Information for clinicians


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.

Milkdrop breast pump cushion pilot preliminary observations

Report summary:

  1. 92% of women found pumping more comfortable

  2. comfort increased (score: 5 /10 to 9 / 10 where 10=very comfortable).
  3. nipple swelling decreased (score: 6 /10 to 0 /10 where 10=severe and 0=none)
  4. nipple swelling decreased (6 /10 to 0.5 / 10), redness decreased (6 /10 to 0.5/10) and damage decreased (4/10 to 0/10) for women identifying as having an uncomfortable pumping experience.
  5. 73% of women collected about the same or more milk.

Further benefits will be evaluated through post-market studies, including the effect of the cushion on the perception of pain, comfort and milk production.

Frequently Asked Questions

What are the intended benefits of the cushion?
Preliminary observations from our pilot indicate that lactating women perceive lower levels of pain, redness and swelling in the nipple, and higher levels of comfort when using the cushion on their existing pump. Most women perceive that they collect the same or more milk when using the cushion on their existing pump. However, 15% of women have difficulty with milk flow due to the 'bulkiness' of the cushion. We are developing a cushion specifically for these women, which will be available in June. Download our pilot preliminary observations report

Are you available outside Australia? 

We have not yet registered with medical device regulators outside Australia, but plan to soon.
What do you mean by ‘soft’?
The cushion is 3-4x softer than existing breast pump cushions and over 10x softer than existing breast pump heads. The Milkdrop cushion measures 10A on the Shore Hardness scale measured with a durometer. Most breast pump heads inserts or cushions measure between 35 and 45A, and most breast pump funnels measure over 100A.
