Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a frame component without elbows, which is suitable for one or more of the diagnosis, treatment and improvement of respiratory diseases. 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 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] Although there are many patients with sleep apnea, most patients fail to receive long-term treatment due to the interference of comfort, ease of use, stability, adaptability, sealing and noise of treatment equipment. Since the face has a complex three-dimensional shape and the bone contours of each person are more or less different, there are great difficulties in the sealing design of the mask. One of the important challenges is that the mask must be able to effectively seal the patient's respiratory tract and cooperate with the frame. At present, most mask systems use a combination of nasal pillows, frames, elbows, and straps to try to fix the nasal pillows to the patient's face through the combination of rigid frames and straps. The weight of the frame itself plus the weight of the matching elbow may cause some mask systems to be heavier overall, causing red marks and pressure sores on the face, reducing comfort of use, and the more parts there are, the more complicated the usage steps are. In order to alleviate the discomfort caused by the mask, some smaller patient interfaces are also sold on the market, such as nasal cannulas. These patient interfaces may be lighter and more comfortable than masks, but they may lack stability because they are too light. During sleep, the head, facial bones and muscles will move to a certain extent, so unfixed tubes may fall or leak, resulting in poor treatment results.

[0004] Therefore, a new type of frame assembly without elbows is needed to overcome the limitations of existing devices and provide a more stable, simpler and easier to operate solution. While maintaining the main functions of the product, a better user experience is achieved, the overall comfort of the product is improved, it is easier to clean, and the overall service life of the product is greatly extended.

[0072] To implement the frame assembly without elbows provided by the present invention, the nose pillow is first connected to the side of the frame away from the fixing port, and the first end of the gas supply hose connected to the fixing port of the frame is held by one hand, so that the side of the frame facing the face is aligned with the user's nose, so that the nose pillow seals the user's nose to provide pressurized or breathable gas to the user's nose. After sealing with the nose pillow, the two side connectors of the first connecting part of the frame are fixed to the user's head with the other hand, thereby realizing the connection between the frame and the user, and fixing the nose pillow to the user's nose, thereby improving the stability of the nose pillow when in use. The fixing port of the frame is connected to the gas supply hose, and the first end of the gas supply hose is connected to the frame through the fixing port. The middle of the gas supply hose is an intermediate hose with multiple uniformly foldable walls, so the intermediate hose has ductility and can rotate relative to the frame. To achieve flexible use by the user, the second end of the gas delivery hose is used to connect with other tubular connector interfaces to provide breathable gas into the gas delivery hose, thereby meeting the normal breathing of the user. The frame assembly is also provided with an exhaust channel, and the exhaust channel can be provided on the frame, the first end, or an exhaust joint between the first end and the fixed port. The exhaust channel can be provided in the form of an exhaust net, or in the form of an exhaust hole matched with a noise reduction component. Through the provision of the exhaust channel, the gas exhaled by the user can be discharged in time, so that the user can inhale fresh gas in time. The exhaust channel is provided on the frame or the first end, and the exhaust function of the frame assembly can be realized without adding new devices and equipment, reducing redundant components, and reducing the overall weight of the frame assembly. It is more convenient to use and can also enhance the user's experience when worn on the user's head.

[0073] The respiratory mask with foam pad implementing the present invention has at least the following beneficial effects:

[0074] 1) Reduce components and reduce weight: Most mask systems on the market use frames, elbows, catheters and straps to connect the patient interface pad with other tubular connectors to form a complete gas delivery channel to deliver pressurized gas to the patient's airway to prevent apnea. When the mask system is worn for a long time at night, the weight of the mask system may oppress the user, causing some users to feel uncomfortable and causing sleep obstructions such as indentation and psychological pressure. Therefore, our product creatively constructs the frame assembly into three parts - frame, gas hose and side connector, and combines the redesign of the nasal pillow to form a new nasal mask system. In the new frame assembly, the frame is designed to be directly connected to the gas hose, and the exhaust channel on the elbow is redesigned in combination with the frame assembly, removing the traditional elbow component and setting an exhaust channel on the frame, which can be combined with noise reduction materials. Such a design can not only reduce the noise of the product and ensure that the product provides a quiet use environment for users when in use, but also reduce the overall weight of the assembly, making it more comfortable to wear, and improving the user's comfort and user experience.

