Description

The development relates to means of protecting a person from exposure to hazardous factors during rescue (evacuation) as a result of a fire or accident at various facilities.

There are risks of fires in maternity and child care facilities. Currently, equipment for fire-rescue units and child care facilities for saving newborns from a non-breathing environment (VAT) with a low oxygen concentration is not provided, although there is such a need.

A rescue breathing device is known (RF №2124375, IPC АВВ 18/04, 01/10/1999), containing a protective mask made of soft, transparent, fire-resistant material with a soft elastic seal around the neck opening, and a device for feeding under the mask of the respiratory mixture, according to the invention is equipped with a separation gear to allow the breathing mixture to be breathed freely from the respiratory mixture supply device, which is an autonomous balloon or common line, and the neck is sealed It is leaky. In this case, the supply of the respiratory mixture into the undermask for breathing and the removal of exhaled gases is carried out by blowing it through the undermask, and the removal of exhaled gases by etching through a soft, elastic, leaky neck seal. The supply of the respiratory mixture can be carried out with adjustable pressure in comparison with the external pressure outside the mask.

With sufficient reliability and simplicity of the device, it cannot be used for evacuation of newborns due to the limited dimensions of the protective mask.

There is also known a device for protecting the respiratory system and skin (RF patent No. 2142299, IPC АВВ 31/00, 12/10/1999), including a rigid frame made of rods, a shell with a hole and a transparent window on the front wall, niches located on the sides of the shell , and an air regeneration system in the form of a diffusion-sorbing element. The device is equipped with an elastic retainer located on the wrong surface of the back wall of the shell, and two mittens, one of which is placed on the front wall of the shell and the other on one of the side walls, while the rigid frame is inserted into the head portion of the shell, and the hole is made on it back end.

Some of the disadvantages of the device include the fact that it must be kept assembled in a child’s room in a dust-proof condition, placed on the danger signal of a swaddled child placed in the cavity of the device and bent its open end, however long-term storage of the device is often inconvenient, especially when used in hospitals and maternity hospitals, and increases the duration of the preparation of the child for transportation; the main disadvantage of the known device is its unsuitability for use at a reduced oxygen content in the ambient air, which makes it limited suitable for saving a child in case of fire and gas emissions.

There is also known a device for protecting the respiratory organs of children (RF patent No. 2329076, IPC АВВ 31/00, 07/20/2008), which can be used when transporting infants in a bed for a newborn in an unsuitable atmosphere for breathing. A device for protecting the respiratory organs of children includes a gas-tight shell equipped with an overpressure valve with a sealing unit and an air regeneration system. A gas-tight shell is installed on the upper cut of the couvez. The air regeneration system is installed on the inner surface of the gas-tight shell and is made in the form of a flow rate secured to a gas-tight shell, equipped with a power supply unit, a sleeve with a regenerative product fixed in it. The regenerative product is made in the form of profiled plates of potassium superoxide deposited on a substrate. This device is taken as a prototype.

However, the complexity of the design and significant weight due to the built-in air regeneration system, the need for constant monitoring of the battery charge level, as well as the occurrence of zones with insufficient oxygen concentration for breathing, limits the possibility of using the device.

The objective of the utility model is to create a more voluminous folding device without batteries to save (evacuate) one or two newborn swaddled children in the event of unfavorable breathing conditions (fire, accident, etc.) using one or a minimum of lifeguards for easy storage devices and speed of deployment.

