Abstract
An intra-oral device includes a tongue shield aspirator, a bite member, a bite grip, and an evacuation tube. The tongue shield aspirator may include a tongue retractor portion and a cheek retractor portion, and may be an open, unitary, and/or flexible component made of position-memory material. The bite member includes a conduit which receives the tongue shield aspirator through one end and the evacuation tube through the opposite end. The free end of the evacuation tube is connectable directly to a HVE valve to aspirate fluid/debris from the mouth. The device may be positioned in the mouth by bending the distal (free) end of the tongue shield aspirator, inserting the bite member into the mouth first, followed by the tongue shield aspirator as the device is moved towards the patient's cheek, releasing the free end of the tongue shield aspirator, and having the patient bite down on the bite member.
