Description

The invention relates to a medical knitted part, in particular in the form of an orthopedic bandage or a bandage, for resting on a body part of a patient for medical or therapeutic treatment or for supporting the body part, according to the preamble of claim 1. The medical knitted part according to the invention can in particular have the form of a tubular bandage, a stocking or sock, or a glove.

From the EP 2 268 245 B1 an orthopedic aid designed as a compressive knitted part is known in the form of a bandage, orthosis, splint or support, or a compressive clothing or knitted part for therapy or support of body parts with a functional element with an additional therapeutic effect, the functional element being introduced into a receiving device which adjoins an opening worked into the knitted part, which serves as access to the receiving device, the opening being worked into the knitted part in the knitting process as a slit formed in the transverse direction of the knitted fabric (i.e. running in the course of the course). The course of the opening in the transverse direction is intended to prevent the compression course of the compressive knitted part from being interrupted by the opening. The receiving device can in particular be designed as a pocket which is sewn, welded or glued onto the knitted part. The functional element with an additional therapeutic effect can in particular be a pad or an elastic molded body or a solid body. The functional element can have a therapeutic effect, such as an additional compression pressure, or other therapeutic effects, such as a temperature-regulating effect or a medical effect on the part of the body to which the orthopedic aid is applied.

The use of such functional elements, for example in the form of (partially) elastic pads, is known in the field of compression therapy in connection with compression articles such as compression gloves or compression bandages, for example in order to exert additional compression pressure on a part of the body to be treated, over the Compression pressure exerted evenly over a large area by the compression part goes out.

In some applications it is difficult to introduce the functional element into the receiving device through an opening running in the transverse direction of the knitted fabric, for example when the functional element has a curved shape.
Proceeding from this, the invention is based on the object of providing a simple, quick and inexpensive to manufacture knitted part for medical applications, which has a pocket into which a functional element can be inserted without hindrance, which has a therapeutic effect on a part of the body on which the medical knitted part is created, can exercise. The opening provided as access to the pocket should influence a compressive effect of the knitted part as little as possible, and it should also be possible to introduce curved functional elements into the pocket without hindrance.

This object is achieved with a medical knitted part having the features of claim 1. Preferred embodiments and applications of the medical knitted part according to the invention emerge from the dependent claims.
The medical knitted part according to the invention can for example be in the form of an orthopedic bandage or a bandage for contact with a body part of a patient for medical or therapeutic treatment or for supporting the body part, wherein the knitted part is a basic knitted fabric knitted in one direction and at least one pocket for receiving at least one functional element as well as a slot-shaped opening worked into the basic knitted fabric, through which the functional element can be introduced into the pocket and / or removed from the pocket. The knitted part according to the invention is knitted on a flat knitting machine, the opening being knitted seamlessly into the basic knitted fabric and running at an angle to the knitting direction.

According to the invention, in the knitting process on the flat knitting machine when knitting the basic knitted fabric, the opening is knitted into the basic knitted fabric in such a way that the slot-shaped opening extends in a slot direction which runs obliquely to the knitting direction. The slit direction of the opening preferably forms an angle of 30 ° to 60 ° and in particular 45 ° with the knitting direction. The knitting direction corresponds to the wale direction of the knitted fabric.

The medical knitted part according to the invention can in particular have the shape of a tubular bandage, a stocking or sock, or a glove.

To form a tubular knitted part, the basic knitted fabric knitted as a flat knitted fabric on a flat knitting machine is formed into a tube and two end edges of the basic knitted fabric are sewn together along a seam in order to fix the tube. The bag is attached to the before or after the tube is formed Basic knitted fabric attached, for example by sewing, gluing or welding. The pocket is expediently designed in the shape of a sack or hose. The bag can be knitted as a circular knitting on a circular knitting machine or on a flat knitting machine.

At least one medically or therapeutically effective functional element can be introduced into the pocket, which is expediently designed as a sack or tube open on one side with the open side facing the opening in the basic knitted fabric. The functional element can be, for example, a pressure body, a cushioned body, an inelastic or elastic molded body and in particular a pad. When the knitted part rests on a part of the body of a patient, the functional element exerts a therapeutic or medical effect on the body part, for example a pressure and / or temperature effect and / or a cushioning effect and / or an administration of a medically or therapeutically active substance to the body part . For the administration of a medically or therapeutically active substance to the body part, the functional element can be impregnated with a medically or therapeutically active substance, for example, which is released to the body part when the knitted part according to the invention with a corresponding functional element has been introduced into the pocket provided for it is, rests on the body part of the patient so that the substance stored in the functional element can diffuse through the knitted fabric of the bag into the body part. The functional element is expediently designed as a retard, which releases the drug more slowly.

