Furthermore, this utility model also relates to a sleep apnea treatment device including the aforementioned modular multi-form breathing mask assembly. Background Technology

[0002] In current respiratory mask designs, different mask models typically require the development of dedicated molds for their corresponding support frames and mask bodies due to variations in shape and size. For example, three sets of molds are needed for S, M, and L-sized masks, resulting in high mold costs and low reusability. Furthermore, the traditional one-to-one correspondence between the support frame and mask body necessitates the replacement of specific components during after-sales maintenance, increasing repair costs and complexity.

[0003] On the other hand, due to the significant differences in the operating methods of different types of masks, users need to readjust to the wearing process of the support when changing masks, resulting in a high learning cost. Although there are modular medical device designs in the existing technology, they have not effectively solved the problem of rapid form switching of respiratory masks, resulting in the following technical problems still existing:

[0004] 1. The mask body and bracket have low assembly versatility, requiring specific matching parts for maintenance, resulting in high maintenance costs;

[0005] 2. The same face mask requires multiple sets of mask molds due to different silicone pad models, which increases the mold development cost;

[0006] 3. Users need to adapt to different support structures when choosing different masks, resulting in a poor user experience;

[0007] 4. Traditional bends and supports are fixedly connected, making them impossible to disassemble for cleaning, which affects hygiene and ease of maintenance. Utility Model Content

[0037] like Figure 1As shown, the modular multi-form breathing mask assembly of this embodiment includes a hose 100, a bend 200, a support 300, and a mask body 400 arranged separately; the support 300 is positioned and connected to the mask body 400, the bend 200 is fastened and fixed to the mask body 400, and the hose 100 is fastened and fixed to the bend 200; by inserting and removing the fastening and fixing, at least one of the hose 100, the bend 200, the support 300, or the mask body 400 can be quickly replaced. This utility model relates to a modular, multi-form respiratory mask assembly. Through a split-module design, the tubing 100, bend 200, support 300, and mask body 400 can be independently disassembled and assembled, and quick replacement is achieved through a snap-fit ​​fastening method. Standardized snap-fit ​​interfaces between components break the traditional one-to-one correspondence, allowing for interchangeable combinations of different models, reducing reliance on specific parts during maintenance and minimizing spare parts inventory requirements. The split design allows the mask body 400 and support 300 to be compatible with various silicone pad 500 models, avoiding repeated mold openings due to differences in silicone pad 500 dimensions and improving mold reuse rate. The unified snap-fit ​​method simplifies the assembly process for different masks, eliminating the need for users to readjust to wearing different models of support 300, reducing learning costs. The detachable structure solves the cleaning difficulties caused by the traditional fixed connection of the bend and support, facilitating independent cleaning and disinfection of each component. The plug-in snap-fit ​​allows for flexible component replacement to meet different treatment needs or size adjustments, avoiding resource waste associated with replacing the entire assembly. The modular design and plug-in fastening structure improve component interchangeability, reduce production costs, and simplify use and maintenance. The unified assembly method reduces user learning costs, the detachable structure facilitates cleaning and disinfection, and the quick replacement of components meets different treatment needs and size adaptations.

