Duckbill valves are commonly used in breast pumps to create a closed system that helps maintain suction and prevent milk from flowing back into the tubing. While not all breast pumps require duckbill valves, they are a popular component in many models.
Duckbill valves serve a few important functions in a breast pump:
Suction control: Duckbill valves help regulate the suction level in the breast pump. They allow the milk to flow from the breast shield into the collection container while maintaining the necessary suction to express milk effectively.
Hygiene and closed system: Duckbill valves help create a closed system between the breast shield and the collection container, preventing milk from entering the tubing or motor. This design helps maintain hygiene by reducing the risk of contamination and the need for frequent cleaning of the tubing.
Milk flow control: The design of the duckbill valve allows for controlled milk flow. When the valve is compressed against the breast shield during suction, it opens to allow milk to flow. When the suction is released, the valve closes, preventing milk from flowing back into the tubing or breast shield.
While some breast pumps may use alternative mechanisms or designs to achieve similar functions, duckbill valves have become a popular choice due to their effectiveness in maintaining suction and preventing milk contamination. However, it's always important to consult the user manual or manufacturer's instructions for your specific breast pump model to understand its requirements and recommended maintenance.
We help Legendairy Milk to develop the duckbill valves. And also do the test for the duckbill valves. If you want to do different color or different sizes/designs, Please connect with us.
