  • Apparatus and method for measuring concentration of hemoglobin using photothermal effect
    Patent number: 9594026
    Abstract: The present invention relates to an apparatus for measuring concentration of hemoglobin in blood using a photothermal effect, the apparatus including: a reference light source unit for radiating a reference beam; a photothermal light source unit for radiating a photothermal beam from which the photothermal effect is generated; a cuvette unit for accommodating a collected blood sample thereinto and having first and second reflection layers; and a concentration operation unit for calculating the concentration of hemoglobin by using the phase changes of interference signals generated from the incidence of the reference beam radiated from the reference light source unit onto the first and second reflection layers of the cuvette unit as the photothermal beam radiated from the photothermal light source unit is incident onto the cuvette unit and absorbed by hemoglobin to generate the photothermal effect through the emission of heat.
