Definitions

  • the invention relates to a dressing material according to the preamble of claim 1 and to a treatment solution according to the preamble of claim 16.
  • wounds can be improved by a moist environment, in particular media which support wound healing or which contain at least one medicament, for example solutions or gels, can also be used.
  • a currently practiced method is that the dressing material or a layer of this material consisting of an absorbent material is soaked with the relevant solution and then the dressing material is applied to the wound. The handling is cumbersome and especially when treating larger and deeper wounds and when dressings are changed frequently, a specially trained staff is necessary.
  • the object of the invention is to show a dressing material which, with simplified use, enables an improvement in wound healing.
  • a dressing material according to claim 1 is designed to solve this problem.
  • a treatment medium that can be used with the dressing material is designed according to claim 16.
  • the dressing material according to the invention has the advantage that, in the case of simple use, it allows wound healing in a moist environment using media which promote wound healing and / or contain medications, in particular solutions, and also significantly increases the time period within which a dressing change must take place.
  • the dressing material according to the invention possible to change the dressing only three days after the first care of a wound, ie at a time at which a deep wound has already closed to such an extent that the risk of infections is significantly reduced.
  • This long residence time of the dressing material on the wound also ensures wound rest that is necessary for rapid healing, particularly within the first few days after the wound has been treated. This is possible because the chamber for the treatment medium has at least one connection led out of the dressing material for refilling and / or renewing the treatment medium.
  • the chamber is formed by at least one channel which extends in several sections and / or turns over the surface of the dressing material. This channel is then preferably at least one piece of hose.
  • FIG. 1 shows a schematic partial representation of the layer structure of a dressing material according to the invention, the individual layers actually connected to one another in the dressing material being shown separated from one another for the sake of clarity in the manner of an exploded view;
  • Figure 2 is a simplified schematic representation of a top view of the material of Figure 1;
  • 3 shows a schematic partial representation of the layer structure of a further dressing material according to the invention.
  • 4 - 7 different graphics relating to the time course of wound healing in animal experiments.
  • the dressing material which is also particularly suitable for treating open, deep wounds, is essentially designed as a multi-layer flat material, for example with a square or rectangular cut.
  • the dressing material 1 consists of a first, sterile layer 2 on the outside, which forms the support on the wound and is formed by a perforated flat material, for example perforated film or grid made of a suitable plastic, for example PVC.
  • the single-layer outer layer 2 is followed by a layer 3, which is formed by several layers of a sterile, absorbent and air and moisture-permeable material, for example a coarse fabric or a non-woven material.
  • the layer 3 consists of several layers of sterile gauze, for example four layers.
  • Layer 4 has semipermeable properties, ie it is permeable to air and gases, but not permeable to liquids.
  • a lumen or tube piece 5 is fastened, which extends in a meandering manner almost over the entire area of layer 4 and thus over the entire area of dressing material 1 and forms two ends or connections 6, which are led out laterally from the dressing material 1, namely at the Embodiment shown such that these ends 6 protrude on two opposite peripheral sides 1 'and 1 "of the dressing material.
  • the tube piece 5 which forms a channel for receiving and distributing a treatment medium, in particular a liquid or aqueous treatment medium, is on its inside the dressing material 1, i.e. between the layers 3 and 4 extending length so that a finely divided outlet of the treatment medium present in the tube piece 5 is possible in the layer 3.
  • the piece of hose 5 is, for example, finely perforated.
  • the projecting ends 6 are preferably each formed by a tube length that does not have this perforation.
  • the individual layers 2, 3 and 4 with the tube piece 5 arranged between the layers 3 and 4 are connected to one another in a suitable manner, for example along the edge of the dressing material 1 and / or point-wise also within the dressing material 1.
  • the dressing material 1 is placed on the wound to be treated with the layer 2 and then fixed, for example, at the edge by means of an adhesive tape 7 or in some other way.
  • a solution suitable for wound treatment is supplied via one end 6, for example via the upper end in FIG. 2, and until such solution emerges at the other end or connection 6 and thus the entire chamber formed by the hose section 5 is filled with this treatment solution. Then both ends 6 are closed, for example with a suitable plug.
