The present invention relates to a compression stocking (10) which is divided into at least two parts, making it easier to put the stocking on and to take it off. A first part (12) has a foot portion (16), an ankle portion (18) which extends above the malleolus 14, and a first overlap portion (24) which is above the ankle portion, and is so formed as to exert in use a pressure which is reduced compared to a pressure exerted by the ankle portion. A second part (30) is tubular and has a second overlap portion (32) and a leg portion (34) which extends in use up the leg from the overlap portion to surround at least part of the lower leg. In use the first overlap portion is able to be placed within the second overlap portion, the compression stocking providing a pressure which reduces progressively up the leg. An outer surface of the first part and an inner surface of the second part are formed in a manner which provides a sufficiently low coefficient of friction to enable the compression stocking to be put on by putting the first part on first, and then drawing the second part over the first part and pulling it up the leg to bring the second overlap portion into position around the first overlap portion, so that passage of the second part over the foot and ankle is facilitated by the first part.
A compression stocking comprising a first part comprising:
A compression stocking as claimed in any preceding claim in which the first part is of closed toe form.
A compression stocking as claimed in any preceding claim in which the first overlap portion has a lower edge which is above the malleoli in use.
A compression stocking as claimed in any preceding claim in which the lower edge of the first overlap portion is between 6 and 8 centimetres above the summit of the medial malleolus in use.
A compression stocking as claimed in any preceding claim in which, in use, the first and second overlap portions contribute substantially equal pressures.
A compression stocking as claimed in any preceding claim in which the second overlap portion is deeper, in a direction extending along the leg in use, than the first overlap portion.
A compression stocking as claimed in any preceding claim in which an area of the foot portion in which is in the vicinity of the Achilles heel in use is formed to have a lower elastic stiffness than material surrounding it, and so to stretch preferentially during dorsiflexion.
A method of putting on a compression stocking, comprising forming the compression stocking in at least two parts, a first part of the compression stocking comprising
A compression stocking substantially as herein described with reference to, and as illustrated in, any of the accompanying drawings.
