The present invention relates to the field of medicine and can be used for prevention of various diseases, in the complex rehabilitation after myocardial infarction, bronchial asthma attacks, allergic reactions, and also to increase the overall resistance of the organism and other

It is now known that moderate concentrations of carbon dioxide can cause in humans a number of positive effects: improvement of blood circulation in the heart muscle, improving bronchial obstruction, normalization of the gastrointestinal tract, reducing the intensity of allergic reactions, increase endurance to hypoxia and exercise, improving the quality of life (Ann, Ofeleven, Unisystem. Eliminate the root cause of disease!/Under the editorship of Professor Ana.-Samara.: Paracelsus, 1998.-62 C.).

In this regard, the development of technical devices is an important task of medicine.

A device (Muvara, Acctuane, Internal with co-workers. Improving the efficiency of interval normobaric gipoksiterapiya addition to a hypoxic mixture of carbon dioxide /In kN.: Intermittent normobaric hypoxic therapy. Reports of the Academy of problems gipoksiei of the Russian Federation. TSM: AIMS, 1999.-c.89-91), in which with the help of the generators and membranes create different concentration of carbon dioxide in the inhaled mixture. However, the used devices are bulky, stationary and expensive. The latter does not allow for accessibility to the device of the broad masses of the population.

For the prototype, we made the device - hypercapnia design Y.N. Mishustin (RF Patent No. 2118542 “Trainer breathing individual”) - TDI-02 for individual use.

Trainer TDI-02 consists of two cylindrical included in one another and fill with water cameras directly connected to the breathing tube and mouthpiece. The inner chamber has a slit nozzle orifice to regulate the physical strain on the body. The whole structure is placed in the outer chamber of variable volume (glass jars of different capacities). The external camera is necessary to increase the concentration of carbon dioxide and decrease concentration of oxygen in the inhaled air mixture.

According to the instructions provided methods of using the device consists of several stages.

The first stage. Breath with minimal exertion. When assembling TDI-02 before each lesson, the water in the glass is not filled. The aperture set on the top of the glass. The top of the outer chamber is lowered to the limit.

If at the first training is unable without undue effort and discomfort to breathe through TDI-02 20 minutes, should be limited to Ensim time. Constantly from lesson to lesson time will spontaneously increase (up to 10 minutes).

When assembling the inner chamber by turning the nozzle it cracks are opposite the slots in the housing, so that all the cracks were discovered.

The second phase. When assembling TDI-02 before each class in a glass pour 2 tablespoons of warm boiled water. All slit nozzles are open (as in step 1). The aperture set at mid-height of the glass. The top of the outer chamber is lowered to the limit.

The third stage. When assembling TDI-02 before each class in a glass pour 3 tablespoons of water. All slit nozzles are open (as in step 1). Aperture is removed from the design. The top of the outer chamber is lowered to the limit.

The fourth stage is the final. When assembling TDI-02 before each class in a glass pour 3 tablespoons of water. Aperture is removed from the design. The upper part of the external camera raised to 60 mm from the bottom position.

During the fourth stage, it is recommended to gradually increase physical activity. To do this, in the collection of the internal chamber by turning the nozzle block the first one, then two, and at the end of phase three of the five slots of the nozzle.

The design of the device assumes the presence of exchangeable containers (glass jars of different capacities), filled with water. The device has up to 10 times the ornago details. However, when it revealed a number of drawbacks:

1. The size of the device is large enough that it requires installation, usually on a table or stand.

2. The device does not allow you to smoothly change the volume capacity for the accumulation of carbon dioxide. To change the amount of capacitance it is necessary to have a whole Arsenal of glass jars of different sizes.

3. The device has a sufficiently large number of details, which hinders their processing.

4. The device weighs up to 700 g, which limits its use in travel, business trips, leisure, sport and so on

5. The device is the separation of the air flow coming from the atmosphere and out of the device;

6. The device is able to monitor the process of intake air and condensate.

7. The device does not allow you to create a resistance to exhalation that would provide additional positive physiological effects.

8. The use of the instrument “normal” consumer is difficult because of the need to execute multiple instructions (pouring of water, the regulation of the diaphragm, replacement of external capacity, and others).

9. The cost of the device is relatively high.

The objectives of the present invention includes:

1. The creation of compact, lightweight and easy to handle the mouth of the STS, does not require additional parts to make it work.

2. Development of the device with continuously variable volume capacity for accumulation of carbon dioxide.

3. A device with a minimum number of easily machined parts.

4. The software in the device capabilities of the separation of the air flow entering from the atmosphere and emitted from the device.

