Description
Područje tehnike na koje se izum odnosi Technical field to which the invention relates
Izum spada u područje tehnike zaštitnih osobnih sredstava zaštitnih maski za lice koje služe za zaštitu zdravlja organa za disanje koje su prema međunarodnoj klasifikaciji proizvoda klasificirane kao A41D13/11. The invention belongs to the technical field of personal protective equipment, protective face masks that serve to protect the health of the respiratory organs, which according to the international classification of products are classified as A41D13/11.
Tehnički problem za čije se rješenje traži zaštita Technical problem for the solution of which protection is requested
Tehnički problemi za čije se rješenje traži zaštita jesu: The technical problems for which protection is requested are:
- nepoželjno udisanje dijela zaostalog izdisaja ispod maske koje se pojavljuje kod upotrebe postojećih jednokratnih i višekratnih zaštitnih maski za lice sa naborima, - undesirable inhalation of part of the residual exhalation under the mask, which occurs when using existing disposable and reusable protective face masks with folds,
- otežano udisanje koje je posljedica ovlaživanja materijala maski vlažnim izdisajem koje se pojavljuje kod upotrebe postojećih jednokratnih i višekratnih zaštitnih maski za lice sa naborima. - difficulty inhaling, which is a consequence of wetting the material of the masks with moist exhalation, which occurs when using existing disposable and reusable protective face masks with pleats.
Stanje tehnike područja izuma State of the art in the field of invention
Sadašnje stanje tehnike postojećih jednokratnih i višekratnih zaštitnih maski za lice sa naborima je takvo da sve one formiraju samo jedan prostor ispod njih odnosno između lica i njih u kojemu se odvijaju i udisaj i izdisaj zbog čega prilikom udisaja neminovno dolazi do udisanja dijela izdisaja koji se je zadržao ispod maske. Kao što je poznato, izdisaj je vlažniji i topliji od svježeg okolnog zraka te sadrži ugljični dioksid (CO2) što je nepoželjno za udisaj odnosno za zdravlje. Takav vlažniji izdisaj ovlažuje materijal maske čime se smanjuje mogućnost protoka kroz nju što otežava udisanje. Zaostali izdisaj ispod maske smanjuje količinu udisaja svježeg zraka. Sve to zajedno dovodi do određene nelagode prilikom disanja kroz postojeće gore navedene maske. The current state of the art of the existing disposable and reusable protective face masks with folds is such that they all form only one space below them, that is, between the face and them, in which both inhalation and exhalation take place, which is why, during inhalation, the inhalation of a part of the exhalation that is kept under the mask. As is known, exhalation is more humid and warmer than the fresh surrounding air and contains carbon dioxide (CO2), which is undesirable for inhalation and for health. Such wetter exhalation moistens the material of the mask, which reduces the possibility of flow through it, which makes inhalation difficult. Retarded exhalation under the mask reduces the amount of fresh air inhalation. All this together leads to a certain discomfort when breathing through the existing masks mentioned above.
Bit izuma The essence of invention
Primami cilj izuma je eliminacija nepoželjnog udisanja dijela zaostalog izdisaja odnosno CO2 ispod maske koje se pojavljuje prilikom nošenja postojećih jednokratnih i višekratnih zaštitnih maski za lice sa naborima. The primary goal of the invention is the elimination of unwanted inhalation of part of the residual exhalation, i.e. CO2 under the mask, which appears when wearing existing disposable and reusable protective face masks with pleats.
Sekundarni cilj je eliminacija otežanog udisaja koji je posljedica ovlaživanja izdisajem materijala maski koje se pojavljuje prilikom nošenja postojećih jednokratnih i višekratnih zaštitnih maski za lice sa naborima. The secondary goal is the elimination of difficult inhalation, which is a consequence of the wetting of the mask material by exhalation, which occurs when wearing the existing disposable and reusable protective face masks with pleats.
Bit izuma je u podjeli unutarnjeg stražnjeg dijela maske na dva odvojena dijela: jedan dio za udisaj a drugi dio za izdisaj. Tako, gornji dio sa stražnje strane maske koji pokriva nos služi za udisaj, a donji dio sa stražnje strane maske koji pokriva usta služi za izdisaj. Inače, sama prethodno navedena podjela stražnjeg dijela maske na dva odvojena dijela ostvaruje se ugradnjom pregrade od zrakonepropusne brtve između njih na srednjem naboru što je dano u detaljnom opisu izvođenja izuma u daljnjem tekstu. The essence of the invention is the division of the inner back part of the mask into two separate parts: one part for inhalation and the other part for exhalation. Thus, the upper part on the back of the mask that covers the nose is used for inhalation, and the lower part on the back of the mask that covers the mouth is used for exhalation. By the way, the previously mentioned division of the rear part of the mask into two separate parts is achieved by installing a partition made of an airtight seal between them on the middle fold, which is given in the detailed description of the implementation of the invention below.
