[0029] The embodiments of the present disclosure will be described in detail below with reference to the drawings.

[0030] The embodiments of the present disclosure will be described in detail below with reference to the drawings.

[0031] It should be apparent that the described embodiments are only some - but not all - of implementing the present disclosure. The present disclosure can be carried out or implemented in other different ways, and the details in the present disclosure can be modified or changed based on different views and applications without departing from the spirit of the present disclosure. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present disclosure.

[0032] It is also necessary to note that the drawings provided in the following embodiments only illustrate the basic concept of the present disclosure in a schematic manner, and only the components related to the present disclosure are shown in the drawings, not the number, shape and size of the components when actually implemented. The actual implementation of each component may be a random change in number, shape and size, and the component layout may also be more complex.

[0033] In addition, in the following description, specific details are provided in order to facilitate a thorough understanding of the examples. However, one skilled in the art will understand that the aspects described can be practiced without these specific details.

[0034] As Figure 1 The composite fixing device for enhancing the nasal congestion fixation and comfort of CPAP includes a flexible nose pad 1, an adjustable headband 2, a face dressing pad 3, a side wing support 4, a nose bridge support 5, and a male and female buckle 6.

[0035] The flexible nose pad 1 is the core component of the device, which is designed according to the ergonomic principle and perfectly fits the user's nasal cavity structure. The flexible nose pad 1 is made of flexible medical-grade material, which has good ductility and durability, and can provide a comfortable wearing experience while ensuring a tight seal. Through this design, the flexible nose pad 1 not only provides preliminary support and sealing effect for nasal congestion, but also effectively reduces skin irritation and pressure marks caused by long-term wear.

[0036] The adjustable headband 2 is an important part of the fixing device, one end of which is fixed to the flexible nose pad 1, and the other end is connected through an adjustable buckle. The adjustable headband 2 is usually made of soft but elastic material, which can be flexibly adjusted according to the size of the user's head. Through this adjustment mechanism, users can easily find the most appropriate wearing tightness to ensure the stability of the device and prevent it from loosening or falling off during use.

[0037] The face dressing pad 3 is fixed at the middle position of the adjustable headband 2, which directly contacts the user's face, increasing the stability and comfort of the device. The pad 3 is made of high-density foam or other soft materials, which has good moisture absorption and ventilation, and can reduce the discomfort of long-term wear. In this way, the face dressing pad 3 not only provides additional support, but also prevents air leakage, further improving the sealing performance of the overall device.

[0038] The side wing support 4 is installed on both sides of the flexible nose pad 1 and extends backward through the flexible material to the adjustable headband 2. The side wing support 4 serves to distribute pressure and provide additional fixing points, thereby further enhancing the stability and reliability of the entire device. This design ensures that the device will not easily shift even when the user's head moves significantly, improving user experience.

[0039] The nose bridge support 5 is embedded in the upper part of the flexible nose pad 1, designed along the contour of the nose bridge, playing a key role in strengthening the stability and sealing effect of the nasal plug. The nose bridge support 5 is usually made of hard material and fixed inside the flexible nose pad 1 by embedding. This design can effectively improve the fit between the nasal plug and the nose bridge, reduce air leakage, and at the same time avoid excessive compression on the nose bridge, maintaining the comfort of long-term wear.

[0040] The male and female buckles 6 are used to fix the adjustable headband 2 with the facial dressing pad 3, ensuring the tight connection of the entire device during use. The male and female buckles 6 are composed of two interlocking parts, one part is sewn or pasted on the adjustable headband 2, and the other part is fixed on the facial dressing pad 3. This connection method is simple and reliable, easy to adjust and remove quickly, and at the same time ensures the overall stability of the device.

[0041] Specifically, the flexible nose pad 1 can be manufactured by injection molding, and the material can be soft silicone or TPE (thermoplastic elastomer) to ensure good flexibility and biocompatibility. The adjustable headband 2 can be realized by elastic webbing combined with plastic buckles to ensure the flexibility and stability of adjustment. The facial dressing pad 3 can choose a double-layer structure, the outer layer uses breathable cloth, and the inner layer fills high-density foam to provide the best fit and breathability. The side wing support 4 can be made by injection molding and fixed between the flexible nose pad 1 and the adjustable headband 2 by thermoplastic material to realize seamless connection. The nose bridge support 5 can be made of stainless steel wire or other lightweight metal materials, embedded inside the flexible nose pad 1 and fixed by secondary vulcanization process. The male and female buckles 6 can be realized by mature magic tape materials on the market to ensure firm connection and convenient adjustment.

