St. N 126020, A62B 17/00, 1960).

A disadvantage of the known protective ventilated pneumatic suit is the lack of sufficient isolation of the user by means of the designated suit from the environment and, as a result, its low reliability under conditions unsuitable for breathing.

Known pneumatic suit NBK-1, made of a single layer rubberized nylon fabric with a filler such as soot. The pneumosuit is made in the form of a combined thermogradient shell; a helmet combined with a shell; dynamic liquid cooling suit; electro-, pneumo-, hydro-communications; overpressure valve; blocks of flowing (water and gas) calorimetric devices. On the inner surface of the thermogradient sheath, flat ventilation hoses for supplying gas to various areas of the suit space are fixed. The suit's ventilation system provides breathing and removes metabolic heat, moisture, carbon dioxide and other anthropotoxins from the undersuit space. In the volume of the suit, temperature and pressure are maintained over a wide range. The weight of the whole set does not exceed 6 kg. (See the Reference book on labor protection in mechanical engineering. Prof. ON Rusak. Dr. Leningrad: “Mechanical Engineering” Leningrad Branch 1989, p. 311)

The disadvantage of the NBK-1 Pneumocostum is the lack of a sufficient number of excess air pressure relief valves and the absence of stitching connections, which contribute to greater product reliability due to their tight fastening to the bottom of the trousers.

A number of pneumatic suits of the LH line are known, which are hose insulating suits with the forced supply of clean air for breathing and ventilation of the suit space, and designed to completely isolate the body from the aggressive environment of the working area. The pneumatic suits of the LG line consist of two main parts: the protective shell and the ventilation system of the undersuit space, the protective shell of the pneumatic suit is a jumpsuit made of polyvinyl chloride plastic with a helmet welded to it, in front of the jumpsuit there is a hole through which the suit is entered and exited, overalls sleeves end with plastic rings or (as agreed with the customer) with rubber bands welded to the low sleeves; low trousers end with the same elastic bands or shoe covers welded to the trousers; in front of the helmet there is a welded to it (pneumatic suit LG-4) or a removable sight glass fixed to the helmet with two rubber rings welded to the edge of the viewing window (pneumatic suit LG-5); pneumatic suits LG-4 and LG-5 are made of polyvinyl chloride plastic, LG-U is made of rubberized material. The ventilation system for the undersuit space consists of a plastic fitting connecting the pneumatic suit with a hose, a soft duct through which air enters the helmet, waist air ducts that allow free air flow from the upper part of the pneumatic suit to the lower and visors openings in the trousers, through which the ventilation air leaves pneumosuit in the surrounding space. Due to overpressure in the undersuit space and constant ventilation of it with clean air, a high degree of isolation of the worker working from the external environment and the conditions necessary for gas, heat, and moisture exchange of the body with air in the suit space are provided at the same time (see Reference 0-1.RU) .

Three types are available:

- LG-4A - the sight glass is welded to the helmet, the trousers are low on elastic bands;

- LG-5A - the sight glass is removable, two ducts welded on the back, low trousers with elastic bands;

- LG-5B - the sight glass is removable, shoe covers are welded to the low trousers.

The pneumatic suit LG-5A (with a sleeve KSh 20-0.3-20000) without an intercom (see TU 696890-004-08625805-2011) is made in the form of an insulating suit, the protective shell of which consists of a jumpsuit with a helmet welded to it in which the sight glass is mounted removably, in front the jumpsuit is equipped with a hole for entering and leaving the suit; overalls sleeves end with rings, and the bottom of trousers with elastic bands;

Pneumatic suit LG-5B (with a sleeve KSh 20-0.3-20000) with an intercom (TU 696890-004-08625805-2011, TR TS 019/2011). It is an insulating suit, the protective shell of which consists of overalls with a helmet welded to it. In front of the jumpsuit there is a hole for entering and leaving the suit. Overalls sleeves terminate in rings.

A disadvantage of the known protective suits of this line is the short life of the products (3-6 months), manhole sealing by tucking, and the high cost of the product.

The closest in technical essence to the claimed object is a pneumatic suit LG-U, made of rubberized fabric made in the form of overalls with a stitched hood with panoramic glass in the front and a connector in the front for entering and leaving the suit; moreover, the overalls sleeves end with sleeve rings or rubber cuffs, which provide the necessary seal at the sleeve-glove joint, and the bottom of the trousers ends with stitched boot covers; the hood serves as direct protection of the respiratory system; the pneumatic suit is equipped with a ventilation system for the undersuit space and an emergency air supply system and is designed to protect skin from industrial hazards (vapors, aerosols, liquids and gases), which includes waist air ducts that provide ventilation for the undersuit space, petal step valves located at the bottom of the trousers and sleeves designed to relieve excess pressure created in the suit space. (See Technical Description and Instructions for Use. A4.05.000.TO, 1972, p. 11).

The disadvantage of the pneumatic suit LG-U is:

- a method of sealing a manhole by twisting increases rigidity in the abdomen of the user, which greatly complicates the ease of use of the pneumosuit;

- the difficulty of attaching the hose to the back of the user by overlapping the ties sealing the hole;

- ties that seal the manhole in this design are tied in front to a knot - “bow”, which is an unreliable sealing element;

- dragging the overalls with ties in the belt area necessitates the use of two soft ducts to supply air to the lower part of the user's body;

- insufficient number of air overpressure relief valves (4), contributing to a comfortable stay in the user's suit, can lead to the formation of stagnant zones;

- relief valves for excess air pressure flap step, not equipped with caps.

The objective of the utility model is to create a pneumosuit that will meet the higher requirements of reliability and ease of use.
