Description

The utility model 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.

Mechanical devices for warming inhaled air generate an air flow to provide respiratory support to the patient in the form of prescribed therapy. This therapy is applied through various interaction devices that are attached to the patient, such as a nasal mask, full-face mask, etc.

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

In this regard, the purpose of the proposed utility model is to simply create and maintain a given temperature of inhaled air on a portable device for heating inhaled air, which is optimal under certain circumstances during periods of exacerbation of diseases.

The prior art includes patent RU 2687990 C1, 17.05.2019, which discloses a half mask for protecting the respiratory system and face from abnormally low temperatures, comprising a housing with a nasal groove and an outwardly protruding part with a central opening, characterized in that the housing, made of dermatologically safe plastic with low thermal conductivity, has a silicone gasket along the contour of contact with the face, two inhalation valves and two exhalation valves are located on the outside, one of which has a locking mechanism, inside the half mask contains a partition on which one exhalation valve and two inhalation valves are located, the partition divides the interior of the half mask into a small and a large chamber, in the large chamber there are parallel bending tubes made of a material with high thermal conductivity, with a cross-section of 15 mm with side ribs 2 mm high and internal corrugations 1.5 mm high and with a pitch of 12 mm, in the lower part of the small chamber there is a collection tank condensate, having a lid covered with 2 mm holes.

The disadvantage of this solution is the inability to control, set and adjust the air supply temperature, weak air heating, as well as the complexity of the design of the device based on the principle of a tubular recuperator.

The prior art includes a patent selected as a prototype RU 2787161 C1, 29.12.2022, owned by the author, disclosing a portable device for heating inhaled air, which includes a controller containing a temperature control unit, an air pipeline with inlet and outlet openings, including a heating element, an inhaled air temperature sensor located at the end of the outlet opening inside the air pipeline, as well as a mask fixed at the end of the outlet opening, including an inhalation valve and an exhalation valve, the device additionally includes a body temperature sensor, made with the possibility of its fixation on the human body, wherein the inhaled air temperature sensor and the body temperature sensor

interact with the controller to transmit body temperature and inhaled air temperature to it, to regulate the inhaled air temperature in real time.

The disadvantage of this solution is the complexity of its design and the large size of the device.

The basis of this utility model is the task of developing a design for a portable device for heating inhaled air that eliminates the above-mentioned disadvantages of known devices.

The technical result is a simplification of the design of a portable device while maintaining its compactness.

This technical result is achieved in that the portable device for heating inhaled air includes a half mask designed with the possibility of its adhesion to the user's face, containing a unit for fixing it on the head, an exhalation valve for removing exhaled air, as well as an inlet pipe located in the opening of the half mask, ensuring the flow of inhaled air through it, where

the inlet pipe includes a fan installed inside it, providing forced air flow, as well as a radiator heating unit with heating fins,

wherein the device is provided with a control unit located on the surface of the inlet pipe for controlling and monitoring the temperature, including a power element interacting with a fan and a radiator heating unit,

a temperature sensor located in the area of the supply air passage after the radiator heating unit, designed with the ability to monitor the temperature and transmit it to the control unit.

The control unit is controlled by a temperature controller located on the inlet pipe.

The half mask fixing unit is made in the form of an elastic band.

The exhalation valve is made in the form of a pair of holes.

A portable device for heating inhaled air is a device that ensures its use while moving, in motion, that is, it is a mobile device.

The portable device for heating inhaled air includes a half mask 1 made as a respirator, designed to fit the user's face, covering the respiratory organs, i.e. the nose and mouth. The half mask 1 contains a unit for fixing it on the head 2, made, for example, in the form of an elastic band, going around the head from behind (the back of the head), or else have a more complex mechanism for fixing it on the head, for example, in the form of three straps (left, right, top), tied at the back of the head, reducing the slipping of the half mask 1 from the face. In this case, it is preferable to additionally equip the half mask with a nose clip, fixing it motionless on the user's nose.

