Patent ID: 8025851

Claim:
A specimen sample collection device and test system, comprising: a handle including a sufficiency indicator and means for providing a water tight seal between said handle and a pad compression tube insertable over said handle; an absorbent pad partially contained within said handle, said absorbent pad comprising round cylindrical shape; a pad compression tube insertable over said absorbent pad within said handle and around an end of said handle, said pad compression tube including one or more outlet ports; and, one or more collection tubes having one or more sample chambers, attachable to said one or more pad compression tube outlet ports, and wherein said compression tube defines one or more chambers in fluid communication with said one or more pad compression tube outlet ports, and wherein when said collection tube is attached to said one or more pad compression tube outlet ports, the chambers are in fluid communication with said pad compression tube; wherein said sufficiency indicator is a wrap-around light pipe of substantially annular shape and a portion of said absorbent pad extends into the annulus of said wrap-around light pipe, said light pipe including a first end surface with a marking and a second surface in physical contact with said absorbent pad creating a refractive boundary, said second surface oriented at an angle of incidence to said first surface such that when the absorbent pad absorbs a sufficient liquid sample the refractive properties of said boundary alter the observability of the mark.
