Definitions

  • the invention relates to a medical knitted article, in particular in the form of an orthopedic bandage or a bandage, for contacting 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 article according to the invention can in particular in the form of a tubular bandage, a stocking or sock, or a glove.
  • the invention relates to a method for producing the medical knitted part.
  • a compressive knitted part orthopedic aid in the form of a bandage, orthosis, splint or support, or a compressive garment or knitted part for the 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 machined into the knitting part, which serves as access to the receiving device, the opening being machined into the knitting part as a slit formed in the transverse direction of the knitting in the knitting process.
  • the receiving device can in particular be designed as a pocket that is sewn, welded or glued onto the knitted part.
  • the functional element with 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 tempering effect or a medical effect on the part of the body to which the orthopedic aid is applied.
  • the described aid with insertable functional element proves to be complex and expensive, because after the opening in the knitted part of the knitted aid has been knitted, the pick-up device, for example in the form of a pocket, must be sewn, welded or glued onto the knitted part in a separate manufacturing step .
  • the sewing, welding or gluing of the receiving device for the additional functional element requires an additional work step, which has to be carried out separately after the knitting of the knitted part and for which additional machines, for example a sewing, welding or gluing machine, have to be used.
  • additional machines for example a sewing, welding or gluing machine
  • the object of the invention is to provide a simple, quick and inexpensive to manufacture knitted part for medical applications, which has a pocket into which a functional element can be inserted, which has a therapeutic effect on a part of the body on which the medical knitted part is applied is, can exercise.
  • the medical knitted part according to the invention can, for example, be in the form of an orthopedic bandage or a bandage for contacting a body part of a patient for medical or therapeutic treatment or for supporting the body part, the knitted part comprising a basic body knitted from a basic knitted fabric and at least one pocket for receiving a functional element, the pocket being seamlessly knitted into the base body and having an opening through which the functional element can be inserted and removed.
  • the knitted part according to the invention is knitted seamlessly on a flat knitting machine, the pocket being sack or tube-shaped and directly on without a seam or other fixing means Basic body is knitted.
  • 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.
  • the sack or tubular pocket is also knitted in.
  • At least one medically or therapeutically effective functional element can be introduced into the pocket, which is expediently designed as a sack or hose open on one side with the open side facing the base body.
  • the functional element can be, for example, a pressure body, a cushion body, an inelastic or elastic molded body and in particular a pad.
  • the functional element When the knitted part is applied to a body part of a patient, the functional element exerts a therapeutic or medical effect on the body part, for example a pressure and / or a temperature effect and / or a cushioning effect and / or an administration of a medically or therapeutically active substance to the body part .
  • the functional element can, for example, be impregnated with a medically or therapeutically active substance which is delivered to the body part if the knitted part according to the invention has been introduced into the pocket provided for this purpose with a corresponding functional element is applied to the body part of the patient, so that the substance stored in the functional element can diffuse into the body part through the knitted bag.
  • the functional element is expediently designed as a retard, which releases the medication at a slower rate.
  • the basic knitted fabric from which the basic body of the medical knitted part is made according to the invention can expediently be an extensible 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 area when it is in contact with a body part of a patient.
  • a functional element in the form of a pressure body or a pad is introduced into the pocket provided for this purpose in the knitted part according to the invention, the basic pressure exerted by the base body of the knitted part on the body part can be increased in certain areas or at points in the area in which the functional element abuts the patient's body part located.
  • 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.
  • the pocket which serves to hold the functional element is expediently knitted from a knitted pocket, the knitted weave of the knitted pocket being preferred and at least essentially corresponding to the knitted weave of the basic knitted fabric.
  • Both the basic knitted fabric of the basic body and the knitted pocket from which the pocket is knitted can, for example, be knitted as a right / left knitted fabric from an elastic or inelastic and stitch-forming knitting thread.
  • the pocket knitted fabric therefore has an elastic weft thread, which is integrated into the pocket knitted fabric or inserted under tension, the elastic weft thread preferably being inserted or integrated into the pocket knitted fabric only in regions. It is particularly advantageous here if the elastic weft thread is inserted into the knitted pocket only in the proximal, open area of the pocket.
