Description

The utility model relates to preventive equipment intended for individual bactericidal treatment of air entering the respiratory system from the environment, while breathing, using radiating semiconductor elements. In particular, it can be used to protect against influenza viruses. The mask can be used by both medical professionals and ordinary citizens.

Known individual filtering mask for air treatment, covering the mouth and nose. A special removable pencil case with a filter is attached to the mask, with which filtering and partial disinfection of the air entering the cavity under the mask are performed. See RF patent No. 2187232 "Therapeutic preventive mask", IPC A41D 13/11, publ. 08/20/2002 in the Bull. Number 23.

The well-known mask is not intended for individual protection against influenza, since a mechanical filter is not able to prevent the entry of viruses that can even penetrate through microscopic holes. In addition, soaking the filter cartridge with onion, garlic, and other extracts can cause allergies or asthma attacks.

Closer in technical essence and adopted for the prototype is an individual prophylactic mask for disinfection of air coming in while breathing through the nose from the environment, described in RF patent No. 40847 “Individual prophylactic mask”, IPC A41D 13/11), publ. 10/10/2004 in Bul. No. 28).

The known mask contains an emitter for bactericidal treatment of air, made on semiconductor elements, containing ultraviolet light-emitting diodes, means for attaching it, a power supply unit and an electric switching circuit.

The mask can be partially used to protect against influenza viruses, because it contains a semiconductor ultraviolet emitter, the light of which penetrates the air entering the nose.

The known device has a number of disadvantages.

1. If a person has a stuffy nose, then the use of a mask is impractical.

2. When walking fast or under heavy stress, a person breathes an additional mouth, which opens the way for microorganisms to enter the lungs.

3. Prolonged irradiation of the nasal cavity with an emitter can lead either to damage to the mucous membrane with hard UV radiation, or to dehydration and the appearance of swelling of the nasal cavity with soft radiation.

4. The mask does not protect the respiratory organs of a person from dust and smoke.

5. The mask does not protect the environment from viruses that a person in a mask can emit while breathing through his mouth.

The objective of the utility model is to create a filter mask with a bactericidal emitter, which can be widely used as an individual protection against various infections transmitted by liquid droplet transmission, including various forms of flu.

The problem is achieved due to the fact that in the well-known individual filter mask with bactericidal treatment of air on radiating semiconductor elements, consisting of LEDs, means for their fastening, power supply unit and electrical circuit, according to a utility model, the mask contains a housing made of rubber or the plastic covering the mouth and nose of a person and the gripping chin and having a free volume near the mouth and nose, the body in the front face has a round hole made in de thin-walled cylindrical tube in which is inserted an annular board with LEDs, the luminous flux which is directed inwardly toward the opening, on the outside of the cylindrical tube is provided with a thread, which is screwed onto the second cylindrical tube, wherein the inner space filled with filter substances, closing the inlet opening.

In a technical solution, LEDs emitting in the range of 620-680 nm and 820-890 nm are introduced into the bactericidal emitter.

In a variant of the technical solution, the mask is equipped with a valve with an electrical contact that is activated by inhalation and exhalation, and each time it is triggered, including LEDs.

In an embodiment of the technical solution, the electric circuit is equipped with a pulsed multi-channel switch, including all light devices at the same time.

In an embodiment of the technical solution, the electrical circuit is equipped with a pulsed multi-channel switch, each of the contacts of which includes a particular type of LEDs.

In a variant of the technical solution, the mask is equipped with a valve that freely exposes the exposed air when exhaling

The body of the mask, made of rubber or plastic covering the mouth and nose of a person and capturing the chin and having a free volume near the mouth and nose, makes it possible to let all the air entering the respiratory system through the mask.

The use of a thin-walled cylindrical pipe inserted into the hole in the front of the mask, into which a ring board with LEDs is inserted, the light flux of which is directed inward, towards the hole, and the presence of a cylindrical thread pipe on which the second cylindrical pipe is screwed, the inner space of which is filled filtering substances that cover the inlet, allows you to filter and disinfect the entire volume of air entering the respiratory organs. In addition, due to bactericidal radiation, the filter density can be reduced, which will facilitate breathing.

The presence of a valve that works by inhaling and exhaling, and including LEDs, helps to reduce energy consumption and increases the life of LEDs and power supply elements.

The use of a pulse switch, including all the LEDs at the same time, increases the disinfecting effect of the mask and reduces energy consumption.

The use of a pulse switch that includes each of the installed types of LEDs individually also helps to increase both the disinfecting effect of the mask and reduce energy consumption.

The selected range of additional LEDs emitting in the range of 620-680 nm and 820-890 nm is optimal for disinfection.

The presence of a valve freely letting air out when exhaling allows the user to breathe more freely and helps to remove moisture that accumulates inside the mask body.

The claimed device is illustrated by 4 figures.

Figure 1 shows a mask when viewed from the side.

Figure 2 shows a fragment of a mask with a ring arrangement of LEDs.

Figure 3 presents the circuit diagram of the inclusion of LEDs.

Figure 4 shows a circuit diagram in which the LEDs are equipped with a pulse switch.

An individual filtering mask with bactericidal air treatment on emitting semiconductor elements is arranged as follows.

