In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0030] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0031] The nasal pillow is a mask for treating sleep apnea. The existing nasal pillow includes a nasal pillow support component with an air outlet and an air inlet, a headband connecting the two sides of the nasal pillow support component, and a curved tube connected to the inlet end of the nasal pillow support component. When the user uses it, the nasal pillow will be installed and matched with the ventilator, and then the air outlet end of the nasal pillow will be directly placed at the edge of the user's nostrils to deliver pressurized gas into the nasal cavity.

[0032] On the one hand, when using the existing nasal pillow, if the curved tube or the nasal pillow supporting component is subjected to external force, the nasal pillow supporting component may easily fall off the user's nose, thereby causing poor pressurized air supply effect of the nasal pillow.

[0033] On the other hand, the existing nasal pillow adopts the form of a nasal pillow body equipped with a headband, which also has the following disadvantages: 1) The headband has a strong sense of restraint: Most of the existing positive pressure ventilation nasal pillows are equipped with a fabric composite headband, which will give the head a serious foreign body sensation when worn, and the material is relatively hard and does not fit the face well. The structure is complex and the cost is too high, which brings more economic burden to users. 2) The headband is not aesthetically pleasing: After using the existing positive pressure ventilation nasal pillow, the user will form an indentation on the head when taking off the headband, which affects the appearance. 3) The risk of infection is high: The existing technical solution requires users to use it for a long time and needs to contact the nasal mucosa all night. If it cannot be cleaned as required, there will be a risk of upper respiratory tract infection, and it usually needs to be replaced after long-term use for 3-6 months. 4) High cost: The unit price of the fabric composite headband is high, and the user's procurement cost is high.

[0034] In order to solve the above problems, the utility model provides a face-fitting nasal pillow. The entire nasal pillow can be firmly attached to the user's nose without falling off, and no headband is required. It has the advantages of high fit, good comfort, no indentation, no impact on appearance, low production cost, no need for cleaning and disinfection, and low maintenance cost.

[0035] Please also read Figure 1 to Figure 2 In this embodiment, the face-to-face nasal pillow 100 at least includes a nasal pillow supporting component 1, a fitting component 2, a magnetic suction component 3 and a nasal plug component 8, wherein:

[0036] The nasal pillow support component 1 includes a support body and two air outlet ends 11 and an air inlet end 12 arranged on the support body. The two air outlet ends 11 and the air inlet end 12 are located on opposite sides of the support body. An air transmission chamber connecting the two air outlet ends 11 and the air inlet end 12 is arranged inside the support body.

[0037] It should be noted that the nasal pillow is a type of ventilator mask that contacts a small area of ​​the face. When in use, the support body is mainly against the user's nose and lips. At this time, the two air outlets 11 on the support body correspond to the two nostrils of the user, but the air outlets 11 do not extend into the nostrils. The material of the support body can be an elastic material, so that the support body can adapt to the face shape of different users and has a wider adaptability.

[0038] It should also be noted that the nasal pillow support component 1 can be formed by one-step injection molding, that is, the two air outlet ends 11 and the air inlet end 12 are of an integrated design with the support body.

[0039] like Figure 1 As shown, the nasal pillow support component 1 includes a support body, the outer shape of the support body is a curved surface design, an air inlet end 12 is provided on one side of the support body, and two inclined air outlet ends 11 are provided on the other side of the support body.

[0040] In this embodiment, the fitting component 2 includes a relative front and back surface. The front surface of the fitting component 2 is fixed on the supporting body, and the back surface is adhered to the outer edge of the nostril and the cheeks on both sides of the nose. The fitting component 2 is also provided with an avoidance hole 21 that passes through the fitting component 2.

[0041] It should be noted that the fitting component 2 is sticky, and the material of the fitting component 2 can be selected from any one of silicone, non-woven fabric and hydrogel. Usually, an isolation layer is also provided on the fitting component 2 to prevent the fitting component 2 from sticking to the surface of other objects before use, which causes the fitting component 2 to be unable to be used normally. When in use, the isolation layer on the fitting component 2 can be torn off, and then the fitting component 2 can be attached to the nose and cheek of the user. The provision of the fitting component 2 enables the air inlet end 12 of the nasal pillow support component 1 to be firmly attached to the user's nose without falling off.

[0042] It should also be noted that the fitting component 2 replaces the traditional headband to achieve a headband-free design for the nasal pillow. On the one hand, the fitting component 2 is cheaper to produce than the headband. On the other hand, the fitting component 2 has no indentation and does not affect the appearance. In addition, the fitting component 2 is disposable and does not require cleaning. Each time the fitting component 2 is used, it is a clean product, eliminating safety risks such as cross-infection and cleaning and disinfection. In addition, the provision of the fitting component 2 also ensures that the nasal pillow support component 1 has no part that directly contacts the user's nasal mucosa, so there is no need to clean and disinfect the nasal pillow support component 1, and the maintenance cost is low.

