The waste unit 7 further includes multiple waste solution channels 74, and the multiple waste solution channel 74 is connected to described take Sample unit 2 divides between the liquid outlet and waste liquid pool above-mentioned of blood valve 3, reaction member 4 and the detection unit 5, and for leading The waste liquid that the sample analyser 100 generates out；It is three groups, one group and first waste liquid pool that the multiple waste solution channel 74, which divides, 71 connect, and one group connects with second waste liquid pool 72, and one group connects with the third waste liquid pool 73.It is described in the present embodiment First waste liquid pool 71 connects the waste liquid that the sampling unit 2 generates；Second waste liquid pool 72 connects HGB reaction tank 42 respectively And waste liquid, institute caused by the HGB waste liquid, RBC premixing pool 43 and the RBC test section 53 that are generated with test section 52 State the cleaning waste liquid that WBC test section 51 generates and the waste liquid that the WBC reaction tank 41 generates；The third waste liquid pool 73 The detection waste liquid and the waste liquid for dividing blood valve 3 to generate that the WBC test section 51 generates are connect respectively, wherein the WBC inspection The detection waste liquid in survey portion 51 can not need external pressure under the thrust of FCM sheath fluid and collect in the third waste liquid pool 73.Separately Outside, first waste liquid pool 71 is also used to connect the waste liquid for dividing blood valve 3 and the WBC reaction tank 41 to generate.Described first Waste liquid pool 71 is also connected to liquid storage tank in a few machine, in the state of accessing the negative pressure of the gas circuit unit 8, Xiang Suoshu to be at least Liquid storage tank provides negative pressure in one machine, and liquid storage tank at least one described machine is made to draw reagent from outside machine.

As shown in figure 15, in the present embodiment, liquid storage tank 611 in the LD hemolytic agent machine, liquid storage tank in LN hemolytic agent machine 612, liquid storage tank 621 connects with first waste liquid pool 71 in liquid storage tank 613 and the DR dilution machine in LH hemolytic agent machine, It is drawn in the state of accessing the negative pressure of the gas circuit unit 8, be used for the reagent barrel from outside machine in first waste liquid pool 71 Reagent；In the state of with the disconnection of the negative pressure of the gas circuit unit 8, liquid storage tank is closed liquid storage tank in above-mentioned machine, in above-mentioned machine When supplying reagent, the consumption of reagent makes in the machine to form negative pressure in liquid storage tank liquid storage tank, so that liquid storage tank is also in above-mentioned machine It can be used for automatically that reagent barrel draws reagent to supplement the reagent of consumption from outside machine.In other embodiments, it can also will be stored up in machine Liquid pool access accesses the negative pressure of the gas circuit unit and carries out supply reagent with the imbibition from outside machine, and access positive pressure or atmosphere.It can be with Understand, because second waste liquid pool 72 can also access negative pressure, therefore, in other embodiments, liquid storage in the LD hemolytic agent machine Liquid storage tank 612 in pond 611, LN hemolytic agent machine, liquid storage tank 621 in liquid storage tank 613 and the DR dilution machine in LH hemolytic agent machine It can also connect with second waste liquid pool 72.

Liquid storage tank 611 in the LD hemolytic agent machine, liquid storage tank 612 in LN hemolytic agent machine, liquid storage tank 613 in LH hemolytic agent machine And the first control valve 75 is connected in the DR dilution machine between liquid storage tank 621 and the gas circuit unit 8, first control Valve 75 is for controlling liquid storage tank 611 in the LD hemolytic agent machine, liquid storage tank 612 in LN hemolytic agent machine, liquid storage in LH hemolytic agent machine The connection and truncation of gas circuit in pond 613 and the DR dilution machine between liquid storage tank 621 and the gas circuit unit 8；This implementation In example, liquid storage tank 611 in the LD hemolytic agent machine, liquid storage tank 612 in LN hemolytic agent machine, in LH hemolytic agent machine liquid storage tank 613 and Liquid storage tank 621 is separately connected first control valve 75 in the DR dilution machine, and each first control valve 75 divides Liquid storage tank 611 in the LD hemolytic agent machine, liquid storage tank 612 in LN hemolytic agent machine, liquid storage tank in LH hemolytic agent machine are not controlled individually 613 and the DR dilution machine in gas circuit between liquid storage tank 621 and the gas circuit unit 8 connection and truncation；Wherein, may be used So that liquid storage tank 613 and institute in liquid storage tank 611 in the LD hemolytic agent machine, liquid storage tank 612 in LN hemolytic agent machine, LH hemolytic agent machine Stating liquid storage tank 621 in DR dilution machine, one first control valve 75 of connection, first control valve 75 are used for simultaneously jointly Control liquid storage tank 611 in the LD hemolytic agent machine, liquid storage tank 612 in LN hemolytic agent machine, liquid storage tank 613 and institute in LH hemolytic agent machine State the connection and truncation of the gas circuit in DR dilution machine between liquid storage tank 621 and the gas circuit unit 8.

When in a machine liquid storage tank 613 under the action of constant displacement pump 616, in hemolytic agent be shifted into reaction tank supply When liquid, liquid storage tank and the outer reagent barrel of machine form the confined space of normal pressure in machine, that is, the pressure in the space is held essentially constant, machine When interior liquid storage tank feed flow, of short duration negative pressure will form in liquid storage tank, the reagent of the outer reagent barrel of the negative pressure driving machine adds in machine In buffer pool, until the liquid level of the reagent of the outer reagent barrel of machine drops to the confined space and can not be formed, when the examination of liquid storage tank in machine When agent liquid level continues to drop to low level, constant displacement pump 616 can stop transferring reagent into reaction tank, and provide and believe without reagent failure Breath.After reagent barrel is replaced outside machine, after user's point is eliminated without reagent failure, liquid storage tank in 71 connection machine of the first waste liquid pool is Negative pressure is established in machine in liquid storage tank, so that the reagent of the outer reagent barrel of machine quickly charges in machine in liquid storage tank, due to liquid storage in machine Pool volume is smaller, about 100 milliliters hereinafter, therefore can quickly complete and charge, after liquid storage tank charges full in machine, the first waste liquid pool 71 are not connected to liquid storage tank in machine, and liquid storage tank and the outer reagent barrel of machine form the confined space of normal pressure again in machine, and constant displacement pump moves again Send the reagent of liquid storage tank in machine into reaction tank, the reagent with reagent barrel outside opportunity is inhaled into supplement the reagent of consumption.

First control valve 75 can be two-way valve or triple valve, when being triple valve, for controlling liquid storage in the machine The negative pressure of the gas circuit unit 8, or the positive pressure or atmosphere of the access gas circuit unit, or truncation and the gas circuit unit are accessed in pond Connection.In the present embodiment, first control valve 75 is set on the right side plate 13, to facilitate and the waste liquid pool and institute State the connection in machine between liquid storage tank.
