An apparatus for establishing aseptic/sterile connections including a substantially flexible, substantially transparent sterile barrier enclosing a terminal end of a conduit and a resilient, deformable support card which further includes an adhesive perimeter covered by a release paper and a rolling

An apparatus for establishing aseptic/sterile connections including a substantially flexible, substantially transparent sterile barrier enclosing a terminal end of a conduit and a resilient, deformable support card which further includes an adhesive perimeter covered by a release paper and a rolling membrane with a continuous, removable, yieldable, flexible strip material. A portion of the rolling membrane is removably adhered to the support card and overlies the end of the conduit. A force applied to the free end of the rolling membrane withdraws the entire rolling membrane to expose the end of the conduit so that an aseptic/sterile connection is achieved by adhering opposing support cards together, removing the rolling membrane to create a sterile corridor between a first sterile barrier and a second sterile barrier, and mating the terminal end of a first conduit and a second conduit together.
