Abstract
A saliva collector comprises a reservoir and a flow path from an inlet to an outlet on the reservoir. Air aspirated from the patient's oral cavity passes through an antechamber before reaching the reservoir. The antechamber is shaped to promote the collapse of any bubbles, allowing liquid saliva to drop from the antechamber to the reservoir.
