X-RAY DIAGNOSTIC TECHNIQUE FOR OPEN RETENTION CYSTS OF TRACHEAL AND BRONCHIAL EXCRETORY GLANDS Russian patent published in 2014 - IPC A61B6/00 A61K49/04 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, pulmonology, and roentgenology. An X-ray diagnostic technique for open retention cysts of the tracheal and bronchial excretory glands consists in administering a contrast agent into dilated excretory ducts of the cysts. The contrast agent is presented by an air-powder aerosol of a bioinert material with particles of the diameter less than 1 mcm. Active inhalation provides the particles motion into each cyst through the excretory duct and the particles deposition on the cyst walls to visualise in such a way the presence thereof. The bioinert material is presented by tantalum, a powder of which is placed into a container coupled with PAI-2 portable aerosol inhaler comprising a compressor. An air spray is generated to activate the powder and to form the air-powder aerosol to be supplied through a catheter into the excretory ducts of the open retention cysts of the tracheal and bronchial excretory glands.

EFFECT: method provides accurate and reliable X-ray diagnosis of specific formations of the tracheobronchial tree - open retention cysts of the tracheal and bronchial excretory glands.
