    • A micro fluidic device which comprises two or more micro channel structures (201.301) (set 1), each of which comprises a structural unit which comprises (i) one or more inlet microconduits (102,103,202,203, 302,303), and (ii) an outlet microconduit (105,205,305) downstream said one or more inlet microconduits, and (iii) a flow path for a liquid passing through either of said inlet microconduits and said outlet microconduit. The device is characterized in that each outlet microconduit (105,305) in said two or more microchannel structures (201,301) is a restriction microconduit (105,205,305). There may also be a microcavity between the inlet microconduit(s) and the restriction micro conduit in each microchanel structure. Typically common flow control is used for driving a liquid flow within the device. The innovative design is useful for creating flow with low inter-channel variation with respect 15 to the microchannel structures of the device.
    • 一种微流体装置,其包括两个或更多个微通道结构(201.301)(组1),每个微流体结构包括结构单元,其包括(i)一个或多个入口微管(102,103,202,203,302,303)和(ii)出口微管 (105,205,305)下游的一个或多个入口微管,以及(iii)通过所述入口微管和所述出口微管之一的液体的流路。 该装置的特征在于,所述两个或多个微通道结构(201,301)中的每个出口微管(105,305)是限制性微管(105,205,305)。 在每个微型结构中的入口微管和限制性微导管之间也可能存在微腔。 通常,通常的流量控制用于驱动装置内的液体流。 创新设计对于创建具有相对于设备的微通道结构相对于15的低通道间变化的流动是有用的。
