An individual means for protecting children contains: a protective hood; ammunition for wearing; filtering and absorbing boxes (2 or 3 pcs.); connecting tubes; a microelectric fan with a power supply unit (MEW), which provides the supply of purified air to the sub-hood space in the amount of 80 and 120 l / min. On the ammunition there is an electric fan, a power source, filter-absorbing boxes.

Description

The utility model relates to personal respiratory protection from toxic substances (OV), radioactive dust (RP), biological aerosols (BA), accidentally chemically hazardous substances (AHOV - acid gases and vapors, organic vapors, ammonia, sulfur dioxide, nitrogen oxides etc.), radionuclides of iodine and its organic compounds and aerosols.

Known respiratory protection according to patent No. 22417175 (publ. 02.26.1992), comprising: an elastic hood covering a person’s head with a neck seal consisting of an elastic band and an elastic cord or elastic septum; a filter, for example, for protection against OV, RP and BA and a fan attached to the hood shell; a fan power supply located in a pocket on the back of the hood or in the case. Headphones may be included to protect your ears from fan noise.

The disadvantages of the known respiratory protection are:

- the complexity of operation in connection with the placement of a fan with a filter and current sources on a thin elastic shell of the hood, while the mass of components will put pressure on the person’s head, creating inconvenience during operation. In addition, the presence of a fan and current sources inside the hood impairs its protective and operational performance.

The design of the CH 14 protective hood, advertised by Neoterik Health Technologies.Yng (USA), is devoid of these disadvantages.

Respiratory protection CH-14 consists of a vest made of synthetic fabric, to which a cap made of polymer plastic is sewn. A headband is fixed at the top of the cap. Inside the cap in the front part, a viewing window of frame polymer material is fixed. At the rear of the hood there is an air overpressure valve. In the upper part of the vest there is a non-stretching tape designed to regulate the size of the vest in the neck. There is a special clip to secure the braid. On the bottom of the vest is fixed a wide, non-stretching tape with a detachable buckle to fix the vest on the body. In the front part of the vest, a connecting pipe for air supply is mounted in the center. Two pockets are sewn at the bottom of the front of the vest: a fan is placed in one pocket, and a water flask in the other. A connecting pipe is attached to the fan housing for supplying air to the hood, and there is also a threaded connection for attaching a filter-absorbing box (FPK). It is possible to complete the protective hood with filtering and absorbing boxes of various brands. The volume of air supplied to the hood is 70 l / min.

The disadvantage of the CH14 protective hood is that the design of the protective hood is not intended for use by children in a wide age range (from 7 to 17 years), and does not provide the possibility of regulating its size in a wide range, which prevents the use of a protective hood by users of different ages and complexions, also a disadvantage is the inconvenient, not meeting the safety requirements, the placement of the fan and filter-absorbing box (FPK) in the pockets of the vest.

The objective of the invention is the creation of a unified personal protective equipment for the face and respiratory system with forced air supply for younger and older students.

To achieve the specified technical result, an individual protective equipment comprising a protective hood with a panoramic window, an overpressure valve, an air duct-headrest, an electric fan, a power supply, a filter-absorbing system (collector and filter-absorbing boxes) and a connecting tube is equipped with a frame back with a waist and shoulder straps on which the electric fan, a power source, a filter-absorbing system are located.

Distinctive features of the proposed individual means for protecting children from the above known, closest to it, is that the electric fan, power supply, filter-absorbing boxes are placed on the ammunition, which is a frame back with waist and shoulder belts.

Due to the presence of these essential features, an individual product was obtained for children with a unified frame back suitable for use by various age groups of children.

Figure 1 shows an individual means for protecting children.

Figure 2 shows the duct-cap placed in the hood.

An individual means for protecting children (FIGS. 1, 2) contains a volume hood 1 made of lightweight protective material. The hood is equipped with a panoramic window 2, providing a panoramic view. An overpressure valve 3 is mounted on the front wall of the hood below the panoramic window in the region of the user's respiratory organs. At the bottom of the hood is a braid 4, which is looped 5. The braid 4 is provided with fixation elements through which the hood is sealed in the neck. Fixing the free end of the braid with the help of fixing elements on the braid and loops prevents the hood from being depressurized during the operation of the product. In the upper inner part of the hood is integrated duct-cap 6 (figure 3). The air duct-headgear serves to evenly distribute the purified air supplied to the hood, and also plays the role of a headguard that is adjustable in size, whose carcass, in turn, gives volume to the hood. The cleaned air is forcedly fed into the hood by a micro-electric fan (MEW) through a connecting tube 7. The micro-electric fan with a power supply unit (MEW) is designed to draw air through filter-absorbing boxes 8 and to force the cleaned air into the protective hood.

The MEV kit includes: air blower 9 in a casing fixed to ammunition; power supply 10 with a power on indicator light (green), a power indicator light indicator (red), a sound indicator of a power source discharge. The collector 11 is permanently attached to the ammunition and is designed for parallel connection of two or three filter-absorbing boxes 8. The connecting tube 12 is designed to connect the micro-fan blower to the collector. The 2nd (FIG. 1) or 3rd (FIG. 2) filter-absorbing boxes 8 (depending on the need for supplying purified air to the sub-hood space in a volume of 80 or 120 l / min) can be connected to the manifold 11.

The personal protective equipment contains ammunition for wearing, which is a frame back 13 with a soft insert facing the user, a waist belt 14 and two shoulder belts 15. The length of the belts on the ammunition is adjustable using buckles 16. The belt is fastened with a quick buckle-lock 17.

An individual protective equipment containing ammunition, on which an electric fan, a power supply, and filter-absorbing boxes are located, is convenient to use due to a simple fit and placement of cleaning and air supply devices behind the back.
