Definitions
- Knitted fabric as part of bandages or other orthopedic aids are Knitted fabric as part of bandages or other orthopedic aids
- the invention relates to a knitted fabric as part of bandages or other orthopedic aids according to the preamble of claim 1.
- a joint bandage which has an insert in the flexion area of the joint, which is seamlessly incorporated into the bandage and is made with a different knitting technique than the bandage.
- This knitting technique allows the stretchability of the insert in the longitudinal direction of the band to be made approximately twice as large as that of the bandage material.
- the knitted fabric according to the invention can adapt particularly well to body movements without the knitted material being compressed in some areas and thus forming wrinkles.
- the disadvantages of known bandages with regard to the formation of wrinkles can thus be effectively avoided.
- two stitches of the basic knitted structure are preferably bridged by the bridging stitch.
- the bridging stitches are alternately provided on both sides of the knitted fabric in the knitting direction, so that the rows of stitches of the bridged stitches of the basic structure of the knitted fabric form an accordion-like structure as far as possible with the formation of a rib-like pattern on both sides of the knitted fabric in the relaxed state of the knitted fabric the bridging stitches can be pulled together.
- the knitted fabric then has the smallest possible expansion in the relaxed state and can accordingly be stretched relatively far.
- a mesh of the basic knitted structure is provided for easier production of the knitted fabric according to the invention on a knitting machine between two bridging stitches in the knitting direction.
- Claim 5 describes an advantageous thread selection.
- the knitted fabric according to the invention can particularly preferably be used in the joint area of a bandage. It can be used particularly advantageously in the flexion area of a knee joint, so that it is stretched far when the knee is extended. On account of its enormous elastic stretchability, the knitted fabric according to the invention can then contract strongly when the knee is bent without being compressed and could form undesirable folds which greatly disrupt the wearing of a bandage.
- the bandage can be produced together with the knitted fabric according to the invention in one operation on a knitting machine.
- the knitted fabric according to the invention is advantageously lenticular.
- the knitted fabric according to the invention is preferably designed such that, according to claim 10, it is elastically extensible in the knitting direction to at least 4 times its length.
- FIG. 1 shows a graphically illustrated joint bandage with a knitted fabric according to the invention as part of this bandage
- FIG. 2 shows a schematic cross-sectional representation of the knitted fabric according to the invention, seen on an enlarged scale along the line II / II of FIG. 1;
- FIG. 3 shows a representation similar to FIG. 2, showing the knitted fabric according to the invention in the stretched state
- Fig. 5 is a schematic side view of the bandage in different flexion positions.
- FIG. 1 shows a knee brace 10 in view.
- an insert 12 is incorporated into the bandage 10, which is elastically extensible in the longitudinal direction of the bandage.
- the insert 12 is in the flat state of the Bandage 10 is approximately lenticular, so that when the joint is flexed and stretched around vertices 14 and 16, it stretches like a pulling harriionic in the direction of arrow 18 or the longitudinal direction of the bandage and contracts again while avoiding wrinkling.
- the insert 12 consists of a knitted fabric 20 according to the invention, shown schematically in cross section in FIGS. 2 and 3.
- This knitted fabric 20 is made up of threads 22 and 24 of different elasticity, the thread of lower elasticity 22 preferably being a textured polyamide filament thread and the thread larger Elasticity 24 is preferably a rubber thread.
- a textured polyamide filament thread 22 is known under the trademark Helanca, so that in the following this thread 22 of lower elasticity will be referred to as Helanca thread 22 for the sake of simplicity.
- the knitted fabric 20 is constructed from a basic knitted fabric structure which is formed from stitches 26, 28, 30, 32 made from Helanca threads. Seen in the knitting direction 34, at least one helanca stitch of the basic knitted structure is bridged by a knitted bridging stitch 36 made of the elastic thread 24. In the exemplary embodiment shown, two Helanca meshes 26 and 28 or 30 and 32 are bridged by the bridging mesh 36 and 38, respectively. One bridging mesh 36 lies on one side of the basic knitted structure of Helanca meshes and the other bridging mesh 38 lies on the other side.
