Abstract
A selective collector of a human patient's saliva for monitoring or analysis is formed as a substantially conical flat concave cup of resilient molded polymer with tubing connections at an apex portal, and a large entrance portal having a soft compliant foam elastomer rim positioned for contact with the patient's soft tissue, such as the interior of the patient's cheek around the parotid salivary duct. Suction is connected to the soft foam rim, holding the concave cup in position, and suction, fixed pressure, pulsing pressure or electrical stimulation may promote the flow of saliva to a collector vessel. Medication may be administered to the patient's soft tissue if desired throug the entrance portal.