The basic knitted fabric can in particular be designed as a right / left knitted fabric or preferably as a right / right knitted fabric. The basic knitted fabric from which a basic body of the medical knitted part according to the invention is made can expediently be a stretchable knitted fabric and in particular a compression knitted fabric. This has the effect that the medical knitted part exerts a uniform basic pressure on the body part over the entire surface when it comes into contact with a body part of a patient. When a functional element in the form of a pressure body or a pad is introduced into the pocket of the knitted part according to the invention provided for this purpose, the basic pressure exerted by the basic body of the knitted part on the body part can be increased in areas or at certain points in the area in which the functional element is in contact with the patient's body part is located.

The basic knitted fabric can in particular be knitted from an (elastic or inelastic) knitting thread and has rows of stitches formed from the knitting thread and running perpendicular to the knitting direction. To form the basic knitted fabric as a compression knitted fabric, an elastic, stitch-forming knitting thread can be used when knitting the basic knitted fabric and / or an elastic weft thread can be tied into the basic knitted fabric or inserted under tension. A high compression effect can be achieved if a weft thread runs between each row of stitches in the basic knitted fabric.
The at least one opening can be knitted into the basic knitted fabric at predetermined transfer points in a manner that is very efficient in terms of knitting technology by transferring stitches of the basic knitted fabric from a row of stitches into the stitches that follow in the knitting direction (wale direction). In order to produce the oblique course of the slot-shaped opening, the hanging points are arranged offset from one another by at least one stitch in successive courses in the course of the course. The direction of the displacement of the transfer points in successive rows of stitches is expediently the same in each case. As a result, a uniform course of the slit direction at an angle to the knitting direction can be achieved. For this purpose, the number of stitches by which the transfer points are offset from one another in successive courses of stitches is also preferably the same in all courses of stitches. This results in a straight course of the edges of the slot-shaped opening.

• • Stricken eines ersten (mittleren) Teilstücks mit einer in Strickrichtung aufeinanderfolgenden Anzahl von Maschenreihen entsprechend der gewünschten Ausdehnung der Öffnung in Stickrichtung, wobei die Anzahl der Maschen in aufeinanderfolgenden Maschenreihen vermindert wird, wodurch in dem ersten (mittleren) Teilstück nicht verstrickte Maschen auf den Nadeln des vorderen Nadelbetts und des hinteren Nadelbetts hängen bleiben,
• • Stricken eines zweiten (rechten) Teilstücks mit einer in Strickrichtung aufeinanderfolgenden Anzahl von Maschenreihen entsprechend der gewünschten Ausdehnung der Öffnung in Stickrichtung, wobei die Anzahl der Maschen in aufeinanderfolgenden Maschenreihen erhöht wird und dabei das zweite (rechte) Teilstück aufgrund der nicht verwendeten und noch in den Nadeln des Nadelbetts hängenden Maschen des Mittelstücks (rechts) neben dem ersten (mittleren) Teilstück zu liegen kommt und sich zwischen dem ersten (mittleren) Teilstück und dem zweiten (rechten) Teilstück ein sich schräg zur Strickrichtung erstreckender Schlitz ausbildet, der die Öffnung bildet.

To produce the knitted part according to the invention, the basic knitted fabric is knitted on a flat knitting machine with a front needle bed and a rear needle bed with rows of stitches formed from a knitting thread running perpendicular to the knitting direction, and for knitting the opening running obliquely to the knitting direction, first in the knitting direction and over the entire width of the Basic knit several consecutive courses of the basic knit are knitted, with the following knitting sequence taking place at a point where an opening is to be created:

• • Knitting a first (middle) section with a number of courses following one another in the knitting direction according to the desired size of the opening in the embroidery direction, whereby the number of stitches in consecutive courses is reduced, as a result of which stitches on the needles that are not knitted in the first (middle) section the front needle bed and the rear needle bed get caught,
• • Knitting a second (right) section with a number of rows of stitches following one another in the knitting direction according to the desired size of the opening in the embroidery direction, the number of stitches in successive rows of stitches is increased and the second (right) section comes to lie next to the first (middle) section and is between the first (middle) section and due to the unused stitches in the center piece (right) still hanging in the needles of the needle bed the second (right) section forms a slit which extends obliquely to the knitting direction and which forms the opening.

