Automatic analyzing apparatus
According to one embodiment, an automatic analyzing apparatus includes a reagent depository, a reagent storage unit and a probe. The reagent depository stores a first reagent vessel. The reagent storage unit is provided separately from the reagent depository and in which a second reagent vessel is placeable. The probe suctions a reagent contained in the first reagent vessel at a first position which is located above the reagent depository, suctions a reagent contained in the second reagent vessel at a second position which is located above the reagent storage unit, and discharges the reagent suctioned from the first reagent vessel or the second reagent vessel into a reaction vessel at a third position.
1. An apparatus, comprising:
a reagent depository that stores a first reagent vessel;
a reagent storage unit that is provided separately from the reagent depository and in which a second reagent vessel is placeable;
a probe that (a) suctions, from a first position which is located above the reagent depository, a first reagent contained in the first reagent vessel; (b) suctions, from a second position which is located above the reagent storage unit, a second reagent contained in the second reagent vessel; and (c) discharges the respective first or second reagent suctioned from the first reagent vessel or the second reagent vessel into a reaction vessel at a third position;
a measurement unit that measures a solution mixture of an object test sample and a reagent to generate object data;
a reader that reads reagent information indicated on the second reagent vessel placed in the reagent storage unit; and
analysis controlling circuitry configured to (a) cause the probe to suction a reagent from the second reagent vessel after the reagent information is read by the reader when (1) an amount of a reagent of a test item in the first reagent vessel stored in the reagent depository reaches below a predetermined amount and (2) the second reagent vessel contains a reagent of a test item that is the same as the test item of the first reagent vessel stored in the reagent depository, (b) cause the reader to read the reagent information indicated on the second reagent vessel when the second reagent vessel containing a predetermined reagent is placed once again in the reagent storage unit after being removed therefrom, and (c) cause the measurement unit to measure the solution mixture of the object test sample and the reagent when the reagent in the second reagent vessel from which the reagent information is read by the reader is the predetermined reagent,
wherein
the reagent storage unit includes an intake port arranged below the probe,
the reagent storage unit intakes the second reagent vessel horizontally through the intake port, and
the second reagent vessel is placed in the reagent storage unit.
2. The apparatus according to claim 1 , further comprising an arm that supports the probe so that the probe is moved along a first track between the first position and the third position, and a second track between the second position and the third position.
3. The apparatus according to claim 2 , wherein
the first track and the second track are arc-shaped tracks sharing a same circumference.
4. The apparatus according to claim 1 , wherein
the reagent storage unit has a cover that covers an upper portion of the second reagent vessel placed in the reagent storage unit, and
the cover includes a penetrating hole at a position corresponding to the second position.
5. The apparatus according to claim 1 , wherein
the reagent depository stores a plurality of first reagent vessels, and
the reagent storage unit includes a reader that reads reagent information indicated on the second reagent vessel placed in the reagent storage unit by being horizontally pushed in through the intake port,
the analysis controlling circuitry is further configured to cause the probe to suction a reagent in the second reagent vessel when the second reagent vessel containing a reagent different from any of reagents contained in all the first reagent vessels stored in the reagent depository is placed in the reagent storage unit.
6. The apparatus according to claim 1 , wherein
the second reagent vessels can be placed in the reagent storage unit,
the number of the second reagent vessels placed in the reagent storage unit is less than the number of the first reagent vessels that the reagent depository is capable of storing.
7. The apparatus according to claim 1 , wherein
the reagent includes a first reagent contained in a third reagent vessel, and a second reagent which constitutes a pair with the first reagent contained in the fourth reagent vessel,
the apparatus further comprising analysis controlling circuitry configured to generate an error message if either one of the third reagent vessel or the fourth reagent vessel is placed in the reagent storage unit, and another reagent vessel is neither stored in the reagent depository nor placed in the reagent storage unit.
8. The apparatus according to claim 1 , wherein the reagent storage unit has a cover that covers an upper portion of the second reagent vessel placed in the reagent storage unit, and
wherein the reagent storage unit comprises a placement surface where the second reagent vessel is placeable, a first side surface, a second side surface, a third side surface, and the cover.
