Description

I

The invention relates to medical technicians intended for the treatment of the respiratory tract and lungs heated by aerosols and electrical aerosols of medicinal substances.

The known generator of electrical aerosols containing an ejector nozzle / heater inducing electrode 1} However, the lack of means for stabilizing the temperature of the aerosol determines the insufficient effectiveness of therapy with a known generator.

The purpose of the invention is to ensure the stability of the parameters of the aerosol while increasing the electrical safety of the patient and the medical staff. This goal is achieved by the fact that the generator is equipped with an electric aerosol generation mode indicator, a separator and a temperature stabilizer, and the inducing electrode is filled in the form of coaxially arranged cylinder rods with a hole, the outer side surface of which has a die formed by their ends. the cavity through the hole in the cylinder is in communication with the atmosphere, while the inducing electrode is electrically connected to the indicator of the mode of generation of the electroaerosol And installed between a separator and an ejection nozzle, pneumatically coupled to a temperature stabilizer, electrically connected to a heater and an electroaerosol generation mode indicator. Moreover, the temperature stabilizer is made in the form of kinematically connected between

10 a membrane, relay and switch. In addition, for the purpose of smooth control of the dispersion composition and bulk density of the electric charge of the inhalation aerosol, the separator

 5 is made in the form of two perforated rings mounted with the possibility of reciprocal movement.

kinematically interconnected membrane relay 9 and switch 10, as well as an indicator 11 of the mode of generation of electroaerosol. The outer, lateral surface of the rod 4 and the cylinder 5 has an electrical insulation protruding beyond their ends, and the annular cavity formed by them through the cylinder opening 6 communicates with the atmosphere. The induction electrode 3 is electrically connected to the indicator 11 for generating an electrical aerosol and is installed between the separator 7 and the forked injector 1 pneumatically connected to a temperature stabilizer 8 that is electrically connected to the heater 2 and the indicator 11 for the generating of an electro-aerosol. -. .

The generator of electrical aerosols works as follows.

Medicinal liquid is poured into cup 12. Compressed gas flows. the inlet nozzle 13 of the preformer 1 and the control channel 14 мемб membrane relay 9 of the temperature stabilizer 8. The force of the membrane relay 9 is kinematically transmitted to the switch 10, which, after actuation, connects the heater 2 to the electrical network. If the indicator 11 is included in the network, as indicated by the light from the lamp 15, the lamp 16 lights up, signaling the operation of the heater 2.

Compressed gas, having exhausted from the air nozzle 17 when the channel 18 is closed, creates in the ejection nozzle 1 a vacuum, under the influence of which the medicinal substance / gvo from glass 12 goes through pipe 19 through tube 19 to the nozzle 1: ejector 21. Under the influence of the vacuum generated by the electrode 21, atmospheric air is sucked through the opening in the body of the heater 2 and, after passing through its labyrinths, is heated. The passage through the cavity of the inner cylinder 221, the warm air heats the medicinal substance in the annular chamber of the glass 12, and through the channel 23 enters the ejector 21, where it is mixed with the aerosol and through the nozzles 24 enters the patient. The nebulized liquid and the precipitated large aerosol particles through the channel 25 are returned back to the beaker 12.

For a smooth change in the dispersion and bulk density of the electrical aerosol charge, an aerosol is produced.

relative movement of perforated separator rings 7.

. Thus, the heater 2 is turned on only if there is a compressed gas in the gas nozzle 17, at which the ambient air is constantly sucked through the heater 2, maintaining the aerosol temperature within permissible limits. As a result of this shutdown, the aerosol parameters are stable while increasing the electrical safety . and medical staff.