[0042] Through the above technical means, the invention solves the problem of unstable fixation and patient discomfort caused by the use of CPAP nasal plug fixation with binding tape. The traditional binding tape fixation method cannot evenly distribute pressure, which easily causes local compression and air leakage, seriously affecting user experience. The application of multiple fixation structures and flexible materials in this invention ensures that the device can evenly distribute pressure on the user's face when worn, improving the stability and sealing effect of the device. Especially in the process of long-term use, this device can significantly reduce the discomfort of patients, enhance the effectiveness and comfort of treatment.

[0043] In one embodiment, the flexible nose pad 1 of the composite fixing device for enhancing CPAP nasal congestion fixation and comfort of the present application is composed of multiple layers of different materials. The innermost layer is a skin-friendly material layer, which provides softness and comfort when directly contacting the user's skin, reducing discomfort or skin irritation that may be caused by long-term wear. The middle layer is a memory foam layer, which has good deformation and recovery ability, and can naturally fit the user's nasal cavity contour, increasing the stability and airtightness during wearing. The outermost layer is a bacteria-resistant material layer, which aims to effectively resist the growth and spread of bacteria and maintain cleanliness and hygiene.

[0044] To achieve the above features, the layers of materials are tightly connected together by adhesion or other suitable means. For example, the skin-friendly material layer can be fixed with the memory foam layer by adhesive or other connection means, ensuring that there is no gap between the two. Similarly, the memory foam layer is also firmly connected with the bacteria-resistant material layer, forming an integral flexible nose pad 1. This multi-layer structure design makes the flexible nose pad 1 not only have good physical properties, but also meet the hygiene needs.

[0045] In one embodiment, the adjustable headband 2 of the composite fixing device for enhancing CPAP nasal congestion fixation and comfort of the present application is provided with multiple elastic regions 7, the positions and lengths of which can be adjusted according to the specific needs of the user to ensure that the device can still be firmly fixed on the user's head in different motion states. The adjustable headband 2 is mainly made of flexible material to ensure comfort and softness. The multiple elastic regions 7 are embedded in the adjustable headband 2, each of which is made of high-elasticity material such as rubber or nylon elastic yarn, so that it can effectively stretch and recover to the original state. The lengths of these elastic regions 7 can be cut or increased according to the user's head size and motion needs, in order to provide personalized fixing solutions for the user.

[0046] Specifically, each elastic region 7 is firmly fixed inside the adjustable headband 2 by sewing or adhesion, ensuring that it will not come off during use. In addition, the design of the elastic region 7 also takes into account the uniform stress of the headband, so that the user will not feel any discomfort when wearing. For example, if the user needs higher fixing stability, the number and length of the elastic regions 7 can be increased; if the user has higher requirements for comfort, shorter and evenly distributed elastic regions 7 can be selected to reduce the pressure on the head. The positions and lengths of these elastic regions 7 can be adjusted in a user-defined manner, such as using adjustment buckles or adhesive strips and other components, so that the user can conveniently make personalized settings.

[0047] In one embodiment, as shown in FIG. 6, the adjustable headband 2 of the composite fixing device for enhancing CPAP nasal congestion fixation and comfort of the present application is provided with multiple elastic regions 7, the positions and lengths of which can be adjusted according to the specific needs of the user to ensure that the device can still be firmly fixed on the user's head in different motion states. The adjustable headband 2 is mainly made of flexible material to ensure comfort and softness. The multiple elastic regions 7 are embedded in the adjustable headband 2, each of which is made of high-elasticity material such as rubber or nylon elastic yarn, so that it can effectively stretch and recover to the original state. The lengths of these elastic regions 7 can be cut or increased according to the user's head size and motion needs, in order to provide personalized fixing solutions for the user. Figure 1As shown, the facial dressing pad 3 of a composite fixation device for enhancing the fixation and comfort of CPAP nasal plugs according to this application includes a removable pad 8. This pad 8 can be replaced or customized according to the user's facial features to improve fit and comfort. The pad 8 is installed at the location where the device contacts the user's face, specifically between the CPAP nasal plug and the user's nose. The pad 8 is made of a soft material to reduce pressure on the skin while ensuring good airtightness.

