Description

The invention relates to medicine and, in particular, to salt inhalers used for the treatment and prevention of diseases associated with pathology of the respiratory tract. The haloengulator can be used in various fields of medicine (pulmonology, allergology, pediatrics, otorhinolaryngology). The haloengulator can be used for the treatment and prevention of acute respiratory diseases, tonsillitis, pharyngitis, laryngitis, bronchitis, bronchial asthma, chronic obstructive pulmonary disease. Regular use of the haloengulator helps to restore the protective functions of the body. The use of a haloing agent for preventive procedures by smokers and people with exogenous risk factors allows you to eliminate the initial manifestations of obstruction and restore the protective function of the respiratory tract.

The healing properties of sea air and sea water, air of salt caves are indisputable. Inhalation of air saturated with sea salt or salt of salt caves helps to cleanse the respiratory tract and restore the vital functions of the body. In particular, inhalation of air saturated with salt helps to reduce the effects of pollen allergy and other respiratory tract allergies, reduce symptoms of asthma, bronchitis, infectious diseases of the respiratory tract, and reduce respiratory problems caused by smoking. Breathing with salt-saturated air is economically and efficiently ensured by the use of salt inhalers, which are also called halo-inhalers, that create the conditions for breathing with a salt aerosol mixture. Halo-inhalers provide the user with a salt aerosol mixture similar in properties to sea air or salt cave air. According to medical statistics, such halotherapy improves the health status of patients suffering from diseases of the respiratory system by 90%.

Halo means salt, halotherapy is a therapy in which the usual salt (NaCl) is used predominantly for the treatment and prevention of diseases. Haloengulator - salt inhaler. However, it is preferable to use sea salt or salt from salt caves of pharmacopoeial quality. Such a salt, in addition to NaCl, includes many trace elements.

A dry powder inhaler is known from US Pat. No. 6,151,130, which salt can be used containing a space for accommodating a container containing dry powder, a vibrating element, a flow channel, an electronic circuit for electrically actuating the vibrating element, said container having a flat bottom the wall, the upper wall and the side wall, there is at least one hole for the release of the drug substance on the upper wall of the container, and the vibration element has a plane a surface configured to couple to the flat bottom of the container to allow the container to vibrate and to eject said drug substance from the container through at least one opening for ejecting the drug substance into the patient's breathing passage. The known inhaler is complicated, expensive, the salt concentration in the aerosol is low, it does not create conditions corresponding to the real conditions of salt caves or the sea coast, long-term sessions are required to obtain a therapeutic effect.

Famous industrial inhaler Salitair, manufactured by Medi Direct, England. This inhaler creates a microclimate of a salt cave by inhalation and is a dry-type reusable inhaler that can be opened, washed and cleaned; the replaceable salt is supplied. This inhaler, however, is not cheap, the aerosol mixture created has a low salt content, so the therapeutic effect is insufficient, the sessions are long.

The halo-inhaler according to Belarus patent BY 8330 is a device containing a housing, an axial air duct with a salt-saturated chamber, the walls of which are made of sodium and potassium salts. The salt saturation chamber is made in the form of a hollow truncated cone or cylinder, the lower part of the chamber contains openings for air intake, the bottom of the chamber is rigidly fixed to a stand made of insulating material, an electric bulb with voltage from 12 to 220 V is installed vertically in the center of the bottom, in the middle part of the inner a volume of the chamber, a device for purifying air using an electric ionic wind is installed, containing a corona electrode, a target electrode, a constant voltage element and holding Tel, and the bottom portion of the chamber from the outside is mounted bactericidal filter to clean air entering the chamber. The haloengulator is complex, heavy, expensive, uncomfortable.

The halogenator according to the patent for a utility model of Russia RU 31961 contains a housing and an aerosol generator located therein. The body is made in the form of a monolith of rock salt with an internal cavity and through channels in the walls of the monolith, and a quantum energy element is used as an aerosol generator. The inhaler is complex, does not provide a sufficient concentration of salt in the inhaled air, and requires quite lengthy procedures.

The closest analogue to the halo-inhaler disclosed here is a salt aerosol formation device according to RU patent No. 2027447, comprising a housing with an internal cavity for accommodating crushed salt rock, located on the side of its opposite ends of the outlet and inlet fittings, an air duct connected to the fan, an air heater and pressure regulator, characterized in that it is provided with a connecting element for the patient, the housing is mounted to rotate around a horizontal axis of symmetry and in in the middle part of the body there is a horizontal partition dividing its internal cavity into two communicating chambers, each of which is made with the possibility of changing its volume and contains an additional perforated jumper, while the fittings are made with the possibility of alternating interaction with the air duct and the connecting element, and through openings for oncoming flow. However, this inhaler also has a complex structure, does not provide a high salt concentration in the inhaled air mixture, is not economical, it requires long sessions of 15-20 minutes to achieve the desired healing effect.

