Description

The invention relates to the field of medicine, namely to devices for conducting physiotherapy using heated air.

State of the art

Known solution No. 2239461 “Apparatus for breathing air”, MPK A61M 16/00, containing a breathing tube connected to a heat-insulating body, in the bottom of which there are holes for communication with the atmosphere, a heating element enclosed between perforated plates, which are placed in the body to form gaps with its walls, a vessel made tapering towards the breathing tube and with a hollow bottom, with which it is installed on the upper perforated plate with the possibility of blocking its channels. The air mixture formed by the main flow of the side air flow has a therapeutic and preventive effect on the respiratory system.

The disadvantage of this technical solution is the possibility of receiving too much dehydrated air, which will dry out the mucous membrane. Another disadvantage is the relatively high complexity and labor intensity of manufacturing the structure due to the complexity of the shapes of the parts, as well as their quantity, interfacing with each other, and the inability for the user to carry the device with him, for example, while walking.

The invention is known SU 984481 A1 “Device for heating air for breathing”, IPC A61M 11/00, including a housing, a mask and a heat exchanger with a saturated methane hydrocarbon, the housing is made of elastic airtight material in the form of a vest, and the heat exchanger is made in the form of metal parts installed in the vest tubes connected by electrical conductors. The tubes are fixed in a holder made of elastic material. The heat exchanger is placed in a housing made of elastic, airtight material. The housing has an air intake window and terminals for connecting a power source. An air supply tube with a mask is attached to the body. The body is made in the form of a vest. placed under clothing using belts. The heat exchanger tubes are connected to each other by electrical wires.

The disadvantage of this technical solution is the possibility of receiving too much dehydrated air, which will dry out the mucous membrane. The next disadvantage is the absence of a fan or other air-injecting device, which can lead to ineffective air supply to the breathing zone or difficulty breathing when operating the device with a breathing mask due to the relatively high resistance to air flow.

Of the known technical solutions, the closest in purpose and technical essence to the claimed object is the utility model RU 98686 U1 “Air heating device for filter gas masks”, MPK A62V 7/10, consisting of a hose heater, a battery, a control unit and a component of the gas filter box device (PFC).

The disadvantage of this technical solution is the possibility of receiving too much dehydrated air, which will dry out the mucous membrane. The next disadvantage is the absence of a fan or other air-injecting device, which can lead to ineffective air supply to the breathing zone or difficulty breathing when operating the device with a breathing mask due to the relatively high resistance to air flow.

A technical challenge to solve the above-described disadvantages is to develop a design for a breathing air heater that will prevent dehydration of the air when it is heated.

The essence of the invention

The stated technical problem is solved due to the fact that the breathing air heater includes an air humidifier (9) containing a reservoir (9.1) with a capillary tube (9.3) and an ultrasonic membrane (9.2) installed in the upper part of the reservoir (9.1), while the humidifier air (9) is connected to the tube (1) in the area of the outlet (3) hole of the tube (1), and the ultrasonic membrane (9.2) is installed in the side hole of the tube (1), located in the area of the outlet (3) hole of the tube (1).

The breathing air heater contains a tube (1) of a curved shape, one end of which has an inlet (2) with a fan (7). The fan (7) has the ability to adjust the rotation speed. A heating element (8) is located on the outer surface along the entire length of the tube (1). In a particular case, the tube (1) is equipped with a breathing mask.

The heating element (8) is made of conductive materials such as, for example, a wire spiral or a resistive glass fiber tape. The materials of the heating element (8) have a flexible structure, thereby ensuring uniform installation by winding like a spring from the outside around the pipe (1) and along its entire length. The installation method described above ensures uniform heat transfer along the entire length of the tube (1). The heating element (8) contains a temperature regulator with a thermocouple (4) located in the internal space of the tube (1) before the humidifier (9). The heating element (8) is controlled automatically by the control unit (5).

The fan (7) is installed in such a way that the axis of rotation of the impeller is directed along the imaginary axis of the tube (1), as well as coaxially with it to ensure the movement of air flow along the tube (1). To make it possible to change the speed of the forced air flow, the fan (7) is connected to the control unit (5).

To avoid the supply of dehydrated breathing air, which can dry out the mucous membrane of the respiratory tract, the device is equipped with an air humidifier (9). The humidifier (9) is connected to a tube (1) in the area of the outlet (3) (The aerosol is directed directly to the user's mouth). The air humidifier (9) contains a reservoir (9.1) for water or, for example, a medicinal product, an ultrasonic membrane (9.2) made in the form of a piezoelectric element and installed in the upper part of the reservoir (9.1), a capillary tube (9.3) immersed in the reservoir (9.1 ) to supply liquid to the ultrasonic membrane (9.2). The ultrasonic membrane (9.2) is installed in the side hole of the tube (1), located in the area of the outlet (3) of the tube (1). The ultrasonic membrane (9.2) is designed to disperse liquid into an aerosol. When voltage is applied to the contacts, the ultrasonic membrane (9.2) vibrates at high frequency, creating a cavitation effect in which liquid is sprayed onto microparticles. The ultrasonic membrane (9.2) is connected to the control unit (5) via a connection connector, which allows you to control the vibration frequency of the membrane, thereby changing the dispersion of aerosol particles depending on the type of liquid.

The control unit (5) installed on the tube (1) controls and maintains the required temperature of the breathing air. The temperature control unit (5) is equipped with buttons for setting the temperature mode and a digital display for displaying the temperature indicator. Also, the control unit (5) contains a frequency converter for changing the vibration frequency of the ultrasonic membrane (9.2) and the rotation speed of the fan impeller (7).

Power supply (6) fig. 1, located on the tube (1) next to the control unit (5), has the ability to operate both from a household power supply and from an autonomous power source, which makes it possible to carry the device with you during operation.

The above-described embodiment of the invention does not limit the design options that are feasible without departing from the essence and scope of the invention.

The technical result consists in providing a supply of humidified air, which prevents overdrying of the mucous membrane of the respiratory tract.

Implementation of the declared decision

The claimed technical solution works as follows. Fill the reservoir (9.1) with water or the necessary medicine for inhalation. Connect the breathing air heater to a household power supply or to an autonomous power source, and start it while in the breathing zone. Adjust the air heating temperature using the buttons on the control unit (5). When the breathing air heater is turned on, voltage is simultaneously applied to the fan (7), the heating element (8) and the ultrasonic membrane (9.2), which, vibrating at high frequency, disperses the liquid on its surface into an aerosol. The air flow supplied by the fan (7) through the tube (1) is heated from the inner surface of the tube (1), heated by the heating element (8), and is then saturated with aerosol from the reservoir (9.1). At the exit from the outlet (3), the air flow forced by the fan (7) is dispersed into the breathing zone. Then take several deep breaths of heated air to assess the optimal temperature level. Next, if necessary, adjust the heating temperature parameter and air flow intensity.
