A blood purification device for blood purification therapy performed through a blood purifier, the blood purification device includes piping; a plurality of sensors of different detection types that are provided on the piping; and a liquid chemical identification unit that identifies a type of a cleaning/disinfection liquid chemical flowing through the piping by using the plurality of sensors. The liquid chemical identification unit is configured to be able to identify types of the liquid chemicals of at least not less than the number of the plurality of sensors by using the plurality of sensors.

Blood purification device

A system and a solution-preparation-determining apparatus which determines whether additional preparation of an undiluted dialysate solution is necessary. A blood purification system includes a solution-preparing unit that prepares an undiluted dialysate solution, a dialysate-supplying unit that prepares a working dialysate at a predetermined concentration by diluting the undiluted dialysate solution received from the solution-preparing unit, a blood-purification-treatment section that includes a blood-purification-apparatus group including at least one blood purification apparatus that performs blood purification treatment in which the working dialysate is supplied to the blood-purification-apparatus group, and a determining unit that determines whether additional preparation of the undiluted dialysate solution is necessary from a result of comparison between an estimated number of treatment sessions expected to be performed by the blood-purification-apparatus group throughout a predetermined period and an actual number of treatment sessions performed by the blood-purification-apparatus group as of a time point during the predetermined period.

Blood purification system and solution-preparation-determining apparatus

A blood purification apparatus that is capable of, with no preparatory operations, performing substitution by supplying dialysate in a dialysate introduction line to a blood circuit during ultrafiltration treatment, or performing blood return by immediately supplying the dialysate in the dialysate introduction line to the blood circuit after the ultrafiltration treatment. A blood purification apparatus includes a dialyzer, a dialysate introduction line, a dialysate drain line Lthrough which drain liquid from the dialyzer is drained, and an ultrafiltration pump capable of removing water from the blood in the blood circuit. The blood purification apparatus is capable of performing substitution or blood return by supplying the dialysate in the dialysate introduction line Lto the blood circuit. In an ultrafiltration treatment in which the ultrafiltration pump is activated while the introduction of the dialysate into the dialyzer is stopped, dialysate delivery is performed while the introduction of the dialysate into the dialyzer is prevented.
