Sterile fluid line coupling members

Abstract

Abstract A pair of interengageable coupling members (1, 2) for interconnecting tubing, teat parts and such parts of sterile fluid administration equipment to provide a fluid passage therebetween which is free from contamination each coupling member (1, 2) comprising a body defining a longitudinally extending fluid pathway (29, 18) and a pair of coaxial, radially spaced apart frusto-conical surfaces (3, 3'; 4, 4') which are adapted to sealingly engage with corresponding surfaces on the other coupling member (2, 1) such that the inner coupled surfaces (3', 4') interconnect the fluid pathways (29 and 1 8) while the outer coupled surfaces (3, 4) surround the inner coupled surfaces in such a way that the inner frusto-conical surfaces are substantially shielded to prevent contamination by persons touching those surfaces, and that there is defined between the pairs of coupled surfaces (3', 4'; 3, 4) a sealed annular space (11) which can contain a sterilising solution. The members can be moulded from suitable plastics materials.
