Is a breast pump patented?

Short answer: specific designs of a breast pump have been patented many times, but "a breast pump" as a general idea is not what is protected. What matters is the exact combination of features in your version.

What this means for your idea

Because patents cover specific combinations of features, the useful question is not “has a breast pump been patented?” but “has my combination of features been described before?” Baby and child products are heavily patented and safety-driven; compare the locking, restraint and cleaning features carefully.
