Flange Sizing Guide
Proper flange sizing is critical for comfort and effective milk expression. An incorrect size can lead to discomfort, nipple damage, and reduced milk output. The 19mm insert is designed for mothers whose nipple diameter requires this specific size.
How to Determine Your Nipple Size:
- Step 1: Measure Your Nipple Base: After a pumping session, use a ruler or measuring tape to measure the diameter of your nipple at its base (where it meets the areola) in millimeters. Do not include the areola in this measurement.
- Step 2: Select Flange Size: Choose a flange or insert size that is 1-3mm larger than your measured nipple diameter. For example, if your nipple measures 17mm, a 19mm insert would be appropriate.

Setup and Assembly
The Ameda 19mm flange inserts are designed for easy integration with your existing Ameda breast pump system.
- Clean and Sanitize: Before first use and after each subsequent use, ensure the flange inserts are thoroughly cleaned and sanitized according to the "Cleaning and Maintenance" section.
- Insert into Flange: Gently push the 19mm silicone insert into the neck of your Ameda 25mm breast flange or Ameda GLO flange. Ensure it is seated snugly and evenly, creating a smooth tunnel for your nipple.
- Assemble Pump Kit: Attach the assembled flange with the insert to your breast pump collection bottle and connect to the pump tubing as per your specific Ameda breast pump's instructions.

Operating Instructions
Once the 19mm flange inserts are correctly assembled with your Ameda breast pump, you can begin your pumping session.
- Positioning: Center your nipple within the opening of the 19mm insert. Ensure that your nipple moves freely within the tunnel without excessive friction or rubbing against the sides.
- Comfort and Suction: Begin pumping at a low suction level and gradually increase it to a comfortable setting that allows for effective milk flow. You should feel a gentle tugging sensation, not pain.
- Observe Milk Flow: A proper fit helps maximize milk production. If you experience discomfort, reduced milk output, or notice your nipple rubbing, re-evaluate your flange size.

Cleaning and Maintenance
Proper cleaning and maintenance are essential for hygiene and extending the life of your flange inserts.
After Each Use:
- Disassemble: Carefully remove the silicone inserts from the breast flanges.
- Rinse: Rinse all parts that came into contact with breast milk under cool running water to remove milk residue.
- Wash: Wash parts in warm, soapy water using a mild dish soap. Use a soft brush if necessary to clean crevices.
- Rinse Thoroughly: Rinse all parts thoroughly under running water to remove all soap residue.
- Air Dry: Place parts on a clean paper towel or drying rack and allow them to air dry completely. Do not use a cloth towel, as it may transfer germs.
Sanitizing (Once Daily or as Recommended):
Sanitize parts by boiling them in water for 5-10 minutes or using a steam sterilizer designed for breast pump parts. Refer to your breast pump's manual for specific sanitization recommendations.

Troubleshooting
If you encounter issues while using your Ameda 19mm flange inserts, consider the following:
- Discomfort or Pain During Pumping:
- Re-evaluate your nipple size using the "Flange Sizing Guide." The 19mm insert might be too small or too large.
- Ensure your nipple is centered in the tunnel and moves freely.
- Check for proper assembly of all pump parts.
- Reduce suction level if it's too high.
- Low Milk Output:
- Verify flange size. An ill-fitting flange can restrict milk flow.
- Ensure all pump parts are correctly assembled and sealed.
- Check pump suction strength and tubing for damage or kinks.
- Consider hydration and overall well-being.
- Inserts Not Staying in Place:
- Ensure the insert is fully seated and pushed firmly into the larger flange.
- Check for any damage or wear on the insert or flange that might prevent a secure fit.
