Description

The utility model relates to means of ensuring human life and can be used as a means of individual protection of a person in zero gravity during long-term work in outer space.

A device for maintaining orthostatic stability in zero gravity is known, in which an elastic element is used that plays the role of artificial gravity to create an adequate load on the musculoskeletal system. In this device, the elastic element is attached on one side to the support of the spacecraft and on the other side to the person, which allows reproducing short-term inertial-shock (directed along the longitudinal axis of the human body) loads (Authors. St. USSR N 256164, class A63B 23 / 00, 1976, publ. 07/05/1976, B. No. 25).

The disadvantage of this device is the short-term effect of the load on the musculoskeletal system of a person in zero gravity. When using such a device, the load is carried out only on a specific muscle group and requires an additional investment of time.

Known suit for work in zero gravity from a knitted fabric made of filaments of ordinary stretch and elastomeric filaments forming an elastic frame that provides a load on the musculoskeletal system of a person (RU, Russia, patent No. 2060913, microliter B64G 6/00, publ. . 05.27.96).

The reasons that impede the achievement of the required technical result is that such a suit carries out insufficient load on the muscles in the arms.

A known zero-gravity suit made of a knitted fabric consisting of ordinary tensile threads and elastomeric threads forming an elastic frame, the details of the suit in the chest and abdomen are made of tubular elastic knitwear, in the structure of which weft elastomeric threads are located between the loop arcs loops of elastic knitwear, and have linear dimensions 10-35% smaller than the corresponding sizes of parts of the human body. (RU, Russian patent No. 2116944, microliter B64G 6/00, publ. 10.08.98).

The reasons that impede the achievement of the required technical result is that such a suit does not exert pressure on the muscles in the arms.

Closest to the claimed utility model is a suit for work in a spaceship and an orbital station, which is made of elastic canvas, and the details of the suit, which provide a load on the musculoskeletal system of a person, are smaller than the size of parts of the human body. The suit consists of a jacket with a hood, pants, on which reinforcing strips of elastic material are placed, as well as a belt made with the possibility of tight connection of the jacket and pants in tension mode, as well as gloves. Moreover, as an elastic web, a polyurethane web is used. In addition, the suit is equipped with an automatic valve system configured to operate in constant and pulsating modes, with the inlet and outlet valves symmetrically located at the chest level, the inlet valve at the waist level, and the outlet valve at the hip level. (Patent of Ukraine No. 71838 U, m.cl. B64G 6/00, publ. 25.07.2012, B. No. 14).

The reasons that impede the achievement of the required technical result is that such a suit is not effective enough, because it does not provide a sufficient load during the work of a person with his prolonged stay in a state of weightlessness.

A study of the effects of a person in space showed that the absence of gravity (weightlessness) for a long time negatively affects his health. Coordination is broken. movements, changes in the metabolic system occur, muscles lose strength and decrease in size. Due to reduced load and lack of compression, the astronaut's spine begins to grow.

Due to the fact that on the details of the suit, reinforcing strips of elastic material are placed, made with the possibility of adjusting the tension and fixing, as well as due to the operation of the automatic system of intake and exhaust valves in a pulsating mode, in zero gravity conditions it is possible to create a load simulating muscle contraction . Under the influence of pulsating air, nerve fibers transmit excitement, the walls of blood vessels react, and reserve capillaries open. Such a massage “attack” allows you to work out and further maintain in tone even very weak muscles. In addition, not only muscles, but also the skin are maintained in tone, and blood microcirculation improves. This allows you to improve lymphatic drainage, thereby reducing the likelihood of swelling. The proposed design of the suit allows you to use absolutely all excitable structures, thereby providing sufficient load for a long stay of a person in zero gravity

The drawing shows a General view of the gravitational suit for work on a spaceship and an orbital station,

The suit is made of a polyurethane elastic fabric and consists of a jacket 1 with gloves 2, pants 3 and a hood 4, on which reinforcing strips of elastic material, a belt 5, made with the possibility of tight connection of the jacket 1 and pants 3 in tension mode are placed. Jacket 1 is equipped with an automatic valve system, configured to operate in a pulsating mode and consisting of inlet 6 and outlet 7 valves located on both sides of the jacket 1 at chest level, and reinforcing bands 8 of elastic material located on the jacket 1 and pants 3, made with the possibility of adjusting their length and fixing with tension at the level of the tight-fitting belt 5, and on both sides of the hood 4 symmetrically located reinforcing bands 9 fixed in its upper part are also made e with the ability to adjust the tension and fixation, the lower end of which is fixed to the reinforcing strip 10 located on the jacket along the shoulder girdle.

The gravitational suit for work on a spaceship and an orbital station is used as follows.

The costume is worn on the human body to ensure its life in outer space.

Through the inlet valve 6, air is supplied to the jacket 1 of the suit in a pulsating mode, which fills it and compresses the musculoskeletal system from all sides. Due to the fact that jacket 1 meets the tightness requirement, which is ensured by the presence of a tight belt located between the pants and the jacket, and a reinforcing strip 10 located on the jacket along the shoulder girdle, the air entering jacket 1 does not enter either the hood 4 or pants 3.

The reinforcing bands 8 located on the jacket 1 and tightly connected to it by a belt 4 pants 2, are stretched, exerting constant pressure on the muscles of the musculoskeletal system of a person in vertical and horizontal directions, compressing the spine, simulating the action of gravitational forces on the Earth.

Reinforcing strips 9 located on the hood 3 and connected to the jacket 1 of the suit along the shoulder girdle, allow you to adjust the compression of the cervical spine. Resisting this pressure, the muscles are under constant load. Reinforcing strips 8, 9 and 10, which are placed on the details of the suit, when tensioned, simulate Earth's gravity and avoid liming of the joints, cervical, thoracic and lumbar spine, while providing the necessary load. The pulsating air supply mode provides vibration and massage to the chest and arms.

The regulation of the air supply process is carried out using the exhaust valve 7, which operates in a pulsating mode.
