Medical fluid communication couplings

摘要: A medical coupling system is disclosed for apparatus in fluid communication, the comprising a plurality of groups couplings, each member (10) group including first (32) and second (22) complementary connector parts, or part (32/22) being shaped to be mateable only together with corresponding parts same group, one end having spigot (36), adapted non-rotatable fitting into an aperture (26) (22), further sleeve (40) rotatably mounted thereon, internal screw thread (43) engaging external (23) holding use. The outer peripheral shapes flanges (38/28) on and/or may enlarged versions shape ready recognition that two halves are easy turning.
