Description

Technical field

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

Prior art

Today, the world is still plagued by the COVID 19 pandemic. Large cities are infested with smog. Asthmatics and allergy sufferers suffer from airborne allergens. In enclosed spaces, infections spread among people. Workers from multiple cliffs must work in a dusty environment.

Various methods are currently known for protecting humans, in particular against infection by pathogenic viruses, in general by microorganisms. The lowest degree of protection is the application of hygienic drapes. However, no hygienic drapes or respirators will guarantee their wearer 100% protection against infection. This is partly due to the fact that they do not fit enough to the wearer's face.

Respirators are another level of protection. Some types of respirators provide a higher level of protection, even under certain conditions. For maximum 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. In the world of sav, the N95 respirator is most frequently examined in connection with 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. FFP3 respirators provide the highest level of protection. These filter up to 99% of particles up to 0.6 μm in size. However, protective drapes, shields and respirators do not provide a light and safe supply of fresh air, which makes breathing difficult. In addition, in the case of drapes, a large part of the already exhaled air, including pollutants, is inhaled. Solid protective devices also do not allow for good and intelligible narration.

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, which belong to the protective work aids.

Full-face protective masks e.g. 3M, CleanSpace and Spirotck brands provide protection against a wide range of risk factors. The ergonomically shaped protective mask is intended for use in various industries but is not suitable for normal social contact.

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 also not usable in normal social contact.

The not yet fully explored problem of methods of protecting humans, especially against infection by pathogenic viruses and microorganisms, has evoked the current colonies of the coronavirus Covid 19 to propose a method of protecting the individual that would allow natural breathing, effective exchange of inhaled / exhaled air and its simple application. The aim is to provide a solution for anyone who wants to protect themselves from air pollutants (viruses, bacteria, smog, dust, pollen, etc.) and provide them with a supply of healthy and clean air anywhere and in any activity within the framework of normal social contact (work, sports, shopping in a store, traveling by bus or plane, waiting room at the doctor, etc.). The result of this effort is the active respiratory protective device 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 and pathogenic microorganisms, are solved by the proposed active respiratory protective device 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. external filtered air is blown into the drape, which is in close contact with the person's face, for inhalation under pressure, and the air is exhaled through the drape or through leaks between the drape and the face. Or, in the case of a shield used which is advanced in front of the face, external filtered air is blown under pressure into the central open space between the shield and the face for inhalation and the air is exhaled through the peripheral space between the shield and the face. Or in the case of a used respirator that is in close contact with a person's face, external filtered air is blown into the respirator-enclosed space for inhalation under pressure and the air is exhaled by an exhalation valve. It is a simple version of the solution that provides basic functionality with the supply of filtered air with existing fixed protection. type drape, shield or respirator. The essence of the solution lies in the fact that the active respiratory protective device consists of at least one air-conditioning unit formed by at least one air filter, power bank resp. a source of electrical energy such as a battery or accumulator, etc., controls2

With K130-2020 U1 cou electronics and at least one air pressure / flow device having a pneumatic connection directly to the respiratory protective device or at least to the space of the respiratory protective device. Of course, the air pressure / flow device also has a pneumatic connection to the air filter. For the purposes of this technical solution, a drape or a transparent elastic or rigid shield or a shield from an air curtain or a respirator can be used as a respiratory protective device. It is also possible to use an air filter from the HEPA or SuperHEPA or ULPA type series or another suitable type of filter or combination of filters. For the purposes of this technical solution, a compressor or a fan or a blower can be used as the air pressure / transport device. The device for pressurization / air flow is connected to the powerbank and sucks air through the air filter, which also captures the coronavirus of the size of about 0.125 pm The filtered air is pressed under pressure by a pneumatic connection to the respiratory protective device. For the purposes of this technical solution, a breathing hose, flex tube, pipe or duct in some part of the device can be considered as a pneumatic connection. Then there are several options for bringing clean filtered air to a person's face. If a drape or respirator is used, the filtered air can be brought to the face by sliding the outlet of the tubing or flex tube under the drape or respirator, thereby creating an air overpressure under the drape or respirator. If a respiratory protective device is used e.g. a transparent plastic shield in front of the person's face covering at least the nose and mouth area, if any, then the outlet of the pneumatic connection in the area of the respiratory protective device is terminated by several nozzles, the direction of which can create a stable slightly pressurized area with clean filtered air for inhalation, wherein the pneumatic connection could again be realized by hoses or flexural tubes and the like. An alternative to a transparent plastic shield mounted in front of a person covering at least the nose and mouth or face area is an air curtain shield realized by a pneumatic connection in the area of a respiratory protective device terminated by at least two directed nozzles to form a shield from the air curtain.

From a design point of view, the solution provides many possibilities of how and where to place, mount the air handling unit as a compact unit or its individual components, which do not have to be grouped into one compact unit, but can be separately distributed in a structurally active respiratory protective device while maintaining their interconnections and functional connection.

In one implementation, the air handling unit forms one compact unit with the included air filter, power bank and air pressure / flow device. In this case, the skeleton of the air handling unit has fastening body elements, which can be e.g. Velcro tapes or rubber zippers with which the skeleton of the air handling unit is attached, e.g. on a person's shoulder or belt. The fastening body elements can also be straps which are fastened to the air handling unit and the strap is carried vertically or obliquely over the person's shoulder. The fastening body elements can be e.g. leather or plastic eyes by which the air handling unit is put on the belt. In the simplest case, the air handling unit can only be inserted into a bag, handbag, pocket of clothes, etc.

