IPC: A61N5/067
Filed: 2019-11-29
Granted: 2020-12-07
Abstract: FIELD: medical equipment.SUBSTANCE: method for non-invasive blood irradiation as well as versions of a device for its implementation consists in the fact that blood irradiation is performed by linearly polarized radiation with orientation of radiation polarization plane perpendicular to the blood flow bed. When irradiation is performed, radiation power losses are reduced when introduced into the blood vessel and a large portion of the introduced radiation is directed along the bloodstream, thereby increasing radiation intensity affecting blood cells. Thus, proposed method and devices for its implementation allow increasing directivity and effectiveness of light exposure on blood cells. Implementation of the method enables reducing the exposure time or reducing the laser energy required to produce a therapeutic effect.EFFECT: implementing the method also reduces radiation exposure on biological tissues located in front of the blood vessel.4 cl, 3 dwg
