A breast shield connects the breast, breast pump (via tubing), and milk container in a pumping setup. Unlike a one-piece flange, a detachable breastshield cannot be used on its own. It must be paired with either a base connector or a closed system connector to function properly.
The detachable design gives moms more flexibility while keeping the same connectors and pump models. It allows for:
- More size options – find the best fit for comfort and efficiency.
- Different shapes – to match personal preference or pumping needs.
- Space-saving storage – shields can be packed and carried more easily.
Breast side – This side contacts the breast, areola, and nipple. The size of a breast shield is defined by the tunnel’s inner diameter, which is directly related to comfort during pumping.
Connector side – This side attaches to the base connector. Milk flows through the shield tunnel into the connector and finally into a container. A secure fit between shield and connector is essential to prevent leakage.
Maymom offers a variety of detachable breastshields to suit different purposes. To further increase compatibility, we’ve also developed two accessories – the Shield Converter and the Shield Sleeve – so moms using other pump brands can still enjoy a wide range of shield sizes.
