[0001] The utility model relates to the technical field of respiratory filtration, in particular to a sticky nose mask. Background Art

[0002] In an environment with air pollution, in order to prevent harmful substances from entering the respiratory system, a filter device that can filter the air inhaled through the nose is needed in life or work, so as to prevent the occurrence of diseases and reduce the harm caused by external air pollution to the human body.

[0003] Currently, common respiratory filtration devices include masks or nasal masks, but in actual use, the applicant has found that although the current masks and nasal masks can play an air filtration role to a certain extent, they still have some shortcomings.

[0004] Currently, most masks and nasal masks are of two types: ear-hanging type and head-hanging type. During use, masks and nasal masks with ear-hanging structure will cause marks or redness and swelling on the ears, while masks or nasal masks with head-hanging structure will cause messy hairstyle and tight head, which greatly reduces the wearing comfort. The seal is formed by squeezing the edge of the product and the face, and the sealing effect is poor. Utility Model Content

[0005] In view of this, the utility model proposes an adhesive nasal mask to solve the problems of low wearing comfort and sealing performance of existing ear-hanging and head-hanging nasal masks.

[0031] The following will be combined with the implementation of the utility model to clearly and completely describe the technical solutions in the implementation of the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] like Figure 1 As shown, combined Figure 2-5 The utility model discloses an adhesive nasal mask, comprising a nasal mask body 1, wherein the nasal mask body 1 has a cavity 10 adapted to the human nose, thereby the nasal mask body 1 can be worn on the face and cover the human nose. In order to ensure that the nasal mask body 1 can be stably worn on the face and form a sealed fit with the nose, the nasal mask body 1 is set to be made of medical silicone material in this embodiment, and the inner surface of the cavity 10 of the nasal mask body 1 can be adhered to the surface of the nose except the nostrils. Specifically, the nasal mask body 1 is made of medical silicone, which is usually harmless when in contact with the skin, does not cause allergic reactions, and does not cause skin irritation. Therefore, it is suitable for applications in which the skin is closely attached for a long time. This material can softly adhere to the entire nose skin except the nostril area, thereby providing a stable and comfortable wearing experience.

[0033] In addition, the nose mask body 1 disclosed in this embodiment is formed into the shape of a nose using a medical silicone sheet. Since the medical silicone sheet is self-adhesive, it can be perfectly adhered to the surface of the nose to achieve a fit, thereby improving the sealing between the nose mask and the nose surface. The nose mask disclosed in this embodiment uses a medical silicone sheet. Due to the softness and self-adhesiveness of the medical silicone sheet itself, it can be repeatedly pasted and taken and used at any time without the need for an additional lanyard, which enhances the wearing comfort of the nose mask and has a high degree of sealing effect.

[0034] In order to filter the inhaled air, the present embodiment further provides a through hole 11 corresponding to the nostril on the nasal mask body 1, and the inner surface of the cavity 10 of the nasal mask body 1 is provided with a filter layer 2 for covering the through hole 11. With the above-mentioned structural arrangement, since the inner surface of the cavity 10 of the nasal mask body 1 can be adhered to the surface of the nose except the nostrils, the nasal surface above the nostrils can be completely fitted with the inner surface of the cavity 10 of the nasal mask body 1, so that a closed chamber is formed between the bottom of the nostril and the filter layer 2. By providing the filter layer 2 at the through hole 11, the breathed air can be filtered, and the filter layer 2 can effectively intercept harmful substances, while cooperating with the through hole 11 to maintain air circulation.

[0035] Although the nasal mask body 1 disclosed in the present embodiment is formed into the shape of a human nose using a medical silicone sheet, under normal circumstances, the inner contour of the cavity 10 should be slightly larger than the outer contour of the human nose. Since the nose of each person is of different sizes, after the nasal mask body 1 covers the human nose, there is a gap between the nasal mask body 1 and the surface of the nose. Although the nasal mask body 1 is self-adhesive, due to the elasticity of the nasal mask body 1 itself, during long-term wearing, the nasal mask body 1 may be detached from the surface of the nose, which will reduce the sealing performance on the one hand, and on the other hand, there is a risk of the entire nasal mask falling off.

[0036] To this end, in this embodiment, an adhesive is provided on the inner surface of the cavity 10 of the nasal mask body 1, which is used to detachably mount the nasal mask body 1 on the face. The surface of the inner cavity 10 of the nasal mask body is provided with an adhesive, which is specially designed to be reversible, so that the nasal mask can be easily attached to the user's face and can be easily removed when needed. The characteristics of this adhesive allow the nasal mask body to fit the nose skin while maintaining its reusability.

[0037] The key to selecting an adhesive is its friendliness to the skin, proper adhesion, and easy cleaning. This design ensures that the nasal mask remains in place to provide effective filtration, while also allowing the user to remove the nasal mask without any obstacles when it is not needed, so as to facilitate breathing and rest of the facial skin. The adhesive of this embodiment can also be made of sub-sensitive adhesive, acrylic adhesive, hydroxy acrylic adhesive, silane cross-linked adhesive, etc. The preferred adhesive of this embodiment is a medical adhesive. Medical-grade adhesives can protect the skin from damage and reduce irritation to sensitive skin, and can be removed without leaving residue.