- the bridging meshes 36 and 38 are formed by means of the rubber thread 24, which is knitted under pretension, so that in the relaxed state of the knitted fabric 20 according to the invention the bridging stitches 36 and 38 contract and thereby the bridged Helanca stitches 26 and 28 or 30 and 32 are “folded in” like an accordion Through this folding, the rows of stitches of the Helanca stitches 26 and 28 or 30 and 32 form ribs 40 and 42 transversely to the knitting direction (arrow 34).
- the structure of the knitted fabric explained has the effect that when the inventive knitted fabric 20 is stretched in the knitting direction 34, the bridging stitches 36 and 38 are pulled apart and, at the same time, the Helanca stitches 26 and 28 or 30 and 32 forming the ribs 40 and 42 are “unfolded” or flattened that the knitted fabric 20 is "smoothed” as such and widened accordingly (see FIG. 3).
- the bridging stitches 26 and 36 are pulled together, the ribs 40 and 42 are inevitably set up again or the accordion-like stitches 26 to 32 are folded in like an accordion.
- the knitted fabric 20 according to the invention is preferably manufactured according to a knitting pattern, as is shown schematically in FIG. 4.
- the sequence of the work steps for the production of the knitted fabric 20 according to the invention on a knitting machine is shown in FIG. 4 from bottom to top.
- a first step Helanca stitches are knitted on needles 44 of a first of two needle beds.
- a row of stitches is knitted on the needles 44 and the needles 46 of a second needle bed by means of the rubber thread 24 (second work step).
- the rubber stitches knitted on the second needle bed each form the bridging stitch 36 according to FIGS. 2 and 3.
- steps 3 and 4 the stitches 26 and 28 are knitted from the Helanca thread 22.
- the Helanca stitches 28 hanging on the needles 44 are transferred to the needles 46 of the second needle bed, and in a sixth step the transferred Helanca stitches 28 together with those already on the needles 46 , knitted by the rubber thread 24, rubber stitches together with the Helanca thread 22.
- the further work steps 7 to 10 correspond to the work steps 2 to 5 explained, but now the function of the two needle beds is reversed.
- step 7 the bridging stitch 38 and in steps 8 and 9, the Helanca stitches 30 and 32 are formed.
- Steps 1 and 6 serve only to knit the stitches on the respective needles 44 and 46, since otherwise there would be too many threads on the individual needles without the knitting. The stitches resulting from the knitting are not shown in FIGS. 2 and 3 for the sake of simplicity.
- the knitted fabric 20 according to the invention can be elastically stretched to approximately 4 1/2 times its original length when appropriate thread elasticities are selected in the knitting direction.
- the knitted fabric 20 according to the invention has an elongation curve that runs relatively flat. The force required to stretch the knitted fabric according to the invention increases only insignificantly as the stretch increases.
- the knitted fabric according to the invention can, as shown in FIG. 1, be worked into a bandage like an inlay.
- the bandage 10 and the fabric 20 according to the invention forming the insert 12 have the same threads 22 and 24.
- a weft thread made of rubber is expediently knitted into the bandage material in a known manner.
- the knitted fabric 20 according to the invention advantageously has the shape shown in FIG. 1.
- the knitted fabric according to the invention is essentially lenticular, but asymmetrical to a connecting line of the vertices 14 and 16.
- the knitted fabric 20 according to the invention extends into corner areas 50 and 52, shown in broken lines, so that the strongly pronounced tendon attachments of the flexion muscles of the thigh (sciatic-crural musculature) are spared, since they are very friction and pressure sensitive are sensitive.
- 5 shows in a sketch the excellent adaptation of the bandage in the bending position of the knee without bulging.
- the knitted fabric according to the invention has the following medical advantages:
- the knitted fabric according to the invention is more breathable than previously known, whereby a better heat exchange is possible and no skin irritation due to moisture accumulating under the bandage can occur. This also results in less irritation when there is a tendency to eczema.
- the knee area can dry out more quickly, particularly during sporting activities.
- the highly elastic knitted fabric according to the invention relieves the entire arterial and venous area in the hollow of the knee, which brings about a significant improvement in the vascular situation, particularly in patients with poor circulation. In particular, the risk of thrombosis is reduced, since a metered pressure can be built up in the hollow of the knee with the aid of the knitted fabric according to the invention.
- the defined force of the knitted fabric according to the invention also makes it painless
