Shaped around you

Every mum is different. Your breast shape is unique and can change throughout your breastfeeding journey. With our new PersonalFit Flex™ breast shield, you can easily adapt the way your Medela breast pump fits to help you find the most comfortable, effective, position to express.

More milk with a higher energy content in half the time

Unlike a single pump, Medela Swing maxi pumps simultaneously from both breasts and allows you to express more milk with higher energy content.

Our research shows that the unique combination of double pumping with Medela 2-Phase Expression® technology delivers more milk with a higher energy content than expressing from each breast in turn.

Easy and time-saving breast pump

The Medela Swing maxi combines the quality of the Medela Swing with a more powerful motor as it is made for double pumping. Compared to single pumping, double pumping can cut expression time in half and remove 18% more milk. 

A more natural pumping experience

When your baby latches on, he sucks quickly at first to start the milk flow, then more slowly to feed. Medela 2-Phase Expression® technology mimics these instinctive rhythms for a more natural-feeling and comfortable pumping experience.

Simple to operate, comfortable to use

Medela Swing maxi has a very simple design and is extremely portable. It is easy to assemble and disassemble for cleaning, and all parts can be sterilised in a microwave for convenience.

It can also help to increase and sustain milk supply. Equipped with research-based 2-Phase Expression Technology, the pump switches automatically from stimulation to expression phase or can be switched manually. Mothers can also choose their most comfortable vacuum level. Swing maxi provides convenient and effortless pumping sessions with high efficiency and comfort. It can be used with a mains adaptor and the option of battery operation combined with the beltclip guarantees maximum mobility.

  • Double pumping with 2-Phase Expression technology: shown to express on average 18 per cent more milk
  • Helps to maintain and increase milk supply when not directly breastfeeding
  • Twice as fast as single pumping — Saves up to two hours per day when exclusively pumping

What is 2-Phase Expression Technology?

2-Phase Expression is a pumping technology that mimics the baby’s natural sucking rhythm. It uses short, stimulating bursts followed by longer patterns to provide optimal milk flow. Research shows that babies initially use short, fast sucks to stimulate the Milk Ejection Reflex. Once the milk begins to flow, babies change to a slower, individual rhythm to actually feed.

  1. Stimulation phase - When babies first go to breast, they suck faster to start milk flowing. Pumping rhythm of >100 cycles/minute. Fast and efficient to start milk flow.
  2. Expression phase - After milk flow or "let-down" starts, babies breastfeed with a slower suck to remove milk. Slower pumping rhythm of between 42 and 87 cycles/minute. Slower to mimic nutritive sucking with regular milk flow

PersonalFit Flex™ Breast Shield

It’s a whole new pumping experience, personalised to you.

The new PersonalFit Flex™ breast shield was developed with the help of a team of research scientists and breastfeeding mums. It’s designed to easily adapt to your shape, and encourages your milk flow by helping prevent compression of the milk ducts. This makes it easier for every mum to find the pumping position that’s most comfortable for her. The result? More comfortable, more efficient expression, shaped around you.

Our research scientists tested the PersonalFit Flex™ breast shield in four clinical studies with breastfeeding mums. Across more than 1,000 pumping sessions, they proved it delivered more comfort and efficiency. Like every Medela product, our Flex™ breast pumps are designed to make breastfeeding easier, so you can feed your baby with your amazing milk for longer.

PersonalFit Flex breast shield is compatible with all Medela breast pumps (use the original connector that came with your Medela breast pump).

What do I do if there is low or no suction when pumping with the Swing Maxi breast pump?

Make sure the breast shield forms a complete seal around the breast.

Make sure the tubing end fits securely into the pump body & motor.

Perform rinsing procedure.

What are the PersonalFit Flex™ Breast Shields made of?
Medela PersonalFit Flex™ Breast Shields are made of food grade Polypropylene (PP) and Thermoplastic elastomers (TPE).

Is the material safe for mom and baby?
Yes, the material is made without BPA, natural rubber latex and phthalates.

How should I clean my PersonalFit Flex™ Breast Shields?
The PersonalFit Flex Breast Shields should be washed and sanitized prior to first use. They should continue to be washed after each use and sanitized once daily. Cleaning instructions for the PersonalFit Flex Breast Shields are the same as the cleaning instructions for your other breast pump parts that come in contact with your breast or breast milk; please refer to the breast pump instructions for use for detailed cleaning instructions.

How does the PersonalFit Flex™ Breast Shield yield more milk vs the traditional, 90 degree shields?
The new 105° opening angle and oval shape of the PersonalFit Flex breast shields allows more flexibility for mom to position the shield in different ways while she pumps, based on what’s comfortable for her. When let-down occurs, mom’s milk ducts get bigger – the new shape and angle allows the milk to flow more freely. Changing the opening angle of the flange from 90 degrees to 105 degrees made a difference; it better matched the contour of the breast and reduced compression of the milk ducts, which allows milk to flow more freely through them. This change resulted in increased volume of milk expressed during a pump session - 11.8 percent more overall on average. The 11.8 percent is the average but every mom’s personal experience will differ.

What breast pumps can you use the shield with?
PersonalFit Flex™ Breast Shields can be used with all Medela breast pumps. Make sure you use the original connector that came with your Medela breast pump. (*Only the Flex breast shield can work with all Medela breast pumps. Flex connector can only be used with Medela Swing Flex, Swing Maxi Flex and Freestyle Flex breast pump.)
