A curved tube used in inhalational anaesthesia and resuscitation to facilitate and secure airway patency for the delivery and exchange of gases in spontaneously breathing and ventilated patients. It is inserted into the pharyngeal cavity to prevent the tongue from obstructing the anatomical airway. It may include a 15 mm connector that attaches to a breathing circuit or manual resuscitator, be radiopaque, and have a distal inflatable cuff to seal against the tracheal wall and have a built-in pilot balloon for cuff pressure monitoring. It is available in various sizes/designs and is typically made of silicone/plastic materials. This is a reusable device.
