Definitions

  • the invention relates to a device for wound treatment and a wound covering plaster made according thereto, which can be advantageously used in particular in various methods of vacuum wound treatment of surface wounds.
  • Drainage tube is then subjected to a negative pressure, whereby the wound fluid can be sucked off.
  • this approach also requires considerable skill of the medical practitioner, because during wound care, all separately inserted device components are to be fixed, which often can not be accomplished by one person alone.
  • Vacuum wound treatment have been developed, for example, in
  • Negative pressure is a procedure that has been practiced for many years, which positively influences the healing of deep and large wounds by permanent wound irritation.
  • This type of vacuum wound treatment is described in detail, for example, in DE 694 25 8B1 T3, DE 692 29 940 T2 and DE 692 24 847 T3, which is why reference should here be made to this only.
  • No. 6,695,824 B2 discloses a wound dressing covering for outer flat wounds which consists of two layers, wherein the first layer is applied directly to the wound and the second layer has an outwardly acting moisture barrier. Between the said layers a plurality of hose-like supply lines are provided which provide a moisture supply to the wound
  • the hard port is a disadvantage to the patient.
  • the use of hard ports for small wounds with respect to air circulation in the wound area unsuitable because a small adhesive surface is not sufficiently ventilated beyond the wound area. This obstructs the aspiration of the wound secretion. Only by a special pump, by the
  • Suction hose allows ventilation of the wound, the suction process of wound secretion can be maintained.
  • Wound area are, for example, in WO 2008/039314 A1,
  • the present invention has for its object to provide a multivalent usable device for vacuum wound treatment, which allows sufficient ventilation of the wound even when using commercially conventional vacuum pumps on reaching the required negative pressure in the wound area without it consuming
  • Control means for the vacuum pump requires as well as a subsequently manufactured Wundabdeckpflaster.
  • the essence of the invention consists in that a part of a conventional wound cover plaster, which covers the wound surface completely airtight to the outside, is provided with at least one opening lying above the wound surface, on which a layer stack is provided is, at least from a filter disc, in particular
  • Bacteria filter disc at least one vapor diffusion-open, but at the same time watertight paper-like disc and at least one further, also provided with an opening which is preferably arranged corresponding to the opening in the wound film, provided flexible film which directly or indirectly sealing all of the aforementioned Schichtp beautician with the wound film in the boundary region includes and closes, wherein the arrangement of at least one waterproof disc always takes place so that it is provided on the side facing the outside air layer stack final.
  • adjustable vacuum pumps defined adjust adjustable throttle effects of the proposed device. If the proposed device is already integrated into a wound cover, additional steps for the surgeon's attachment are unnecessary. If the device is offered separately on a carrier foil, the surgeon only has to bring in an opening in the wound cover whose diameter is slightly larger than the opening of the opening of the proposed device to be placed on it, in order not to change the throttle effect predefined by it. This is easy to do even for an inexperienced surgeon.
  • the main advantage of the proposed device is that no
  • Vacuum pumping must be made.
  • Vacuum range is specifiable adjustable. Due to the fact that ventilation of the wound via the pump itself is eliminated, the risk of germ infections by the pumping paths is no longer present.

  • a fourth exemplary embodiment according to FIG. 5 the possibility is shown of dividing said layer packages and applying them to both sides of a wound cover plaster 2 or a carrier foil 3.
  • Such an embodiment is within the scope of the invention.
  • the provision of discs 12 is not necessarily required, but in any case such a disc should move the device in the direction
  • Figure 6 outlined with reference to only two discs 11, 12 an advantageous embodiment in which the diameter of the filter discs 1 1 and the discs 12 are tapered stepwise designed such that a Jardinnkegelstumpfieris structure with the smallest diameter is formed on the respective outer side adjacent disc. Of course, the smallest disc diameter is still larger than the opening above it.
  • Such Design Simplifies in the manufacture of the attachment of the flexible film 14, which conforms more easily to the provided stack.
  • the wound-facing opening with an approximately half the opening diameter as the opening facing the outside air.
  • the diameter of the opening facing the outside air was from 6 mm to 1 mm with a simultaneous decreasing determination of diameters of the wound facing the opening of 3 mm to 0.5 mm in their positive
  • Embodiment are used, they are initially against each other at the edge to fix before they are in the composite with the carrier film 3 on the provided with an opening 21st
  • Wundabdeckpflaster 2 are connected airtight in the remaining peripheral area. This composite thus produced then realizes the function of the film 14 described for the other exemplary embodiments.
  • venting of the wound takes place after 12 to 15 seconds
  • Vacuum wound treatment never a negative pressure of 200 mbar is exceeded even for a short time.
  • the device according to the invention can be produced inexpensively and can be used in all known vacuum wound treatment methods (also for pumps at intervals).

Abstract

L'invention concerne un dispositif de traitement des plaies, qui peut en particulier être utilisé avantageusement dans différents procédés de traitement par le vide de plaies superficielles. L'invention vise à proposer un dispositif de traitement par le vide utilisable de manière polyvalente, lequel assure une aération suffisante de la plaie lorsque la pression négative nécessaire dans la zone de la plaie est atteinte, même en cas d'utilisation de pompes à vide courantes dans le commerce, sans que des moyens de commande complexes soient nécessaires pour la pompe à vide. A cette fin, une partie d'un pansement pour plaies usuel (2) qui recouvre entièrement la plaie de manière perméable à l'air vers l'extérieur est munie d'au moins un orifice (21) situé au-dessus de la surface de la plaie et sur lequel est placée une pile de couches (1) qui est constituée d'au moins un disque filtrant (11), d'au moins un disque de type papier (12) permettant la diffusion de vapeur mais néanmoins étanche à l'eau et d'au moins un autre film flexible (14) éventuellement muni d'un orifice (141) disposé pour correspondre à l'orifice (21) du pansement pour plaies (2), lequel film entoure et ferme de manière étanche directement ou indirectement, latéralement et dans la zone périphérique (15) tous les constituants ci-dessus de la pile de couches avec le pansement pour plaies (2). L'agencement d'au moins un disque étanche à l'eau (12) se fait toujours de telle manière qu'il est effectué ensuite sur la face de ladite pile de couches (1) orientée vers l'air extérieur.
