Abstract
An epidural connector has a housing in two parts, one of which contains a resilient, compressible slug with an axial bore into which an epidural cannula is inserted. The slug has a hexagonal external shape with flats separated from one another by rounded corners. The inside of the first part of the housing is of circular shape so that gaps are formed between the slug and the inside of the housing. The second part of the housing is screwed into the rear of the first part and has a female bore for receiving a male coupling. The forward end of the second part of the housing engages the rear end of the slug so that the slug can be compressed about the cannula and deformed into the gaps to accommodate cannulae of different diameters.
