Definitions

  • Such wound care arrangements are used in particular in the context of so-called vacuum therapy. It has been shown that, in particular, the healing of chronic wounds can be promoted by applying negative pressure to these wounds. It has also proven to be advantageous if the wound is covered or filled with an open-pored foam or gauze as filling material, the wound is covered to produce a wound and optionally the filling material containing closed wound space and on the wound or the Filling material facing away from the covering a suction port is attached, via which the wound space can be connected to a designed for generating negative pressure suction device. In other arrangements, a flange of the suction port is covered by the cover device or in a pocket surrounding an opening of the cover.
  • the desired adjustment of the environment in the wound space can be effected particularly reliably if the water vapor permeability of the covering at least in sections 300 g / m 2/24 hr or more, particularly 500 g / m 2/24 hr or more, more preferably 750 g / m 2 / 24 h.
  • a filling material designed to fill the wound between the wound base and the covering device is provided, preferably a drainage layer for introducing the surface from the suction side facing the filling material the exudate to be sucked off the filling material is provided in at least one suction opening of the suction connection. If such a suction connection is provided, neither channel-forming projections on the boundary surface of the suction connection facing the filling material nor an expansion of the suction surface in the form of a disk-like shell are required.
  • this expedient in terms of a simple application of the covering device, this expediently has a coefficient of sliding friction in the range between 0.7 and 1.2, measured in accordance with ASTM 1894-08. In this case, a sufficient hold of the covering device can be achieved if the coefficient of static friction is between 0.8 and 1.5, more preferably between 1 and 1.25, measured in accordance with ASTM 1894-08. In this context, it has further proven to be expedient if the elongation at break of the covering device is more than 100%.
  • the suction connection of a wound care arrangement has a suction opening facing the wound space in use and a connecting device preferably designed as a pipe socket for establishing a connection between the suction opening and a suction hose, wherein the pipe socket is arranged on the side of the suction connection facing away from the wound space.
  • the suction opening can pass through a flange-like contact area of the suction connection, the contact area having a suction area preferably surrounding and preferably equipped with an adhesive attachment region with which the suction port can be glued to a wound space facing away from the boundary surface of the cover.
  • the contact area can also be at least partially covered by the covering device.
  • a wound positioned on a limb is inserted into the tubular cover sheet after a conventional vacuum therapy dressing unit or after the application or insertion of a filling material, so that the foil covers the entire wound area and the tubular covering foil over the edges survives the wound.
  • the film is expediently dimensioned taking into account its compliance that it rests tightly or gap-free at the wound edges.
  • the length of the tubular film can be adapted by cutting to the size of the wound.
  • the tubular film can also be delivered as an endless tube and assembled on site by cutting.
  • the so covered by the filling material and the cover sheet is sealed by commercially available adhesive film associations, for example under the trade name Suprasorb F of Lohmann & Rauscher GmbH, at its two axial ends sealingly connected to the skin surrounding the wound.
  • FIG. 4 shows a wound care arrangement designed with the suction connection according to FIG. 3, FIG.
  • FIG. 6 shows a wound care arrangement with a suction connection according to FIG. 5, FIG.
  • the contact surface 12 is completely covered by the drainage layer 40.
  • a fastening region 16 ' encircling the pipe connection 20, which, like the attachment region 16, can be provided with an adhesive layer which, prior to use of the suction connection 10 in a wound care arrangement according to the invention, comprises a detachable protective layer can be covered.
  • the suction connection according to FIG. 3 differs essentially from the suction connection according to FIGS.
  • the contact area 11 has, in addition to a suction opening 14, also a ventilation opening 80 through which the wound can be ventilated in a controlled manner To improve the flow conditions in the wound area in the sense of improving the exudate removal.
  • the ventilation opening 80 has a larger diameter than the suction opening 14.
  • the peripheral edge of the ventilation opening 80 in the contact area 1 can have a shoulder which, according to FIGS. 4 and 5, can be used as a support surface for an antibacterial filter 82. As a result, the flow resistance in the area of the ventilation opening 80 is increased, which, however, can be compensated for again by adjusting the diameter of the ventilation opening 80.
  • the antibacterial filter 82 is formed in the embodiment shown in the drawing of polytetrafluoroethylene and has a pore size in the range of 0.001, esp. 0.005, preferably 0.02, particularly preferably 0.1 to 5 microns. It is covered by the drainage layer 40 in the wound care arrangement according to FIGS. 6 a and 6 b. As explained with reference to FIG. 4, the suction connection according to FIG. 3, as well as the suction connection according to FIG. 1, can be mounted in such a way that it is glued on a covering film 60.
  • the covering device designed as a film tube is in the form of a truncated cone, that is to say it is conically spreadable.
  • One end such as the upper end 310, may be closed while the other, such as the lower end 312, may be open. Particularly preferably, the end is closed with the smaller cross-section.
  • the film tube can then be slipped over a hand in the manner of a stocking over a foot or possibly in the manner of a glove.
  • tubular cover films which may optionally also be applied to support foils, is intended, wherein the support foils can be released from the cover foil after application of the cover foils to the wound.
  • completely closed tubular films are advantageously used in the circumferential direction, which only have an opening at least at one axial end, wherein the opening required for the discharge of exudate via the suction port is formed in the tubular film after applying the tubular film to the wound.
  • the tubular film can be cut, for example, at the appropriate location.
  • other skin-compatible and water vapor-permeable films can be used. It is essential that the covering substantially airtight and waterproof limited the closed wound space, is germ-tight, has a suitable water vapor permeability, is biocompatible and skin friendly and can be cut and optionally applied using an additional support film.
