Title:
CONNECTION DEVICE FOR USE IN NEGATIVE PRESSURE WOUND THERAPY
Document Type and Number:
WIPO Patent Application WO/2013/034374
Kind Code:
A1
Abstract:
The invention relates to a connection device (2) for use in negative pressure wound therapy, with a suction line (10) that can be subjected to a negative pressure and with a planar, negative pressure-tight and flexible carrier means (12) for the suction line (10), the suction line (10) being retained negative pressure-tightly thereon, wherein the carrier means (12) can be positioned substantially negative pressure-tightly on a negative pressure wound dressing (6) surrounding the wound and sealing it against the atmosphere, such that the suction line (10) can communicate with the wound area through at least one opening in the carrier means (12) and in the negative pressure wound dressing (6), wherein the suction line (10) is flexible and flat and in a longitudinal section (8) on the wound side is connected in a non-detachable and flat manner to the carrier means (6) for the intended use over at least 70% of its surface area as projected vertically onto the carrier means (6), wherein the principal planes of the carrier means and the suction line resulting from their planar shapes are parallel to one another and wherein the thickness (D) of the composite consisting of suction line (4) and carrier means (6) is at most 7 mm; according to the invention it is proposed that a fluid supply line (40) for supplying a fluid medium to the wound area be placed on the carrier means (12) in the same plane as the suction line (10), the thickness of the fluid line not exceeding that of the suction line (10), and that the fluid supply line (40) is run in a sealing manner through an opening (42) in the carrier means (12) and protrudes from the wound-facing side (22) of the carrier means (12) and can project through the opening (20) in the negative pressure wound dressing (6) into the wound area or into a wound overlay (50) provided therein.
