    • Microfluidic devices and methods for segregating aliquots of fluid from large fluid volumes are provided. Preferably, a device includes an actuating channel, a metering channel and a deformable membrane disposed therebetween. The metering channel is in fluid communication with a fluid source, but is otherwise closed. The pressure in the actuating channel may be varied to deform the deformable membrane. The volume of the metering channel varies in proportion with the deformation of the deformable membrane, creating a pressure differential between the metering channel and the fluid source that causes fluid to be drawn into or expelled from the metering channel. Magnetic or mechanical actuating means may be substituted for the actuating channel. Multiple aliquots of different liquids may be drawn into metering channels and mixed thereafter in one or many different mixing proportions.
    • 提供了用于从大流体体积分离液体等分液体的微流体装置和方法。 优选地,装置包括致动通道,计量通道和设置在其间的可变形膜。 计量通道与流体源流体连通,但是否则关闭。 可以改变致动通道中的压力以使可变形膜变形。 计量通道的体积与可变形膜的变形成比例地变化,从而在计量通道和流体源之间产生压力差,导致流体被吸入或从计量通道排出。 磁性或机械致动装置可以代替致动通道。 不同液体的多个等分试样可以被吸入计量通道中,然后以一种或多种不同的混合比例混合。

    • Robust microfluidic mixing devices mix multiple fluid streams passively, without the use of moving parts. In one embodiment, these devices contain microfluidic channels that are formed in various layers of a three-dimensional structure. Mixing may be accomplished with various manipulations of fluid flow paths and/or contacts between fluid streams. In various embodiments, structures such as channel overlaps, slits, converging/diverging regions, turns, and/or apertures may be designed into a mixing device. Mixing devices may be rapidly constructed and prototyped using a stencil construction method in which channels are cut through the entire thickness of a material layer, although other construction methods including surface micromachining techniques may be used.
    • 强大的微流体混合装置将被动地混合多个流体流,而不使用运动部件。 在一个实施例中,这些装置包含在三维结构的各个层中形成的微流体通道。 混合可以通过流体流动路径和/或流体流之间的接触的各种操作来实现。 在各种实施例中,可以将诸如通道重叠,狭缝,会聚/发散区域,匝和/或孔的结构设计成混合装置。 混合装置可以使用模板施工方法进行快速构造和原型制备,其中通道切割材料层的整个厚度,尽管可以使用包括表面微加工技术的其他构造方法。
