The history of the 24mm pump flange is closely linked to the evolution of breast pump technology. Breast pumps have been around for over a century, but significant advancements began in the 20th century. Early breast pumps were manual, cumbersome, and often inefficient.

In the mid-20th century, electric breast pumps were introduced, revolutionizing breastfeeding by making it easier and more efficient to express milk. However, these early models were still quite rudimentary in design.

The 1980s and 1990s saw significant improvements in breast pump technology, with companies like Medela and Ameda leading the way. During this period, a range of flange sizes was developed to accommodate different nipple and breast sizes. The 24mm flange size became a standard option, as it was thought to fit a significant portion of women effectively. However, over time, it has become evident that the 24mm size is often too large for many women. Research and user feedback have shown that the majority of women actually require smaller flange sizes for a proper fit and comfort.

The predominance of the 24mm flange as a default size reflects an initial lack of understanding and support for the anatomical diversity among breastfeeding mothers. Many women experience discomfort and inefficient milk expression due to using flanges that are too large. This mismatch can lead to reduced milk supply and a negative breastfeeding experience.

Today, there is a growing awareness of the need for a wider variety of flange sizes that truly support the diverse needs of breastfeeding mothers. Companies are increasingly offering smaller flange sizes and more customizable options to ensure a proper fit for all users. This shift towards inclusivity and better support for all anatomical variations marks a significant improvement in the breast pump industry, aiming to enhance the breastfeeding experience through better technology and design.
