In addition, the terms "first", "second", "third" and the like are only for the purpose of description, and cannot be understood as indicative or suggestive of relative importance.

[0024] In the description of the utility model, it also needs to explain that, unless otherwise specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected;It can be mechanically connected, or it can be electrically connected;It can be directly connected, or it can be indirectly connected through an intermediate medium. For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0025] Referring to Figures 1-3 , the structure diagram of the ear-hung nasal oxygen tube provided by the application comprises an oxygen inhalation tube 1 and a nasal plug 2, the nasal plug 2 is connected with an oxygen inhalation tube 1 on each side, in the embodiment, the nasal plug 2 is a double-nose nasal plug, which can supply oxygen to two nasal cavities at the same time, and the wearing mode is the same as that of the existing ear-hung nasal oxygen tube, and the innovation of the application mainly lies in the soft pad 3 and the mandibular fixing mode.

[0026] Among them, the part of the oxygen inhalation tube 1 contacting the ear is provided with a soft pad 3, the soft pad 3 is of a sleeve type structure and is wrapped on the oxygen inhalation tube 1 by adhesion. The soft pad 3 is made of foam sponge material, which not only plays a role of anti-skid, but also is very soft, improving the comfort.

[0027] And, as Figure 3 shown, the soft pad 3 is provided with a metal wire 4 extending in the same direction as the oxygen inhalation tube 1, the metal wire 4 is symmetrically arranged in two, in the case of ensuring sufficient support, the metal wire 4 is also avoided to cause pressure on the ear due to too much. The metal wire 4 is an iron wire or an aluminum wire, which is low in cost and easy to manufacture. In use, the plasticity of the metal wire 4 is utilized to change the shape of the oxygen inhalation tube 1, so that it is bent into a shape structure fitting the ear, which is similar to the nose bridge pressing strip on the mask, thereby reducing the pressure on the ear caused by long-term wearing of the nasal oxygen tube and reducing the probability of pressure ulcer of the ear.

[0028] As Figure 2As shown, the present application is provided with the buckle type fixing mechanism matched with each other at the part contacting with the lower jaw on the two oxygen inhalation tubes 1, and the traditional sliding fixing ring is not fixed firmly when fixing the lower jaw, which causes the oxygen inhalation tube to be loose and slip off, resulting in the poor oxygen therapy effect of the patient with continuous nasal catheter oxygen inhalation, and affecting the treatment effect. The buckle type fixing mechanism includes a plurality of male buckles 5 and female buckles 6 vertically arranged on the two oxygen inhalation tubes 1 respectively, the oxygen inhalation tube 1 is fixed at the lower jaw by the buckle connection of the male buckle 5 and the female buckle 6, the appropriate buckle position is selected according to the tightness when the patient wears, and the fixing ring is fixed at the lower jaw by the segmented buckle type fixing, so that the uncontrollable factors of tightness caused by the fixing ring when the patient moves are reduced.

[0029] When wearing, the nasal plug 2 is first put into the nasal cavity of the patient, then the oxygen inhalation tube 1 is wound behind the ear, the soft pad 3 is adhered to the ear, the metal wire 4 in the soft pad 3 is used to bend the soft pad 3 to the shape structure adhered to the ear, the pressure caused by the long-term wearing of the nasal oxygen tube on the ear is reduced, then the tail of the two oxygen inhalation tubes 1 is buckled and connected by the male buckle 5 and the female buckle 6 at the lower jaw of the patient, and the appropriate buckle position is selected to prevent the oxygen inhalation tube from being loose and slipping off.

[0030] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited to this, any skilled person in the technical field can easily think of the changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
