Abstract
A saliva collector comprises a reservoir and a flow path from an inlet to an outlet on the reservoir. A heating element is disposed along the flow path. The heating element applies heat to force bubbles and foam present in the air aspirated from a patient's oral cavity to collapse. The collapsed bubbles and foam evaporate or drain into the reservoir bottom as liquid saliva.
