Description

The invention relates to the field of medicine, namely to devices for conducting physiotherapy through inhalation, and can also be used in the treatment and prevention of respiratory diseases.

Known solution US20210339058 A1 "Smart mask with a transparent part covering the mouth and air filtration using an impeller" with at least one impeller-driven air filter and at least one passive air filter, while the air filters are in fluid communication with the space between the transparent part and the human mouth. Air can be drawn into the mask through an impeller-driven air filter, primarily by the impeller, but air enters or exits the mask through a passive air filter by human breathing.

The disadvantages are the complexity of the design, the possibility of using only in the form of a mask worn on a person's face. There is no possibility of heating the air entering the mask, the air enters both through the filter in the tube and through the filters in the mask itself. Thus, the device is unable to warm up the breathing air, cannot be used as a desktop device, i.e. it can be used for a long time, it is therefore inconvenient to use, has a design complexity, i.e., is laborious.

Known solution US20050150501A1 "Therapeutic device for the local treatment of colds" in particular, in the nasal cavities, frontal sinuses and throat area with ionized heated air flow, heated at least to the temperature of the human body and acting directly and locally in a limited way through the nose on the epithelium of the nasal cavities and nasal cavities. The device comprises: a L-shaped housing containing: a cold air intake site, a warm air injection side, a device for creating an air flow between the cold air inlet site and the warm air outlet side; an adjustable heating device for heating the air flow between the inlet portion and the discharge side; and a replaceable housing containing crystallized salt, wherein the warm air flow collides with said housing before exiting said housing.

The disadvantages are the complexity of the design, the possibility of using only in contact with the nose or mouth of a person. The air goes in a short straight path, which requires a stronger heater, the fan is installed in the corner of the L-shaped housing, the heater is installed inside the housing after the fan, which leads to the combustion of oxygen. Thus, the device cannot be desktop, i.e. be used for a long time, it is therefore inconvenient to use, air heating is not effective, it has a design complexity, i.e. laborious.

Known solution CN 201042552 Y "Humidifier exhaust pipe" includes a tube through which humid air flows, a heating element is dressed on the tube: consisting of two sheets equal in length to the length of the tube, and in width equal to the diameter of the tube, along the long edges having parts of a zipper. A heater is located between the fabric sheets in the form of a coil.

The disadvantage is that the tube does not have an air blower, the inability to change the shape of the tube, the air flows in a straight line, the heating element, if used on a tube, which has the ability to bend and lengthen or shorten, is not able to repeat this and, accordingly, heat the air efficiently. Thus, the device is inconvenient in operation, air heating is not effective, it has a design complexity, i.e. laborious.

Known solution No. 2239461 "Apparatus for breathing air", IPC A61M 16/00, containing a breathing tube connected to a heat-insulating housing, in the bottom of which holes are made for communication with the atmosphere, a heating element enclosed between perforated plates, which are placed in the housing with the formation gaps with its walls; The air mixture formed by pulling up the main flow of the side air flow has a therapeutic and prophylactic effect on the respiratory system.

The disadvantage of this technical solution is the absence of a fan or other air-forcing device, which can lead to difficulty breathing during operation of the device due to the relatively high resistance to the flow of air passing through the holes. The next disadvantage is the possibility of getting too much dehydrated air, which will dry out the mucous membrane. Another disadvantage is the relatively high complexity and laboriousness of manufacturing the structure due to the complexity of the shapes of the parts, as well as their number, interfacing, etc.

Of the known technical solutions, the closest in purpose and technical essence to the claimed object is the solution SU 35329 A1 "Device for obtaining heated air for breathing by patients", IPC A61M 15/00, containing an electric fan with a motor and a switch, an appendage attached to the electric fan, with a number of conical coils located inside it. Coils are designed to circulate hot water, hot air or steam inside them. The water circulating through these coils comes from a heating box equipped with a heating electrorheostat. From the box, water, through a pumping device, enters the coils through tubes with control valves that allow you to turn on or off any of the coils. Separate coils can also be connected to drug reservoirs and provided with holes along their spirals, through which certain medical drugs in a liquid or vapor state can be injected into the air stream. Thermometers are installed in the valves to measure the temperature of incoming drugs.

