BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an ophthalmic airway (OPA), and more particularly, to an artificial porcelain which can accurately secure a patient's airway.

The airway is a device for airway obstruction, preventing the occlusion of the upper limb in patients with unconscious or general anesthesia. Prayer is a type of nasopharyngeal airway (NPA) that is inserted into the nasal cavity of a patient with a conscious patient (such as a nasopharyngeal airway (NPA) ).

The stitches can be easily found in many patent documents such as U.S. Patent No. 7,278,420, U.S. Patent No. 7,866,313, U.S. Patent Application Publication No. US 2012/0048278 A1, PCT International Application No. WO 1999/029358 A1 . The furnace of this patent document has a passageway body and a flange formed at the proximal end of the passageway body. The passage body has a straight portion extending from the flange and a curved portion extending from the straight portion.

These utensils should be inserted so that the tongue does not cross the pharynx. The method of inserting pottery pottery is to put the tip of the curved part facing the palate into the palate and rotate it 180 degrees to put it into the mouth. The other way is to put it in the molar and rotate it 90 degrees. The contents disclosed in the above patent documents are incorporated herein by reference.

U.S. Patent No. 7,493,901 entitled " Laryngeal mask airway device "includes a backplate and a main-cuff at the end of an airway tube. The main cuff is a thin rubber bag that keeps the airtightness between the tube and the organs when inflated, preventing air from leaking to other parts of the esophagus and nose. Laryngeal mask airway has been used as an alternative to organ intubation in recent emergency patients and short operations.

As described above, the articulating pottery requires the surroundings because it may cause vomiting and pharyngospasm during insertion and push the tip of the tongue into the mouth. On the other hand, porcelain furnishings shall be of appropriate length. A long-length airway can push the epiglottis to completely close the airway. A shorter airway can push back the tongue. Therefore, it is required to have an oropharyngeal pacemaker that can prevent the tongue from falling to the pharynx during insertion.

On the other hand, tracheal intubation is the safest way to provide airway access to patients with various postures over a long period of time. US Patent No. 7,493,901 Flexible largoscopy is used to insert an intubation tube through the laryngeal mask airway or laryngeal airway. However, soft laryngoscopes are very expensive and difficult to move. In addition, the laryngeal airway is often used for tracheal and bronchial examination by the laryngeal muscles. However, when the bottom of the tongue comes down to the fins of the airway, The frequent isofficacy is low.
