Oral fluids collection device and method

An oral fluids collection kit comprising:

• (a) a durable component comprising:
• (i) a shield having a first face and a second face;
• and
• (ii) an elastomeric nipple having an outer surface and defining a nipple interior extending from the first face of the shield;
• and
• (b) a plurality of attachable reservoir components arranged and configured for demountable engagement to the shield, each attachable reservoir component comprising a reservoir having a reservoir interior;
• wherein an assembly of one of the plurality of attachable reservoir components to the durable component defines an oral fluids collection device having (1) a first fluid conduit having a first one-way valve operatively connecting and permitting flow from the nipple interior to an atmospheric vent port disposed on an exterior surface of the oral fluids collection device;
• (2) a second fluid conduit having a second one-way valve operatively connecting and permitting flow from the reservoir interior to the nipple interior;
• and (3) a third fluid conduit having a third one-way valve operatively connecting and permitting flow from a collection port disposed on the outer surface of the nipple to the reservoir interior.
