Abstract:
1. A blood purification apparatus comprising a blood purification instrument comprising a channel for extracorporeally circulating blood of a patient; and a concentration detector for detecting a concentration of liquid flowing during blood purification wherein: the concentration detector comprises: a light emitter for irradiating the channel, through which the liquid is to flow, with light, a light receiver for receiving light from the light emitter transmitted through the channel, a reference light receiver for receiving reference light which has not been transmitted through the channel; a detector for detecting a light intensity respectively of the transmitted light received by the light receiver and a light intensity of the reference light received by the reference light receiver; and an error corrector for detecting the concentration of the liquid based on the light intensity of the transmitted light and for correcting a detection error of the concentration detector based on the light intensity of the reference light.
