US 8,025,851 B2 · Specimen sample collection device and test system

Abstract

A specimen sample collection device and test system includes a handle with a sufficiency indicator and locking teeth, an absorbent pad partially contained within the handle; a pad compression tube with outlet ports and locking holes insertable over the pad and handle; one or more collection tubes attachable to the pad compression tube outlet ports. The apparatus may include a light pipe sufficiency indicator with a spring compressor to force the absorbent pad into contact with the light pipe. The apparatus may include a collector dam. The apparatus may include a secondary seal. The apparatus may include a cylindrically shaped absorbent pad and a wrap-around light pipe sufficiency indicator with vent grooves. The apparatus may include a pad seat with buffer material disposed within the pad compression tube. The apparatus may include an absorbent pad split and divided into two lengths connected at a base. The apparatus may include a bar code identification. The apparatus may include a lock and key securing mechanism. The apparatus may include a handle containing one or more analyte test strips The apparatus may include a first absorbent pad in fluid communication with a sample adequacy indicator, which is in parallel with a second absorbent pad in fluid communication with a lateral flow analyte test strip. The apparatus ma include a first absorbent pad in fluid communication with a sample adequacy indicator, which is in parallel with a second absorbent pad in fluid communication with a lateral flow analyte test strip, with an impermeable membrane separating the first and second absorbent pads.

Dependent claims

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.
