Description
Patentsøknad: Beskyttelsesmaske med UV-C desinfisering Patent application: Protective mask with UV-C disinfection
Oppfinnelsens område Field of the invention
Oppfinnelsen er maske for å beskytte seg mot patogene og smittsomme stoffer som virus og bakterier. Masken dekker mund, nese og øyne og har minst en kanal eller åpning for pusteluft. Maskens funksjon er å beskytte bæreren mot å innånde sykdomsfremkallende og helsefarlige aerosoler. The invention is a mask to protect oneself against pathogenic and infectious substances such as viruses and bacteria. The mask covers the mouth, nose and eyes and has at least one channel or opening for breathing air. The function of the mask is to protect the wearer from inhaling disease-causing and health-threatening aerosols.
Oppfinnelsen omfatter en maske bygget opp av følgende elementer: Et beskyttende lag i helt eller delvis gjennomsiktlig materiale som dekker bærerens mund, nese og øyne, minst en åpning for pusteluft, dertil koblet vifte som skaper et overtrykk på innsiden av masken, et dertil koblet filter og et dertil koblet luftbehandlingskammer som er utstyrt med en eller flere UV-C lyskilder. The invention includes a mask made up of the following elements: A protective layer in fully or partially transparent material that covers the wearer's mouth, nose and eyes, at least one opening for breathing air, connected to it a fan that creates an overpressure on the inside of the mask, a connected filter and an air treatment chamber connected thereto which is equipped with one or more UV-C light sources.
Luftbehandlingskammeret har innsider som helt eller delvis er lysreflekterende. Luften på utsiden av masken passerer først gjennom viften, deretter gjennom et filter av et porøs filtermateriale, og deretter gjennom et eget behandlingskammer som er adskilt fra inn- og utsiden av masken og har valgfri utforming, og som utsetter pusteluften for en pulserende eller konstant UV-C stråling, før luften ledes videre mot brukerens mund og nese. The air treatment chamber has insides that are fully or partially light-reflective. The air on the outside of the mask passes first through the fan, then through a filter of a porous filter material, and then through a separate treatment chamber that is separate from the inside and outside of the mask and has an optional design, and which exposes the breathing air to a pulsating or constant UV -C radiation, before the air is directed towards the user's mouth and nose.
Oppfinnelsen omfatter således et beskyttelses-skjold, en elektrisk styrt vifte, en filter-enhet og et UV-C kammer med elektrisk lyskilde. I tillegg inneholder oppfinnelsen en styringsenhet med sensorer for lyskilden og viften, og en strømkilde, eksempelvis et batteri. Sistnevnte deler kan være integrert som del av masken, eller bæres som en separat beholder på kroppen, eksempelvis i snor rundt halsen, eller med spenne i beltet. The invention thus comprises a protective shield, an electrically controlled fan, a filter unit and a UV-C chamber with an electric light source. In addition, the invention contains a control unit with sensors for the light source and the fan, and a power source, for example a battery. The latter parts can be integrated as part of the mask, or worn as a separate container on the body, for example in a string around the neck, or with a buckle in the belt.
UV-C stråling i området 260 -280 nm har vist seg effektiv i kampen mot virus, og brukes idag i blant annet drikkevannsbehandling og ventilasjonsanlegg til bygg. UV-C radiation in the 260-280 nm range has proven effective in the fight against viruses, and is used today in, among other things, drinking water treatment and ventilation systems for buildings.
Kjent teknikk Known technique
Oppfinnelsen bygger på kjent teknikk for en maske utstyrt med filter og understøttet av en vifte som skaper overtrykk. Slike masker har vært kjent lenge og tilbys både som beskyttelses- utstyr for sandblåsere, malere og andre håndverkere. Som eksempel på patenter kan nevnes US5655527A. The invention is based on known technology for a mask equipped with a filter and supported by a fan that creates excess pressure. Such masks have been known for a long time and are offered both as protective equipment for sandblasters, painters and other craftsmen. Examples of patents include US5655527A.
Respirasjonsmasker brukes i medisin, der pasienten får tilført oksygen gjennom en port i en tett-sittende maske. Respiratory masks are used in medicine, where the patient is supplied with oxygen through a port in a tight-fitting mask.