In a corresponding manner, after the second (right) section has been knitted, a third (left) section can optionally be knitted, which is knitted with the stitches still in the left part on the needles of the needle bed and thus (left) next to the first (middle) ) Part comes to rest. When knitting the third (left) section, the number of stitches (number of stitches in successive rows of stitches) can be reduced or increased, depending on the desired direction of the inclination of the slot. A slot which extends obliquely to the knitting direction and which forms a further opening is also formed between the first (middle) section and the third (left) section. The order of the sections (i.e. first, second and third sections) or the right and left sides can also be swapped.

In this way, several slot-shaped openings can be knitted into the basic knitted fabric, the openings each extending at an angle to the knitting direction. The inclination of the openings (slot direction) can be the same or different, i.e. the slot-shaped openings can run parallel to one another at a distance from one another or enclose an angle with one another which can be between 10 ° and 170 ° and preferably in the range from ± 30 ° to ± 60 °.

The knitting of two opposing openings can be advantageous, for example, when a longer, rod-shaped or a crescent-shaped or saber-shaped functional element is to be introduced into a pocket of the knitted part that is open on both sides. The two open sides of the pocket are each connected to an opening for introducing or removing a functional element. The or each slot extends in a slot direction which preferably forms an angle with the knitting direction in the range from ± 10 ° to ± 80 ° and particularly preferably in the range from ± 30 ° to ± 60 °. The direction and / or the sign of the inclination of the slots can be the same or different.

To close the upper ends (viewed in the knitting direction) of the respective opening, after the right part and possibly the left part have been knitted, further rows of stitches can be knitted from the knitting thread over the entire width of the basic knit in the knitting direction. As a result, the ends of the or each opening are already fixed in the knitting process without subsequent chaining or sewing, whereby fraying of the opening, in particular at its ends, can be prevented.

The pocket, which is used to hold the functional element, is expediently knitted from a pocket knitted fabric in a separate knitting process on a circular or flat knitting machine, wherein the knitted fabric of the pocket knitted fabric can at least essentially correspond to the knitted fabric of the basic knitted fabric. The pocket knitted fabric can be knitted, for example, as a right / right knitted fabric or as a right / left knitted fabric from an elastic or inelastic and stitch-forming knitting thread.

Preferably no weft thread is contained in the pocket knitted fabric. This ensures easier introduction of the functional element into the pocket. However, it is also possible to insert an elastic weft thread into the knitted pocket, which pulls the knitted pocket and thus the pocket together in the transverse direction (that is, transversely to the wale direction or in the circumferential direction of the tubular pocket). When using a weft thread in the pocket knitted fabric, a resistance caused by the compressive effect of the weft thread must be overcome when the functional element is inserted into the pocket in order to be able to push the functional element completely into the pocket. However, due to the compressive effect of the elastic weft thread, the functional element introduced into the pocket is fixed in the pocket due to the compression pressure generated by the weft thread. This prevents the functional element from slipping in the pocket.

To prevent the functional element from accidentally emerging from the pocket, it is also possible to close the opening of the pocket by means of a seam after the functional element has been introduced. The seam can expediently also be separated again in order to be able to remove the functional element from the pocket. This enables a functional element to be replaced by another, therapeutically or medically effective functional element.

In 1 shows a first embodiment of a medical knitted part according to the invention in the form of a wrist bandage. The wrist bandage has a basic body made of a basic knitted fabric 1 with an opening knitted into it 2 and a pocket on the inside (which faces the patient's forearm when the bandage is applied) 3 for receiving a functional element 4th on. The ones in the basic knit 1 knitted opening 2 is slit-shaped and runs obliquely to the knitting direction s. The slit-shaped opening 2 thus has a slot direction (longitudinal direction of the slot) which is inclined (here at an angle of approximately 45 °) to the knitting direction s. Through the opening 2 can an in 1 Functional element indicated by dashed lines 4th in the pocket 3 brought in and out of the pocket again 3 be taken out. Due to the inclination of the slot-shaped opening 2 in relation to the knitting direction s, which corresponds to the longitudinal direction of the bandage, the insertion and removal of the functional element 4th facilitated.

With the functional element 4th it can, for example, be a pressure or cushion body, in particular a pad. In the in 1 The functional position of the glove shown, the pad rests on the forearm of a patient (with the knitted pocket fabric of the sack-shaped bag between the forearm and the pad 3 and thereby exercises in the area of the pocket 3 additional pressure beyond the pressure exerted evenly on the forearm by the bandage. That in my pocket 3 introduced functional element 4th acts as a pressure body.