[0038] like Figure 1 and Figure 2As shown, in this embodiment, the bracket 300 is provided with a positioning hole 301, and the bracket 300 is also provided with a U-shaped limiting rib 302 and / or a strip-shaped limiting rib 303; the bracket 300 is sleeved on the cover 400 through the positioning hole 301, and is positioned and connected to the cover 400 through the U-shaped limiting rib 302 and / or the strip-shaped limiting rib 303. Optionally, the bracket 300 is fixed between the bend 200 and the cover 400 by the fastening force between the bend 200 and the cover 400. The mating structure between the positioning hole 301 and the cover 400 ensures the accuracy of the assembly position of the bracket 300 and the cover 400, avoiding misalignment during installation; the U-shaped limiting rib 302 and the strip limiting rib 303 provide multi-directional limiting function, enhancing the stability of the connection between the bracket 300 and the cover 400; the guiding function of the U-shaped limiting rib 302 and / or the strip limiting rib 303 simplifies the assembly operation process, enabling rapid positioning and disassembly; the design of the U-shaped limiting rib 302 and / or the strip limiting rib 303 can be adapted to the interfaces of cover 400 with different shapes, improving the versatility of components. Optionally, U-shaped limiting ribs 302 and / or strip-shaped limiting ribs 303 are respectively arranged on opposite sides of the positioning hole 301; the U-shaped limiting ribs 302 and / or strip-shaped limiting ribs 303 distributed on opposite sides form a balanced positioning and limiting force, avoiding connection misalignment or loosening caused by unilateral force, and improving assembly stability; the U-shaped limiting ribs 302 and / or strip-shaped limiting ribs 303 arranged oppositely simultaneously clamp and limit the cover 400 from both sides, preventing displacement or rotation of the bracket 300 and the cover 400 in the horizontal direction; the U-shaped limiting ribs 302 and / or strip-shaped limiting ribs 303 arranged oppositely provide multi-directional guiding function, reducing assembly angle deviation, and can still guide correct fastening even if there is slight misalignment.

[0039] like Figure 1 and Figure 2 As shown, in this embodiment, the bracket 300 adopts a forehead pad type bracket or a wing type bracket.

[0040] like Figure 1 and Figure 3As shown, in this embodiment, the end of the bent pipe 200 facing the cover 400 is provided with a fixing boss 201 and a positioning disc 202. The positioning disc 202 is used to limit and fix the bracket 300 when the bent pipe 200 is assembled with the cover 400. The fixing boss 201 is arranged along the circumference of the bent pipe 200 and is located at the edge of the pipe end of the bent pipe 200. The bent pipe 200 is fastened and fixed to the cover 400 through the fixing boss 201 and the positioning disc 202. The positioning disc 202 forms an axial stop structure to ensure the precise insertion depth of the bend 200 and the cover 400 during assembly, and to ensure accurate assembly without over-insertion or under-insertion. The circumferentially arranged fixing bosses 201 provide multi-point distributed interlocking, enhancing the torsional resistance of the connection between the bend 200 and the cover 400. The positioning disc 202 also limits and fixes the bracket 300, forming an integrated assembly structure and simplifying the fit between components. The design of the fixing bosses 201 at the edge of the pipe end maximizes the use of the contact area, disperses local stress, and improves the durability of the connection.

[0041] like Figure 1 and Figure 3 As shown, in this embodiment, the end of the bent pipe 200 facing the cover 400 is configured as a first pipe segment 203 and a second pipe segment 204. The first pipe segment 203 is arranged away from the positioning disc 202, and the second pipe segment 204 is arranged close to the positioning disc 202. The fixing boss 201 is located at the pipe end edge of the first pipe segment 203, and the radial dimension of the second pipe segment 204 is greater than the radial dimension of the first pipe segment 203. A stepped structure is formed between the first pipe segment 203 and the second pipe segment 204, and a concave structure is formed between the second pipe segment 204 and the fixing boss 201. The bent pipe 200 is fastened and fixed to the cover 400 through the fixing boss 201, the positioning disc 202 and the concave structure. By designating the end portion of the bend 200 as the first pipe segment 203 and the second pipe segment 204, and in conjunction with the stepped structure and concave structure, the stepped structure formed by the first pipe segment 203 and the second pipe segment 204 provides axial graded limiting, ensuring precise alignment of the bend 200 and the cover 400 during assembly, and preventing excessive assembly depth or skewness; the increased radial dimension of the second pipe segment 204, combined with the concave structure, forms an interference fit area with the cover 400, enhancing the airtightness and pull-out resistance of the connection; the combined effect of the stepped structure and the concave structure causes the interlocking stress to be distributed along the pipe segment gradient, avoiding local stress concentration and improving the fatigue life of the connection; the small diameter design of the first pipe segment 203 forms a guide part, facilitating initial insertion; the large diameter structure of the second pipe segment 204 provides final positioning, realizing staged assembly.

