    • There is disclosed a microorganism testing device in which various types of microorganisms can be easily concentrated. The microorganism testing device includes a detection chip, a carrier device, a controller, and a magnet. The detection chip includes a specimen container for holding a specimen containing microorganisms, a trapping particle liquid container for holding trapping particle liquid containing magnetic particles, a microorganism trapping section for trapping the microorganisms, and a liquid flow path. In a state where a magnetic force of the magnet acts on the microorganism trapping section, the controller controls the carrier device to flow the trapping particle liquid into the microorganism trapping section to form a filtration filter by trapping plural magnetic particles in the microorganism trapping section, and in this state, to flow the microorganisms into the microorganism trapping section so that the microorganisms within the specimen are deposited on one side of the filtration filter.
    • 公开了微生物检测装置,其中可以容易地浓缩各种类型的微生物。 微生物检测装置包括检测芯片,载体装置,控制器和磁体。 检测芯片包括用于容纳含有微生物的试样的检体容器,用于保持含有磁性颗粒的捕获颗粒液体的捕获颗粒液体容器,用于捕获微生物的微生物捕获部分和液体流动路径。 在磁铁的磁力作用于微生物捕获部的状态下,控制器控制载体装置将捕获颗粒液体流入微生物捕获部分,以通过捕获微生物捕获部分中的多个磁性颗粒而形成过滤器, 并且在该状态下,将微生物流入微生物捕获部分,使得样品内的微生物沉积在过滤器的一侧。
