Model # 17061: This Ameda pump is so compact it fits into a purse. The patented, easy-to-use design provides control and flexibility by varying the frequency and degree of the handle squeeze. The handle assembly eliminates the need for electrical outlets or batteries, and the one-hand design allows you to pump one breast while baby nurses on the other. By using two breast pumps, you may dual-pump to save precious time. Both of these methods stimulate the let-down reflex and enhance milk flow. Mothers may also pump directly into any standard baby bottle or freezer bag.
