    Abstract: The invention relates to a fluidic device (1) having a particle trap functionality for a particle (2) in a fluid, the fluidic device (1) comprising a first fluid flow channel (11), a second fluid flow channel (12), and a control channel (13), wherein the first fluid flow channel (11) is in fluid contact with the second fluid flow channel (12) and intersects the second fluid flow channel (12) at an intersection (14), wherein the control channel (13) at the location of the intersection (14) is arranged adjacent to the first fluid flow channel (11) and separated by a flexible membrane (17) from the intersection (14), wherein the flexible membrane (17) is configured as a valve (31), configured in operation at a first pressure in the control channel (13) in a first position not to block propagation of a particle (2) of a predetermined size in the first fluid flow channel (11), and at a second pressure in the control channel (13) in a second position to block with said flexible membrane (17) propagation of said particle (2) through the first fluid flow channel (11), while in this second position not fully blocking fluid flow through the first fluid flow channel (11) wherein the valve (31) is configured to provide in said second position a gradual increasing blockade of a cross sectional area (19) of the first fluid flow channel (11) in a direction parallel to a longitudinal axis of the first fluid flow channel (11).

    Abstract translation: 本发明涉及一种具有用于流体中的颗粒(2)的颗粒捕集功能的流体装置(1),该流体装置(1)包括第一流体流动通道(11),第二流体流动通道(12) 和控制通道(13),其中所述第一流体流动通道(11)与所述第二流体流动通道(12)流体接触并且在交叉点(14)处与所述第二流体流动通道(12)相交,其中所述控制 在交叉点(14)的位置处的通道(13)布置成与第一流体流动通道(11)相邻并且由柔性膜(17)与交叉点(14)分离,其中柔性膜(17)被配置 作为阀(31),其在第一位置中以控制通道(13)中的第一压力操作而不在第一流体通道(11)中阻挡预定尺寸的颗粒(2)的传播的第一位置,以及 在所述控制通道(13)中的第二压力处于与所述柔性膜(17)阻挡的第二位置, 所述颗粒(2)通过第一流体流动通道(11)的传播,而在该第二位置,不完全阻止流过第一流体流动通道(11)的流体,其中阀(31)构造成提供在所述第二位置 第一流体流动通道(11)的横截面积(19)在平行于第一流体流动通道(11)的纵向轴线的方向上逐渐增加。