Instead of a pressure body designed as a pad, an easily deformable cushioned body, for example made of a foam, or some other medically or therapeutically effective functional element can also be used 4th in the pocket 3 be introduced. In any case, practice it in your pocket 3 introduced functional element 4th a therapeutic or medical effect on the part of the body on which the knitted part according to the invention is applied.

The opening 2 be closed by a seam. Closing the opening 2 a seam takes place after inserting the functional element 4th in the pocket 3 . The seam prevents that from getting into the pocket 3 inserted functional element 4th when carrying the knitted part out of the pocket 3 can slip out unintentionally.

For the production of the basic body 1 of the knitted part according to the invention, such as the one in 1 The bandage shown is the basic knit 1 of the base body as a flat knitted fabric on a flat knitting machine with a front needle bed and a rear needle bed opposite this.

To form a tubular knitted part, the basic knitted fabric is knitted as a flat knitted fabric 1 first formed into a tube and two opposite end edges of the basic knitted fabric are sewn together along a seam in order to fix the tube. The pocket 3 is attached to the base fabric over the opening before or after the tube is formed 2 attached, for example by sewing, gluing or welding. The pocket 3 is expediently sack-shaped or tubular with at least one open side. The pocket 3 is done like this on the basic knitted fabric 1 attached to that one open side of the bag 3 with one in the basic knit 1 knitted opening 2 is connected. The opening 2 serves as access to the (one or two-sided) open pocket 3 through which a functional element 4th in the pocket 3 insertable (or removable from the pocket).

The pocket 3 is appropriately knitted in a separate knitting process as a tubular or sack-shaped body from a pocket knitted fabric, for example as a circular knitted fabric on a circular knitting machine or a flat knitting machine. The pocket knitted fabric preferably has a knitted fabric that is at least essentially the same as the knitted fabric of the basic knitted fabric 1 corresponds. The basic knit 1 and thus expediently also the pocket knitted fabric can for example be designed as a right / left or preferably as a right / right knitted fabric.

For training the basic knit 1 of the basic body as a compression knitted fabric can be provided that in the basic knitted fabric 1 an elastic weft thread is involved. In contrast, the pocket knitted fabric preferably has no weft thread.

• Beim Stricken des Grundgestricks 1 wird ein Strickfaden 6 in einem Rechts-Rechts-Gestrick (R-R) maschenbildend verstrickt, wodurch sich Maschenreihen m, m+1, usw. ausbilden, die sich in Strickrichtung s fortsetzen. Eine RR-Maschenreihe zeichnet sich dabei dadurch aus, dass im Wechsel auf dem vorderen und hinteren Nadelbett eine Masche gebildet wird. Somit ergibt sich bei jeder Masche eine Verbindung zwischen dem vorderen und hinteren Nadelbett. Um eine Kompressionswirkung zu erzeugen, kann in das Grundgestrick 1 ein elastischer Schussfaden eingebracht werden. In dem zeichnerisch dargestellten Strickbild der 5 ist zwischen in Strickrichtung s aufeinanderfolgenden Maschenreihen m, m+1 jeweils ein Schussfaden 7 eingebracht. In dem Strickbild der 5 wechseln sich also Maschenreihen m des Strickfadens 6 mit Schussreihen des Schussfaden 7 ab. Dadurch wird ein flächiges Gestrick erzeugt, welches sich in Querrichtung (also senkrecht zur Strickrichtung s) über eine vorgegebene Breite erstreckt. Dieser (untere) Bereich des Grundgestricks 1 ist in den 2 und 3 mit „u“ bezeichnet.

Referring to the drawings, FIG 2 and 3 knitting the opening 2 in the basic knit 1 when knitting the basic knit 1 explained in more detail on a flat knitting machine with a front and a rear needle bed, the basic knitted fabric in the example shown 1 is designed as a right / right knit:

• When knitting the basic knit 1 becomes a knitting thread 6th knitted in a right-to-right knitted fabric (RR) to form loops, as a result of which courses m, m + 1, etc. are formed which continue in knitting direction s. An RR stitch row is characterized by the fact that a stitch is formed alternately on the front and rear needle bed. This results in a connection between the front and rear needle beds for each stitch. In order to create a compression effect, the basic knit can be used 1 an elastic weft thread can be introduced. In the graphically illustrated knitting picture of 5 there is a weft thread between each row of stitches m, m + 1 following one another in knitting direction s 7th brought in. In the knitting picture of the 5 So alternate rows of stitches m of the knitting thread 6th with weft rows of the weft thread 7th from. This creates a flat knitted fabric which extends in the transverse direction (i.e. perpendicular to the knitting direction s) over a predetermined width. This (lower) area of the basic knit 1 is in the 2 and 3 marked with "u".

