    Abstract

    The invention relates to a compression bandage comprising a first non-woven laser (1) and at least one second non-woven layer (2) connected in a planar manner to the first non-woven layer (1), wherein superabsorbent fibers are provided in the first non-woven laser.

    Claims

    1. A compression bandage comprising a first nonwoven layer and at least one second nonwoven layer, connected areally to the first nonwoven layer, wherein superabsorbent fibers are provided in the first nonwoven layer.

    2. The compression bandage of claim 1, wherein in the applied state the first nonwoven layer is directed toward a wearer of the compression bandage.

    3. The compression bandage of claim 1, wherein the first nonwoven layer is a thermofused nonwoven.

    4. The compression bandage of claim 1, wherein the second nonwoven layer is a thermobonded nonwoven.

    5. The compression bandage of claim 1, wherein the two nonwoven layers are connected to one another by means of stitchbonding methods via an elastic stitching thread.

    6. The compression bandage of claim 1, wherein the material of one or both of the layers is nonelastic.

    7. The compression bandage of claim 1, wherein the thickness of the first nonwoven layer is 0.6-1.2 mm.

    8. The compression bandage of claim 1, wherein the nonwoven material of the first nonwoven layer and/or second nonwoven layer comprises polyester.

    9. The compression bandage of claim 1, wherein the superabsorbent fibers consist of polyacrylate.

    10. The compression bandage of claim 5, wherein the elastic stitching thread is selected from a group composed of cotton spun crepe threads, cotton twisted crepe threads, textured polyamide yams, textured polyester yams, rubber threads or polyurethane elastane threads, and combinations thereof.

    11. The compression bandage of claim 1, wherein the compression bandage has a stretching threshold which indicates the maximum stretchability.

    12. The compression bandage of claim 11, wherein the maximum stretchability corresponds to a therapeutically mandated application pressure of the compression bandage on a limb of a wearer.

    13. The compression bandage of of claim 1, wherein a side of the compression bandage pointing away from the wearer has a cohesive coating.

    14. A compression bandage combination comprising a first compression bandage of which is the compression bandage of claim 1, and also a second compression bandage applied over the first compression bandage.

    15. The compression bandage combination of claim 14, wherein in the applied state, the first compression bandage exerts a working pressure and the second compression bandage a resting pressure on a limb.

    16. The compression bandage of claim 2, wherein in the applied state the first nonwoven layer is directed toward a wearer of the compression bandage and is configured as a cushioning layer.

    17. The compression bandage of claim 8, wherein the nonwoven material of the first nonwoven layer and/or second nonwoven layer consists of polyester.

    Description

    [0048] The invention is described in more detail below with reference to a drawing. Further advantages and features of the invention are additionally apparent from the rest of the application documents.

    [0049] In the drawing, FIG. 1 shows a method for producing a compression bandage of this kind.

    [0050] FIG. 1 depicts how a first nonwoven layer 2, provided with superabsorbent fibers, and a second nonwoven layer are each supplied as roll material. This first nonwoven layer 2 may consist of a nonwoven prefabricated with superabsorbent fibers, or may consist completely of superabsorbent fibers, or a nonwoven material may be covered with superabsorbent fibers in the facility 3. In the preferred case, the two nonwoven materials 1 and 2 are connected to one another in a stitchbonding method by means of a warp knitting machine, which carries the reference numeral 5; the elastifying agents 4, which in this case take the form of elastane threads and serve as warp threads, are supplied to the warp knitting machine 5. The stitchbonding method operates here with a hook, by means of which the layers are overstitched with the elastic stitching thread. The stitching thread is an elastically prestretched thread, which is introduced with a mandated stitch length and a mandated stitching thread tension, and which accordingly, after release of tension from the elastic material, results in a contraction of the plied assembly (fabric).

    [0051] Other elastifying agents may also be used and supplied, alternatively.

    [0052] If no stitchbonding method is used, a different facility 5 may be used, in which the plies are connected to one another and elastified.

    [0053] The material connected mutually via the elastic stitching thread in particular is then wound up to form a roll 6; optionally, this may be preceded by make-up in the longitudinal direction to form bandages.

    [0054] The compression bandages embodied in this way correspond in their characteristics to a short-stretch bandage, which initially exhibits approximately no increase in force on stretching, before then realizing an abrupt increase and hence a stretching threshold, with the stretching threshold here being situated within the range of the optimal therapeutic pressure, meaning that, on maximal stretching of the compression bandage, it is possible simultaneously to establish the optimal therapeutic pressure for compression therapy, when the bandage is applied with the aforementioned pre-tension.

    [0055] By virtue of the superabsorbent fibers contained in the first nonwoven layer, wound exudates can be bound and can be led away from the wound. As a result, wound healing can be positively influenced, since in this way enzymes which can have an adverse effect on healing are removed from the wound.
