A manual breast pump is a hand-operated device used for expressing breast milk. It typically consists of a breast shield, a pump handle, and a collection bottle. Unlike electric pumps, it requires manual effort to create suction, allowing the user to control the rhythm and pressure. Manual breast pumps are lightweight, portable, and silent, making them ideal for occasional use or travel. They are also more affordable than electric pumps. However, they may require more time and effort to express milk. Popular brands include Medela, Philips Avent, and Haakaa, with designs that prioritize comfort and efficiency.
