    摘要： A breast pump includes a housing, a suction unit mounted in the housing, a rippled funnel for engaging a mother's breast, and an adapter for interconnecting same. The adapter is configured to sealingly support the funnel, frictionally sealingly support a bottle for collecting milk, and frictionally sealingly engage the housing. The adapter includes a tubular protrusion/stem defining a passageway for communicating air from the bottle to the suction unit to create a vacuum in the bottle. A pair of "O" rings are positioned on the protrusion to sealingly and stably engage the housing. A check valve is located in the protrusion to prevent back flow of milk from the bottle to the suction unit. The housing includes an outer surface defining a hand grip, and vacuum adjustment controls including a wheel for fine vacuum adjustment and a vacuum releasing push bottom are conveniently positioned on the hand grip. The housing includes a shroud that protects the bottle and that forms a stable arrangement that the entire unit will stand upright on a table. The shroud defines a battery holder and further includes a jack for mateably engaging an AC/DC transformer outlet for optional operation of the motor in lieu of batteries. The hand grip and the battery placement provide an optimal center of gravity located below the hand grip so that the breast pump can be easily, comfortably and securely held. The funnel includes three ring-shaped undulations providing increased comfort, size adaption and functionality to the funnel.

    摘要翻译： 吸奶器包括壳体，安装在壳体中的抽吸单元，用于接合母亲的乳房的波纹漏斗和用于互连的适配器。 适配器被配置为密封地支撑漏斗，摩擦密封地支撑用于收集牛奶的瓶子，并摩擦地密封地接合壳体。 适配器包括管状突起/杆，其限定用于将空气从瓶子传递到抽吸单元以在瓶中产生真空的通道。 一对“O”形环位于突出部上以密封并稳定地接合壳体。 止回阀位于突出部中，以防止牛奶从瓶子向抽吸单元反向流动。 壳体包括限定手柄的外表面，并且包括用于精细真空调节的轮和真空释放推动底部的真空调节控制器方便地定位在手柄上。 外壳包括保护瓶子的护罩，并形成一个稳定的布置，整个单元将直立在桌子上。 护罩限定了电池座，并且还包括用于与AC / DC变压器出口配合接合的插座，用于马达代替电池的可选操作。 手柄和电池放置提供位于手柄下方的最佳重心，使得吸奶器能够容易，舒适和牢固地保持。 漏斗包括三个环形起伏，提供更大的舒适度，适应尺寸和功能的漏斗。
