Description

Die Erfindung bezieht sich auf einen auf einer Strickmaschine erzeugten Kompressionsartikel, bei dem jeweils die Maschenanzahl je Maschenreihe dem radialen Umfang des durch den Kompressionsartikel zu behandelnden Körperteils angepasst ist.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.

Insbesondere zur Vermeidung oder Behandlung von Ödemen, Varikosen, venöser Insuffizienz sowie nach venenchirurgischen Eingriffen werden solche Kompressionsartikel in Form von Kompressionsstrümpfen, Kompressionshandschuhen, Fußkappen und dergleichen eingesetzt. Weitere elastische Artikel sind Gelenkbandagen oder auch Verbrennungsbandagen. Im Sport werden stützende Bandagen zum Schutz vor Verletzungen und teilweise auch zur Leistungserhöhung eingesetzt.In particular, for the prevention or treatment of edema, varicose veins, venous insufficiency and after vein surgery, such 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.

Diese Artikel werden wegen der guten elastischen Eigenschaften vorwiegend als Gestricke hergestellt, wobei eine Fertigung auf einer Flachstrickmaschine die Regel ist. Der Artikel wird dabei als flachliegendes Gestrick hergestellt, dessen Längsränder anschließend zusammengenäht werden, sodass sich der gewünschte dreidimensionale Artikel ergibt. Das flachliegende Gestrick wird dabei in Bereichen, in denen der zu behandelnde Körperteil einen größeren Umfang aufweist mit mehr Maschen je Maschenreihe gestrickt als in Bereichen eines geringeren Umfangs. Die Maschenzunahmen und die Maschenminderungen erfolgen dabei an den Rändern des flachliegenden Gestricks. Dies bedeutet, dass nach dem Schließen der Längsnaht des flachliegenden Gestricks diese Längsnaht einen gekrümmten Verlauf hat, während der gegenüberliegende Umfangsbereich des Kompressionsartikels in Längsrichtung absolut gerade verläuft. Die Form des Kompressionsartikels bildet somit die Anatomie des Körperteils nur unvollkommen nach. Insbesondere fallen die Längsachsen des Kompressionsartikels und des Körperteils nicht zusammen.Because of their good elastic properties, 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. This means that after closing the longitudinal seam of the flat knitted fabric, this longitudinal seam has a curved course, while the opposite peripheral region of the compression article runs absolutely straight in the longitudinal direction. 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.

Bei Patienten sind Ausbeulungen und Formänderungen am betroffenen Körperteil jedoch an allen Umfangsstellen möglich. Ein Unterschenkel eines solchen Patienten kann daher nicht nur die muskelbedingte Umfangserweiterung im Wadenbereich, sondern auch Ausbeulungen im Schienbeinbereich aufweisen. Daher sind die bisher erhältlichen Kompressionsartikel selbst bei einem genauen Vermessen des Körperteils und einer Maßanfertigung des Kompressionsartikels nicht ausreichend passend. Zudem ist die heute eingesetzte, oben beschriebene Flachstrick-Technologie für die Herstellung derartiger Produkte nur bedingt geeignet.In patients, however, bulges and deformations of the affected body part are possible at all circumferential locations. Therefore, a lower leg of such a patient can not only have the muscle-related peripheral expansion in the calf area, but also bulges in the tibial region. Therefore, the hitherto available compression articles are not sufficiently suitable even for a precise measurement of the body part and a customization of the compression article. In addition, the flat knit technology described above is only of limited use for the production of such products.

Der Erfindung liegt daher die Aufgabe zugrunde, Kompressionsartikel mit einer verbesserten Passform zur Verfügung zu stellen. Die Aufgabe wird gelöst durch einen Kompressionsartikel, hergestellt aus einem auf einer Strickmaschine, insbesondere einer Flachstrickmaschine erzeugten Gestrick, bei dem jeweils die Maschenanzahl je Maschenreihe dem radialen Umfang des durch den Kompressionsartikel zu behandelnden Körperteils angepasst ist und der dadurch gekennzeichnet ist, dass er zur Anpassung an die Form des zu behandelnden Körperteils in Umfangsrichtung mehrere über seinen Umfang verteilte Stellen aufweist, an denen in einer Maschenreihe eine Maschenzunahme und/oder eine Maschenminderung erfolgt, und dass außerdem die Anzahl der Maschen in Maschenstäbchenrichtung über den Umfang des Kompressionsartikels variiert und der Kompressionsartikel dadurch zusätzlich der Form des zu behandelnden Körperteils in Körperteillängsrichtung angepasst ist.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 In addition, 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.

