Description

Technical Field

[0001] The utility model is a nasal mask that seals the area from the user's nose tip to the upper lip, is used to surround a part of the user's nose and deliver pressurized gas from a ventilator into the user's nasal airway to treat obstructive sleeping disorders, and mainly includes a rigid part, a flexible part, a spring structure and an exhaust port. Background Art

[0002] Sleep is absolutely necessary for everyone and is a need of life. At the same time, sleep is also a cyclical physiological phenomenon. Nowadays, many people are in a sub-healthy state and are prone to fatigue. With the increasing number of overweight and obese people and the increasingly serious social problems of an aging population, more and more people have sleep disorders, making the incidence of sleep apnea a common problem worldwide, with different incidences in different regions and populations. Sleep apnea includes many different types, the most common of which is obstructive sleep apnea syndrome (OSA). According to the research report, from 2015 to 2019, the number of people aged 30-69 with obstructive sleep apnea worldwide increased from 980 million to 1.05 billion. It is estimated that by 2024, the number of people with obstructive sleep apnea worldwide will increase to about 1.15 billion, which does not include patients under 30 and over 69 years old. Obstructive sleep apnea syndrome, also known as obstructive sleep apnea, refers to the phenomenon of repeated respiratory arrest and hypoventilation during sleep. Clinically, it can be manifested as snoring, loud and irregular snoring, a feeling of suffocation at night, sleep disorders, daytime drowsiness, memory loss, and in severe cases, decreased cognitive function and abnormal behavior. It can be seen that people's rhythm of life is gradually affected by sleep apnea.

[0003] Continuous positive airway pressure (CPAP) therapy is a common treatment for obstructive sleep apnea syndrome, that is, maintaining the openness of the user's airway through positive pressure ventilation to reduce the user's apnea and snoring conditions, improve the user's sleep quality and the user's quality of life. It usually has components such as a ventilator, a hose, an elbow, a frame and a patient interface device. The treatment process is roughly to generate a constant pressurized airflow through a ventilator used for continuous positive airway pressure therapy. The pressurized airflow is delivered to the heating tube or hose through the ventilator tube and then to the patient interface device through components such as elbows and frames, and finally to at least one airway of the user. During this process, the patient interface device is configured to directly contact the user's face. It is a very important accessory that needs to take into account a variety of human body sensations. Compared with components such as elbows and frames, it also has more considerations. The design of the patient interface device must not only consider the coordination between components and whether the continuous positive pressure gas can be accurately and stably sealed, but also the user's comfort when in contact with the user's face.

[0004] There are roughly two major types of patient interface devices on the existing market for sealing the user's nasal airway to meet the different preferences and needs of users, namely, invasive nasal mask patient interface devices and non-invasive nasal mask patient interface devices. The invasive nasal mask patient interface device is a relatively small nasal mask with two small protrusions protruding to one side, and its material is usually silicone or rubber. When in use, the two small protrusions are inserted into the nostrils, which will have better sealing than non-invasive nasal masks. However, since the two protruding parts at the air outlet end enter the first nostril and the second nostril entrance of the user, some users will feel uncomfortable because there are foreign objects in the nostrils when using it, and therefore are not accustomed to wearing such sleep apnea components. The invasive nasal mask also has high requirements for the sealing structure and has many uncertainties that cannot guarantee its sealing. Therefore, for most users, the invasive nasal mask is not the best choice.

[0005] Non-invasive nasal masks reduce the user's sensory characteristics because they do not require part of the nasal mask to enter the user's nostrils, so the user will be relatively comfortable when using them. However, they also have shortcomings compared to invasive nasal masks. For example, non-invasive nasal masks have a larger volume than invasive nasal masks because they surround the outside of the user's nostrils, which has a certain impact on the convenience of the nasal mask. They are also heavier than invasive nasal masks. Compared with invasive nasal masks, the user's sense of pressure on the nose is increased when wearing them. In addition, since the uprightness of different people's noses is different, the existing non-invasive nasal masks do not have corresponding sizes or flexible parts that can adapt to different nose uprightness. As mentioned above, both invasive nasal masks and non-invasive nasal masks have advantages and disadvantages, and the current market does not have a comprehensive nasal mask that combines the advantages of invasive nasal masks and non-invasive nasal masks and abandons their respective disadvantages to provide better treatment comfort for patients with obstructive sleep apnea and achieve better treatment effects.