Thus, the problem of providing a cheap simple, light, convenient, not requiring long sessions and at the same time ensuring the maintenance of a high concentration of salt in the inhaled air mixture of the inhaler, providing additional consumer benefits, remains unresolved.

The technical result achieved by using the claimed invention is to reduce the duration of breathing sessions, increase efficiency by reducing salt consumption and its full use during the life of the halo-inhaler, as well as maintaining a high salt concentration in the inhaled air mixture.

An additional technical result consists in improving the usability, ensuring reliability and performance throughout the life of the halogenator.

The technical result is achieved due to the fact that in the halo inhaler, which includes a housing with an internal cavity, an air duct for supplying air and a mouthpiece for supplying a salt aerosol to the user, an electric motor, a mixer, a power source, an electric motor power button, a latch connected to it and a protective cap for protecting the button when the electric motor is turned off, the housing is equipped with a sealed compartment for placing a power source for powering the electric motor when you press the power button and the camera for silica gel, covered by a filter pad and connected by means of lateral air channels with the atmosphere, the mixer is made in the form of a bowl into which pharmacopeia salt is poured, and mounted rotatably from an electric motor to mix and grind the pharmacopeia salt, the mouthpiece is removably mounted on the body and connected to the air duct, while between the mouthpiece and the air duct there are air channels for supplying a salt aerosol, connecting the internal cavity of the body with the mouthpiece, and the valve is installed it is possible to shut off inoperative the air channels for supplying a salt aerosol connecting the internal cavity of the body with the air duct and the mouthpiece, and opening these channels and blocking the channels connecting the silica gel chamber with the salt chamber in the working state with the button pressed.

An additional technical result is provided by the execution of the body, the mouthpiece and the protective cap of polyurethane plastic.

An additional technical result is also provided by the fact that the filter pad is made in the form of air-passing fine mesh.

An additional technical result is also ensured by the fact that the pharmacopoeial salt is poured into a conical bowl in an amount of 0.5 to 2 g, preferably in an amount of 1.0 g.

Known devices do not allow to provide these advantages in one device and at the same time.

The differences between the claimed halo-inhaler and portable multi-dose powder inhalers used in the treatment of diseases of the upper respiratory tract are that an electric motor, a mixer and a battery are used to create the aerosol mixture.

Unlike existing compressor and ultrasonic inhalers (nebulizers), where solutions of water or oil are always used, dry salt is poured into the halo inhaler and dry mixing and crushing (micronization) of the salt takes place.

The claimed haloengulator differs from existing halo-inhalers in portability, autonomy, and the use of pharmacopoeial salt (non-food grade).

The main feature of the claimed haloengulator is that as a result of the proposed scheme of mixing and crushing of salt, 70-97% of salt particles on inspiration are particles of the respiratory fraction (0.5-5 microns). This optimal particle size increases the efficiency of the procedure and, unlike existing halo-inhalers and halochambers, where the duration of one session is 10-40 minutes, it reduces one session to 2 minutes and the amount of inhaled salt to 5-7 mg / session.

A small amount of salt per session allows you to create a light (50 g), portable and stand-alone device that allows 30 sessions of 2 minutes, a course of 15 or 30 days.

This type of haloengulator is disposable, therefore salt replacement in the chamber or batteries is not provided, salt and battery charge are used almost completely, the used haloengulator must be disposed of.

The claimed haloengulator differs from the closest analogue in the following:

- an electric motor, a mixer, an electric power element, an electric motor power button, an associated valve and a protective cap for protecting the electric motor power button inoperative are introduced,

- the housing is equipped with a sealed compartment for placing a battery for powering the electric motor when you press the power button and a camera for placing silica gel connected by channels to the salt chamber,

- the cavity of the chamber for silica gel is blocked by a filter pad and is connected with the atmosphere using lateral air channels made in the mouthpiece body,

- the mixer is made in the form of a bowl in which the pharmacopeia salt is poured, and is mounted with the possibility of rotation from an electric motor for mixing and grinding the pharmacopeia salt,

- the mouthpiece is removable mounted on the housing and connected to the duct,

- the button is connected to a valve installed with the possibility of shutting down inoperative air channels for supplying a salt aerosol connecting the internal cavity of the body with the mouthpiece, and opening these channels and closing the channels connecting the silica gel chamber with the salt chamber, in working condition,

- pharmacopeia salt is poured into a conical bowl in an amount of 0.5-2 g, the halo-inhaler is a single-use inhaler,

- the case, the mouthpiece and the protective cap are made of polyurethane plastic,

- the filter pad is made in the form of air-passing fine mesh,

- pharmacopoeial salt is poured into a conical bowl in an amount of 0.5-2 g, preferably in an amount of 1.0 g

It is a convenient and inexpensive device with a modern design, optimally suited for home use.

