Claim 3:
4. The blood analyzer according to claim 2, said blood analyzer further comprising a cleaning pipeline, wherein
a first end of the cleaning pipeline connects to the transfer pipeline and the testing sample outlet of the reaction cell, and a second end of the cleaning pipeline connects to a waste collecting apparatus, and the cleaning pipeline has a second controllable valve for controlling “on-off” of the cleaning pipeline;
the control device couples to the first controllable valve and the second controllable valve respectively, which controls the syringe to transfer the part of the first testing sample which is prepared by the blood sample and the first reagent from the reaction cell to the detection apparatus after the reaction between the blood sample and the first reagent is finished, controls the first controllable valve as “on” and the second controllable valve as “off” during the drawing of the part of the first testing sample, and controls the first controllable valve off and the second controllable valve as “off” after the part of the first testing sample is drawn;
the control device controls the first controllable valve as “off” and the second controllable valve as “on” after the leukocyte classification detection is finished, and controls the syringe to draw a cleaning solution to clean the transfer pipeline and the detection apparatus and discharge the cleaning solution from the cleaning pipeline;
the control device controls the first controllable valve as “on” and the second controllable valve as “off” after both the cleaning and the reaction between the remainder of the first testing sample and the second reagent are finished, and controls the syringe to transfer a part of the second testing sample through the transfer pipeline from the reaction cell to the detection apparatus; and
the control device controls the first controllable valve as “off” and the second controllable valve as “off” after the part of the second testing sample is drawn.
