    • A method for producing a connection device for use in the negative pressure therapy of wounds, includes introducing a flexible conduit into an injection mold, the conduit being constructed for impingement with negative pressure and/or fluid media, and comprising at least two lumens, forming a coupling body at an end section of the conduit by injection molding an elastomeric material to the end section of the conduit, said coupling body being constructed for attachment to a negative pressure bandage which covers the wound and seals the wound tight against the environment, said the conduit being constructed for communication with the wound space through at least one opening, and attaching and fastening an end cap to the coupling body, thereby sealing the coupling body tight to the outside.
    • 一种用于生产用于伤口负压治疗的连接装置的方法,包括将柔性导管引入注射模具中,所述导管构造成用于与负压和/或流体介质冲击,并且包括至少两个流明,形成 通过将弹性体材料注射成型到所述导管的端部部分而在所述导管的端部处的联接体,所述联接体被构造成用于附接到负压绷带,所述负压绷带覆盖所述伤口并将所述伤口紧密地环绕环境密封,所述连接体 所述导管被构造用于通过至少一个开口与所述伤口空间连通,并且将端盖连接并固定到所述联接体上,从而将所述联接体紧密地密封到外部。

    • The invention relates to a connection device (2) for use in the negative pressure therapy of wounds, comprising a flexible conducting means (6) and a connecting body (4) made of an elastomeric flexible material which can be applied to a negative pressure dressing which covers the wound and seals the wound off from the atmosphere, wherein the connecting body (4) has a centrally arranged raised first area (8) which receives the conducting means (6), and a flatter flange-shaped second area (10) opposite the first area, which second area forms a contact plane (12) on the negative pressure dressing, wherein a conducting portion (46) which is closed on all sides and is formed by the central first area adjoins a free end of the delivery lumen (42) of the conducting means (6) which opens in the central first area, wherein said conducting portion first opens at a distal end into an interior (16) of the central first area (8) and from there is in fluid communication with the suction lumen (40) of the conducting means (6), characterized in that the central first area (8) has one single contiguous opening (20) which opens towards the negative pressure dressing in the contact plane (12), such that the at least one suction lumen (40) communicates with the wound space through said contiguous opening (20), and that extensions (22) integral with the first area (8) and extending in the contact plane (12) with free ends protrude into said contiguous opening (20) and form a means for preventing penetration of dressing or wound inlay materials sucked out of the wound space.
