MULTI-STAGE ORAL-FLUID TESTING DEVICE

摘要

In an embodiment, the claimed invention includes an oral-fluid collection and testing device that. is simple to operate. The device includes a body assembly and a cap assembly that are easy to handle by a user. A collection sponge projects from an end of the body assembly for absorbing the oral fluid of a donor, A cap assembly is easily aligned with the body assembly by way of visual alignment indicators on both the body and the cap. Once the cap is aligned with the body, a user simply pushes the cap onto the 'body, which causes a first stage fluid, flow. More specifically, a buffer fluid is released from the cap and mixes with the oral fluid collected on the sponge—After waiting a short time* the cap is rotated, then pushed again, causing a second-stage fluid flow in which the sponge is compressed such that the buffer fluid/oral fluid exits the sponge and flows toward a. pair of test strips. A user can then easily view the test results by observing a visual indication, such as a color change of the test strips through a viewing window.

主权项

1. A multi-stage, oral-fluid collection and testing device for collecting and testing an oral-fluid for substances, the testing device comprising:
a body assembly, including:
a collection sponge for absorbing an oral fluid received from a donor,a test strip for receiving the oral fluid and presenting a visual indicator indicating presence of a predetermined substance,a body portion securing the collection sponge and the test strip and defining a fluid reservoir and a test strip channel, the test strip located in the test strip channel; and a cap assembly, including:
a cap having a first closed end and a second open end, and configured to receive a portion of the body assembly, the cap defining a cap cavity;a fluid container having a sealing membrane and containing a fluid for mixing with the oral fluid, the fluid container housed within the cap cavity, anda plunger defining a fluid channel; wherein the cap assembly is configured to release the fluid for mixing onto the collection sponge upon receiving a cap-engagement portion of the body portion in a first engagement position, thereby causing a first-stage fluid flow.
