SU381353A1 - DEVICE OF ARTIFICIAL VENTILATION OF THE LUNGS - Google Patents

Description

one

The device: - artificial ventilation of the lungs, containing blocks that set the generator, pneumorele, adjustable throttle and preset, and - the unit of connection to the breathing chamber, rail, 1 injector, reducer and control panel.

The possibility of carrying out artificial ventilation of the lungs both with oxygen-air mixture of any concentration, and with pure oxygen and anesthesia on pure oxygen is ensured by the fact that the device is equipped with a control throttle with an oxygen percentage indicator in the inhaled mixture and a toggle switch, and a toggle switch connected to the output nipple of the pneumatic relay with a spring and an adjustable throttle, pneumatically connected to the suction nipple of the injector, performed by the 1st In the form of a camera installed in its a the atmospheric orifice is a non-return valve, and the generator of the master unit is made in the form of a three-membrane relay, turned off by a negative circuit, and an aperiodic link.

The drawing shows the schematic diagram of the proposed apparatus containing the master unit /, the unit 2 connecting the patient’s respiratory tract, the injector 5, the gearbox 4. the volume absorber 5 turning on the apparatus.

To ensure that) provide inspiratory oxygen-air cNrec.4 any

concentrating, as well as conducting the pressure valve 1 and the lungs: and anesthesia with pure oxygen, the device is equipped with a toggle switch 6 connected to the output fitting 7 of the pneumatic relay 8 with spring 9, adjustable throttle 10 with an indicator of the percentage of oxygen in the inhaled mixture associated with the toggle switch m 6 And the suction fitting 11 and; black 3.

The suction fitting 11 is made in the form of a chamber 12 with an opening 13, which communicates the chamber 12 with atmospheric pressure.

In the atmospheric hole 13, a reverse clan is installed, for example, a fungal clan.

The insulator 3 during inhalation can draw air from the atmosphere through the opening 13 and the valve 14, or oxygen from the reducer 4 through the open toggle switch 6, the throttle 10} fitting 7. Reduction of oxygen consumption and simplification

the design of the apparatus is achieved by that. that the generator of the master unit / is made in the form of a three-liter diagonal pneumatic relay 15 consisting of a furniture system M, nozzles 17.18, control chambers 19 and 20 and output connectors 21 and 22. The upper nozzle 17 is connected to the gearbox 4, the lower nozzle 18 - with a choke 21, and choke 22 with an atmosphere; the aperiodic link was made in the form of adjustable throttles about and a tank 24, moreover, the connection was made with a nozzle 18. With a capacity of 24 p

control camera 20; The target is made in the form of a constant throttle 25, connected to the gearbox 4, and a variable throttle 26 connected to the throttle 25, the control chamber 19 and the atmosphere.

For supplying "compressed oxygen" to the inlector .3 there is a three-membered pneumatic relay 8 with a spring 9, containing a nozzle 27, a system of membranes 28, a control chamber 29 and an outlet nozzle 7, the nozzle 27 being connected to a gear 4, and a control The gauge, measure 29 - with the output fitting 21 of the pneumatic relay 15.

A throttle 30 is used to adjust the minute ventilation. It is connected to the outlet nozzle 7 / pneumatic relay 8 and the injector 3, the output of which is connected to the patient's airway connection unit 2, containing the respiratory trap 30 g and the non-reversible valve 32.

Inspiratory pressure is limited by safety valve 33.

The device works as follows.

The acid from the cylinder through the open-toggle switch 5 enters the gearbox 4 and the passage through the setting unit. made in the form of a combination of chokes 25 and 26, creates in the control chamber 19 of a pneumatic relay 15 a backpressure pressure. Thus, the system of membranes 16n ' relay 15 is in the lower position. Due to this, the upper sollo 17 opens, and the gas from the reducer 4 enters the control chamber 29 of the pneumatic relay 8 and converts the memera system. 29 into (Lower position. The oxygen ACCESS from the reducer 4 opens through the open con.io 27 relay 5. And choke 30 adjustment of the MINUTE ventilation to the injector 3 and then through the lighter body valve and the non-reversible valve 32 to the patient. Inhalation begins.

With artificial ventilation of the lungs with a minimum concentration (35%), the toggle switch is closed, and the injector 3 pushes air from the atmosphere through the opening 13 and the check valve 14. When you need more oxygen, the toggle switch 6 turns on and the throttle 10 settles on the required percentage of K-oxygen in the inhaled mixture. With a fully open 10 oTOiK choke of oxygen, the check valve 14 closes and artificial ventilation is performed with pure oxygen.

The flow of hydrogen flowing through the open nozzle 17; the pneumatic relay 15 starts filling the tank 24 through the choke 23 regulating the breathing 4iacTOTy and. The tank 24 is filled until the pressure in the chamber 20 of the pneumatic relay 15 becomes greater than the pressure in the chamber 19 of the relay 15 by the amount of the differential of the relay 15. The membrane system 16 of the pneumatic relay 15 goes to the upper position. The pressure from the chamber 29 of the pneumatic relay 3 is released into the atmosphere through the open bottom nozzle 18 of the pneumatic relay 15, the spring 9 of the relay 8 closes the gas supply to the injector 3. The inhale ends, the patient exhales to the atmosphere through the non-reversible valve 32.

Passive expiration begins, during which the capacity: 2 is emptied through the open bottom nozzle 18 of the pneumatic relay 15

and choke 23 to the atmosphere. Emptying of the container 24 occurs until the pressure of the overpressure in the chamber /.9 of the pneumatic relay J5 becomes higher than the pressure in the chamber 20 of the pneumatic relay 15.

The J6 membrane system goes down. The cycle is repeated. The ratio between the inspiratory and expiratory phases is controlled by the choke 26.

Subject and reference to the. M and

1. Aeiarat artificial ventilation of the lungs, containing the master unit in the form of a generator, and more effective throttle

and setter, and the unit for attaching to the patient's respiratory tract, injector, reducer control panel, characterized in that, in order to perform artificial ventilation of the lungs as an oxygen-air mixture

of any concentration, as well as clean oxygen, and the possibility of narcosis. With pure oxygen, it is equipped with a regulating choke with an indicator of the percentage of oxygen in the inhaled mixture and a volume bluer connected to the output fitting of the pneumatic relay with a spring and adjustable choke, pneumatically connected connected with the suction nozzle, m of the injector, made in the form of a chamber with a valve installed in its air outlet. 11 return valves, generator
