Abstract: A biological fluid collection device with a pivotable faucet is disclosed. The device is designed to collect, hold and transfer a biological specimen into a non-evacuated tube through an integrated pivotable faucet component. This device uses no needles, either blunt or sharp, and provides safety from needle puncture. The device works with a non-evacuated tube and a specially designed cap that attaches to the container via the pivotable faucet. The device includes a container for collecting, holding and transferring the biological fluid. The design of the container facilitates use of the tube as a handle in order to position the container to receive collection of the biological fluids. The method of collection begins with using the non-evacuated tube as a handle to hold the container and collecting the biological specimen in the container. A lid is attached to the top of the container to prevent contamination and exposure to the specimen during transfer into the non-evacuated tube.

Abstract: A device and method is provided for separating heavier and lighter fractions of a fluid sample. The device includes a plurality of constituents. The constituents include a container, a liner in the container and a composite element in the liner for separating the fractions of a fluid sample. The separator comprises a specific density at a target density range as defined by separable fluid components densities. A fluid sample is delivered to the liner and then the device is subjected to centrifugation whereby the centrifugal load causes the liner to deform and the composite element migrates into the fluid sample and stabilizes between the heavier and lighter fractions of the fluid sample. The liner will resiliently return to its initial configuration upon termination of the centrifugal load such that the liner sealingly engages the composite element and separates the heavier and lighter fractions of the fluid sample.

Abstract: The present invention is a syringe tip cap comprising a bottom portion, a top portion, an annular skirt extending therebetween and a plug that projects proximally from the bottom portion so as to be telescoped into the passage of a syringe tip. The plug provides means to allow air to be vented from the syringe with contacting the user. The syringe tip cap of the present invention also provides the user with an indication by tactile and visual feedback that the syringe has been vented.

Abstract: A device and method for separating heavier and lighter fractions of a fluid sample. The device includes a flexible collapsible inner container disposed within a substantially rigid outer container. A closure seals the open top end of the outer container. A filter assembly is sealingly mounted to the open top end of the inner container. The filter assembly includes a filter that permits lighter fractions to pass therethrough, while substantially blocking the heavier fractions. The filter assembly further includes a filter support having a slit valve registered with the filter. The slit valve opens in response to fluid pressure created by the lighter fractions for permitting the lighter fractions to flow therethrough.