[0075] 2) Simplify the user's usage: The connection between the gas hose and the frame is a detachable connection, which simplifies the installation process and allows users to quickly disassemble and wear the mask system, avoiding the situation where the user needs to get up at night or move quickly in case of an emergency and cannot separate the mask from the machine in time. The second end of the gas hose can also rotate 360°; compared to the current permanent connection between the gas hose and the frame, the detachable and rotatable structure can reduce the probability of the gas hose being tangled due to the two ends being fixed, greatly improving the flexibility and adaptability of the frame assembly. In addition, the detachable pipe also provides users with more convenient cleaning and replacement options. Users can clean and maintain it regularly to keep the mask system in good condition and avoid potential health risks.

[0076] 3) More economical and environmentally friendly for users: The application of detachable hoses can bring us many economic and environmental advantages. Due to the special nature of the hose, its material is more easily damaged than other components of the assembly. For users, this detachable design allows that when the gas hose or other components are damaged during use, only the damaged part needs to be replaced separately, without having to replace the entire frame assembly. This reduces the cost of use and maintenance costs and extends the service life of the entire system, improves the service life and reusability of the gas hose, and makes the maintenance and repair of the entire frame assembly more efficient, more economical and environmentally friendly.

[0077] 4) Convenient manufacturing for producers: From a production perspective, the use of a detachable connection structure for production and assembly can avoid the problem of easy damage caused by traditional welding or fixed connection production of one-piece frame hoses, thereby reducing the defective rate; when it is necessary to inspect or replace damaged parts, only simple mechanical disassembly is required for rapid inspection operations, ensuring the continuous stability of the production process; through this simple mechanical structure, the operating efficiency of the production line is maintained, bringing a more efficient and reliable production process to the manufacturer.

[0078] 5) Improved comfort: To improve wearing comfort, we have given special consideration to the design of the side connector. In order to adapt to facial deformation, we selected a deformable material with support and adopted an integrated injection molding process to avoid facial discomfort caused by connection marks. The overall side connector presents a smooth arc shape, which better fits the deformation of the user's face and provides a more comfortable wearing experience. A variety of connection options are provided, including buckles, snaps, Velcro, knobs, magnetic suction, etc., to achieve flexible connection with the frame. In order to further improve the usability of the product, the L / R embossed logo, that is, the left and right logo, is marked on the book strap to help users wear the nasal mask more conveniently and quickly in dark environments, providing users with a more intelligent and convenient use experience.

[0079] In summary, our product creatively constructs the frame assembly into a combination of three parts (frame, gas hose and side connector), which maintains the main functions of the product while achieving a better user experience, improving the overall comfort of the product, making it easier to clean, and also greatly extending the overall service life of the product. In addition, the detachable design can effectively reduce production costs and make a positive contribution to environmental protection. The disassembly structure combination and manufacturing process make the production process more efficient and economical, reducing resource waste; at the same time, its detachable and reusable characteristics are also conducive to reducing waste generation and being more environmentally friendly. Overall, this product design of a frame assembly without elbows not only improves functionality and user experience, but also takes into account comfort and environmental protection, which will bring users a more convenient, efficient and sustainable user experience.

The frame 1 has a fixing port 11 for connecting to the gas hose 2. The fixing port 11 is arranged on the frame 1. The frame 1 is connected to the gas hose 2 through the fixing port 11, so that the gas in the gas hose 2 is transported to the nasal pillow 6 through the connection of the frame 1 and then input into the user's nose. The fixing port 11 is in the shape of a tube with a certain length, which provides a sufficient contact surface for the connection between the gas hose 2 and the frame 1, and is used to stabilize the connection between the frame 1 and the gas hose 2. Specifically, the wall thickness of the fixing port 11 is 0.3-5 mm, and the length is 0.3-30 mm. According to different situations, a frame 1 with different sizes of the fixing port 11 is selected to meet the various needs of users, thereby improving the applicability of the frame assembly.

