    description
    The invention relates to a medical knitted part, in particular in the form of an orthopedic bandage or a bandage, for investment on a body part of a patient for medical or therapeutic treatment or to support the body part, according to the preamble of claim 1, and a method for Manufacture of such a knitted part. 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 EP 2 268 245 B1 designed as a compressive knitted part orthopedic aid 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 known, wherein the functional element is introduced into a receiving device, which is connected to an opening worked into the knitted part, which serves as access to the receiving device, the opening in the knitting process as a slot formed in the transverse direction of the knitted fabric (i.e. running in the direction of the course of the stitches) is incorporated into the knitted part. 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 on 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, for example in certain areas or at certain points goes beyond the compression pressure exerted over a large area and evenly by the compression part.
    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 course.
    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 introduced without hindrance, which has a therapeutic effect on a part of the body on which the medical knitted part is applied, 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 with the features of claim 1. Preferred embodiments and applications of the medical knitted part according to the invention emerge from the dependent claims. A method for producing a knitted part according to the invention with the features of claim 19 also contributes to achieving the object.
    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 to support the body part, the knitted part being a basic knitted fabric and knitted in a knitting direction has at least one pocket for receiving at least one functional element and a slot-shaped opening incorporated 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 obliquely 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 so that the slot-shaped opening extends in a slot direction which is oblique to the knitting direction. The slot 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 form 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 pocket is attached to the basic knitted fabric before or after the tube is formed, 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 knit on a circular knitting machine or on a flat knitting machine.
    In the bag, 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, at least one medically or therapeutically effective functional element can
    ment. 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 a patient's body, the functional element exerts a therapeutic or medical effect on the part of the body, 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 some 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 integrated 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 in a very efficient manner from a knitting point of view by transferring stitches of the basic knitted fabric from a row of stitches into the following row of stitches in the knitting direction (wale direction) at given transfer points in the basic knitted fabric. In order to generate the oblique course of the slot-shaped opening, the hanging points are arranged offset from one another by at least one stitch in successive rows of stitches in the direction of the course of stitches. The direction in which the transfer points are offset 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.
    In the method according to the invention for producing a knitted part, 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 running perpendicular to the knitting direction, formed from a knitting thread and for knitting the opening that runs obliquely to the knitting direction are first in the knitting direction and Several consecutive courses of the basic knit are knitted over the entire width of the basic knit, 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 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 increased and the second (right) section is due to the unused and still in The stitches hanging from the needles of the needle bed in the middle piece (right) come to lie next to the first (middle) section and between the first (middle) section and the second (right) section a slit is formed which extends obliquely to the knitting direction and which forms the opening .
    In a corresponding manner, after knitting the second (right) section, optionally a third (left) section can 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) section 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 that extends obliquely to the knitting direction is also formed between the first (middle) section and the third (left) section, the one
    forms further opening. 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 obliquely to the knitting direction. The inclination of the openings (slot direction) can be the same or different, ie the slot-shaped openings can run parallel at a distance from one another or enclose an angle with one another, for example between 10 ° and 170 ° and preferably in the range from ± 30 ° to ± 60 ° can lie.
    The knitting of two opposite openings can be advantageous, for example, if 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 inserting and 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 (seen in the knitting direction) upper ends of the respective opening can be knitted from the knitting thread in the method according to the invention after knitting the right section and possibly the left section 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 linking or sewing, whereby fraying of the opening, in particular at its ends, can be prevented.
    The bag, which serves to hold the functional element, is appropriately knitted in a separate knitting process on a circular or flat knitting machine from a knitted pocket, the knitted fabric of the pocket knitted fabric can at least substantially correspond to the knitted fabric of the basic knitted fabric. The pocket knitted fabric can be knitted, for example, as a right-to-right knitted fabric or as a right-to-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 introduce 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, when the functional element is introduced into the pocket, a resistance caused by the compressive effect of the weft thread must be overcome 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.
    In order to prevent the functional element from accidentally stepping out of 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 exchanged for another, therapeutically or medically effective functional element.
    These and other features as well as properties, advantages and effects of the knitted part according to the invention emerge from the exemplary embodiments described in more detail below with reference to the accompanying drawings. The drawings show:

    In Figure 1, a first embodiment of a medical knitted part according to the invention is shown in the form of a wrist bandage. The wrist bandage has a base body made of a basic knitted fabric 1 with an opening 2 knitted into it and a pocket 3 arranged on the inside (which faces the patient's forearm when the bandage is put on) for receiving a functional element 4. The ones in the basic knit
    1 knitted-in opening 2 is slit-shaped and runs obliquely to the knitting direction s. The slot-shaped opening 2 thus has a slot direction (longitudinal direction of the slot) which is inclined (here at an angle of approx. 45 °) to the knitting direction s. A functional element 4, indicated by dashed lines in FIG. 1, can be introduced into the pocket 3 through the opening 2 and also removed from the pocket 3 again. The inclination of the slot-shaped opening 2 in relation to the knitting direction s, which corresponds to the longitudinal direction of the bandage, facilitates the introduction and removal of the functional element 4.
