  • Publication number: 20140305197
    Abstract: A blood separation device that is adapted to receive a multi-component blood sample is disclosed. After collecting the blood sample, the blood separation device is able to separate a plasma portion from a cellular portion. After separation, the blood separation device is able to transfer the plasma portion of the blood sample to a point-of-care testing device. The blood separation 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 blood separation device is engageable with a blood testing device for closed transfer of a portion of the plasma portion from the blood separation device to the blood testing device. The blood testing device is adapted to receive the plasma portion to analyze the blood sample and obtain test results.

  • Publication number: 20130289524
    Abstract: A shieldable needle device includes a hub with and a needle cannula having a puncture tip extending from a forward end thereof, and a shield member in telescoping association with the hub. At least one of the hub and the shield member are adapted for relative axial movement with respect to the other between a first position in which the puncture tip of the needle cannula is exposed from a forward end of the shield member and a second position in which the puncture tip of the needle cannula is encompassed within the shield member. A drive member extends between the hub and the shield member, biasing the hub and the shield member axially away from each other. A packaging cover may further extend about the needle cannula, applying external pressure between the cooperating portions of the hub and the shield.
