FIELD: medicine; medical engineering. SUBSTANCE: method involves tightly sealing the nasal and rhinopharyngeal cavity with soft palatine that is pressed against the posterior pharyngeal wall by contracting respiratory muscles without performing exhalation at the first stage. Rarefaction to 60-85 kPa is created in nasal cavity and rhinopharynx that is equalized 5-15 s later by supplying air under atmospheric pressure. The second stage involves tightly sealing the nasal and rhinopharyngeal cavity for 10-15 s, sucking air and nasal cavity matter from one nose half off and supplying aerosol containing medicament into the other half under pressure higher than usual. The third stage involves tightly sealing the nasal cavity and rhinopharynx and reducing pressure to 60 kPa via the other half of the nose opposite to one in sinuses of which medicament is to be supplied. 1-2 s later, aerosol containing medicament is introduced into the injured half of nose under pressure of 140 kPa. The pressure is dropped to 80 kPa after having done sealing and quickly equalizing it with atmospheric pressure by supplying air or aerosol containing medicament into the other nose half under pressure of 120 kPa at the fourth stage. When needed, each stage is to be repeated using obturator. Pressure reduction or increase is carried out by the same value. Device has suction line having rarefaction source, reservoir for accumulating exudate, connection tube and delivery line having pressure source and connection tube. The suction line additionally has obturating olive, filter, vacuum manometer, distributor unit, receiver, vacuum-gage and rarefaction regulator. The obturating olive is connected to rarefaction source via the connection tube mounted in series, reservoir for accumulating exudate, filter, distributor unit, receiver and rarefaction regulator. The vacuum manometer is mounted between the receiver and rarefaction regulator. The delivery line additionally has pressure control unit, manometer, receiver, dosing unit, obturating olive and sprayer. Pressure source is connected to the obturating olive via pressure control unit, receiver, distributor unit, connection tube and sprayer connected in series. The manometer is mounted between the pressure control unit and receiver. The dosing unit is connected to the sprayer. EFFECT: improved quality of pathological content evacuation from nasal appendage sinuses; facilitated medicament delivery to the nasal appendage sinuses. 5 cl; 2 dwg