[0109] The gas delivery hose 2 has a total length of 200-600 mm and is used to deliver breathable gas to the user. The gas delivery hose 2 is made of a material including, but not limited to, a plastic material, silicone, a thermoplastic elastomer, and silicone. The gas delivery hose 2 includes a first end 22 connected to the fixing port 11 of the frame 1, and a second end 23 connected to other tubular connectors (such as Figure 2), an intermediate hose 21 is connected between the first end 22 and the second end 23. The middle of the intermediate hose 21 is a hollow tube, and the outer surface has a plurality of uniform, continuous and foldable walls to achieve compression and stretching of the intermediate hose 21 relative to the first end 22 and the second end 23. The outer diameter range of the gas hose 2 is 25-45mm, the wall thickness range of the gas hose 2 is 1-5mm, and the telescopic range of the gas hose 2 is 80%-120%. Therefore, the second end 23 of the gas hose 2 can be stretched and compressed relative to the first end 22, so that the user can still move within a certain range after wearing the frame assembly, thereby improving the user's range of movement. In order to simplify the internal structure and reduce the overall weight, specifically, the first end portion 22 of the gas hose 2 is roughly cylindrical, so the cross-section of the fixing port 11 is also circular. In other embodiments, the cross-section of the gas hose 2 may also be elliptical or polygonal or other shapes. The fixing port 11 is in a shape corresponding to the gas hose 2 to facilitate the connection between the fixing port 11 and the gas hose 2; the fixing port 11 is 10-25 mm long, 15-25 mm in outer diameter, and 1-3 mm in wall thickness. In order to ensure that sufficient gripping area is provided for the patient during use and the overall weight is not increased due to excessive volume, the first end portion 22 is 10-25 mm long and weighs approximately 1-10 grams.

[0110] The first end portion 22 is detachably connected to the fixing opening 11 and can be connected by any of a buckle, a snap, a friction connection, a Velcro, a knob, and a magnetic attraction (such as Figures 15 - 17 Only four connection methods are shown: snap, snap, friction connection and magnetic connection) Figure 15 -A shows that the first end 22 is snap-connected with the frame 1, that is, the first end 22 is made of elastic plastic material, a protrusion is provided on the inner wall of the first end 22, and a clearance groove matching the protrusion is provided on the outer wall of the fixing port 11, so that the first end 22 is sleeved on the fixing port 11. In other embodiments, the fixing port 11 can also be sleeved on the outer side of the first end 22, that is, a clearance groove is provided on the first end 22, and a corresponding protrusion is provided on the fixing port 11, so as to realize the detachable connection between the gas delivery hose 2 and the frame 1. The specific connection method can be seen in Figure 17 ;like Figure 15 -B shows that the first end portion 22 is connected to the frame 1 by means of snaps. Specifically, the first end portion 22 is made of elastic plastic material, and an elastic member is provided on the inner wall of the fixing opening 11. The first end portion 22 is squeezed into the fixing opening 11 to achieve a tight connection between the elastic member in the fixing opening 11 and the outer wall of the first end portion 22. Similarly, in other embodiments, a connection method in which the first end portion 22 is tightly sleeved in the fixing opening 11 can also be adopted, that is, the fixing opening 11 is made of elastic plastic material, and an elastic member is provided on the inner wall of the first end portion 22. The first end portion 22 is squeezed into the fixing opening 11 to achieve a tight connection between the elastic member in the fixing opening 11 and the outer wall of the first end portion 22;Figure 15 -The first end 22 in C is an elastic part, which is directly squeezed into the fixing port 11 through deformation, and is connected to the outer wall of the frame 1 by using the friction force of the elastic part. The material of the first end 22 can be rubber, silicone, thermoplastic elastomer, etc., which are different from the material of the frame. For example, silicone material with a hardness of 30-70 Shore A and TPE with a hardness of 20-80 Shore A. The material is between soft and hard, has a good sealing effect and is wear-resistant, and can be deformed through material properties to connect to the fixing port 11. Figure 16 The figure shows the magnetic connection between the first end portion 22 and the fixing port 11, that is, magnets are arranged at the connecting ends of the first end portion 22 and the fixing port 11, and the connection between the first end portion 22 and the fixing port 11 is achieved through the mutual attraction of the magnets. The second end portion 23 includes a first portion 231 and a second portion 232. The first portion 231 is a cylindrical tube body fixedly connected to the second end portion 23. The second portion 232 is connected to an end of the first portion 231 away from the intermediate hose 21 and can be coaxially rotated relative to the first portion 231, thereby realizing the coaxial rotation of the second portion 232 relative to the intermediate hose 21. When the first end portion 22 of the gas hose 2 is connected to the fixed port 11, the first end portion 22 of the gas hose 2 and the frame 1 are in a mutually rotatable connection state, thereby realizing a 360-degree rotation of the gas hose 2 relative to the frame 1. The first end portion 22 and the intermediate hose 21 are in a fixed connection state, and the second portion 232 of the second end portion 23 rotates coaxially relative to the intermediate hose 21. Therefore, the second end portion 23 rotates coaxially relative to the first end portion 22 and the frame 1 to avoid knotting of the gas hose 2 during use. The second part 232 is used to connect with other tubular connectors with the same cross-sectional interface to realize the input of gas from the second end 23 into the gas delivery hose 2. Specifically, the second end 23 is generally cylindrical corresponding to the first end 22, with a length of approximately 45-55 mm, an outer diameter of approximately 15-25 mm, and a wall thickness of approximately 1-3 mm; the material can be made of elastic materials such as plastic and silicone to better realize the connection between the second end 23 and the external tubular connector.

