Abstract
The invention relates to a wound dressing and to a device for use in negative-pressure wound therapy, in particular for wounds in the abdominal region, and also to methods for producing the device. The wound dressing includes at least one flexible film for application onto the wound bed, more particularly onto exposed internal organs or onto the greater omentum, and furthermore at least one pocket, which is present on the side of the wound dressing that faces away from the wound during use and which simplifies the uniform application and placement of the wound dressing on the wound bed.
Claims21
A wound dressing (10) for use in negative-pressure wound therapy, in treatment of abdominal wounds, comprising:
- i) a first flexible film (1) that forms a planar surface having a first and a second side, with the first side being provided for application on a wound bed (13), and with the first flexible film (1) furthermore having a multiplicity of openings (6) distributed evenly across the first flexible film (1) and which are capable of enabling fluid communication through the first flexible film (1);
- and
- ii) at least three pockets (25), each of the at least three pockets include an opening (27) that predominantly is directed toward a center of the wound dressing (10), the at least three pockets (25) and the openings (27) are present on and above an uppermost surface of the first flexible film (1) that faces away from a wound during use and simplifies a uniform application and placement of the wound dressing (10) on the wound bed (13),
- wherein there is no additional conduit on the second side of the first flexible film (1).
A device (40) for use in negative-pressure wound therapy, for treatment of abdominal wounds, comprising:
- a) a wound dressing (10) which includes:
- i) a first flexible film (1) that forms a planar surface having a first and a second side, with the first side being provided for application on a wound bed (13), and with the first flexible film (1) furthermore having a multiplicity of openings (6) distributed evenly across the first flexible film (1) and which are capable of enabling fluid communication through the first flexible film (1);
- and
- ii) at least three pockets (25), which include an opening (27) that predominantly is directed toward a center of the wound dressing (10), the at least three pockets (25) and the openings (27) are present on and opened above an uppermost surface-of the first flexible film (1) that faces away from a wound during use and simplifies the uniform application and placement of the wound dressing (10) on the wound bed (13), characterized in that there is no additional conduit present which is applied to the second side of the first film (1);
- and
- b) an airtight cover material (16) for air-impermeable closure of a wound and wound surroundings, which air-impermeable enclosure provides a wound space formed thereby, and a negative-pressure port, which can be applied to the air-tight cover material (16) on a side that faces away from the wound, for a functional connection of the wound space to a negative-pressure source (21) situated outside of the airtight cover material (16) such that negative pressure can be set in the wound space and liquids can be suctioned out of the wound space.
