Nasopharyngeal airway is designed for easy insertion and maximum patient comfort. It facilitates suctioning in intensive care, general anaesthesia and also provides an alternative airway during emergency procedures.
Slidable type/Thickened type/Trumpet type:
Slidable rings are designed to adjust depth of the tube for more comfort while also prevent tube from slipping into the nasal airway beyond the desired depth.
Thickened flange and trumpet flange are designed to prevent tube slipping into the nasal airway.
