Problems solved by technology

The existing quantitative analysis of these two physiological indicators can only be done through blood tests. The disadvantages are: long detection cycle, increased pain for the test object, etc., and cannot quantitatively describe the distribution of oxygenated hemoglobin and deoxygenated hemoglobin
[0009] However, at present, the quantitative analysis of the above two indicators is mainly through blood tests. The technical disadvantages are: there are disadvantages such as long detection period and increased pain for the testers, and it is impossible to analyze the content distribution of oxygenated hemoglobin and deoxygenated hemoglobin in human tissues. make a quantitative description

Abstract

The invention relates to a device for quantitatively detecting the spectral content distribution of oxygenated hemoglobin and deoxygenated hemoglobin. The device comprises a light source module, an imaging module, an adjusting bracket, an image data transmission link, a control command transmission link and a computer. As a technical means of high spectral imaging is adopted, the full cover detection is realized in a detected region, and a characteristic spectrum of the oxygenated hemoglobin and the deoxygenated hemoglobin is extracted through using a spectral decomposition technology, the calculation is carried out by utilizing a regional oxygen saturation computational formula, and the device and the method have the characteristics of acquiring comprehensive information and being high in precision without any reagent.

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...