[0043] like Figure 1 and Figure 3 As shown, the fitting component 2 is V-shaped in appearance, and comprises two symmetrically arranged fitting units, each of which is provided with a avoidance hole 21 .

[0044] In this embodiment, there are two nasal plug components 8, which are arranged on the back of the fitting component 2 and extend into the nostrils. The nasal plug component 8 is provided with an air delivery hole 81 penetrating the nasal plug component 8, and the air delivery hole 81 is connected to the air outlet end 11. The nasal plug component 8 extends into the nostrils to achieve close adhesion to the nostrils, thereby improving the sealing effect.

[0045] It should be noted that the nasal plug component 8 and the fitting component 2 can be of an integrated design. For example, the nasal plug component 8 is formed on the fitting component 2 by secondary injection molding. The nasal plug component 8 and the fitting component 2 can also be of a split design. For example, the nasal plug component 8 is on the supporting body through the fitting component 2.

[0046] It should also be noted that the material of the nasal plug component 8 can be an elastic material, so that the nasal plug component 8 can adapt to the nostril shapes of different users and has a wider adaptability.

[0047] It should also be noted that the present embodiment does not limit the shape of the nasal plug component 8. The size of the nasal plug component 8 can be customized according to actual needs. Different models and specifications of nasal plug components 8 can also be designed to suit different users.

[0048] like Figure 1 and Figure 3 As shown, the shape of the nasal plug component 8 is conical, and the diameter of the air delivery hole 81 inside the nasal plug component 8 gradually decreases along the extension direction. This design can make the shape of the nasal plug component 8 roughly the same as the internal contour of the user's nostrils, which is more comfortable.

[0049] In this embodiment, the magnetic attraction component 3 includes a first magnetic attraction component 31 and a second magnetic attraction component 32. The first magnetic attraction component 31 is arranged on the supporting body, and the second magnetic attraction component 32 is arranged on the fitting component 2, and the first magnetic attraction component 31 and the second magnetic attraction component 32 are fixed by adsorption. The supporting body is adsorbed and fixed on the fitting component 2 by the adsorption force between the first magnetic attraction component 31 and the second magnetic attraction component 32.

[0050] It should be noted that the first magnetic component 31 and the supporting body can be an integral design. For example, the first magnetic component 31 is molded on the supporting body by secondary injection molding. The first magnetic component 31 and the supporting body can also be designed as split parts. For example, the first magnetic component 31 is bonded to the supporting body by glue. Similarly, the second magnetic component 32 and the fitting component 2 can be an integral design. For example, the second magnetic component 32 is molded on the fitting component 2 by secondary injection molding. The second magnetic component 32 and the fitting component 2 can also be designed as split parts. For example, the second magnetic component 32 is bonded to the fitting component 2 by glue.

[0051] It should also be noted that the present embodiment does not limit the materials of the first magnetic member 31 and the second magnetic member 32. For example, the material of the first magnetic member 31 is a magnetic metal, and the material of the second magnetic member 32 is a magnetic material. For example, the material of the second magnetic member 32 is a magnetic metal, and the material of the first magnetic member 31 is a magnetic material. The aforementioned magnetic metal is a basic substance of a single element, which may be but is not limited to iron, while the aforementioned magnetic material is a product of a mixture of multiple substances, which may be but is not limited to ferrite magnetic materials, aluminum nickel cobalt magnetic materials, neodymium iron boron magnetic materials and other materials.

[0052] It should also be noted that the present embodiment does not limit the shapes of the first magnetic member 31 and the second magnetic member 32 , which may be annular or in other shapes.

[0053] like Figure 1 , Figure 2 and Figure 3 As shown, the first magnetic member 31 and the second magnetic member 32 are ring-shaped. The first magnetic member 31 is a first magnetic ring bonded to the supporting body and sleeved on the outside of the air outlet end 11, and the second magnetic member 32 is a second magnetic ring bonded to the fitting component 2 and surrounding the avoidance hole 21.

[0054] In this embodiment, the face-to-face nasal pillow 100 further includes a limiting component 4, which is disposed between the first magnetic component 31 and the second magnetic component 32. The setting of the limiting component 4 can ensure that the first magnetic component 31 and the second magnetic component 32 are accurately matched when connected, and prevent the magnetic component 3 from being offset when connected.

[0055] It should be noted that the present embodiment does not limit the shape of the limiting component 4, which may be annular or in other shapes.

[0056] like Figure 3 As shown, the limiting component 4 is a limiting ring, which is installed on the second magnetic member 32. The setting of the limiting ring can prevent the first magnetic member 31 and the second magnetic member 32 from being offset when connected.

