METHOD FOR LOCAL TREATMENT OF INFLAMMATORY DISEASES OF UTERINE CAVITY AND DEVICE FOR IMPLEMENTING IT Russian patent published in 2015 - IPC A61N7/00 A61M31/00 A61K31/345 A61P15/00 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medicine and medical equipment, namely to obstetrics and gynaecology, and can be used for the local treatment of inflammatory diseases of the uterine cavity. The method is implemented by inserting a waveguide of a presented device in a protection enclosure into the uterine cavity. A taper base of a narrow portion of the enclosure leans on an external orifice of the cervical uterus to prevent accidental perforation of the uterus. An infusion system regulator is used to set the spray supply of a therapeutic solution into an irrigation canal of the ultrasonic device. Thereafter ultrasonic vibrations are generated, and the uterine cavity is treated with the sounded therapeutic solution. The exposure length is 3-5 minutes at the ultrasonic vibration frequency of 25 kHz, infusion rate approximately 100-150 ml/min. The total infusion volume is not less than 300 ml. The ultrasonic treatment enables providing the continuous outflow of the uterine discharge. The device comprises an US generator, an acoustic assembly, the waveguide with the protection enclosure, the infusion system for the therapeutic solution supply. The acoustic assembly and waveguide comprises the irrigation canal. A working tip of the waveguide represents a short cylinder having a diameter greater than the rest portion. The irrigation canal of the waveguide has a diameter of 2 mm. The protection metal thin-wall enclosure has a crimped distal end and drain holes and represents two cylindrical elements of various diameters connected by a taper junction with milled grooves arranged so that to enable the fluid access to the working tip cylinder, the length of which makes no more than 3 mm.

EFFECT: inventions provide the effective cleansing of the uterine cavity from infected and necrotised tissues with improved comfort and safety of the procedure with using no endoscopic equipment, cervical dilation manipulations and uterine pre-probing.