[0006] Based on the above findings, the utility model designs a nasal mask that seals the area from the nose tip to the upper lip, which combines the advantages of an invasive nasal mask patient interface device and a non-invasive nasal mask. The nasal mask not only has the advantages of being more comfortable to wear, small in size and easy to carry, light in weight and less oppressive, but also has a spring structure that can be adjusted according to the different nose uprightness of the user. This spring structure will improve the adaptability of the nasal mask and make the sealing of the entire nasal mask better. In addition, the nasal mask designed by the utility model can have two ways of adapting one air inlet end and two air inlet ends, so as to provide users with more options. Utility Model Content

[0053] A nose mask that seals the area from the nose tip to the upper lip of the user according to the present invention has at least the following features:

[0054] Beneficial effects:

[0055] 1) Compared with the existing non-invasive nasal masks on the market that seal the area below the nose tip to the upper lip, the nasal mask designed by the utility model has better sealing performance. Because the size and height of different people's noses are always different, and the existing non-invasive nasal masks often seal the user's face through two openings that contact the surface where the nostrils are located to transmit continuous positive pressure airflow. Because different people's noses are different in height, size and other aspects, the two openings of the existing nasal masks cannot fully adapt to the nasal airways of most people, and are prone to leakage and other problems. Therefore, the utility model designs a nasal mask that seals the area from the nose tip to the upper lip. The sealing of the nasal mask includes the nose tip. The invention relates to a non-invasive nasal mask for use with an invasive nasal mask. The non-invasive nasal mask has a spring structure at the point where the first opening for outputting continuous positive pressure airflow contacts the nose tip, and the spring structure helps to make adjustments according to the differences in the noses of different users, thereby solving the shortcoming that the non-invasive nasal mask is less effective in treatment due to poor sealing and easy leakage compared to the invasive nasal mask. That is, there will be no gas leakage due to mismatch with the user's nose, and not only better sealing is achieved, but also the discomfort or foreign body sensation inside the nostrils that the user may feel is reduced, thereby improving the user's comfort and reducing the interruption of treatment or the user's non-compliance with the treatment plan due to the user's discomfort.

[0056] 2) Compared with the existing nasal masks on the market that seal from the bridge of the nose to the upper lip area, the nasal mask designed by the present invention has a smaller area, lighter weight, and better convenience. The nasal mask designed by the present invention adjusts the sealing area to seal from the user's nose tip to the upper lip area, which reduces the volume compared with existing similar nasal masks. The smaller nasal mask is easier for users to wear and easier to adjust when the nasal mask is displaced, which reduces the risk of gas leakage to a certain extent. In addition, due to its smaller volume, the nasal mask of the present invention is more convenient for users to carry and store when traveling, which facilitates the continuity of treatment. At the same time, the wearing comfort is improved due to the reduced contact area with the user. Compared with existing nasal masks, smaller nasal masks usually do not block the user's field of vision. Therefore, users can more easily perform activities such as reading when wearing them.

[0057] 3) Compared with invasive nasal masks, the nasal mask designed by the utility model is more comfortable, less burdensome to the nostrils, and more inclusive. The nasal mask designed by the utility model does not enter the first nostril and the second nostril entrance of the user at the air outlet end, thereby reducing the sensory interference to the user, and is more suitable for most people, especially for those who are not accustomed to wearing sleep apnea components, making it easier for such people to adapt to wearing treatment equipment components. In addition, the size of invasive nasal masks is difficult to match the nostril size of most users. Compared with invasive nasal masks, the non-invasive nasal mask designed by the utility model only needs to meet the size of the first opening to surround the user's nasal airway. Users feel more comfortable when using it, have less burden on the nostrils and are more inclusive, have less sensory interference, and make it easier for users to fall asleep.

