[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0018] Referring to Figure 1 , Figure 2 and Figure 3 , one embodiment provided by the utility model is as follows: a nasopharyngeal airway for one-time use, comprising an air passage body 1, a first air inlet 2 is arranged at the left end of the air passage body 1, a second air inlet 3 is arranged at the right end of the air passage body 1, and a soft rubber block 4 is arranged on the outer wall of the left end of the air passage body 1.

[0019] Further, the airway body 1 is provided with the first air port 2, one end of which is inserted into the patient's nasal cavity and extends to the patient's trachea, and the second air port 3, one end of which is outside the nasal cavity, and the first air port 2 and the second air port 3 are communicated, so that the patient can achieve the effect of unobstructed breathing. When the end provided with the first air port 2 is inserted into the patient's nasal cavity, a soft rubber block 4 is arranged at one end of the first air port 2. The soft rubber block 4 can reduce the pressure and friction of the airway body 1 on the nasal cavity, improve the fit of the airway body 1 and the nasal cavity wall, and reduce the discomfort of the patient.

[0020] Referring to Figure 1 and Figure 3 The outer wall of the airway body 1 is sleeved with a fixed ring 5, the left and right ends of the outer wall of the fixed ring 5 are fixedly connected with soft pads 6, the front end of the outer wall of the fixed ring 5 is fixedly connected with a connecting rod 7, one end of the connecting rod 7 away from the fixed ring 5 is fixedly connected with a connecting block 8, the connecting rod 7 is arc-shaped, and the four corners of the connecting rod 7 are rounded.

[0021] Further, the fixed ring 5 can be moved on the airway body 1, the fixed ring 5 is arranged at the patient's nasal orifice, the two sides of the fixed ring 5 are provided with soft pads 6, the soft pads 6 contact the skin of the patient's nasal orifice, and the comfort of the patient can be increased, and the connecting rod 7 is arc-shaped, so that the connecting rod 7 can be more fitted to the patient's alae nasi.

[0022] Working principle: The nasopharyngeal airway is suitable for patients who are recovering from general anesthesia or coma, and patients with upper respiratory tract obstruction caused by various reasons. The purpose is to maintain the unobstructed breathing of the patient. When using the nasopharyngeal airway, first, the outer wall of the airway body 1 needs to be smeared with paraffin oil or physiological saline to be moistened, then the airway body 1 and the patient's face are in a vertical direction, one end of the first air port 2 of the airway body 1 is gently inserted into the patient's nasal cavity and extends to the trachea. When inserting, if resistance is encountered, it cannot be forcibly inserted, the direction can be adjusted or inserted into the other nostril, then the fixed ring 5 on the airway body 1 is moved, so that the fixed ring 5 can be arranged at the patient's nasal orifice, the connecting rod 7 is made of elastic rubber material, the connecting rod 7 is pulled to be arranged outside the patient's nose, the connecting rod 7 cooperates with the airway body 1, so that the patient's alae nasi can be clamped between the airway body 1 and the connecting rod 7, the connecting block 8 is driven by the connecting rod 7 outside the patient's nose, the connecting block 8 is made of soft rubber material, so as to avoid pain when the patient's alae nasi is fixed, a soft rubber block 4 is arranged at one end of the first air port 2, which can reduce the pressure and friction of the airway body 1 on the nasal cavity, improve the fit of the airway body 1 and the nasal cavity wall, and reduce the discomfort of the patient. The nasopharyngeal airway is a disposable product, after use on the patient, it should be discarded in the corresponding medical waste collection garbage can, to achieve the effect of safety and health.

[0023] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
