ABSTRACT:
A breath-test mouthpiece of the type used to remove solids, saliva and water vapor from the breath of a subject being tested to determine a breath constituent, typically breath alcohol, including axially-aligned mouth and tube pipes with a hollow central collector having a lip-engaging edge to either side of the mouth pipe and an enlarged cross section multi-path interior baffle forcing the breath to flow along a serpentine-shaped path as it moves from the mouth pipe to the tube pipe.
