Invenția se refera la o masca semideschisa, transparenta sau mata, reutilizabila, care protejează împotriva diseminării germenilor, si in special a virusurilor, care se pot transmite prin picaturile de saliva si secretii nazale, respectiv prin picaturile Fltigge.The invention relates to a semi-open, transparent or matte, reusable mask, which protects against the spread of germs, and especially of viruses, which can be transmitted through saliva drops and nasal secretions, respectively through Fltigge drops.

Odata cu izbucnirea virusului SARS-CoV-2, raspandirea agentilor patogeni aeropurtati a devenit o mare preocupare din cauza impactului sau potențial.With the outbreak of the SARS-CoV-2 virus, the spread of airborne pathogens has become a major concern due to its potential impact.

Măștile chirurgicale, cunoscute si sub numele de masti de fata, sunt destinate purtării de către profesioniștii din domeniul sanatatii in timpul procedurilor de asistenta medicala. Acestea sunt concepute pentru a preveni infecțiile pacientilor si pentru tratarea personalului prin captarea bacteriilor conținute in picaturi de lichid si aerosoli din gura si nasul purtătorului. Nu sunt concepute pentru a proteja purtătorul de inspirația bacteriilor sau a virusurilor aerieni ale căror particule sunt mai mici. In ceea ce privește unele infectii, cum ar fi gripa, acestea apar la fel de eficiente ca aparatele respiratorii, cum ar fi măștile N95 sau FFP; deși acestea din urma oferă o protecție mai buna in experimentele de laborator datorită materialului, formei si etansarii complete.Surgical masks, also known as face masks, are intended to be worn by healthcare professionals during healthcare procedures. They are designed to prevent patient infection and to treat staff by capturing bacteria contained in drops of liquid and aerosols from the wearer's mouth and nose. They are not designed to protect the carrier from the inspiration of bacteria or airborne viruses whose particles are smaller. As for some infections, such as the flu, they are just as effective as respirators, such as N95 or FFP masks; although the latter provide better protection in laboratory experiments due to the material, shape and complete sealing.

Pe perioada pandemiei, oamenii trebuie sa poarte masti. Din pacate, foarte putini le poarta corect, acuzand greutatea in respirație, faptul ca li se aburesc ochelarii, faptul ca nu li se vede fata, etc., de cele mai multe ori lasand nasul in afara. Purtarea incorecta a măștii echivalează cu nepurtarea ei. Mai mult, deși măștile chirurgicale sunt destinate doar unei singure utilizări, majoritatea folosesc o masca mai multe zile, mărind probabilitatea transmiterii virale.During the pandemic, people have to wear masks. Unfortunately, very few wear them correctly, blaming the weight on their breath, the fact that their glasses are steaming, the fact that their face is not visible, etc., most of the time leaving their nose out. Improper wearing of the mask is equivalent to not wearing it. Moreover, although surgical masks are for single use only, most use a mask for several days, increasing the likelihood of viral transmission.

Sunt cunoscute mai multe soluții tehnice referitoare la masti transparente si/sau semideschise, toate urmărind teoretic protecția împotriva diseminării germenilor.Several technical solutions are known for transparent and / or semi-open masks, all theoretically aimed at protecting against the spread of germs.

Este cunoscut brevetul US2008092909A1 care se refera la o masca de fata universala, transparenta, care cuprinde o porțiune centrala transparenta, o porțiune exterioara care o înconjoară si este fixata de porțiunea centrala transparenta, si unul sau mai multi agenti antimicrobieni. Aceasta soluție tehnica propune o masca greu de utilizat si scumpa de produs.U.S. Patent No. 2,092,909A1 is disclosed, which relates to a universal, transparent face mask comprising a transparent central portion, an outer portion surrounding it and fixed to the transparent central portion, and one or more antimicrobial agents. This technical solution proposes a mask that is difficult to use and expensive to produce.

Mai sunt cunoscute brevetele WO2009104442A1, JP2009011475A si JP2013046647A care se refera la o masca transparenta al cărei corp este compus dintr-o porțiune superioara transparenta realizata dintr-un material transparent si o porțiune inferioara de filtrare a ventilației realizata dintr-un material respirabil, cum ar fi o tesatura. Aceste soluții tehnice propun masti dificil de utilizat, scumpe de produs si care trebuie schimbate periodic.WO2009104442A1, JP2009011475A and JP2013046647A are also known, which refer to a transparent mask whose body is composed of a transparent upper portion made of a transparent material and a lower ventilation filtering portion made of a breathable material, such as be a fabric. These technical solutions offer masks that are difficult to use, expensive to produce and must be changed periodically.

