Abstract
A saliva collector comprises a reservoir, a bubble barrier, and a membrane, where the bubble barrier and membrane are arranged in tandem on a flow path from an inlet to an outlet on the reservoir. Air aspirated from a patient's oral cavity enters the reservoir through the inlet, passes through the bubble barrier to remove foam and bubbles, passes through the membrane to remove entrained liquid saliva, and passes out through the outlet.
