DEVICE FOR PHOTODYNAMIC VISUALIZATION FOR DIFFERENTIATION OF LYMPHATIC DRAINAGE PATHWAYS Russian patent published in 2019 - IPC A61B6/00 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment and is intended for photodynamic imaging for differentiation of lymphatic drainage. Device comprises a first infrared radiation unit, the emitter of which is in form of a light-emitting diode, the maximum infrared radiation of which corresponds to 660 nm, SSD-camera with optical filter of the first unit, made with limitation on wave length 760 nm, recorder, unit of visible radiation and second unit of infrared radiation. Each of the units includes a recorder, an emitter, a SSD-camera with an optical filter, wherein the emitter of the visible radiation unit is in form of a ring, radiator of the second infrared radiation unit is made in the form of a light-emitting diode, the infrared radiation maximum of which is equal to 730 nm, the optical filter of the SSD-camera of the visible radiation unit is made with wavelength limitation equal to 640 nm, and the optical filter of the second chamber SSD-camera has a wavelength limit equal to 805 nm.

EFFECT: invention provides higher accuracy of lymphatic drainage differentiation.
