Abstract

An automatic analyzer includes a transporter, a first dispensing probe, a second dispensing probe, and a control unit. The transporter transports a reaction tube for sample and a reaction tube for transfer. The first dispensing probe dispenses a mixed solution including a sample. The second dispensing probe dispenses a reagent or a diluent solution. The control unit controls the first dispensing probe so as to suck the mixed solution from the reaction tube for sample in a first cycle and discharge the mixed solution into the reaction tube for transfer in a second cycle if an amount of the mixed solution to be transferred from the reaction tube for sample to the reaction tube for transfer is greater than a threshold value.

First claim

1 . An automatic analyzer comprising:
a transporter configured to transport a reaction tube for sample and a reaction tube for transfer; a first dispensing probe configured to dispense a mixed solution including a sample; a second dispensing probe configured to dispense a reagent or a diluent solution; and a control unit configured to control the first dispensing probe so as to suck the mixed solution from the reaction tube for sample in a first cycle and to discharge the mixed solution into the reaction tube for transfer in a second cycle if an amount of the mixed solution to be transferred from the reaction tube for sample to the reaction tube for transfer is greater than a threshold value.

2 . The automatic analyzer according to claim 1 , wherein the control unit controls the first dispensing probe so as to suck the mixed solution from the reaction tube for sample and to discharge the mixed solution into the reaction tube for transfer in a single cycle if the amount of the mixed solution to be transferred from the reaction tube for sample to the reaction tube for transfer is equal to or less than the threshold value.

3 . The automatic analyzer according to claim 1 , wherein the control unit controls the second dispensing probe so as to dispense either the reagent or the diluent solution according to a user's setting.

4 . The automatic analyzer according to claim 1 , wherein the control unit controls the second dispensing probe so as to dispense either a first reagent or a second reagent according to a user's setting.

5 . The automatic analyzer according to claim 1 configured to have a function to set the threshold value for each of measurement items.

6 . The automatic analyzer according to claim 1 configured to have a function to dispense either the reagent or the diluent solution using the second dispensing probe.

7 . The automatic analyzer according to claim 1 configured to have a function to set whether a first reagent or a second reagent is dispensed using the second dispensing probe.

8 . The automatic analyzer according to claim 1 configured to have a function to set the threshold value on a settings screen for setting measurement items.

9 . The automatic analyzer according to claim 3 configured to have a function to set whether the reagent or the diluent solution is dispensed using the second dispensing probe on a measurement request screen for setting measurement items.

10 . A method for transferring a mixed solution in an automatic analyzer including:
a transporter configured to transport a reaction tube for sample and a reaction tube for transfer; a first dispensing probe configured to dispense a mixed solution including a sample; and a second dispensing probe configured to dispense a reagent or a diluent solution, the method comprising: a transferring step including: sucking the mixed solution from the reaction tube for sample in a first cycle and discharging the mixed solution into the reaction tube for transfer in a second cycle if an amount of the mixed solution to be transferred from the reaction tube for sample to the reaction tube for transfer is greater than a threshold value.

11 . The method for transferring the mixed solution in the automatic analyzer according to claim 10 , further comprising:
another transferring step including: sucking the mixed solution from the reaction tube for sample and discharging the mixed solution into the reaction tube for transfer in a single cycle if the amount of the mixed solution to be transferred from the reaction tube for sample to the reaction tube for transfer is equal to or less then the threshold value.

12 . The method for transferring the mixed solution in the automatic analyzer according to claim 10 , further comprising:
a determining step performed by a control unit included in the automatic analyzer before the transferring step, the determining step including: determining whether the amount of the mixed solution to be transferred from the reaction tube for sample to the reaction tube for transfer is greater than the threshold value.