[0111] The two ends of the frame 1 are provided with a first connection portion connected to the side connector 3. The side connector 3 has a front end 31 connected to the frame 1 and a corresponding rear end 32. The front end 31 is detachably connected to the frame 1. Specifically, it can be connected by a buckle (such as Figure 19 ), snaps, Velcro, knobs and magnets (such as Figure 18), in this embodiment, only two connection methods, snap-on and magnetic, are shown, i.e., magnets or connecting buckles are arranged at both ends of the side connector 3 and the frame 1 to realize a detachable connection between the two; the side connector includes a side connector and a side buckle, and the side connector 3 in the frame assembly is provided with two, for the convenience of production, the two side connectors 3 are symmetrical to each other and have the same size, and are respectively fitted to the left and right sides of the user's face, and in order to better fit the side connector 3 to the face, the side connector 3 is a continuous and smooth arc with a width of approximately 5-25 mm, and the straight-line distance range from the pad on the front end 31 of the side connector 3 to the point at the rear end 32 is 20-200 mm (such as Figure 20 ), the side connector 3 partially fits the face, combined with the straight-line distance from the tip of the nose to the tip of the ear of the user's face and the distance between the frame 1 and the user's face, the straight-line distance range from the pad on the front end 31 of the side connector 3 to the point at the rear end 32 is preferably 40-120 mm, and the wall thickness is about 1-2 mm. In order to improve production efficiency, the side connector 3 is integrated injection molding. Through structural characteristics such as wall thickness, length and shape, the side connector 3 wall frame 1 is more likely to deform, and can better conform to the user's face and thus deform, thereby improving the user's experience. The frame assembly is also provided with an exhaust channel 4. In this embodiment, the exhaust channel 4 is provided on the frame 1 and is located on both sides of the fixed port 11. The exhaust channels 4 on both sides of the fixed port 11 can be symmetrical or asymmetrical. The shape of the exhaust channel 4 can be any one of circular, semicircular, elliptical, rectangular, square, and other symmetrical or asymmetrical shapes. The ventilation area accounts for 20%-50% of the surface area of ​​the frame 1. At room temperature and air humidity of 75%-85%, positive pressure gas flows through the gas hose 2 When the first end 22 is reached, the wind speed is 2.25-2.45m / s. When the ventilation area accounts for 20% of the surface area of ​​the first end 22 of the gas hose 2, the wind speed tested in the exhaust channel 4 of the gas hose 2 is 1.2-1.3m / s, which meets the normal ventilation requirements and can prevent the occurrence of too little gas flowing in. When the ventilation area accounts for 50% of the surface area of ​​the first end 22 of the gas hose 2, the wind speed tested in the exhaust channel 4 of the gas hose 2 is 1.6-1.7m / s, which meets the positive pressure ventilation requirements. The exhaust channel 4 can be any one of an exhaust net, an exhaust hole, or a combination of an exhaust hole and a noise reduction component 7. When the exhaust channel 4 is an exhaust net (such as Figure 3 ), the exhaust net can be made of materials such as polyvinyl chloride, polypropylene, polytetrafluoroethylene or nylon; the exhaust net and the frame 1 can be directly connected and permanently fixed by adhesives, ultrasonic lamination, hot pressing, etc. to improve the tightness of the connection between the exhaust net and the frame 1; when the exhaust channel 4 is an exhaust hole (such as Figure 4), that is, a plurality of uniform circular holes are opened on the frame 1, the distribution and size of the circular holes are not unique, and in other embodiments, square holes or triangular holes can also be used. The setting of the exhaust holes can improve the convenience of setting the exhaust channel 4, reduce the weight of the frame assembly, and easily realize the exhaust gas discharge, which is beneficial to the timely gas exchange of the user; when the exhaust channel 4 is a combination of the exhaust hole and the noise reduction member 7 (such as Figure 5 ), it is only necessary to add a noise reduction component 7 at the position of the exhaust hole, and the noise reduction component 7 covers the outer surface of the exhaust hole, so as to reduce the sound of gas flow when the user exhales. According to the test method in ISO 17510, when the exhaust hole is used alone, the decibel of the sound is about 40-50 decibels. After adding the noise reduction component 7, the decibel of the sound is about 19-30 decibels, and the noise can be reduced by 10-30 decibels. The noise reduction effect of the frame assembly is better. The noise reduction component 7 can be noise reduction cotton or cloth; the material of the noise reduction cotton can be made of one of polyester, polypropylene, polyethylene, nylon, vinylon and natural fabric. The exhaust channel 4 is arranged on the frame 1, and the exhaust function of the frame assembly can be realized without adding new devices and equipment. The redundant parts are reduced, and the overall weight of the frame assembly can be reduced, which makes it more convenient to use. When worn on the user's head, the user's experience can also be improved. When the frame assembly is in use, the various components are kept connected to facilitate timely use, thereby improving the use efficiency of the frame assembly. The total weight of the frame assembly is approximately 20-25 grams, and the overall weight is reduced compared to the prior art, so the user experience is better.

