Description

Technical Field

[0001] The utility model relates to the technical field related to medical devices, in particular to a nasopharyngeal airway. Background Art

[0002] Nasopharyngeal airways are used in medical devices, and are particularly suitable for patients with tight mandibles, trismus, oropharyngeal surgery, and difficulty in inserting an oral airway. Compared with oropharyngeal airways, nasopharyngeal airways are simple to insert and can be operated with a little training. The operation can be completed in a short time to achieve effective ventilation. The biggest feature and advantage of nasopharyngeal airways is that they are simple to operate, easy to use, and effective. They can be mastered with a little training, and can be effectively ventilated within a few seconds or in an instant. Nasopharyngeal airways have a wide range of applications. They are currently mainly used in anesthesiology, respiratory medicine, etc. to help patients to clear their airways, thereby facilitating medical operations.

[0003] At present, the polyethylene material used for the nasopharyngeal airway during medical device surgery is too sensitive to smell, affecting the patient's nasopharyngeal ventilation and breathing. The nasopharyngeal airway material is too soft and difficult to install. The nasopharyngeal airway is easy to fall off, making medical surgery difficult. The nasopharyngeal airway is easily blocked during the patient's breathing. Utility Model Content

[0004] The purpose of the utility model is to provide a nasopharyngeal airway to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A nasopharyngeal airway comprises a silicone tube and a respiratory airway movably mounted on the silicone tube, wherein the respiratory airway is provided with a nasopharyngeal ventilation silicone tube on the outside, and silicone plugs are fixedly connected to both sides of the nasopharyngeal ventilation silicone tube.

[0007] An anti-smell component, mounted on the silicone tube;

[0008] A built-in ventilation component is arranged on the nasopharyngeal ventilation silicone tube and is connected to the anti-pungent component to ventilate the anti-pungent component in the tube for nasopharyngeal ventilation delivery;

[0009] An anti-falling component is installed on the silicone plug. A nasopharyngeal silicone plate is provided at the connection of the silicone plug to prevent the built-in ventilation component from falling off. When the anti-falling component is in use, the anti-falling component remains in a supported state.

[0010] The nasopharyngeal airway as described above: the anti-pungent component includes a silicone airway fixedly installed on the rear end of the nasopharyngeal ventilation silicone tube, and a silicone airway tube is fixedly connected to the silicone airway tube mouth to provide a plugging space for nasopharyngeal ventilation connection to the built-in ventilation component.

[0011] The nasopharyngeal airway as described above: the built-in ventilation component includes a circular groove fixedly connected to the respiratory airway, the circular groove fits and is embedded in the nasopharyngeal ventilation silicone tube, and a respiratory ventilation hole is opened at the front end of the respiratory airway.

[0012] The nasopharyngeal airway as described above: the respiratory airway is connected to the respiratory vent hole inside the nasopharyngeal ventilation silicone tube.

[0013] The nasopharyngeal airway as described above: the respiratory airway is sleeved on the front end of the silicone airway, and the silicone airway is threadedly connected to the nasopharyngeal ventilation silicone tube for isolating the inside of the anti-fall-off component for ventilation.

[0014] The nasopharyngeal airway as described above: the anti-falling component includes an internal spring net movably installed in the silicone plug, and the silicone plug is fixed to a silicone block on the internal spring net.

[0015] The nasopharyngeal airway as described above: the internal spring net and the silicone block are fixedly connected, and the internal spring net and the silicone block are plugged in the nasopharynx by a silicone plug to prevent them from falling off.

[0016] Compared with the prior art, the utility model has the following beneficial effects: the respiratory airway is elastically embedded in the inner side of the nasopharyngeal ventilation silicone tube through the circular groove. After the nasopharyngeal airway is normally inserted, the patient breathes and exhausts normally through the respiratory airway and the respiratory vent. When the silicone tube and the nasopharyngeal ventilation silicone tube are blocked, the medical staff can also elastically squeeze and remove the respiratory airway to avoid respiratory blockage in the patient. The nasopharyngeal silicone patch and the silicone plug are deformed and reduced under stress. After the nasopharyngeal silicone patch and the silicone plug are installed in the nasopharyngeal airway, the nasopharyngeal silicone patch and the silicone plug that are deformed and reduced under stress can be unfolded and elastically stuck in the nostrils. The silicone tube and the nasopharyngeal ventilation silicone tube on the inner side of the nasopharyngeal silicone patch and the silicone plug are placed in the nostrils through the nasopharyngeal silicone patch, which has an anti-falling effect. The nasopharyngeal silicone patch and the silicone plug will not cause pain and discomfort to the patient due to their own materials. BRIEF DESCRIPTION OF THE DRAWINGS

When the nasopharyngeal ventilation silicone tube 2 is installed for the nasopharyngeal airway, the silicone plug 3 is plugged on both sides of the nasopharyngeal ventilation through the nasopharyngeal silicone patch 4. The silicone tube 1, the nasopharyngeal ventilation silicone tube 2 and the nasopharyngeal silicone patch 4 are made of silicone material to avoid pungent odor. At the same time, the silicone plug 3, the silicone tube 1, and the nasopharyngeal ventilation silicone tube 2 are soft enough to prevent nasopharyngeal solution infection.

The respiratory airway 5 is elastically embedded in the inner side of the nasopharyngeal ventilation silicone tube 2 through the circular groove 9.

At the same time, the silicone block 11 is fixedly connected to the built-in spring net 10 for elastic extrusion.

[0037] Preferably, the built-in spring net 10 and the silicone block 11 are fixedly connected, and the built-in spring net 10 and the silicone block 11 are plugged in the nasopharynx through the silicone plug 3 to prevent the silicone block 11 from falling off.
