Title:
CONCENTRATION MEASUREMENT MODULE, DIALYSIS DEVICE, AND CONCENTRATION CALCULATION METHOD
Document Type and Number:
Japanese Patent JP2017127635
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a concentration measurement module capable of simultaneously measuring concentration of two constituents included in fluid.SOLUTION: A concentration measurement module 70 internally including a casing 1 capable of introducing a body to be irradiated includes: a light source 2 provided outside the casing 1 and allowing output light to impinge on the inside of the casing 1; a first light reception part 3 that includes sensitivity to wavelength of output light of the light source 2 and receives light radiated from the inside of the casing 1; and a second light reception part 4 that has sensitivity to wavelength longer than the first light reception part 3 and receives light radiated from the inside of the casing 1. Based on a first signal outputted from the first light reception part 3 and a second signal outputted from the second light reception part 4, operation of concentration is performed by an operation part 7 to calculate concentration of a first constituent corresponding to the first signal and concentration of a second constituent corresponding to the second signal.SELECTED DRAWING: Figure 1
