  • Patent number: 5916190
    Abstract: A bandage for wrapping an amputee's stump to reduce the potential for swelling and deformation of the stump after amputation. The bandage includes an elongate wrap, at least one strip attached to the wrap and means for releasably fastening the wrap around the stump. The wrap has a length sufficient to wrap around the stump and a resilience sufficient to retain the bandage adjacent an end of the stump when the wrap is stretched around the stump. The strip extends laterally outward from the wrap. The strip has a width generally equal to the diameter of the stump and a length sufficient to wrap around the end of the stump when the wrap is wrapped around the stump adjacent the end of the stump. The strip is sufficiently resilient to compress the stump to reduce the potential for swelling and deformation of the stump when the strip is stretched around the end of the stump.

  • Patent number: 4832007
    Abstract: A pillow of resilient material has a generally rotatable portion (cervical roll) for supporting the cervical region of a user. With a user's neck received across the pillow cervical roll and the user's head received on the pillow, rotation of the cervical roll in conjunction with collapse of angled chambers defined within the resilient pillow establishes traction in the cervical region of the user. Once its internal chambers are essentially fully collapsed, the pillow provides a generally continuous support medium for optimized resilient support of the user's neck and head, while maintaining a degree of cervical region traction with natural cervical curvature achieved through curved support of the user's cervical region across the cervical roll of the pillow.
