Because syringe is acted by the completion discharge opeing action of push-and-pull piston and imbibition, therefore its discharge opeing action and suction
Surge and be unable to simultaneously perform, unlike liquid pump can one side imbibition one side discharge opeing, and when stirring and washing pond 3,
When the cleaning device 71 of sample reagent service sink 5 and the 3rd shares same syringe, it is meant that in a work week
In phase, imbibition should be completed, is completed again to stirring and washing pond 3, the cleaning of sample reagent service sink 5 and the 3rd
At least three times discharge opeings of device 71, the capacity of syringe is bigger, and the supported discharge opeing number of times of an imbibition is more,
But when sample analyser complete machine is minimized, it is usually desirable to use the small volume syringes less than 20ml, such as
The volume of syringe is 10ml, and small syringe cost is also low, but adds the complexity of control sequential.Separately
Outside, because stirring and washing pond 3, sample reagent service sink 5 are different with the structure of the 3rd cleaning device 71, hold
Amount is different, cleaning way is different, therefore the flow of the rinse water of their required injections and time are also different,
This again increases the complexity of syringe control sequential.For agitating device, dispenser and reaction cup is clear
Wash clean, the present invention has formulated following cleaning rule：
Within a work period, reaction tray rotated within a work period and stop it is at least each twice,
Dispensing cleaning and stirring and washing are performed when reacting disc spins, reaction cup cleaning is performed during reaction tray stops.
Within a work period, controller controls the first pumping equipment to perform three imbibitions action, and at least four times most
Many six discharge opeings actions；The liquid absorption of first time is more than or equal to first time imbibition to total between second of imbibition
The greater of lifting rate and second of imbibition into total lifting rate between third time imbibition；Secondary imbibition
Amount is more than or equal to first time imbibition to total lifting rate between second of imbibition；The liquid absorption of third time be more than etc.
In third time imbibition to total lifting rate between the first time imbibition of subsequent work cycle.
The cleaning sequential of the present embodiment described further below.
When there is sample dispensing, reagent dispensing, dispensing cleaning, stirring and washing and reaction in a work period
During cup cleaning, its control sequential meets following condition：

Embodiment two：
In the present embodiment, controller controls the first pumping equipment to be filled respectively to the first cleaning device and the 3rd cleaning
Put injection rinse water, i.e. the first cleaning device and the 3rd cleaning device shares the first pumping equipment.
Fig. 7 is refer to, the first pumping equipment 9 is syringe, and the 3rd pumping equipment 15 is liquid pump, first row
Liquid device 9 passes through the first pipeline selecting switch 8 and sample reagent service sink 5, the 3rd cleaning device 71 and Sheng
Water receptacle 10 is controllably connected, and the 3rd pumping equipment 15 passes through the second pipeline selecting switch 17 and dispenser
6 controllably connect with stirring and washing pond 3.Controller respectively with the first pipeline selecting switch 13 and the second pipeline
Selecting switch 17 is electrically connected, when controller controls the alteration switch state of the first pipeline selecting switch 13, by the
When one pumping equipment is connected with water container, the first pumping equipment of control draws rinse water from water container, when
Controller controls the first pipeline selecting switch alteration switch state, by the first pumping equipment and the first cleaning device
Or during the 3rd cleaning device connection, control the first pumping equipment discharge rinse water.When controller control second is managed
The alteration switch state of road selecting switch 17, makes the 3rd pumping equipment be filled by the second pipeline selecting switch and dispensing
When putting connection, rinse water is provided for the inner wall washing of dispenser；When controller controls the selection of the second pipeline to open
17 alteration switch states are closed, the 3rd pumping equipment is connected by the second pipeline selecting switch and stirring and washing pond 3
It is that stirring and washing pond 3 provides rinse water when logical.
There is sample dispensing, reagent dispensing in a work period, divide in its control sequential as shown in figure 8, working as
When note cleaning, stirring and washing and reaction cup cleaning, controller control reaction tray rotates within a work period
Twice with stopping twice, when reaction tray rotates for the first time, controller controls the first pumping equipment and dispensing dress
Put the dispensing cleaning of execution first time；During reaction tray stops for the first time, controller controls the first pumping equipment
Suction rinse water for the first time is performed, and controls the 3rd pumping equipment and agitating device to perform first time stirring and washing,
Sample is dispensed into reaction cup by control dispenser；When reaction tray rotates for the second time, controller control the
One pumping equipment and dispenser perform second of dispensing cleaning；When reaction tray stops for the second time, controller
Reagent is dispensed into reaction cup by control dispenser, and the first pumping equipment of control and the 3rd cleaning device are performed
Reaction cup is cleaned twice, and controls the execution between the cleaning of reaction cup twice of the first pumping equipment to suck for the second time
Rinse water.
In the present embodiment, the 3rd pumping equipment 15 uses liquid pump, and its control sequential is relatively easy, but improves
The flow of second pipeline selecting switch 17, that is, improve the cost of the second pipeline selecting switch 17.Other
In embodiment, the 3rd pumping equipment 15 can also use syringe, but can increase the complexity of control sequential.
Water syringe is cleaned using 10ml in above-described embodiment, in other embodiments, it is also contemplated that using
The bigger syringe of range, so can then carry out the cleaning of more number of times within a work period.But
The big syringe cost of range is larger, and fault rate is also higher.
In above-described embodiment, the first pumping equipment can also use liquid pump, in this case can simplify control when
Sequence, but the cleaning based on dispenser, the cleaning of agitating device and the required flow of reaction cup cleaning are different,
And liquid pump is a kind of device of firm discharge, therefore required when selecting liquid pump with regard to maximum stream flow selection, and
Flow means that more greatly the volume of liquid pump is bigger, cost is higher.
The work period refers to from the operation of a upper reagent dispensing to the operation of next reagent dispensing in above-described embodiment
Time interval.For a person skilled in the art, the period can be adjusted defined in the work period,
So as to which sample dispenser, rabbling mechanism, wiper mechanism, cleaning water syringe, cleaning agent relative can be adjusted
The sequencing of syringe.
Within the work period as described herein, for those skilled in the art, sample point can be adjusted
Cleaning sequencing between dispensing device, rabbling mechanism and wiper mechanism, or increase sample dispenser,
The wash number of rabbling mechanism, wiper mechanism, or reduce sample dispenser, rabbling mechanism, cleaning machine
The wash number of structure, therefore can relative adjustment cleaning water syringe, the suction volume of flush syringe and elder generation
Afterwards sequentially.
Above-mentioned pipeline selecting switch 8,13,16,17, can be by using one or more electronics valve group
Close and constitute.
Use above specific case is illustrated to the present invention, is only intended to help and is understood the present invention, not
To limit the present invention.For those skilled in the art, according to the thought of the present invention,
Some simple deductions, deformation can also be made or replaced.
