IN VITRO PHOTODYNAMIC EXPOSURE DEVICE Russian patent published in 2023 - IPC G01N33/48 

FIELD: medical devices.

SUBSTANCE: proposed device for studying photodynamic effects in vitro includes a multi-well plate for culture studies with a transparent bottom and/or a lid, containing liquid with photosensitized bioobjects in some of the wells, and at least one light source with a wavelength in the absorption band of the photosensitizer, emitting a collimated the beam of light, additionally contains a light-guide multi-fiber randomized bundle and a quoting unit, in which the input end of the bundle the input end of the bundle is fixed in such a way that its optical axis forms an angle of 0°≤α≤25° with the optical axis of the light beam of the light source, the output end of the bundle is fixed orthogonally to the tablet at a distance from its surface, at which the beam emerging from it irradiates the entire part of the tablet, the wells of which contain liquid with photosensitized biological objects.

EFFECT: proposed device provides uniform irradiation of the plate with photosensitized biological objects, which improves the accuracy of research.
