The newer guidelines from the Milk Banking Association of North America
recommend a closed system where the air doesn't circulate into the
flange/bottle part for moms pumping for NICU babies. What I understand
is that an open tubing system like Medela's pulls air in and out of the
tubing, down into the bottle and back up. This is why the Symphony
tubing gets condensation in it. While you mostly only see the
condensation near the flange part, I wonder if enough liquid moves up,
could it "park" itself on the pump body where the tubing attaches? And
then go down into the next users tubing. If you look at the tubing
systems of the cheap drugstore brands, you can see how milk might go
into the motors direct from the tubing. Ameda is one example of a closed
system with a barrier between the flange and the tubing. Dr. Brown,
Playtex, and Avent also say theirs are closed systems. (I do sell or
rent pumps myself but I do work for a government agency that uses a
closed system for pumps.)
