    • A disk-based fluid sample separation device including at least one air vent forming a part of a flow channel pattern on a microfluidic disk is disclosed. The fluid sample separation device is provided with an air vent sealing cover having at least through hole and is placed on the top surface of the disk. The air vent sealing cover is rotated with respect to the disk either at a first position or a second position. At the first position, the hole of the air vent sealing cover is in correspondence to the air vent of the flow channel pattern to control the sample liquid delivery. At the second position, the air vent of the flow channel pattern is closed. The flow channel pattern includes at least one sample storage reservoir, at least one sample processing reservoir, and at least one communication channel which is in fluid communication between the sample storage reservoir and the sample processing reservoir. In alternative, the status of the hole of the air vent sealing cover is controlled by a control unit.
    • 公开了一种基于盘的流体样品分离装置,其包括在微流体盘上形成流路图案的一部分的至少一个排气口。 流体样品分离装置设置有至少具有通孔的排气密封盖,并且放置在盘的顶表面上。 排气密封盖在第一位置或第二位置处相对于盘旋转。 在第一位置,排气孔密封盖的孔对应于流动通道图案的排气口,以控制样品液体输送。 在第二位置,流路图案的排气口关闭。 流动通道图案包括至少一个样品储存储存器,至少一个样品处理储存器以及在样品储存储存器和样品处理储存器之间流体连通的至少一个通信通道。 另外,排气密封盖的孔的状态由控制单元控制。

    • Disclosed is a method for separating immunomagnetic bead labeled particulates. A carrier board is formed with at least one flow channel structure, which includes an inner reservoir, an outer reservoir, and at least one micro flow channel in communication with the inner reservoir and the outer reservoir. The method includes labeling target particulates with immunomagnetic bead, introducing a sample fluid into the inner reservoir, and applying a magnetic force and a driving force, wherein the driving force drives the particulates not labeled with immunomagnetic bead to flow through the micro flow channel to the outer reservoir, while the magnetic force attracts the particulates labeled with the immunomagnetic bead to retain in the inner reservoir. The driving force may be centrifugal force, pressure, or surface tension.
    • 公开了分离免疫磁珠标记的微粒的方法。 载体板形成有至少一个流动通道结构,其包括内部储存器,外部储存器和与内部储存器和外部储存器连通的至少一个微流动通道。 该方法包括用免疫磁珠标记目标颗粒,将样品流体引入内部储存器中,以及施加磁力和驱动力,其中驱动力驱动未标记有免疫磁珠的微粒流过微流通道至 外部储存器,而磁力吸引用免疫磁珠标记的微粒保留在内部储存器中。 驱动力可以是离心力,压力或表面张力。