[0038] In this embodiment, the design of the nasal mask further takes into account the need for a close fit with the human face. A structure called a side wing 12 is formed at the extended portion of the outer edge of the cavity 10 of the nasal mask body 1. These side wings 12 are used in the nasal mask design to enhance the overall adhesion effect and improve the wearing comfort. In addition, through the provision of the side wings 12, it can fit completely with the face, further improving the sealing effect.

[0039] In order to achieve a close fit between the side wing 12 and the face, the inner surface of the side wing 12 is provided with a first adhesive 121. This adhesive can be a self-adhesive adhesive or a pressure-sensitive adhesive. The self-adhesive adhesive has a certain viscosity, and can maintain a good pasting effect after repeated pasting, and it is not easy to leave residual adhesive. The pressure-sensitive adhesive has the characteristic of increasing viscosity as the pressure increases. The user can adjust the pasting strength according to their own needs to obtain the best comfort and sealing.

[0040] In order to filter the air for breathing, this embodiment shows a preferred structural mode of the filter layer 2. Figure 6 As shown, the filter layer 2 includes a hydrophobic membrane 21 , a filter membrane 22 and a hydrophilic membrane 23 which are stacked in sequence, and the hydrophobic membrane 21 is in contact with the inner surface of the cavity 10 .

[0041] By adopting the above technical solution, the hydrophobic membrane 21 is tightly attached to the inner surface of the cavity 10 of the nasal mask body. The function of the hydrophobic membrane 21 is to block moisture and other liquid pollutants while allowing gas to pass through. The filter membrane 22, which can be made of activated carbon fiber or similar high-efficiency filter materials, is intended to capture particulate matter suspended in the air, chemical pollutants, and potential microbial pollutants, such as bacteria and viruses. Finally, close to the user's nasal cavity is a layer of hydrophilic microporous filter membrane 22. The microporous structure of this filter membrane 22 is designed to maintain good air circulation while intercepting tiny water molecules that may enter from the outside or harmful substances dissolved in water.

[0042] Through these three layers of specially designed filter materials, the nasal mask not only provides waterproof protection, but also can efficiently filter various potentially harmful substances, thereby providing users with fresh breathing air.

[0043] In some specific embodiments, the hydrophobic membrane 21 may be selected from, but not limited to, a polytetrafluoroethylene (PTFE) microporous membrane, a polypropylene (PP) microporous membrane, a polyethylene (PE) microporous membrane, etc.

[0044] Among them, polytetrafluoroethylene (PTFE) microporous membrane has high hydrophobicity and can effectively prevent the penetration of water and water-based liquids. Polypropylene (PP) microporous membrane has good air permeability and natural hydrophobic properties. Polyethylene (PE) microporous membrane is light, soft, and has excellent hydrophobic properties.

[0045] The filter membrane 22 may be activated carbon fiber or activated carbon nonwoven fabric. The activated carbon fiber has a fiber diameter of 5 to 20 μm and an average specific surface area of ​​1000 to 1500 m 2 / g, the average pore size is 1.0~4.0nm, and the micropores are evenly distributed on the fiber surface. Compared with activated carbon, the micropores of activated carbon fiber are small and uniform in size, simple in structure, fast in adsorption rate for adsorbing small molecules, high in adsorption speed, and easy to desorb. The contact area with the adsorbate is large, and it can be evenly contacted and adsorbed, so that the adsorption material can be fully utilized. It has high efficiency and has various fine surfaces such as fiber, felt, cloth and paper. The pores open directly on the fiber surface. The diffusion path of the adsorbate to reach the adsorption site is short, and the surface area itself is two orders of magnitude higher than the internal surface area. For some macromolecules or particulate substances, such as dioxins, dust, etc., the volume is close to or even larger than the volume of the micropores of activated carbon fiber, and it is difficult to be adsorbed, which is more advantageous than activated carbon.

[0046] The hydrophilic membrane 23 may be selected from, but not limited to, modified polytetrafluoroethylene (mPTFE) membrane, polysulfone (PSU) or polyethersulfone (PES) membrane or cellulose acetate membrane.

[0047] In order to facilitate repeated use of the nasal mask, the filter layer 2 is detachably arranged on the inner surface of the cavity 10 in this embodiment.

[0048] As an implementation method, refer to the attached Figure 1 and 3 As shown, the filter layer 2 is connected to the inner surface of the cavity 10 by bonding. Specifically, the outer surface of the hydrophobic membrane 21 of the filter layer 2 is provided with a second adhesive backing 20 for bonding to the inner surface of the cavity 10. When the filter layer 2 is replaced, the filter layer 2 can be adhered to the inner surface of the cavity 10 of the mask body 1 through the second adhesive backing 20. It is worth noting that before replacing the filter layer 2, the used filter layer 2 can be removed, and then the mask can be disinfected or cleaned, and then the new filter layer 2 can be adhered to the inner surface of the cavity 10, so as to facilitate the reuse of the mask of this embodiment.

[0049] As another embodiment, refer to the attached Figure 4 and 5As shown, the filter layer 2 is connected to the inner surface of the cavity 10 by a snap-fitting manner. Specifically, a snap-fitting slot 101 is provided on the inner surface of the cavity 10, and the filter layer 2 is snap-fitted into the snap-fitting slot 101. When replacing the filter layer 2, it is only necessary to remove the used filter layer 2 and then insert the new filter layer 2 into the snap-fitting slot 101 horizontally.

[0050] As some preferred embodiments, the nose mask body 1 is transparent or similar to the skin color. Thus, the whole nose mask is more beautiful and non-physical when worn on the nose.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
