摘要： The invention relates to and provides a microfluidic mixer, formed by two parts, a first part being a substrate 30 having formations defining fluid channels on an outer surface that is directed towards a second part, which is a flexible layer 20, wherein the flexile layer has formations defining fluid channel which, when the flexible layer is positioned over the substrate so as to cover the fluid channels of the substrate to provide a fluid communication path, wherein a section of said communication path comprises at least a first and a second fluid channel 1, 2 for providing a first and a second fluid, wherein first and second fluid channel merge before an inlet 9 of a mixing chamber 10 into a merged fluid channel 5, wherein the mixing chamber comprises perturbation formations 12, and an outlet 11 of the mixing chamber is connected to an outlet fluid channel 13, wherein the flexible layer comprises points for compression at the inlet and outlet of the mixing chamber for closing the merged fluid channel and the outlet fluid channel connected to inlet and outlet of the mixing chamber, characterised in that the perturbation formations of the mixing chamber are vertically arranged walls, pillars, or tubes with respect to an inner surface.

摘要： A micro fluidic flow controller comprises a substrate having formations defining two or more fluid channels having channel fluid ports which are open at an outer surface of the substrate; and a flexible layer having formations defining a fluid channel which, when the flexible layer is positioned over the substrate so as to cover at least the channel fluid ports, provides a fluid communication path between the channel fluid ports but which, when a force is applied to press the flexible layer towards the substrate, deforms so as to inhibit fluid communication between the channel fluid ports.

摘要翻译： 微流体流量控制器包括具有限定两个或更多个流体通道的构造的基底，所述流体通道具有在基底的外表面处开放的通道流体端口; 以及柔性层，其具有限定流体通道的构造，当柔性层定位在基底上方以至少覆盖通道流体端口时，柔性层提供通道流体端口之间的流体连通路径，但是当施加力时 将柔性层朝衬底按压，从而变形以抑制通道流体端口之间的流体连通。
