Description

The invention relates to the field of medicine, namely to devices for physiotherapy and can be used to influence the mucous membranes of the human upper respiratory tract, for the prevention of pulmonary diseases.

The known solution is SU 35329 A1 “Device for producing heated air for breathing by patients”, IPC A61M 15/00, containing an electric fan with a motor and a switch to which an appendage is attached, inside the appendage there is a number of conical coils with hot water, hot air or steam flowing inside them . The water circulating through these coils comes from a heating box equipped with a heating electric rheostat. From the box, water through a pumping device enters the coils through pipes with control valves that allow you to turn on or off any of the coils. Individual coils can be connected to reservoirs of medicinal preparations and equipped with holes in their spirals, through which certain medicinal preparations 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 inability to use the device to obtain heated air for breathing when moving and performing manipulations over objects. (SU 35329 A1, http://new.fips.ru).

The known solution is RU 2696759 C1 “System for individual healing of air spaces with volatile substances using natural carriers”, MPK A61M 15/00, containing a receiving funnel which is a thin-walled elastic structure made of dense woven or polymer film material. Due to its wide edge, the receiving funnel is permanently attached to the forming hoop. From the inside, a flat cross with a central hole is supported on the hoop with the possibility of fixing it on the hoop along the inner diameter. A fan with an autonomous power source is placed in the central hole of the flat cross through a damping rubber gasket. The other edge of the receiving funnel rests with its edge on the flange of the threaded pipe and is pressed against it through a washer with a nut. At the same time, with the help of adapters, the air vent in the form of a flexible hose is connected at its ends to a pipe and a device for individual health in the form of a mask. In turn, the pipe is equipped with a detachable flexible suspension using a clamp.

The disadvantage of this technical solution is the inability to use this device when the user moves. (RU 2696759 C1, http://new.fips.ru).

Of the known technical solutions, the closest in technical essence to the claimed object is solution RU 2116807 C1 “Inhaler”, MPK A61M 15/00, containing a housing with an air duct, a heating element connected to a thermostat and temperature sensor, and a mixing tank. A fan with an electric drive and a device for whipping the medicinal solution, which allows obtaining a finely dispersed medium and increasing the evaporation surface, is inserted into the upper part of the mixing tank through a sealing gasket. A heating element is placed under the mixing tank, connected in series with a temperature regulator located on the inhaler body and a temperature sensor located in the medicinal solution, and the air duct is connected to a socket, in the narrow part of which there is a hole, through a valve for delaying the flow of the air-medicine mixture and suction of clean air.

The disadvantage of this technical solution is the inability to use the inhaler when moving and performing manipulations over objects. (RU 2116807 C1, http://new.fips.ru).

The problem that the claimed solution is aimed at is the development of a convenient design of a breathing air heater that does not limit the user’s movements and the possibility of using it while the user is moving.

The essence of the invention

The problem is solved due to the fact that the breathing air heater contains a tube (1) FIG. 1, which is C-shaped, and one of its ends contains bends in perpendicular planes, forming vertical and horizontal sections of the tube, placing the outlet directed towards the nose and mouth of the user.

The breathing air heater includes a tube (1) FIG. 1 is C-shaped; in a particular case, the tube (1) has a corrugated side surface, one end of which has an inlet (2) with a fan (7) covered by a grille (not shown in the figure), and the opposite end of the tube (1 ) contains bends in perpendicular planes, forming vertical and horizontal sections of the tube, placing the outlet (3) directed towards the user's nose and mouth. This design allows the air heater to be placed on the user’s neck without limiting his movements. The fan (7) has the ability to adjust the rotation speed, which allows you to regulate the speed of air flow passing through the internal space of the heater tube (1). A heating element (8) is located on the outer surface along the entire length of the tube (1). The tube (1) is located inside a cover that follows the shape of the tube (1); in a particular case, the cover has a zipper. The cover serves as thermal insulation, and the zipper allows you to remove it from the tube (1), for example, for washing, without disturbing the integrity of the cover. The heater contains a temperature controller (5) with a thermocouple (4), and a fan (7) rotation speed controller (6). The thermocouple (4) is located in the internal space of the tube (1) closer to the outlet (3), and the regulator (5) and regulator (6) are located on the outer surface of the case in the area of the outlet (3) so that it is convenient for the user to perform settings. The temperature regulator (5) allows you to change the intensity of air heating. The fan (7) speed controller (6) allows you to adjust the air flow speed.

The technical result consists in creating a breathing air heater, the design of which does not limit the user's movements and makes it possible to use the heater during movements performed by the user.

Brief description of drawings:

in fig. 1 is a schematic representation of a breathing air heater. General form.

Brief description of structural elements:

1 - tube;

2 - inlet;

3 - outlet;

4 - thermocouple;

5 - temperature controller;

6 - fan speed controller;

7 - fan;

8 - heating element.

Implementation of the declared decision

The claimed solution works as follows.

The breathing air heater is placed around the user's neck so that the outlet (3) of FIG. 1 heater was directed towards the user's nose and mouth. The heating element (8) is turned on and the required air heating temperature is set using the temperature controller (5), and the speed of the air flow passing through the internal space of the heater is regulated using the rotation speed controller (6) of the fan (7). The fan (7) creates an air flow that enters the tube (1) through the inlet (2), moving along it, takes heat from its surface, and then leaves the inner space of the tube (1) through the outlet (3) in the area user's nose and mouth. The user inhales heated air, which enters the upper respiratory tract.

Claims (1)

A breathing air heater, including a tube with a fan in the inlet, a heating element with a temperature controller, characterized in that the tube is C-shaped, and one of its ends contains bends in perpendicular planes, forming vertical and horizontal sections of the tube, placing the outlet hole directed towards the user's nose and mouth.
