Technical Field
The invention relates to the field of sanitary protection, in particular to a mask for protecting a respiratory system or a body surface.
Background
The mask is a sanitary article, generally refers to a device worn at the mouth and nose for filtering air entering the mouth and nose so as to prevent harmful gas, smell, spray, particles, viruses and the like from entering and exiting the mouth and nose of a wearer, and is generally made of gauze or non-woven fabrics and the like. The mask has different filtering standards in different application fields, has a certain filtering effect on air entering the lung, and has a very good effect when being worn in respiratory infectious diseases and working in environments polluted by dust and the like. The mask is also selected for the patients with respiratory diseases, pollen allergy and the need of protecting the facial skin.
Common mask types include medical surgical masks, disposable medical masks, filter-type particle-proof masks, self-priming filter-type dust masks, daily protective masks, knitted masks, and the like. The specific production and inspection standards can refer to YY0469-2011, YY/T0969-.
Taking a daily protective mask as an example, the protective effect of the mask can be divided into A, B, C, D four grades from high to low, the mask is respectively suitable for different air qualities from serious pollution to below moderate pollution, the basic requirements comprise that the mask can safely and firmly protect the mouth and the nose, the mask raw materials do not use regeneration materials, contain high-toxicity, carcinogenic or potential carcinogenic substances and known materials which can cause skin irritation or other adverse reactions, the residual quantity of other substances for limiting use can meet the related requirements, no peculiar smell is generated, the mask does not have sharp corners and sharp edges which can be contacted, no harm is caused to a wearer, the mask can be conveniently worn and removed, and the like. For medical surgical masks, medical protective masks and other types of masks, the corresponding technical requirements on filtering efficiency, materials, structures, quality and the like should be met.
Most of gauze masks at present, no matter medical gauze mask or daily type gauze mask, satisfying under the condition of certain protection standard, can't compromise the travelling comfort usually, the user need make the selection between safety and comfort, often its comfort level of gauze mask that the protection level is higher is also lower more moreover. In normal period, medical personnel are in high risk area, therefore higher to uncomfortable tolerance, and ordinary crowd is lower to the uncomfortable tolerance of gauze mask, but uses gauze mask mainly used for uses such as separation contaminated air and droplet, consequently generally need not wear for a long time, does not wear or select more comfortable but the gauze mask that protecting effect is poor according to the standard occasionally, can not produce serious influence.
However, during the world abuse of novel coronaviruses and under other conditions of outbreak of air-borne diseases, dense crowds, harsh environment and the like, the requirement on the tolerance of the mask wearing comfort is remarkably improved, even ordinary crowds can be in unknown high-risk areas at any time, in this case, serious consequences are likely to occur due to the fact that the mask cannot be worn according to standards due to the fact that the mask wearing discomfort is caused by mask protective articles, and the discomfort caused by the mask protective articles is mainly reflected in the moist and stuffy feeling of the mouth, nose and face.
Taking the new coronavirus epidemic situation period as an example, the temperature gradually rises along with the epidemic situation entering summer, and various masks with good barrier function can block the germs and simultaneously block the loss of facial moisture and heat. Taking a common medical disposable mask as an example, the face feels stuffy, moist and uncomfortable after being worn outdoors for 30 minutes, and the discomfort feeling is enhanced after being worn indoors for one hour. Although the metal wire nose clip is arranged on one side of the top of the mask and is attached to the nose bridge of a face through bending of the metal wire, sealing and filtering are kept, most of common users can loosen the nose clip due to sultriness, or the mask is frequently taken off for ventilation, so that bacteria, viruses and fine particles in the air can be inhaled under the condition of no filtering, and the risk is increased rapidly in places with dense stream of people such as markets, public transport means and the like. Even if medical personnel can insist on wearing the mask according to the standard, discomfort also exists, discomfort caused by the mask with high protection level is stronger, and the long-time wearing of the mask can result in dizziness, heatstroke and other consequences, thus affecting the health and the working efficiency.
