Description

 The invention relates to medicine, namely to therapy, and can be used for diagnostic and therapeutic purposes, as well as for the prevention and training of respiratory and circulatory systems in stationary, outpatient and outpatient settings.

 Known breathing apparatus for creating hypoxia [1]. However, its design is inconvenient for use with active treatment in motion due to bulkiness and severity.

 Closest to the technical nature of the proposed device is a breathing apparatus for hypoxytherapy [2], containing a respiratory capacity formed by a rigid body and an elastic reservoir mounted on the flange of the body at its base, and communicated with the connection element to the patient through the supply pipe of the respiratory mixture, fixed on the side surface of the housing, an adjustable intake of atmospheric air with a spring-loaded valve, a nozzle for removing condensate installed in the housing cover, to apan supply valve and breathing gas exit filter.

However, the known device has the following disadvantages:
- long-term preparation of the device for the beginning of therapeutic respiration (refueling with an absorber, a large number of respiratory cycles to fill the reservoir);
- removal of excess CO _{2 is} carried out by absorbing it with an adsorbent, which, when saturated, becomes unsuitable for testing and requires control of the degree of saturation and suitability for further use, entering into a chemical reaction with carbon dioxide, increases the temperature in the absence of cooling;
- the inability to control the concentration of the hypoxic mixture in the inhaled air, control its composition;
- bulkiness, heavy weight suggest only stationary use.

 The aim of the invention is to control the concentration of the hypoxic mixture in the inhaled air, control its composition, reduce the size and weight of the device.

 This goal is achieved by the fact that in the breathing apparatus for creating hypoxia containing means for connecting to the patient, in communication with the body, at the entrance of which there is an adjustable intake of atmospheric air with a filter and a spring-loaded valve, and at the outlet a breathing tank, condensate collector is fixed, the body is made cylindrical the cavity of which is made in the form of a mixing chamber, additionally equipped with an inlet pipe, into the cavity of which an adjustable intake of atmospheric air, a filter and a valve, a mouthpiece for communication with a means for connecting to a patient, made in the form of a mouthpiece, a nipple and an adjustable throttle installed at the outlet of the body and made in the form of a removable plate with a number of through holes, and an additional nozzle and condensate collector are installed in the bottom of the respiratory capacity .

 The drawing shows the proposed apparatus.

 The apparatus comprises a housing 1 with a mixing chamber, an inlet pipe 2, an air intake 3, a filter 4, a valve 5, an adjustable throttle 6, a nipple 7, a mouthpiece 8, a mouthpiece 9, an elastic bag 10, a purge nozzle 11, a condensate collector 12, a spool washer 13 screw 14.

 The device operates as follows. The work is based on the reuse of outlet products with the addition of oxygen from the atmosphere. The nose is clamped with a nose clip. When exhaling, the products of exhalation through the mouthpiece 6, the open valve 5 and the opening of the adjustable throttle 6 fill the elastic bag 10. At the end of the exit, some of the exhaled products through the purge jet 11 and the openings in the condensate collector 12 go into the atmosphere.

 At the entrance, the products of exit from the breathing bag enter the entrance only through the openings of the adjustable throttle 6, the flow from the breathing bag is throttled, which ensures the suction of the necessary air from the atmosphere to obtain the desired composition of the hypoxic mixture.

 The device operates according to a one-valve scheme, which eliminates the need for a mask with hoses, and reduces the size and weight of the device.

 An example of a specific performance is given in the form of an extract from the examination protocol.

 Patient M., 26 years old. Clinical diagnosis: cardiac neurocirculatory dystonia. Complaints of frequent stitching pains in the heart area without irradiation after mental and physical exertion, a feeling of lack of air, fatigue, sweating. The duration of the disease is one year after mental stress. Functional tests (orthostatic, general hypoxic test, Letunov test) revealed various dystonic reactions of the cardiovascular system.

 In order to increase adaptation to hypoxia, the patient trained by breathing a hypoxic gas mixture containing 12% oxygen using a breathing apparatus for six sessions per week for 30 minutes for two weeks.

 As a result of training in response to an orthostatic test, the recovery period of pulse and blood pressure decreased. The reaction of the cardiovascular system to the Letunov combined test was characterized by a change in the dystonic reaction to the normotonic one. In response to a general hypoxic test, the hypertonic reaction of the cardiovascular system changed to normotonic. Complaints of a feeling of lack of air, increased fatigue disappeared, and pain in the heart became rare.

 Using training with moderate hypoxic hypoxia by inhaling a gas mixture with a low oxygen content using a breathing apparatus to create hypoxia causes the cardiovascular and respiratory systems to be trained for hypoxia and physical activity.
