A laryngeal mask airway is provided. The laryngeal mask airway mainly includes a handle. A front end of the handle is connected to a mask body, and the handle and the mask body are formed of a flexible polymer material (e.g., polyvinyl chloride, PVC) for medical use. A guiding hole is formed at a side where the mask body and the handle are connected, and a working area is formed at an external opening of the guiding hole. With the working area, after an endotracheal intubation procedure is completed, a medical staff is able to hold the endotracheal tube with fingers throughout the whole procedure when the laryngeal mask airway is being removed, to prevent an improper movement of the endotracheal tube. |

1. A laryngeal mask airway, comprising:
a handle, wherein a front end of the handle is connected to a mask body, the handle and the mask body are formed of a flexible polymer material for medical use, wherein the flexible polymer material for medical use includes polyvinyl chloride (PVC); a guiding hole, formed at a side where the mask body and the handle are connected; and a guiding trench, formed on an exterior wall of the handle, and the guiding trench is in communication with the guiding hole, wherein when an endotracheal intubation procedure is completed by using the guiding hole and the laryngeal mask airway is to be removed, a medical staff holds an endotracheal tube with fingers by using the guiding trench and holds the handle with the other hand to slowly remove the laryngeal mask airway, removing of the laryngeal mask airway is paused when the mask body leaves a patient's larynx and touches the fingers holding the endotracheal tube, and as the mask body is already in a distance from the patient's larynx, a position where the endotracheal tube is held is moved to a position between the mask body and the patient's larynx, so as to resume to remove the laryngeal mask airway after holding the endotracheal tube again, such that an improper movement of the endotracheal tube caused when removing the laryngeal mask airway is prevented. |
