Definitions

• the subject-matter of the invention is an autonomous mask protecting against particulate matter, in particular as an urban mask, a dust mask or an antidust and anti-microbial mask, an anti-smog mask and an inhalation device.
• Known solutions of this type usually consist of a piece of cloth or plastic formed in such a way as to cover mouth and nose, and a single- or multi-stage filtration system.
• Patent No. US4141703A applies to a polymer dust mask equipped with a multi-stage filter.
• KR20110022975A relates to a mask with a medicinal plant grounded to powder and wrapped inside the cloth of the mask.
• US20130007945A1 relates to a mask adhering to the entire surface of the face and tied at the back of the head which warms the skin of the face.
• Patent No. GB976614A relates to a respiratory head mask with a heating element put between the layers of the masks forming its walls.
• Patent No. CA2337434 relates to a mask with an exhalation valve to facilitate expiration.
• a known and beneficial solution in mask production including masks that perform additional functions, is to include a valve that facilitates exhalation and limits evaporation onto the mask.
• This solution is to enable inhalation or nebulization using a mask that could function independently and not as part of a larger system, and to combine flow, heating and/or ultrasonic techniques that allow the inhaled substance to evaporate in such a way as to allow to create a user-friendly device with limited energy consumption.
• the mask according to the invention is a dust-resistant mask equipped with a container for a liquid for inhalation, whose outlet is the inner side in relation to one or more filters.
• the mask is equipped with a flow channel with a narrowing inside, preferably in the form of a venture tube, at the height of the outlet of the liquid container.
• it has an element for absorbing water through capillary action, preferably a cotton wool or permeable surface, preferably gauze; with a layer in contact with the air in the vent, preferably at the height of the end of the narrowing of the vent.
• a positive effect occurs when an element or a permeable surface made of a substance or material that absorbs liquids through capillary action is adjacent to the heating system.
• the mask housing is equipped with a heating system, adjacent to the liquid container, in its position mounted inside the mask.
• the mask housing is equipped with an ultrasonic system, preferably comprising a probe immersed inside the liquid container in its mounted position inside the mask, equipped with a battery and preferably a motherboard. Additional benefits are achieved when the mask housing is equipped with at least one one-way valve blocking the inflow and allowing for the outflow of air from the inside of the mask.
• the heating system is equipped with a battery and preferably a motherboard.
• the mask housing is equipped with a membrane/mesh system, comprising a porous membrane inside the liquid container in its mounted position inside the mask, equipped with a battery and preferably a motherboard.
• the device according to the invention is in the form of a device for inhalation or nebulization using a liquid substance placed in a liquid containe, characterized in that it takes the form of a dust mask, preferably a mask with a HEPA filter, and has a housing of a mask. It is also beneficial if the device is equipped with a flow channel, inside which there is a narrowing, preferably in the form of a venturi, at the height of the outlet of the liquid container. In preferred embodiments, it has an element for absorbing water through capillary action, preferably a cotton wool or permeable surface, preferably gauze; with a layer in contact with the air in the vent, preferably at the height of the end of the narrowing of the vent.
• a positive effect occurs when an element or a permeable surface made of a substance or material that absorbs liquids through capillary action is adjacent to the heating system. Additional benefits are achieved when the mask housing is equipped with a heating system, adjacent to the liquid container, in its position mounted inside the mask.
• the mask housing is equipped with an ultrasonic system, preferably comprising a probe immersed inside the liquid container in its mounted position inside the mask, equipped with a battery and preferably a motherboard. Additional benefits are achieved when the mask housing is equipped with at least one one-way valve blocking the inflow and allowing for the outflow of air from the inside of the mask.
• the heating system is equipped with a battery and preferably a motherboard.
• the mask housing is equipped with a membrane-mesh system, comprising a porous membrane inside the liquid container in its mounted position inside the mask, equipped with a battery and preferably a motherboard.
• Fig. 1 shows a mask equipped with a liquid container, the outlet of which is at the end of the flow channel in a front view
• Fig. 2 is a cross-section of the device from Fig. 1 in side view
• Fig. 3 is the cross-section of the device from Fig. 1 in isometric view.
• the device in the embodiment has a flow channel 1 with a narrowing 2 along its length from outside to the inside of the mask in the form of a straight venturi, the end of which is at the outlet of the liquid container 3. It has four elements 4, partly located inside the flow channel and partly inside the liquid container 3 in its mounted position.
• the mask in its exemplary embodiment is equipped with a heating system 6, adjacent to the liquid container 3, in its position mounted inside the mask.
• the mask housing 7 is equipped with a onesided valve 9 blocking inflow and allowing for air outflow from the inside of the mask.
• the heating system is connected to the motherboard 10 and the battery 11.
• the mask is equipped with a set of filters 12, located inside the flow channel 1, on the outer side in relation to the liquid container 3 and the narrowing of the flow channel 2 along the length from the outside to the inside of the mask.
• the subject matter according to the invention allows for easy inhalation or nebulization using a substance placed in a removable container.
• Both the heating system that increases the temperature of the inhaled or nebulized substance and the narrowing of the flow, allow achieving critical pressure at a given temperature and evaporation of the substance to be nebulized.
• These actions can be performed interchangeably or supplement each other in order to obtain the desired process efficiency at the expense of low energy consumption and increased resistance in the vent Evaporation can also be achieved through the ultrasonic module; however, this results in high frequency noise.
• the evaporating effect can also be achieved through the membrane/mesh system.
• the methods can be combined to optimize efficiency and energy consumption.
• the narrowing of the vent may take the form of an orifice or half orifice to limit the length of the flow channel; however, due to the desired minimization of resistance within the vent, the use of a venturi is beneficial for the flow.
• the use of the subject-matter according to the invention allows, in addition to limiting external harmful factors, to treat, among others, sinuses, throat, larynx, trachea, bronchi and lungs and to facilitate steroid therapy. It allows for proper hydration of the respiratory tract and elimination of fungal, bacterial and viral infections.
• the additional one-sided valve allowing the outflow of air, facilitates breathing and limits evaporation inside the mask.