Disclosure of Invention
In order to overcome the defects in the prior art, the invention provides a comfortable respirator, and aims to solve the problems that in the prior art, a user feels sultry, dizziness, dyspnea and the like due to wearing the respirator in a hot weather or closed or high-temperature environment, and the problems that the wearing of the respirator is not standard, the protection is not comprehensive, the working efficiency of the user is reduced and the like are caused. In order to achieve the purpose, the invention provides the following technical scheme:
The mask of
Scheme 7. the mask according to
The mask of
The mask according to
The mask according to any one of
Scheme 11. the mask according to
Scheme 12. a method for manufacturing a mask, characterized in that the multi-layer materials of the mask body described in the
Scheme 13. use of a mask, characterized in that the mask having the structure described in schemes 1-11 is used for protective or shielding purposes of a folding mask, a self-suction mask, a pet mask, a disposable mask, a reusable mask, a medical mask, a daily protective mask, a knitted mask, a sun-blocking mask or other types of masks.
The body feeling comfortable mask provided by the invention is suitable for any type of masks, and is mainly suitable for medical or civil masks with certain protection and shielding effects. The moisture absorption and ventilation material is used for the skin-friendly layer in contact with the skin, so that the accumulation of water vapor and heat between the mask and the face is reduced, comfortable and cool body feeling is provided for a user, however, in a common situation, due to the sealing and the blocking of the filter layer on the water vapor, the comfortable body feeling provided by the skin-friendly layer cannot be maintained for a long time, when the water vapor and the heat are accumulated more, reverse osmosis can occur, the inside of the skin-friendly layer is wet, and the reason that the skin-friendly material is only used for clothes or body surface sun-shading purposes is also provided.
When the moisture absorption layer is arranged between the skin-friendly layer and the filter layer, the moisture permeating through the skin-friendly layer can be absorbed and stored by the moisture absorption layer, so that a continuous osmotic pressure difference is provided, the face can be kept dry and cool for a long time, and the ventilation and cooling effects of the skin-friendly layer are fully exerted.
The skin-friendly layer fabric is preferably a material with high water vapor permeability and moisture content meeting the physiological requirements of human skin, for example, various types of common ice silk fabrics, bamboo charcoal fibers, or fabrics formed by twisting 70% of viscose filament yarns and 30% of nylon yarns in a cross way, common viscose fibers, high-tenacity fibers, viscose, acetate fibers, modal, modified cotton fibers and the like, and other chemical synthetic fibers such as common terylene, nylon, spandex and the like, or the types mentioned above, or blended fabrics of different fibers can be used. The skin-friendly layer fabric is made of materials which have good biological compatibility, no peculiar smell, no chlorine and various additives and have the content of residual chemical components reaching harmless standards. Various commodity brands and types with cool and breathable properties, such as Viscose fiber or Viscose labeled products, which are common in the market can be selected. For the skin-friendly fabric, certain hydrophilicity is preferred, and the skin-friendly fabric should show certain hygroscopicity, so that the moisture absorption is facilitated. However, it is advantageous for the water vapor that has passed through the fabric to reach the outer side of the skin-friendly layer not to be repeatedly sucked into the inner side, and therefore, the outer side of the skin-friendly layer can be made of hydrophobic fabric, which can be achieved by modifying the surface of the fabric during weaving or blending of the skin-friendly layer fabric, or by proportionally distributing materials on different sides during blending of different fabrics. Preferably, the fabric can be prepared by coating a hydrophobic coating on the outer side of the skin-friendly layer fabric, such as an organic silicon hydrophobic agent, and the like, wherein the coating is arranged so as not to influence the air permeability of the fabric. When the skin-friendly layer fabric has more than one layer or the weaving process allows different materials to be woven on the inner side and the outer side, the weaving can be realized according to the principle. The diameter of the fiber and the aperture and thickness of the fabric are suitable for comfortable and breathable feeling, and the thickness can be 0.1-2mm, preferably 0.2-1mm, and more preferably 0.3-0.6 mm.
