Title:
An operating method of a concentration measuring device and a concentration measuring device
Document Type and Number:
Japanese Patent JP6124371
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a concentration measuring device and a concentration measuring method that enable objective determination of whether or not a sternum is pressed appropriately.SOLUTION: A concentration measuring device measures a temporal relative variation (ΔcHb, ΔOHb, or ΔHHb) in at least one of total hemoglobin concentration, oxygenated hemoglobin concentration, and deoxygenated hemoglobin concentration in the head that vary due to repeated pressing of the sternum, the device comprising: a light-input part for inputting a measuring light to the head; a light detection part for detecting the measuring light transmitted inside the head and generating a detection signal corresponding to intensity of the measuring beam; and a CPU14 for obtaining the relative variation (ΔcHb, ΔOHb, or ΔHHb) on the basis of the detection signal.SELECTED DRAWING: Figure 3
