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, in which the number of stitches per row of stitches is adapted to the radial circumference of the part of the body 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. Entsprechende Beispiele sind in den Dokumenten DE 10 2015 115228 B3 , EP 1 621 164 A1 , WO 03/040449 A1 , US 4 527 402 A und EP 2 848 235 A1 beschrieben.Such compression articles in the form of compression stockings, compression gloves, foot caps and the like are used in particular to prevent or treat edema, varicose veins, venous insufficiency and after venous surgery. Corresponding examples are in the documents DE 10 2015 115228 B3 , EP 1 621 164 A1 , WO 03/040449 A1 , U.S. 4,527,402 A and EP 2 848 235 A1 described.

Weitere elastische Artikel sind Gelenkbandagen oder auch Verbrennungsbandagen. Im Sport werden stützende Bandagen zum Schutz vor Verletzungen und teilweise auch zur Leistungserhöhung eingesetzt.Other elastic items are joint bandages or burn bandages. Supportive bandages are used in sports to protect against injuries 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.Due to the good elastic properties, these articles are mainly produced as knitted fabrics, with production on a flat knitting machine being the norm. The article is produced as a flat knitted fabric, the longitudinal edges of which are then sewn together, resulting in the desired three-dimensional article. The flat-lying knitted fabric is knitted with more stitches per row in areas in which the body part to be treated has a larger circumference than in areas with a 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-lying knitted fabric, this longitudinal seam has a curved course, while the opposite circumferential area of the compression article runs absolutely straight in the longitudinal direction. The shape of the compression article thus imitates the anatomy of the body part only imperfectly. 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. Der Erfindung liegt daher die Aufgabe zugrunde, Kompressionsartikel mit einer verbesserten Passform zur Verfügung zu stellen.However, in patients, bulging and changes in shape of the affected part of the body are possible at all points of the circumference. A lower leg of such a patient can therefore not only show the muscle-related increase in circumference in the calf area, but also bulges in the shin area. Therefore, the compression articles that have been available up to now do not fit sufficiently even if the body part is accurately measured and the compression article is custom-made. In addition, the flat knitting technology used today and described above is only suitable to a limited extent for the manufacture of such products. The object of the invention is therefore to provide compression articles with an improved fit.

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, wobei der Kompressionsartikel ein Kompressionsstrumpf 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 object is achieved by a compression article produced on a knitting machine, in particular a flat knitting machine knitted fabric produced, in which the number of stitches per row of stitches is adapted to the radial circumference of the part of the body to be treated by the compression article, the compression article being a compression stocking, and which is characterized in that it has several in the circumferential direction in order to adapt to the shape of the part of the body to be treated has points distributed over its circumference at which stitches increase and/or decrease stitches in a row of stitches, and that the number of stitches in the direction of the wales 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 part is.

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 stitch increases and/or stitch reductions occur at those circumferential points at which the body part to be supported also experiences a change in circumference and no longer only in the area of the longitudinal seam of the article. In addition, the fit in the longitudinal direction is improved by also varying the number of stitches in the wale direction of the compression article over its circumference. For example, a compression stocking according to the invention can have more rows of stitches in the calf area than in the shin area. This allows not only a better fit of the compression article, but also a more even distribution of the compression pressure on the body part. The three-dimensional knitted article therefore has improved effectiveness in addition to improved fit.

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.The compression article can preferably be knitted in such a way that its central longitudinal axis coincides with the central longitudinal axis of the body part to be treated. 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.It is also advantageous if the compression article is produced as a three-dimensional flat or circular knitted fabric. A three-dimensional structure is created by stitch accumulations in a central area of the knitted fabric. However, the compression article can also be produced as a seamless tubular-round knitted fabric and thus obtain a three-dimensional shape. The step of subsequently sewing the edges of the knitted fabric together 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 made using spiking techniques. Almost any three-dimensional structure can be produced with lacing techniques in connection with the stitch increase and/or stitch decrease distributed over the circumference.

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 can be formed from a plurality of strip-shaped partial sections which are separated from one another in the circumferential direction of the compression article by zones with increased and/or decreased stitches.

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 folglich auch nicht parallel zueinander verlaufen.Depending on the number of sections, compression articles can thus be produced in a technically relatively simple manner, in which there is an increase in the stitches and/or a reduction in the stitches at a number of circumferential locations. Consequently, the side edges of the partial sections cannot run parallel to one another.

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. 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.In addition, at least some of the sections can have a different number of rows of stitches or a different length of wales (=number of stitches per wale) in order to be able to adapt the compression article well to the contour of the body part in its longitudinal direction. Preferably, the division of the knitted fabric into sections, the number of stitches per row of stitches in the sections and the number of rows of stitches per section can be determined accordingly from data obtained when measuring the part of the body to be supported.

Der Kompressionsartikel wird außerdem in an sich bekannter Weise zumindest teilweise unter Verwendung von elastischen Garnen hergestellt .The compression article is also produced in a manner known per se, at least partially using elastic yarns.

Die elastischen Fäden können dabei die Grundbindung des Artikels bilden und/oder als Schuss- und/oder Kettfäden eingebunden sein.The elastic threads can form the basic weave of the article and/or be integrated 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, additional benefits accrue as the compressive pressure applied to the body part by the compression article decreases from the article's distal end to the proximal end. This measure supports the draining of lymphatic fluid towards the heart and thus promotes the elimination 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 from a double faced or double layered knit. For example, the knit may be made of an R-R weave. Or it can have several R-L layers that are connected to one another over a large area or at points.

