Description

technical field

[0001] The invention relates to a quantitative detection device and method for spectral content distribution of oxygenated hemoglobin and deoxygenated hemoglobin, belonging to the technical field of biomedical engineering. technical background

[0002] Hemoglobin is an important part of blood cells that is responsible for transporting oxygen from the lungs to other tissues in the body. Oxygenated hemoglobin content and deoxygenated hemoglobin content are two important physiological indicators. Existing quantitative analysis of these two physiological indicators can only be done through blood tests. The disadvantages are: long detection cycle, increased pain to the test subjects, etc., and cannot quantitatively describe the distribution of oxygenated hemoglobin and deoxygenated hemoglobin.

[0003] Oxygenated hemoglobin and deoxygenated hemoglobin have different absorption characteristics in the visible and near-infrared spectral ranges, deoxygenated hemoglob...