Der erfindungsgemäße Kompressionsartikel zeichnet sich dadurch aus, dass Maschenzunahmen und/oder Maschenminderungen an denjenigen Umfangsstellen erfolgen, an denen das zu stützende Körperteil ebenfalls eine Änderung seines Umfangs erfährt und nicht mehr nur im Bereich der Längsnaht des Artikels. Außerdem ist die Passform in Längsrichtung verbessert, in dem auch die Anzahl der Maschen in Maschenstäbchenrichtung des Kompressionsartikels über dessen Umfang variiert. So kann beispielsweise ein Kompressionsstrumpf gemäß der Erfindung im Wadenbereich mehr Maschenreihen aufweisen als im Schienbeinbereich. Damit lässt sich nicht nur eine bessere Passform des Kompressionsartikels, sondern auch eine gleichmäßigere Verteilung des Kompressionsdrucks auf den Körperteil erzielen. Der dreidimensional gestrickte Artikel hat daher neben einer verbesserten Passform auch eine verbesserte Wirksamkeit.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. In addition, the longitudinal fit is improved by also varying the number of stitches in the wale direction of the compression article over its circumference. Thus, for example, 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.

Bevorzugt kann der Kompressionsartikel so gestrickt sein, dass seine zentrale Längsachse mit der zentralen Längsachse des zu versorgenden Körperteils übereinstimmt. Dadurch lassen sich besonders gleichmäßige Druckverhältnisse über den Umfang des Körperteils erreichen.Preferably, 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.

Weiter ist es von Vorteil, wenn der Kompressionsartikel als dreidimensionales Flach- oder Rundgestrick hergestellt ist. Durch Maschenanhäufungen in einem mittleren Bereich des Gestricks entsteht ein dreidimensionales Gebilde. Der Kompressionsartikel kann aber auch als ein nahtloses Schlauchrund-Gestrick hergestellt werden und dadurch eine dreidimensionale Form erhalten. Der Schritt des anschließenden Zusammennähens der Ränder des Gestricks kann dann entfallen.Furthermore, it is advantageous if 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. However, 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.

Vorzugsweise kann der Kompressionsartikel zusätzlich unter Verwendung von Spickeltechniken hergestellt sein. Mit Spickeltechniken in Verbindung mit der über den Umfang verteilten Maschenzunahme und/oder Maschenabnahme lassen sich nahezu beliebige dreidimensionale Strukturen herstellen.Preferably, the compression article may additionally be fabricated using wicking techniques. With 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.

Bei einer bevorzugten Ausgestaltung kann der Kompressionsartikel aus mehreren streifenförmigen Teilabschnitten gebildet sein, die in Umfangsrichtung des Kompressionsartikels durch Zonen mit Maschenzunahmen und/oder Maschenabnahmen voneinander getrennt sind.In a preferred embodiment, 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.

Je nach der Anzahl der Teilabschnitte lassen sich somit auf technisch relativ einfache Weise Kompressionsartikel herstellen, bei denen eine Maschenzunahme und/oder eine Maschenminderung an mehreren Umfangsstellen vorhanden ist. Die Seitenränder der Teilabschnitte können dabei parallel oder auch nicht parallel zueinander verlaufen.Depending on the number of 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.

Außerdem können zumindest einige der Teilabschnitte eine unterschiedliche Anzahl von Maschenreihen bzw. eine unterschiedliche Länge der Maschenstäbchen (= Anzahl von Maschen pro Maschenstäbchen) aufweisen, um den Kompressionsartikel auch an die Kontur des Körperteils in dessen Längsrichtung gut anpassen zu können.In addition, at least some of the sections may have a different number of courses or a different length of wales (= number of stitches per wale) in order to adapt well to the contour of the body part in the longitudinal direction of the compression article.

Vorzugsweise kann dabei die Aufteilung des Gestricks in Teilabschnitte, die Maschenzahl je Maschenreihe in den Teilabschnitten und die Anzahl von Maschenreihen je Teilabschnitt entsprechend aus bei der Vermessung des zu stützenden Körperteils gewonnenen Daten bestimmt werden.Preferably, 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.

