Definitions

  • the invention relates to a compression article produced on a knitting machine, wherein in each case the number of stitches per row of stitches is adapted to the radial circumference of the body part to be treated by the compression article.
  • compression articles are used in the form of compression stockings, compression gloves, foot caps and the like.
  • Other elastic articles are joint bandages or combustion bandages. In sports supportive bandages are used to protect against injury and sometimes also to increase performance.
  • these articles are produced predominantly as knits, whereby production on a flat knitting machine is the rule.
  • the article is made as a flat knit, the longitudinal edges are then sewn together, so that the desired three-dimensional article results.
  • the flat-lying knit is knitted in areas where the body part to be treated has a larger circumference with more stitches per row of stitches than in areas of smaller circumference.
  • the stitch increases and the stitch reductions take place at the edges of the flat knitted fabric.
  • the shape of the compression article thus only imperfectly replicates the anatomy of the body part. In particular, the longitudinal axes of the compression article and the body part do not coincide.
  • the invention is therefore based on the object of providing compression articles with an improved fit.
  • the object is achieved by a compression article made from a knitting machine, in particular a flat knitting machine knitted fabric in which the number of stitches per row of stitches is adapted to the radial circumference of the body part to be treated by the compression article and which is characterized in that it has a plurality of circumferentially distributed locations around its circumference to conform to the shape of the body part to be treated.
  • stitches and / or stitches are reduced in a course and, moreover, the number of stitches in the wale direction varies over the circumference of the compression article and the compression article is thereby additionally adapted to the shape of the body part to be treated in the longitudinal direction of the body.
  • the compression article according to the invention is characterized in that increases in stitches and / or stitches are made at those peripheral locations at which the body part to be supported also undergoes a change in its circumference and not only in the region of the longitudinal seam of the article.
  • the longitudinal fit is improved by also varying the number of stitches in the wale direction of the compression article over its circumference.
  • a compression stocking according to the invention can have more courses in the calf area than in the tibial area. This not only allows a better fit of the compression article, but also a more even distribution of the compression pressure on the body part.
  • the three-dimensionally knitted article therefore has an improved fit as well as improved effectiveness.
  • the compression article may be knitted so that its central longitudinal axis coincides with the central longitudinal axis of the body part to be supplied. This makes it possible to achieve particularly uniform pressure conditions over the circumference of the body part.
  • the compression article is produced as a three-dimensional flat or circular knit. Through mesh accumulation in a central area of the knitted fabric creates a three-dimensional structure.
  • the compression article can also be made as a seamless tubular fabric and thereby obtain a three-dimensional shape. The step of the subsequent sewing together of the edges of the knitted fabric can then be omitted.
  • the compression article may additionally be fabricated using wicking techniques.
  • weaving techniques in conjunction with the distributed over the circumference mesh increase and / or decrease in mesh almost any three-dimensional structures can be produced.
  • the compression article may be formed of a plurality of strip-shaped sections, which are separated in the circumferential direction of the compression article by zones with mesh increases and / or decreases.
  • subsections can thus be produced in a technically relatively simple way compression articles in which a mesh increase and / or a mesh reduction is present at several circumferential locations.
  • the side edges of the sections may be parallel or not parallel to each other.
  • the division of the knitted fabric into sections, the number of stitches per row of stitches in the sections and the number of courses per section can be determined accordingly from the data obtained in the measurement of the body part to be supported.
  • the compression article may also be made at least partially using elastic yarns in a manner known per se.
  • the elastic threads may form the basic weave of the article and / or be involved as weft and / or warp threads.
  • compression pressure applied to the body part by the compression article decreases from the distal end of the article to the proximal end. This measure helps to drain lymphatic fluid to the heart and thus promotes the excretion of excess fluid from the body.
  • the compression article may be made of a double-faced or double-layered knit.
  • the knit may be made, for example, from an R-R bond. Or it may have several R-L layers, which are connected to each other surface or point.
  • the corrected basic section is produced by calculating a plurality of subsections, the subsections being separated from each other by zones in which the mesh number of the courses of the knitted fabric is reduced and / or increased.
  • the number of subsections can be predetermined or freely chosen.
  • the in the Fig. 1 and 2 Compression article 10 shown in the example shown is manufactured on a flat knitting machine and divided at the design stage into four sections 11, 12, 13 and 14, which define therebetween zones 15-18 in which a stitch increase and / or a mesh reduction takes place.
  • the four sections 11 to 14 are knitted with common thread guides, so that the in Fig. 2 shown, finished knit yields.
  • the representation in Fig. 1 but serves to better explain the manufacturing process of Article 10.
  • Each of the sections 11 to 14 is adapted in the zones 15 to 18 at the longitudinal edges of the sections 11 to 14 with respect to the mesh size in each course such that the finished compression fabric 10 is optimally adapted in shape to a body part to be supported.
  • measurement data of the body part are first used to select a basic cut for the compression article 10 from a set of available cuts, which is already close to the required shape of the compression article 10.
  • the sections of the sections 11 to 14 of this basic section are then corrected so that the fit of the assembled from the sections compression article 10 is adapted to the shape of the body part optimally.
