  • Sterile coupling
    Patent number: 7097209
    Abstract: Sterile coupling comprising a male and a female connector, each provided with a membrane device comprising a membrane surface covered with an adhesive at the exterior surface. When the connectors are brought into operation, the adhesive surface are contacted to form a bonded surface. Then, a hole is generated through the bonded surface and the sterile portions of the devices are brought into cooperations. The hole is formed by a rupture member arranged in one of the connectors. After rupturing, the membrane devices retract to a space formed between the cylindrical bodies of the connectors.
