  • Chemiluminescence analyzer, blood purification apparatus, and blood purification system
    Patent number: 11156557
    Abstract: A chemiluminescence analyzer includes a reactor to cause waste liquid discharged from a blood purification apparatus to react with a reagent solution, a photodetector to measure an intensity of chemiluminescence arising in the reactor, a first liquid conveyor to convey the waste liquid from a waste liquid passage of the blood purification apparatus to the reactor, and a second liquid conveyor to convey the reagent solution to the reactor. The chemiluminescence analyzer further includes a liquid mixture passage extending from the reactor to convey a liquid mixture including the waste liquid and the reagent solution after reaction, a joint to couple the liquid mixture passage to the waste liquid passage of the blood purification apparatus, and an electric interface for connection with an external device.
