Claims25
An oral fluid collection device comprising:
- a handle;
- a swab holder;
- a swab in the form of a hollow tube of absorbent material coaxially located about the swab holder, such that the swab is supported by the swab holder along the entire length of the swab;
- and
- a wick within the swab holder and being in fluid communication with the swab, the wick containing a soluble dye for the purpose of providing a fluid adequacy indication during use;
- wherein the swab holder has an at least partially hollow core accommodating said wick, an opening passing through a wall of the swab holder into the hollow core, and a projection on an inner surface of the hollow core opposite the opening and which tends to press the wick through the opening and into contact with the swab.