[0042] like Figure 3As shown, in this embodiment, the end of the bend 200 facing the hose 100 is provided with a fixing boss 201 and a positioning disc 202. The positioning disc 202 is used to limit and fix the hose 100 when the bend 200 and the hose 100 are assembled. The fixing boss 201 is arranged along the circumference of the bend 200 and is located at the edge of the pipe end of the bend 200. The bend 200 is fastened and fixed to the hose 100 through the fixing boss 201 and the positioning disc 202. The positioning disc 202 forms an axial stop structure to ensure the precise insertion depth of the bend 200 and the hose 100 during assembly, and to ensure accurate assembly without over-insertion or under-insertion. The circumferentially arranged fixing bosses 201 provide multi-point distributed interlocking action, enhancing the anti-torsion performance of the connection between the bend 200 and the hose 100. The positioning disc 202 also limits and fixes the hose 100, forming an integrated assembly structure and simplifying the fit between components. The design of the fixing bosses 201 located at the edge of the pipe end maximizes the use of the contact area, disperses local stress, and improves the durability of the connection.

[0043] like Figure 3 As shown, in this embodiment, the end of the bend 200 facing the hose 100 is configured as a first pipe segment 203 and a second pipe segment 204. The first pipe segment 203 is arranged away from the positioning disc 202, and the second pipe segment 204 is arranged close to the positioning disc 202. The fixing boss 201 is located at the pipe end edge of the first pipe segment 203, and the radial dimension of the second pipe segment 204 is greater than the radial dimension of the first pipe segment 203. A stepped structure is formed between the first pipe segment 203 and the second pipe segment 204, and a concave structure is formed between the second pipe segment 204 and the fixing boss 201. The bend 200 is fastened and fixed to the cover 400 through the fixing boss 201, the positioning disc 202 and the concave structure. By designating the end portion of the bend 200 as the first pipe segment 203 and the second pipe segment 204, and in conjunction with the stepped structure and concave structure, the stepped structure formed by the first pipe segment 203 and the second pipe segment 204 provides axial graded limiting, ensuring precise alignment of the bend 200 and the hose 100 during assembly, preventing excessive depth or misalignment during assembly; the increased radial dimension of the second pipe segment 204, combined with the concave structure, forms an interference fit area with the hose 100, enhancing the airtightness and pull-out resistance of the connection; the combined effect of the stepped structure and the concave structure causes the interlocking stress to be distributed along the pipe segment gradient, avoiding local stress concentration and improving the fatigue life of the connection; the small diameter design of the first pipe segment 203 forms a guide section for easy initial insertion; the large diameter structure of the second pipe segment 204 provides final positioning, realizing staged assembly. Optionally, the outer wall surface of the second pipe segment 204 is provided with annular reinforcing ribs; or multiple annular reinforcing ribs are arranged at intervals along the axial direction of the second pipe segment 204.

