Abstract
Abstract An elongated tubular protective cover for a cast enclosed body limb portion is provided and at least one end of the protective cover is open and includes an elongated flexible seal band of water impervious material carried by one end of the cover and for wrapping about that end and the adjacent limb portion disposed outwardly of the cover in an edge overlapping spiral manner in order to form a fluid tight seal between the cover and the adjacent limb portion. The cover includes inner and outer telescopingly engaged tubular member constructed of flexible fluid impervious material and the inner tubular member includes features rendering it pervious to air flow therethrough. Also, at least one moisture absorptive spacing member is disposed between the outer and inner surfaces of the inner and outer tubular members. A first form of cover is closed at the end thereof remote from the flexible seal band whereby the terminal end portion of a body limb may be fully enclosed within the cover and a second form of cover is open at both ends with each end equipped with a flexible seal band.
