Breast pump

Spectra hospital grade double breast pump Closed system breast pump meaning it is safe to sell this pump on to someone else This means there’s a barrier (sometimes called a ‘media separation’) between the breast pump and your expressed breast milk. A breast pump with a milk barrier is known as a closed system as it’s ‘closed off’ from the milk. The barrier prevents the milk overflowing and leaking into the pump mechanism, and helps ensure your expressed milk travels through a hygienic route. An open-system breast pump doesn’t have a milk barrier – but bear in mind that the risks of contamination are extremely small even if you do have this type of breast pump.
