Hello Winnie,

I know it is confusing understanding which claims made by pump companies
may or may not be true. I myself have seen condensation build up in pump
tubing and have seen mold growing. I have even popped off the face
plates of some pumps and see dust, dirt and who knows what on the
diaphram. What impact could this have on possible contamination of a
pump? I guess only testing would tell us that.   I do know that the most
common pumps on the market all work with positive and negative pressure.
These are all suck and release pumps, no matter how you look at it. This
means airflow is being pulled away and towards the breast at the
different phases of the cycle. Not only could this aggravate any edema
in the breast, but it is hard on the nipple tissue. Theoretically with
two way airflow, could this mean that yeast or bacteria could be drawn
away from the breast or pushed back towards the breast, maybe even into
the pores of the nipples? What impact could this have on thrush and
mastitis rates?  What are the rates associated with pump use?  Has
anyone examined this?

"Pump In Style pump motors are not sterilizable, they have no filters
and
therefore organisms could *theoretically* get into the motor and be
blown
back through the tubing into the collection chamber."

 

I have never understood this argument, other than the fact that it comes
from the competing manufacturer.  Since the pump "sucks" rather than
"blows"
through the tubing, how can organisms be "blown" through the tubing into
the
collection bottle?
