Abstract
Description
Technical Field
[0001] The utility model relates to a breathing mask, in particular to a breathing mask with an annular comfort layer. The breathing mask is suitable for accommodating a part of a user's face to prevent leakage of pressurized gas supplied to the user. Background Art
[0002] Obstructive Sleep Apnea (OSA) is a common sleep breathing disorder that affects approximately 4% of men and 2% of women worldwide. It is characterized by repeated partial or complete pauses in the patient's breathing during sleep, with each pause lasting more than 10 seconds, which can occur dozens or even hundreds of times in one night. This pause is caused by the repeated collapse of the patient's upper airway during sleep. Each collapse causes a decrease in blood oxygen saturation and may trigger a series of physiological and psychological reactions, including wakefulness, tachycardia, cardiovascular disease, daytime sleepiness, neurasthenia, etc. If not treated in time, it may have a serious impact on the patient's health and quality of life.
[0003] One of the common treatments for OSA is the use of continuous positive airway pressure (CPAP). CPAP continuously delivers positive pressure air to the patient's upper airway through a mask to keep the patient's upper airway open and prevent the patient's upper airway from collapsing during sleep. CPAP therapy has been shown to have significant effects on improving patients' blood oxygen saturation, reducing daytime sleepiness, and improving cognitive function. However, although the efficacy of CPAP has been widely recognized, its compliance is not ideal. According to studies, about 50% of patients give up using CPAP within 6 months after receiving CPAP treatment. The mask is a key part of CPAP treatment because it is the part of the device that contacts the patient, and its comfort directly affects the patient's acceptance of the treatment. However, there are many problems with the design of traditional CPAP masks, including discomfort, poor sealing, and facial pressure sores, all of which affect patients' acceptance and compliance with CPAP treatment.
[0004] First of all, comfort is one of the main concerns of patients about masks. Since the mask needs to fit tightly against the user's face to achieve a sealing effect, excessive pressure often makes the patient feel uncomfortable. Especially after wearing it for a long time, the mask may exert excessive pressure on the user's nose bridge, cheeks, forehead and other parts, causing redness, swelling, pain, bruises and other problems.
[0005] Secondly, sealing is also an important consideration in mask design. A good mask design should be able to provide comfort while maintaining good sealing to avoid gas leakage. However, the shape and size of the face vary from person to person, making it difficult to achieve an ideal sealing of the mask. In many cases, the mask cannot fit the face completely, resulting in air leakage and affecting the treatment effect.
[0006] In order to increase the sealing effect, the user can only apply pressure to the mask by tightening the headband and other means to achieve the sealing effect, but the sealing surface of the mask is not flat, and tightening the headband will bring different pressures to different areas of the face. When the mask is sufficiently sealed, the user may not be able to tolerate wearing it for a long time. In addition, the material of the sealing surface of traditional masks is not breathable. Continuously wearing a tight mask for a long time may cause skin irritation or redness. In addition, if the user has oil and sweat on the face during sleep, the sealing performance of the mask will be reduced. These problems not only make patients feel uncomfortable, but may even cause patients to give up using it. At the same time, constantly adjusting the position of the mask to alleviate discomfort may lead to a decrease in sealing and affect the treatment effect.
[0007] In order to improve these problems, many improved mask designs have been proposed. For example, mask pads are being sold on the market, and masks are made of softer materials. However, although these designs have improved the comfort and sealing of the mask to a certain extent, there are still some problems. For example, the use of pads can reduce pressure sores caused by close contact between the mask and the skin, but during sleep, the head, facial bones and muscles will move to a certain extent, so the pads may shift or fall off during treatment, resulting in poor sealing; using softer materials may cause the structure of the mask to be unstable, affecting the sealing.