[0044] like Figure 1 and Figure 4As shown, in this embodiment, the cover 400 is provided with a vent 401; the outer wall of the vent 401 extends outward to form an outer protruding edge 402, and the inner wall of the vent 401 extends inward to form an inner protruding edge 403. The cover 400 is positioned and connected to the bracket 300 through the outer protruding edge 402, and the cover 400 is fastened and fixed to the bent pipe 200 through the inner protruding edge 403; and / or a first positioning component 404 is provided between the cover 400 and the outer wall of the vent 401, and the cover 400 is positioned and engaged with the bracket 300 through the first positioning component 404; and / or a second positioning component 405 is provided on the outer surface of the cover 400 near the vent 401, and the cover 400 is positioned and engaged with the bracket 300 through the second positioning component 405. By providing an outer protruding edge 402, an inner protruding edge 403, and a positioning component structure at the ventilation hole 401 of the hood 400, the outer protruding edge 402 is fixedly engaged with the bracket 300, and the inner protruding edge 403 is fastened to the bend 200 to achieve a tight connection between the hood 400, the bend 200, and the bracket 300, thus ensuring an airtight connection between the hood 400 and the bend 200 and guaranteeing the airtightness of the breathing airflow passage; the first positioning component 404 achieves precise radial positioning through the engagement of the outer wall of the ventilation hole 401 with the bracket 300, and the second positioning component... Component 405 achieves axial auxiliary positioning through the cooperation between the outer surface of the cover 400 and the bracket 300, forming multi-level positioning constraints to prevent relative displacement between components; the coordinated design of the outer convex edge 402 and the inner convex edge 403 allows the bracket 300 and the bend 200 to be disassembled and assembled independently, avoiding interference problems between components in traditional integrated structures and improving maintenance convenience; the extended structure of the outer convex edge 402 and the inner convex edge 403 enhances the local stiffness of the edge of the vent 401, disperses the fastening stress, and avoids the risk of deformation caused by breathing air pressure.

[0045] like Figure 1 and Figure 4 As shown, in this embodiment, the first positioning component 404 between the cover 400 and the outer wall of the vent 401 adopts a positioning protrusion. The positioning protrusion and the corresponding structure of the bracket 300 form a mechanical interference fit to ensure the radial alignment accuracy of the cover 400 and the bracket 300 during assembly and avoid assembly misalignment; the asymmetrical or specific arrangement of the positioning protrusion can form a foolproof structure, forcing the realization of a unique correct assembly orientation and preventing the reverse or misaligned installation of components; the mating surface of the positioning protrusion and the bracket 300 forms an additional friction contact area, providing auxiliary constraints on the basis of fastening and fixing, and suppressing the micro-displacement between components; compared with independent positioning parts, the integrally formed positioning protrusion avoids the assembly of additional parts, reduces production costs and improves structural reliability.

[0046] like Figure 1 and Figure 4As shown, in this embodiment, the second positioning component 405 on the outer surface of the mask 400 near the ventilation hole 401 adopts a positioning groove. The positioning groove and the corresponding protrusion structure of the bracket 300 form an axial fit, precisely controlling the assembly depth of the mask 400 and the bracket 300 to prevent overpressure or loosening; the gradually expanding inlet structure of the positioning groove guides the protrusion of the bracket 300 to slide in, reducing assembly resistance and realizing rapid blind operation positioning; the sidewall of the positioning groove and the bracket 300 form a surface contact constraint, effectively resisting the rotational torque generated during the use of the breathing mask and maintaining the relative position stability between components; compared with a simple outward protruding positioning structure, the positioning groove design avoids increasing the outer contour size of the mask 400 and maintains the overall structural compactness.

[0047] like Figure 1 and Figure 5 As shown, in this embodiment, a silicone pad 500 is provided on the cover 400. The silicone pad 500 is at least one of an L-shaped silicone pad, an M-shaped silicone pad, or an S-shaped silicone pad.

[0048] The sleep apnea treatment device of this embodiment includes the above-mentioned modular multi-form breathing mask assembly.

[0049] In implementation, a modular multi-form respiratory mask system is provided, using a universal mask body 400, allowing the same mask body 400 to correspond to silicone pads 500 of different sizes, reducing mold costs; the same mask body 400 is used to correspond to different types of supports 300, such as forehead pad supports and wing-shaped supports, to meet the wearing needs of different patients for different supports 300; to avoid separate assembly and fixation of the support 300 and the mask, a bent tube 200 is used to directly connect and fix the mask, and the support 300 is sandwiched between the bent tube 200 and the mask body 400 for connecting the headband, reducing the assembly relationship between the support 300 and the mask, which is conducive to realizing multiple wearing methods of the support 300.