The haloengulator is a device for converting pharmacopoeial salt into a finely divided salt suspension, which is carried out using an electric motor 8 with a mixer 7, which stir the salt and produce a salt suspension. In the haloinhalator, the salt suspension exits upward through the narrow air channels 15 of the air duct 2 and then through the mouthpiece 3 enters the respiratory tract of a person.

Salt suspension is the smallest particles of salt suspended in the air. Suspensions are subdivided by the size of the particles into high, medium and low dispersion. The smaller the aerosol particles, the longer they remain in the stream of inhaled air and the deeper they penetrate the respiratory tract.

Polyurethane plastic is used for the manufacture of the main parts of the halo-inhaler — the case, the mouthpiece, the protective cap.

The haloengulator comprises a vertical housing 1 divided into two compartments. The first compartment is a salt chamber 6 for placing salt and obtaining an aerosol mixture. A duct 2 and a mouthpiece 3 are connected with the chamber 6 through the air channels 15 for supplying the finished salt aerosol mixture to the user. The mouthpiece 3 is mounted vertically and coaxially with the housing 1. The mouthpiece 3 is removably fixed to the housing 1, which makes it possible to conveniently store the haloengulator and also to wash the mouthpiece after use. In the chamber 6 there is an electric motor 8 and a mixer 7. In the second sealed compartment 12 of the housing 1 there is an electric power element 5, which is a standard 1.5 V battery that powers the electric motor 8 when the button is pressed 9. The housing 1 is equipped with a lower cover 11 that covers the housing 1 haloing below. An electric motor switch button 9 is installed in the upper part of the housing 1 and connected to a valve 17, in which openings 20 are made for connecting the silica gel chamber 18 to the salt chamber 6 and an opening 21 connecting the air channels 15 for supplying the salt aerosol to the air duct 2 and the mouthpiece 3. When the button 9 is pressed, the electric motor 8 is energized and the channels 15 for feeding the salt aerosol through the hole 21 are connected to the air duct 2 and the mouthpiece 3.

Mixer 7 is a conical bowl in which pharmacopeia salt is poured in an amount of 1.0 grams. This amount is enough for the entire life of the halogenator. The mixer 7 is powered by an electric motor 8 and is mounted on its axis with the possibility of rotation for mixing and grinding pharmacopoeial salt. Grinding is achieved by moving salt crystals in the bowl of the mixer 7, and also due to microvibrations that occur during operation of the electric motor 8. Additional grinding of the pharmacopoeial salt to microdimensions is achieved by performing a step 13 in the conical bowl of the mixer, which salt crystals break when rotated. The special form of the mixer 7 and microvibrations that occur during the operation of the electric motor 8, allow you to better mix the salt even when it is caking, as well as produce an additional tactile effect.

The duct 2 extends vertically along the axis of the housing 1. The duct 2 connects (through the air channels 15, the hole 21 in the valve 17) the chamber 6 of the housing with the outer air channel of the mouthpiece 3.

Air duct 2 enters the mouthpiece of the mouthpiece 3, the axis of the air channel of the duct 2 and the air channel of the mouthpiece 3 are the same. The mouthpiece 3 is mounted on the housing with the possibility of separation and removal. The mouthpiece 3 and the housing 1 are connected using latches 14. A threaded connection of the mouthpiece and the housing is possible. Between the salt chamber 6 and the air duct 2, air channels 15 are made, connecting, while the button 9 is pressed, the chamber 6 of the housing 1 to the air channel of the mouthpiece 3 through the opening 21 in the valve 17. The mouthpiece has lateral air channels 22 through which air flows from the atmosphere.

One pole of the battery 5 (battery) is connected to the electric motor 8 via terminal 10. The second pole is connected to the electric motor 8 by a spring terminal 4, which is closed when the button 9 is pressed.

