A breast milking machine is a mechanical or electronic device that removes milk from human breasts safely and efficiently. Purpose: It helps collect breast milk for feeding a baby later or for relieving breast fullness. Main components: Pump unit – creates suction using air pressure. Breast shields (cups) – soft cones that fit over the breasts to form a seal. Tubing – connects the pump unit to the breast shields. Milk containers – bottles or bags that store the milk after it is pumped. Control system – lets the user adjust suction strength and rhythm.