[0112] When the frame assembly provided in this embodiment is used, the nose pillow 6 is connected to the inner side of the second connecting portion of the frame 1 (such as Figure 22 ), hold the first end 22 of the gas delivery hose 2 connected to the fixing port 11 of the frame 1 with one hand, align the side of the frame 1 facing the face with the user's nose, so that the nasal pillow 6 seals the user's nose to provide pressurized or breathable gas to the user's nose, and after sealing with the nasal pillow 6, use the other hand to fix the two side connectors 3 of the first connecting part of the frame 1 to the user's head, thereby achieving the connection between the frame 1 and the user, and fixing the nasal pillow 6 at the user's nose (such as Figure 23 ), thereby improving the stability of the nasal pillow 6 during use.

[0113] In summary, removing the traditional elbow structure, directly connecting the frame 1 with the gas hose 2, and combining the exhaust channel 4 with the frame 1 can not only reduce the noise of the product and ensure that the product provides a quiet environment for users when in use, but also reduce the overall weight of the component, making the user more comfortable to wear, thereby improving the user's comfort and user experience.

[0114] In another embodiment, the fixing opening 11 has at least one of the following characteristics: 1) The angle α formed by the central axis of the fixing opening 11 and the straight line connecting the point on the frame 1 farthest from the fixing opening 11 and the central point of the fixing opening 11 toward the face is in the range of 0°-90° (e.g. Figure 12 ) ; 2) the angle β formed by the axis of symmetry of the frame 1 and the central axis of the fixing port 11 is in the range of 30°-150° (such as Figure 13 ). Considering the comfort of the user using the product, the frame 1 is designed to have a tendency to bend toward the face. At the same time, no matter where the fixing port 11 points, the maximum length extending toward the face does not exceed the point A at the farthest end of the frame 1 or the point H flush with A due to the limitation of the length range of the fixing port 11 by ergonomics. At this time, the center point O of the fixing port 11 cannot coincide with H, and OH obtains the shortest value. In the right triangle HOA, the angle corresponding to OH gradually increases as the point O moves outward, and the complementary angle α gradually decreases. Therefore, the range of angle α is 0°-90° (such as Figure 13 Considering the durability of the product, the gas hose 2 is more susceptible to damage than other parts due to the special nature of the material. If the connection angle between the gas hose 2 and the frame 1 is properly designed, the incidence of damage to the gas hose 2 due to stress and other problems can be reduced, and different angles β can meet the different needs of patients for the placement of the gas hose 2 (such as Figure 14 ), and the gas hose 2 is kept with a suitable force distribution on the frame 1, and is not easy to be pierced. Therefore, the angle β obtained from the symmetry axis obtained from the positive viewing angle of the frame 1 and the central axis of the fixing port 11 is defined in the range of 30°-150°, such as Figure 14 A schematic diagram showing the use of different angles shows that the optimal range of β is approximately 30°-90°, wherein when β is approximately equal to 30°, the gas hose 2 just touches the patient's chin, and when β is approximately equal to 150°, another way of placing the gas hose 2 can be provided to the patient, that is, placing the gas hose 2 above the patient's face, thereby avoiding the patient from frequently changing sleeping positions at night and pulling the gas hose 2; a variety of angle options can replace some functions of the elbow, providing patients with a comfortable treatment experience.

