Description

The invention relates to medical equipment, namely to individual respiratory devices designed to protect the respiratory organs from the cold, as well as for the treatment and prevention of various diseases associated, in particular, with the human respiratory organs.

Inspiratory air warmers shape the airflow to provide support to the patient's breathing as prescribed therapy or for prophylactic purposes. This therapy is administered through various interface devices that are attached to the patient in the form of, for example, a nasal mask, a full face mask, etc.

In addition, it is known that an increase in temperature is a protective reaction of the body. At this time, the rate of biochemical reactions increases - with an increase in temperature by only 1 degree (from 36.6 to 37.6), this rate increases 10 times. Protective antibodies are formed faster, metabolic products are utilized faster, and thus the human body more effectively fights against the disorders that caused the temperature increase. Since most often an increase in temperature is caused by some kind of infection, in its evolutionary and biological essence, this process should be considered as a measure of protection against infectious pathogens.

In this regard, the purpose of the proposed invention is to provide and maintain a higher temperature of inhaled air on a portable portable device for heating inhaled air, under certain circumstances (for example, in severe frosts) and during an exacerbation of diseases.

The prior art patent RU 98686 U1, 10/27/2010, discloses an air heating device consisting of a filter box connected to a corrugated tube connected to a face mask, while an active electric heating element in the form of a spiral with high resistivity is placed in the corrugated tube , connected through a sealed electrical inlet and connectors with a portable battery for heating the coil, the inner hose space and, accordingly, the purified air sucked in by a person.

The disadvantage of this solution is the complexity of its design, the need for constant electrical energy, the impossibility of autonomous use of the device.

The closest analogue to the proposed solution is patent RU 2753030 C1, 08/11/2021, revealing a protective mask with a heat exchanger, containing a front part with an inhalation valve and an exhalation valve, made with the possibility of a snug fit to the user's face and covering the user's nose and mouth, mask fixation unit on the head in the form of straps, a filter element, a helmet, where the helmet is a heat exchanger and is made of three layers with at least two cavities formed between the layers: for inhaled air and for exhaled air, the inhaled air cavity has at least one hole for inhalation and is made with the possibility of heating the air from the natural temperature of the human head and from the temperature of the exhaled air, the cavity of the exhaled air has at least one hole for exhalation, the cavities also have at least one hole each, into which the inhalation and exhalation tubes are installed, connected respectively to the inhalation and exhalation valves, the inhalation port is equipped with a iltrom.

The disadvantage of this solution is its low efficiency, since the heat exchanger cannot provide sufficient heating of the air, the complexity of the design, the need to constantly wear a helmet, and possible condensation in the helmet area.

The basis of this invention is the task of developing a design of a portable portable device for heating inhaled air, eliminating the indicated disadvantages of known devices, and providing high efficiency of heating inhaled air with simultaneous autonomy of the device.

The technical result is to increase the efficiency of heating the inhaled air with the simultaneous autonomy of the device and the simplicity of its design.

This technical result is achieved by the fact that the portable portable device for heating inhaled air includes a mask containing at least two inhalation valves with connectors, as well as an exhalation valve, while at least two loops of tubes fixed on the vest and having entry holes at the bottom of the vest.

At the top of the tubes there is at least one sensor that informs about the temperature of the incoming air and/or a sensor that informs about the humidity of the incoming air.

The vest on the inside includes pockets for placing heat-accumulating elements in them, opposite the places where the tubes pass.

Heat storage elements are made on the basis of paraffins, made with the ability to release the accumulated heat.

Heat storage elements include a chemical composition with an activator that ensures their forced activation and heating at the right time for the user.

Next, the proposed invention will be discussed in detail with regard to the illustration, where in Fig. 1 shows a general view of the implementation of a portable portable device for heating inhaled air. Front view; in fig. 2 shows a general view of the implementation of a portable portable device for heating inhaled air.

1 - mask;

2 - inhalation valves;

3 - exhalation valve;

4 - tube;

5 - vest;

6 - inlet;

7 - sensor informing about the temperature of the incoming air;

7.1 - a sensor that informs about the humidity of the incoming air.

The portable portable device for heating the inhaled air includes a mask 1. The mask 1 is made, as a rule, as a respirator, but can be made in the form of a full-face mask.

The mask 1 contains at least two inhalation valves 2 with connectors, as well as an exhalation valve 3. Inhalation valves 2 are usually made on both sides of the exhalation valve 3. There can be, for example, four inhalation valves, for better air intake and increase its heating temperature.

