Abstract
A method for contamination-free transfer of liquid from one container to another, and devices to carry out the method are disclosed. Contamination-free transfer means that during the transfer process there is no (1) leakage of (a) the liquid, (b) air contaminated by the liquid, and (c) vapor from the liquid to the surroundings, and (2) surrounding contaminants from outside the containers that contact the liquid. The method's advantages include its simplicity, and the contamination-free transfer as defined above. The devices are adapted to effect contamination-free transfer of a hazardous drug to and from any container equipped with a standard connector port.
Claims7
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.
