The invention relates to the field of health and can be used for training the breathing mode of moderate hypoxia and hypercapnia with adjustable resistance to inhalation and exhalation.

Breathing simulator is designed for biological simulation of respiratory loads similar to those that occur during execution Wellness exercise: running, swimming, gymnastics, skiing, etc.

The main training components of the respiratory system are:

- short active breath, ending with a short pause;

- uniform, continuous, but with effort, exhale;

- the presence of moderate impoverished oxygen in the breathing mixture (hypoxia) with a high content of carbon dioxide (hypercapnia).

Wide and, in General, very successful practice in recent years on the application of known respiratory simulators allows reasonably determined by the rational limits of the value of the respiratory activity and their biological simulation. In particular, physiologically komfortnim is the resistance in the loop "inhale-exhale" about 25-35 mm Vogt Valid training load is the load from the upper limit of 150-200 mm Vogt Necessary and sufficient level of rational load, providing good training effect feature : the : resistance cycle "inhale-exhale" about 35-100 mm Vogt (see, for example, RU 98100020, EN 2129885).

These limits are the technical parameters of the best-known respiratory equipment, and also claimed the simulator.

Coaching action of the simulator is created by two factors: the formation in the mixing chamber moderately elevated concentrations of carbon dioxide in combination with low oxygen content and the creation of the measured resistance to inhalation and exhalation.

Training for proper use of respiratory equipment causes certain difficulties, especially in children.

The famous "Breathing simulator SCI Frolov (patent RU 2129885 C1, A 61 M 16/00, 27.10.99)containing a coaxially arranged inner and outer mixing chamber and a breathing tube connected to the intended upper part of the inner chamber. At the bottom of the outer chamber with the inner side is made open radial channels, which together with the lower end of the inner chamber to form openings for the passage of air. The lower portion of the annular gap between the chambers filled with water, providing resistance to inhalation and exhalation.

For reasons that impede the achievement of specified following technical result of using a known respiratory simulator, is the need for its permanent installation and operational complexity, especially at the beginning of training.

From the local inhaler-training device (patent RU 21440298 C1, A 61 M 16/00, 27.10.99)containing vessel with liquid, coaxially with a gap installed inside the mixing chamber with a perforated bottom and a breathing tube. The liquid in the vessel provides a resistance to inhalation and exhalation.

For reasons that impede the achievement of specified following technical result of using a known respiratory simulator, is the necessity of its stationary and upright, installation and operational complexity, especially at the beginning of training.

Known respiratory simulator (patent RU 2124369 C1, A 61 M 16/00, 10.01.99)containing the breathing tube of elastic material with two plots distal and proximal, provided at its ends respectively by screen-reflector and the mouthpiece. On the side of the breathing tube with holes in the form of cuts to create resistance on the inhale and the exhale. The trainer is supplied with a loop of flexible material to hold it on the neck of the user.

For reasons that impede the achievement of specified following technical result of using a known respiratory simulator, is the inability to create a moderate hypoxia and hypercapnia and the inability to adjust the resistance to inhalation and exhalation.

Known for being a breathing simulator "Inhaler, Frollo is a (patent SU 1790417 A3, A 61 M 15/02, 23.01.93), which essential features is the closest analogue of the claimed breathing simulator.

The known device comprises an outer mixing chamber, inside of which is located with a clearance relative to the walls and bottom of the internal mixing chamber, made in the form of a cylindrical closed vessel with perforated holes on the peripheral areas of the bottom, submerged in the liquid, particular object sticking its bloated in the outer chamber. In the lid of the outer chamber made a hole in which a gap is established breathing tube connected to a narrowed upper portion of the interior of the mixing chamber. The hole for breathing tube in the lid of the outer chamber is an opening for the movement of air during inhalation and exhalation.

In the mixing chambers of the correction is the chemical composition of the inhaled air mixture by mixing the ambient air and the air exhaled in the previous cycle, with increased content of carbon dioxide and reduced oxygen levels. The fluid in the outer chamber, creates increased resistance to inhalation and exhalation.

For reasons that impede the achievement of specified following technical result of using a known respiratory simulator, is the need for its permanent installation and clonos the operation, especially at the beginning of training.

The task, which is aimed by the invention is the development of the respiratory simulator with great ease of use and for monitoring the correct performance of the elements of the respiratory cycle.

Technical result achieved in the implementation of the claimed invention is the removal of restrictions in orientation and fixing the position of the exerciser during use, as well as providing opportunities indication of the quality elements of the respiratory cycle.

This technical result in the implementation of the invention is achieved by the fact that in the inventive breathing exerciser, comprising a cylindrical mixing chamber with a narrowed upper part connected with her breathing tube and the bottom with perforations on the peripheral area, in contrast to the well-known trainer, the bottom of the camera is made double, and in its internal cavity is placed a ring-shaped filter made of porous material of a given density, and the Central part of the bottom provided with communicating with the atmosphere and placed in a cell channel indicator breath, made in the form of a movable piston element, while the breathing tube is equipped with a sound indicator of the uniformity of exhalation, made in the form of resonantcavity unilateral action.

This technical result in the implementation of the invention is also achieved by the fact that the inner cavity of the bottom is provided with an additional removable load liners, made in the form of film disks with holes of a given area, as well as the fact that the trainer is supplied attached to the upper part of the chamber is adjustable along the length of the loop of flexible material.

In the inventive breathing simulator cylindrical mixing chamber 1 has a narrowed upper part 2, which is attached breathing tube 3, and a removable bottom 4 in the form of two mating cups 5 and 6 with perforations 7 and 8 on the peripheral parts of their ends. To the Central part of the bottom 4 have attached inside the chamber 1, the pipe 9, at the end of the channel 10 which is plugged in the form of a movable piston element 11, which is an indicator of breath. In the cavity 12 between the ends of the cups 5 and 6 posted by annular filter 13 of porous material of a given density and can be placed film disk 14 with holes 15. At the end of the breathing tube 3 has a resonant whistle 16 unilateral actions (e.g., Hartmann whistle). To the intended part 2 of the camera 1 is attached loop 17 in the form of a cord whose ends are sealed by the stopper 18.

Declare a breathing simulator works as follows.

The user, by inhalation through the respiratory tube 3, creates a negative air pressure in the chamber 1, the set value of which is recorded by the indicator of the breath - raising and hang in the upper position of the piston element 11, emits a sound signal (click). When you exhale resonant whistle 16 under the action of passing through it a certain air flow begins to emit a whistle, presence and not changing the tone which indicates the uniformity of the exhalation. On the next breath in the mixing chamber 1 is the correction of the chemical composition of the inhaled air mixture by mixing the ambient air and the air exhaled in the previous cycle, thus in the gas mixture increases the carbon dioxide content and is a moderate decrease in oxygen content. Set the resistance to inhalation and exhalation provides a filter 13 and a removable film disks 14 with different holes 15.

Attached to the exerciser adjustable along the length of the loop 17 allows you to secure the equipment on the neck of the user, providing the opportunity to use the simulator in motion.

The values of the parameters of the respiratory cycle can be set:

for breath - mass of the piston element 11;

- exhale - frequency audible what about the signal, published by microswitches 16;

- for the composition of the inhaled mixture with the volume of the mixing chamber.

Thus, it is seen, the above data confirm the possibility of implementing the claimed invention, the achievement of the technical result and solve the problem.
