Description

Technical field

The technical solution relates to an assembly of an active respiratory protective device essentially as an overpressure air scrubber applied directly to the protected person. The technical solution belongs to the area of personal protective and hygienic needs of a person.

Prior art

At present, various methods are known for protecting humans, in particular against infection by pathogenic viruses. The lowest degree of protection is the application of hygienic drapes. But no hygienic drapes or respirators will guarantee their wearer 100% protection against infection. Conventional sanitary napkins are intended to protect the patient from microorganisms exhaled by healthcare professionals. They are therefore insufficient in the case of protection against coronavirus. This is partly due to the fact that they do not fit enough to the wearer's face. However, they can be used for the infected person to at least partially eliminate the spread of the disease to the environment.

Respirators are a higher degree of protection. Some types of respirators provide a higher level of protection, even under certain conditions. For the highest possible efficiency, it is necessary to take certain measures: choose a suitable respirator in terms of type and shape, put it on correctly and wear it correctly. It is a matter of course to observe other preventive measures, especially hand hygiene, etc. In the world, the N95 respirator is most often preferred for protection against Chinese coronavirus. Such a respirator protects its wearer from 95% airborne particles with a diameter of 0.3 μm or more. The equivalent of American N95 in our conditions could be respirators marked FFP2. However, FFP3 respirators provide the highest level of protection. These filter up to 99% of particles up to 0.6 μm in size. Respirators are manufactured with or without an exhalation valve. The exhalation valve ensures greater wearing comfort, as it reduces exhalation effort, but also, for example, the risk of fogging the glasses. However, if the respirator wearer is already infected - the respirator with the valve should be avoided so that the respirator wearer does not infect its surroundings. One of the possibilities is to use a respirator with built-in glasses, which can increase protection against viruses or bacteria, as the infection can spread through the eyes.

A higher level of protection not only against viruses can be achieved by using a protective half mask or mask in combination with a suitably selected filter. Half masks are also among the protective work aids and their task is not only to protect the respiratory tract, but also to guarantee comfort even when worn for a long time. Half masks are suitable for those who wear glasses and are maintenance-free - no record keeping is required. Protective work half masks always have two replaceable filters with a long service life and an exhalation valve to reduce heat accumulation.

Protective masks are multifunctional protective work aids and are used as respiratory protection. Full-face protective masks e.g. The 3M and Spirotck brands guarantee high wearing comfort and protection against a wide range of risk factors. Protective masks come in several sizes and each one can also be individually adapted to the shape of the head. Lightweight and ergonomically shaped protective mask is designed for use in various industries.

In the state of the art, there are analogous solutions of diving suits with an "oxygen bottle" for firefighters or welders in a dangerous environment with closed air circulation, but these are not usable in normal social contact.

The disadvantages of the described protective devices are that the protective drapes, respirators and shields do not provide a sufficient supply of fresh air, which causes difficult breathing. In the case of drapes, in addition, the exhaled air, including pollutants, is largely inhaled.

The not yet fully explored issue of methods of protecting humans, especially from infection by pathogenic viruses, has now evoked the Covid 19 coronavirus pandemic to propose a method of protecting the individual that would allow natural breathing, effective exchange of inhaled / exhaled air, and its easy application. The result of this effort is the active respiratory protective device assembly described in this technical solution.

The essence of the technical solution

Deficiencies in the state of the art in the field of personal protective and hygienic needs of humans, especially against viruses, are solved by the proposed set of active respiratory protective devices according to the technical solution. For the purposes of this technical solution, it is necessary to understand that the term "active" expresses the fact that the respiratory protective device, e.g. the drape is blown outside filtered air and the air of persons is just exhaled through the drape. It is a simple version of the solution, which ensures only the basic functionality, namely the supply of filtered air with the existing fixed protection of the veil, shield or respirator type, etc. The essence of the solution spo

S K 63-2020 U1 is that the active respiratory protective device assembly consists of an air handling unit which is connected by a hose to the respiratory protective device. The air handling unit consists of an air filter, an air compressor and a power bank, while the hose is connected to the air compressor. The air compressor connected to the powerbank by vacuum sucks in air through a HEPA filter (ideally a SuperHEPA filter, which also captures a coronavirus of size 0.125 pm) and pushes the filtered air through an infusion tube inserted under the drape. The assembly is variable in that the respiratory protective device is a drape or shield or a respirator or respiratory half mask or respiratory full face mask. The use of an air filter is also variable. The air filter is a HEPA filter or preferably a SuperHEPA filter, while other suitable types of filters may be used.

The advantages of the active respiratory protective device assembly according to the technical solution are obvious from its effects, which are manifested externally. The effects and originality lie in its unique composition. It is basically an overpressure air washer applied directly to the protected person. Special filters (HEPAfilter, SuperHEPA or other suitable type of filter) clean the air from microparticles, including coronavirus up to 0.125 pm. Pressurized drape, even if made of another fabric, prevents the penetration of possible infected ambient air with lower atmospheric pressure

The benefits of the solution according to the technical solution are: supply of healthy and fresh air at the time of social separation, elimination of inhaled exhaled air, the possibility of normal social life, including work and sports.
