  • Patent number: 11389803
    Abstract: Disclosed is a liquid sending method for sending liquid to a sample processing chip having a flow path formed therein, the method including: measuring a flow of a second liquid which is different from a first liquid which is introduced into the flow path in the sample processing chip; controlling the flow of the second liquid on the basis of the measured flow; and introducing the first liquid into the flow path in the sample processing chip by means of the second liquid of which flow is controlled.

  • Patent number: 11325120
    Abstract: This specimen treatment chip includes: a first fluid module having a first flow channel for performing a first treatment step on an object component in a specimen; a second fluid module having a second flow channel for performing a second treatment step on the object component subjected to the first treatment step; a substrate; and a connection flow channel for connecting the first fluid module and the second fluid module disposed on the substrate.

  • Patent number: 10620108
    Abstract: Disclosed is a method of processing a specimen in which a target component in a specimen is processed using a specimen processing chip provided with a flow-path, the method including: introducing a fluid into a flow-path to form an interface that divides the fluid from a process liquid used for the processing of the target component with a rim of the interface on an inner wall of the flow-path, the process liquid containing particles including the target component; and moving the formed interface along the flow-path with the rim of the interface on the inner wall so as to force out the particles retained in the process liquid by the fluid.

  • Publication number: 20190285520
    Abstract: A sample processing method comprises storing a processing liquid (11) containing a target component (10) and a diluent (12) for diluting the processing liquid (11) in a reservoir (110) of a sample processing chip (100), and agitating the processing liquid (11) and the diluent (12) in the reservoir (110) by introducing a gas into the reservoir (110). The processing liquid (11) is diluted in order to prepare a droplet forming sample (13) for forming droplets (14) individually encapsulating the target component (10).

  • Publication number: 20180221881
    Abstract: The present specimen treatment chip includes: a first flow channel for forming a droplet containing a mixed liquid of a nucleic acid, a reagent for an amplification reaction of the nucleic acid, and a carrier to which a primer for binding to the nucleic acid is added, in a dispersion medium; a second flow channel for amplifying the nucleic acid in the droplet; and a third flow channel for mixing the droplet containing the carrier with the primer having bound to an amplification product of the nucleic acid, and a reagent for breaking down the droplet, to break down the droplet.