Der Kompressionsartikel kann außerdem in an sich bekannter Weise zumindest teilweise unter Verwendung von elastischen Garnen hergestellt sein. Die elastischen Fäden können dabei die Grundbindung des Artikels bilden und/oder als Schuss- und/oder Kettfäden eingebunden sein.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.

Bei bestimmten Ausführungsformen ergeben sich weitere Vorteile, wenn der auf den Körperteil durch den Kompressionsartikel ausgeübte Kompressionsdruck vom distalen Ende des Artikels zum proximalen Ende hin abnimmt. Diese Maßnahme unterstützt das Ableiten von Lymphflüssigkeit zum Herz hin und begünstigt damit das Ausscheiden überschüssiger Flüssigkeit aus dem Körper.In certain embodiments, further advantages are provided when the 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.

Der Kompressionsartikel kann aus einem doppelflächigen oder doppellagigen Gestrick hergestellt sein. Das Gestrick kann beispielsweise aus einer R-R-Bindung hergestellt sein. Oder es kann mehrere R-L-Lagen aufweisen, die flächig oder punktuell miteinander verbunden sind.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.

Die Erfindung betrifft außerdem ein erstes Verfahren zur Herstellung eines Kompressionsartikels auf einer Strickmaschine, insbesondere einer Flachstrickmaschine, das gekennzeichnet ist durch die Schritte:

  • Vermessen des durch den Kompressionsartikel zu stützenden Körperteils an einzelnen Messpunkten;
  • Auswahl eines Grundschnittes für den Kompressionsartikel aus einem Katalog, dessen Maße am besten mit dem vermessenen Körperteil übereinstimmen;
  • Korrektur der Maschenzahl der Maschenreihen und der Anzahl der Maschen in den einzelnen Maschenstäbchen des Grundschnittes entsprechend den Maßen des Körperteils zwischen den Messpunkten;
  • Stricken des korrigierten Grundschnittes auf einer Strickmaschine, insbesondere einer Flachstrickmaschine.
The invention also relates to a first method for producing a compression article on a knitting machine, in particular a flat knitting machine, which is characterized by the steps:
  • Measuring the body part to be supported by the compression article at individual measurement points;
  • Selection of a basic section for the compression article from a catalog whose dimensions correspond best to the measured part of the body;
  • Correction of the number of stitches of the courses and the number of stitches in the individual wales of the basic cut corresponding to the dimensions of the body part between the measuring points;
  • Knitting the corrected basic section on a knitting machine, in particular a flat knitting machine.

Dieses Verfahren eignet sich insbesondere zur Herstellung von Kompressionsartikeln mit sehr guter Passform. Dabei ist es von Vorteil, wenn der korrigierte Grundschnitt durch Berechnen mehrerer Teilabschnitte hergestellt wird, wobei die Teilabschnitte jeweils durch Zonen, in denen die Maschenzahl der Maschenreihen des Gestricks vermindert und/oder vergrößert wird, voneinander getrennt sind. Die Anzahl der Teilabschnitte kann vorgegeben sein oder frei gewählt werden.This method is particularly suitable for the production of compression articles with a very good fit. It is advantageous if 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.

Ein alternatives Verfahren zur Herstellung eines Kompressionsartikels auf einer Strickmaschine, insbesondere einer Flachstrickmaschine nach der Erfindung ist gekennzeichnet durch die Schritte:

  • Vermessen des durch den Kompressionsartikel zu stützenden Körperteils durch Scannen des Körperteils;
  • Berechnung der notwendigen Maschenanzahl je Maschenreihe entsprechend dem gemessenen Umfang des Körperteils im durch die Maschenreihe abgedeckten Bereich des Körperteils;
  • Berechnung derjenigen Stellen innerhalb jeder Maschenreihe, an denen eine Maschenzu- und/oder -abnahme im Vergleich zur vorangehenden Maschenreihe erforderlich ist, sodass die zentrale Längsachse des Kompressionsgestricks mit der zentralen Längsachse des Körperteils übereinstimmt;
  • Berechnung der notwendigen Anzahl von Maschen je Maschenstäbchen des Kompressionsartikels zur Abdeckung des Körperteils in dessen Längsrichtung;
  • Stricken des Kompressionsartikels auf einer Flachstrickmaschine unter Verwendung der berechneten Maschenzahlen je Maschenreihe, den berechneten Stellen einer Maschenzu- und/oder -abnahme in den Maschenreihen und den berechneten notwendigen Anzahlen von Maschen je Maschenstäbchen.
An alternative method for producing a compression article on a knitting machine, in particular a flat knitting machine according to the invention, is characterized by the steps:
  • Measuring the body part to be supported by the compression article by scanning the body part;
  • Calculation of the necessary number of stitches per stitch row corresponding to the measured circumference of the body part in the region of the body part covered by the row of stitches;
  • Calculation of those points within each course where a stitch increase and / or decrease is required compared to the previous course, such that the central longitudinal axis of the compression knit coincides with the central longitudinal axis of the body part;
  • Calculating the necessary number of stitches per wale of the compression article to cover the body part in its longitudinal direction;
  • Knitting of the compression article on a flat knitting machine using the calculated number of stitches per course, the calculated points of stitch feeding and / or taking in the courses and the calculated necessary number of stitches per wale.