[0048] The removable pad 8 is designed for easy replacement or cleaning. The pad 8 is attached to the facial dressing body via a convenient connection method, such as adhesive, clips, or Velcro. Users can choose pads 8 of different shapes and thicknesses to suit their facial contours, achieving a more personalized fit. This design not only improves the versatility and comfort of the device but also extends its overall lifespan, reducing the need for frequent replacements.

[0049] For example, if a user finds that the fit in a certain area is insufficient during use, they can replace it with a pad 8 of the corresponding shape. Specifically, the edges of the pad 8 can be designed with a wavy or textured shape to better conform to the curves of the face while ensuring no air leakage. In this way, the pad 8 not only provides excellent sealing performance but also significantly improves the user's wearing experience.

[0050] In one embodiment, such as Figure 2 As shown, the side wing bracket 4 of the composite fixation device for enhancing the fixation and comfort of CPAP nasal plugs in this application has a metal wire 9 embedded inside. This metal wire 9 can be finely adjusted according to the user's head shape. The material of the side wing bracket 4 is typically a soft and elastic material, such as silicone or flexible plastic, to ensure wearing comfort and fit. The metal wire 9, embedded inside the side wing bracket 4, provides additional support and adjustability. Through different head shapes and pressure distributions, the metal wire 9 can adapt to different head contours, allowing the side wing bracket 4 to distribute pressure more evenly and increase fixation stability.

[0051] Specifically, the metal wire 9 can be embedded into the side wing support 4 through injection molding or other embedding processes, ensuring a tight fit between the metal wire 9 and the side wing support 4 and preventing the metal wire 9 from being exposed and causing discomfort. One end of the metal wire 9 can have some free movement at one end of the side wing support 4, allowing the user to manually adjust its bending degree as needed. This structural design allows the metal wire 9 to not only provide stable support when fixing the nasal plug, but also to be finely adjusted according to changes in the user's head shape, thereby improving the overall comfort and stability of the device. For example, in practical applications, the user can gently press and bend the metal wire 9 to make it fit the forehead and temples more closely, thus better adapting to different facial structures.

[0052] Referring back Figure 1 In one embodiment, the nose bridge support 5 of the composite fixing device for enhancing CPAP nasal congestion fixation and comfort has an adjustable height design. This feature of the nose bridge support 5 allows users to select the appropriate fixing position according to their own nose bridge height, thereby optimizing the fitting effect of the nasal congestion device. The nose bridge support 5 is closely fitted to the user's nose bridge contour through the setting at the nose bridge position, thereby improving the overall stability and comfort of the fixing device. Multiple adjustment holes 10 are distributed along the length direction of the nose bridge support 5, and users can adjust the height position of the nose bridge support 5 by selecting different adjustment holes 10.

[0053] For example, to achieve this height adjustment function, the nose bridge support 5 can adopt a sliding connection mode, that is, one or more sliding grooves are provided on one side of the support, and corresponding buckles or locking mechanisms are provided on the other side. These buckles or locking mechanisms can be selectively locked in multiple adjustment holes 10 to achieve adjustment of different heights. In addition, the design of the adjustment holes 10 can be circular, oval or other suitable shapes to ensure that the locking mechanism can be firmly fixed at the desired position.

[0054] In one embodiment, as Figure 4 shown, one of the features of the composite fixing device for enhancing CPAP nasal congestion fixation and comfort is that the male and female buckles 6 include an anti-slip layer 11. The main function of the anti-slip layer 11 is to prevent the buckle from loosening during user activities, thereby ensuring the fixing effect during long-term wearing. Specifically, the anti-slip layer 11 is usually made of materials with good friction properties, such as rubber or silicone, which can provide sufficient grip and reduce the displacement of the buckle during use. The anti-slip layer 11 can be firmly attached to the surface of the male and female buckles 6 through methods such as gluing, hot pressing or mechanical fixing, to ensure that it can play an anti-slip role in various environments.

