  • Patent number: 9782299
    Abstract: The invention relates to an apparatus suitable for use in the negative-pressure therapy of the open abdomen, including a first bandage ply (11, 21, 31) having a first and a second side, as organ-protecting layer, the first side being intended for application to a wound base (3), more particularly exposed internal organs or the greater omentum, a second bandage ply (12, 22) provided separately from the first bandage ply and having a first and a second side, the first side of the second bandage ply (12, 22) being intended for application to the second side of the first bandage ply, a joining means by means of which the second bandage ply (12, 22), after application of the first ply (11, 21, 31) to exposed internal organs or to the greater omentum, can be joined to the first bandage ply (11, 21, 31), making it possible to avoid movement of the first bandage ply (11, 21, 31) with respect to the second bandage ply (12, 22) as far as possible during the therapy and/or facilitating simultaneous removal of first (11,

  • Patent number: 9604044
    Abstract: A connection device for use in the negative pressure therapy of wounds, includes a flexible conduit having at least two lumens and being constructed for impingement with negative pressure and/or fluid media; a coupling body made of an elastomeric flexible material, and non-detachably molded onto a wound-side end section of the conduit and being constructed for arrangement on a negative pressure bandage which covers the wound and seals the wound against the atmosphere, wherein the conduit communicates with a wound space through at least one opening in the coupling body; and a fluid inlet section for insertion through an opening in the negative pressure bandage into the wound space. The fluid inlet section is formed on the coupling body and protrudes over a walling of the coupling body, which walling faces the negative pressure bandage. The fluid inlet section is fluidly connected interiorly of the coupling body with a further lumen for delivering a fluid medium.

  • Publication number: 20130245582
    Abstract: The present invention relates to a wound dressing for use in negative-pressure wound therapy, in particular for wounds in the abdominal region. The wound dressing comprises a first flexible film with a first and a second side, with the first side being provided for application on the wound bed, more particularly on exposed internal organs or on the greater omentum, and with the first film furthermore having a multiplicity of openings distributed across the area. Moreover, the wound dressing comprises at least three conduit sections, applied to the second side of the first film, made of a flexible elastomeric material with a thickness (H) of at most 20 mm, with each of the conduit sections having at least one continuous cavity, and with each of the conduit sections having a flat design. Furthermore, the wound dressing is distinguished by virtue of the fact that, with the exception of the openings situated at the ends, each of the conduit sections has no further openings.

  • Publication number: 20130030395
    Abstract: A connecting device (2) for use in the treatment of wounds has a conduit (10) which can be evacuated and a flat, extended vacuum-tight carrier (12) on which the conduit (10) is held in a vacuum-tight fashion, wherein the carrier (12) can be disposed onto a vacuum dressing (6) covering the wound. The conduit (10) communicates with the wound space through openings. An adhesion-promoting layer (24) is provided on the side (22) of the carrier (12) facing the wound and has a middle supporting layer (26), a first adhesive layer (28) held on the supporting layer (26) and facing the carrier (12) and a second adhesive layer (30) held on the supporting layer (26) and facing away from the carrier (12). The adhesion-promoting layer does not block an opening (18) in the carrier (12).
