Description

The invention relates primarily to medicine and concerns the respiratory systems, such as, for example, the delivery of anesthetic gas or oxygen to the human lungs.

Respiratory systems are known that contain a closed conduit connected to a mask or mouthpiece, a device for gas-firing, an exhaust valve with a saddle and a closing element and an absorber of carbon dioxide. Such respiratory systems do not provide optimal patient breathing conditions.

The purpose of this invention is to ensure the transfer of force to the closing element of the exhaust valve, depending on the pressure existing in the system to close it at an excess gas pressure in the system that exceeds the predetermined pressure value during compression of the elastic tank. This goal is achieved by the fact that the respiratory system is equipped with a movable TOIM element, a power transfer device and an elastic tank located behind the exhaust valve relative to the direction of gas movement.

In addition to this, for almost all of the gas that has leaked out of the elastic tank is not placed

the pipeline to the exhaust valve; the closed pipeline can be equipped with a one-way valve located behind the exhaust valve, but in front of the moving element and the flexible container. It is advisable to equip the closed pipeline between the branch to the patient and the discharge valve with a throttling device in the form of a nozzle or a drag, which will ensure a delay in the transfer of gas pressure but from the elastic container to the discharge valve. In order to ensure that the system operates with the force developed by the expansion of the movable element, it is advisable to provide the valve assembly with inlet and outlet orifices and a fitting on which the elastic container is fixed, covering the element with an equalizing device, connecting the movable element and a lever. If you equip the lever with a metal plate with a magnet mounted on the opposite side of the load arm, this will ensure that the magnet is so strong that the excess pressure in the valve body exceeds the load. To transfer gas from one chamber through the valve to another (measure, which opens the openings of the elastic tank and the moving element, the valve body can be separated by a single-acting valve of the individual chambers. Fig. 1 schematically shows the respiratory system, the inhalation phase : Compression and elastic eM | COSTI; Fig. 2 is the same, the expiration phase during expansion of the bubble. The respiratory system contains a closed pipeline connected to the gubniko M 2 and the "hand-knot", made in the form of a housing 3, in which an inlet 4 and an outlet 5, and a fitting 6 for connecting an elastic container 7. A constant gas source 8 is connected to the pipeline 1. The absorber 9 is designed to remove such pollutants as carbon dioxide from the respiratory tract. a return clanap 10. On the casing 3 an exhaust valve I and a movable element 12 are mounted, made, for example, in the form of bellows or blower bellows compressing and loosening, depending on the pressure change in the respiratory system. These movements of the movable element are transmitted to the valve plate 13 of the exhaust valve through a lever 14 having two arms 15 and 16 and a support 17. Arm 16 loading the lever 14 is made in the form of a thin plate, the area of which corresponds to the contacting surface of the moving element 12. Above the arm 15 is installed a magnet 18 attracting a metal plate 19 fixed on this lever arm. The valve assembly is also provided with a single-sided valve 20 located between the outlet valves I, on the one hand, and the elastic container and the movable element 12, on the other hand. The valve 20 is directed so as to prevent the gas from moving when the elastic container 7 is compressed towards the exhaust valve 11. It separates the cavity of the housing 3 in two separate chambers. Throttle device 21 with a hole 22 having a reduced flow area. intended to inhibit the propagation of pressure in the respiratory system, which may be caused by the compression of the elastic container 7. The manual deblocker 23 is designed to interfere with the control of the exhaust valve AND (as shown in Fig. 2) if it is blocked accidentally as a result of any malfunctions . The subject of the invention 1. A breathing system comprising a closed pipe connected to a mask or mouthpiece, a device for threading gas. an exhaust valve with a saddle and a closing element and a carbon dioxide absorber., characterized in that, in order to transfer the force to the closing element of the exhaust valve, depending on the existing pressure in the system and the valve opening, it is equipped with a movable The element, the power transmission device and the elastic tank located behind the outlet plug are relative to the direction of gas movement. 2. A system of claim 1, characterized in that, in order to move the gas withdrawn from the elastic tank along the entire pipeline to the exhaust valve, the ociiaiuen 0 closed circuit:. an element and an elastic capacity. 3. The system according to claim 1, wherein ni and so that, in order to delay the transfer of gas pressure in time from the bubble to the discharge valve, the closed pipe is connected to the pipe (m the patient and the outlet 1clan is equipped with a throttle device M in the form of a nozzle or 4. The system according to claim 1, characterized in that, with the aim of ensuring the operation of the system under the influence of the force generated by the expansion of the movable element, the valve assembly of the inlet and outlet ports and the fitting on which the elastic container is fixed with a balancing device, a coupling of a movable element and a lever. 5. The system of claim 1, characterized in that, in order to obtain such a magnitude of the magnet force of attraction, in which the excess pressure in the valve achorpus exceeds the loading edge, the shoulder The arms of the lever are equipped with a metal plate, above which a magnet located on the opposite side of the load arm is mounted. 6. The system of claim 1, in order to move the gas from one chamber through one valve to another, into which the openings of the elastic tank and the moving element are opened, the valve body is divided by a one-way valve separate cameras.
