Reagent preparing device, reagent preparing method, and specimen processing system

A reagent preparing method of preparing a predetermined reagent, which includes a first liquid and a second liquid different from the first liquid, to be supplied to a measurement section for measuring a specimen using the reagent, comprising:

• generating pressure to transfer liquid;
• executing a preparation operation of the predetermined reagent using the generated pressure;
• determining whether or not the preparation operation is being executed;
• and
• controlling the generation of the pressure according to the determination result.

A specimen processing system comprising:

• a measurement section for measuring a specimen using a predetermined reagent, which includes a first liquid and a second liquid different from the first liquid;
• a pressure generator for generating pressure to transfer liquid;
• a reagent preparing section for executing a preparation operation of the predetermined reagent using the pressure generated by the pressure generator;
• and
• a controller configured for performing operations comprising:
• determining whether or not the reagent preparing section is executing the preparation operation, and
• controlling the generation of the pressure by the pressure generator according to the determination result.
