Abstract

FIELD: equipment for protection respiratory organs against harmful effects, particularly for individual protection in crowds.

SUBSTANCE: method for protection of respiratory organs against air-borne infections, for instance causing respiratory diseases, involves directing sterile respiratory gas flow tangentially to imaginary surface defined by nose tip, chin and jaws in area of respiratory organs. Transversal dimension of flow section is not less than above area dimension so that ambient air is prevented from entrance into the flow and ambient air is substituted with the gas flow directly in respiratory organs area in amount necessary to sustain breathing. To carry out above method compressed sterile breathing air source, gas flow control valve and means for gas delivery to respiratory organs, distribution and discharge thereof are used.

EFFECT: increased reliability of breathing apparatuses protection along with elimination of visible protective means on central user's face part.

Description

The invention relates to the field of protection of the respiratory organs from harmful effects on health and can be used as individual protection in crowded places, for example, public transport, in the seasons of mass diseases and epidemics of diseases transmitted by air, as well as in other adverse circumstances for the body , for example in places of severe gas contamination.

Known methods of protection against diseases transmitted by air. These include individual masks covering the area of the respiratory organs, the working fluid of which is a mechanical filter, for example, an ordinary two-, three-layer gauze or bandage, as the easiest and most affordable way, easy and most convenient. An example is the “Respirator” A.S. No. 1824200 (A 62 B 18/00), which is proposed for convenience to manufacture with a rigid, lightweight frame, by impregnating the filter with a styrene copolymer. Other respirators, such as the “Respirator” RU 2026094 (A 62 B 7/10, 18/00), also have certain technical advantages and a certain comfort, but are already more voluminous and heavy.

All respirators cover a significant part of the face, making it not very attractive. Gas masks with all their technical advantages in this series are the most unpretentious. All these products are quite suitable, practical and harmonious for those conditions for which they were created as professional accessories - medicine, dusting plants, smoky and chemical plants. However, in other conditions, not production, where in the minds of people not expediency prevails, but the dictates of public opinion with attributes such as aesthetics, ethics, etc. and the desire for self-identification, where the enemy is pathogenic microorganisms, is not obvious, people (overwhelming majority) cannot force themselves to put on some kind of device protecting their respiratory organs, since the face area with the most characteristic features is not only closed, but also takes on a common belief ridiculous appearance. Estimated moral costs are more convincing than the real risk of a two-week physical malaise. It is obvious that today the level of technology that performs the function of protecting the respiratory organs from the penetration of microorganisms does not meet the needs of time and people.

At the same time, it cannot be said that people are indifferent to their health, they are looking for other ways to prevent the disease, for example, by saturating the air with air ions in residential and office premises, using medications with preventive purposes or for the first symptoms of the disease - all the less willingly.

So, for example, methods and devices are known for influencing the respiratory organs and pathways by the method of therapeutic inhalation, for example, a.s. USSR No. 1554915 (A 61 M 15/02). The impact is provided for powerful, but, alas, already for the diseased organism, i.e. to combat the effect of insecurity of the body affected by the disease. More effective - to preempt the disease, including fight the cause.

Thus, for example, every flu epidemic from a pseudo-ethical problem develops into an economic one in the number of lost work days and into a problem of a general weakening of the nation’s health.

The purpose of the invention is a method that provides portable and effective means of protecting the human respiratory system from carriers of airborne infections, eliminating the presence of visible, material protection of them on the central part of the face.

The technical result is achieved in that the protection is carried out using a stream of sterile respiratory gas, the axis of which coincides with the direction of the tangent to the imaginary surface formed by the tip of the nose, chin and jaws, in the respiratory region, and the transverse, tangential size of the flow section is not inferior to the corresponding size the specified area, protecting it with its ablation from the penetration of external air into it, which it replaces directly in the area of the respiratory system, provides It is the needs of the body’s breathing, for which they use a source of compressed sterile respiratory gas, which regulates the gas flow valve and means of gas delivery to the respiratory organs, its distribution and release.

As a source of compressed sterile respiratory gas, a gas spray can be used with a 1-hour supply of gas in which the gas is under pressure, or a portable individual respiratory gas sterilizer consisting of the following elements: mechanical gas cleaning, pressure-exhaust device, disinfectant generator, chamber gas sterilization, gas neutralizer.

Protection can be carried out using either one or several flows of sterile respiratory gas directed to the respiratory region from different sides.

Respiratory gas, depending on the circumstances and the additional purpose of use, is used with a different percentage of oxygen and other gases, including negative air ions, as well as medical, perfume and other components.

The source of compressed sterile respiratory gas may be, for example, in a clothing pocket or autonomously, for example, on a belt. The purpose of the means of distribution and release of gas in the formation of a stream (or flows) of a certain cross-section, emanating from a certain place, with an appropriate option for attaching, for example, to clothing, headgear, body, for example to the head. They must have sufficient degrees of freedom to provide a simple adjustment of the flow direction. Between the gas source and the gas distribution and discharge means, a gas delivery means and a gas flow control valve are arranged. All the elements necessary for the implementation of the method can be combined in one compact device that easily fits in the palm of your hand. The individual determines the need to turn on the protective device, assessing the risk of each individual situation, for example, public transport at rush hour.

The proposed method is carried out after the protective device is turned on, when the flow of sterile respiratory gas, passing along a tangent to an imaginary surface in the area of the respiratory organs, externally blows off (carries away) the surrounding air adjacent to them from the respiratory organs with possible carriers of infection, while simultaneously respiratory nutrition with sterile respiratory gas, i.e. by myself. The effectiveness of the application of the method depends on the individual's assessment of the situation and the beginning of its application, on the geometric characteristics of the flow and its trajectory with respect to the region of the respiratory system, on the intensity of the gas flow regulated by the corresponding valve.
