Medela Swing Maxi Flex double electric breast pump is infused with patented and research-based 2-Phase Expression Technology. Through research, Medela has learned that there are two distinct phases of how babies breastfeed. The first phase, known as stimulation phase is when the baby first goes to the breast and sucks fast to initiate the milk flow. The second phase of expression occurs after milk flow or œlet-down begins. The breast pump includes a soft-touch, ergonomic swivel handle - to utilise our research-based, patented 2-Phase Expression Technology. Through research, Medela has learned that there are two distinct phases of how babies breastfeed. The first phase, known as stimulation phase is when the baby first goes to the breast and sucks fast to initiate the milk flow. The second phase of expression occurs after milk flow or œlet-down begins. During this phase, baby breastfeeds at a slower suck rate for continued milk flow.At Medela, we integrated this natural sucking behaviour into our breast pumps to create Harmony the first manual breast pump to offer 2-Phase Expression Technology. Harmony's single vacuum manual settings are easy to adjust, making the pumping experience convenient and more comfortable. Mothers have the flexibility to switch between the modes by adjusting the handle. This is the key to efficient breast pumping and a major reason why Medela is the leading breast pump recommended by doctors for new mothers. Mothers can significantly reduce the time taken to express, because the milk flows faster and more easily.EFFICIENT PUMPING WITH CLINICALLY RESEARCHED TECHNOLOGY As the world's leading brand in breastfeeding research, Medela breast pumps are designed to re-create an experience that most closely resembles baby's natural sucking patterns and speeds. The Swing Maxi Flex breast pump comes with clinically-researched settings for both stimulation and expression phases of pumping, so that moms can customize their pumping experience, but still express milk in the most efficient manner.EASY AND COMFORTABLE PUMPING The Swing Maxi Flex breast pump provides a comfortable, customizable experience with easy-to-use controls. It automatically switches from stimulation (starting) mode to expression mode after 2 minutes, but you can switch into expression mode whenever milk starts to flow. Pick from 11 different vacuum levels across both stimulation and expression modes for your desired comfort.DOUBLE PUMPING More milk with higher energy content than expressing from each breast in turn MORE MILK WITH FLEX: The innovative 105 ° angle of the breast shield reduces pressure and thus supports the milk flow.