[0058] 4) The air inlet end of the nose mask designed by the utility model can be designed to have different air inlet end forms. The user can choose to have air inlet through two ports on both sides or through one port in the middle. The user has a wide range of choices and can adapt to different forms, simplifying the product and reducing production and R&D costs. The nose mask shown in the utility model has flexibility for the air inlet of the positive pressure airflow. The same flexible part in contact with the user's face can be adapted to different joint parts with an air inlet or joint parts with air inlets on both sides. The technical features of the existing products are expanded to facilitate users to choose and replace according to their own needs or preferences, giving users more room for choice, so that the design of the utility model can adapt to new needs and changes in the market. In addition, the independent development and testing of the flexible part in contact with the user's face compared to the design and development of the entire respiratory accessory reduces the complexity of the product as a whole and reduces the degree of risk of the entire product, making the production method and cost simpler and cheaper. Correspondingly, the utility model also reduces the R&D cost of the product. BRIEF DESCRIPTION OF THE DRAWINGS

[0080] In order to facilitate the understanding of the utility model, the utility model will be described more fully below with reference to the relevant drawings. Typical embodiments of the utility model are given in the drawings. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and comprehensive.

[0081] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the utility model. The terms used in the utility model specification herein are only for the purpose of describing specific embodiments and are not intended to limit the utility model.

[0082] The present invention recognizes that the adaptability of the invasive nasal mask 1 on the existing market has certain limitations on the population and has a strong sense of interference to the user, and the non-invasive nasal mask 1 on the existing market also has the disadvantages of being too large and having poor sealing stability. In view of the above problems, the present invention designs a nasal mask 1 that seals the user's nose tip to upper lip area, and adds a spring structure 23 to the flexible part 2. The use of the spring structure 23 enables the nasal mask 1 of the present invention to be adjusted and adapted according to the user's nose, thereby improving its sealing stability. Since only the first opening 12 in contact with the user's face needs to surround the user's nasal airway, it is suitable for almost all noses of different heights and sizes, and the small size makes it convenient for users to carry it outside for continuous treatment and timely adjustment when displacement occurs. The innovative design of the present invention improves the flexibility of the product and has a positive impact on patients with obstructive sleep apnea.

[0083] Several structures of a nose mask for sealing the area from the nose tip to the upper lip of a user according to the present invention are described below in conjunction with specific examples.

[0084] Example 1

[0085] This embodiment provides a nasal mask 1 that seals the area from the tip of the nose to the upper lip of the user. This embodiment provides a 3D schematic diagram, a usage scenario diagram, a sealing range display diagram, an exploded diagram, and a cross-sectional structure diagram of a nasal mask that seals the area from the tip of the nose to the upper lip of the user. Figure 1-11 The nose mask 1 shown in this embodiment has a flexible part 2, which is bent toward a side close to the user's face and forms at least one protrusion 22 to form a chamber 14 for containing gas, and has a first opening 12 facing the user's face and at least a second opening 13 away from the user's face, wherein the second opening 13 is constructed and arranged as an air inlet to receive a continuous positive pressure airflow into the flexible part 2, wherein the flexible part 2 includes a sealing part 21, and the sealing part 21 is constructed as a wall formed by the protrusion 22 extending at the first opening 12, and is arranged to surround the user at least including the nose tip and the first nostril and the second nostril area when in use and to abut against the surface around the nostrils (such as Figure 3 , Figure 4As shown in the figure, this method has obvious advantages in the existing market. In terms of form, it is between the nasal mask that seals the user's nose tip to the upper lip and the nasal mask that only seals the user's nose from below the nose tip to the upper lip. Because it surrounds the user's nose tip, there will be no situation where the nasal mask 1 and the user's nose are not compatible due to differences in nose height and size. The nasal mask 1 of the utility model only needs to ensure that the opening of the nasal mask 1 that contacts the user's face surrounds the user's nasal airway, without worrying about the opening being too large or too small or the opening being misaligned with the user's nostrils and easily shifting. The utility model is different from the non-invasive nasal mask 1 on the existing market that seals the user's nose from below the nose tip to the upper lip area. In addition to sealing the user's nose tip to the upper lip area, its sealing portion 21 is also constructed so that it does not position or interfere with the user's columella when sealing with the user's face (such as Figure 4 As shown), this method increases the user's rapid adaptation to the nasal mask 1 by reducing the fitting range of the sealing part 21 to the user's face. This method is non-invasive. Compared with the invasive nasal mask 1, it reduces the foreign body sensation of the user when using the nasal mask 1, and is more comfortable when used, thereby increasing the patient's compliance with the treatment.