The half mask 1 contains an exhalation valve 3, located near the nose, for the release of exhaled air. One or a pair of openings at the top in the nose area and at the bottom in the mouth area in the half mask 1 can be made as an exhalation valve 3, for the release of exhaled air, as well as excess air coming from the outside. In addition, the exhalation valve 3 can be made as a more complex release mechanism, for example, as an outlet petal membrane that releases air when its excess is created in the half mask.

The half mask 1 comprises an inlet pipe 4, which ensures the flow of inhaled air through it, located in the opening of the half mask 1. The inlet pipe 4 is made of a rigid or semi-rigid material and has the shape of a preferably circle, or as shown in Fig. 1, 2, a square with rounded edges. The inlet pipe 4 on the side farthest from the half mask 1 may have an edge directed inward to fix the fan 5 to it and prevent it from falling out, which further simplifies the design of the device.

The inlet pipe 4 includes a fan 5 installed inside it, providing a forced air flow. The blades of the fan 5 ensure the capture of outside air and forcibly direct it inside the half mask 1. The fan 5 is attached to the edge of the inlet pipe 4 or is in contact with its edge, as indicated above.

The inlet pipe 4 includes a radiator heating unit 6 installed inside it, having heating fins and powered by a power element (not shown in the figure), which will be discussed below. The design of the radiator heating unit 6 may be different, but must ensure heating of the heating fins (plates) for heating the air passing through the heating fins of the radiator heating unit 6.

The power element is made, for example, in the form of a battery element placed in the control unit (not shown in the figure). The power element can be either rechargeable or replaceable, like batteries.

The power element interacts with the fan 5 and the radiator heating unit 6, providing them with power for heating and blowing air.

The device includes a control unit for controlling and monitoring temperature, interacting with temperature sensor 7.

The control unit controls the temperature and, optionally, the rotation speed of the fan 5. The control unit interacts with the temperature sensor 7, decreasing/increasing the heating value of the radiator heating unit 6, for example, increasing or decreasing the voltage, or the power supply to the radiator heating unit 6 can be pulsed, taking into account the readings of the temperature sensor 7. The control unit can be placed on the surface of the half mask 1 or the surface of the inlet pipe 4. The control unit can also be made as a separate part connected by wires to the nodes of the device.

The device also includes a temperature sensor 7, located in the area of the supply air passage after the radiator heating unit 6.

Temperature sensor 7 is designed with the ability to monitor temperature and transmit it to the control unit. Control unit 7 reads the temperature sensor 7 in real time, adjusting the heating depending on the set temperature.

The control unit can either be connected to a temperature controller (not shown in the figure) located on the inlet pipe 4 to set the desired temperature, or the control unit can be designed with the ability to be controlled remotely via wireless communication (e.g. WI-FI, IR (infrared), Bluetooth, GPS and other data transmission technologies/protocols), for example via a telephone paired with the control unit.

The use of an inlet pipe 4 in the half mask 1 with the working units of the device located in it (fan 5, radiator heating unit 6, temperature sensor 7) ensures a simplification of the design of the portable portable device while simultaneously making it compact, and also eliminating the complex control elements inherent in analogues. The design of air heating and its supply to the user is maximally simplified while operating correctly and performing the function of heating the inhaled air.

The operating principle of the first version of the device is as follows:

The control unit sets the required air heating temperature using a temperature controller or wirelessly from an electronic device (phone, tablet, etc.).

The user puts on half mask 1 and secures it to the head with fixing unit 2.

Fan 5 captures (sucks in) air and drives it through inlet pipe 4 through radiator heating unit 6.

The air, passing through the radiator heating unit 6, is heated.

Temperature sensor 7 reads the incoming temperature and sends a signal to the control unit, which controls the radiator heating unit 6 and increases or decreases the heating, depending on the set temperature and the temperature on the temperature sensor 7.

The user inhales heated air.

Exhaled air is released through exhalation valve 3.

The cycle repeats.
