The Risk of Using Second Hand Pump
Breastpumps can be classified as home-use or hospital-use. Home-use grade breastpumps, which can be purchased in the market, are for individual use. With opening system design, breastmilk cannot be totally protected from entering the inner part of the pump. There is the risk that any germs or bacteria remaining in breastmilk may enter into the pump. Thus, using or borrowing a used home-use grade breastpump, is unhygienic and unsafe even using new accessories, such as tubing, collection bottle, breastshield and connector.
Only hospital-use breastpumps, e.g. Symphony, are designed in such a way that breastmilk never touches the inner parts of the pump.
