Description

The utility model relates to the field of medicine, namely to pulmonological physiotherapeutic devices, and can be used for breathing treatment and prophylactic mixtures under excessive pressure in children suffering from bronchopulmonary pathology.

A device for breathing, containing an oxygen source, a housing, an inspiratory-expiration valve and a control unit (1).

The disadvantage of this device is the design complexity and lack of effectiveness of the therapeutic effect.

A device is known comprising a mouthpiece, a housing, an inspiratory-expiratory valve and an adjustable expiratory resistance (2).

The disadvantage of this device is the low effectiveness of the therapeutic effect.

Known breathing apparatus containing a housing, an inspiratory-expiration valve, respiratory channels and a locking element (3).

The disadvantage of this device is the inconvenience of use.

A device for breathing is known, comprising a body, a mouthpiece and an inspiratory-expiratory valve (4).

The disadvantage of this device is the low effectiveness of the therapeutic effect.

A device for breathing apparatus is known, comprising a housing, a mouthpiece, an inspiratory-expiratory valve, and a gas inlet and outlet fitting (5).

The disadvantage of this device is the high cost of the treatment process due to unproductive consumption of the respiratory mixture.

A known breathing apparatus valve comprising a three-way housing, a gas inlet and outlet fitting, an inspiratory-expiratory valve and an elastic membrane (6).

The disadvantage of this valve is the low effectiveness of the treatment effect, as well as the high cost of the treatment process due to unproductive consumption of the respiratory mixture, which, however, is a common disadvantage of most known respiratory devices, since the respiratory mixture is consumed by such devices constantly, both during inspiration and during exhalation. Meanwhile, in devices such as, for example, a “nebulizer”, expensive and often scarce drugs are used to prepare the respiratory mixture.

The purpose of creating a utility model is to increase the efficiency of use of the device, by stopping the flow of the respiratory mixture during exhalation.

This goal is achieved by the fact that the device body is made with a mouthpiece at the distal end and with an opening at the proximal end, the inspiratory-expiration valve is made in the form of a hollow cylinder plugged at the proximal end with an opening on the cylindrical wall, fixed in the initial position from the distal and proximal ends by springs , on the side wall of the body there is an opening of the pipe for supplying the respiratory mixture and an exhalation hole, which is alternately aligned during breathing with the hole in the wall of the inspiratory-expiratory valve, and troystvo may be made of a biologically and chemically inert polymer and of translucent material, the shell has a range of breath parameters, and the pointer scale deposited on the wall of the inhalation-exhalation valve.

Comparison of the proposed device with other known in the field of medicine devices for breathing under excessive pressure showed its compliance with the criteria of the utility model.

The utility model is illustrated by graphic material. Figure 1 shows the appearance of the proposed device in the expanded state;

figure 2 shows a section of the device in its original state; figure 3 and figure 4 shows the same section of the device at the time of inhalation and exhalation, respectively;

figure 5 shows an embodiment of a device with a scale of respiration parameters applied to the housing.

The device for breathing under excessive pressure comprises a cylindrical body 1 with a mouthpiece 2 at the distal end and an opening 3 at the proximal end, an inlet 4 of the pipe 5 for supplying the respiratory mixture and an outlet 6 for exhalation. In the housing 1 there is an inspiratory-expiratory valve made in the form of a hollow cylinder 7, with a muffled proximal end face 8 and with an opening 9 on the cylindrical wall. In the initial position, the inspiratory-expiratory valve is fixed from the distal end by the spring 10, and from the proximal end by the spring 11. The device can be made of biologically and chemically inert material, which will allow for its antiseptic treatment and repeated use. The device can be made of translucent, for example, polymeric material with a scale of 12 respiration parameters on the cylindrical wall of the housing 1 and with an arrow - pointer 13 on the inspiratory-expiratory valve 7.

A device for breathing under excessive pressure is used in children as follows. The pipe 5 is used as a handle. Connect the pipe 5 to the source of the respiratory mixture, for example, a nebulizer or an oxygen concentrator. In the initial state, the inspiratory-expiratory valve 7 is in the middle position shown in FIG. 2. When inhaling inside the housing 1 creates a vacuum, under the action

which valve 7 inhalation-exhalation, overcoming the resistance of the spring 10, moves to the distal part of the housing 1, in the direction of the mouthpiece 1 (see Figure 3). In this case, the opening 9 of the valve 7 of the inhalation-exhalation is combined with the opening 4 of the nozzle 5 of the supply of the respiratory mixture, and the breathing mixture through the hole 4 of the nozzle 5, the hole 9 of the valve 7 of the inhalation-exhalation, the mouthpiece 2 enters the lungs of the child. At the time of the end of inspiration, the valve 7 of the inspiration-expiration under the action of the spring 10 returns to its original, middle position (see Figure 2) and the flow of the respiratory mixture is stopped. When exhaling in the housing 1 of the device creates excessive pressure, under the influence of which the valve 7 inhalation-exhalation deviates to the proximal part of the housing 1, overcoming the resistance of the spring 11 (see Figure 4). In this case, the opening 9 of the valve 7 of the inhalation-exhalation is combined with the opening 6 of the exhalation of the body 1, and the spent breathing mixture from the lungs of the sick child through the mouthpiece 2, the hole 9 of the valve 7 of the inhalation-exhalation, the hole 6 of the housing 1 is discharged into the environment. At the end of the exhalation, the inspiratory-expiration valve 7 under the action of the spring 11 returns to its initial, middle position (see Figure 2).

Thus, the device consumes the respiratory mixture only when the child is inhaling, since the rest of the time, the opening 4 of the pipe 5 for supplying the respiratory mixture is blocked by the cylindrical wall of the inspiration-expiration valve 7.

For better glide valve 7 inhalation-exhalation and, therefore, more reliable operation of the device on the inner surface of the housing 1 can be applied lubricant, for example, petroleum jelly.

The described economy when using the device allows to halve the consumption of the respiratory mixture, which is very important, since expensive and scarce medicines (berodual, berotek, etc.) are often used to prepare the respiratory mixture. Or double the effectiveness of the treatment procedure, as the whole

the incoming breathing mixture completely (!) passes through the baby’s lungs.

The device for breathing under excess pressure is intended for sharing with respiratory mixture formation devices, for example, a nebulizer, an oxygen concentrator, etc.

The device is advisable to use in children in the treatment of bronchopulmonary diseases, both in a hospital and at home.