[0050] The beneficial effects are:

[0051] 1. It has a modular design concept, making the mask body 400 a universal assembly module. The same mask body 400 can be matched with different types of brackets 300 and silicone pads 500 of different sizes, which improves the degree of commonality of parts and reduces maintenance costs.

[0052] 2. The number of molds for the 400mm cover has been reduced by 66% (from 3 sets to 1 set), resulting in lower mold and material costs;

[0053] 3. It can also meet the wearing needs of users with different brackets 300, thus reducing the learning cost for users.

[0054] 4. Compared with the traditional fixed structure, the bend 200, bracket 300, and mask can all be disassembled independently, which facilitates later cleaning and maintenance.

[0055] More specifically, a universal face mask body 400 is provided, which can be adapted to silicone pads 500 of different sizes (S\M\L);

[0056] The mask body 400 can be adapted to different shaped brackets 300. Currently, common brackets 300 on the market include forehead pad type and wing type, both of which can achieve universal mask assembly. Figure 6 As shown;

[0057] The mask structure includes a bent tube 200, a flexible tube 100, a bracket 300, a head strap buckle, a mask body 400, a silicone pad 500, a head strap, a connector, and a bracket bag;

[0058] The cover 400 is provided with a vent 401. The inner wall of the vent 401 extends outward to form an outer convex edge 402 and an inner convex edge 403. A first positioning component 404 is provided on the outer wall of the outer convex edge 402. A second positioning component 405 is provided on the cover 400 at the same time. The first positioning component 404 is a protrusion and the second positioning component 405 is a groove.

[0059] The bracket 300 has a circular limiting hole (positioning hole 301) that fits onto the outer protruding edge 402 of the cover 400. The side wall of the circular limiting hole (positioning hole 301) has a notch that mates with the first positioning component 404. The bracket 300 has a buckle (U-shaped limiting rib 302) on its inner surface facing the cover 400 that mates with the second positioning component 405 for positioning. The buckle may be rib-shaped.

[0060] The bent pipe 200 is inserted into the vent hole 401, and the end connected to the cover 400 has two fixing bosses 201 for engaging and fixing with the inner protruding edge 403 of the cover 400; the bracket 300 is snapped between the bent pipe 200 and the cover 400.

[0061] The bend 200 has a convex positioning disc 202 at the connection end with the cover 400, which is used to limit the assembly with the cover 400, and at the same time limit and fix the bracket 300 to prevent the bracket 300 from coming out and loosening.

[0062] Between the positioning disc 202 and the fixing boss 201 of the bent pipe 200, there is a first surface (first pipe segment 203) and a second surface (second pipe segment 204). The first surface and the second surface are horizontally misaligned to form a stepped structure, and the second surface is concave relative to the first surface and the boss.

[0063] The inner convex edge of the cover 400 protrudes along the inner sidewall of ...

[0064] The support bag is mounted on the support 300 to fit the face and increase wearing comfort.

[0065] The bracket 300 is clamped between the bent tube 200 and the cover 400 during assembly and is used to connect the headband. Specific implementation examples:

[0067] During assembly, first, the bracket 300 is mounted onto the mask body 400 using the limiting components (U-shaped limiting ribs 302 and / or strip-shaped limiting ribs 303) and positioning holes 301. Then, the bent tube 200 is installed into the mask body 400 by aligning the first positioning component 404 and the second positioning component 405, so that the inner convex edge 403 of the mask body 400 is fastened and fixed with the fixing boss 201 on the bent tube 200. When the bracket 300 needs to be replaced, first, the bent tube 200 is manually pulled out of the mask body 400. After pulling out the bent tube 200, the old bracket 300 is removed, and the new bracket 300 is installed according to the first positioning component 404 and the second positioning component 405 of the mask body 400. After installation, the fixing boss 201 on the bent tube 200 is re-fastened and fixed with the inner convex edge 403 of the mask body 400, realizing the quick replacement of different brackets 300.
