Breast Milk Collection Cups FAQ

How to assemble Breast Milk Collection Cups:

1. Attach the diaphragm to the flange. Ensure it is securely in place.
2. Attach the valve to the flange and push firmly to ensure it is properly connected.
3. Insert the spout on the collection cup into the hole at the top of the breast shield. Push the collection cup into the breast shield. There should be an audible 'click'.
4. Determine your flange size and insert the silicone flange insert into the collection cup. This will provide a better fit and comfort.
5. Attach the tubing with the green connector to the collection cup. The green connector should already be attached to the tubing but can be removed and reattached when necessary.
6. Connect the other end of the tubing to your breast pump.