  • the pocket knitted fabric which is only provided with a weft thread in some areas, exerts a compression effect only in the proximal region of the pocket, which is open and adjoins the basic body of the knitted part. This compression effect of the knitted pocket leads to a fixation of the functional element inserted into the pocket in the area of the opening of the pocket and prevents the functional element from accidentally slipping out of the pocket when the knitted part is carried.
  • FIG. 1 An embodiment of a medical knitted part according to the invention is shown in the form of a compression glove.
  • the glove has a base body 1 with a palm and back part and adjoining finger parts 7 for receiving the five fingers of a patient's hand.
  • the basic body 1 is designed as a knitted part and is produced from a basic knitted fabric 10 in a continuous knitting process.
  • the basic knitted fabric 10 is a compression knitted fabric with an elastic weft thread integrated into the basic knitted fabric under tension.
  • the basic body 1 When using a compression knitted fabric with an elastic weft thread integrated into the basic knitted fabric 10, the basic body 1 generates a (full) flat, uniform compression pressure on the body part when the knitted part lies against a body part of a patient.
  • the basic knitted fabric 10 is, however, not necessarily a compression knitted fabric.
  • the in Figure 1 The glove shown has in the base body 1 a pocket 3 knitted thereon, which is open on one side, namely in the proximal area, and closed in the distal area.
  • the pocket 3 thereby has the shape of a sack open on one side with an opening 2, the opening 2 of the pocket 3 facing the base body 1 and being connected to it.
  • a functional element can thereby be introduced into the pocket 3 through the opening 2.
  • Figure 2 is the glove of Figure 1 Shown in a functional position applied to a hand of a patient, the pocket 3 being turned inside out in the direction of the palm of the hand and a functional element 4 being introduced into the pocket 3, so that the functional element 4 comes to rest in the region of the palm. Since the glove from Figure 1 formed from a compression knitted fabric and thus designed as a compression glove, this exerts uniform pressure over the entire area or over a large area on the patient's hand.
  • the functional element 4 can be, for example, a pressure or cushion body, in particular a pad.
  • Functional position of the glove shown lies against the palm of the hand (with the pocket knitted fabric 5 of the sack-shaped pocket 3 still lying between the palm and the pad) and thereby exerts an additional pressure which is greater than the pressure exerted on the hand by the compression glove goes out.
  • the functional element 4 introduced into the pocket 3 thus acts as a pressure body.
  • an easily deformable cushion body for example made of a foam, or some other medically or therapeutically effective functional element 4 can also be introduced into the pocket 3.
  • the functional element 4 introduced into the pocket 3 exerts a therapeutic or medical effect on the body part on which the knitted part according to the invention is applied.
  • the opening 2 is closed by a seam 9.
  • the opening 2 is closed by the seam 9 after the functional element 4 has been inserted into the pocket 3.
  • the seam 9 prevents the functional element 4 inserted into the pocket 3 from accidentally slipping out of the pocket 3 when the knitted part is worn.
  • the basic knitted fabric 10 of the basic body 1 is knitted seamlessly on a flat knitting machine with a front needle bed and a rear needle bed opposite this, a front layer of the basic knitted fabric on the front needle bed of the flat knitting machine and a rear layer of the basic knitted fabric on the rear needle bed and the front and the back layer of the basic knitted fabric are knitted together so that a tubular basic body 1 is created.
  • the base body 1 of the glove has a palmar, front layer and a dorsal, rear layer and the finger parts 7, which serve to hold the fingers of one hand, are also tubular and seamless on the flat knitting machine in a continuous knitting process on the palmar and dorsal Knitted area of the base body 1.
  • the bag-shaped pocket 3 is also attached to the base fabric 10 of the base body 1 knitted in the knitting process on the flat knitting machine.
  • the sack-shaped pocket 3 also has a front layer and a rear layer, which are knitted on the front and the rear needle bed of the flat knitting machine and are knitted together in such a way that a tube-shaped or sack-shaped pocket 3 is created.
  • the pocket knitted fabric 5 preferably has a knitted weave which at least essentially corresponds to the knitted weave of the basic knitted fabric of the basic body 1.
  • the basic knitted fabric of the basic body 1 and thus expediently also the pocket knitted fabric 5 can be designed, for example, as a right / left knitted fabric.
