Abstract

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 t…