[0055] In one embodiment, the specific design of the anti-slip layer 11 can include one or more protrusions or groove structures, which not only increase the friction coefficient of the surface, but also better fit the user's skin or clothing, further improving the stability of the fixing. For example, the anti-slip layer 11 can be designed as a mesh structure, which increases the contact area and friction force through dense small protrusions, thereby effectively preventing the buckle from sliding. This design can significantly improve the wearing experience of users during activities without affecting the aesthetics. Specifically, the anti-slip layer 11 can also be customized according to the user's skin quality or use environment to adapt to the individual needs of different users.

[0056] In one embodiment, the flexible nose pad 1 of the composite fixing device of the present application for enhancing the nasal congestion fixation and comfort of CPAP is provided with air holes 12 on both sides. The design of these air holes can not only ensure the air tightness of the device, but also provide good ventilation effect when the user wears it for a long time, thereby improving comfort. The flexible nose pad 1 is located between the user's nose bridge and both sides of the cheeks, and its material is usually soft silicone or other medical-grade soft material with strong flexibility, which can effectively fit different facial contours and ensure good fixation and sealing of the device in different movements and sleeping postures.

[0057] In one embodiment, the air holes are distributed on both sides of the flexible nose pad 1, forming symmetric or asymmetric arrangement. The diameter and spacing of each air hole are precisely designed to ensure air flow and prevent air leakage. Specifically, these air holes can be circular, oval or other polygons, which are manufactured in the material of the flexible nose pad 1 by laser drilling or mechanical stamping, etc., to ensure ventilation effect without damaging air tightness. In addition, the distribution density of air holes can be adjusted according to actual needs, for example, increasing the number of air holes in the parts where the user moves more, and reducing the number of air holes in the parts where stronger sealing is needed, to achieve the best user experience.

[0058] In one embodiment, the adjustable headband 2 of the composite fixing device of the present application for enhancing the nasal congestion fixation and comfort of CPAP is provided with a plurality of positioning holes 13 (see Figure 1 ). These positioning holes 13 are distributed on both ends and the middle part of the headband to provide the possibility of multi-point adjustment. By adjusting the position of the positioning holes 13, the user can select the appropriate positioning holes 13 for fine adjustment according to their head size and comfort needs. The design of positioning holes 13 on the headband not only enhances the fixation of the device, but also ensures the comfort of the user during use.

[0059] In one embodiment, the diameter and shape of the positioning holes 13 can be optimized according to actual needs to ensure that the positioning buckle can be firmly clamped into the positioning holes 13. For example, the positioning holes 13 can be designed as circular, oval or other polygons to match the adjustment buckle or other fixing parts on the headband. Specifically, the user aligns the adjustment buckle with the positioning hole 13 and presses it to embed it in the hole, thereby adjusting the length of the headband. This multi-point adjustment design allows the headband to be fixed at multiple positions, effectively adapting to the head sizes of different users.

[0060] In one embodiment, as shown in Figure 3As shown, the edges of the face pad 3 of the composite fixing device for enhancing the nasal congestion fixation and comfort of CPAP in the present application are rounded, which can reduce the pressure and friction of the pad 8 on the user's facial skin during wearing. In addition, the edges of the face pad 3 are also provided with soft silicone pads 14, which further improve the comfort of the pad 8 and reduce the discomfort of the skin. Such silicone pads 14 not only have good elasticity, but also can better adapt to the facial contours of different users, ensuring that the pad 8 is tightly attached to the face without causing compression.

[0061] Specifically, the rounding of the edges of the face pad 3 is achieved through precise machining processes, which can be completed by numerical control machine tools or precision grinding tools. The soft silicone pads 14 are manufactured by injection molding to ensure uniform thickness and smooth surface. During assembly, the soft silicone pads 14 are fixed on the edges of the face pad 3 by adhesive, ensuring firmness without loosening. This design ensures the integrity and stability of the pad 8, and also guarantees the comfortable experience of the user during long-term wearing.

[0062] In one embodiment, the connecting part of the side wing support 4 of the composite fixing device for enhancing the nasal congestion fixation and comfort of CPAP in the present application adopts a rotatable joint 15. Specifically, the connecting part of the side wing support 4 is designed as an adjustable angle structure, so that the user can adjust the position of the side wing support 4 according to different face shapes and use postures, thereby improving the comfort and stability of fixation. Through this adjustable design, the side wing support 4 can better fit the facial contours of the user, reducing the discomfort during wearing and improving the overall applicability of the device.

