  • Publication number: 20200146604
    Abstract: A specimen transfer device adapted to receive a blood sample is disclosed. The specimen transfer device includes a housing and an actuation member. A deformable material is disposed within the housing and is deformable from an initial position in which the material is adapted to hold the sample to a deformed position in which at least a portion of the sample is released from the material. A viscoelastic member is disposed within the housing between the material and the housing and between the material and the actuation member. The viscoelastic member is engaged with the actuation member and the material such that movement of the actuation member from a first position to a second position deforms the material from the initial position to the deformed position.

  • Patent number: 10646149
    Abstract: A specimen collection assembly (100) including a flow control member (106) for adjustably altering a flow path is disclosed. In one configuration, the flow control member (106) defines a regulation channel (166) in fluid communication with a lumen of a cannula (112), wherein the flow control member (106) is configured to adjustably alter an effective flow distance between the lumen of the cannula (112) and an interior of an evacuated collection container. In another configuration, the flow control member (106) is positioned to vary an effective cross-sectional area of at least one of an inlet port (346) and an outlet port (350) adapted to be in fluid communication with the lumen and the evacuated collection container.

  • Patent number: 10639636
    Abstract: A container for storing a biological sample is disclosed. The container includes a housing having a closed end, an open end, and a sidewall extending therebetween defining a container interior. The container has a removable closure for enclosing the open end of the housing and a sample holder for housing a biological sample detachably connected to the closure and insertable within the container interior. A port is disposed within the closure adjacent the sample holder to allow fluid to pass therethrough into the container interior. An injection device for engaging the port may also be provided. A first fluid may be initially provided within the container interior and a second fluid may be subsequently injected by the injection device through the port into the container interior.

  • Publication number: 20200100717
    Abstract: A shieldable needle device including a drive member is disclosed. The drive member is extendable between a biased position and an extended position for moving a tip guard from an first position to a second position in which the tip guard shields a distal end of the needle cannula. The shieldable needle device includes a pair of wings extending laterally from opposing sides of the hub that are movable between a laterally extending position and a dorsal position. With the wings in the dorsal position, the wings retain the drive member in the biased position thereby maintaining the tip guard in the first position. Movement of the wings from the dorsal position to the laterally extending position releases retainment of the drive member. A second drive member may be included.

  • Publication number: 20190274609
    Abstract: A biological fluid sampling transfer device adapted to receive a multi-component blood sample is disclosed. After collecting the blood sample, the biological fluid sampling transfer device is able to separate a plasma portion from a cellular portion. After separation, the biological fluid sampling transfer device is able to transfer the plasma portion of the blood sample to a point-of-care testing device. The biological fluid sampling transfer 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 sampling transfer device is engageable with a blood testing device for closed transfer of a portion of the plasma portion from the biological fluid sampling transfer 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.
