RU163525U1 - SOFT HELMET, FOR PROTECTION OF RESPIRATORY BODIES - Google Patents

Abstract

1. A soft helmet that serves to protect the user's respiratory organs, using a ventilation system open to the air outlet, comprising a protective cap made of soft, gas-tight, heat-resistant material with a viewing window, air inlet and outlet nodes, with neck sealing, characterized in that that a power frame is placed inside the protective cap, to which an inspection window, air inlet and outlet nodes are attached outside the protective cap, and which protects the user's head from external impacts and fixing soft helmet on the user's head by means of cervical belt quick-lock, which allows the user to work in a polluted atmosphere and effectively bezopasno.2. A soft helmet according to claim 1, characterized in that on the front side of the soft helmet is attached a pad for protection from external influences. 3. A soft helmet according to claim 1, characterized in that a cape of soft elastic material is fixed to the protective cap of the soft helmet to protect it from pollution.

Description

This device relates to the field of human life support and serves for individual protection of the respiratory system of the user from the penetration of contaminated air, gases, smoke from the environment.

In the constructions under consideration, ventilation systems of breathing devices open to the air outlet are used.

From the current level of technology, a known analogue of a soft helmet is a "rescue breathing device .."., Patent RU 2124375, publ. 01/10/1999

Structurally, this is a protective mask made of soft material with a plastic viewing window, with neck sealing and the device "for feeding under the mask of the respiratory mixture."

The disadvantage of this technical solution is the insecurity of the user's head in a soft mask from external influences.

The closest analogue is the "Protective mask" containing "a hemispherical screen, patent RU 2243795, publ. 10.01.2005,

The disadvantages of the device include:

the complexity of manufacturing a "hemispherical mask with optical transparency"; the location of the "exhaust nozzle" with a safety valve in the face of the user.

The task to which the claimed technical solution is directed is to expand the arsenal of technical means in this area.

The technical device proposed for consideration, comprising a protective cap 2, (Fig. 1), made of soft, gas-tight, heat-resistant material, with a viewing window, air inlet and outlet nodes, with neck sealing, placed on the protective cap, is realized by placing inside the protective cap soft helmet of the power cage 1, (Fig. 1), to which the inspection window, air inlet and outlet nodes are attached to the outside of the protective cap, thereby protecting the user's head from external influences.

The essence of the device is illustrated by drawings, which depict:

In fig. 1 and fig. 2 shows a soft helmet when viewed from the side and front;

In fig. 3 shows a power cage.

The device of a soft helmet and work in it.

Air enters the soft helmet for breathing through the travel sleeve from an external source, and the exhaled air and fresh air mixed with it exits from the back of the soft helmet through air outlet 4 (Fig. 1.).

In a soft helmet ventilation is used with an open air outlet through an opening that performs the function of a throttle.

The diameter of the outlet depends on the magnitude of the applied pressure and is set by adjusting so that there is always high pressure in the soft helmet. The pressure in the soft helmet must be such that the user does not feel any physiological effect from the pressure.

In a soft helmet, the user breathes as usual, without the use of facial obturators or mouthpieces. The fixation of the soft helmet on the user's head is ensured by fastening the protective cap of the soft helmet on the user's neck with the help of a quick-release tape lock 5, (Fig. 1).

This lock also serves to seal the protective cap of the soft helmet on the user's neck.

Pressure fluctuations in a soft helmet, from the user's breath, does not affect the position of the viewing window.

In fig. 3 shows the power frame, consisting of an oval headband 1, with platforms fixed thereon: under the viewing window 2; nodes of the air inlet 3 and air outlet 4. The novelty of the device also includes the use of Pads 7, (Fig. 4) on the front of the soft helmet, to protect the viewing window from external influences, and the use of Pads 8, (Fig. 4) from the soft, elastic material on a protective cap, for protection against pollution.

Examples of using a soft helmet:

1. When painting;

2. When working with fiberglass;

3. At enterprises with harmful production conditions.

The advantages of a soft helmet include the possibility of replacing, if necessary, a protective cover due to damage, pollution or for hygienic reasons.

The task to which the claimed technical solution is directed is to expand the possibilities of using a soft helmet in those areas of human activity where respiratory protection is relevant.

Claims (3)

1. A soft helmet that serves to protect the user's respiratory organs, using a ventilation system open to the air outlet, comprising a protective cap made of soft, gas-tight, heat-resistant material with a viewing window, air inlet and outlet nodes, with neck sealing, characterized in that that a power frame is placed inside the protective cap, to which an inspection window, air inlet and outlet nodes are attached outside the protective cap, and which protects the user's head from external impacts and fixing soft helmet on the user's head by means of cervical belt quick-lock, which allows the user to work in a polluted atmosphere, efficiently and safely. 2. A soft helmet according to claim 1, characterized in that on the front part of the soft helmet is attached a pad for protection from external influences. 3. A soft helmet according to claim 1, characterized in that a cape of soft elastic material is fixed to the protective cap of the soft helmet to protect it from pollution.
