  • Publication number: 20190117231
    Abstract: A sleeve for use with a tourniquet cuff to protect a patient's limb from tourniquet-related injury includes a stretchable body extending longitudinally over a sleeve length between a proximal end and a distal end. The body has a tubular shape, and the sleeve length is greater than a width of the tourniquet cuff. The body tapers from the proximal end to the distal end such that a proximal end circumference is greater than a distal end circumference. The body is formed to apply substantially uniform pressure to the patient's limb from the proximal end of the sleeve to the distal end of the sleeve varying only within a predetermined pressure range.
    Type: Application

  • Publication number: 20180140306
    Abstract: A low-cost contour cuff for surgical tourniquet systems comprises: a sheath containing an inflatable bladder, the sheath having an arcuate shape, an outer surface and a centerline equidistant between first and second side edges; a securing strap non-releasably attached to the outer surface and formed of substantially inextensible material having a shape that is predetermined and substantially flat, wherein the strap includes a bending portion near a first strap end and a fastening portion near a second strap end, and wherein the bending portion is adapted to allow twisting of the bending portion out of the substantially flat shape to facilitate positioning of the fastening portion into any of a plurality of positions in the substantially flat shape; and fastening means for releasably attaching the fastening portion of the securing strap to the outer surface whenever the sheath is curved into a position for surrounding a limb.
