Innovators in Nasal Intubation

To increase the safety and ease of nasal intubations, Rhinoguard is designed to provide significant improvements over existing off-label devices used by the anesthesia community.

The Rhinoguard incorporates the dilating ability of multiple nasal trumpets and a protective sheath, like a red rubber catheter. Unlike the use of multiple nasal trumpets manipulated in and out of the nasal cavity, the Rhinoguard is moved in only one direction. Utilizing multiple nasal trumpets has been known to result in nasal bleeds, as well as a prolonged intubation process. Red rubber catheters used for nasal intubations can, at times, separate prematurely from the endotracheal tube and can be difficult to disconnect. Also, the stretching and snap of a red rubber catheter when disconnected from an endotracheal tube is a biohazard. This issue does not exist with the Rhinoguard. Red rubber catheters are known to spool up and become lost in the nasopharyngeal anatomy. With the Rhinogaurd, even when it is mated to a 3.0 endotracheal tube, in an average 16-year-old, its proximal end remains visible outside of the nares, its distal end is visible in the oropharynx and it cannot be lost.

The Rhinoguard's multiple endotracheal tube size options provide a customized fit, not available with a red rubber catheter. The red rubber catheter also lacks stiffness, making it difficult for the catheter to pass through more tortuous nasopharyngeal anatomy. The Rhinoguard, in its long axis, provides a relative stiffness somewhere between that of a red rubber catheter and that of an endotracheal tube, making it easier to pass through a more narrow nasal passage and providing greater ability to utilize a larger diameter endotracheal tube for greater length and ease of intubation. The small Rhinoguard will never buckle and the large Rhinoguard will only buckle when forced past a 90ยบ angle, ensuring it can always be advanced if there is a viable pathway.

The Rhinoguard also allows the user to determine if there is a viable pathway to safely pass through either naris without causing a brisk bleed. A red rubber catheter may provide a false read that you cannot navigate the anatomy and an endotracheal tube alone may tunnel or lacerate hard and/or soft tissue before knowing that a nasal approach is not an option.

The Rhinoguard is the first and only FDA cleared device to aid in nasal intubations. We believe the Rhinoguard combines all the properties of off-label devices into one advantageously designed, for use device.