[0115] In another embodiment, according to different users' different preferences for the connection method between the gas hose 2 and the frame 1, the fixing port 11 has multiple orientations (such as Figure 21 ), can be set to face the side of the gas hose 2 ( Figure 21 The left schematic diagram in the middle), that is, it is set to protrude outward, and it can also be set to face one side of the frame 1 ( Figure 21The first setting method exposes the fixing port 11, which can better realize the connection between the fixing port 11 and the first end 22 of the gas hose 2, and improve the installation efficiency of the frame 1 and the gas hose 2. The second setting method arranges the tubular part of the fixing port 11 in the cavity of the frame 1, which can reduce the leaking part of the fixing port 11, reduce the space occupied by the fixing port 11, and improve the space utilization rate of the frame assembly. The two methods are used according to different needs, which can meet more applicable scenarios and improve the application scope of the frame assembly.

[0116] In another embodiment, in order to further improve the convenience of using the product, L / R reliefs are respectively marked on the two side connectors 3, where L corresponds to the left side of the user and R corresponds to the right side of the user. That is, adding left and right markings can help the user to quickly wear the nasal pillow 6 even in a dark environment, thereby improving the convenience of using the frame assembly and providing the user with a more intelligent and convenient product usage experience.

[0117] Example 2

[0118] This embodiment provides a frame assembly without an elbow. The difference between the second embodiment and the first embodiment lies in the location of the exhaust passage 4.

[0119] The frame assembly is further provided with an exhaust passage 4. In the present embodiment, the exhaust passage 4 is provided on the first end portion 22 of the gas delivery hose 2 and is located on the tubular side wall of the first end portion 22. The shape of the exhaust passage 4 can be any one of a circular, semicircular, elliptical, rectangular, square, or other symmetrical or asymmetrical shapes. The ventilation area accounts for 20%-50% of the surface area of ​​the first end portion 22. The exhaust passage 4 can be any one of an exhaust net, an exhaust hole, or a combination of an exhaust hole and a noise reduction member 7. When the exhaust passage 4 is an exhaust net (such as Figure 6 ), the exhaust net is coated on the side wall of the first end portion 22, and the exhaust net can be made of materials such as polyvinyl chloride, polypropylene, polytetrafluoroethylene or nylon; the exhaust net and the first end portion 22 can be directly connected and permanently fixed by adhesive, ultrasonic lamination, hot pressing, etc. to improve the tightness of the connection between the exhaust net and the first end portion 22; when the exhaust channel 4 is an exhaust hole (such as Figure 7), that is, a plurality of teardrop-shaped exhaust holes are evenly and evenly spaced at the first end 22 of the gas delivery hose 2, the orientation of the plurality of teardrop-shaped exhaust holes is consistent with the extension direction of the tube body of the first end 22, and the end with a larger diameter of the teardrop-shaped exhaust hole is close to the fixed port 11, and the end with a larger diameter is arranged toward the fixed port 11, which can reduce the distance from the fixed port 11 to the exhaust channel 4, thereby improving the exhaust efficiency of the exhaust gas. The distribution and size of the exhaust holes are not unique, and in other embodiments, exhaust holes of other shapes, such as square holes or triangular holes, can also be used. The setting of the exhaust holes can improve the convenience of setting the exhaust channel 4, and there is no need to add redundant components, thereby reducing the weight of the frame assembly and easily realizing the exhaust of the exhaust gas, which is beneficial to the timely gas exchange of the user; when the exhaust channel 4 is a combination of the exhaust hole and the noise reduction member 7 (such as Figure 8 ), it is only necessary to add a noise reduction component 7 at the position of the exhaust hole, the noise reduction component 7 covers the exhaust hole and is wrapped around the side wall of the first end portion 22, so as to reduce the sound of gas flow when the user exhales. According to the test method in ISO 17510, when the exhaust hole is used alone, the sound decibel is about 40-50 decibels. After adding the noise reduction component 7, the sound decibel is about 19-30 decibels, and the noise can be reduced by 10-30 decibels. The frame assembly has a good noise reduction effect. The noise reduction component 7 can be noise reduction cotton or cloth; the material of the noise reduction cotton can be made of one of polyester, polypropylene, polyethylene, nylon, vinylon and natural fabric; the connection method of the noise reduction component 7 and the exhaust channel 4 can be a permanent fixation method such as adhesive, ultrasonic pressing, hot pressing, etc., or it can be connected by a disassembly method such as snaps.