The moisture-absorbing layer is preferably made of a material having a water-retaining function, such as those mentioned above, for example, absorbent paper, wood fiber, loose sponge, foam, nonwoven fabric, gauze, poly (meth) acrylate or a modified polymer thereof, polyvinyl alcohol or a modified polymer thereof, polyacrylamide or a modified polymer thereof, polyacrylonitrile or a modified polymer thereof, and the like, which can absorb and fix exhaled moisture, prevent the backflow of the moisture, and maintain the dryness of the skin-friendly layer. The material of the moisture absorption layer is preferably soft water absorption material, such as thin sponge or wood fiber, and the moisture absorption layer can be arranged in multiple layers or single layer, and can be designed to be in a removable and replaceable state according to the requirement of moisture absorption performance. Because the moisture-absorbing layer is adjacent to the skin-friendly layer, the material should also meet certain safety standards and have sufficiently low VOC and other harmful substances. For the disposable absorbent layer, absorbent modified materials such as acrylic or other absorbent resins can be used, which have the advantages of high moisture absorption rate and the disadvantages of denaturation that may cause pore blockage and air permeability reduction, and therefore, it is preferable to provide a support layer on which a water storage material is provided to maintain sufficient air permeability. Or the water storage material is set to be in a loose hole form, so that sufficient air circulation and shape stability can be still kept even after water absorption denaturation occurs. The thickness of the hygroscopic layer may be 0.1 to 2mm, preferably 0.5 to 1.5mm, and more preferably 0.8 to 1.2 mm. The moisture absorption layer is preferably provided in one layer, and may be provided in 2 or more layers. The moisture absorption layer can be can remove, for example can set up movable cover plate on gauze mask upper portion, and one end links to each other with the gauze mask body is innermost, and the other end covers in the superficial layer outside, and accessible nose presss from both sides during the use compresses tightly, can take out the water storage device as movable moisture absorption layer that the activity set up through the opening when opening, sunning or change.
For the case of reusing the mask, a non-denatured water storage material can be used on the moisture absorption layer, and only water vapor is absorbed, such as sponge, foam and the like. The mask is preferably made of a material which has high water absorbability and light weight, and the softness and comfort of wearing are not affected in the mask. Preferably loose porous material, with a certain support. It is also preferable to use a porous material together with other water-storing materials such as water-absorbing resin to constitute the main structure of the moisture-absorbing layer.
Under the special application condition, the moisture absorption layer needs to be used for a long time, so that the water storage performance of the moisture absorption layer has higher requirements, and at the moment, the moisture absorption layer is not enough to maintain the inner surface of the mask dry and comfortable by simply relying on the water storage layer, and a water vapor discharging device needs to be arranged on the moisture absorption layer. Preferably according to the gauze mask shape, set up the bar check valve along hygroscopic layer edge in the gauze mask bottom, can use rubber, elastomer or other materials as the valve plate, open along with the air current when exhaling, seal because of the negative pressure when breathing in to with unnecessary steam discharge, improve the dry and comfortable degree of close skin layer in the gauze mask.
The surface layer and the filtering layer can be made of corresponding conventional materials, such as those used by the existing mask, or can be selected according to specific application requirements, and the corresponding materials are selected according to the standards of protection and filtering. The surface layer is usually provided as one layer, but may be provided in other shapes or multiple layers according to aesthetic requirements. The filter layer may be those mentioned above, or may be a plurality of filter sheets used together. The filter layer is preferably one layer, and 2 or more layers may be provided. When a plurality of filter layers are provided, the moisture absorption layer may be alternately arranged with the filter layers or may be separately and collectively provided. For reusable masks, the filter is preferably removable and replaceable, for example, by providing a removable cover over the mask as described above, and replacing the filter. Sterilizing or oxidizing and adsorbing materials can be added to each layer of the mask, such as silver fibers, activated carbon and the like, and are co-spun with fabric fibers of each layer of the mask, and are melt-blown, or are coated on a moisture absorption layer, a skin-friendly layer, a filtering layer and a surface layer, so that the effects of inactivating bacteria and viruses, eliminating peculiar smell, removing harmful substances, and filtering, adsorbing and inactivating pollen can be achieved.
