Abstract

Inventive mrfocurcn for medical technology, specifically for devices for artificial ventilation of the lungs. The purpose of p: to gain and - to reduce the effect of the patient on the patient due to the acceleration of the process of changing the treatment mode of the device. The device contains primary and secondary electrogenerators (ground valves 1 and 2, primary (1Y and additional injectors 4 and 5, separation unit 6, membrane clan 9), controlled exhalation valve 14, mask 15, breathing frequency generator 1 1, high-frequency generator, The main and additional pulse-width modulators. With low gas flow, the main solenoid valve 1 is operated, which is controlled by the main modulator, and at high flow rates two valves 1 and 2 are operated, the latter is controlled by an additional junction lamp. the pulses produced by the modulators determine the flow rate of the gas passing through valves I and 2 into the inspiratory phase. The quick change in the parameters of the pulse-width modulators determines the possibility of the accelerated transfer of the device from one mode to another, 2 or 1 I (L

Description

ABOUT)

The breathing frequency 17 hpkerator 171 generates a right-angle sh-shulsy that determine the phases of inspiration and expiration. The pulses of the generator 17 control the operation of PbiC.oKO4acTOTH (jro of the generator 18, At the time of the impulse of the impulse coming from the output of the generator 17, the generator 18 generates pysoco-pulses (20-30 Hz) impulses. During the negative impulse, nocrynafODie the generator output 17, the pulse generator 18 does not produce. During the inspiratory phase, the generator 18 sends triggering high-frequency pulses to the inputs of the pulse-width modulators 19 and 20, the frequency of the pulses received at 1 outputs of the toros 19 and 20, is determined by resistors 21 and 22 The consumption of gacha passes on through the valves 1 and 2, oprsdelmets pulse duty factor, but with stepping modulators 19 and 20. At gas flow rates mal1,1h operates CBP) OCHOBHOII valve 1 is controlled by a modulator 19. At high gas flow rates also begins to operate and the valve 2.

The CKBJDKHOCTH adjustment of the pulse-width modulators 19 and 20 can be made by variable-1 and resistors 21 and 22 and: n1 be set by a code from an external digital device. Gas portions passing through valve 1 enter injector A, pressurize into the lower cavity of valve 9 and through the non-return valve 8 into separating unit 6. At the same time, the diaphragm of valve 9, under pressure of gas, closes the vent into the atmosphere - the air mixture leaving the injector AJ enters unit 6. The fur 11, placed at 6, is compressed, and the gas mixture containing it through the breathing circuit enters the respiratory system and respirator, an artificial inhalation occurs. During the operation of the valve 2, the mixture supplied to them enters the node 6 through the return valve 11,

In the expiration mode (no valves are applied to valves 1 and 2), the intake of the airless injectors A and 5 stops, the valve 10 of the valve 9 is emptied, the valve membrane 9 is lowered, the air flow from the node 6 into the atmosphere . Fur 11 expands, dialing through yapapan 12 a new porgo (10g, 1h, panienth exhales through the valve in i / ioxa and the atmosphere or B attached ii HHi II to valve 14 hose.
