The Tongue Sucker is a prototype device designed for forward displacement of the tongue from posterior pharynx, to open the airway during emergencies. The idea for the device has been conceived by four students at the Royal College of Art.

The Tongue Sucker's approach to the problem is simple and logical and may be performed by anyone.

The bulb is squeezed, the tube placed over the tongue, and released. This action creates a vacuum, which sucks onto the tip of the tongue pulling the rear off the throat and into the carefully designed self-sealing chamber.
