Abstract
Abstract Sterile connectors which utilize tabs or strips, portions which can be withdrawn from apertures which are to be interconnected in sterile fashion are disclosed. The connectors disclosed are utilized in conditions of differential pressure between the inside of conduits to which the connectors are coupled and the surrounding ambient. Contamination resulting from air flow due to the pressure differential is prevented by encasing the tab or strip in a sleeve or extension which isolates the strip or tab from the surrounding ambient. When a pair of sterile connectors is mated, deformable washers are brought into contact and the tabs or strips are pulled through channels in the washers into the sleeves or extensions while portions of the washers remain in contact forming an hermetic seal.
