The invention relates to medical equipment for use with curative purpose and non-pharmacological treatment of patients with pulmonary and other diseases.

A known method of treatment of bronchopulmonary diseases, based on creating resistance on the inhale and exhale using tool type “whistle”, “Flutter”, etc. the Principle of such devices is described on the example of the simulator breathing “Inga” in Gorbenko P.P. and other “Respiratory vibrator in the prevention and treatment of diseases of the respiratory system, the Almanac for General practitioners “Saint-Petersburg medical Gazette, 1993, No. 3, p.78...79.

The principle of operation of the respiratory vibrator is to create a positive oscillatory pressure at the outlet due to the beat frequency from 11 to 15 Hz) oscillations of the ball located at the exit of the duct, through which a certain amount of pressure the patient exhales. Oscillations positive pressure increase intrabronchial pressure that reaches the peripheral structures and provides bronchodilation effect. The result of treatment is to facilitate sputum discharge, reducing the severity of bronchial obstruction, improving the health of patients, reduction of medication therapy.

It is also known a device for the treatment of bronchopulmonary is of deseases in U.S. Pat. Germany No. 3624643. It consists of a split housing with slots for output exhaled by the patient air. The case contains a saddle and a metal ball. The housing is connected to the mouthpiece duct, through which the cavity of the body enters the air exhaled by the patient. During exhalation, the ball oscillates periodically blocking the hole in the saddle, which creates oscillations intrabronchial pressure and, therefore, has a massaging effect on the tissue of the pulmonary system.

However, this vibrator allows you to create only one physical factor, due to the mechanical effect intrabronchial vibrations positive pressure, which limits its therapeutic efficacy and spectrum of treatable diseases.

Practical application found trainer-inhaler Frolov in U.S. Pat. Of the Russian Federation No. 1170417. It is quite simple in construction and contains a total of 12 parts, but has a large size. Breathing simulator Pat. Of the Russian Federation No. 2165269 functionally similar to simulator-inhaler according to U.S. Pat. Of the Russian Federation No. 1170417, but structurally much more complex and contains 33 items. Simulators-inhalers in U.S. Pat. Of the Russian Federation No. 2140298 and No. 2124368 contain additional device that provides security when the device is used as an inhaler. The developed device is not to be used as ingest the RA, since the goal is to create simple, small, but effective design of the breathing simulator.

Also known respiratory simulator RF patent No. 2071360 (prototype), which consists of a mouthpiece-duct housing with a lid, ball and seat with a Central hole.

Tasks of invention - improving treatment effectiveness, broadening the spectrum of treatable diseases, simplifying the design of the simulator and a significant reduction in its size. In addition, the task of providing personalized trainer and regulatory regimes load.

These tasks are achieved due to the fact that in the breathing simulator, consisting of a mouthpiece-duct housing with a lid, ball and seat with a Central hole, forming a check valve, the check valve configured to close when you exhale, the body is made of the overflow drain, between the housing and the mouthpiece-duct installed perforated membrane to limit the stroke of the ball. The saddle can be performed inside, in the form of a conical recess and the center hole. The overflow drain should be carried out to control their area and to apply the means of adjustment of the overflow holes when you inhale. The means of adjustment re asknih holes when the breath is made in the form of a ring with overflow holes mounted on the case can be rotated. The bypass holes can be made with the possibility of regulation of their area, and must contain a means for regulating the area of the bypass channel during exhalation. The means of adjustment of the overflow holes when you exhale contains the lid with overflow holes, mounted on the housing can be rotated. The device may include means for regulating the area of the bypass channel when you inhale and exhale at the same time. Means to regulate the size of the bypass hole is made in the form of a ring and cover with radial holes, and the ring and cover is made with a possibility of rotation relative to the housing. The ball may be made of metal or plastic, and the perforated membrane is elastic or resilient, with the ability to preload the ball to the seat. The mouthpiece duct may be mounted coaxially with the housing, or at any angle, such as 90° or 145°. The means to regulate the size of the bypass holes may be made with the possibility of discrete regulation and fixing the position.

Studies have shown that the proposed solution has novelty, inventive step and industrial applicability, i.e. all criteria of the invention. Large-scale mass production of the device does not require the duty to regulate special technologies and materials.

In addition to the positive effect achieved when using the prototype, implemented therapeutic effect, which provides the Buteyko method and apparatus Frolov in U.S. Pat. Of the Russian Federation No. 1790417, namely the favourable impact of higher levels of carbon dioxide in the blood:

- cure bronchopulmonary diseases, for example bronchial asthma,

- treatment of a wide range of other diseases,

- pain,

- vasodilator action,

- decrease in blood pressure.