[0057] In this embodiment, the face-to-face nasal pillow 100 further includes a curved pipe 5, a fixed shell 6 and a sealing ring 7. The curved pipe 5 is a connecting pipe connected to the ventilator, and the fixed shell 6 can be used as a curved pipe interface to fix the nasal pillow support component 1 at the same time. The fixed shell 6 or the nasal pillow support component 1 is also provided with a receiving groove for the fixed sealing ring 7. The number of the sealing ring 7 can be one or two. The setting of the sealing ring 7 can realize a sealed connection between the fixed shell 6 and the nasal pillow support component 1, and prevent the pressurized gas from the ventilator from leaking at the connection between the fixed shell 6 and the nasal pillow support component 1.

[0058] like Figure 3As shown, the curved tube 5 and the nasal pillow support component 1 are respectively sleeved at the sleeve openings on both sides of the fixed shell 6, and the setting of the fixed shell 6 realizes the connection between the curved tube 5 and the nasal pillow support component 1. At the same time, a sealing ring 7 is installed inside the air inlet end 12 on the support body, so that the air inlet end 12 on the support body is sealed and connected with the sleeve opening of the fixed shell 6.

[0059] For ease of understanding, this embodiment also introduces the following operation process of using the face-to-face nasal pillow 100:

[0060] The user or medical staff opens the product packaging and there are two parts, such as Figure 4 As shown, one part is the assembled curved tube 5, the fixed shell 6 and the nasal pillow support component 1 with the first magnetic component 31, and the other part is the fitting component 2 with the second magnetic component 32 and the nasal plug component 8.

[0061] The user needs to first clean the grease on the cheeks or nose, then tear off the isolation layer on the back of the fitting part 2, and then insert the nose plug part 8 on the fitting part 2 into the user's nostrils, adjust it to a comfortable position, and also stick the fitting part 2 to the position of the outer edge of the nostrils, and fix it on the cheeks on both sides of the nose, and try to avoid bubbles. It can be seen that when in use, the nose plug part 8 extends into the nostrils to achieve primary sealing, and the fitting part 2 covers the outer edge of the nostrils and part of the cheeks to provide sealing support.

[0062] The first magnetic component 31 on the nose pillow support component 1 is brought close to the second magnetic component 32 on the fitting component 2, and the nose pillow support component 1 is adsorbed to the fitting component 2 through the magnetic attraction force between the first magnetic component 31 and the second magnetic ring. The second magnetic component 32 is provided with a limiting component 4 (i.e., a limiting ring) to ensure that the positions of the first magnetic component 31 and the second magnetic component 32 can be accurately matched when they are connected.

[0063] Finally, connect the curved tube 5 to the ventilator, start the ventilator to detect whether the face-fitting nasal pillow 100 is leaking. If there is leakage at the fitting point between the fitting part 2 in the face-fitting nasal pillow 100 and the user's nostrils, the fitting part 2 needs to be re-fixed.

[0064] The surface-fitting nasal pillow provided by the utility model is a connection interface between a non-invasive positive pressure ventilation device and a user. The nasal plug component is extended into the nostrils to achieve primary sealing, and the fitting component is adhered to the outer edge of the nostrils and the cheeks on both sides of the nose to further achieve sealing and better fixation, so that the nasal pillow supporting component is firmly attached to the user's nose and does not fall off, thereby improving the pressurized air supply effect of the nasal pillow.

[0065] At the same time, the utility model adopts a fitting component to replace the traditional headband, which can effectively get rid of the constraints brought by the traditional headband, and the production cost of the fitting component is lower. There is no indentation on the face of the user after tearing off the fitting component, which does not affect the appearance; in addition, the fitting component is disposable and needs to be replaced by a new one after use by the user. Moreover, the arrangement of the fitting component makes it possible for the nasal pillow support component to have no part that directly contacts the user's nasal mucosa, and there is no need to clean and disinfect the nasal pillow support component, and there is no need to worry about cross infection and cleaning and disinfection, and the maintenance cost is also low; in addition, the fitting component and the nasal pillow support component are connected by magnetic attraction, which is convenient for replacement and disposal, and the operation is more convenient; in addition, a limiting component is provided between the first magnetic component and the second magnetic component, and the first magnetic component and the second magnetic component are precisely matched after being connected.

[0066] Therefore, the face-fitting nasal pillow provided by the utility model can be firmly attached to the user's nose without falling off, and at the same time has the advantages of no headband, effectively getting rid of the constraints brought by traditional headbands, convenient and quick operation, simple and easy to use, preventing cross infection, lower cost, etc., and can provide a breathing channel for the user safely and comfortably.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