    The functional element 4 can be, for example, a pressure or cushion body, in particular a pad. In the functional position of the glove shown in Figure 1, the pad rests on the forearm of a patient (with the knitted pocket fabric of the sack-shaped pocket 3 between the forearm and the pad) and thereby exerts an additional pressure in the area of the pocket 3, which is above the pressure exerted evenly on the forearm by the bandage. The functional element 4 introduced into the pocket 3 thus 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 another medically or therapeutically effective functional element 4 can be introduced into the pocket 3. In any case, the functional element 4 introduced into the pocket 3 has a therapeutic or medical effect on the part of the body to which the knitted part according to the invention is applied.
    The opening 2 can be closed by a seam. The opening 2 is closed by a seam after the functional element 4 has been inserted into the pocket 3. The seam prevents the functional element 4 inserted into the pocket 3 from accidentally slipping out of the pocket 3 when the knitted part is worn.
    To produce the basic body 1 of the knitted part according to the invention, such as the bandage shown in Figure 1, the basic knitted fabric 1 of the basic body is knitted 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 1, knitted as a flat knitted fabric, is 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 hose. The pocket 3 is fastened to the basic knitted fabric above the opening 2 before or after the formation of the tube, for example by sewing, gluing or welding. The pocket 3 is expediently designed in the shape of a sack or hose with at least one open side. The pocket 3 is attached to the basic knitted fabric 1 in such a way that an open side of the pocket 3 has an opening knitted into the basic knitted fabric 1
    2 communicates. The opening 2 serves as access to the (one or two-sided) open pocket 3 through which a functional element 4 can be inserted into the pocket 3 (or removed from the pocket).
    The pocket 3 is expediently 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 at least essentially corresponds to the knitted fabric of the basic knitted fabric 1. The basic knitted fabric 1 and thus also the pocket knitted fabric can be designed, for example, as a right-Z-left or preferably as a right / right-hand knitted fabric.
    To form the basic knitted fabric 1 of the basic body as a compression knitted fabric, it can be provided that an elastic weft thread is incorporated into the basic knitted fabric 1. In contrast, the pocket knitted fabric preferably has no weft thread.
    The knitting of the opening 2 into the basic knitted fabric 1 when knitting the basic knitted fabric 1 on a flat knitting machine with a front and a rear needle bed is explained in more detail below with reference to the drawings in FIGS. 2 and 3, the basic knitted fabric 1 in the example shown is designed as a right-to-right knitted fabric:
    When knitting the basic knitted fabric 1, a knitting thread 6 is knitted in a right-to-right knitted fabric (R-R) to form loops, as a result of which courses m, m + 1, etc. are formed which continue in the 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. In this way, there is a connection between the front and rear needle beds for each stitch. In order to generate a compression effect, an elastic weft thread can be introduced into the basic knitted fabric 1. In the knitting pattern shown in the drawing in FIG. 5, a weft thread 7 is introduced between each of the rows of stitches m, m + 1 that follow one another in the knitting direction s. In the knitting pattern in FIG. 5, rows of stitches m of the knitting thread 6 alternate with rows of wefts of the weft thread 7. This creates a flat knitted fabric which extends in the transverse direction (that is, perpendicular to the knitting direction s) over a predetermined width. This (lower) area of the basic knitted fabric 1 is denoted by "u" in FIGS. 2 and 3.
    At a point where an opening 2 is to be created (in Figure 3 from the row m + 2), the procedure is as follows: First, in the same way as in the lower area u of the basic knitted fabric 1, a first (right ) Part R knitted, with a reduction in the number of stitches of rows of stitches m + 2, m + 3, etc. following one another in knitting direction s in order to create 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 shown by the hanging arrows U in the knitting diagram in FIG. 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 row of stitches m + 2, m + 3, m + 4 etc. until a top row of stitches m + x is reached, where the opening 2 is to end (Figure 3).
    A second (left) section L is then knitted in a corresponding manner, the number of stitches being expanded 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 rows of wefts of the weft thread 7 are simply taken over into the next row by the continuation of the weft thread guide in successive rows.
    In the knitting diagram in FIG. 3, it looks as if the second section L would be above the first section R. Since the stitches of the lower section u of the basic knitted fabric 1, which were not used in the first section R, 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. A slot which extends obliquely to the knitting direction and which forms the opening 2 is formed between the first section R and the second section L.
    In order to close the slot-shaped openings 2 at their upper end, a further area in the form of an upper section o is now knitted over the entire width of the basic knitted fabric, corresponding to the lower section u of the basic knitted fabric 1 (with a row of wefts and a RR- Row alternating).
    FIG. 4 shows an enlarged schematic representation of a further knitted fabric for a knitted part according to the invention with two openings for introducing functional elements. The knitting of the two openings 2, 2 'is explained using the animated picture of FIG. 5: As in the exemplary embodiment of FIG Form rows of stitches m, m + 1, etc., which continue in knitting direction s. In the knitting pattern shown in FIG. 5, a weft thread 7 is also introduced between rows m, m + 1, m + 2, etc., which follow one another in the knitting direction s. In the knitting pattern in FIG. 5, rows of stitches m of the knitting thread 6 alternate with rows of wefts of the weft thread 7. This creates a flat knitted fabric which extends in the transverse direction (that is, perpendicular to the knitting direction s) over a predetermined width. This (lower) area of the basic knitted fabric 1 is denoted by "u" in FIG.