When the requirement on the protection effect is not high, the mask body part can also adopt different structures. For example, when the requirement for filterability is not high, a filter layer may be omitted, or a filter layer with better air permeability may be used to increase the water vapor discharge rate, where both the surface layer and other layers perform filtration. When the indoor use, or when using in non-inflammatory hot weather, the hygroscopic property of close skin layer is enough to provide comfortable body and feels, can omit the hygroscopic layer, because remains certain space between filter layer and the close skin layer, steam can remain here. In this case, it is preferable to use a hydrophobic material on the side of the skin-friendly layer adjacent to the filter layer, or to coat a hydrophobic coating layer so that water is less likely to permeate back through the skin-friendly layer. Under the using condition of the simple disposable mask or the condition of low requirement on the moisture absorption effect, only the surface layer, the filter layer and the skin-friendly layer are arranged, so that the comfortable effect can be realized to a certain degree, and the cost is reduced. For the mask with the breather valve, although the valve can discharge water vapor to a certain extent, according to the actual use experience, because the mask is generally higher in filtering performance, for example, the mask conforms to the KN95 type, liquid drops can still remain on the inner surface of the mask after long-term use, so that the mouth, nose and face are damp and hot, discomfort can be greatly reduced by using the technical scheme of the invention, and the wearing experience of lasting dryness and comfort is provided.
When the mask structure is suitable for different mask types, the mask structure can be adjusted correspondingly according to the mask types, for example, a multi-layer folding structure is required to be arranged on a mask body of a folding type mask, all layers can be folded simultaneously and unfolded during use, and at the moment, all layers of materials which are softer and resistant to bending are preferably used. To having valve class gauze mask, the valve can form the design of lining up on each layer structure of gauze mask, perhaps preferred close skin layer can set up in breather valve inboard and cover the valve, improves and feels the comfort level. For an integrated mask or a mask without multi-layer folding, materials with stronger support can be used as materials of all layers such as moisture absorption and filtration, and good skin-friendly and water absorption performances are provided. Meanwhile, auxiliary devices such as a nose clip and the like can be arranged on the outer side of the mask according to needs. Therefore, the mask of the present invention is not particularly limited in its shape, and the technical solution of the present invention can be applied to various conventional masks and specific types of masks. Meanwhile, the thickness of each layer of the mask, the aperture of the fabric fiber, the weaving mode, the sealing mode and the assembling mode can be set according to actual use requirements.
The invention has the beneficial effects that: through the skin-friendly layer that uses skin-friendly moisture absorption material to constitute at gauze mask internal surface, realize the absorption filtration to facial heat and steam, provide dry and comfortable experience for the user. Through set up the moisture absorption layer in close skin layer outside, the reinforcing is to the absorption of steam, reduce the facial moist stifled gauze mask that leads to because of reasons such as weather swelter and wear uncomfortable sense, provide lasting nice and cool dry comfortable impression, the wish is worn to reinforcing user's gauze mask, and can be stricter wear the gauze mask according to the standard, reduce the harm of pollution and germ propagation to the human body, especially during epidemic situation outbreak on a large scale, more effective general public of guarantee and medical personnel's is healthy. Particularly, people who need to wear the mask for a long time such as the respiratory sleep syndrome can also be provided with more comfortable experience. In addition to the above beneficial effects, the unexpected technical effects of the present invention include that in winter or in low temperature environment, when wearing the mask and the glasses at the same time due to temperature difference, water mist is formed on the glasses by water vapor leaked from the upper part of the mask, which disturbs the sight, even if the mask is sealed by nose clips, discomfort is increased by over-tight fixation, and when using the mask structure of the present invention, the provided high efficiency moisture absorption effect can effectively alleviate the water vapor condensation on the glasses surface under low temperature condition.