5. Providing opportunities to make fences of air and condensate from the device.

6. The provision of technical capabilities in the device to create the resistance of the gas stream on the exhale.

7. Reducing the cost of the device in comparison with existing analogues.

The technical essence of the invention lies in the fact that the device for creating hypercapnia in humans chamber for the accumulation of carbon dioxide is made in the form of cylinders with conical bases located within one another and having a smooth move one relative to another, at one vertex of the outer cylinder is breathing tube with a mouthpiece at the other top - non-reversing valve with a flap made with the possibility of rotation with the aim of creating a resistance to exhalation, on the cylindrical surface of the outer cylinder installed capacity for the collection of condensate, and the tapered base of the distal part of the external qi is Indra placed the pipe for air sampling.

The technical result of the proposed device is receiving inhaled gas mixture with a high content of carbon dioxide, by switching the phases of inhalation and exhalation, and creating resistance to the breath on the exhale.

For explanation of figure 1 shows the General scheme of the device, and figure 2 - the direction of the air flow during exhalation.

The device consists of a chamber for the accumulation of carbon dioxide, consisting of two cylinders (cameras) (figure 1 and 1A), which are included in one another, respiratory Petrovka (2) with a mouthpiece (3), non-reversing valve (4) from valve (5), condensate collector (6) and nozzle for air sampling (7). Cylinders, moving one another, can gradually reduce the amount of space with 1200 ml to 500 ml cylinders marks corresponding to the volume of 1200 ml, 1000 ml and 500 ml

The device operates as follows. Cylinders 1 and 1A are bred in opposite directions, which corresponds to the maximum volume (1.2 l) “dead” space camera. The patient inserts the mouthpiece 3 in the mouth and puts the clamp on the nose. When performing the inhalation through the respiratory tube 2 (Fig 1) air flow through a separate entrance non-reversing valve (4) fills the cylinders and then enters into the lungs of the patient. In the implementation of exhalation (figure 2) exhaled air fills the cylinder and exits through the valve exhalation into the atmosphere. Can the use for these purposes, the valve company “AMB” - The AMB E1. Thus, when the exhalation portion of the exhaled gas with a high content of carbon dioxide lingers in the camera device, and each subsequent exhalation increases the concentration of carbon dioxide in the camera device. For convenience, the cylinder device marks, reflecting the volume of the chamber in this position the cylinder in the range from 1.2 to 0.5 liters. The volume change is a gradual movement of the cylinders relative to each other (the position shown in figa stroke). The condensate flows into the collector 6.

To create resistance on the exhale you on the exhalation valve to rotate the valve until it stops. Narrowing of the opening of the channel exhalation creates resistance of about 3-4 cm of water. Art. in normal deformiruemoi breath in adults. This mode is usually enabled after patient adaptation to high concentrations of carbon dioxide.

Measurements of carbon dioxide content in the cells of the device at 20-minute session respiration showed the results presented in the table.

The concentration of carbon dioxide in the chamber after a 20 minute session of breath
The chamber volume, mlThe concentration of CO2, %
MinimalMaximum
12002,23,1
10001,82,6
5001,02,0

As the table shows, the use of the proposed device allows to achieve different concentrations of carbon, ranging from 1.0% to 3.1% in the inhaled gas environment. The opportunity gradually to change their volume and, accordingly, the concentration of CO2in the inhaled gas mixture allows the use of the device of the patients (sick and healthy) with different adaptive capabilities.

Thus, the proposed device has a number of advantages over known:

1. The device allows metered continuously vary the chamber volume without additional hardware.

2. The device is very compact and weighs only 200g

3. The device comprises a minimum number of parts, allowing to obtain additional physiological effect (resistance to exhalation).

4. The device allows you to split the incoming and outgoing air flow from the respiratory tract.

5. The device allows for fences of air and condensate that has value when control creation of hypercapnia and the human condition.

6. The device allows along with the creation of elevated concentrations of carbon dioxide in the inhaled gas mixture in order to accumulate resistance to exhalation.

7. The device is easy to handle.

8. The presence of a simple device components made of inexpensive material, greatly reduces its value.

Medico-social effect of the proposed device is the possibility of its wide use in various populations of patients during illness and rehabilitation, as well as in healthy patients, athletes to prevent disease and improve your endurance (increased resistance) to a variety of adverse effects and to improve the quality of life.

Easy operation of the device, its low cost is a prerequisite for mass implementation of the device in the General population.