[0044] The breathing mask with good sealing and comfort of the utility model can at least achieve the following beneficial effects:
[0045] The utility model sets the surface of the breathing mask contacting the user in the form of a combination of an annular comfort layer and an elastic member to replace the prior art, wherein the first surface of the annular comfort layer seals at least a part of the user's face, and the second surface covers at least a part of the elastic member. By changing the material covering the face, the comfort and sealing performance of the breathing mask are improved. Such a design has several advantages.
[0046] First, the combination of the elastic part and the annular comfort layer allows the respiratory mask to deform to different degrees in different areas of the face, fit the facial contour better, and seal better. In addition, the elastic part and the annular comfort layer contact the face together to distribute the uneven pressure on the face caused by tightening the headband, reduce the red marks and pressure sores on the face caused by the mask pressure, and provide higher comfort.
[0047] In addition, the movement of the user's head during sleep and the sweating and oily face will affect the mask. The annular comfort layer has good air permeability and can absorb facial sweat and oil, which can keep the user's face dry, reduce the possibility of mask displacement or weakening of sealing performance, and ensure the sealing of the mask.
[0048] It is worth mentioning that there are other products on the market that use foam (annular comfort layer) on masks to achieve high comfort and good sealing. However, in order to conform to the face, the foam in the nose area of this product is made thinner than other areas, and has a larger overhang, which is easy to cause tearing and damage, so that the mask cannot be properly sealed. The breathing mask provided by the utility model combines the sealing surface structure elastic parts and the annular comfort layer. The elastic parts are used to shape different wall thicknesses in the nose area so that it fits the bridge of the nose to achieve a sealing effect, and other relatively flat parts of the face are sealed by the annular comfort layer. Elastic materials are used to seal the easily damaged nose area, which is more durable and has a longer service life; the annular comfort layer is used to seal the relatively flat and less undulating areas of the cheeks and chin, which is not easy to tear. This can maximize the sealing and comfort of use, and also increase the service life of the breathing mask.
[0049] Moreover, the breathing mask of the utility model is more environmentally friendly than the masks with foam materials in the prior art. The masks in the prior art achieve sealing and therapeutic effects by bonding foam materials with face shapes to flat silicone. In this case, it is necessary to produce a flat elastic part separately to adapt to the foam material. However, the breathing mask of the utility model can still achieve effective sealing on the face when using a separate elastic part, that is, the same elastic part has two different forms (with an annular comfort layer and without an annular comfort layer) that can ensure sealing and therapeutic effects. Therefore, the utility model innovatively adopts a modular design of the mask, and the same elastic part brings two different use effects. Compared with the prior art that needs to produce separately matched elastic parts, it not only saves energy and raw materials, but is also more environmentally friendly.

[0070] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.
[0071] The utility model aims to solve the problems that the elastic part of the traditional breathing mask that fits the user's face adopts airtight materials such as silicone, and the local pressure on the user's face is too large when the elastic part fits the face to ensure the sealing during use, thereby causing red marks and pressure sores; and the problem that the mask with foam material in the prior art is easy to be damaged and the cushion is easy to slide and fall off. The utility model provides a breathing mask with an annular comfort layer, and the sealing surface that fits the user's face is constructed to consist of two parts, an elastic part and an annular comfort layer, so that the sealing surface is an elastic part at least in the part that contacts the user's nose bridge to avoid air leakage around the nose bridge, and contacts with the remaining parts through the annular comfort layer, so as to share the force exerted by the breathing mask on the user's face when the headband is tightened, so that the force on the user's face is even, thereby improving the user's experience of wearing the breathing mask.
[0072] The following describes several structures of the breathing mask with good sealing performance and comfort of the utility model in combination with specific examples.
[0073] Example 1
[0074] The breathing mask with good sealing and comfort of the utility model is configured to surround the user's nose and mouth and form a sealing area between the lower lip area and the nose bridge area, or surround the user's nose and form a sealing area between the upper lip area and the nose bridge area. In other words, the breathing mask of the utility model can be designed to be a small size that only covers the user's nose and provides pressurized breathing gas to the user's airway through the user's nasal cavity, or it can be designed to be a large size that covers the user's nose and mouth at the same time and provides pressurized breathing gas to the user's airway through the user's nasal cavity and oral cavity, thereby meeting the needs of users with different usage habits and physiological conditions.
