1. A method for introducing a specimen into a specimen treatment device, the specimen treatment device including a first inflow port and a second inflow port and being internally configured to flow a plurality of liquids between the first inflow port and the second inflow port, the method being a method for introducing a first liquid of the plurality of liquids being the specimen to be tested and a second liquid of the plurality of liquids to be compared into the first inflow port and the second inflow port of the specimen treatment device respectively, the method comprising:
by using a switching member configured to switch a liquid flow path between two inlets-and-outlets of a first inlet-and-outlet, a second inlet-and-outlet, and a third inlet-and-outlet, connecting a first feeder configured to supply the first liquid to the first inlet-and-outlet, connecting the second inlet-and-outlet to a discharge container, connecting the third inlet-and-outlet to the first inflow port of a specimen treatment device, and further connecting a second feeder configured to supply the second liquid to the second inflow port of the specimen treatment device;
enabling the switching member to flow at least one liquid of the plurality of liquids between the second inlet-and-outlet and the third inlet-and-outlet, and sending out the second liquid from the second feeder to the discharge container through the second inflow port, the specimen treatment device, the first inflow port, and the switching member to fill a second path from the second feeder to the switching member with the second liquid;
enabling the switching member to flow at least one liquid of the plurality of liquids between the first inlet-and-outlet and the second inlet-and-outlet, and sending out the first liquid from the first feeder to the discharge container through the switching member to fill a first path from the first feeder to the switching member with the first liquid; and
subsequently enabling the switching member to flow at least one liquid of the plurality of liquids between the first inlet-and-outlet and the third inlet-and-outlet, sending out the first liquid from the first feeder through the switching member to introduce the first liquid into the first inflow port, and sending out the second liquid from the second feeder to introduce the second liquid into the second inflow port.