[0120] Example 3

[0121] This embodiment provides a frame assembly without an elbow. The difference between the third embodiment and the first embodiment lies in the location of the exhaust passage 4.

[0122] The frame assembly also includes an exhaust connector 5, which includes a first connector 51 connected to the fixing port 11 and a second connector 52 connected to the first end 22. The first connector 51 is detachably connected to the frame 1 through the fixing port 11, and the second connector 52 is detachably connected to the gas hose 2 through the first end 22 (such as Figure 10 The cross-sectional profile of the exhaust connector 5 needs to include at least one shape that matches the joint of the fixing port 11 on the frame 1, and at least one shape that matches the joint of the first end 22 of the gas hose 2; at least two parts of the exhaust connector 5 can be slightly deformed, and the materials include but are not limited to polypropylene, polycarbonate, polyethylene, silicone, thermoplastic materials, etc.; the overall length of the exhaust connector 5 is about 10-25mm, the outer diameter is about 20-28mm, the wall thickness is about 1-3mm, and the weight is about 1-10g. The exhaust channel 4 is provided on the side wall of the exhaust connector 5 (such asFigure 9 ), the ventilation area accounts for 20%-50% of the surface area of ​​the first end 22, the exhaust channel 4 can be any one of an exhaust net, an exhaust hole, or a combination of an exhaust hole and a noise reduction member 7. When the exhaust channel 4 is an exhaust net (such as Figure 9 The exhaust net is coated on the side wall of the first joint 51, and the exhaust net can be made of materials such as polyvinyl chloride, polypropylene, polytetrafluoroethylene or nylon; the exhaust net and the first joint 51 can be directly connected and permanently fixed by adhesive, ultrasonic lamination, hot pressing, etc. to improve the tightness of the connection between the exhaust net and the first joint 51; when the exhaust channel 4 is an exhaust hole (such as Figure 9 On the left side), that is, a plurality of water drop-shaped exhaust holes are evenly and evenly spaced at the first end 22 of the gas delivery hose 2, and the direction of the plurality of water drop-shaped exhaust holes is consistent with the extension direction of the tube body of the first end 22, and the end with a larger diameter of the water drop-shaped exhaust hole is close to the fixed port 11. The end with a larger diameter is arranged toward the fixed port 11, which can reduce the distance from the fixed port 11 to the exhaust channel 4, thereby improving the exhaust efficiency of the exhaust gas. The distribution and size of the exhaust holes are not unique, and in other embodiments, exhaust holes of other shapes, such as square holes or triangular holes, can also be used. The setting of the exhaust holes can improve the convenience of setting the exhaust channel 4, and there is no need to add extra components, reduce the weight of the frame assembly, and easily realize the exhaust of the exhaust gas, which is conducive to the timely gas exchange of the user; when the exhaust channel 4 is a combination of an exhaust hole and a noise reduction member 7, it is only necessary to add the noise reduction member 7 at the position of the exhaust hole, and the noise reduction member 7 covers the exhaust hole and is wrapped around the side wall of the first joint 51, thereby reducing the sound of the gas flow when the user exhales the gas, according to ISO According to the test method in 17510, when the exhaust hole is used alone, the sound decibel is about 40-50 decibels. After adding the noise reduction component 7, the sound decibel is about 19-30 decibels, and the noise can be reduced by 10-30 decibels. The noise reduction effect of the frame assembly is better. The noise reduction component 7 can be noise reduction cotton or cloth; the material of the noise reduction cotton can be made of one of polyester, polypropylene, polyethylene, nylon, vinylon and natural fabric.

