I have a question for you lovely breast feeders! I've been toying with the idea of buying a used breast pump (due in March) and have read a lot of controversial things. Many people buy pumps and attempt to use them for a month then never touch them again then sell their $300 systems for $100. I've read that if you get a used pump you have to replace pretty much everything but the motor (which is obvious to me), but I've also read that you should never get a used pump (open system) because there are parts that cannot be sterilized and things like HIV and over infections can be transmitted from one user to another and to the baby--however, this has never actually happened.
If you want a second hand pump, it's fine so long as it is a closed system meaning no milk (or bodily fluids) can get into the motor. Then you can replace the parts that do come into contact with the milk and it's all good!
Problem with open systems is the motor, which you haven't replaced, can harbour milk, bacteria, etc. which can then find their way back into the pump parts leading to infection. A closed system prevents this. Hence why closed systems can be rented out, by hospitals or lactation consultants.
I have a used pump in style... I replaced the tubes, and it cost us $50 total. It is a great pump. We couldn't have managed the $250. I looked at youtube videos about the design, and it is possible to take the motor out of the backpack and sterilize the interior of the machinery if you have any doubts about it.
go for a closed system and buy new pumping parts - much cheaper that way
although I wouldn't want to use a pump with someone else's manky old milk in it, you/your baby won't get HIV from it - HIV is a very fragile virus and doesn't last for long outside the body.
Bacteria and fungal infections are a different matter.....
Stupid question, but how would milk get inside the motor? I have the Pump In Style in the tote bag and the motor seems pretty removed from the actual liquid.
The idea is that milk vapor could get sucked all the way down the tube and into the diaphragm (not really the motor)... then it could possibly stay wet in there and grow stuff, which then would have to make it the reverse direction... I dunno. I dont really believe its plausible, so I just replaced the tubes myself.