Medisinsk personell bruker ofte en fiber-basert maske kombinert med en brille eller et enkelt ansikts-skjold i form av en tynn, bøyd og gjennomsiktig plastskjerm. Medical personnel often use a fiber-based mask combined with glasses or a simple face shield in the form of a thin, bent and transparent plastic screen.
Ulemper med kjent teknikk Disadvantages of prior art
Med dagens kjente løsninger har man valget mellom en tettsittende maske med porter for inn- og utånding, som legger et ubehagelig trykk på partier av ansiktshuden, og som mange bærere oppfatter som meget ubehagelig, og en løs-sittende maske eller skjerm som ikke gir tilstrekkelig beskyttelse på grunn av lekkasje inn mot nese og mund. Dagens masker er egnet å filtrere ut visse typer og størrelser aerosoler, men er lite egnet til å takle virus og andre mindre aerosoler. Virus smitter gjennom dråpesmitte og som enkelt-aerosoler som kan finne veien inn gjennom slimhinner i nese, øye og mund. With today's known solutions, one has the choice between a tight-fitting mask with ports for inhalation and exhalation, which puts an uncomfortable pressure on parts of the facial skin, and which many wearers perceive as very uncomfortable, and a loose-fitting mask or screen that does not provide sufficient protection due to leakage into the nose and mouth. Today's masks are suitable for filtering out certain types and sizes of aerosols, but are not suitable for dealing with viruses and other smaller aerosols. Viruses are transmitted through droplet transmission and as single aerosols that can find their way into the mucous membranes of the nose, eyes and mouth.
Formål med oppfinnelsen Purpose of the invention
Formålet med oppfinnelsen er å skaffe til veie en maske som gir effektiv beskyttelse mot virus og andre små aerosoler og som er behaglig å bære over lengre tid. The purpose of the invention is to provide a mask which provides effective protection against viruses and other small aerosols and which is comfortable to wear for a long time.
Hvordan formålene oppnås How the objectives are achieved
Formålene oppnås ved trekk angitt i etterfølgende krav. The objectives are achieved by features specified in subsequent requirements.
Fordeler av oppfinnelsen går også fram av beskrivelsen og de etterfølgende krav. Advantages of the invention are also apparent from the description and the following claims.
Det nye med oppfinnelsen er at man har en innebygget UV-C strålingskilde som behandler pusteluften før den innåndes. Lyskilden kan eksempelvis kobles til styringsenhet og sensorer slik at strålingen slås på ved innånding og av ved utånding, eller at den pulserer. UV-C strålingen inaktiverer virus og bakterier. What is new about the invention is that it has a built-in UV-C radiation source that treats the breathing air before it is inhaled. The light source can, for example, be connected to a control unit and sensors so that the radiation is switched on when you inhale and off when you exhale, or that it pulses. The UV-C radiation inactivates viruses and bacteria.
En videre fordel med den nye oppfinnelsen er at masken er behaglig å bære samtidig med at den er trygg og effektivt. Dette oppnås ved at masken ikke ligger tett mot ansiktshuden, men med en meget liten avstand slik at overtrykk vifteluft og utåndet luft kan unnvike gjennom denne smale åpningen. A further advantage of the new invention is that the mask is comfortable to wear while being safe and effective. This is achieved by the mask not being close to the skin of the face, but with a very small distance so that overpressured fan air and exhaled air can escape through this narrow opening.
Beskrivelse av avbildninger: Description of images:
Teknisk sett er det to mulige prinsipper for å feste masken til hodet: enten ved bruk av stropper eller strikk, eller ved hjelp av en bøyle over ørene. Technically, there are two possible principles for attaching the mask to the head: either using straps or elastics, or using a hoop over the ears.
I vedlagt skjematisk avbildning A er det vist et eksempel for en praktisk utførelse ifølge oppfinnelsen, en maske vist fra siden, bestående av gjennomsiktig hoveddel (1) med port for friskluft(2) i front, og bøyle over ørene(3). Avbildning B viser samme eksempel for en praktisk utførelse ifølge oppfinnelsen, maskens hoveddel frontal (1), med luftinntak og vifte (2) i senter, og friskluftåpninger på innsiden av masken (6). In the attached schematic illustration A, an example of a practical embodiment according to the invention is shown, a mask seen from the side, consisting of a transparent main part (1) with a port for fresh air (2) in the front, and a hoop over the ears (3).