At one point where an opening 2 should arise (in 3 From row m + 2), proceed as follows: First, in the same way as in the lower area u of the basic knit 1 a first (right) section R is knitted, with the number of stitches m + 2, m + 3, etc. successive in knitting direction s being reduced to form the inclined position of the opening. Preferably, the number of stitches is reduced by one stitch in each row of stitches following one another in the knitting direction s. In order to reduce stitches in the first section R, the outermost stitches must be hung further inwards. This is in the knitting picture 3 represented by the shoulder arrows U. In the present illustration, the outermost right stitch of the front needle bed is transferred to the second stitch from the right of the rear needle bed and the outermost right stitch of the rear needle bed is transferred to the now outermost right stitch of the front needle bed. This is repeated in every course m + 2, m + 3, m + 4 etc. until a top course m + x is reached, where the opening is 2 should end ( 3 ).

A second (left) section L is then knitted in a corresponding manner, the number of stitches being increased in successive courses (preferably by one stitch each). In the knitting variant shown, the number of stitches in the second section L is increased by simply knitting a stitch onto the front needle bed. Since in the following row of stitches m + 3 or m + 4, etc., an RR row is knitted at this point, the result is a continuous stitch structure. The weft rows of the weft thread 7th are simply transferred to the next row by continuing the weft thread guide in successive rows.

In the knitting picture of the 3 it looks as if the second section L is above the first section R. Since the stitches of the lower section u of the basic knit 1 that were not used in the first section R but are still hanging on the needles in the needle bed, the second section L comes “down” and is ultimately (left) next to the first section R. Thereby between the first section R and the second section L a slit extending obliquely to the knitting direction, which forms the opening 2 forms.

Around the slot-shaped openings 2 To close at its upper end, another area in the form of an upper part o is knitted over the entire width of the basic knitted fabric, corresponding to the lower part u of the basic knitted fabric 1 (with a row of shots and a row of RRs alternating).

In 4th an enlarged schematic representation of a further knitted fabric for a knitted part according to the invention with two openings for introducing functional elements is shown. Based on the animated picture of 5 will be knitting the two openings 2 , 2 ' explained: As in the embodiment of 3 is also used here when knitting the basic knit 1 a knitting thread 6th knitted in a right-to-right knitted fabric (RR) to form loops, as a result of which courses m, m + 1, etc. are formed which continue in knitting direction s. In the illustrated knitting picture the 5 is likewise a weft thread in each case between rows of stitches m, m + 1, m + 2, etc., which follow one another in the knitting direction s 7th brought in. In the knitting picture of the 5 So alternate rows of stitches m of the knitting thread 6th with weft rows of the weft thread 7th from. As a result, a flat knitted fabric is produced which extends in the transverse direction (that is, perpendicular to the knitting direction s) over a predetermined width. This (lower) area of the basic knit 1 is in 4th marked with "u".

At one point where the two openings 2 , 2 ' should arise (in the example of the 5 From row m + 2), proceed as follows: First, in the same way as in the lower area u of the basic knit 1 a first, middle section M (middle piece) is knitted, whereby the number of stitches m + 2, m + 3, etc. successive in knitting direction s is reduced to form the inclined position of the opening. The number of stitches is preferably reduced by one stitch in each case from stitch row m to stitch row m + 1. In order to reduce stitches in the first, middle section M, the outermost stitches must be hung further inwards. This is in the knitting picture 5 represented by the shoulder arrows U. In the present illustration, the outermost right stitch of the front needle bed is transferred to the second stitch from the right of the rear needle bed and the outermost right stitch of the rear needle bed is transferred to the now outermost right stitch of the front needle bed. This is repeated in every course m + 2, m + 3, m + 4, etc. until a top course m + x is reached, where the openings are 2 , 2 ' should end ( 5 ).

A second, right-hand section R is then knitted in a corresponding manner, with the number of stitches in successive courses of stitches m + 2, m + 3, etc. being expanded (preferably by one stitch each). In the knitting variant shown, the number of stitches in the right section R is increased by simply knitting a stitch onto the front needle bed. Since in the following row of stitches m + 3 or m + 4, etc., an RR row is knitted at this point, the result is a continuous stitch structure. The weft rows of the weft thread 7th are in turn simply taken over into the next row by continuing the weft thread guide in successive rows.