[0086] The sealing portion 21 has at least one thin area 212 and a support area 213 thicker than the thin area 212, which together form the wall of the sealing portion 21. When in use, the sealing portion 21 in the flexible portion 2 contacts the user's face and forms a seal. In order to ensure the strength of the sealing portion 21 supporting the face and make the sealing portion 21 contacting the face more comfortable for the user, a part of the wall of the sealing portion 21 is designed to be thickened to form the support area 213, and the remaining part is used as the thin area 212 (such as Fig. 9 As shown in the figure, the area of ​​the support area 213 of the sealing part 21 of the partial nasal mask 1 is larger than the area of ​​the thin area 212, so as to provide effective and stable support for the sealing part 21 of the nasal mask 1. In the form of the partial nasal mask 1 in the embodiment, in order to ensure the appearance of the sealing part 21 of the nasal mask 1, the sealing part 21 can be set to have a uniformly varying wall thickness, and the thin area 212 is gradually extended from the thicker wall. In this way, the support area 213 of the sealing structure has more than one wall thickness (such as Fig.10 shown).

[0087] In another embodiment, the nasal mask 1 is provided with an air inlet, and the nasal mask 1 can cooperate with the elbow, the frame and other components, and is configured to receive a continuous positive pressure airflow into the nasal mask 1 (such as Fig.11 shown).

[0088] Example 2

[0089] This embodiment provides a nasal mask 1 that seals the area from the tip of the nose to the upper lip of the user, as shown in FIG. Figure 12-13 This embodiment provides a three-dimensional schematic diagram of a patient interface device. Figure 12-13In the embodiment of the utility model shown, the difference from the nasal mask 1 in the first embodiment is that the nasal mask 1 includes a rigid part 3, which is connected to the second opening 13 of the flexible part 2 away from the user's face, and is configured and constructed to form a connection with other sleep disorder treatment components. The rigid part 3 has at least two connection ports 31, one of which is constructed to connect with the second opening 13 of the flexible part 2 away from the user's face, and is sealed with the flexible part 2 to form a chamber 14 containing gas, wherein at least one connection port 31 is constructed as an air inlet for positive pressure airflow to enter the chamber 14, for receiving the positive pressure airflow entering the nasal mask 1. The rigid part 3 has two forms, one of which is a form in which two separate parts are placed on the air inlet end of the nasal mask 1 for receiving the continuous pressurized airflow as the connection port 31 for connection between components. Since the connection port 31 of the rigid part 3 is generally connected to the component by snap-fit, in this case, the rigid part 3 has walls of unequal thickness for connection between the snap-fits (such as Fig.12 As shown in FIG. 1 , another form is as a whole, sealed and connected to the second opening 13 of the flexible part 2 away from the user's face, not only with a connection port 31 connected to the components, but also with a certain internal space for connecting with the flexible part 2 to form a gas storage chamber 14 (as shown in FIG. 1 ). Fig.13 As shown), in this case, the first opening 12 of the rigid part 3 facing the user's face is larger than the second opening 13, wherein the second opening 13 is the opening connecting the rigid part 3 and the flexible part 2. When the nasal mask 1 receives gas, the gas enters from the connection port 31 of the rigid part 3 along the partial inner wall of the rigid part 3 as a path, and then enters the user's nasal airway through the flexible part 2.

[0090] Example 3

[0091] This embodiment provides a nasal mask 1 that seals the area from the tip of the nose to the upper lip of the user, as shown in FIG. Figure 14-16 This embodiment provides a three-dimensional schematic diagram of the patient interface device and a positional relationship diagram of the sealing formation structure and the exhaust port 4. Figure 14-16 In the embodiment of the utility model shown in the figure, the difference from the nose mask 1 in the first embodiment is that the nose mask 1 is provided with an exhaust port 4, having at least one hole opening, for discharging the positive pressure gas in the chamber 14 to the outside through the hole opening, and the hole opening is arranged at a position of the nose mask 1 facing the opening that contacts and seals with the user's face (such as Fig.16As shown in the figure, when the user wears the nose mask 1 to exhaust, the gas first flows out from the user's airway to the sealing part 21. Since the exhaust port 4 is opposite to the sealing part 21, the waste gas can be directly discharged to the outside environment through the exhaust port 4 in a nearly straight line. There are two specific forms, one of which is to directly open small holes with a certain distance from each other at this position. The holes can have a certain taper to disperse the airflow to be discharged from the outside air, which has a certain degree of noise reduction effect. This form is relatively simple (such as Fig.14 As shown in the figure, another form is that a large hole opening for installing an external exhaust component 41 is provided at the position of the opening of the nose mask 1 that contacts and seals with the user's face. The hole opening and the external exhaust component 41 can be connected by a clamping structure, or by friction connection, adhesive connection, or other connection methods such as hot pressing. The external exhaust component 41 can be provided with a noise reduction material 42. When the user wears the nose mask 1 to exhaust, the gas first flows out from the user's airway to the sealing part 21, and then is discharged to the external environment through the external exhaust component 41. The noise reduction effect of the nose mask 1 is achieved by the noise reduction material 42 in the external exhaust component 41, wherein the noise reduction material 42 can be one or more of fiber, foam or granular materials (such as Fig.15 shown).

