Abstract:
The present invention relates to a lockable connection system for components in medicine and medical technology that have fluids passing through them with a female, tube- or cone-shaped receptacle (11, 21, 41, 51) having an interior receptacle section and an external first fixing section, and a male, tube- or cone-shaped insertion element (12, 62, 72, 82, 92, 112, 132, 152) to be accommodated in the female receptacle section (11, 21, 41, 51) and an external second fixing section (14, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150) interacting with the first fixing section for fixing the connection system. The invention is characterized in that the first or second fixing section has at least two radially outward-protruding lobes (13, 13', 23, 23', 33, 33', 43, 43', 53, 53'), the radial external edge of which lies on a diameter greater than 7.83 mm and/or whose axial thickness at the base is greater than 1.3 mm. Alternatively, the invention is characterized in that the first or second fixing section has at least three radially outward-protruding lobes.
Abstract:
The invention relates to a connecting system for components through which fluid flows for medicine and medical technology, in particular infusion or transfusion tubes, selector valves, multi-way distributors, injection equipment such as needles, accesses or the like, and combinations thereof, comprising a female tubular receptacle, which comprises an inner receiving section and an outer first fixing section, and/or a male tubular plug element for reception in the female receiving section and an outer second fixing section, which cooperates with the first fixing section for fixing the connecting system. The invention is characterized in that the surfaces of the connecting system that come in contact with the fluid are produced at least in some sections from amorphous copolyester. The invention further relates to the use of amorphous copolyester for producing a corresponding connecting system.
