METHOD FOR TREATMENT OF PATIENTS WITH TROPHIC ULCERS Russian patent published in 2017 - IPC A61B18/02 A61M1/00 A61K33/14 A61P17/02 

FIELD: medicine.

SUBSTANCE: ulcer surface is treated with a tampon moistened with saline. Single cryogenic action with liquid nitrogen with a temperature of -180°C and exposure time max. 5 seconds is performed, by the maximum cooled applicator with different diameters of flat working surface. Three to six days after cryoexposure, the formed layer of the affected tissue is removed by hydropressive treatment of ulcer with an ultrahigh-pressure microdispersion fluid stream with an outlet pressure of 120-150 atm, from a distance of 15-20 cm from the nozzle system end to the ulcer surface, at an angle of 40-45° relative to the ulcer surface. In this case, if the ulcer significantly exceeds the applicator surface, the latter is progressively moved to cover the entire surface of the wound, without staying at each site for more than 5 seconds.

EFFECT: method allows to shorten the time for trophic ulcers preparation to active closure by skin grafting or application of collagen-containing drugs, eliminates perifocal inflammation and reduces the risk of infectious process development.