In the knitting picture of the 5 it looks as if the second, right-hand section R is above the first, middle section M. Since the stitches of the lower part u of the basic knit, which were not used in the first, middle part M, but are still hanging on the needles in the needle bed, the second, right part R comes "down" and is ultimately to the right of the first, middle section M. In this case, between the first, middle section M and the second, right section R, a slit which extends obliquely to the direction of knitting and which forms the first opening 2 forms.

In the in the 4th and 5 example shown is in addition to the first opening 2 another opening 2 ' in the basic knit 1 knitted in accordingly. For this purpose, a third, left-hand section L is knitted in the same way on the left side of the first, middle section M by increasing the number of stitches in rows m + 2, m + 3, etc. (preferably in each case by one stitch).

The stitches of the third, left section L are knitted on the stitches in the left part that are still on the needles of the needle bed, so that the third, left section L comes to lie to the left of the first, middle section M. This results in a basic knitted fabric with two slot-shaped openings 2 , 2 ' which are initially open at the top (o). Around the slot-shaped openings 2 , 2 ' To close at its upper end, another area in the form of an upper part o is knitted over the entire width of the basic knitted fabric, corresponding to the lower part u of the basic knitted fabric 1 (with a row of shots and a row of RRs alternating).

The openings knitted into the basic knit in this way 2 , 2 ' run at a given angle of approx. 45 ° to the knitting direction. The angle can be set by the number of stitches added in the right or left section R, L and the meshes that are correspondingly reduced in the middle section M. This allows inclined openings 2 , 2 ' with different directions and different angles of inclination in the basic knitted fabric 1 knit in. The angle between the knitting direction s and the slit direction (longitudinal direction of the slit 2 , or. 2 ' ) is expediently between ± 10 ° to ± 80 °, preferably between ± 30 ° to ± 60 °. In 6th is another embodiment of one medical knitted part according to the invention shown in the form of a knee joint bandage in which in the above-described and in 4th manner shown two opposite openings 2 , 2 ' in the basic knit 1 have been knitted in.

The knee joint bandage in turn has a base body made of a basic knitted fabric 1 with the two openings knitted into it 2 , 2 ' and a pocket on the inside (facing the patient's knee when the bandage is applied) 3 for receiving a functional element 4th on. The ones in the basic knit 1 knitted openings 2 , 2 ' are slit-shaped with a slit direction (longitudinal direction of the slot) which is inclined (here at an angle of approx. 45 ° or 315 °) to the knitting direction s. The slot directions of the two openings 2 , 2 ' are at an angle of approx. 90 ° to each other. On the inside of the knee bandage is a tubular pocket that is open on both sides 3 arranged, the open ends of which each with one of the two openings 2 , 2 ' keep in touch. Through the openings 2 , 2 ' can an in 3 Functional element indicated by dashed lines 4th in the pocket 3 brought in and out of the pocket again 3 be taken out. Due to the inclination of the slot-shaped openings 2 , 2 ' in relation to the knitting direction s, which corresponds to the longitudinal direction of the bandage, the insertion and removal of the functional element 4th facilitated. The two ends of the ring-shaped curved functional element 4th stand out how 6th can be seen from the openings 2 , 2 ' out and can be outside of the pocket 3 , for example with a hook or Velcro fastener, can be fixed to one another.

In the 7th and 8th is a schematic representation of a further knitted fabric for a knitted part according to the invention with two openings running parallel and at a distance from one another 2 , 2 ' shown for the introduction of functional elements. From the knitting picture of 8th is the knitting of the two openings 2 , 2 ' corresponding to the embodiment of 5 in the manner described, whereby after knitting the lower part u, first the knitting of the right part R, then the middle part M and finally the left part L are knitted. Finally, the upper part is knitted over the entire width of the basic knitted fabric 1 as a right-right knitted fabric with alternating rows of stitches from the knitting thread 6th and rows of weft threads from the weft thread 7th . Basically, it is preferred to start with a section in which the number of stitches is reduced in knitting direction s (in 8th the right section R) and then the sections in which the number of stitches is increased in successive rows (in 8th the middle section M and the left section L).

The knitted part according to the invention can have various shapes. In addition to the 1 and 6th The embodiment shown of a wrist bandage or a knee joint bandage can also be shaped, for example, as a chest bandage, glove, sock or stocking. In general, the knitted part can be used as a bandage or bandage to be placed on body parts, in particular on body extremities such as legs and arms.