[0075] Please contact us for details. Figures 1 to 4 as well as Fig. 9The breathing mask 1 of this embodiment includes a rigid member 2, an elastic member 3, and an annular comfort layer 4. The breathing mask 1 includes a nose area and a mouth area corresponding to the user's face. Among them, the rigid member 2 can be made of any rigid material that can ensure the strength and support of the rigid member. For example, in this embodiment, the rigid member 3 is made of plastic material (PC material, PA material, ABS material). The color of the rigid member 2 can be transparent, translucent, or opaque. Preferably, the transparent color that allows the user's usage to be observed is used, followed by the translucent color. At least one gas delivery interface 21 is provided on the side of the rigid member 2 away from the user's face, which is used to receive the pressurized gas generated by the continuous positive airway pressure device. The gas delivery interface 21 can also be used to accommodate a frame or a joint connected to the continuous positive airway pressure device. An annular interface is provided on the side of the rigid member adjacent to the user's face, and a joint 22 is formed on the outer edge of the annular interface, which is connected to the elastic member 3 to fix the contour shape of the elastic member 3 and provide certain support for the elastic member 3.
[0076] The elastic member 3 is provided with a first accommodating area for accommodating the user's mouth and nose or nose and communicating with the inner cavity of the rigid member. The side of the elastic member 3 adjacent to the rigid member 2 is fixedly connected to the joint portion 22. The connection method between the elastic member 3 and the joint portion 22 of the rigid member 2 can be injection molding, or chemical bonding can be formed by a later adhesive, or it can be connected in the form of a clip or a buckle. The side of the elastic member 3 facing away from the rigid member 2 is provided with a pressing portion that seals at least a part of the user's nose. The pressing portion contacts at least a part of the user's nose, such as the bridge of the nose, the wing of the nose or the side wall of the nose, or it can be a combination of several parts. The same side of the elastic member 3 and the pressing portion is used to connect with the annular comfort layer 4. The elastic member 3 is configured to adjust the distance between the rigid member 2 and the face. In order to ensure that the elastic member 3 fits the face with enough deformation space during use and avoid the rigid member 2 directly applying pressure to the face when the user tightens the headband, the height between the edge of the elastic member 3 adjacent to the pressing portion and the edge of the elastic member 3 adjacent to the joint portion 22 is at least 8mm. Different areas of the elastic member 3 may have different heights, and the height may be in the range of 8-40 mm. In the present embodiment, the elastic member 3 is an airtight material and is made of a soft material with a certain deformation ability, for example, the elastic member 3 is made of silicone, rubber, thermoplastic elastomer or silicone resin material. More specifically, the elastic member 3 is made of silicone material. In addition, the side of the elastic member 3 facing away from the rigid member 2 has a non-thin area (excluding the part other than the thin area) and at least one thin area 33, and the wall thickness of the thin area 33 is in the range of 0.2-2 mm. The thin area corresponds to at least one area of the user's nose area 31 or the mouth area 43. The purpose of such a design is to enable the thin area 33 to fit closely to the user's face under the action of the treatment pressure to form a good sealing effect. The connection between the thin area 33 and the non-thin area can be smooth and coherent (slowly changing without visible traces to the naked eye) or abrupt (with a visible dividing line to the naked eye). In this embodiment, both the thin area 33 and the non-thin area are at least partially in contact with the user's face, and the thickness of at least the portion of the thin area in contact with the user's face is 7%-60% of the thickness of the portion of the non-thin area in contact with the user's face. In another form, the thin area 33 is completely in contact with the user's face, and the non-thin area does not directly contact the user's face.