Die Erfindung betrifft außerdem ein erstes Verfahren zur Herstellung eines Kompressionstrumpfes auf einer Strickmaschine, insbesondere einer Flachstrickmaschine, mit den folgenden Schritten:

  • 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 in Umfangs- und Körperteillängsrichtung zwischen den Messpunkten, wobei der korrigierte Grundschnitt durch Berechnen mehrerer längs verlaufender, den Kompressionsartikel (10) bildende, Teilabschnitte hergestellt wird, wobei die Teilabschnitte (11 bis 14) in Umfangsrichtung des Kompressionsartikels (10) jeweils durch Zonen (15 bis an ihren Längsrändern, in denen die Maschenzahl der Maschenreihen des Gestricks (10) vermindert und/oder vergrößert wird, voneinander getrennt sind und wobei zumindest einige der Teilabschnitte eine unterschiedliche Anzahl von Maschenreihen aufweisen;
  • Stricken des korrigierten Grundschnittes auf einer Strickmaschine, insbesondere einer Flachstrickmaschine.
The invention also relates to a first method for producing a compression stocking on a knitting machine, in particular a flat knitting machine, with the following steps:
  • measuring the body part to be supported by the compression article at individual measuring points;
  • selecting from a catalog a baseline compression article fit whose measurements best match the measured body part;
  • Correction of the number of stitches of the rows and the number of stitches in the individual wales of the basic pattern according to the dimensions of the body part in the circumferential and longitudinal direction of the body part between the measuring points, the corrected basic pattern being produced by calculating a plurality of longitudinal sections forming the compression article (10). , wherein the sub-sections (11 to 14) are separated from one another in the circumferential direction of the compression article (10) by zones (15 to at their longitudinal edges, in which the number of stitches of the rows of stitches of the knitted fabric (10) is reduced and/or increased, and wherein at least some of the sections have a different number of courses;
  • Knitting the corrected basic pattern on a knitting machine, in particular a flat knitting machine.

Dieses Verfahren eignet sich insbesondere zur Herstellung von Kompressionsartikeln mit sehr guter Passform.This method is particularly suitable for the production of compression articles with a very good fit.

Anzahl der Teilabschnitte kann vorgegeben sein oder frei gewählt werden.The number of sections can be specified or freely selected.

Ein alternatives Verfahren zur Herstellung eines Kompressionsstrumpfes auf einer Strickmaschine, insbesondere einer Flachstrickmaschine nach der Erfindung umfasst die folgenden 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, über den Umfang des Kompressionsartikels verteilten, Stellen innerhalb jeder Maschenreihe, an denen eine Maschenzu- und/oder -abnahme im Vergleich zur vorangehenden Maschenreihe erforderlich ist, sodass im angezogenen Zustand des Kompressionsartikels 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 stocking on a knitting machine, in particular a flat knitting machine, according to the invention comprises the following 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 row of stitches according to the measured circumference of the body part in the area of the body part covered by the row of stitches;
  • Calculation of those places distributed over the circumference of the compression article within each row of stitches at which a stitch increase and/or decrease compared to the preceding row of stitches is required so that in the tightened state of the compression article the central longitudinal axis of the compression knitted fabric 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 the compression article on a flat knitting machine using the calculated counts of stitches per course, the calculated places of increase and/or decrease in the courses, and the calculated necessary numbers 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 full scanning of the body part to be supported. The required number of stitches and/or gusset points for the optimal fit of the compression article are then calculated from this measurement data, stitch row by stitch row. A stitch increase or decrease in stitches can occur anywhere within a row of stitches, not just at the edges of sections. This more complex process is particularly suitable for the production of compression articles for patients with complaints, for whom an excellent fit and optimal compression pressure distribution are essential.

Im Folgenden wird ein bevorzugtes Ausführungsbeispiel eines erfindungsgemäßen Kompressionsartikels mit Bezug auf die Zeichnung näher beschrieben.A preferred exemplary embodiment of a compression article according to the invention is described in more detail below with reference to the drawing.

Der in den Fig. 1 und 2 gezeigte Kompressionsartikel 10 wird im dargestellten Beispiel auf einer Flachstrickmaschine hergestellt und im Entwurfsstadium in vier Teilabschnitte 11, 12, 13 und 14 aufgeteilt, die zwischen sich Zonen 15 - 18 definieren, in denen eine Maschenzunahme und/oder eine Maschenminderung erfolgt. 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 1 and 2 The compression article 10 shown is produced on a flat knitting machine in the example shown and divided into four subsections 11, 12, 13 and 14 at the design stage, which define zones 15-18 between them, in which a stitch increase and/or a stitch reduction takes place. The four sections 11 to 14 are knitted with common thread guides, so that the 2 finished knitted fabric shown. The representation in 1 however, serves to better explain the manufacturing process of Article 10.

Jeder 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. Somit wird auch die Länge der Maschenstäbchen der Teilabschnitte 11 bis 14 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 adjusted in the zones 15 to 18 on the longitudinal edges of the sections 11 to 14 with respect to the number of stitches in each row of stitches such that the finished compression knitted 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 pattern for the compression article 10 from a set of available patterns, which is already close to the required shape of the compression article 10 . The cuts of the partial sections 11 to 14 of this basic pattern are then corrected in such a way that the fit of the compression article 10 composed of the partial sections is optimally adapted to the shape of the body part. This correction is done by adjusting the number of stitches per row of stitches in zones 15 to 18 on the longitudinal edges of sections 11 to 14 and the provision of gusset zones 19 at least in some of sections 11 to 14. This also reduces the length of the wales in sections 11 to 14 varies according to body part shape. Overall, the in 2 shown three-dimensional compression article 10, which only has to be closed by a longitudinal seam.
