    摘要： A baster or like device includes a liquid tube and a squeezable, resilient suction bulb. The suction bulb includes a series of radially spaced scallops or indentations about its outer surface, which provide ergonomic advantages in gripping the suction bulb. Further, the spacing between the indentations defines a series of lands, which function to bias the suction bulb to its undeformed condition. The suction bulb is removably mounted to the liquid tube, and a pair of sealing rings are located toward the rearward end of the liquid tube. The suction bulb includes internal grooves which receive and mate with the sealing rings. The forward end of the suction bulb engages a shoulder defined by a stop ring formed on the liquid tube. This structure provides a fluid-tight seal between the liquid tube and the suction bulb, to prevent leakage of air or other fluid during use.

    摘要翻译： 一种或者类似的装置包括液体管和可挤压的弹性抽吸灯泡。 抽吸灯泡包括围绕其外表面的一系列径向隔开的扇贝或凹槽，其在夹紧抽吸灯泡时提供符合人体工程学的优点。 此外，凹口之间的间隔限定了一系列平台，其用于将吸入泡沫偏压到其未变形的状态。 抽吸灯泡可拆卸地安装在液体管上，一对密封环位于液体管的后端。 抽吸灯泡包括接收和与密封环配合的内部凹槽。 吸入灯泡的前端接合由形成在液体管上的止动环限定的肩部。 这种结构在液体管和抽吸灯泡之间提供流体密封的密封，以防止在使用过程中空气或其它流体的泄漏。
