have different dialysis times depending on their medical condition and physical conditions. Even if you start, the end time of each will be different. When dialysis is finished, it is necessary to remove the dialyzer and clean the patient monitoring device, but as mentioned above, with conventional dialysis machines, the dialysate supply device and each patient monitoring device are cleaned at the same time. Because of this, it was not possible to clean only some of the patient monitoring devices, and it was therefore necessary to wait until all patients' dialysis was completed.

望に対応することができなかった。Furthermore, depending on the patient, a thicker dialysate may be desirable, or it may be desirable to add CaC1□ or glucose to the dialysate, but conventionally, the dialysate supply device described above produces a common dialysate for each patient. Therefore, we were unable to accommodate such requests.

である。"Means for Solving the Problems" In view of such circumstances, the present invention provides a method for producing dialysate by mixing concentrated liquid from a concentrated liquid supply source and water from a water supply source in the above-mentioned dialysis apparatus. , a dialysate supply device which is supplied with cleaning fluid from a cleaning fluid supply source for cleaning, a plurality of dialyzers each connected in parallel to this dialysate supply device, and a dialysate supplied from the dialysate supply device to each dialyzer. In a dialysis machine equipped with a plurality of patient monitoring devices that each monitor the supply status of dialysate, a cleaning solution that supplies cleaning fluid to each of the patient monitoring devices separately and without passing through the dialysate supply device. It is possible to selectively connect to a supply source, a water supply source that supplies water, and an auxiliary chemical solution supply source that further supplies an auxiliary chemical solution.

させることができる。"Operation" According to the above configuration, when dialysis by a part of the patient monitoring device is completed, the cleaning fluid and water supply from the cleaning fluid supply source are supplied only to the patient monitoring device without passing through the dialysate supply device. Since water can be supplied from the dialysis fluid supply device and other patient monitoring devices, only the patient monitoring device that has finished dialysis can be cleaned while dialysis work using the dialysate supply device and other patient monitoring devices continues. The operating rate of the device can be improved.

The dialysate is discharged to the outside via the discharge pipe 19, and as a result, the amount of dialysate stored in the dialysate supply device 1 becomes small (if this happens, new dialysate is added to another tank of the dialysate supply device 1). If the dialysate in the tank that is mixed, produced, stored, and in use runs out, the dialysate is continuously supplied from the tank to each dialyzer 15A to 15C.