[0063] In one embodiment, the connecting part of the side wing support 4 includes two main parts: one is the base fixed on the main device, and the other is the rotatable joint 15 connected to the base. The base is fixed on the main body of the device, usually on both sides, while the rotatable joint 15 is connected between the base and the side wing support 4. Specifically, the rotatable joint 15 is provided with a rotating shaft and a stop mechanism inside, ensuring that the side wing support 4 can rotate freely within a certain range. For example, the user can manually adjust the angle of the side wing support 4 until it reaches the most suitable use state.

[0064] In one embodiment, the bottom of the bridge support 5 of the composite fixing device of the present application, which enhances the stability and comfort of CPAP nasal congestion, is equipped with a non-slip pad 16. This non-slip pad 16 can increase the friction between the bridge of the nose and the device, effectively preventing the device from slipping during wear, and improving the user's experience. The bridge support 5 is a part located at the front end of the entire device, directly contacting the user's nose bridge. It is usually made of flexible material to provide flexibility and comfort, while ensuring a good fit with the face. The non-slip pad 16 is located at the bottom of the bridge support 5, covering the surface that contacts the user's nose bridge.

[0065] The material selection of the non-slip pad 16 is also very important, and usually uses silicone or other high-friction coefficient elastic materials. These materials not only provide good friction, but also ensure comfort after long-term wear, reducing pressure marks and irritation to the skin. The non-slip pad 16 and the bridge support 5 can be fixed by gluing, hot melting or mechanical buckling, etc., to ensure the stability and durability of the device during use.

[0066] For example, in a specific embodiment, the non-slip pad 16 can be connected by setting a ring-shaped slot on its edge, and a flange matching the edge of the bottom of the bridge support 5 to realize buckling connection. This connection method is simple and firm, easy to produce and assemble. When installing, you just need to align the slot of the non-slip pad 16 with the flange at the bottom of the bridge support 5, and press gently to complete the fixation. The non-slip pad 16 designed in this way not only effectively prevents the device from slipping, but also facilitates cleaning and replacement later.

[0067] In actual operation, when the device is in use, the flexible nose pad 1 first contacts the user's nasal cavity, and its flexibility and fit shape can provide preliminary support and sealing effect, ensuring smooth airflow into the respiratory tract. At the same time, the bridge support 5 of the flexible nose pad 1 closely fits the contour of the user's nose bridge, increasing the stability and sealing of the nasal congestion, further reducing air leakage. Then, the user fixes one end of the adjustable headband 2 on the flexible nose pad 1, then wraps it around the back of the head, and adjusts it to the appropriate tightness through the adjustable buckle, which not only ensures the stability of the entire device, but also adapts to the head size of different users, making the wearing more comfortable.

[0068] Then, the face pad 3 is fixed at the middle position of the adjustable headband 2, fitting the user's face curve. The design of this pad 8 increases the contact area, further disperses the pressure, and reduces the discomfort caused by long-term wear. At the same time, the face pad 3 also plays a certain auxiliary fixing role, making the device more stable as a whole.

[0069] The side wing supports 4 are installed on both sides of the flexible nose pad 1, extending backward and connected with the adjustable headband 2 through flexible material. This design allows the side wing supports 4 to disperse pressure in multiple directions, further improving the stability and comfort of the device. In addition, the side wing supports 4 also provide additional fixing points, ensuring that the entire device is not easily displaced during use.

[0070] Finally, the male and female buckles 6 are used to firmly fix the adjustable headband 2 with the facial dressing pad 3, ensuring a tight connection between the components and enhancing the stability and consistency of the overall device. Through the cooperation of the above components, this device not only effectively enhances the fixation and sealing of CPAP nasal congestion, but also significantly improves the wearing comfort of users while ensuring efficient treatment.

[0071] The above specific embodiments further illustrate the purpose, technical solutions and beneficial effects of the embodiments of the present disclosure. It should be understood that the above description is only a specific embodiment of the present disclosure and is not intended to limit the protection scope of the present disclosure.