As you know, salt is a very good adsorbent, therefore, to prevent the salt from absorbing moisture during storage, silica gel is used, a small amount of which is placed in the chamber for silica gel 18. The ingress of silica gel into the salt suspension is completely eliminated by the use of a filter pad 19, which can only pass air , to remove moisture from it with silica gel.

Pharmacopoeial salt weighing 1.0 gram is already present in the chamber 6 of building 1 of the industrial halogenator; therefore, salt is not required before using the halogenator.

Portable haloengulator works as follows.

The total duration of the halogenator is 60 minutes, the duration of one session is 2 minutes. During the session, the patient inhales from 2 to 4 mg of NaCl per minute and from 4 to 8 mg of NaCl per session, respectively. Number of use sessions 30.

In the off state, the salt is at the bottom of the chamber 6 of the housing, all air channels through which air can enter the chamber are blocked. Only the openings 20 connecting the silica gel chamber 18 and the casing chamber 6 remain open to allow moisture to be adsorbed inside the casing chamber.

Before using the haloengulator, the protective cap 16 is removed.

When the button 9 is pressed, the holes 20 connecting the silica gel chamber 18 and the housing chamber 6 are closed, while the hole 21 connects the channels 15 and the air duct 2, the electric motor 8 starts to rotate and stir the salt with a mixer 7. The speed and shape of the mixer 7 are such that in the process of mixing the salt, its small particles are formed.

Air channels 15 between the air duct 2 and the housing chamber 6 pass into the air duct 2 through the opening 21 in the valve 17 only salt particles of the smallest fractions (respiratory fraction 0.5-5 μm, 70-91%).

The user holds the button 9 and takes a deep breath, leaning the mouthpiece 3 to his lips.

The haloengulator weighs only 50 g and fits in the user's hand. During use, the haloengulator is held vertically or at an angle of maximum 30 degrees with two fingers, the forefinger is pressed from above, and the large one is pressed by pressing button 9 on the side. Air enters the housing chamber through the lateral air channels 22, the silica gel chamber 18, mixes with salt particles and enters the air duct 2 through the air channels 15 (this process is schematically shown by arrows in Fig. 4). The resulting salt suspension enters the mouthpiece 3, from where it is supplied to the respiratory tract together with an additional air stream (see Fig. 4). Small fractions of salt settle on the surface of the bronchioles of the lungs, producing a therapeutic effect.

Exhalation is through the nose. The user naturally breathes in and out for 2 minutes. After the procedure expires, the haloengulator button is released and the mouthpiece is removed from the mouth. The protective cap is put on again and the halogenator is placed in the packaging.

The advantages of a haloengulator are as follows:

1. Particles of the respiratory fraction (4-9 microns) are created, which increases the efficiency of the procedure and allows you to reduce one session to 2 minutes, and the amount of inhaled salt to 8 mg / session.

2. A small amount of salt per session allows you to create a lightweight, portable and stand-alone device.

3. This type of haloengulator is disposable, therefore salt replacement in the chamber or batteries is not provided, salt and battery charge are used almost completely, the used haloengulator must be disposed of.

4. For ease of use and storage, the mouthpiece is made vertical and removable. After use, the mouthpiece can be removed, washed and disinfected separately from the inhaler body.

5. The protective cap protects the mouthpiece from contamination during storage of the haloengulator.

6. A button for convenient pressing is located at the top of the haloengulator. When the protective cap is on, the button cannot be pressed, which prevents the motor from being accidentally started.

7. The silica gel chamber serves to prevent the absorption of salt by moisture. During storage, silica gel is used, a small amount of which is placed in a silica gel chamber. The ingress of silica gel into the salt suspension is completely eliminated by the use of a filter pad, which is a fine mesh and is located directly inside the silica gel chamber.

8. The valve associated with the button, depending on whether the button is pressed or not, opens / closes certain air channels: in the off state (the button is not pressed), all air channels through which air can enter the salt chamber are closed. The openings connecting the silica gel chamber and the salt chamber are open to ensure moisture adsorption inside the salt chamber; in the on state (by pressing the button), the holes connecting the silica gel chamber and the salt chamber overlap. Side air channels in the housing open through which air enters the salt chamber. And the central hole opens, through which the salt suspension from the salt chamber enters the airspace inside the mouthpiece and, mixing with atmospheric air, during inhalation, the patient enters the respiratory tract.

9. The haloengulator can be made of well-known elements and materials approved by the industry and approved for use in medical technology.

The invention is not limited to the specific embodiment shown in the description and shown in the drawings, but can be implemented in all possible types of variations without departing from the scope of the claims.
