USPTO Patent Application: Vacuum Wound Dressing Connection Device
Summary
The USPTO has published a patent application (US20260083898A1) for a connection device designed to create a vacuum-tight fluidic connection between a vacuum wound dressing and a vacuum source. The application was filed by PAUL HARTMANN AG and includes specific structural features to prevent tube collapse under vacuum.
What changed
This document is a publication of a patent application filed with the USPTO, specifically application number US20260083898A1, titled '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'. The application, filed by PAUL HARTMANN AG, details a connection device with a support unit designed to prevent the connecting tube from collapsing under vacuum conditions, ensuring a continuous fluid pathway for vacuum wound therapy.
As this is a patent application publication, it does not impose immediate regulatory requirements or compliance deadlines on regulated entities. However, it signals potential future product development and innovation in the medical device sector, particularly for wound care. Companies in this space may wish to monitor the patent's prosecution and eventual grant, as it could impact their own product designs or intellectual property strategies.

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.
