The portable milk pump Momcozy is designed for breastfeeding women to express and collect breast milk. It creates a vacuum around the nipple and collects the milk in a container. The pump offers three modes: Stimulation (fast, short suction bursts), Expression (slow, deep suction bursts), and Mixed (a combination of both). A silicone diaphragm prevents milk from entering the vacuum system, ensuring safety. This milk pump is intended for single-user use.
