Abstract:
1. An extraction wand for use in a device for testing a drug of abuse or other analyte from a body fluid sample collected from a person being tested for said drug or analyte comprising: a handle having a hollow internal cavity having at least one latching means internally positioned for retaining a stem constructed to fit slidably into said cavity so that said handle will be downwardly slidable over said stem, and an external configuration at its distal end that can apply compression to a sponge positioned upon said stem; a stem constructed to fit into said internal handle cavity and having at least one protrusion on its external surface so that the latching means internally positioned in the cavity will retain the handle in a locked position when said handle is brought downward over the stem, said stem further having a means at its distal end for retaining a sponge; and a sponge disposed at the distal end of said stem which is capable of absorbing a body fluid from the person to be tested for the presence of a drug or other analyte, and which is positioned on the stem so that the body fluid sample will be expressed from the sponge when the handle is brought downward over the stem and impinges upon said sponge.
