Description

The utility model relates to personal protective equipment, in particular to the field of weapons and equipment, to the development of protective uniforms.

In conditions of warfare, including the use of weapons of mass destruction (WMD) to maintain the combat effectiveness of personnel, one of the main elements of a combat individual’s personal equipment will be personal protective equipment for skin and respiratory organs.

Currently, the PMK series general-purpose gas masks are available as the main means of personal respiratory protection (RPE) on supply in the Armed Forces of the Russian Federation (RF Armed Forces). The design of these gas masks is a mask and a headgear with straps [1].

The specifics of combat activity necessitate the functioning of soldiers mainly outside of shelters and military equipment, when he needs reliable protection of equipment from a wide range of combat threats. The use of PPE is primary in protecting against WMD, other types of weapons with high-intensity thermal and optical damaging factors, as well as providing head protection from pistol bullets, fragments and mechanical damage using personal protective equipment (NIB) [2]. Isolation of a person from the environment by modern PPE in a complete set of objects of the defense system and other systems of the combat equipment kit is accompanied by:

- limiting the heat exchange of the body with the external environment, leading to overheating up to thermal shock;

- a decrease in visual, auditory, organoleptic and tactile sensitivity;

an increase in the load on the musculoskeletal system, fettering movements, which ultimately leads to a decrease in combat effectiveness from 10% to 100%.

The emergence of new military threats leads to the need to expand the number of defense elements in the military equipment, as well as to identify ways to achieve the comprehensiveness and universality of their protective properties.

A device has been developed that combines a breathing mask and a helmet to protect the respiratory organs and head from chemicals [3]. A device for protecting the respiratory system and head includes a breathing mask, a filter-absorbing system (FPS) and a helmet. The helmet in the frontal part has a mount in the form of a molded recess for engaging the metal bracket of the eyeglass mount holder, and in the ear there are two fixation nodes with adjustable elastic clips, through which a breathing mask is connected. In the occipital part of the helmet there is a FPS bayonet connection unit, an air duct is fixed under the helmet, which is connected to the breathing mask adapter by the front end via a crimp elastic coupling, and connected to the FPS through the bayonet mount [3].

A respiratory protection device has been developed comprising an air regeneration system with a regenerative product and a respiratory isolation unit in the form of a cap and / or mask. It is intended for emergency use. A device for respiratory protection in an emergency contains a protective cap and a regenerative cartridge with a fan. The cap is made of flexible gas-tight material and equipped with a neck seal in the form of a ring of elastic material. The technical result of the utility model is to ensure comfortable breathing when using additional PPE in the form of a helmet with a visor [4].

A device for respiratory protection has been developed that contains a cap with a neck seal made of a gas-tight heat-resistant flexible material and equipped with a transparent section in front of it [5].

An air regeneration system is placed in the inner cavity of the cap in the form of a package of plates of a regenerative product enclosed in a porous shell. The shell is placed in a shell attached to the wall of the hood. An air flow inducer is attached to the end of the shell, the drive of which is connected to the power source through a switch. EFFECT: reduced weight and dimensions of the device and the possibility of operation at high loads [5].

A protective helmet has been developed, including a full-face mask with a valve box [6]. A lung machine is attached to the valve box, from which there is a medium pressure hose. The hose is connected to the quick disconnect device on the device. The technical result of the utility model is to increase the safety of the gas rescuer, ensuring its good maneuverability and full communication with the headquarters and other rescuers.

A protective tool designed for the environmental protection of humans and technological processes was also developed. The protective device contains a device directly designed to change the properties of the air flow, devices for its intake and bringing to the place of consumption. The main design feature of an individual protective equipment is the presence of a device designed to directly bring the air flow (past the frame cavity) to the respiratory organs of the user, i.e. masks or, for example, a mouthpiece [7].

The closest analogue of the utility model in terms of all the features is a protective device related to the rescue service, in particular applicable to the operation of gas rescuers. The protective helmet includes a full-face mask and a lung machine, a flashlight and a video camera, consisting of two separate parts, connected using quick-release locks. Around the full-face mask, an external protective casing is created, turning into a protective helmet, this design is removable, to reduce the overall dimensions of the helmet, the lung machine is mounted in a bayonet connection on the left side of the external body of the main helmet and is closed by a removable protective casing, a fitting is installed in the back of the external body of the main helmet for connecting a quick-release device of an air breathing apparatus. The technical result of the utility model is to increase the safety of the lifeguard, the ease of use of the helmet, the versatility of the helmet.

The helmet design uses a full-face mask and a lung machine. A full-face mask connected to a pulmonary machine is hermetically integrated into the construction of a protective helmet [8].

The main fundamental disadvantages of a safety helmet are:

- the use of a lung machine and cylinders with compressed air;

- Lack of comprehensive protection against RBC for damaging factors;

- non-optimal compatibility of respiratory protection with promising helmets, optical instruments, communication headsets and other elements of military equipment;

- insufficient level of protection of the respiratory system and head.

Having considered the above means of protection, we can conclude that the system of comprehensive protection of the respiratory system and the head as a whole should be autonomous, interfaced with the design of the combat helmet and other elements of the military personal equipment kit.

The technical task of the proposed utility model is to improve the overall dimensions and reduce the breathing resistance of military personnel in carrying out missions for their intended purpose in the context of the use of weapons of mass destruction (WMD).