[0077] The annular comfort layer 4 is configured to seal at least a portion of the user's face when in use. A second accommodation area for accommodating the user's mouth or nose and communicating with the first accommodation area is provided in the annular comfort layer 4. The annular comfort layer 4 is fixedly connected to a surface of the elastic member 3 facing away from the rigid member 2 and covers at least a portion of the pressing portion. The annular comfort layer 4 and the elastic member 3 together form a sealing surface (such as a sealing surface) in contact with the user's face. Figure 3As shown). The elastic member 3 is connected to the annular comfort layer 4 in a non-detachable manner. In some forms, the connection between the annular comfort layer 4 and the elastic member 3 is detachable. In this embodiment, the elastic member 3 and the annular comfort layer 2 are connected by molding, hot pressing, welding, foaming, and adhesive. In some forms, the elastic member 3 and the annular comfort layer 2 are indirectly connected by an auxiliary material as a sandwich. In another form, the elastic member 3 and the annular comfort layer 2 can also be connected by auxiliary accessories, such as clips and belts. The material of the annular comfort layer 4 is a composite material of two or more, such as a composite of any material in a foam material, a textile material, a new absorbent material or other biocompatible materials. In some forms, the annular comfort layer 4 can also be a single material. There are also many ways of compounding, such as glue compounding (compounding different materials by viscose), flame compounding (by heating, melting the material, and relying on its own viscosity to bond different materials). In this embodiment, the annular comfort layer 4 is made of foam material, specifically, the annular comfort layer 4 is made of polyurethane, low-density polyether or EVA material. Furthermore, the annular comfort layer 4 has a three-dimensional shape and a density ranging from 10 to 200 kg / m 3 In order not to affect the treatment effect, the permeability of the annular comfort layer 4 is less than 50L / min.
[0078] It should be noted that the annular comfort layer 4 and the elastic member 3 together form a sealing surface for the user's face to contact in order to solve the problem that the breathing mask in the prior art uses silicone or similar airtight materials to fit the face and seal, and the user often feels uncomfortable and has red marks and pressure sores on the face due to long-term wearing and compression. In addition, due to the airtight characteristics of the material, the user's face sweats and produces oil during use, which will cause the head to move during sleep and pull the mask, thereby causing the mask to shift or weaken the sealing performance. Therefore, the utility model constructs the sealing surface as an annular comfort layer 4 and an elastic member 3. At least a part of the elastic member 3 that contacts the user's nose is retained in the nose area, and the other sealing surfaces are all annular comfort layers 4. Because the annular comfort layer 4 has better deformation ability than the elastic member 3, it can share the uneven pressure on the face caused by tightening the headband, so that the user has a more comfortable experience. The annular comfort layer 4 has good air permeability, can absorb facial sweat and grease, keep the user's face dry, reduce the possibility of displacement of the mask, and ensure the sealing of the mask. Compared with the existing breathing masks whose sealing surface is completely made of foam, in order to achieve a good seal and user experience at the bridge of the nose, the foam is made thinner than other areas and has a larger overhang, which will cause the nose area of the face to be squeezed during use, causing tearing and damage. At the same time, there is a large height difference between the bridge of the nose and the facial area, so leakage is very likely to occur in the nasal area. However, the breathing mask 1 in the utility model still uses an airtight elastic member 3 in the nose area, so there will be no leakage; the annular comfort layer 4 is used to fit the relatively flat areas of the cheeks and chin, which has less undulations and is not easy to tear, so that the sealing and comfort of use can be guaranteed to the greatest extent.
