FIELD: medicine.
SUBSTANCE: invention relates to medical equipment. Device for delivering solutions in the form of an aerosol into the anatomical cavities includes a body, inside which there is an extension tube, at one end of which there is a shank, which is adapted to be connected to a high pressure pipe for supplying a solution to the device. Other end of the extension tube is in communication with the liner channel and a valve is provided therein, consisting of a spring with a stopper fixed at its proximal end, made of an elastic material capable of providing a seal. Liner channel is communicated with a nozzle channel in which a swirler is provided consisting of a metal cylinder with a mushroom-shaped base on the proximal edge intended to support the spring, and two parallel grooves in the form of truncated parallelepipeds. Swirler has the ability to convert the laminar flow of the solution into two counter-directed turbulent flows with the formation of an aerosol after a counter-tangential collision. Nozzle at the end has a nozzle for the exit of the aerosol.
EFFECT: technical result consists in preventing the solution from falling into the droplet cavity when the pressure drops below the required pressure to produce an aerosol.
