Multi-stage oral-fluid testing device

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.

Wound irrigation splashback shield

A splashback shield for attachment to a syringe for wound irrigation includes a generally dome-shaped shield with a conduit or tunnel through the top that narrows to form a nozzle as it extends substantially inside the shield. A number of air vents or passageways surround the conduit so when submerging and re-filling the syringe with irrigant with the shield attached any air trapped inside the shield escapes rather than drawn into the syringe. The air vents are preferably elongate tubular passageways that narrow exiting the shield, facilitating air escaping but the irrigant mixed with any blood and contamination tends not to pass through the vents. The device is an improvement over the conventional Zerowet® Splashield® product.