Dieses Verfahren erfordert das vollständige Scannen des zu stützenden Körperteils. Aus diesen Messdaten werden dann Maschenreihe für Maschenreihe die erforderliche Maschenzahl und/oder Spickelpunkte für die optimale Passform des Kompressionsartikels berechnet. Eine Maschenzunahme oder eine Maschenminderung kann an jeder Stelle innerhalb einer Maschenreihe erfolgen, nicht nur an den Rändern von Teilabschnitten. Dieses aufwändigere Verfahren eignet sich insbesondere zur Herstellung von Kompressionsartikeln für Patienten mit Beschwerden, für die eine hervorragende Passform und eine optimale Kompressionsdruckverteilung unerlässlich sind.This procedure requires complete scanning of the body part to be supported. From these measured data, the required mesh count and / or winding points for the optimum fit of the compression article are then calculated in stitch row for stitch course. Mesh increase or decrease can be done anywhere within a course, not just at the edges of sections. This more elaborate process is particularly suitable for the production of compression articles for patients with discomfort, for which an excellent fit and an optimal compression pressure distribution are essential.

Im Folgenden wird ein bevorzugtes Ausführungsbeispiel eines erfindungsgemäßen Kompressionsartikels mit Bezug auf die Zeichnung näher beschrieben.In the following, a preferred embodiment of a compression article according to the invention will be described in more detail with reference to the drawing.

Die vier Teilabschnitte 11 bis 14 werden dabei mit gemeinsamen Fadenführern gestrickt, sodass sich das in Fig. 2 gezeigte, fertige Gestrick ergibt. Die Darstellung in Fig. 1 dient jedoch der besseren Erläuterung des Herstellungsverfahrens des Artikels 10.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.

Jedes der Teilabschnitte 11 bis 14 wird in den Zonen 15 bis 18 an den Längsrändern der Teilabschnitte 11 bis 14 bezüglich der Maschenzahl in jeder Maschenreihe derart angepasst, dass das fertige Kompressionsgestrick 10 in seiner Form einem zu stützenden Körperteil optimal angepasst ist. Dazu werden Messdaten des Körperteils zunächst dazu verwendet, einen Grundschnitt für den Kompressionsartikel 10 aus einem Set verfügbarer Schnitte auszuwählen, der bereits nahe an der erforderlichen Form des Kompressionsartikels 10 liegt. Die Schnitte der Teilabschnitte 11 bis 14 dieses Grundschnitts werden anschließend so korrigiert, dass die Passform des aus den Teilabschnitten zusammengesetzten Kompressionsartikels 10 der Form des Körperteils optimal angepasst ist. Diese Korrektur geschieht durch Anpassen der Maschenzahl je Maschenreihe in den Zonen 15 bis 18 an den Längsrändern der Teilabschnitte 11 bis 14 sowie dem Vorsehen von Spickelzonen 19 zumindest in einigen der Teilabschnitte 11 bis 14. Auch die Länge der Maschenstäbchen der Teilabschnitte 11 bis 14 wird entsprechend der Körperteilform variiert. Insgesamt entsteht somit der in Fig. 2 gezeigte dreidimensionale Kompressionsartikel 10, der nur noch durch eine Längsnaht geschlossen werden muss.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. For this purpose, 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. This correction is done by adjusting the number of stitches per row of stitches in the zones 15 to 18 at the longitudinal edges of the sections 11 to 14 and the provision of Spickelzonen 19 at least in some of the sections 11 to 14. The length of the wales of the sections 11 to 14 is accordingly the body part shape varies. Altogether thus the in Fig. 2 shown three-dimensional compression article 10, which only has to be closed by a longitudinal seam.
