Patent ID: 8267127

Claim:
A connector section for use in a fluid transfer operation, said connector section comprising a hollow cylindrical outer body having: (a) a distal shoulder portion radially protruding from said outer body and terminating with an opening through which a proximal end of a fluid transfer component can be inserted for coupling; (b) a closed proximal cap having a central portion comprising connection means protruding proximally from it to connect to a distal end of a fluid transfer apparatus; (c) a needle holder protruding into the interior of said outer body from the central portion of said closed proximal cap for retaining therein at least one conduit comprising a sharp pointed end and further provided with an aperture through which fluid is transferred during said fluid transfer operation; and (d) a double membrane seal actuator reciprocably displaceable within the hollow interior of said outer body; wherein said double membrane seal actuator comprises: (i) a cylindrical actuator casing; (ii) a proximal membrane that seals the proximal end of said casing; (iii) a distal membrane that seals the distal end of said casing, wherein a part of said distal membrane protrudes distally from said casing; and (iv) at least two resilient arms which are connected at a proximal end thereof to an intermediate portion of the exterior of said casing and comprise enlarged elements at their distal ends.
