Abstract
A medical bandage consists of a knit fabric made from loop yarns without inlaid yarns. The loop yarns are multifilament yarns having at least one elastic filament, a plurality of synthetic microfilaments and a plurality of cellulose or cellulosic filaments. The bandage has a linear and a non-linear stretching regime, with an operating point lying between them. When it is applied to a patient, it is elastically stretched to the operating point, which allows to generate reproducible, well defined compression forces.
Claims12
A medical bandage, wherein said bandage is formed by a knit fabric of loop yarns without inlaid yarns, wherein said loop yarns are multifilament yarns, each loop yarn comprising at least one first filament and a plurality of second filaments, wherein said first filament has higher elasticity than said second filaments and wherein, in a relaxed state of said first filament, said first filament is shorter than said second filaments,
- wherein said second filaments are of cellulose and/or a cellulosic material;
- wherein said loop yarns further comprise a plurality of third, synthetic filaments;
- and
- wherein said bandage is configured to be extended in a linear elastic manner from a relaxed position by approximately 30 percent in length until it reaches a non-linear elastic condition.
A method for manufacturing a bandage comprising:
- providing a knit fabric of loop yarns without inlaid yarns, wherein said loop yarns are multifilament yarns, each loop yarn comprising at least one first filament and a plurality of second filaments, wherein said first filament has higher elasticity than said second filaments and wherein, in a relaxed state of said first filament, said first filament is shorter than said second filaments;
- and
- further comprising the step of knitting said loop yarns while said loop yarns are elastically stretched by at least 30% in length.
A medical bandage, wherein said bandage is formed by a knit fabric of loop yarns without inlaid yarns, wherein said loop yarns are multifilament yarns, each loop yarn comprising at least one first filament and a plurality of second filaments, wherein said first filament has higher elasticity than said second filaments and wherein, in a relaxed state of said first filament, said first filament is shorter than said second filaments, the medical bandage being configured to be extended by approximately 30% in length when applying the medical bandage to a limb of a user, the extension of the medical bandage by approximately 30% in length being at the end of the linear elastic region of the extension of the medical bandage.
