    • The present invention is a robust, microfluidic check valve and a method of using the check valve in microfluidic devices. The check valve is comprised two stacked chambers that are separated by a pore-containing membrane. The membrane is composed of an elastomeric material and can be configured in normally open or normally closed state. The normally open check valve can be implemented so that the degree of back pressure necessary to close the valve can be set. The normally closed embodiment can maintain a closed state with essentially no back pressure. Both the normally open and the normally closed version can be readily produced by multilayer soft lithographic techniques and may retain effective functioning through many thousands of opening and closing cycles without failure. Such check valves can substitute for active valve structures in microfluidic devices and, when appropriately implemented, can simplify the design, manufacture, and/or operation of the devices containing them.
    • 本发明是一种坚固的微流体止回阀和在微流体装置中使用止回阀的方法。 止回阀包括由含孔膜隔开的两个堆叠室。 膜由弹性体材料构成,并且可以构造成常开或常闭状态。 可以实现常开止回阀,使得可以设定关闭阀所需的背压程度。 常闭实施例可以保持基本上没有背压的关闭状态。 常开和常闭型都可以通过多层软平版印刷技术轻松生产,并可通过数千个开闭周期保持有效的功能,而不会发生故障。 这种止回阀可以替代微流体装置中的主动阀结构,并且当适当实施时,可以简化包含它们的装置的设计,制造和/或操作。
