Silicone LMA Laryngeal Mask Airway Double Cavity Type For General Anesthesia Surgery

The laryngeal mask is used for general anesthesia surgery, and the breathing channel to ensure the patient's breathing. The laryngeal mask can close the laryngopharyngeal cavity and the laryngeal cavity. There is a breathing channel in the center of the laryngeal mask that directly communicates with the larynx cavity, and the distal end is connected to a ventilator to maintain the patient's breathing. The laryngeal mask is not inserted into the trachea through the larynx like the tracheal intubation. It can avoid damage to the larynx cavity, cause dislocation of the ring-dipper joint, and avoid damage to the tracheal mucosa. It is suitable for general anesthesia operations other than upper respiratory tract surgery.