The disadvantage of this technical solution is the relatively high complexity and laboriousness of manufacturing the structure due to the large number of parts, as well as the need to ensure the tightness of the connecting nodes of the coils with thermometers, valves, water containers, etc. The next disadvantage is the bulky design and relatively large weight. The next disadvantage is the difficulty in operation due to the lack of the ability to automatically maintain the temperature of the breathing air. Another disadvantage is the inability to adjust the speed of the electric fan.

The technical task is to reduce the size of the device, ease of use, reduce labor intensity.

The essence of the invention

The technical problem posed is solved by the fact that the desktop device for the treatment of SARS and Covid (hereinafter referred to as the desktop device) includes a pipe made of complex shape, a heating element installed outside the pipe along its entire length, a fan installed on the side of the air intake. A frequency converter is also provided for changing the speed of the fan impeller for the ability to adjust the air supply force, a temperature sensor and an automatic temperature control unit. The device is mounted on a tripod, covered with a fabric cover, on which attachments are fixed.

The desktop device includes the following main elements: pipe (1) fan (2), frequency converter (2.1), heating element (3), temperature sensor (3.1), temperature control unit (3.2), power supply.

Pipe (1) Fig. 1 is the basis of the desktop device and serves to intake and heat the breathing air passing through it. Pipe (1) is made of thin-walled, for example, corrugated food grade stainless steel or aluminum or copper. The pipe (1) has a complex Z-shape containing at least one bend of FIG. 1. In a particular case of execution, the pipe (1) may have a complex shape in the form of a horizontal spiral containing at least one turn of FIG. 2. In another particular case, the pipe may have a complex shape in the form of a "serpentine" containing at least one loop of FIG. 3. The use of the above types of forms is due to the need for the most efficient heating of the breathing air passing through the pipe. Bends (loops) increase the path covered by the air flow, and also slow it down, which contributes to its maximum heating in a relatively short period of time. The corrugated surface of the pipe (1) increases the efficiency of air heating, increasing the heat exchange area. It is possible to make a pipe of various zigzag shapes from a corrugated pipe, which allows the design to be made compact.

In a particular case of the execution of the pipe (1) of Fig. 1 Z-shaped. In a particular case of the execution of the pipe (1) of Fig. 2 in the form of a horizontal spiral. In a particular case of the execution of the pipe (1) of Fig. 3 in the form of a coil.

On the end part of the pipe (1) of Fig. 1, on the air intake side, there is a branch pipe with a flange (1.2) for fastening the fan (2), which is closed by a safety grille (not shown in the figure). The spigot flange (1.2) is made, for example, of plastic or some light metal alloy. A branch pipe with a flange (1.2) is fixed on the pipe (1) of Fig. 1 by means of, for example, an interference fit or collar. To install the fan, through holes are made on the flange so that the rotation axis of the fan (2) of Fig. 1 was coaxial with the imaginary axis of the pipe (1) of FIG. 1. In a particular case, the holes can be threaded.

To regulate the air flow rate, the fan (2) of FIG. 1 is connected to the frequency converter (2.1) of FIG. 3.

The heating element (3) of Fig. 1 is made of conductive materials such as, for example, a wire helix or glass fiber resistive tape. The materials of the heating element (3) have a flexible structure, thereby ensuring uniform laying by winding like a spring from the outside around the pipe (1) and along its entire length. The laying method described above ensures uniform heat transfer along the entire length of the pipe (1). The heating element (3) is automatically controlled by the temperature control unit (3.3) of fig. 1-3.

Outside the pipe (1) of Fig. 1 with the heating element (3) of FIG. 2 is covered with a cover (3.1) of fig. one.

