Detailed Description

The following detailed description of embodiments of the utility model refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

In the present invention, the terms of orientation such as "up and down" are used to indicate the orientation in which the wearer is in a standing wearing state, unless otherwise specified. "inner and outer" refer to the inner and outer contours of the respective component itself.

The utility model provides a nasal oxygen tube structure, wherein the nasal oxygen tube structure 10 comprises a main body 11 with lateral wings 111 at two lateral sides respectively and two nasal plugs 12 arranged in the middle of the main body 11, the main body 11 is provided with an air channel 112 communicated with the nasal plugs 12, the air channel 112 can be communicated with an air source, and the two lateral wings 111 are respectively provided with bonding pieces capable of being bonded with the face of a wearer.

In the above, it will be appreciated that the nasal prong 12 is tubular for insertion into the nasal cavity of the wearer. In use, gas from the gas source may enter the gas passage 112 and then pass through the gas passage 112 into the two nasal prongs 12, ultimately passing the gas into the airways of the wearer.

The nasal oxygen tube structure 10 of the present invention is provided with the side wings 111 on both lateral sides of the main body 11, and the side wings 111 are provided with the adhesive member capable of adhering to the face of the wearer, so that the nasal oxygen tube structure 10 can be reliably fixed to the face of the wearer by the adhesive member when worn, and does not need to be fixed by a headband, and the nasal oxygen tube structure is flexible and easy to wear, has a high wearing comfort, and is particularly suitable for infants.

In the above, the wings 111 are provided at both lateral sides of the main body 11, and the wings 111 may have a large area to maintain a large bonding area with the face of the wearer while making the middle portion of the main body 11 small in size, thereby ensuring the wearing reliability while making the main body 11 small in size (see fig. 5 to 9). Wherein, for example, as shown in fig. 5-9, the shape of the side wing 111 can be rectangular, conical, drop-shaped, polygonal, etc., and the side wing 111 has a larger area, which can range from 5 cm to 20cm²)。

In the present invention, the main body 11 and the nasal plug 12 are preferably made of soft materials such as silica gel and TPE, and the hardness ranges from 30 degrees to 60 degrees.

In the present invention, referring to fig. 4, the nasal prongs 12 may extend upward and toward the face of the wearer to conform to the shape of the nasal cavity, the length of the nasal prongs 12 is preferably 5-12mm, the wearer may feel pain if the nasal prongs 12 are too long, and the efficiency may be affected if the nasal prongs 12 are too short, which may cause the air to escape during the air supply. In addition, referring to fig. 3, the two prongs 12 may extend obliquely towards each other to accommodate the nasal cavity shape, preferably at an angle of 15-25 °.

The adhesive member may be implemented in various ways, such as a double-sided adhesive layer 13 adhered to the inner side of the side flap 111 (i.e. the side close to the face of the wearer) (the double-sided adhesive layer 13 may have a certain redundancy, such as an additional 20% -50%, relative to the side flap 111). That is, the double-sided adhesive layer 13 is not only fixed to the wearer's face by adhesion, but also fixed to the side flap 111 by adhesion (in this case, the inner side surface of the side flap 111 is formed as an adhesive surface). It is also conceivable that the adhesive may be a single-sided adhesive layer, i.e. secured to the wearer's face only by gluing, and to the side flap 111 by other securing means.

In the case of the adhesive member being a double-sided adhesive layer 13, the double-sided adhesive layer 13 may be a double-sided adhesive film, one side of which is adhered to the side wing 111 and the other side of which is adhered to the face of the wearer. The side glue adhered to the side wing 111 can be made of different glue materials according to the material change of the side wing 111, for example, the side wing 111 is made of a silica gel adhesive, and the side wing 111 is made of a TPE adhesive; the side adhesive adhered to the face of the wearer can be made of a certain silica gel adhesive material which is not damaged when the side adhesive is adhered to the face, and 2458 silica gel adhesive is preferred. In addition, the carrier for carrying the two side adhesive layers, which is located in the middle layer of the double-sided adhesive layer 13, is preferably a mesh-type non-woven fabric, so that the air permeability of the double-sided adhesive layer can be ensured due to long-term adhesion to the face. The double-sided adhesive layer 13 can be repeatedly adhered for a plurality of times so as to be adjusted and adhered after being detached when the wearing position is not reasonable. The side of the double-sided adhesive layer 13 for adhering to the face of the wearer may be adhered with a release paper 14 to ensure that the side for adhering to the face of the wearer before use is not contaminated, and the release paper 14 may be torn off when needed (see fig. 10-11, 16).

In the present invention, the air passage 112 may have various embodiments, and may be one passage communicating with two nasal plugs 12 at the same time, or may be two passages communicating with two nasal plugs 12 respectively (see fig. 5). In the case of a channel, which may be arranged to extend from one side wing 111 to the other side wing 111, the two prongs 12 each extend upwardly from the middle of the channel. In the case of two channels, the two channels may be located on the two side wings 111, respectively, as shown in fig. 5, and the portion between the two channels is blocked, that is, the middle portion of one channel extending from one side wing 111 to the other side wing 111 may be provided as a solid.

In the present invention, the nasal oxygen tube structure 10 may further include a connection tube 15, and the connection tube 15 is in communication with the gas passage 112. The connecting tube 15 may pass gas from a gas source into the gas passage 112.

The gas passage 112 may be single-side or double-side. In the case of the double-side gas inlet, both ends of the gas passage 112 are formed as two connection ports 113 (see fig. 5), and the nasal oxygen tube structure 10 includes two connection tubes 15 (see fig. 12) connected to the two connection ports 113, respectively. In the case of the single-side intake, the gas passage 112 has only one connection port 113, and the nasal oxygen tube structure 10 includes one connection tube 15 connected to one connection port 113.

In the case of having two connection pipes 15, as shown in fig. 1 and 13, the nasal oxygen tube structure 10 may include a slider 16, the slider 16 is provided with two parallel through holes, the two connection pipes 15 are respectively inserted into the two through holes, and the slider 16 can slide along the two connection pipes 15. The slider 16 can combine the two connection pipes 15 together, and the two connection pipes 15 can be folded when being worn according to the size of the head of a wearer by adjusting the slider 16, so that the possibility that the two connection pipes 15 are dragged and the like due to scattering or disorder of the two connection pipes 15 is reduced. In other embodiments, a clip may be used to directly snap into place at a desired location.

In the utility model, the connecting pipe 15 can be a pipeline which has certain softness and is not easy to bend, the material of the connecting pipe can be silica gel, PVC and the like, and the wall thickness range can be 0.5-2 mm.
