milk pump

• Silicone balloon: This part is designed to ensure gas-liquid separation.

• Duckbill valve: This valve creates a one-way flow, allowing milk to move down into the bottle but not back up.

The device is often portable, rechargeable via a USB cable, and may have different modes like massage and expression to stimulate milk production. The materials used are typically PP, ABS, and silicone.
