BLOOD COMPONENT QUANTITATIVE METER

摘要

PURPOSE:To obtain a blood component quantitative meter with limited adverse effect due to variations in the flow velocity, by arranging an electrode for detecting interfering substance inserted into a passage, an electrode for detecting substance to be inspected and a flow velocity detection means for detecting and outputting the flow velocity of a sample flowing through the passage. CONSTITUTION:A sensor section 34 is made up of an electrode 38 for detecting interfering substance and an opposed electrode 39. A sensor 34' is made up of an electrode 37 for detecting substance to be inspected and an opposed electrode 39'. Both the sensor sections 34 and 34' are connected to constant voltage generation circuit (battery) 20 and 20 through current/voltage conversion circuits 40 and 40. An operational control circuit 27 sends data for the detected electricity value (digital value) (a) of the substance to be inspected and the detected electricity value (digital value) (b) of the interfering substance to a time detection circuit and data at the elapsed time T as obtained with the time detection circuit corresponding to the flow velocity is inputted to output a computed value S to a display section 28.