[0092] Example 4

[0093] This embodiment provides a nasal mask 1 that seals the area from the tip of the nose to the upper lip of the user, as shown in FIG. Figure 17-18 This embodiment provides a three-dimensional schematic diagram of a patient interface device. Figure 17-18In the embodiment of the utility model shown, the difference from the nasal mask 1 in Example 1 is that the nasal mask 1 is provided with a spring structure 23 having a foldable wall, which is located between the flexible part 2 body and the sealing part 21, wherein the spring structure 23 has at least one of the following characteristics: 1. The height of the spring structure 23 is between 5-30 mm; 2. The width of the spring structure 23 is between 3-40 mm; 3. The wall thickness of the spring structure 23 is less than 3 mm. And the spring structure 23 has a wall thickness different from that of the flexible part 2 body and the sealing part 21. Since the sealing part 21 cannot be a completely soft wall, it needs to have a wall of a certain thickness to maintain the shape of the support part to seal the user's face. The flexible part 2 body is mainly used to form a chamber 14 for accommodating gas, and the wall of the spring structure 23 cannot be too thick to facilitate folding the spring structure 23. Therefore, the wall thickness of the spring structure 23 should be thinner than the sealing part 21 and the flexible part 2 body. Because the size and height of different people's noses are always different, the existence of the spring structure 23 on the one hand enables the nose mask 1 to adapt to the noses of users of different heights and sizes, and solves the problem that the two openings of the existing nose mask 1 cannot fully adapt to the nasal airways of most people, and there is a tendency to leak. On the other hand, because the nose tip is higher than other places, the foldable wall of the spring structure 23 enables the nose tip part of the nose mask 1 to have a certain buffer when in use. The setting of the spring structure 23 can relatively reduce the pressure of the sealing part 21 of the nose mask 1 at the nose tip, reducing the discomfort caused to the user by the excessive pressure of the nose mask 1 at the nose tip during use.

[0094] Example 5

[0095] This embodiment provides a nasal mask 1 that seals the area from the tip of the nose to the upper lip of the user, as shown in FIG. Figure 19-21 This embodiment provides a three-dimensional schematic diagram of a patient interface device. Figure 19-21In the embodiment of the utility model shown, the difference from the nasal mask 1 in the first embodiment is that the nasal mask 1 is provided with a comfort layer portion 5, which is constructed and arranged to be attached to at least a portion of the flexible portion 2 and engage the user's face. The use of the comfort layer part 5 makes the nasal mask 1 both durable and comfortable. The part that contacts the face is breathable, so that the skin will not have skin symptoms such as red marks due to long-term wearing, thereby improving the user's compliance with treatment. The material of the comfort layer part 5 can be sponge or cloth, and the comfort layer part 5 and the sealing part 21 can be directly or indirectly connected, wherein the direct connection method includes silicone adhesive, hot pressing, molding, etc. The comfort layer part 5 and the sealing part 21 of the nasal mask 1 can have two fitting methods. Specifically, in one of the fitting methods, the inner edge of the comfort layer part 5 is greater than or equal to the edge of the first opening 12 of the flexible part 2, and when in use, it and the flexible part 2 jointly limit the airflow to enter the user's nasal airway in a sealed manner. In another fitting method, the inner edge of the comfort layer part 5 is smaller than the edge of the first opening 12 of the flexible part 2. When in use, the comfort layer part 5 alone limits the airflow to enter the user's nasal airway in a sealed manner. The fitting of the nasal mask 1 and the comfort layer part 5 includes but is not limited to detachable or non-detachable connections such as glue, hot melting, and welding.

[0096] In addition, the technical features in the above embodiments may be combined as needed to obtain a nasal mask that seals the area from the tip of the nose to the upper lip of the user and includes all or part of the above technical features.

