Description

 The invention relates to medical equipment and can be used for the prevention and treatment of the respiratory system with a low oxygen content in the inhaled air saturated with salt vapors.

 Known breathing apparatus for creating hypoxia, containing a mask, valves and channels of inhalation and exhalation, a carbon dioxide absorber, a dust filter, a breathing tank, an atmospheric air intake and a housing with a cover (SU, 2087785 A1, IPC F 16 L 13/11, publ. BI 23.1997).

 This unit is not multifunctional because it lacks the possibility of saturating the inhaled air with a low oxygen content by salt vapor.

 The closest technical solution to the claimed is a breathing apparatus for creating hypoxia, containing a mask, valve box, inspiration and expiration channels, an absorption column (carbon dioxide absorber), a breathing reservoir in the form of an elastic volumetric container, a glass 21 with a salt chamber located inside it, under which has an air intake chamber 9, and with a regulator and inlets of different diameters (SU, 1674858 A1, IPC A 61 M 16/00, BI 33, 09/07/91) - a prototype.

 This design provides treatment and prophylaxis of the patient with oxygen-depleted air saturated with salt vapor, however, this design is rather cumbersome, structurally complex and, in addition, stationary.

 The objective of the invention is to improve the design of the apparatus.

 The technical result that will be achieved from the use of this invention is to create a compact, mobile and cheaper installation.

 The technical result is achieved by the fact that in a breathing apparatus for hypoxia containing a mask, valves and hoses of inhalation and exhalation, a carbon dioxide absorber, a breathing apparatus, a glass with a salt chamber located inside it, an air intake chamber with a regulator and air inlet openings, the glass is installed inside air intake chamber and is additionally equipped with a dehumidifier. Moreover, the carbon dioxide absorber, dehumidifier and salt chamber are installed in the glass in series and are separated from each other by breathable partitions. The air intake chamber is detachable. The inspiratory hose is connected to the air intake chamber and is equipped with a dust filter.

 To facilitate patient breathing, the inspiratory and expiratory valves are located in the mask.

 The essence of the proposed technical solution lies in the constructive solution of the apparatus, in another scheme for inhaling air saturated with salt vapor. This design, in contrast to the prototype, where the patient inhales air from the breathing apparatus, drawing it through a layer of salt (salt chamber), allows the patient to breathe directly already saturated with salt vapor air directly from the intake chamber.

 The location of the cup inside the detachable air intake chamber and the sequential placement of the carbon dioxide absorber, dehumidifier and salt chamber separated from each other by breathable baffles, as well as providing the inhalation hose with a dust filter and attaching it (hose) directly to the air intake chamber, makes it easier to access the inhaled mixture to the patient. Placing the inspiratory and expiratory valves in the mask makes it easier for the patient to breathe.

 This arrangement of the main sections of the apparatus allows you to create a compact, mobile and cheaper installation.

 From the analysis of scientific, technical and patent literature of the claimed combination of features is not revealed, which allows us to conclude that the claimed technical solution meets the criteria of "novelty" and "inventive step".

 The invention is illustrated in the drawing, which shows a General view of the breathing apparatus in section.

 The hypoxia breathing apparatus contains a mask 1, inhalation valves 2 and exhalation 3, inhalation hoses 4 and exhalation 5, a detachable air intake chamber 6 with a glass 7 located inside it. A breathing tank 8 is installed from the end of the air intake chamber. A carbon dioxide absorber is sequentially installed inside the glass. 9, a desiccant 10, and a salt chamber 11 (depending on operating conditions, the volume of sections: a carbon dioxide absorber, a desiccant, and a salt chamber may vary). All sections of the glass are separated by breathable partitions 13. At the end of the chamber 6 there are air inlets 14 and a regulator 15. The inhalation hose 4 is equipped with a dust filter 12 and is connected to the opposite part of the chamber 6.

 The invention is as follows.

 Before the start of the session, the patient inhales air from the atmosphere into the mask 1 with the inhalation valve 2 closed. Air through the exhalation valve 3, hose 5 enters the glass 7, where it passes successively through the air-permeable partition 13 into the carbon dioxide absorber 9, then through the next partition 13 into the desiccant 10, where the air gives off moisture, after which it is cleaned of carbon dioxide and dehydrated air through the next partition 13 enters the chamber 11, filled with coarse-grained salt. Here, the air is saturated with salt vapors and then through the next partition 13 enters the breathing tank 8.

 The patient needs to take several breaths from the atmosphere and several exhalations into the mask 1 to fill the entire volume of the respiratory reservoir 8. The air contained in this reservoir 8 contains approximately 17% oxygen (i.e., a reduced amount of oxygen compared to its content in atmospheric air) and aerosol NaCl (salt vapor).

 After filling the respiratory reservoir 8 with the treatment gas-air mixture, the patient proceeds to breathe through the mask 1 with the valve 2 open.

 The gas-air mixture from the breathing apparatus 8 through the air intake chamber 6 through the hose 4 through the dust filter 12 enters the mask 1 and through it to the patient. Then the patient through the valve 4 exhales air, which then goes through the hose 5 all the way described above.

 With each act of inhalation-expiration, the oxygen content in the inhaled gas-air mixture decreases (the amount of NaCl aerosol is constant), i.e. hypoxia is created. Thus, the effect of simultaneous exposure of the patient to hypoxia and aerosol therapy is created. The intake of outside atmospheric air (suction) in the air intake chamber 8 is carried out through the holes 14 and is regulated by the regulator 15 (the holes with the regulator can be of different diameters).

 The patient inhales such a mixture until he feels difficulty breathing. He must end the session. For some time the patient breathes normal atmospheric air, then the session can be repeated.

 Such a device is compact, convenient to use (portable), and it allows treating patients both in stationary conditions of polyclinics, hospitals, dispensaries and other medical institutions, as well as at home.
