Description

The invention relates to a rescue service, in particular applicable to the operation of gas rescuers.

Today, a separate safety helmet is used to protect gas rescuers (

head / cre_HPS_6200.jsp), consisting of a body that covers the head, and a full-face mask with a pulmonary machine, connected to the air breathing apparatus (http://www.draeger.ru/RU/ru/products/personal_protection/masks/full_face/ cre_fps_7000.isp), including panoramic glass, an obturator, a valve box with an exhalation valve into the atmosphere, a suction cup with two inspiratory valves, or a full-face mask connected to an oxygen-insulating device (respirator) (http://www.draeger.ru/media/ 10/02/44/10024406 / pss_bg4_plus_pi_9044832_en.pdf), including panoramic glass, a shutter, a valve box with inspiration and expiration valves, with of the connections with the oxygen-insulating apparatus podmasochnik with two inspiratory valves.

The disadvantage of this design is that when working in difficult conditions (for example, in narrow aisles, in places where there are technological pipelines, in places where various structures collapse), a full-face mask with a pulmonary device are vulnerable parts of the structure that are easily damaged. Hoses supplying air to the lung machine and hoses supplying and discharging the respiratory gas mixture from oxygen respirators are also vulnerable. A full-face mask and a pulmonary machine can be severely damaged as a result of sharp volley emissions of aggressive media or spills with aggressive media.

At the moment, protective suits are used to solve this problem, for example, Trelleborg TRELLECEM SUPER, type TE (http://www.vostok.spb.ru/catalog6/models74/details3685.php), the upper part of the jumpsuit includes panoramic glass.

The disadvantages of such a protective suit is that its use dramatically reduces the visibility and maneuverability of the lifeguard.

During complex emergency operations at various hazardous production facilities (mines, chemical plants), there is a need for various specialized specialists (non-rescuers) to be present at the work site inside the danger zone, which is dangerous for their life, because they are not trained for rescue and repair work in such conditions. The need for the presence of narrow specialists at the scene of the accident may exclude the use of full-fledged audio and video communications by rescuers.

Currently, a radio signal is used to connect rescuers with the headquarters, transmitting an analog or digital (sound) signal that supports only a low data transfer rate, which does not allow specialists outside the emergency zone to fully assess the situation. For example, the Motorola GP640 VHF portable radio station is used (http://www.radiopole.ru/motorola/motorola_portable/gp640.php).

It can be equipped with a headset consisting of a microphone and an earphone, which can be mounted in a helmet or fixed on the head (http://rs01.ru/catalog.php?id=58).

The disadvantages of this communication system are: 1) communication works only in receive mode or only in transmission mode, it cannot work in telephone mode; 2) this radio station and the like cannot provide video transmission; 3) large overall dimensions of the radio station.

The prototype of the claimed invention is a full-face mask of the German company Drager model Panorama Nova P (Instructions for use and maintenance - Panorama Nova P, P.79). The full-face mask consists of a button, a distribution valve, an internal mask, a porthole, a porthole clamp, a central belt, head belts, a shutter, a mask body, a clamp, a protective cover for the exhaust valve, and a mask connector. Full-face mask is designed to protect the face and eyes in aggressive environments. It is used with breathing apparatus with compressed air or with respiratory apparatus with air supply with overpressure through the hose. A pulmonary machine is attached to the valve box of the mask.

The disadvantages of this design are as follows:

1) When working in difficult conditions (for example, in narrow aisles, places where there are technological pipelines, in places where various structures collapse), a full-face mask with a lung machine are vulnerable parts of the structure that are easily damaged. Hoses supplying air to the lung machine and hoses supplying and discharging the respiratory gas mixture from oxygen respirators are also vulnerable. The medium-pressure hose that connects the lung machine to the gearbox interferes with the work of the rescuers.

2) A full-face mask and a pulmonary machine can be severely damaged as a result of sharp volley emissions of aggressive media or spills with their aggressive media.

The technical result of the claimed invention is to increase the safety of the gas rescuer, ensuring its good maneuverability and full communication with the headquarters and other rescuers.

