"breast pump" 的定义和意义

What is a "breast pump"?

A breast pump is a device used to extract milk from the breasts of lactating individuals. It operates by creating suction and mimicking the natural suckling action of a baby. Breast pumps are commonly used to collect and store breast milk for later use or to stimulate milk production. They provide a practical solution for mothers who need to express milk for various reasons, such as returning to work, relieving engorgement, maintaining milk supply, or allowing others to feed the baby.