In the second embodiment, the air handling unit again forms one compact unit with the contained air filter, power bank and air pressure / flow device, this air handling unit being implemented in a clamping head skeleton with at least one control element. In this case the clamping head skeleton is formed by a flexible half-bulb extending through the top of the head from the left ear to the right ear. The left and right air handling units are located in the area of the ears in the end parts of the flexible half-block. In an analogous solution, only one air handling unit can be inserted into the flexible half-bulb thus formed, extending through the top of the head from the left ear to the right ear. The second part of the flexible half-block would remain free, or some other supporting elements of the active respiratory protective device would be placed. In an analogous solution, the air handling unit can have its structural elements distributed throughout the construction of the clamping head skeleton, where e.g. in the area of the left ear, only the pressure / air flow device would be located in the clamping head skeleton, in the area of the right ear, only the air filter would be located in the clamping head skeleton, and in the central top region of the flexible half-block of the clamping head skeleton. power bank as a source of electricity.

The active respiratory protective device can also be solved in such a way that at least one of the elements such as: loudspeakers, microphone, camera, augmented reality projector is implemented in the clamping head skeleton. LED lighting, photovoltaic cells, breath analyzer, humidifier, shield holder. E.g. the loudspeaker, breath analyzer and shield holder can be placed in the second free part of the flexible half-block of the clamping head skeleton, as described above. Alternatively, the camera, augmented reality projector, LED lighting and photovoltaic cells may be located in the upper parietal portion of the flexible half-block of the clamping head skeleton.

In a third embodiment, the air handling unit again forms one compact unit with an air filter, a power bank and an air pressure / flow device, this air handling unit being implemented in a clamping head skeleton with at least one control element. In this case, the clamping head skeleton is formed by a headband. The left is symmetrically placed in the area of the skeleton's ears

S K130-2020 U1 and right air handling unit. It is also possible to insert only one air handling unit in the area of one ear of the flexible headband. The second part of the headband would remain loose, or some other supporting elements of the active respiratory protective device would be placed there. The clamping head skeleton formed by the headband can be supplemented by one or two face holders in which the channels of the pneumatic connection of the air pressure / flow device with the respiratory protective device can be guided.

In another embodiment, the air handling unit again forms one compact unit with the included air filter, power bank and air pressure / flow device, this air handling unit being implemented in a clamping neck skeleton. In this case, the clamping neck skeleton is formed by a half-block from the back of the person's body encircling the person's neck. The clamping neck skeleton can be supplemented by one or two face holders in which the channels of the pneumatic connection of the air pressure / flow device with the respiratory protective device can be guided.

Because the space under the veil, t. j. the space between the face and the veil has an overpressure of clean filtered air, greater than the ambient atmospheric pressure, so contaminated air e.g. pathogenic microorganisms since the drape is on the outside at atmospheric pressure does not have the possibility to penetrate through the drape into the airways of a person. As a result, the drape does not have to be made of a breathable material, but can be made of transparent plastic. The person's exhaled air would leave the space under the veil through leaks between the adjacent drape and the face. Respectively, it would be possible to provide systems of openings through which the continuously filtered clean filtered air supplied by the air pressure / flow device would be discharged and at the same time the air exhaled by a person would be forced through the same openings. This philosophy could also be applied to a respirator, which would also be made of transparent plastic. However, the expiration of the exhaled air would be through the exhaust valve of the respirator, which would be embedded in a clear plastic. Such solutions are not self-serving but fulfill the function of immediate natural contact between communicating persons, because communicating persons perceive the whole person's face even with their mouths and moving lips during communication.

It is also possible for a sophisticated solution, where the clamping head / neck skeleton with face holders are implemented in the helmet. Then at least one of the elements such as: speakers, microphone, front camera, augmented reality projector, LED lighting, photovoltaic cells, breath analyzer, air humidifier, shield holder, essential oil reservoir can be placed in the clamping head / cramped skeleton.

The advantages of an active respiratory protective device according to the technical solution are obvious from its effects, which are manifested externally. The effects and originality lie in its unique set, which is basically an overpressure air washer applied directly to the protected person. Special filters (HEPA, SuperHEPA, ULPA or other suitable type of electrostatic, isocatalytic and UV filter) purify air from microparticles including coronavirus up to 0.125 μm in several steps. The system e.g. the microturbines of the compressor, blower or fan in turn ensure the supply of such filtered air directly in front of the nose and mouth in a volume of 3 to 8 Emin. The vital capacity of the lungs, ie the amount of air that is exchanged at maximum exhalation after maximum exhalation, is about 3.5 l in women and 5 Emin on average in men. In addition, a separate air distribution with a higher pressure and a volume of more than 16 Emin, creates a cloud-shaped air shield in front of the face using a system of directional microdozzles. This ensures that the filtered air does not disperse into the outside environment and, on the expensive side, protects the person from inhaling the outside unfiltered air. Pressurized drape resp. the respirator, even if only made of plain fabric, prevents the penetration of possible infected ambient air with a lower atmospheric pressure.

Beneficial solutions according to the technical solution are: supply of healthy filtered and fresh air at the time of social separation, elimination of inhaled exhaled air, the possibility of normal social life, including work and sports. In addition, the built-in exhaled air analyzer can detect thousands of gaseous compounds in the breath and isolate those associated with viruses and other pathogens in the air, allowing quick and timely diagnosis and for yourself and your surroundings to allow the individual and society to function over time. social distance. The highest version for demanding conditions includes electronic equipment, which includes a microphone, speaker, front image and infrared camera, headup projector of augmented reality and bluetoth interface for connection to a smartphone, photovoltaic cells for charging, outdoor LED lighting. The solution is modular, the basic elements are e.g. flow generator - blower, compressor or other device for pressurization / air flow, system of replaceable filters, energy sources of various capacities and several possible ways of supporting components. The basic elements can be extended with additional protection modules and smart functions. The solution is scalable, providing several levels of protection from the affordable basic version, through the extended to the highest to the toughest conditions.
