Title:
透析機械の血液回路における血液のヘモグロビン濃度(HGB)を測定する測定装置
Document Type and Number:
Japanese Patent JP4242652
Kind Code:
B2
Abstract:
A method for measuring the hemoglobin concentration in the blood in a circuit of a dialysis machine includes directing electromagnetic waves against one section of the circuit, measuring values of the electromagnetic waves transmitted through the section, and determining values of absorption of electromagnetic waves by the blood along the section from the measured values of transmitted electromagnetic waves. The values of absorption are correlated with the values of the hemoglobin concentration. The method also includes measuring the values of at least one physical quantity of the blood, wherein the at least one physical quantity is selected from blood pressure and blood temperature, and calculating the values of hemoglobin concentration as a function of the values of absorption and the at least one physical quantity.