A temperature sensor (3.2) of Fig. 1, 2, which is connected to the temperature control unit (3.3) of FIG. 1, 2. The temperature control unit (3.3) serves to control and maintain the required temperature regime for heating the breathing air. The temperature control unit (3.3) is equipped with temperature setting buttons and a digital display that shows the temperature. The operating scheme of the temperature control unit (3.3) is a feedback system and operates on the principle of a two-position relay. The temperature control unit (3.3) receives a signal from the temperature sensor (3.2), processes it and sends a control pulse to the actuator, i.e. the heating element (3).

In a particular embodiment, the device may be equipped with a non-contact thermometer for measuring the user's body temperature. This scheme provides the user with breathing air heated to the temperature of his body. The non-contact thermometer measures the user's body temperature according to the pyrometer principle and sends a signal to the temperature control unit (3.3). The temperature control unit (3.3) sends a control pulse to the heating element (3). When the air warms up to the required temperature, the temperature sensor (3.2) sends a signal to the temperature control unit (3.3). Next, the relay resets or the electronic key is locked and the heating element (3) is turned off.

All electrical devices installed on the desktop device for the treatment of ARVI and Covid are powered from the mains via a wire (4) or operate from an independent power supply.

Case (5) fig. 3, 4, in addition to performing an aesthetic and heat-shielding function, it serves to secure attachments.

Outside, the cover (5) of Fig. 2, 3 is equipped with places for fastening the frequency converter (2.1) of fig. 1, 2 and the temperature control unit (3.3) of fig. 1, 2. Also on the outer side of the cover (5) there is a pocket (5.1) of FIG. 3 which serves to store the wire (4) in the transport state or during the period when the device is not in operation.

To fix the desktop device on a solid surface, a tripod (6) of Fig. 1-4, which consists of the base (6.1) of Fig. 1 and supports (6.2) of fig. 1. The base (6.1) in the form of a round or rectangular platform is made, for example, of plastic or metal. In the center of the base (6.1) there is a seat for installing the support (6.2). The support (6.2) is a vertically mounted bar, for example, of round section, made of metal or reinforced plastic. The support (6.2) is fixed to the base (6.1) by means of a threaded connection or, for example, an interference fit. In the upper part of the support (6.2) there is a fastening (6.3) of Fig. 1 in the form of a clip for fixing the pipe (1) of FIG. one.

The technical result of the invention is to increase the efficiency of air heating, reduce the size of the device (use of a zigzag pipe), ease of use (desktop design, automatic maintenance of air temperature), reduce labor intensity (there are no complex components that require tightness)

Implementation of the stated solution:

The claimed technical solution works as follows. Before starting operation, the user needs to prepare the device. To do this, the user must place the desktop device on a hard, level surface, such as a table. Next, remove from the pocket (5.1) of Fig. 3 wire (4) and connect it to the mains.

Further, the user, using the buttons located on the temperature control unit (3.3) of Fig. 1, 2 sets the required temperature, the values of which are displayed on the digital display. Further, the user, by turning the adjustment knob of the frequency converter (2.1) of Fig. 1, 2 sets the required speed of the fan impeller (2) of FIG. 1. For a short period of time, the heating element (3) of FIG. 2 heats the wall of the pipe (1) of Fig.1. Forced by the fan (2) of Fig. 1, the air flow warms up as it passes inside the pipe (1) of FIG. 1. Temperature sensor (3.2) of fig. 3, installed at the outlet of the pipe (1), reads the temperature readings of the degree of heating of the air and sends a signal to the temperature control unit (3.3). After processing the signal, the temperature control unit (3.3) continues to supply power to the heating element (3) if the temperature of the heated air is insufficient, or it interrupts the operation of the heating element (3) when the heated air reaches the set temperature.

Next, the user makes several test breaths of heated air coming out of the pipe (1). If necessary, the user adjusts the temperature using the buttons of the temperature control unit (3.3), and the intensity of the air flow using the frequency converter (2.1).

Further, when the required parameters for the temperature and intensity of the injected air flow are reached, the user begins the treatment procedure, namely, he takes even deep breaths through his mouth and exhales through his nose.