The technical result to improve the overall dimensions and reduce the breathing resistance of military personnel in the proposed solution is achieved by using two low-profile filtering elements with two air flow inducers (micro-electric fans) on the sides of the front of the helmet, the drive of which is connected to the power source through a switch.

A device for protecting the respiratory system and the head with a gas mask-armor helmet, consisting of the following main elements:

fabric-polymer case (helmet is the main load-bearing element of the device); protective glass (visor); intercom; suction pad; two exhalation valves combined into a physiological chamber; power element with switch and charger; two low-profile filtering and absorbing elements (PFE); devices for safe fluid intake; forced air devices (micro-electric fans); abturator pelerines with a sealing device (neck seal with two overpressure valves); slats for installing a night vision device, tactical flashlight; chin strap; sub-bullet device; knitted hydrophobic cover.

In FIG. 1 shows a device for protecting the respiratory system and the head with a gas mask-armor helmet, front view, side view and bottom view.

The body of the device is the main supporting structural element. The body of the helmet is made of fabric-polymer material - Kevlar, which provides increased protection of the head from pistol bullets, fragments and mechanical damage (Fig. 1, item 1).

A polycarbonate visor mounted on an armored helmet, characterized by increased strength, hermetically adjacent to the body (when closed), as well as a high degree of eye protection from laser radiation and light flashes (Fig. 1, item 2).

The protective glass (visor) of the gas mask is made in the form of a single monoblock, which reduces the load on the eyes of the military man, and also maximizes his field of vision. In addition, the protective glass has increased mechanical strength and an improved system of protection against sunlight.

The intercom is designed to improve the quality of voice transmission when using a security tool. The intercom is made in the form of a non-separable capsule mounted during assembly, consisting of a body, a rubber ring, a membrane, a support ring, a flange and a cover (Fig. 1, item 3).

A microphone is installed inside the front part (Fig. 1, item 4), which allows for improved communication using a special insulated adapter that connects from the outside.

The suction cup is designed to reduce fogging and freezing of the protective glass (Fig. 1, item 5). It is made in the form of a rubber half mask with two inspiration valves. Excludes hit of exhaled air on a visor.

The physiological chamber of the suction cup is designed to distribute the flows of inhaled and exhaled air. In the physiological chamber there are two exhalation valves - the primary and secondary (Fig. 1, pos. 6). The significance of the physiological chamber is that in it there is a dilution of the concentration of external infected air sucked through the first valve. Thanks to dilution

the concentration of harmful impurities penetrating through the second valve decreases.

The helmet is connected via connectors to the battery (Fig. 1, item 7), which feeds the fans, and they, in turn, through the lateral part of the mask (through the PFE) pumps air into the nose bowl so that its inflow during inhalation is constant . A connector for a charger is provided for charging the power element (FIG. 1, item 19).

Front part providing a high level of comfort and protection. On the front side there are two low-profile filter elements located on the sides of the front mask (Fig. 1, item 8).

Double low-profile PPEs have significantly reduced breathing resistance and improved gas mask mass distribution.

FEP can be replaced by a military man without violating the tightness of the shutter, which is achieved due to the self-sealing compound.

The filtering elements of the device are made of flexible material (plastic), inside of which there is an aerosol filter (Fig. 2 pos. 22), carbon fabric (Fig. 2 pos. 21), the lower cover of the inhalation valve filter housing with a brace (Fig. 2 pos. 20) and the top cover of the filter housing (Fig. 2, item 23). On the inside of the helmet, micro-electric fans are connected, which are switched on using the switch located on the right side of the helmet (Fig. 1, pos. 15).

Low-profile filtering elements are equipped with carbon cloth, which is a non-woven carbon fiber material (felt) with a final heat treatment temperature of 850-900 ° C, which allows to provide a high level of protection against toxic substances, toxic and radioactive dust.

The choice of this material is due to its wide possibilities of using various types of artificial and synthetic fibers and waste products as raw materials, as well as various methods of forming non-woven material, which allows one to obtain an adsorbent, active non-woven material with different thickness and length of the fabric, surface density and textile structure.

The protective equipment is equipped with a special device for safe fluid intake (Fig. 1, item 9). It ensures its compatibility not only with standard flasks. This constructive solution significantly increased the safety of its use during operation in the conditions of RCB infection.

The liquid intake system is designed to receive water and liquid food in an infected atmosphere. It consists of a mouthpiece, fitting, rubber tube, nipple, flask cap with valve and cork. The flask lid with the valve is mounted on the flask instead of the usual lid.

Micro-electric fans are designed to force the supply of clean air and create excessive pressure in the submask space (Fig. 1, item 10). On the inner surface

- high wear resistance and practicality;

- high comfort when worn for 24 hours in any climatic zones (the values of pain sensitivity are reduced in comparison with the use of a filtering gas mask in the "combat" position).

Thus, the most important design solutions implemented in the new protective device are:

- the use of non-woven carbon fiber materials to provide comprehensive protection against radioactive dust, OV, BA, industrial toxic chemicals;

- modularity, providing quick replacement of failed filters in less than 18 s;

- low mass of the device (reduced local mechanical impact on the head);

- increase in the area of the protective helmet in the lower part of the soldier’s head through the use of a fabric-polymer case made of Kevlar (the protective properties of the soldier’s head from pistol bullets, fragments and mechanical damage have been increased).