[0097] A nose mask that seals the area from the nose tip to the upper lip of the user according to the present invention has at least the following features:

[0098] Beneficial effects:

[0099] 1) Compared with the existing non-invasive nasal mask 1 on the market that seals the area from below the nose tip to the upper lip, the nasal mask 1 designed by the utility model has better sealing performance. Because the size and height of different people's noses are always different, and the existing non-invasive nasal mask 1 often seals the user's face through two openings that contact the surface where the nostrils are located to transmit continuous positive pressure airflow. Because different people's noses are different in height, size and other aspects, the two openings of the existing nasal mask 1 cannot fully adapt to the nasal airways of most people, and are prone to leakage and other problems. Therefore, the utility model designs a nasal mask 1 that seals the area from the nose tip to the upper lip. The sealing of the nasal mask 1 includes a part of the nose tip. The spring structure 23 is helpful for adjusting according to the differences of noses of different users, and solves the disadvantage that the non-invasive nasal mask 1 is prone to air leakage due to poor sealing compared with the invasive nasal mask 1, that is, there will be no gas leakage due to mismatch with the user's nose, not only achieving better sealing, but also reducing the discomfort or foreign body sensation inside the nostrils that the user may feel, and the user's comfort is also improved, reducing the interruption of treatment due to user discomfort or the user's non-compliance with the treatment plan.

[0100] 2) Compared with the existing nasal mask 1 on the market that seals the area from the bridge of the nose to the upper lip area, the nasal mask 1 designed by the utility model has a smaller volume, lighter weight, and better convenience. The nasal mask 1 designed by the utility model adjusts the sealing area to seal the area from the tip of the nose to the upper lip of the user, which reduces the volume compared with the existing similar nasal mask 1. The smaller nasal mask 1 is easier for the user to wear and easier to adjust when the nasal mask 1 is displaced, which reduces the risk of gas leakage to a certain extent. Moreover, due to its smaller volume, the nasal mask 1 of the utility model is more convenient for the user to carry and store when traveling, which is convenient for achieving continuity of treatment. At the same time, the wearing comfort is improved due to the reduced contact area with the user. Compared with the existing nasal mask 1, the smaller nasal mask 1 usually does not block the user's field of view. Therefore, the user can more easily perform activities such as reading when wearing it.

[0101] 3) Compared with the invasive nasal mask 1, the nasal mask 1 designed by the utility model is more comfortable, less burdensome to the nostrils, and more inclusive. The nasal mask 1 designed by the utility model does not enter the first nostril and the second nostril entrance of the user at the air outlet end, thereby reducing the sensory interference to the user, and is more suitable for most people, especially for those who are not accustomed to wearing sleep apnea components, making it easier for such people to adapt to wearing the treatment equipment components. In addition, the size of the invasive nasal mask 1 is difficult to match the nostril size of most users. Compared with the invasive nasal mask 1, the non-invasive nasal mask 1 designed by the utility model only needs to meet the size of the first opening 12 to surround the user's nasal airway, which will make the user feel more comfortable when using it, less burdensome to the nostrils and more inclusive, with less sensory interference, making it easier for the user to fall asleep.

[0102] 4) The air inlet end of the nose mask 1 designed by the utility model can be designed to have different air inlet end forms. The user can choose to have air inlet through two ports on both sides or through one port in the middle. The user has a wide range of choices and can adapt to different forms, simplifying the product and reducing production and R&D costs. The nose mask 1 shown in the utility model has flexibility for the air inlet of the positive pressure airflow, and the same flexible part 2 in contact with the user's face can be adapted to different joints with an air inlet or joints with air inlets on both sides. The technical features of the existing products are expanded to facilitate users to choose and replace according to their own needs or preferences, giving users more room for choice, so that the design of the utility model can adapt to new needs and changes in the market. In addition, the independent development and testing of the flexible part 2 in contact with the user's face reduces the complexity of the product and the degree of risk of the entire product compared to the design and development of the entire respiratory accessory, making the production method and cost simpler and cheaper. Correspondingly, the utility model also reduces the R&D cost of the product.

[0103] The embodiments of the utility model are described above in conjunction with the accompanying drawings, but the utility model is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the inspiration of the utility model, ordinary technicians in this field can also make many forms without departing from the scope of protection of the utility model and the claims, all of which are within the protection of the utility model.