    At a point where the two openings 2, 2 'are to arise (in the example of Figure 5 from the row m + 2), the procedure is as follows: First, in the same way as in the lower area u of the basic knitted fabric 1, a first, middle section M (middle piece) is knitted, with the number of stitches m + 2, m + 3, etc. successive in the knitting direction s being reduced in order 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 shown in the knitting diagram of FIG. 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 row of stitches m + 2, m + 3, m + 4, etc. until a top row of stitches m + x is reached, at which the openings 2, 2 'are to end (FIG. 5).
    A second, right-hand section R is then knitted in a corresponding manner, the number of stitches being expanded in successive courses m + 2, m + 3, etc. (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 into it
    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 rows of wefts of the weft thread 7 are in turn simply taken over into the next row by the continuation of the weft thread guide in successive rows.
    In the knitting diagram in FIG. 5, it looks as if the second, right-hand section R would be above the first, middle section M. Since the stitches of the lower section u of the basic knit, which were not used in the first, middle section M, but are still hanging on the needles in the needle bed, the second, right-hand section R comes "down" and is ultimately to the right of the first, middle section M. Here, between the first, middle section M and the second, right-hand section R, a slit which extends obliquely to the knitting direction and which forms the first opening 2 is formed.
    In the example shown in Figures 4 and 5, in addition to the first opening 2, a further opening 2 'is knitted into the basic knitted fabric 1 in a corresponding manner. 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 knitting of the stitches of the third, left section L takes place on the stitches still on the needles of the needle bed in the left part, 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 still open towards the top (o). In order to close the slot-shaped openings 2, 2 'at their upper end, a further area in the form of an upper part o is knitted over the entire width of the basic knit, corresponding to the lower part u of the basic knit 1 (with a row of wefts and a RR- Row alternating).
    The openings 2, 2 'knitted into the basic knitted fabric in this way run at a predetermined angle of approximately 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 to be knitted into the basic knitted fabric 1. The angle between the knitting direction s and the slot direction (longitudinal direction of the slot 2 or 2 ') is expediently between ± 10 ° to ± 80 °, preferably between ± 30 ° to ± 60 °. FIG. 6 shows a further exemplary embodiment of a medical knitted part according to the invention in the form of a knee joint bandage, in which two opposing openings 2, 2 ′ have been knitted into the basic knitted fabric 1 in the manner described above and shown in FIG. The knee joint bandage in turn has a base body made of a basic knitted fabric 1 with the two openings 2, 2 'knitted into it and a pocket 3 arranged on the inside (which faces the patient's knee when the bandage is put on) for receiving a functional element 4. The openings 2, 2 'knitted into the basic knitted fabric 1 are slit-shaped with a slit direction (longitudinal direction of the slit) which is inclined (here at an angle of approximately 45 ° or 315 °) to the knitting direction s. The slot directions of the two openings 2, 2 'are at an angle of approximately 90 ° to one another. On the inside of the knee joint bandage there is a tubular pocket 3 open on two sides, the open ends of which are each connected to one of the two openings 2, 2 '. A functional element 4, indicated by dashed lines in FIG. 3, can be introduced into the pocket 3 through the openings 2, 2 ′ and also removed from the pocket 3 again. 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, makes it easier to insert and remove the functional element 4. As can be seen from FIG. 6, the two ends of the annularly curved functional element 4 protrude from the openings 2, 2 'and can be fixed to one another outside the pocket 3, for example with a hook or Velcro fastener.
    In Figures 7 and 8 is a schematic representation of a further knitted fabric for a knitted part according to the invention with two parallel and spaced openings 2, 2 'for introducing functional elements. The knitting of the two openings 2, 2 'in accordance with the manner described in the exemplary embodiment of FIG. 5 emerges from the knitting diagram of FIG. 8, after knitting the lower section u first with the knitting of the right section R, then the middle section M and finally the left section L is knitted. Finally, the upper section o is knitted over the entire width of the basic knit 1 as a right-right knit with alternating rows of stitches from the knitting thread 6 and rows of weft threads from the weft thread 7. Basically, it is preferred to start with a section in which the number of stitches is reduced in the knitting direction s takes place (in FIG. 8 the right section R) and then the sections are knitted in which the number of stitches is increased in successive rows (in FIG. 8 the middle section M and the left section L).
    The knitted part according to the invention can have various shapes. In addition to the embodiment of a wrist bandage or a knee joint bandage shown in FIGS. 1 and 6, the knitted part can also be shaped, for example, as a thoracic 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.
    The knitted part according to the invention can be used, for example, in the orthopedic field for supporting or compressive treatment of body parts and joints. Furthermore, the knitted part according to the invention can be used for the treatment of lymphatic insufficiency, such as, for example, lymph or lip edema. The knitted part according to the invention can also be used in the field of foot or hand rehabilitation. Furthermore, an expedient as
