The Tongue Sucker is a small plastic chamber with abulb-shaped air reservoir which allows untrained bystanders at thescene of an emergency to keep the airway of an unconscious person open.
You squeeze the bulb, place it over the tongue of the injured person and release.
Suction then draws the tongue off the back of thethroat, creating a small but vital gap to allow the unconscious personto breathe.
Once in place, the first-aider is free to perform CPR(cardiopulmonary resuscitation), call for help or assist othercasualties. In addition, the brightly coloured bulb signals to arrivingparamedics which casualties have been treated.
