Information for clinicians

This page provides additional information for health professionals, carers and partners about the manufacturing and medical regulation compliance of the Milkdrop silicone breast pump cushion. 



The Milkdrop breast pump cushion is a soft silicone standalone insert that fits a variety of existing breast pumps. It is to be used by lactating women to provide a softer interface between the breast and the existing breast pump.


The cushion is designed to make pumping more comfortable for women experiencing pain, damage or discomfort from using breast pumps by providing a softer interface* between the breast and the pump. Further benefits will be evaluated through post-market studies, including the effect of the cushion on the perception of pain, comfort and milk production.

*The Milkdrop cushion measures 10A on the Shore Hardness scale. Most breast pump heads inserts or cushions measure between 35 and 45A, and most breast pump funnels measure over 100A.
