摘要：
PROBLEM TO BE SOLVED: To provide a method of diagnosing a dialysate preparation apparatus which does not require a special reagent or equipment for diagnosing a concentration measurement means and permits a diagnosis to be carried out easily, and a dialysate preparation apparatus.SOLUTION: The dialysate preparation apparatus 1 includes a water-supply passage 2, an A liquid passage 3 supplying an A liquid, a B liquid passage 4 supplying a B liquid, and first to third concentration measurement means 20, 23 and 27 and is designed to prepare a dialysate by mixing clear water, the A liquid and the B liquid at a prescribed ratio and measure the concentration of the prepared dialysate by the concentration measurement means. Before preparing the dialysate, the apparatus supplies the B liquid to the water-supply passage from the B liquid passage and causes the B liquid alone to flow in the water-supply passage with the dialysate and the A liquid not flowing in the water-supply passage and measures electric conductivity of the B liquid by first to third detection sections 20a, 23a and 27a of the first to third concentration measurement means and compares the measured electric conductivity of the B liquid with a preset value and then diagnoses the accuracy of the first to third concentration measurement means. This invention does not require a special reagent or equipment and permits the concentration measurement instrument to be easily diagnosed.COPYRIGHT: (C)2013,JPO&INPIT【解決手段】 透析液調製装置1は、給水通路2と、A液を供給するA液通路3と、B液を供給するB液通路4と、第1~第3濃度測定手段20、23、27とを備え、上記浄水、A液、B液をそれぞれ所定の割合で混合して透析液を調製し、該調製した透析液の濃度を上記濃度測定手段によって測定するようになっている。上記透析液を調製する前に、上記給水通路に透析液およびA液が流通していない状態で、上記給水通路に上記B液通路からB液を供給して、上記給水通路にB液だけを流通させ、上記第1~第3濃度測定手段第1~第3検出部20a、23a、27aにより上記B液の電気伝導度を測定して、測定したB液の電気伝導度を予め設定した値と比較することにより、これら第1~第3濃度測定手段の精度を診断する。【効果】 特別な試薬や機器等を必要とせず、簡易に濃度測定装置の診断を行うことができる。【選択図】 図1
