  • Publication number: 20190216444
    Abstract: Apparatus and methods are provided to remove biopsy specimens from a bone and/or associated bone marrow using a powered driver and an intraosseous (IO) needle set. The powered driver may rotate the IO needle set at an optimum speed to obtain a biopsy sample of bone and/or bone marrow. Apparatus and methods may also be provided for aspiration of bone marrow and/or stem cell transplant procedures. The apparatus may include a powered driver, a coupler assembly, a containment bag or sterile sleeve and various IO needles and IO needle sets with associated hubs and/or hub assemblies. Each IO needle set may include a cannula or catheter and an associated trocar stylet with respective tips operable to penetrate a bone and/or bone marrow with minimum trauma to a patient. Each hub assembly may be used to releasably dispose a respective stylet within an associated generally hollow cannula. Some coupler assemblies and/or hub assemblies may also be used with manual drivers.

  • Patent number: 4865197
    Abstract: A transportation container (68,44) for transporting items or enclosures (72) requiring electrostatic protection includes a box (44) lined with electrically conductive bubble layer material (58) which protrudes from open seams (66) and which is also electrically accessible through an aperture (28) in registration with an opening (42) when the box (44) is contained within the sleeve (68). The accessibility of the electrically conducting bubble sheet material (58) allows for either deliberate discharge to ground potential of the bubble material (58) via the aperture (28) or provides ample opportunity for accidental discharge to ground by virtue of protrusion of the bubble material (58) through the open seams (66). The bubbles of the material (58) distort and burst to accommodate a range of enclosures from very small to quite large by virtue of the fact that the tips of the bubbles (62) just touch without compression when the box (44) is closed.