[0079] Please combine Figure 1 , Figure 5 , Figure 6 The annular comfort layer 4 has an annular profile (a continuous shape connected end to end), and the inner edge of the annular comfort layer 4 can surround the user's nose or mouth and nose. In order to achieve the elastic member 3 and the annular comfort layer 4 to seal the user's face at the same time, the inner edge 44 of the annular comfort layer 4 is greater than or equal to the inner edge 32 of the elastic member 3 adjacent to the pressing portion. Figure 6As shown, the cross-sectional shape of the annular comfort layer 4 is a triangle, a quadrilateral, a pentagon or a hexagon. The annular comfort layer 4 includes a first surface 41 that contacts the user's face and a second surface 42 connected to the elastic member 3. Generally speaking, the first surface 41 roughly fits the shape of the face when in use, and in order to improve comfort, the edge of the first surface 41 is rounded. The second surface 42 is roughly a plane. When connected to the elastic member 3, the shape of the second surface 42 is adapted to the shape of the side of the elastic member 3 adjacent to the pressing portion. For comfort considerations, the first surface 41 should conform to the general contour trend of the face. The first surface 41 and the second surface 42 can be parallel, or they can form a certain angle in accordance with the facial trend, such as Figure 6 The angles between the first surface 41 and the second surface 42 in different forms are shown. Specifically, the angle α between the first surface 41 and the second surface 42 of the annular comfort layer 4 is 0-80°. For a better user experience, it is necessary to avoid the height of the annular comfort layer 4 being too high, so as to avoid a step difference with the elastic member 3 when contacting the face, and it is necessary to ensure the width of the annular comfort layer 4 so that the annular comfort layer 4 can completely cover the area except the nose area 31 when the breathing mask 1 contacts the face. In this embodiment, the height of the annular comfort layer 4 is 1-30 mm, and the ratio of width to height is 0.1-30.
[0080] Please combine Figures 7 and 8 In order for the respiratory mask 1 to automatically fit the facial contours of most people during use and to ensure sealing and comfort, various areas of the respiratory mask 1 need to produce different degrees of deformation to adapt to the facial contours and the pressure generated at different positions on the face should be roughly uniform. When the mask in the utility model applies a constant force to different positions of the comfort layer in a constant direction (a direction perpendicular to the sagittal plane), the elastic part at the force point and the comfort layer will produce different degrees of deformation, that is, the same force is applied to different positions of the annular comfort layer 4 in a constant direction, and the distance change between the first surface 41 of the annular comfort layer 4 and the rigid part 2 will produce at least two different values. In this way, during the wearing process, the elastic part 3 and the annular comfort layer 4 can conform to the facial contours and produce different degrees of deformation, and the soft and elastic material can also disperse the pressure on the face to achieve a more comfortable wearing effect. In this embodiment, the height of the annular comfort layer 4 is uniform, and the changes of the annular comfort layer 4 when subjected to pressure are as follows: Figure 7 As shown in the figure, d1 and d2 are the deformation values of the first surface 41 of the annular comfort layer 4 before and after the force is applied, that is, the change value of the distance between the first surface 41 of the comfort layer 4 and the rigid member 3. In some forms, the height of the annular comfort layer 4 changes unevenly. When the annular comfort layer 4 is subjected to pressure, the change is as follows: Figure 8 shown.
[0081] Example 2
[0082] The breathing mask with good sealing and comfort of this embodiment is configured to surround the user's nose and mouth and form a sealing area between the lower lip and the bridge of the nose, or surround the user's nose and form a sealing area between the upper lip and the bridge of the nose, and supply pressurized breathing gas to the user's airway, including a rigid member 2, an elastic member 3, and an annular comfort layer 4. The breathing mask 1 provided in this embodiment is different from the breathing mask in embodiment 1 in that the material of the annular comfort layer 4 is different. Figures 10 to 12 As shown (the nose mask is not shown), the annular comfort layer 4 in this embodiment is made of at least one absorbent material. Specifically, the annular comfort layer 4 is made of foam material or textile material or a composite material of foam material and textile material. The foam material is polyurethane, low-density polyether, EVA, rubber foam, latex foam. The foam part further enhances the elasticity of the breathing mask 1, making it fit the face more closely, and the textile material enhances the water absorption of the annular comfort layer 4 of the foam material alone. The surface of the textile material is smoother and softer than that of the foam material, which is conducive to improving the user's sleep quality and treatment effect, and improving treatment compliance.
