Abstract
A therapeutic medical garment including a knitted welt proximate one end thereof with a surface adapted for residing against the wearer's skin. The garment includes a ground yarn and a plurality of raised, skin-engaging stabilizer elements, such as elongate bars extending in spaced-apart relation around an inner surface of the welt and along a longitudinal axis of the garment to reduce a tendency of the welt to roll over on itself.
Claims13
A therapeutic medical garment having a graduated pressure profile along its length, and comprising:
- (a) a knitted body;
- (b) a welt having a separate outer surface and an inner surface joined at and defining an upper end of the garment, including a ground yarn and a plurality of stabilizer elements extending in spaced-apart relation around the welt and along a longitudinal axis of the garment to reduce a tendency for the welt to roll onto itself;
- and
- (c) an anti-slip portion formed intermediate the body and the welt and having a textured inner surface adapted for residing in a non-slip condition against a wearer's skin to increase anti-slip properties of the garment, wherein
- the garment comprises a circular-knitted stocking for being worn on a leg, and the welt comprises a plurality of knitting revolutions, wherein the stabilizer elements comprise a knitted structure extending substantially longitudinally along a length of the welt on an inner surface thereof, and formed from:
- (a) a first feed comprising a jersey knit on all needles with a plurality of spaced-apart stabilizer bar yarns patterned into the welt around a circumference of the welt;
- (b) a second feed comprising a jersey knit on all needles with a plurality of spaced-apart float yarns patterned into the welt to provide additional bulk to the stabilizer elements;
- (c) a third feed comprising a jersey knit on all needles with a plurality of spaced-apart stabilizer bar yarns patterned into the welt around the circumference of the welt;
- and
- (d) a fourth feed comprising an inlaid 1×1 rib knitted at tuck height.
A therapeutic medical garment having a graduated pressure profile along its length, and comprising a knitted welt proximate one end thereof with a surface adapted for residing against the wearer's skin constructed of a ground yarn and a plurality of raised, skin-engaging stabilizer elements extending in spaced-apart relation around an inner surface of the welt to reduce a tendency of the welt to roll on itself, wherein the garment comprises a circular-knitted stocking for being worn on a leg, the stabilizer elements comprise a knitted structure extending substantially longitudinally along a length of the welt on an inner surface thereof, and include in a plurality of knitting revolutions forming the circular-knitted welt formed from:
- (a) a first feed comprising a jersey knit on all needles with a plurality of spaced-apart stabilizer bar yarns patterned into the welt around a circumference of the welt;
- (b) a second feed comprising a jersey knit on all needles with a plurality of spaced-apart float yarns patterned into the welt to provide additional bulk to the stabilizer elements;
- (c) a third feed comprising a jersey knit on all needles with a plurality of spaced-apart stabilizer bar yarns patterned into the welt around the circumference of the welt;
- and
- (d) a fourth feed comprising an inlaid 1×1 rib knitted at tuck height.
A therapeutic medical garment having a graduated pressure profile along its length, and comprising a knitted garment having:
- (a) a knitted welt proximate one end of the garment with an inwardly facing layer having a surface adapted for residing against a wearer's skin and including a ground yarn and a plurality of raised, skin-engaging stabilizer elements positioned on and extending in spaced-apart relation around an inwardly facing surface of the welt;
- (b) an outwardly facing layer;
- and
- (c) either the outwardly facing layer or the inwardly facing layer being configured so that in a use condition on a limb of a wearer a modulus of elasticity parallel to a longitudinal axis of the inwardly facing layer is greater than a modulus of elasticity parallel to the longitudinal axis of the outwardly facing layer, whereby a resistance of the selected outwardly or inwardly facing layer against a lengthening stress parallel to the longitudinal axis is increased such that if the welt begins to roll back on itself, the outwardly or inwardly facing layer will lengthen, and the resistance against a lengthening increases, the welt becomes more stable and is prevented from deflecting outwardly and rolling over itself.