Ovaj izum u odnosu na postojeće jednokratne i višekratne zaštitne maske za lice sa naborima omogućava uvijek normalni nesmanjeni udisaj svježeg okolnog zraka kroz nos te normalni izdisaj kroz usta. Inače, i sa samog zdravstvenog stanovišta je ispravno udisanje kroz nos jer se tako: filtrira, ovlažuje i zagrijava okolni zrak čime se smanjuje mogućnost infekcija. Nadalje, sa zdravstvenog stanovišta je poželjnije izdisati kroz usta jer se tako izdiše više CO2 nego kroz nos. Pored prethodno navedenog, prilikom nošenja maske s predmetnim izumom ne dolazi do zamagljivanja naočala kod osoba koje ih nose pošto se izdisaj vrši kroz usta kroz donji dio maske koji ne dopire do naočala. Compared to existing disposable and reusable protective face masks with pleats, this invention always enables normal, unreduced inhalation of fresh ambient air through the nose and normal exhalation through the mouth. By the way, breathing through the nose is also correct from a health point of view, because it: filters, humidifies and warms the surrounding air, which reduces the possibility of infections. Furthermore, from a health point of view, it is preferable to exhale through the mouth, because this way more CO2 is exhaled than through the nose. In addition to the above, when wearing a mask with the invention in question, there is no fogging of the glasses of the person who wears them, since exhalation is done through the mouth through the lower part of the mask that does not reach the glasses.

Detaljan opis izvođenja izuma Detailed description of the implementation of the invention
Osnova maske s navedenim izumom u potpunosti je identična današnjim na tržištu prisutnim zaštitnim respiracijskim jednokratnim i višekratnim maskama za lice s naborima: pamučnim, višeslojnim nemedicinskim i višeslojnim kirurškim. Te maske se sastoje od tijela maske (1) uobičajene širine 17,5 cm te uobičajene visine 9,5 cm. The basis of the mask with the mentioned invention is completely identical to the protective respiratory disposable and reusable pleated face masks on the market today: cotton, multi-layer non-medical and multi-layer surgical. These masks consist of a mask body (1) with a normal width of 17.5 cm and a normal height of 9.5 cm.
Tako je osnova maske tijelo sa tri nabora sa prednje strane (5), (6), (7) te tri nabora sa stražnje strane (9), (10) i (11). Nabori su kod pamučnih maski učvršćeni na lijevom i desnom kraju šivanjem. Nabori su kod višeslojnih nemedicinskih i višeslojnih kirurških maski učvršćeni na lijevom i desnom kraju lijepljenjem. Maske imaju elastične vezice za uši (2) učvršćene na uglovima tijela maske. Vezice za uši su kod pamučnih maski učvršćene šivanjem, a kod višeslojnih nemedicinskih i višeslojnih kirurških maski lijepljenjem. Te maske imaju i traku za nos (4) izrađenu od plastificirane žice koja je kod pamučnih maski opšivena u njih, a kod višeslojnih nemedicinskih i višeslojnih kirurških je oblijepljena u njih. Thus, the basis of the mask is the body with three folds on the front (5), (6), (7) and three folds on the back (9), (10) and (11). In the case of cotton masks, the pleats are fixed at the left and right ends by sewing. In multi-layer non-medical and multi-layer surgical masks, the pleats are fixed at the left and right ends by gluing. The masks have elastic ear ties (2) fixed at the corners of the mask body. For cotton masks, the ear ties are fixed by sewing, and for multi-layer non-medical and multi-layer surgical masks, they are fixed by gluing. These masks also have a noseband (4) made of plasticized wire, which is hemmed into them in the case of cotton masks, and in the case of multi-layer non-medical and multi-layer surgical masks, it is glued into them.
Maska s opisanim izumom, pored prethodno navedenih dijelova, ima: The mask with the described invention, in addition to the previously mentioned parts, has:
- zrakonepropusnu pregradu (8) sa unutarnje strane maske na srednjem naboru (10) na cijeloj njegovoj duljini izuzev obruba, - the air-tight partition (8) on the inside of the mask on the middle fold (10) along its entire length except for the border,
- dodatne elastične vezice za uši (3) učvršćene s prednje strane maske na liniji pregrade odnosno srednjeg nabora. - additional elastic ear ties (3) fixed on the front side of the mask on the line of the partition or middle fold.
