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.

Abstract: A measuring apparatus includes a light receiving device, a housing, an optical window, an electrical connection line, and a line enclosure. The light receiving device receives light and output a signal. The housing, made of a conductive material, covers the light receiving device. The optical window transmits the light. The optical window includes a conductive part having conductivity. The electrical connection line transmits the signal. The line enclosure is disposed around the electrical connection line and electrically connected to the conductive part and the housing.
