2. Setup and Flange Sizing

Proper flange sizing is crucial for comfort and effective milk expression. Using an incorrectly sized flange can lead to discomfort and reduced pumping efficiency.

2.1 Determining Your Flange Size

To find your correct flange size, measure your nipple diameter in millimeters. The inner diameter of the flange (B) should be 2-3mm larger than the diameter of your nipple (N). During pumping, you should observe free movement of your nipple within the flange tunnel, with little to no suction of the areola into the tunnel.

2.2 Using a Mobile Ruler App for Measurement

You can use a mobile ruler application to assist in measuring your nipple size.

1. Download a free "Pocket Ruler" app for iOS or "Millimeter" for Android phones.
2. Stimulate your nipple to perk it up.
3. Place your phone screen perpendicular to your nipple.
4. Align the nipple base with the zero mark in the corner of the app screen.
5. Slide the second measurement bar on the screen to the opposite nipple base. This will give you your nipple measurement in centimeters for iOS or millimeters for Android.
6. Choose a flange that is 2-4mm larger than your measured nipple diameter.

2.3 Attaching the Flanges

Once the correct size is determined, securely attach the 21mm replacement flanges to your compatible NCVI breast pump assembly. Ensure a tight seal to prevent air leaks and maintain suction. The soft, flexible rim of the NCVI flanges is designed to create a good seal against the skin.

3. Operation

The NCVI 21mm replacement flanges are engineered for improved efficiency and faster milk ejection. Their 108° angle and oval shape are specifically designed to better fit the natural contour of the breast, facilitating easier milk flow during pumping sessions. The soft rim ensures a comfortable and secure fit, preventing milk leakage.

4. Maintenance and Cleaning

Regular cleaning of your NCVI replacement flanges is essential for hygiene and optimal performance.

4.1 Cleaning Instructions

• Disassemble all flange components from the breast pump.
• Wash all parts that come into contact with breast milk immediately after each use.
• Use warm, soapy water and a soft brush to clean the flanges thoroughly.
• Rinse all components under clear running water.
• Allow parts to air dry completely on a clean surface or drying rack.
• The flanges are not dishwasher safe. Hand washing is recommended to preserve the integrity of the material.
• The material is BPA-free, ensuring safety for you and your baby.

5. Troubleshooting

If you experience issues with your NCVI replacement flanges, consider the following:

5.1 Discomfort or Pain During Pumping

• Incorrect Flange Size: This is the most common cause. Refer to Section 2.1 "Determining Your Flange Size" and Section 2.2 "Using a Mobile Ruler App for Measurement" to re-evaluate your nipple size and ensure you are using the correct 21mm flange, or if a different size is needed.
• Improper Alignment: Ensure the flange is centered over your nipple before starting to pump.

5.2 Reduced Milk Output or Inefficient Pumping

• Incorrect Flange Size: An ill-fitting flange can significantly reduce milk expression. Re-check your flange size as described in Section 2.1 and 2.2.
• Loss of Suction: Ensure all breast pump components, including the flanges, are properly assembled and securely connected to the pump. Check for any cracks or damage to the flange or other parts that might cause air leaks.
• Worn Parts: Over time, parts like valves or membranes can wear out, affecting suction. Inspect all components for signs of wear and replace as necessary.

5.3 Flange Not Sealing Properly

• Improper Attachment: Ensure the flange is fully seated onto the breast pump connector.
• Damaged Rim: Inspect the soft, flexible rim of the flange for any tears or damage that could compromise the seal. Replace if damaged.
