Most of the existing positive pressure ventilation nasal pillows adopt the form of a nasal pillow body equipped with a headband, and the nasal pillow body is fixed to the user's face by the headband. The existing nasal pillows have 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 cause a serious foreign body sensation on the head when worn, and the material is relatively hard and the fit to the face is not good. The structure is complex and the cost is too high, which brings more economic burden to the user. 2) The headband is not aesthetically pleasing: After using the existing positive pressure ventilation nasal pillows, when the user takes off the headband, an indentation will be formed on the head, affecting the appearance. 3) High risk of infection: 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.

In order to solve the above problems, the utility model provides a magnetic face-fitting nasal pillow, which does not require a headband and has the advantages of good comfort, no indentation, no impact on appearance, low production cost, no need for cleaning and disinfection, and low maintenance cost.

Please refer to FIG. 1 and FIG. 2 . In this embodiment, the magnetic face-attaching nasal pillow 100 at least includes a nasal pillow supporting component 1, a fitting component 2 and a magnetic component 3, wherein:

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.

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.

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.

As shown in FIG1 , the nasal pillow support component 1 includes a support body having a curved surface. An air inlet end 12 is provided on one side of the support body, and two air outlet ends 11 are inclinedly arranged on the other side of the support body.

In this embodiment, the fitting component 2 is adhered to the outer edge of the nostril and the cheeks on both sides of the nose, and is provided with an escape hole 21 penetrating the fitting component 2 and corresponding to the air outlet end 11.

It should be noted that the fitting member 2 is sticky, and the material of the fitting member 2 can be any one of silicone, non-woven fabric and hydrogel. Usually, an isolation layer is also provided on the fitting member 2 to prevent the fitting member 2 from sticking to other surfaces before use, which may cause the fitting member 2 to be unable to be used normally. When in use, the isolation layer on the fitting member 2 can be torn off, and then the fitting member 2 can be attached to the nose and cheek of the user.

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.

As shown in FIG. 1 , the fitting component 2 is V-shaped in appearance, and includes two symmetrically arranged fitting units, each of which is provided with a avoidance hole 21 .

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.

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.

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.

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.

As shown in Figures 1 and 2, the first magnetic component 31 and the second magnetic component 32 are ring-shaped. The first magnetic component 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 component 32 is a second magnetic ring bonded to the fitting component 2 and surrounding the avoidance hole 21.

In this embodiment, the magnetic nose 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.

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.

As shown in FIG. 3 , 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.

In this embodiment, the magnetic face-fitting nasal pillow 100 further includes a curved pipe 5, a fixed shell 6 and a sealing ring 7. Among them, 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.

As shown in Fig. 3, 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.

For ease of understanding, this embodiment also introduces the use and operation process of the magnetic face-attaching nasal pillow 100 as follows:

When the user or medical staff unpacks the product package, it consists of two parts, as shown in FIG4 . 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 .

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 member 2, and then align the avoidance holes 21 on the fitting member 2 with the position of the user's nostrils, so that the fitting member 2 is attached to the outer edge of the nostrils and fixed to the cheeks on both sides of the nose, and try to avoid bubbles. It can be seen that when in use, the fitting member 2 covers the outer edge of the nostrils and part of the cheeks to provide sealing support.

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.

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

The magnetic face-fitting nasal pillow provided by the utility model is a connection interface between a non-invasive positive pressure ventilation device and a user. The avoidance holes on the fitting component are aligned with the position of the user's nostrils, and the fitting component is attached to the outer edge of the user's nostrils and the cheeks on both sides of the nose to achieve sealing and better fixation. The nasal pillow support component is adsorbed onto the fitting component through the magnetic attraction force between the first magnetic attraction ring and the second magnetic attraction ring to provide a breathing gas channel. The utility model adopts the fitting component to replace the traditional headband, which can effectively get rid of the constraints brought by the traditional headband, and the manufacturing cost of the fitting component is lower. After the user tears off the fitting component, there is no indentation on the face, which does not affect the appearance; in addition, the fitting component is disposable and needs to be replaced with a new one after use by the user, and the setting of the fitting component makes it so that the nasal pillow support component 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, 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 suction, 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. Therefore, the magnetic face-fitting nasal pillow provided by the utility model 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 users with a breathing passage safely and comfortably.

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.
