METHOD AND DEVICE FOR PATIENT ANATOMICAL PROPERTIES DETERMINATION Russian patent published in 2017 - IPC A61B5/107 

FIELD: medicine.

SUBSTANCE: method comprising the following steps: projection of at least one structured light structure in the patient's mouth, detection of at least one reflected light structure, at that, each of the said reflected light structures occurs as a result of reflection of the corresponding projected structured light structure, analysis of at least one structured light structure reflected from the viewpoint of at least one structured light structure, thus defining the patient's anatomical features, wherein each of the at least one structured light structures comprises a set of predetermined patterns of parallel lines, so that the predetermined set of parallel lines defines a structure comprising areas with increased line thickness and areas with reduced line thickness, and/or contains areas with increased line thickness and areas with a reduced line thickness, and their projections correspond to the predetermined locations in the oral cavity and throat, including polarization of the structured light structures prior to reflection in accordance with the first polarization mode, and polarization of the reflected light structures prior to detection in accordance with the second polarization mode, wherein the first and second polarization modes are opposite. The image forming device includes a projection means, a detection means, an analysis means, the first polarization means for structured light structure polarization prior to reflection in accordance with the first polarization mode and the second polarization means for reflected light structure polarization before and after reflection in accordance with the second polarization mode.

EFFECT: use of inventions allows to improve the accuracy and simplify patient's condition monitoring regarding sleep apnea.