At the same time, an appropriate number of tube circuits 4 are connected to the connectors of the inhalation valve 2. The tubes 4 are fixed on the vest 5, for example, sewn between its two layers or otherwise attached. The tubes 4 are located on the vest 5, for example, "snake", to increase the area of their placement on the surface of the vest 5. The tubes 4 have inlets 6 in the lower part of the vest 5, which serve for air intake. It is possible to place filter elements at the ends of the tubes 4 at the inlets 6 to ensure filtering of the incoming air.

At the top of the tubes 4, it is possible to place at least one sensor 7 that informs about the temperature of the incoming air and/or a sensor 7.1 that informs about the humidity of the incoming air. These sensors 7 and 7.1 are installed directly before the inhalation valve. These sensors monitor temperature and humidity parameters and inform the user about these parameters, for example, by sound and/or light signal or CMC on the user's phone or through a special application on the computer/phone or otherwise.

Alternatively, the sensor 7 informing about the temperature of the incoming air and/or the sensor 7.1 informing about the humidity of the incoming air can be placed outside the device, and the sensitive element (thermistor/thermal probe, etc.) is placed inside the tubes 4.

Alternatively, the vest 5 on the inside may include pockets for placing heat-storage elements in them, mainly opposite the passages of the tubes 4 (pockets and heat-storage elements are not shown in Fig.). Heat storage elements generate heat autonomously. They are used to heat the air, for example, in extreme cold or in conditions where a person needs to obtain a sufficiently high temperature of the inhaled air, which the device cannot produce without these elements.

Heat storage elements are made, for example, on the basis of paraffins, made with the ability to release the accumulated heat (passive heat accumulators). That is, being in a warm place (a room, a car, etc.), heat storage elements accumulate heat, and during operation they release it, heating the air in the tubes 4, thereby providing additional air heating.

Heat storage elements can also include a chemical composition that ensures their forced activation and heating, for example, by pressing on the element, the activator is turned on and the heat accumulator is heated, generating additional heat.

Based on the chemical composition, heat storage elements can consist, for example, of the following components: iron powder, water, activated carbon, natural minerals. Heat is released as a result of accelerated oxygen oxidation of iron when the heat storage element is activated.

Alternatively, heat storage elements based on the chemical composition can be made on the basis of a solution of salt compounds. A supersaturated saline solution with an activator can be used as a filler. For activation in each heat storage element, a corresponding element is installed - a trigger.

Example 1 of using the device.

The portable portable device for heating the inhaled air includes a mask 1 made as a respirator.

Mask 1 contains two inhalation valves 2 with connectors, as well as an exhalation valve 3.

To the connectors of the inhalation valve 2, two circuits of tubes 4 are connected, fixed on the vest 5 as shown in Fig.

The device includes two inlets 6 in the lower part of the vest 5.

The user puts on the vest 5, puts on the mask 1, puts on outerwear (for example, a jacket) over the vest 5. Inside the space, heat is generated from the human body. This heat heats up the air coming through the tubes 4. The longer the contour of the tubes 4, the more the air in them warms up as it moves up the contour. A person inhales warm air.

The heating of the inhaled air will be carried out only due to body temperature.

Example 2 of using the device.

The portable portable device for heating the inhaled air includes a full face mask 1.

Mask 1 contains four inspiratory valves 2 with connectors, as well as an exhalation valve 3.

Four loops of tubes 4 are connected to the connectors of the inhalation valve 2, fixed on the vest 5 (two loops behind (on the back) of the vest 5, two loops in front).

The device includes four inlets 6 in the lower part of the vest 5.

In the upper part of one of the tubes 4 there is a sensor 7 that informs about the temperature of the incoming air and a sensor 7.1 that informs about the humidity of the incoming air with a sound speaker and a light indicator that notifies of the critically low temperature of the incoming air.

Vest 5 on the inside includes eight pockets.

In the four pockets on the back of the vest 5 there are heat-accumulating elements based on paraffins.

In four pockets in the front part of the vest 5 there are heat storage elements based on a solution of salt compounds with an activator.

The user puts on the vest 5, puts on the mask 1, puts on outerwear (for example, a sweater and jacket) over the vest 5. Inside the space, heat is generated from the human body. This heat heats up the air passing through the tubes 4, in addition, air heating is also provided by heat-accumulating elements based on paraffins, placed in the back pockets of the vest 5. that the parameters of the inhaled air have dropped below the acceptable threshold. The user presses on the front heat accumulators, thereby putting them into operation by means of activators. Inside the space, additional heat is generated from these heat storage elements. This heat additionally heats the air passing through the tubes 4. After a short time, the temperature of the inhaled air rises.

The proposed device provides an increase in the efficiency of heating the inhaled air with the simultaneous autonomy of the device and the simplicity of its design.
