This is a Manual Massage Breast Pump, a hand-operated device designed for comfortable and convenient breast milk expression. The pump consists of a breast shield (flange) with a soft, petal-shaped or cushioning silicone insert (often described as a massage cushion) designed to gently stimulate the breast and promote milk let-down while ensuring a snug fit. The ergonomic handle is pressed to create the necessary vacuum/suction to mimic a baby's natural sucking motion. Manual pumps are popular for their portability, silent operation, and the control they give the user over the suction strength and rhythm. They are generally made from safe, food-grade, and BPA-free plastic (PP) and soft silicone materials, which are easy to sterilize. This type of pump is ideal for occasional pumping, travel, or as a cost-effective backup to an electric pump.
