The purpose of the invention is the introduction of aerosols of inhalation fluids.

The drawing shows the proposed device.

The device contains a manostat 1 with an adjustable tube immersion depth in the fluid under the pressure established earlier by the bone, an electronic generator 2 control- enters through the regulator 22 into the input pulses with adjustable split-nozzle 9 of the exhalation ejector, creating at the time of inhalation and expiration, electro-atmospheric pressure in the command pneumatic switch 3, control 23 of the membrane repeater, dilution generator 2, stabilizer 4 pressure-. in the bronchoscope, and if there is a breathing mixture with a pressure gauge in the box, 5

to set the required pressure, two-channel pneumomechanical switch 6 with channels I and II with the control button 7 set in motion

manually, a bronchoscope with 20 outlets built into it, creates in the bronchoscope inhalation nozzles of the injector 8 inhaler, flow from the inhalation injector to the ejector of the ejector 9 expiration, mirror 10, injecting and exhaling preventing the gas from entering rum 11 of the liquid, membrane repeater 12 pressure, burette 13, placed in thermostat 14, check valve 15, pressure rating 23, set by manostat, is the required overpressure. Through the regulator 19 and the check valve 15 oxygen with the required flow enters the inlet nozzle 8 of the inhalation injector and,

and spraying of bleed on the face to the bronchologist. The check valve 15 prevents the oxygen supply in the inspiratory phase from the inlet

sat down 16–22, the command chamber 23 and the con- of the nozzle 8 of the inhalation injector to the inlet nozzle 24 of the relief unit filled 12 pressure.

The device works as follows.

The bronchoscope tube was inserted into the respiratory tract of the patient under the narlo 9 expiratory ejector.

When the device operates in the manual mode in the event of a generator failure or an electropneumatic switch. Oxygen from the source of compressed., Tel, as well as at the discretion of the bronchologist,

air through the regulator is fed to the inlet of the pressure regulator 4, from the output of which, under the required adjustable pressure, oxygen is fed to the input of the electropneumatic switch 3, to the norbronchologist, acting on the button 4 of the pneumomechanical switch 6, can alternately supply oxygen to the inlet nozzle 8 of the inspiratory injector or on the inlet nozzle 9 of the ejector

Minimally closed inlet A of the channel is pneumatic with expiration. In this way, a mechanical switch 6 is provided through the ventilation of inhalation and exhalation. At the same time, wiping 16 - on a normally open injection of fluid in the inspiratory phase

Input G channel of the same switch 6, and provides the opportunity to work under

as well as through the throttle 18, it is supplied with direct pressure.

Manostat pressure tube 1. The device ensures safety

The depth of immersion of the tube in the manostat, 40 patients and the ability to work in a discharged, for example, with water, provides - personal modes, both automatic and

with the required pressure in the command cavity 23 of the membrane repeater 12 pressure. When the device operates in automatic mode, in the inspiratory phase, an electronic generator 2 receives a pulse, an electropneumatic switch 3, the output A of which opens and oxygen enters the normally open input B of the mechanopneumatic switch, the output of which through regulator 19 is connected to the injector 8 nozzle through a valve 17 — with a gas inlet of a burette 13 and with an outlet of a non-return valve 15. A jet of pressurized air is injected into the bronchoscope, while the flow rate is handheld, it allows automatic injection Drugs in the respiratory tract and moistening of the respiratory system during its work with an optical telescope; perform artificial ventilation under constant positive pressure, reduce trauma to the respiratory tract mucosa.

Invention Formula A device for artificial ventilation of the lungs during bronchoscopy, comprising a bronchoscope with a tube, a mirror, an inhalation injector and an expiratory ejector with nozzles, is injected with pressure using stabilizing and ejection gases and a pressure chamber 4 and a regulator 19 and mixing mixtures, The pressure stabilizer breaths. Simultaneously through the valve 17, the pressure of oxygen is squeezed out by the liquid, the generator of control pulses, the gas flow switch, the throttles. bone from the burette 13 through the regulator 21 and the injector 11 into the bronchoscope. The thermostat 14 sets the perurature of the fluid. The valve 16 is automatically closed. In the expiratory phase, the pulse from generator 2 does not flow, the output A of the electro-pneumatic relay 3 closes, the output B opens and through the normally open input G of the channel 11 of the pneumomechanical switch 6 oxygen under the previously set pressure flows through the regulator 22 to the inlet nozzle 9 of the expiratory ejector creating at atmospheric pressure in the command chamber 23, the membrane repeater is diluted in the bronchoscope, and in the case of the presence of gas under the pressure established earlier, flows through the regulator 22 to the inlet nozzle 9 of the ejector oha, creating at atmospheric pressure in the command cavity 23 a membrane repeater, a rarefaction in the bronchoscope, and in the case of  exit from it, creates in the bronchoscope flow from the inhalation injector to the ejector of exhalation, preventing the ingress of gas The pressure set by manostat is 23, the required overpressure. Through the regulator 19 and the check valve 15 oxygen with the required flow enters the inlet nozzle 8 of the inhalation injector and, exit from it, creates in the bronchoscope flow from the inhalation injector to the ejector of exhalation, preventing the ingress of gas and spraying of bleed on the face to the bronchologist. The check valve 15 prevents the oxygen supply in the inspiratory phase from the inlet nozzle 8 of the inspiratory injector to the inlet nozzle 9 of the exhalation ejector.