[0123] The respiratory mask with foam pad implementing the present invention has at least the following beneficial effects:

[0124] 1) Reduce components and reduce weight: Most mask systems on the market use frames, elbows, catheters and straps to connect the patient interface pad with other tubular connectors to form a complete gas delivery channel to deliver pressurized gas to the patient's airway to prevent apnea. When the mask system is worn for a long time at night, the weight of the mask system may oppress the user, causing some users to feel uncomfortable and causing sleep obstructions such as indentation and psychological pressure. Therefore, our product creatively constructs the frame assembly into three parts - frame, gas hose and side connector, and combines the redesign of the nasal pillow to form a new nasal mask system. In the new frame assembly, the frame is designed to be directly connected to the gas hose, and the exhaust channel on the elbow is redesigned in combination with the frame assembly, removing the traditional elbow component and setting an exhaust channel on the frame, which can be combined with noise reduction materials. Such a design can not only reduce the noise of the product and ensure that the product provides a quiet use environment for users when in use, but also reduce the overall weight of the assembly, making it more comfortable to wear, and improving the user's comfort and user experience.

[0125] 2) Simplify the user's usage: The connection between the gas hose and the frame is a detachable connection, which simplifies the installation process and allows users to quickly disassemble and wear the mask system, avoiding the situation where the user needs to get up at night or move quickly in case of an emergency and cannot separate the mask from the machine in time. The second end of the gas hose can also rotate 360°; compared to the current permanent connection between the gas hose and the frame, the detachable and rotatable structure can reduce the probability of the gas hose being tangled due to the two ends being fixed, greatly improving the flexibility and adaptability of the frame assembly. In addition, the detachable pipe also provides users with more convenient cleaning and replacement options. Users can clean and maintain it regularly to keep the mask system in good condition and avoid potential health risks.

[0126] 3) More economical and environmentally friendly for users: The application of detachable hoses can bring us many economic and environmental advantages. Due to the special nature of the hose, its material is more easily damaged than other components of the assembly. For users, this detachable design allows that when the gas hose or other components are damaged during use, only the damaged part needs to be replaced separately, without having to replace the entire frame assembly. This reduces the cost of use and maintenance costs and extends the service life of the entire system, improves the service life and reusability of the gas hose, and makes the maintenance and repair of the entire frame assembly more efficient, more economical and environmentally friendly.

[0127] 4) Convenient manufacturing for producers: From a production perspective, the use of a detachable connection structure for production and assembly can avoid the problem of easy damage caused by traditional welding or fixed connection production of one-piece frame hoses, thereby reducing the defective rate; when it is necessary to inspect or replace damaged parts, only simple mechanical disassembly is required for rapid inspection operations, ensuring the continuous stability of the production process; through this simple mechanical structure, the operating efficiency of the production line is maintained, bringing a more efficient and reliable production process to the manufacturer.

[0128] 5) Improved comfort: To improve wearing comfort, we have given special consideration to the design of the side connector. In order to adapt to facial deformation, we selected a deformable material with support and adopted an integrated injection molding process to avoid facial discomfort caused by connection marks. The overall side connector presents a smooth arc shape, which better fits the deformation of the user's face and provides a more comfortable wearing experience. A variety of connection options are provided, including buckles, snaps, Velcro, knobs, magnetic suction, etc., to achieve flexible connection with the frame. In order to further improve the usability of the product, the L / R embossed logo, that is, the left and right logo, is marked on the book strap to help users wear the nasal mask more conveniently and quickly in dark environments, providing users with a more intelligent and convenient use experience.

[0129] In summary, our product creatively constructs the frame assembly into a combination of three parts (frame, gas hose and side connector), which maintains the main functions of the product while achieving a better user experience, improving the overall comfort of the product, making it easier to clean, and also greatly extending the overall service life of the product. In addition, the detachable design can effectively reduce production costs and make a positive contribution to environmental protection. The disassembly structure combination and manufacturing process make the production process more efficient and economical, reducing resource waste; at the same time, its detachable and reusable characteristics are also conducive to reducing waste generation and being more environmentally friendly. Overall, this product design of a frame assembly without elbows not only improves functionality and user experience, but also takes into account comfort and environmental protection, which will bring users a more convenient, efficient and sustainable user experience.