The specified technical result is achieved in that the protective helmet, which includes a full-face mask, is attached to the valve box of a pulmonary machine, from which there is a medium-pressure hose connecting to the quick-disconnect device on the device, according to the invention, the protective helmet is divided into two parts moving relative to each other along guides and connected with the help of special quick-release locks, around the full-face mask and pulmonary machine an external protective casing is created, turning into protective th helmet, a medium-pressure hose is placed in an external protective casing in the lower part of the protective helmet, a tactical flashlight is installed in front of the protective helmet with the ability to turn it off without removing the protective helmet, a video camera with the ability to transmit a video signal in real time.

The design is illustrated in the drawing, which shows a General view of the protective helmet.

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

The protective helmet consists of two parts: front 1 and rear 2, interconnected by quick-release locks 3. The front part 1 of the protective helmet is an external protective casing covering the lung machine and full-face mask. The rear part 2 of the protective helmet is an external protective casing covering the head. Inside the external protective casing covering the head, there is a soft substrate for shock absorption and wearing comfort (shock-absorbing layer 4 of a protective helmet); in front of the protective helmet 1 there is a full-face mask fixed in a protective fiberglass casing, and a pulmonary machine.

The full-face mask consists of panoramic glass 5, a shutter 6, a button 7 for disconnecting the pulmonary automaton from the full-face mask, inspiratory valve 8, dual inspiratory valve 9, suction pad 10, communication membrane 11, exhalation valve seat 12, and exhalation valve 13.

A medium-pressure hose 14 is connected to the lung machine, which is laid in an external protective casing on the right side of the protective helmet.

The structure of the structure also includes: the case of the pulmonary automatic device 15, the button for turning off the overpressure 16, the chamber of the pulmonary automatic device 17, in which the vacuum is created and air is supplied from the cylinder, the place of connector 18 of the front 1 and rear 2 parts of the protective helmet.

The front 1 and rear 2 parts of the protective helmet are fastened to 5 guides, ensuring the separation of the protective helmet. They are equipped with quick-release locks 3 for snapping a protective helmet on the head. Guide and quick locks 3 are located on the front part 1 of the protective helmet. The protective casing over the pulmonary machine and full-face mask is made collapsible. The design of the protective casing provides for the possibility of turning on and off the overpressure in the under-mask space using the overpressure off button 16, and it also provides for the possibility of maintenance of the pulmonary machine and valve box of the full-face mask. The hose leading the air to the lung machine is laid in a special pocket of the protective helmet on the left side and is brought out from the back of the 2 protective helmet.

In the front part 1 of the protective helmet, outside the lifeguard's field of vision, a tactical flashlight, a video camera, and electronic equipment for transmitting a signal from a video camera are built in.

The device operates as follows. The hose exiting the pulmonary machine is connected to a quick-disconnect connection on the air breathing apparatus. The lifeguard puts a safety helmet over his head and fastens the fastening belt under his chin. The lifeguard pushes the front part 1 of the safety helmet to the rear 2 and snaps it into the quick-release locks 3, ensuring a tight seal of the full-face mask obturator 6 to the face of the rescuer. The movement of air in the mask space is shown in the drawing. Before removing the protective helmet, the rescuer turns off the overpressure in the under-mask space by pressing the button 16 located in front of the external protective casing. On both sides of the protective helmet, the rescuer presses the buttons of the quick release locks 3, and the front half of the protective helmet, under the action of the springs, moves forward along the guides. The lifeguard unfastens the belt, removes the protective helmet from the head and unfastens it from the quick-connect connection of the air breathing apparatus.

Video calling is based on real-time Wi-Fi technology. A video camera mounted in a protective helmet transmits video and audio information to the headquarters or other rescuers. In the case when the rescuer goes beyond the communication range from the base station, he installs compact repeaters with an autonomous power supply in the course of its movement.

Such a constructive implementation of a protective helmet makes it possible to ensure full protection of the gas rescuer, increase the efficiency of emergency rescue operations due to the greater maneuverability of the rescuer, reduce the cost of operating gas rescue equipment due to the higher protection of the mask and the lung machine of the breathing apparatus, as well as provide video and audio communication between rescuers and headquarters and between a group of rescuers. The use of such a connection is possible in closed areas.