[0083] This embodiment can have three variations, one of which is as follows: Fig.10 As shown, the main part of the annular comfort layer 4 is a foam material, and the textile material as a wrapper completely covers the foam material, so that the first surface 41 of the annular comfort layer 4 that contacts the face is a textile material. The textile material completely wraps the foam material, reducing the possibility of tearing of the foam material and increasing the service life of the breathing mask 1. Fig.11 As shown, the textile material only covers the surface of the foam material on one side adjacent to the user's face. This design can not only prevent the foam from tearing, but also ensure the air permeability of the foam material. The foam material is partially exposed to the air environment, which can better volatilize the absorbed moisture and heat, thereby increasing the dryness and drying time of the annular comfort pad 4. Fig.12 As shown (the figure only shows that the textile material covers the upper part of the foam material, but it can actually cover other parts, for example, the textile material covers the lower part of the foam, that is, the textile material contacts the mouth area; for another example, the textile material covers the zygomatic bone area where the respiratory mask 1 contacts the more prominent facial contour bones.), the textile material covers a part of the foam material, that is, the foam material and the textile material contact the user's face at the same time.
[0084] Example 3
[0085] The breathing mask with good sealing and comfort of this embodiment is configured to surround the user's nose and mouth and form a sealing area between the lower lip and the bridge of the nose, or surround the user's nose and form a sealing area between the upper lip and the bridge of the nose, and supply pressurized breathing gas to the user's airway, including a rigid member 2, an elastic member 3, and an annular comfort layer 4. The breathing mask 1 provided in this embodiment is different from the breathing mask in embodiment 1 in that the material of the annular comfort layer 4 is different. Fig.13 As shown (the nose mask is not shown), in this embodiment, the annular comfort layer 4 is made of absorbent material, specifically, a textile material, and the textile material is nylon, spandex or polyester. More specifically, the annular comfort layer is made of a single-layer textile material, which is thinner and more breathable, and can provide a soft skin feel to the user while retaining the contour of the elastic member 3 adjacent to the pressing portion to the greatest extent, so as to better fit the user's face.
[0086] Example 4
[0087] The breathing mask with good sealing performance of this embodiment is configured to surround the user's nose and mouth and form a sealing area between the lower lip and the bridge of the nose, or surround the user's nose and form a sealing area between the upper lip and the bridge of the nose, and supply pressurized breathing gas to the user's airway, including a rigid member 2, an elastic member 3, and an annular comfort layer 4. The breathing mask 1 provided in this embodiment is different from the breathing mask in Example 1 in that the material of the annular comfort layer 4 is different. Fig.14 As shown (the nose mask is not shown), in this embodiment, the annular comfort layer 4 is made of absorbent material, specifically, made of textile material, and the textile material is nylon, spandex or polyester. More specifically, the annular comfort layer 4 is made of multiple layers of textile material (two or more layers), and each layer of textile material is a different type of material. The performance of the annular comfort layer 4 is improved by the combination of multiple layers of textile material, wherein the bottom layer of the multiple layers of textile material and the elastic member 3 can be made of airtight fabric to prevent the adhesive from penetrating into the first surface 41 of the annular comfort layer 4. In some forms, the bottom layer of fabric can also be covered with an airtight film to achieve the function of preventing penetration. Here is a simple example: for example, a combination of three layers of textile material, a layer adjacent to the user's face is made of highly elastic, light and hygroscopic spandex fabric; the middle layer is also hygroscopic, but not as comfortable as spandex fabric. The nylon fabric absorbs the oil and sweat on the face; the bottom layer is made of fabric made of polyester to prevent the adhesive from penetrating. In other forms, other combinations of fabrics of different types and layers can also be used. In another form, the multiple layers of textile material may also be a mixture of the same material, by stacking the same single layer of textile material to increase the thickness of the comfort layer and make the user feel softer.