The mask contains a housing 1 (figure 1, 2) made of rubber or plastic. Along the perimeter, the body fits snugly to face 2 and closes the mouth and nose and covers the chin. Near the mouth and nose, the mask body has a free volume 3. The body in the front face has a round hole made in the form of a short thin-walled cylindrical pipe 4. An annular board 5 (figure 2) with LEDs 6 is inserted tightly to its inner walls. emitting bactericidal light fluxes. The board can be attached to the walls of the pipe, for example with glue. The light fluxes of the LEDs 6 are directed towards each other, i.e. inside, the annular plate and penetrate the air entering the mask body 1 .. The outer surface of the cylindrical pipe 4 is provided with a thread (not shown in FIG.), onto which a tubular case 7 is screwed, the inner space of which is filled with filter material 8 that covers the inlet of the thin-walled cylindrical 4 pipes. Filtering materials may include cotton wool, felt, gauze (several layers of gauze bandage), filter paper, activated carbon used in insulating gas masks. Moreover, such materials as gauze, felt, cotton, etc. can be repeatedly sanitized and reused, which significantly reduces the cost of operating this device. The mask is attached using an elastic belt 9, with a fastener made in the form of a buckle (not shown in Fig.). On the side, on the belt 9, on an inelastic platform (not shown in FIG.), A power supply unit 10 is installed, which feeds the electric circuit, which can be used as a rechargeable battery or replaceable batteries. The power supply has a switch 11, which includes LEDs. Power to the LEDs is supplied via hanging wires 12.

In a variant of the technical solution, light emitting diodes emitting in the range of 620-680 nm and 820-890 nm are introduced into the source of bactericidal radiation.

In a variant of the technical solution, the mask is equipped with a valve 13 that freely lets air out when exhaling. The valve can be located in the chin area, as shown in Fig. 1, and from the side. In the latest version of such valves, there may be two located on two sides.

In a variant of the technical solution, the mask is equipped with a flexible valve 14, made in the form of a petal, with a touch contact, including LEDs each time you inhale and exhale.

The electrical circuit (figure 3) consists of 6 'LEDs with a UV radiation spectrum, 6' 'LEDs emitting in the range of 620-680 nm, and 6' 'LEDs emitting in the range of 820-890 nm. Depending on the power and supply voltage, the LEDs can be connected in series or in parallel or in a mixed circuit. Limiting resistances 15 can also be introduced into the power supply circuit of the LEDs 15. The switch 11 and the touch valve contact 16 in the power supply circuit of the LEDs 6 are connected in series.

In an embodiment of the technical solution, the electric circuit is equipped with a pulsed multi-channel switch 17 (Fig. 4), inserted into the power supply circuit of the LEDs, and simultaneously including all light devices. The pulse switch can be switched on simultaneously with switch 11.

In an embodiment of the technical solution, each of the established types of LEDs 6 (6 ', 6' ', 6' '') is equipped with an individual pulse switch, which is part of the multi-channel switch 17.

An individual filtering mask with bactericidal treatment of air on radiating semiconductor elements acts as follows. After installing the pencil case 7 (figure 1) with filter material 8, mask 1 is worn on the face. The switch 11 supplies power to the LEDs 6. When air passes through the filter 8, the air is cleaned of dirt and dust. If the filter material is impregnated with any bactericidal composition, then the filter partially disinfects the air entering through the filter. Further, the air passes through the zone illuminated by LEDs 6, where it is disinfected and enters the lungs already completely devoid of any living bacteria or viruses.

The specified mask in the presence of a valve 13, freely letting air out when exhaling, can be used by both a healthy and sick person in an “aggressive” environment (in rooms infected with various viruses, bacteria, in dusty rooms at work). In this case, both air entering the mask and exhaled are irradiated. This is especially important in small enclosed spaces in which healthy people are present or should be present (hospital wards, residential, office premises), where the likelihood of infection increases many times. Also, this mask can be used for medicinal purposes in the treatment of various kinds of acute respiratory diseases, flu, tonsillitis, etc., caused by viruses, bacteria.

The use of red and infrared LEDs emitting in the 620–680 nm and 820–890 nm ranges as a radiation source makes it possible to increase the disinfecting properties of the mask. At the same time, LEDs with different emission spectra do not just complement each other, but provide a cumulative effect, in which the destructive effect of light on microorganisms and viruses increases sharply ..

Depending on environmental conditions, the mask can be used in different versions.

For example, in the absence of dust, case 7 can be omitted. At the same time, breathing is greatly facilitated, humidity inside the mask body decreases.

In the absence of bacteriological or viral danger, LEDs 6 can be omitted. In this case, the mask protects mainly from dust and smoke.

If the mask has a valve 14, with a valve pin 16 that turns on the LEDs during inspiration - exhalation, this helps to reduce energy consumption. In addition, transients that occur when changes in light flux can more effectively affect microorganisms, thereby increasing the disinfecting properties of the mask.

The use of a pulsed multi-channel switch 17, including a pulse and simultaneously all the light devices, increases the disinfecting effect of the mask and reduces power consumption.

The use of a pulsed multi-channel switch 17, including each of the installed types of LEDs individually, also helps to increase the disinfecting effect of the mask, as well as reduce energy consumption.

The proposed mask can be widely used for air disinfection for various consumer groups from medical workers to ordinary people. She easily removes and dresses. The mask can be used in various rooms, at home and at work, in medical institutions, in the salons of various vehicles, etc.

The technical and economic advantages of the proposed individual filter mask with bactericidal air treatment on radiating semiconductor elements are as follows:

1. Protection is provided, both the mask owner and the environment from various germs and viruses.

2. The mask is also suitable for fast walking or active load, even if a person breathes through his mouth.

3. The use of the mask is safe and cannot lead to damage to the mucous membrane.

4. The mask protects a person from dust and smoke.

5. The mask protects the environment from viruses that a person in the mask can emit.