The Buteyko method (site Internet http.www.medlux.ru developed by Konstantin Pavlovich Buteyko is to create a high content of carbon dioxide in the pulmonary alveoli through breathing exercises without the use of hardware. The method consists in the control of breathing until a slight deficiency of air, or hard to speed up the treatment process. As a result, in the alveoli of the lungs increasing the content of carbon dioxide and how it does not seem paradoxical, improves the supply of oxygen to body tissues. This is because the oxygen is delivered to tissues not in the form of gas, and in connection with the hemoglobin of the blood. When the deficiency of carbon dioxide hemoglobin forms with oxygen stable connection and exchange of oxygen to the cells becomes impossible. This is especially dangerous for patients with BD who nhialdiu asthma.

The disadvantage of this method is that to get the effect you want to engage in this method long enough for 1...2 hours daily, which is laborious and requires a lot of willpower. In the Frolov device is implemented the same method but to get the effect enough to breathe using the Frolov device 10 min. the Frolov Device also has disadvantages: it is big in size, can not always be carried in pocket or taken with you when you leave home, for example, in the store or at the cottage, which is necessary, for example, patients with bronchial asthma.

The most significant structural difference of the invention from the prototype is that the check valve is installed in such a way that closes during exhalation, and in the prototype when you inhale it it provides a positive effect and simplifies the design, reduces the size of the device and makes it portable, for example, in a pocket.

The invention is illustrated in figure 1...16 where:

on Fig...16 - appearance of one of the variants of the device.

A breathing simulator (figure 1) contains a mouthpiece duct 1, building 2, located at the end of the mouthpiece of the pipe 1. The housing 2 may be collapsible. Inside the housing 2 or in concert with him made saddle 3 with a Central hole “A” and set the bulb 4. Between the housing 2 and the mouthpiece-the duct 1 is perforated membrane 5. In the housing 2 is made the bypass channels “B”, which reported an internal cavity “In” with the environment, to ensure a minimum flow rate of air during exhalation.

The second option (figure 2) with adjustable inspiratory further comprises a cover 6 with overflow (radial) holes “G”, mounted on the housing 2, which is also made of the overflow drain “D”. The cover 6 has limited rotation.

The third adjustable variant of the respiratory simulator (figure 3) contains the ring 7 with the suspended therein a by-pass holes “E”. In the housing 2 is made of the overflow drain “W”. Instead of holes “E” and “W” can be made grooves. The bypass holes “E” and “W” combined completely or partially. The ring 7 is made with the possibility of restricted rotation due to the groove “And”made in the cover 6 or the ring 7 and pin 8 mounted in the housing 2 (Fig and 9)restricts the rotation.

The fourth option (figure 4) contains both control options that are implemented by the cover 6 and the ring 7. Figure 5 and 7 shows a variant with perforated elastic membrane 5, which draws the ball 4 at the top (or left) position. There are various layout mouthpiece-duct 1 with the housing 2. The discrete device fixing cover 3 (6) may be performed, for example, by means of leaf spring 9. On Fig and 9 shows the section a-a, which shows the operation of the control device by-pass channels in two positions: when fully aligned holes “E” and “W” and maximally overlapped.

Figure 10 shows a layout of the mouthpiece of the pipe 1 and the housing at an angle of 90°and figure 11 is at an angle 145°. Figure 11 shows the device with the location of the axis of the mouthpiece-duct and housing - angle 145°. This location while running the ball 4 of the metal may be appropriate as to ensure Ecevit opening of the valve under its own weight bulb 4.

The position of the device details Fig - expiratory and inspiratory - to Fig, in the first case, the ball 4 is in its upper position, the second at the bottom.

The external appearance of one embodiment of the device shown in Fig...16, includes mouthpiece duct 1, building 2, cover 3 and the ring 7.

The device works in the following way (Fig and 13).

When inhaling the ball 3 opens the Central hole a and the air goes through it and the hole “E” and “W”having a smaller diameter than the Central hole. The result is a delay on the exhale to 20...30 sec. This creates a high content of carbon dioxide in the blood and thus in addition to positive effects on the lungs and bronchi creates a therapeutic effect similar to that create exercises by method Buteyko K.P. and when using the Frolov device on the Pat of the Russian Federation No. 1790417. Then perform the breath for 15 to 20 seconds and then slow breath. Ball 4 (Fig) opens the Central hole a and inhale through hole “D”, “D”, “E” and “W”. In the breath and exhale carbon dioxide in the lungs is increased in 2...3 times, which is sufficient to increase the content of carbon dioxide in the blood.

But unlike the Frolov device the design of the proposed respiratory simulator is much easier and less on ha is aritem. The Frolov device according to U.S. Pat. Of the Russian Federation No. 1790417 contains the capacity of large volume of 3 l, required for accumulation of carbon dioxide, the proposed method involves the accumulation of carbon dioxide in the lungs of the patient. The small size of the proposed unit creates another positive feature is the ease of operation, as when carrying out medical procedures, the patient can freely move and do some simple work, for example, to walk, to read, write, watch TV. By turning the cover 3 or the ring 7 (Fig and 9) provide individual adjustment of the process of inhalation and exhalation. Adjustment is necessary for individual settings of the simulator, for example, for men, women and children.
