CONNECTION DEVICE FOR CREATING A VACUUM-TIGHT FLUIDIC CONNECTION BETWEEN A VACUUM WOUND DRESSING AND A VACUUM SOURCE, VACUUM WOUND THERAPY KIT, AND VACUUM WOUND THERAPY SYSTEM

Abstract

The invention relates to a connection device (22) for creating a vacuum-tight fluidic connection between a vacuum wound dressing (16) and a vacuum source (12), said device comprising: an elongated single-or multi-lumen connecting tube (24), in particular a film tube, which comprises a distal end portion (28) and a proximal end portion (26), it being possible to fluidically connect the distal end portion to the vacuum wound dressing in a vacuum-tight manner, and it being possible to fluidically connect the proximal end portion to the vacuum source in a vacuum-tight manner; and a support unit (46) which is located in a tube lumen (38) of the connecting tube, the support unit preventing the connecting tube from collapsing, in particular collapsing due to vacuum conditions, and being permeable to fluid in the longitudinal extension of the tube lumen. According to the invention: the support unit comprises at least one flat material web portion (48); the flat material web portion, in order to support the connecting tube, is structured by elevations (54) formed integrally with a plane (52) of the flat material web portion; and a continuous intermediate space (56) is formed between the elevations so that fluid can be transported through the intermediate space in the longitudinal extension of the tube lumen.