  • an elastic weft thread is incorporated in the basic knitted fabric 10.
  • the pocket knitted fabric 5 in the Figures 3 and 4th In contrast, the exemplary embodiments shown have no weft thread.
  • the pocket knitted fabric 5 shown is knitted as a right / left hand knitted fabric from a stitch-forming knitting thread 6.
  • the knitting thread 6 can be an elastic or an inelastic thread.
  • the front layer v and the rear layer h of the knitted pocket knitted fabric 5 can be seen, the front layer v being knitted on the front needle bed and the rear layer h being knitted on the rear needle bed of the flat knitting machine.
  • the knitting thread 6 alternately forms loops and tuck loops both in the rear position h and in the front position v in the direction of the row of stitches m.
  • the stitches and tuck loops of the knitting thread 6 are knitted together in the stitch direction s to form a stitch and the front layer v is knitted with the rear layer h to form a tubular knitted fabric.
  • the tubular knitted fabric thus formed from the knitted pocket 5 forms the sack-shaped pocket 3.
  • Embodiment shown are knitted in individual stitches m 'of the back layer h and the front layer v additional stitches in the form of spiked. This formation of spots in the knitted pocket 5 allows the volume of the sack-shaped pocket 5 to be increased, so that large-volume functional elements 4 can also be introduced into the pocket 3.
  • the knitted pocket 5 can have an elastic weft thread, which is integrated into the knitted pocket 5 or inserted under tension.
  • the elastic weft thread pulls the sack-shaped pocket 3 together in the circumferential direction, as a result of which the pocket 3 exerts compressive pressure in the circumferential direction on the functional element 4 inserted into the pocket 3 and thereby fixes it in the pocket 3.
  • the knitted pocket can have a weft thread inserted into the knitted pocket or integrated under tension only in predetermined areas, which produces a compressive effect of the pocket 3 and contracts it in regions in the circumferential direction.
  • the compressive weft thread is provided in the region of the proximal opening of the sack-shaped pocket 3, which is connected to the opening 2 in the base body 1 of the knitted part.
  • the compressive weft thread in the region of the opening of the sack-shaped pocket 3 prevents the functional element 4 from being able to slip out of the opening 2 of the pocket unintentionally.
  • the fact that the compression-giving weft thread is provided only in regions in the region of the pocket 3 adjoining the opening 2, but not in the rest of the pocket region, ensures that the functional element 4 is easily inserted without resistance.
  • This process with steps (1) to (8) is repeated depending on the width of the pocket 3.
  • Has the bag 3 e.g. 20 needles width, there are 20 repetitions.
  • knitting is not - as usual - in a circle or tube, but in the "U" sequence from the front layer V to the rear layer H, and vice versa, i.e. 2 layers V in the front, 2 layers in the back H. This prevents the layers V, H from being joined in the area of the pocket 3, as a result of which the opening 2 is formed in the pocket 3.
  • the knitted part according to the invention can have various shapes. In addition to the in the Figures 1 and 2 In the embodiment of a glove shown, the knitted part can also be designed as a sock or stocking. Furthermore, the knitted part according to the invention can also be designed as a tubular bandage or bandage.
  • the knitted part according to the invention can be used in the orthopedic field to support or compressively treat body parts and joints. Furthermore, the knitted part according to the invention can be used to treat lymphatic insufficiencies, such as lymphatic or lip edema can be used. The knitted part according to the invention can also be used in the field of foot or hand rehabilitation. Furthermore, a knitted part which is expediently designed as a compression article according to the invention can be used in scar therapy, for example for the treatment of scars which result from burns or scalds.
  • the invention is not limited to the exemplary embodiments shown in the drawings. From the description of the function of the pocket 3 for receiving a functional element 4, it can be seen that, for example, the shape of the base body 1 of the knitted part according to the invention can be changed as desired.
  • the shape of the pocket 3 can also be adapted to a predetermined shape of a functional element 4, so that the functional element 4 can be inserted into the pocket 3 with a precise fit.
  • the knitted weave of the basic knitted fabric, from which the basic body is knitted, and the knitted weave of the knitted bag, from which the pocket for accommodating the functional element is formed can be varied and that all can be used to form the basic knitted fabric and the knitted pocket common knitted fabrics can be used.
