  • Patent number: 12061192
    Abstract: A cholesterol measurement device includes a measuring instrument body; and a light-intensity check member mounted on and integrated with the measuring instrument body. The light intensity check member reflects light emitted from a light-emitting unit, allowing detecting abnormal light intensity and accurate assessing light intensity change, which prevents a measurement value change due to the change in light intensity and improves reliability of the measurement value. The device keeps a measurement unit clean all the time since the measurement unit can be easily cleaned by separating a strip fixation unit, when a specimen flows into the strip fixation unit in which a measurement strip is inserted.