The problem is solved in that the proposed universal rescue device (USU) is made of lightweight non-combustible material in the form of a folding container with a volume of 250-300 l with folding spacers weighing no more than 5 kg with a can of compressed air with a pressure indicator providing constant air exchange of the internal space during 18-20 minutes, and can be stored folded and easily transformed into a working position that can be closed (fastened) with an extension cord at the bottom, while the case is made of lightweight heat-resistant material in the form of a foldable container with a viewing window and an inner sleeve on the one side (right), and on the sides arranged folding struts. For carrying the container, fixed straps of different lengths are used, located on all 4 sides of the container body, and inside the body in the upper front and lower parts there are folding polyurethane foam plates to protect the evacuated and add rigidity to the structure. The control system is equipped with a cylinder of compressed air with a volume of at least 3 l (pressure 26-30 MPa), equipped with a gearbox and a quick disconnect coupling (BRS). In the side of the container there is a hose with a quick disconnect bushing (BRS) for connecting to the gearbox clutch, as well as with the possibility of connecting (the air in the container balloon has run out) to an external source of compressed air (lifeguard breathing apparatus). On the body of the control valve there is a valve supporting an overpressure in the internal cavity of the container of not more than 600 Pa. Additionally, when folded, the USU is a shield and can be used to protect against heat flow or as a stretcher for carrying objects and children in case of injuries.

In FIG. 1 shows an embodiment of the USU in the form of a portable folding container, designed for the evacuation of newborns. The container can be transported by one - two rescuers or staff of the institution. The approximate overall dimensions (LxWxD) of the container are 1120 × 600 × 430 mm.

Case 1 of FIG. 1 is made of light heat-resistant material. An inspection window 2 is located in the upper part of the front wall of the casing. To give the functional design of the operation of the control system, the folding spacers are located on two sides. The air is evacuated to the control unit from the cylinder, which is located in compartment 5 inside the container in its lower part, through a hose 4 which is connected by means of a plug-type quick coupler to a reducer clutch or a hose of a fire-rescuer compressed air breathing apparatus (DASV), or from an autonomous cylinder equipped with a reducer m and clutch couplings. In the sleeve of the hose 4 there is a calibration hole that provides a constant air supply to the USU in the amount of 45-50 l / min. In the event of a hose rupture, an alternative option is provided for supplying air to the control system via junction box 6. For this, a plug is unscrewed from the junction box, the DASV pulmonary gun is inserted into the hole and at the press of a button air is supplied in the amount of at least 70 l / min. into the internal cavity of the control system. Hose 4 and junction box 6 are fixed on the body in the place closest to the evacuees' heads. A sleeve 7 is placed on the right side of the USU case, which is used to carry out actions with newborns without opening the container. To create a tightness inside the control unit there is a sealing unit 8 - a tourniquet with a clamp is passed along the perimeter of the lower part of the housing. The container is carried using straps 9 of different lengths, located on all sides of the container. Excess air generated during the evacuation process will escape into the atmosphere through the excess valve 10, as well as through leaks of the sealing unit 8. The estimated pressure inside the control unit is not more than 600 Pa. Inside the case in the upper, front and lower parts there are polyurethane foams 11 to protect the evacuated and to give rigidity to the structure.

The use of the control unit is possible not only by the fire and rescue units, but also by the personnel of the maternity homes and orphanages, provided that the set of the control unit will include a 3-liter compressed air cylinder with a pressure of 30 MPa, equipped with a gearbox and a quick coupling.

To carry out evacuation via VAT, it is necessary to install spacers 3, the hose sleeve 4 is connected to the cylinder gear box, the cylinder valve opens, which is located in the compartment 5 inside the housing 1, the newborns (newborn) are placed in a container, the sealing unit is blocked (tightened). Using the straps 9, the container with the children is transported to a safe place. In this case, the staff of the institution should be in personal protective equipment for respiratory organs (self-rescuers, gas masks). In the event of an emergency (if there is no air left in the cylinder of the control unit), the hose sleeve 4 is connected to the clutch of the gearbox of the self-contained cylinder or to the fire-rescue fire safety device of FIG. 2.

Benefits:

in the folded compact state it can be used as a shield that protects against heat flow, and also as a stretcher for carrying objects and children in case of injuries;

constant overpressure is maintained, which prevents VAT from entering the internal cavity of the control system;

protection against most dangerous and related fire factors;