Pregrada je kvadratnog presjeka dimenzija 8x8 mm izrađena od sintetičke gume elastomera EPDM tvrdoće približno 50 ShA koji je zrakonepropustan, ima visoku otpornost na: starenje, prema utjecaju atmosfere te visokim i niskim temperaturama koji je kao takav pogodan za predmetnu pregradu. The partition has a square cross-section, dimensions 8x8 mm, made of synthetic elastomer EPDM rubber with a hardness of approximately 50 ShA, which is air-tight, has a high resistance to: aging, the influence of the atmosphere and high and low temperatures, which is suitable for the partition in question.
Pregrada se na pamučne, višeslojne nemedicinske i višeslojne kirurške maske s naborima pričvršćuje lijepljenjem ljepilom za tekstil i gumu. The partition is attached to cotton, multi-layer non-medical and multi-layer surgical masks with pleats by gluing with textile and rubber glue.
Pregrada maske s opisanim izumom dijeli unutarnji stražnji dio maske na dva odvojena dijela, jedan gornji stražnji dio maske koji služi za udisaj kroz nos te drugi donji stražnji dio maske koji služi za izdisaj kroz usta čime se omogućava uvijek normalni nesmanjeni udisaj svježeg okolnog zraka kroz nos te normalni izdisaj kroz usta. The partition of the mask with the described invention divides the inner back part of the mask into two separate parts, one upper back part of the mask that is used for inhalation through the nose and the other lower back part of the mask that is used for exhalation through the mouth, which enables always normal, unreduced inhalation of fresh ambient air through the nose and normal exhalation through the mouth.
Gore navedeni materijal od kojega je izrađena pregrada se nalazi na tržištu kao višenamjenska elastična EPDM brtva raznih oblika i dimenzija. The above-mentioned material from which the partition is made is available on the market as a multi-purpose elastic EPDM seal of various shapes and dimensions.
Dodatne elastične vezice za uši služe za ostvarivanje prianjanja pregrade za lice odnosno brtvljenja između pregrade i lica radi odvajanja gornjeg stražnjeg dijela maske za udisaj od donjeg stražnjeg dijela za izdisaj. Dodatne elastične vezice za uši mogu biti opremljene sa na tržištu dostupnim standardnim stoperima za podešavanje zategnutosti vezica radi boljeg ostvarivanja prianjanja pregrade na lice obzirom na različite veličine glave. Additional elastic ear ties are used to achieve adhesion of the partition to the face, i.e. sealing between the partition and the face in order to separate the upper back part of the mask for inhalation from the lower back part for exhalation. Additional elastic ear ties can be equipped with standard stoppers available on the market to adjust the tension of the ties in order to achieve a better adherence of the partition to the face considering different head sizes.
Način primjene izuma Method of application of the invention
Ovaj izum je primjenjiv kao zaštitno osobno sredstvo koje služi za zaštitu zdravlja organa za disanje. This invention is applicable as a personal protective device that serves to protect the health of the respiratory organs.
Ovaj izum podjele stražnjeg dijela maske na dva odvojena dijela primjenjiv je na sve sadašnje na tržištu jednokratne i višekratne zaštitne maske za lice sa naborima koje formiraju samo jedan prostor ispod njih: pamučne, višeslojne nemedicinske i višeslojne kirurške. This invention of dividing the back of the mask into two separate parts is applicable to all disposable and reusable protective face masks currently on the market with pleats that form only one space underneath: cotton, multi-layer non-medical and multi-layer surgical.
Ovaj izum naročito je primjenjiv za osobe koje tijekom obavljanja posla neprekidno više sati nose masku kao što je medicinsko osoblje jer kod ovog izuma se udisanjem kroz nos uvijek udiše svjež okolni zrak i ne dolazi do otežanog udisaja zbog ovlaživanja materijala maske izdisajem. This invention is especially applicable for people who continuously wear a mask for several hours while performing their work, such as medical personnel, because with this invention, by inhaling through the nose, fresh surrounding air is always inhaled and there is no difficulty in breathing due to the moistening of the mask material with exhalation.
Ovaj izum nije primjenjiv kod osoba sa brkovima i bradom pošto se kod njih ne ostvaruje dobro brtvljenje zbog propuštanja između pregrade i brkova i brade na kojem se položaju sama pregrada nalazi. This invention is not applicable to people with mustaches and beards, since they do not have a good seal due to leakage between the partition and the mustache and beard, in which position the partition itself is located.
