Insert shield 21 mm

A well-fitting inner shell is important for comfortable and efficient pumping. Choosing the right size will ensure the pumping goes smoothly. Good to know, the nipple diameter determines the inner shell size, not the breast size.

Measuring your nipple is very simple. Use a tape measure or ruler to
measure the diameter of the nipple at the base, excluding the areola. Read the
size in millimetres (mm).

Select the appropriate breast shell based on the size measured:

For a nipple diameter of 13-15 mm, use 17 mm insert shield

For a nipple diameter of 15-17 mm, use 19 mm insert shield

For a nipple diameter of 17-19 mm, use 21 mm insert shield

For a nipple diameter of 20-22 mm, use 24 mm inner shell

No two breasts are the same, so you may need different sizes for each of your breasts. Therefore, you should measure the nipples of both breasts.

Read the user instructions beforehand. Before use the pump for the first time, sterilise the milk container, valve and diaphragm chamber in boiling water for up to 5 minutes. Make sure all the parts are completely dry. Allow the parts to cool on a clean cloth. Attach the breast pump and place it in your bra. Keep your upper body upright while pumping. Do not lean forward or backward more than 45°.

Finished? Gently remove the pump carefully from the bra. Do not turn the breast pump upside down during this process. You can easily pour the expressed milk into a bottle or breast milk storage bag using the opening in the milk container.
