Abstract
In a pretreatment apparatus for transferring and mixing a specimen liquid and a reagent in a reagent reservoir, comprising containers for holding the specimen liquid and the reagent, flow paths connecting the containers in series, and a dialysis flow path including a dialysis membrane facing to the flow path, the mixing is brought about by transferring the liquid from the containers to the flow paths and a return by stoppage of transferring the liquid, and subsequently the liquid is made flow into the dialysis flow path.
Claims17
A pretreatment apparatus for transferring and mixing a specimen liquid and a reagent in a reagent reservoir, comprising containers for holding the specimen liquid and the reagent, flow paths connecting the containers in series, and a dialysis flow path including a dialysis membrane facing to the flow path, wherein the mixing is brought about by transferring the liquid from the containers to the flow paths and a return by stoppage of transferring the liquid, and subsequently the liquid is made flow into the dialysis flow path.
A pretreatment apparatus for transferring a specimen liquid and a reagent so that the specimen liquid and the reagent are mixed with each other, comprising:
- a first container for receiving the specimen liquid and the reagent,
- a second container for receiving a mixture of the specimen liquid and the reagent,
- a flow path extending between the first and second containers to be fluidly communicated with each other, and
- a pressure apply port fluidly connected to one of the first and second containers to supply a gaseous matter into the one of the first and second containers and to discharge the gaseous matter from the one of the first and second containers so that a pressure in the one of the first and second containers is differentiated from a pressure in the other one of the first and second containers to make the specimen liquid and the reagent flow in at least a part of the flow path.
