Description

The utility model relates to devices for influencing the patient's respiratory system using gases.

In medical practice, inhalers are used to deliver nebulized drugs into the patient's respiratory system.

At present, hydrogen breathing apparatus are being proposed that generate hydrogen by the electrolysis of water. Japanese and Chinese scientists believe that the rationale for using hydrogen for medicinal purposes is the elimination of free radicals (unstable forms of oxygen) from the body by reacting free radicals with inhaled hydrogen and releasing the resulting water. Such devices are the Japanese products La Briller Elan, H2 Aroma Generator Dr. Shuto, Korean PREMIUM-3 breathing apparatus.

The technical solutions are presented in published patents of Japan, China, USA, Russia and international patent applications. A common feature of these technical solutions is a method of producing hydrogen by exposing water to metal.

Known therapeutic hydrogen apparatus according to patent CN 109224237, 2018, containing a housing in which are placed electrolysis cells with water, a safety monitoring system, a cooling device, a pump for water supply and devices for cleaning and humidifying gas. The device is structurally complex and is intended for use in a medical institution under the supervision of a specialist.

The same complex device for producing a gas mixture of hydrogen with atomized gas is presented in Russian patent No. 2701736, 2018 (priority 14.10.2015, China).

In the applications for the grant of patents WO2018047889 and WO2018151286 (Japanese Patent No. 6530151), an apparatus for hydrogen inhalation is presented, which, in addition to the electrolysis cell, contains a control unit for the power supply.

In US patent No. 9623204, 2017 (priority 2013), an electrolysis device for producing hydrogen from water is presented. In addition to the electrolysis cell, it provides a container for a limited volume of produced gas, an ion flow limiting module in the form of a metal mesh dividing wall, an electrolyte temperature control device and a connected DC electric current source.

All of these devices are not only structurally complex and difficult to use, but also very expensive.

A simpler design of a portable electrolytic inhaler is presented in CN 110408948, 2019, and is adopted as a prototype of the claimed utility model.

This device contains a tank body and an electrolytic module located at the bottom of the body. The power supply unit is installed under the reservoir and includes a battery and a control unit containing a battery charging circuit, switches, an output connector and a current indicator. The electrolytic module contains an anode with a nickel or nickel-plated alloy grid, a cathode with a titanium-platinum alloy grid. An alkaline aqueous solution of potassium hydroxide or sodium hydroxide is used as an electrolyte. In the upper part of the body there is a hole for water injection and a branch pipe for the gas mixture outlet. The inhaler uses a gas purification module containing a catalytic layer of active expanded clay and a waterproof membrane. This module, in addition to cleaning hydrogen and oxygen gases from electrolyte traces, generates negative oxygen ions.

With all the simplicity of the inhaler design, it cannot be argued that the device is affordable for the user, given the cost of the materials used. In addition, the materials of the patent do not indicate the ratio of the volume of the reservoir and the volume occupied by the electrolyte, that is, the allowable volume of gas in the free space of the reservoir is unknown, which does not guarantee safety for the user.

The author of the claimed utility model was faced with the task of creating a device that is simple in design, convenient and safe to use, and affordable.

The task was solved as follows.

The inhaler contains a sealed housing with electrolyte, an anode and cathode immersed in the electrolyte, and an electrical power supply. Water was used as an electrolyte. The body is made in the form of a hollow closed cylinder with a branch pipe. A rod is placed in the body cavity, which has a cross-section along its entire length. The anode is made of stainless steel wire and the cathode is made of annealed steel wire. The anode and cathode wires are wound on a rod in the form of two alternating spirals with a constant gap between the turns. The first ends of the wires are fixed on the upper part of the rod, and the second ends of the wires are brought out to the terminals of the electrical connector fixed to the body. The body is filled with purified water for 99% of the body volume. In addition, the body and stem are made of a neutral transparent material - polypropylene. The power supply plugged into the electrical connector is a low-voltage DC power supply.

The essence of the proposed technical solution consists in the activation of the metal passivated with an oxide film in water while passing a direct electric current. An oxide film on the cathode is obtained by firing a steel wire.

The technical effect of the utility model is the simplicity of the design and the availability of the materials used - pure water, steel wire and a standard power supply. In addition, the device is compact and safe due to its low gas volume and can be used in any room with a standard power supply.

The technical solution is illustrated by drawings.

The specific implementation of the claimed device was as follows.

A medical syringe with a capacity of 150 ml made of polypropylene was used as the body 1 of the device. The sealing disc was removed from the syringe piston, and the edges of the rod 2 were notched along the entire height with a gap of 2 mm for laying the wires of the anode 3 and cathode 4. Three thin wires (diameter 0.5 mm) of stainless steel AISI 304 were twisted together, a twist with a length of 1.25 m for anode 3 was obtained. For cathode 4, a twist of three wires of the same brand with a length of 1.25 m was made in the same way and fired on a gas burner: firing made it possible to obtain a uniform oxide film on the surface of the steel twist ... The first ends of the twists made were fixed on the upper part of the rod 2. Then the twists were alternately wound onto the ribs of the rod 2 along the previously applied notches so that the twisting of the anode 3 alternated with the twisting of the cathode 4, while a constant gap of 2 mm remained between adjacent turns, and the pitch of each the spiral was 4 mm. In total, 12 turns of each spiral were made, in height this was approximately 65 mm. After that, the rod 2 was inserted into the housing 1 and the second ends of the twists of the anode 3 and cathode 4 were brought out to the terminals of the electrical connector 5 (plus and minus, respectively). Connector 5 is fixed on body 1. Further, body 1 was tightly closed from below with a sealing disk 6 and through the nozzle 7 was filled with water 8 to 98-99% of body 1 volume so that there was a small free space 9 under the upper cover of body 1 for the gas mixture. A branch tube, namely a nasal cannula, was connected to the branch pipe 7.

The assembled device was mounted vertically on the table surface, and a power supply (not shown) was connected to the connector.

The device was tested in order to determine the optimal mode of operation when using water of various qualities.

The following results were obtained.

When using ordinary tap water, the process of gas evolution proceeded very intensively and quickly (3-5 min.), A plaque appeared on the inner surface of the case, the water became cloudy, and after 15 minutes the case became significantly heated.

When using filtered or bottled water, the process was less intense, the water became cloudy after 15-20 minutes, and the body was heated slightly after 25-30 minutes.

When distilled water was used, the process of gas mixture evolution was calm, the water remained transparent and did not heat up for 40 minutes.

It is known from practice that therapeutic procedures are carried out with a gradual increase in duration. Therefore, it can be concluded that it is preferable to use purified or distilled water in such an inhaler.

In addition, it turned out that the process of gas mixture evolution occurs more calmly when connecting a power supply with a voltage of 12 V and a current of 1A than a power supply with a voltage of 9V and a current of 3A.

Thus, the claimed useful model of an inhaler is workable and suitable for use in therapeutic practice.

The technical result consists in the implementation of obtaining a gas mixture for breathing by means of a very simple design of the inhaler, which is distinguished by ease of use, safety and affordability.