  • the treatment solution emerging from the tube piece 5 is finely distributed over the entire dressing material over the layer 3 and thus in particular also over the entire wound area.
  • the solution in Hose section 5 is renewed and replaced several times a day, for example twice a day.
  • the wound material is optimally kept occlusive and moist by the dressing material according to the invention, so that a significantly improved wound healing is achieved.
  • the particular advantage of the dressing material according to the invention is that a change of the dressing is only necessary after several days, for example only every three days, so that the first change of the dressing material usually takes place at a time when even a deep, open wound has already closed to such an extent that the risk of an additional infection when changing the dressing can be excluded.
  • the large time interval between the application of the dressing material and the first change of this dressing material ensures, in particular, that the wound is calm for the first healing process within the first days after the care of a wound.
  • the dressing material according to the invention thus combines the advantages of wound healing in a moist environment with the advantage of long wound rest, which promotes the healing process, particularly in the first few days.
  • FIG. 3 shows a further exemplary embodiment of the invention in a schematic representation and in section of a dressing material 1 a, which in turn has a multi-layer construction and also serves to improve wound healing in a moist environment.
  • the dressing material 1 a consists of a lower layer 10 with which this material is placed on a wound.
  • This layer 10, which forms the sterile pad on the wound, is formed from a sterile perforated flat material, for example from a perforated or lattice-like film made from a suitable plastic, for example from PVC or silicone.
  • a layer 11 is provided on the layer 10, which serves as a distribution layer for the treatment liquid and for this purpose is made, for example, from a sterile, soft and absorbent material, for example from gauze or from a nonwoven material (fleece).
  • a layer 12 which contains the liquid treatment medium in encapsulated form, in such a way that the treatment medium is opened via the layer 11 by opening or breaking the layer 12 or the capsules there distributed to the underside of the dressing material and thus to the wound area.
  • a cover layer 13 is provided, which consists of a semi-permeable flat material, ie a flat material which is not or largely impermeable to the liquid treatment medium, but is permeable to air and gases.
  • the covering layer 1 3 also covers the dressing material 1 a or the various layers and layers of this dressing material from the side and is skin-compatible at the edge which is at the level of the underside of the layer 10 adhesive order 14 provided.
  • the dressing material 1 a is sterile closed on the side with which it is applied to a wound with a removable cover layer 15. Layer 15 is subtracted in use.
  • the dressing material In use, the dressing material, after removal of the cover or protective layer 15, with the then exposed layer 10, is placed on the wound and fixed around the wound with the adhesive layer 14. By breaking the layer 12, the encapsulated treatment liquid is released.
  • the dressing material 1 a is preferably designed such that when changing a dressing, the layer 10 of the existing dressing is separated from the adjacent layer 11 is and the layer 10 thus remains on the wound, so that the rest of the wound and thus the healing process are not affected by a change of dressing.
  • the fresh dressing material used when changing the dressing then corresponds to the dressing material 1 a, but without the layer 10, ie the formation is made such that in addition to the protective layer 1 5, the layer 10 can also be removed from the dressing material 1 a if necessary.

  • composition of the treatment solution is given below:
  • the low pH of the treatment medium not only creates an acidic and therefore optimal wound environment.
  • the acidic environment is particularly also stimulates the metabolism that promotes the healing process.
  • the treatment medium also has a microbacteriostatic effect due to the acid in connection with the iron content, ie it creates a milieu which prevents the growth of germs and bacteria and has a repulsive effect on them, so that inflammation is caused by germs entering a wound and developing there are effectively prevented.
  • the treatment medium (solution) described above is also particularly suitable in combination with the dressing material 1 or 1 a. for use in skin grafts to supply or cover the transplant site, but also to supply the donor side (e.g. buttocks) where the transplanted skin has been removed.
  • the treatment medium (solution) described above is also particularly suitable in combination with the dressing material 1 or 1 a. for the treatment of postoperative wounds and thereby decisively improves the healing process, as has been demonstrated by tests on pigs.
