Specifically, the position of the total hemoglobin content higher than the preset standard hemoglobin content threshold value in the detection image can be identified by a highlight color, and the corresponding blood stasis severity at the highlight position can be identified. For example, the first preset level information may be set to include a first sedimentation level, a second sedimentation level, and a third sedimentation level for characterizing that the severity of blood sedimentation increases in sequence, and the first sedimentation level is expressed by orange, aiming to alert a user that a slight blood sedimentation symptom exists at a corresponding position; the sedimentation grade II is expressed by yellow, and the purpose is to warn a user that moderate blood sedimentation symptom exists at the corresponding position; the three stages of stasis are represented by red colors, aiming at warning the user that severe blood stasis symptoms exist at the corresponding positions. The positions with the oxygen saturation content lower than the preset standard oxygen saturation content threshold value in the detection image can be identified by preset colors, and the corresponding positions are identified with character information used for representing slight poor circulation, moderate poor circulation and severe poor circulation, wherein the mild poor circulation, the moderate poor circulation and the severe poor circulation are sequentially increased, so that a user can visually determine the skin area with the symptom of poor blood circulation by using the preset color identifiers, and can realize self-diagnosis by the character information, thereby avoiding diseases such as bedsore and the like caused by aggravation of poor blood circulation.

More specifically, the display module can be used for displaying the first warning information and/or the second warning information, so that a user can visually see the unsmooth blood circulation of the local part of the body, and timely treatment is adopted to avoid further deterioration of the state of an illness; in the treatment process, doctors or users can conveniently and accurately judge the subcutaneous tissue treatment condition, and basis is provided for diagnosis and further treatment. Respectively calculating the content distribution of hemoglobin and oxygenated hemoglobin of multispectral image data, further calculating the content distribution of total hemoglobin and the distribution of oxygen saturation, and reconstructing and overlaying the image on an original image for analyzing and evaluating the potential bedsore occurrence risk and evaluating the occurred progress condition; compared with a visible light image, the imaging result of specific wavelength and the combination thereof can extract and highlight the information for diagnosis; the multispectral image data can be automatically identified and obtained through a computer image algorithm, so that the requirements on skills and experiences of operators can be further reduced; medical care and other personnel can quickly, simply and noninvasively carry out body local blood circulation detection in daily nursing of bedridden patients so as to take more reasonable nursing measures and prevent bedsores.
