[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 As shown, the utility model provides a disposable anti-falling nasal oxygen cannula, including a nasal oxygen cannula 10, on which a nasal plug 20 that is interconnected is fixedly arranged, and on which a reinforcing plug 30 is fixedly arranged. After the reinforcing plug 30 is contracted by an external force with the nasal plug 20 as the center, it movably abuts against the nasal cavity and automatically fits to form a self-fixing structure. An anti-falling belt 40 is movably arranged on the nasal oxygen cannula 10, and after the anti-falling belt 40 slides along the outer wall of the nasal oxygen cannula 10 and is fixed around the ear to form a wearable structure.

[0025] The utility model adopts a double anti-slip form to form an adaptive anti-slip structure for the nasal oxygen tube. After the reinforcement plug is rubbed thin and the film is removed outside the film sleeve, it is inserted into the patient's nasal cavity through the nasal plug. The reinforcement plug rebounds and fills the patient's nasal cavity to form an adaptive anti-slip structure, and cooperates with the anti-slip belt to form a double reinforcement on the patient's ear. It can be adjusted and adapted according to the patient's use position and fixed range, greatly improving the stability of the nasal oxygen tube and making it not easy to fall off, reducing irritation to the skin, and helping to reduce the discomfort of the patient during use. It is suitable for patients at more stages for adjustment and use.

[0026] When in use, the reinforcement plug 30 is rolled into thin pieces and inserted into the patient's nasal cavity together with the nasal plug 20. After insertion, the reinforcement plug 30 adapts to the size and shape of the nasal cavity and rebounds, which is beneficial to improve the stability of the fixation of the nasal plug 20. At the same time, the anti-fall-off belt 40 is worn on the patient's ear for fixation, and adjusted to a more comfortable size according to the size of the ear, which can further enhance the wearing stability of the nasal oxygen tube 10 and reduce the situation where the nasal oxygen tube 10 is easy to fall off during use.

[0027] like Figure 1 and Figure 2 As shown, the outer wall of the reinforcing plug 30 is provided with grooves 31 at equal intervals, and the reinforcing plug 30 is integrally composed of an arc-shaped end 301 and a hollow cylindrical body 302.

[0028] By providing a groove 31 on the outside of the reinforcing plug 30, the reinforcing plug 30 can be prevented from completely fitting to the nasal cavity and causing excessive stickiness, which is convenient for removal after use without causing damage to the nasal cavity.

[0029] At the same time, the arc-shaped end 301 can reduce friction when the nasal plug 20 is inserted and adapt to the shape of the deeper part of the nasal cavity. The column body 302 near the nostrils reduces the expansion of the nostrils, which is conducive to enhancing the comfort of the patient when using it.

[0030] like Figure 2 and Figure 3 As shown, the reinforcing plug 30 is made of memory foam, and a film sleeve 32 is movably sleeved on the outer wall of the reinforcing plug 30 . One end of the film sleeve 32 surrounds the outer wall of the nasal oxygen tube 10 and forms a self-adhesive structure through an adhesive layer 321 .

[0031] The memory foam reinforcement plug 30 can be kneaded to become thinner and automatically rebound, and can fit the shape of the inside of the nasal cavity to make the nasal plug 20 fit more firmly and stably.

[0032] The film cover 32 can play an isolating role when the user rubs the reinforcement plug 30, which helps to keep the reinforcement plug 30 in a sterile state when entering the nasal cavity, and reduces the situation where bacteria remain on the surface of the reinforcement plug 30 and enter the nasal cavity to cause discomfort during operation. The film cover 32 can be directly torn off and removed during use, which is convenient for use.

[0033] like Figure 2 and Figure 3 As shown, the anti-slip belt 40 includes a fixing ring 41 movably sleeved on the outer wall of the nasal oxygen tube 10 , and a rubber ring 42 is slidably mounted on the outer wall of the anti-slip belt 40 .

[0034] The fixing ring 41 drives the anti-slip belt 40 to slide outside the nasal oxygen tube 10, so that it is easy to adjust to a suitable position for the patient to wear. The rubber ring 42 is helpful to adjust the wearing size and range of the anti-slip belt 40, so that it is convenient to adjust and use it according to different patients, reducing the situation of strangulation and falling off caused by the anti-slip belt 40 being too tight or too loose, which is conducive to improving the patient's comfort.

[0035] like Figure 2 and Figure 4 As shown, the rubber ring 42 is composed of a sleeve ring 421 and an open ring 422, and a ring piece 423 is slidably provided on the inner wall of the open ring 422. Magnets are provided on one side of the ring piece 423 and one side of the open ring 422. After the ring piece 423 rotates around the center position of the open ring 422 and closes, it is magnetically connected to the open ring 422 and encloses the anti-slip belt 40 inside.

[0036] The ring 421 is slid to a suitable position on the outside of the anti-slip belt 40 on one side to adjust the fixed size of the anti-slip belt 40, and then the open ring 422 is used to fix the anti-slip belt 40 on the other side so that the anti-slip belt 40 is fixed to the patient's ear, and the anti-slip belt 40 is inserted into the open ring 422, and then the ring piece 423 is rotated so that one side of the ring piece 423 is magnetically connected and fixed to one side of the open ring 422 through a magnet, and the anti-slip belt 40 is fixed inside, which is convenient for adjustment and use, and convenient for adjusting, fixing, putting on and taking off the anti-slip belt 40.

[0037] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