[0088] Example 5
[0089] The breathing mask with good sealing performance of this embodiment is configured to surround the user's nose and mouth and form a sealing area between the lower lip and the bridge of the nose area, or surround the user's nose and form a sealing area between the upper lip area and the bridge of the nose area, and supply pressurized breathing gas to the user's airway, including a rigid part 2, an elastic part 3, and an annular comfort layer 4. The difference between the breathing mask 1 provided in this embodiment and the breathing mask in Example 1 is that the material of the annular comfort layer 4 is different. In this embodiment, the annular comfort layer 4 uses a textile material containing a phase change material (PCM for short). The PCM can absorb or release heat during the phase change process. The heat is absorbed by the endothermic phase change material, and the heat is released by the exothermic phase change material. The phase change of the phase change material is reversible, so it can be used to adjust the temperature of the annular comfort layer 4, so that the annular comfort layer 4 can maintain a suitable body temperature when it contacts the user's face in different environments.
[0090] There is another implementation form of this embodiment, that is, the annular comfort layer 4 contacts the user's face alone. At this time, the respiratory mask 1 includes a rigid part 2, and at least one gas delivery interface 21 is provided on the side of the rigid part 2 away from the user's face, and an annular interface is provided on the side of the rigid part 2 adjacent to the user's face, and a joint 22 is formed on the outer edge of the annular interface; an elastic part 3, wherein a first accommodating area for accommodating the user's mouth, nose or nose and communicating with the inner cavity of the rigid part is provided in the elastic part 3, and a side of the elastic part 3 adjacent to the rigid part is fixedly connected to the joint 22, and a side of the elastic part 3 facing away from the rigid part is used to connect the annular comfort layer 4; the annular comfort layer 4 is configured to seal the user's face when in use, and a second accommodating area for accommodating the user's mouth, nose or nose and communicating with the first accommodating area is provided in the annular comfort layer 4, and the annular comfort layer 4 is fixedly connected and covers at least part of the side of the elastic part facing away from the rigid part, and the annular comfort layer 4 includes a phase change material.
[0091] Example 6
[0092] The breathing mask with good sealing performance of the present embodiment is configured to surround the user's nose and mouth and form a sealing area between the lower lip and the bridge of the nose area, or surround the user's nose and form a sealing area between the upper lip area and the bridge of the nose area, and supply pressurized breathing gas to the user's airway, including a rigid member 2, an elastic member 3, and an annular comfort layer 4. The difference between the breathing mask 1 provided in this embodiment and the breathing mask in Example 1 is that the material of the annular comfort layer 4 is different. In this embodiment, the annular comfort layer 4 adopts a composite material with added graphene fiber. Graphene has excellent thermal conductivity and can quickly conduct away the heat inside the annular comfort layer 4, reducing the user's feeling of stuffiness during use. In addition, the antibacterial property of graphene can also reduce the growth of bacteria during the use of the mask and keep the mask clean.
[0093] There is another implementation form of this embodiment, that is, the annular comfort layer 4 contacts the user's face alone. At this time, the respiratory mask 1 includes a rigid member 2, and at least one gas delivery interface 21 is provided on the side of the rigid member 2 away from the user's face, and an annular interface is provided on the side of the rigid member 2 adjacent to the user's face, and a joint 22 is formed on the outer edge of the annular interface; an elastic member 3, wherein a first accommodating area for accommodating the user's mouth, nose or nose and communicating with the inner cavity of the rigid member is provided in the elastic member 3, and a side of the elastic member 3 adjacent to the rigid member is fixedly connected to the joint 22, and a side of the elastic member 3 facing away from the rigid member is used to connect the annular comfort layer 4; the annular comfort layer 4 is configured to seal the user's face when in use, and a second accommodating area for accommodating the user's mouth, nose or nose and communicating with the first accommodating area is provided in the annular comfort layer 4, and the annular comfort layer 4 is fixedly connected and covers at least part of the side of the elastic member facing away from the rigid member, and the annular comfort layer 4 includes graphene.
