Reagent preparation apparatus and specimen processing system

A reagent preparation apparatus for preparing a predetermined reagent, the reagent preparation apparatus comprising:

• preparing means for preparing the predetermined reagent using a first liquid and a second liquid;
• supply means for supplying the predetermined reagent prepared by the preparing means to a measurement means for measuring a specimen with the predetermined reagent, the supplying means being in communication with the preparing means and the measurement means;
• acquiring means for acquiring reagent information related to the predetermined reagent, the acquiring means being in communication with the preparing means and the supply means;
• means for determining supply time information comprising a time zone having a possibility that the predetermined reagent was supplied to the measurement means on the basis of a plurality of reagent preparation dates including when the predetermined reagent passed through the acquiring means between the preparing means and the supply means;
• and
• means for outputting the reagent information and the supply time information.

A specimen processing system comprising:

• a measurement portion configured to measure a specimen with a predetermined reagent;
• a stirring chamber configured to prepare the predetermined reagent using a first liquid and a second liquid different from the first liquid;
• a supply chamber in fluid communication with the stirring chamber and the measurement portion, the stirring chamber being configured to supply the predetermined reagent to the supply chamber, the supply chamber being configured to store the predetermined reagent supplied by the stirring chamber and to supply the predetermined reagent to the measurement portion;
• a sensor provided in a flow path between the stirring chamber and the supply chamber, the sensor being in fluid communication with the stirring chamber and the supply chamber, the sensor being configured to measure a property of the predetermined reagent prepared by the stirring chamber to obtain reagent information of the predetermined reagent;
• and
• a control portion comprising a processor programmed to:
• receive the reagent information from the sensor in electrical communication with the processor,
• determine supply time information comprising a time zone having a possibility that the predetermined reagent was supplied to the measurement portion on the basis of a plurality of reagent preparation dates including when the predetermined reagent passed through the sensor provided in the flow path between the stirring chamber and the supply chamber, and
• output the reagent information and the supply time information.
