The Harmony breast pump is intended for single use only.
Medela is constantly researching and developing pumping technology to create a more efficient, natural and comfortable way to pump. All Medela pumps intended for personal use are equipped with research-based 2-Phase Expression technology, PersonalFit Flex breast protectors and easy-to-use but effective pre-programmed pumping settings (in electronic pumps).
2-Phase Expression technology:
At the beginning of each feeding, the baby uses short, quick suckings to stimulate the mother's let-down reflex. When the milk starts to flow, the baby switches to slower, stronger suctions, sucking as much milk as possible at once. Medela pumps imitate this natural sucking behavior of babies.
PersonalFit Flex/Flex™ technology:
With a 105-degree opening angle, a soft edge and an oval shape for a better fit, the PersonalFit Flex™ breast pump puts less pressure on the milk ducts than traditional breast pumps, making pumping more efficient and comfortable. More comfort for you, more milk for your baby - clinically proven.
Here's how you can find the right size Medela breast pump for you:
Pumping should not hurt. To make it as comfortable and effective as possible, Medela offers five sizes of breast pads. This guide will help you determine the best size for you based on your nipple diameter.
Step 1: Use a ruler or measuring tape to measure the diameter of the nipple from the base (center) in millimeters. Do not include the nipple area.
Step 2: Based on your measurements, determine the size of the Medela breastplate.
Example: If the nipple size is 16 mm in diameter, the recommended Medela breast rubber size is 21 mm.
Nipple diameter (Ø mm) maximum 17 mm = Breast size 21 mm
Nipple diameter (Ø mm) enmm = Breast pad size 24 mm
Nipple diameter (Ø) max. 23 mm = Breast pad size 27 mm
Nipple diameter (Ø mm) maximum 26 mm = Breast pad size 30 mm
Nipple diameter (Ø mm) maximum 32 mm = Breast pad size 36 mm