[0094] Example 7
[0095] The breathing mask with good sealing performance of this embodiment is configured to surround the user's nose and mouth and form a sealing area between the lower lip and the bridge of the nose area, or surround the user's nose and form a sealing area between the upper lip area and the bridge of the nose area, and supply pressurized breathing gas to the user's airway, including a rigid member 2, an elastic member 3, and an annular comfort layer 4. The difference between the breathing mask 1 provided in this embodiment and the breathing mask in Example 1 is that the material of the annular comfort layer 4 is different. In this embodiment, the annular comfort layer 4 uses a composite material containing an antibacterial agent, such as silver chloride or some extracts of natural fabrics (tea tree oil, olive leaf extract, lavender oil). Antibacterial agents can effectively inhibit the growth of bacteria and reduce the risk of infection during the use of the mask. In addition, the addition of antibacterial agents can also extend the service life of the breathing mask 1 and reduce the frequency of users replacing the breathing mask 1. In some forms, antibacterial fibers, such as silver fibers and copper fibers, can also be added to the annular comfort layer 4 to achieve an antibacterial effect.
[0096] There is another implementation form of this embodiment, that is, the annular comfort layer 4 contacts the user's face alone. At this time, the respiratory mask 1 includes a rigid part 2, and at least one gas delivery interface 21 is provided on the side of the rigid part 2 away from the user's face, and an annular interface is provided on the side of the rigid part 2 adjacent to the user's face, and a joint 22 is formed on the outer edge of the annular interface; an elastic part 3, wherein a first accommodating area for accommodating the user's mouth, nose or nose and communicating with the inner cavity of the rigid part is provided in the elastic part 3, and a side of the elastic part 3 adjacent to the rigid part is fixedly connected to the joint 22, and a side of the elastic part 3 facing away from the rigid part is used to connect the annular comfort layer 4; the annular comfort layer 4 is configured to seal the user's face when in use, and a second accommodating area for accommodating the user's mouth, nose or nose and communicating with the first accommodating area is provided in the annular comfort layer 4, and the annular comfort layer 4 is fixedly connected and covers at least part of the side of the elastic part facing away from the rigid part, and the annular comfort layer 4 includes a composite material containing an antibacterial agent.
[0097] The breathing mask with good sealing performance of the utility model can at least achieve the following beneficial effects:
[0098] 1) The combination of the elastic member 3 and the annular comfort layer 4 can make the breathing mask 1 conform to different degrees of deformation in different areas of the face, fit the facial contour better, and have better sealing. In addition, the elastic member 3 and the annular comfort layer 4 contact the face together to distribute the uneven pressure on the face caused by tightening the headband, reduce the red marks and pressure sores on the face caused by the mask pressure, and provide higher comfort.
[0099] 2) During sleep, the user's head moves and the face sweats and oils, which will affect the mask. The annular comfort layer 4 has good air permeability and can absorb sweat and oil on the face at night, so that the user's face can stay dry, reduce the possibility of displacement of the mask or weakening of the sealing performance, and ensure the sealing of the mask.
[0100] 3) Elastic material is used in the nose area which is easily damaged, which is more durable and has a longer service life; an annular comfort layer 4 is used in the relatively flat and less undulating areas of the cheeks and chin, which is not easy to tear, so that the sealing and comfort of use can be guaranteed to the greatest extent, and the service life of the breathing mask 1 is increased.
[0101] 4) The utility model innovatively adopts a modular mask design. The same elastic member 3 has two different forms (with and without an annular comfort layer) that can ensure sealing and treatment effects, which not only saves energy and raw materials, but is also more environmentally friendly.
[0102] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