Mai sunt cunoscute brevetele CN209359732U, CN204697940U, CN104886823A si CN204697941U, care se refera la masti transparente formate dintr-o diafragma transparenta si un suport pentru bărbie, asa fel incat, ramane un spațiu de respirație inAlso known are CN209359732U, CN204697940U, CN104886823A and CN204697941U, which refer to transparent masks consisting of a transparent diaphragm and a chin rest, so that it remains a breathing space in

-1 RO 135561 Α2 partea superioara a măștii. Aceste soluții tehnice nu protejează împotriva diseminării germenilor, diseminarea fiind chiar amplificata de expirația prin partea superioara a măștii.-1 EN 135561 Α2 the upper part of the mask. These technical solutions do not protect against the spread of germs, the spread being even amplified by the expiration through the upper part of the mask.

Dezavantajele soluțiilor tehnice cunoscute constau in aceea ca măștile sunt dificil de purtat pe perioade extinse, in special de persoanele care poarta ochelari, nu pot filtra in totalitate particulele de dimensiuni mici, cum ar fi virusurile, si ascund total sau parțial figura purtătorului, cu efecte sociale in special asupra copiilor si tinerilor.The disadvantages of the known technical solutions are that the masks are difficult to wear for extended periods, especially by people who wear glasses, can not completely filter small particles such as viruses, and completely or partially hide the figure of the wearer, with effects especially on children and young people.

Masca semideschisa, conform invenției, elimina dezavantajele soluțiilor cunoscute, prin aceea ca, se compune dintr-o parte naso-piramidala superioara care imbraca piramida nazala si nasul, si corpul principal, care are porțiunile laterale in contact cu obrajii, si partea inferioara libera, semideschisa, permițând trecerea aerului respirat. Fata anterioara a corpului măștii are suprafața convexa către interior, asa fel incat, aerul expirat sa se deplaseze exclusiv in jos datorita efectului Coanda.The semi-open mask, according to the invention, eliminates the disadvantages of the known solutions, in that it consists of an upper naso-pyramidal part covering the nasal pyramid and the nose, and the main body, which has the lateral portions in contact with the cheeks, and the free lower part, semi-open, allowing air to pass through. The front face of the body of the mask has a convex surface inwards, so that the exhaled air moves exclusively downwards due to the Coanda effect.

Problema pe care o rezolva invenția consta in realizarea unei masti semideschise, transparente, reutilizabile care poate fi purtata atat cu prindere clasica, după urechi, cat si atașata ochelarilor sau unei rame special concepute, fara a ascunde fata purtătorului. Mai mult decât atat, masca semideschisa poate fi utilizata suficient de comod in cafenele, restaurante, si chiar la înot. Masca asigura o protecție completa împotriva diseminării germenilor prin proiecția in jos a aerului expirat, către sol.The problem solved by the invention is to make a semi-open, transparent, reusable mask that can be worn both with a classic grip, behind the ears, and attached to glasses or a specially designed frame, without hiding the wearer's face. Moreover, the semi-open mask can be used comfortably enough in cafes, restaurants, and even for swimming. The mask provides complete protection against the spread of germs by projecting the exhaled air down to the ground.

Invenția prezintă următoarele avantaje:The invention has the following advantages:

- Datorita pârtii inferioare libere, semideschise, masca asigura respirația cu ușurința, fara a crea disconfort respirator;- Due to the free, semi-open lower part, the mask ensures easy breathing, without creating respiratory discomfort;

Datorita efectului Coanda produs de forma convexa la interior a fetei anterioare, masca împiedica transmiterea la distanta a picaturilor de saliva si secrețiilor nazale ale purtătorului (picaturile Flugge), directionandu-le in jos;Due to the Coanda effect produced by the convex shape on the inside of the anterior face, the mask prevents the long-distance transmission of saliva drops and nasal secretions from the wearer (Flugge drops), directing them downwards;

Toate versiunile măștii sunt special create pentru a nu produce aburirea ochelarilor;All versions of the mask are specially designed to prevent misting of the glasses;

Masca este ușoara si comod de purtat;The mask is light and comfortable to wear;

Poate fi data ușor jos, împreuna cu ochelarii sau rama de susținere;It can be easily lowered, together with the glasses or the support frame;
