DIALYSIS MACHINE CLEANING METHOD AND DIALYSIS MACHINE CLEANING WASTE NEUTRALIZER

To provide a cleaning method for dialysis machines that facilitates the work of installation and can neutralize dialysis waste fluid to within sewer standards without the use of a special neutralizer.SOLUTION: A method for cleaning a dialysis machine in which waste fluid from cleaning a dialysis unit is neutralized and then discharged, comprising an acid washing step in which waste fluid from acid washing is sent to an acid reservoir, an alkali washing step in which waste fluid from alkali washing is sent to a waste fluid reservoir, a water washing step in which waste fluid from water washing is sent to a discharge tank, and a pause step in which, after completion of the water washing step, pumping is stopped in preparation for the start of another dialysis operation. The system performs a waste fluid reservoir level control to start pumping waste fluid discharged from the dialysis unit from the waste fluid reservoir to the discharge tank when the level of the waste fluid reservoir becomes L0 or higher, and a discharge tank level control to start discharging the waste fluid from the discharge tank to the sewage system when the level of the discharge tank becomes L1 or higher. At the start of the alkaline washing step, the waste fluid is discharged from the discharge tank to the sewage system until the liquid level in the discharge tank becomes L3 or lower.SELECTED DRAWING: Figure 4 【課題】設置作業が容易で特別な中和剤を用いることなく下水道基準の範囲内に透析排液を中和処理できる透析装置の洗浄方法を提供する。【解決手段】透析ユニット洗浄排液を中和した後に放流する透析装置の洗浄方法であって、酸洗浄排液を酸貯留槽に送る酸洗浄工程と、アルカリ洗浄排液を排液貯留槽に送るアルカリ洗浄工程と、水洗浄排液を放流槽に送る水洗工程と、水洗工程の終了後に送液を休止して、他の透析操作の開始に備える休止工程とからなり、排液貯留槽の液面レベルがＬ０以上となったときに、透析ユニットから排出された排液の排液貯留槽から放流槽への送液を開始する排液貯留槽レベル制御と、放流槽の液面レベルがＬ１以上となったときに、排液の放流槽から下水道への放流を開始する放流槽レベル制御とを実施し、アルカリ洗浄工程の開始時に、放流槽の液面レベルがＬ３以下となるまで排液を放流槽から下水道に放流する透析装置の洗浄方法。【選択図】図４
