Claim:
1. A connection device for use in the negative pressure therapy of wounds, comprising: 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, said coupling body being 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, said conduit communicating with a wound space through at least one opening in the coupling body; a fluid inlet section for insertion through an opening in the negative pressure bandage into the wound space, said fluid inlet section being formed on the coupling body and protruding over a walling of the coupling body, which walling faces the negative pressure bandage, said fluid inlet section being fluidly connected interiorly of the coupling body with a further lumen for delivering a fluid medium, wherein the coupling body comprises at least three other lumens extending adjacent one another, wherein a first one of the at least three other lumens is configured as rinsing lumen, wherein at least one second one of the at least three other lumens is configured as suction lumen, wherein a third one of the at least three other lumens is constructed for delivering a fluid medium to the wound, and wherein the rinsing lumen and the suction lumen are fluidly connected at their ends, and wherein the rinsing lumen is closed in a direction of the wound and is fluidly connected with one or more other ones of the at least three lumens only via its distal end; and an end cap attached to the coupling body, thereby sealing the coupling body tight against the environment.
