    摘要： A specimen collection container having a separation chamber includes a first chamber, a second chamber, and a valve located between the first chamber and the second chamber. In an open position, the valve permits fluid communication between the first chamber and the second chamber. In a closed position, the valve maintains fluid isolation between the first chamber and the second chamber. A fluid stream passes from the first chamber to the second chamber through the valve permitting a predetermined volume of fluid to pass from the first chamber to the second chamber. When the predetermined volume of fluid passes to the second chamber, the valve transitions from the open position to the closed position so that additional fluid of the fluid stream received by the first chamber is maintained in the first chamber in fluid isolation from the predetermined volume of fluid contained in the second chamber.

    摘要： A needle assembly includes a transparent or translucent housing with a fluid inlet and outlet end, a flashback chamber, and a venting mechanism therebetween. The venting mechanism includes a blocking member to control the fluid flow in the venting mechanism so that it flows along the longest path through the vent. Substantially axially aligned inlet and outlet cannulas extend from the housing and communicate with the chamber. A sealable sleeve covers the external end of the outlet cannula. Relative volumes of the cannulas, the chamber, and the sleeve are selected to provide rapid reliable flashback indicative of venous entry with an internal vent positioned within the housing to divide the interior into first and second chambers, with the second chamber being adapted to maintain a negative pressure therein relative to the external environment so as to inhibit leakage of blood from the needle tip on withdrawal from the patient.

    摘要： A retractable needle assembly includes a housing having a sidewall defining a hollow bore, and an elongate plunger, the distal end of the plunger forming a reservoir within the hollow bore for containing a fluid therein. The plunger is adapted for slideable movement within the hollow bore. The assembly includes a hub disposed within the hollow bore and at least partially supporting a cannula therewith, and a needle retraction member engaged with the hub for manually selectable advancement with respect to a portion of the housing. The needle retraction member may be advanced from an initial position in which at least a portion of the needle is disposed outside the housing, to a retracted position in which the needle is fully surrounded by the housing. The elongate plunger may be advanced about the hub for extracting the fluid into the reservoir or expelling the fluid from the reservoir.

    摘要： A biological fluid collection device that is adapted to receive a blood sample having a cellular portion and a plasma portion is disclosed. After collection of the blood sample, the plasma portion is separated from the cellular portion. After separation, the biological fluid collection device is able to transfer the plasma portion of the blood sample to a point-of-care testing device. The biological fluid collection device also provides a closed sampling and transfer system that reduces the exposure of a blood sample and provides fast mixing of a blood sample with a sample stabilizer. The biological fluid collection device is engageable with a biological fluid testing device for closed transfer of a portion of the plasma portion from the biological fluid collection device to the biological fluid testing device. The biological fluid testing device is adapted to receive the plasma portion to analyze the blood sample.

    摘要： A container assembly for collecting a fluid specimen including a collection container having a first end, a second end, and a sidewall extending therebetween and defining a chamber for receiving the fluid specimen. The container assembly may include a container lid couplable to the collection container to at least partially close the first end thereof. The container lid may include a sealing interface configured to at least partially contact the collection container when the container lid is coupled to the collection container. The sealing interface may include a textured sealing surface region configured to allow air into or out of the container assembly when the container lid is coupled to the collection container, while maintaining a substantially fluid-tight seal between the container lid and the collection container.
