Specific embodiment
The present invention is elaborated with reference to Figure of description:
Embodiment, as shown in figure 1, blood cell analyzer strength cleaning solution automatic filling device of the present invention includes：Malleation
Pump 1, balancing gate pit 2, gas pressure sensor 3, strength cleaning solution bottle 4, level sensing optocoupler 5, flow chamber outlet 9, DIFF passages
Sample entrance port 6, DIFF reaction tanks 11, sampling needle 12, sampling needle motion 13, sampling syringe 14, motor 16, WBC is counted
Pond 17, RBC counting chambers 18, two three-way electromagnetic valve V1, two three-way electromagnetic valve V2, pinch valve PV1, barrier film check valve 7, three-way connection 8, three
Pass joint 10.In blood cell analyzer strength cleaning solution automatic filling device, positive pressure pump 1, gas pressure sensor 3, two lead to
Magnetic valve V1 is connected by pipeline with balancing gate pit 2 respectively.Positive pressure pump 1 is used for setting up pressure, and gas pressure sensor 3 is used for monitoring
Pump builds the pressure value of pressure.Two three-way electromagnetic valve V1 are connected by pipeline with the bottle cap joint A of strength cleaning solution bottle 4.Strength cleaning solution bottle 4
Bottle cap joint B the one end of barrier film check valve 7 is connected to by pipeline, a level sensing on the close bottle cap end set of this section of pipeline
This section of pipeline, is entered pinch valve PV1 normal-closed ends by optocoupler 5 near the side pressure of barrier film check valve 7.The other end of barrier film check valve 7 connection three
Pass joint 8, the one end of three-way connection 8 connection flow chamber outlet 9, sets two three-way electromagnetic valve V2 in intermediate duct, three-way connection 8 is another
End connection three-way connection 10.The one end of three-way connection 10 connects through the normally opened ends of pinch valve PV1 with DIFF channel samples entrance 6, threeway
The other end of joint 10 is connected with DIFF reaction tanks 11.Sampling needle 12 is fixed on sampling needle motion 13, needle movement of sampling
Mechanism 13 can be such that sampling needle 12 makees vertically as well as horizontally, and sampling needle 12 is connected by pipeline with sampling syringe 14, sampling note
Emitter 14 is driven by motor 16, and dilution entrance 15 is provided with sampling syringe 14.Connection=gas in balancing gate pit 2
Pressure sensor 3, in the pressure value built in the pressure time in real-time monitoring system of regulation, when the pressure value in system reaches setting
Target after, system will stop building pressure immediately, when build pressure the time period in pressure value be less than sets target value after, system meeting again
It is immediately performed to build and presses work, if pressure value is consistently less than certain value of setting, illustrates to build and press unsuccessful, the system failure is reported at once
Alert prompting.A level sensing optocoupler 5 is socketed on the pipeline of bottle cap end B on the drain pipe road of strength cleaning solution bottle 4, when in pipe
When having liquid and no liquid, the voltage signal of optocoupler receiving terminal is different, and strength cleaning solution bottle is monitored using the principle
Inside whether there is liquid, it's not true will point out user to change.Pinch valve PV1 and three is connected on strength cleaning solution export pipeline
A barrier film check valve 7 is concatenated between first 8.When pinch valve PV1 can go up electricity when leukocyte differential count pushes away sheath stream, then strongly
The normal-closed end that cleaning solution export pipeline is pressed into pinch valve PV1 will be opened, and such three-way connection 8 connects to strength cleaning solution bottle 4
Lead to, the waste liquids for having flow chamber outlet 9 to release pour in down a chimney the risk into strength cleaning solution bottle 4, and one barrier film check valve 7 of concatenation is just
The problem can be solved.It is pressed into DIFF reaction tanks 11 in whole process in bottle 4 in strength cleaning solution, strength cleaning solution is obstructed
Cross inside magnetic valve, in the absence of corrosion magnetic valve problem, and under not use state cleaning solution bottle two ends be all it is closed, also not
There is a problem of volatile zone.
Blood cell analyzer strength cleaning solution automatic filling device, its charging method comprises the following steps：
The step of the mat woven of fine bamboo strips one empties pipeline and pond liquid, is counted DIFF reaction tanks 11, WBC using the original emptier of blood analyser
Number pond 17, RBC counting chambers 18 are emptied from each waste liquid outlet.Emptying common pall be using the original device of blood analyser from
Suction is until the pipe evacuation being connected with DIFF reaction tanks 11 and three-way connection 10 at DIFF channel samples entrance 6, it is therefore an objective to allow
Strength cleaning solution is not diluted when flowing through this section of common pall by liquid in pipe.
The step pressure injection of the mat woven of fine bamboo strips two and distribution strength cleaning solution, open two three-way electromagnetic valve V1, while opening positive pressure pump 1 in the stipulated time
It is interior to carrying out building malleation in balancing gate pit 2 and strength cleaning solution bottle 4, the monitoring pressure in real time value of gas pressure sensor 3 sets when reaching
Stop building pressure after the pressure value that sets the goal.The size of target pressure value is according to strength cleaning solution bottle 4 to this section knot of DIFF reaction tanks 11
Depending on the flow resistance of structure and the liquid measure of needs filling.To the pressure injection strength cleaning solution of DIFF reaction tanks 11, build after pressing and open pinch valve
PV1 so that strength cleaning liquid pipeline is communicated with DIFF reaction tanks 11, and strength cleaning solution is from bottle cap joint B under the driving of pressure
Flow into DIFF reaction tanks 11.Electric opening time is according to positive pressure pressure size and depending on need to filling liquid measure on pinch valve PV1.Strength is clear
The distribution of clean liquid, by strength cleaning solution pressure injection to DIFF reaction tanks 11 after, sampling needle motion 13 moves sampling needle level 12
Vertically move to the top of DIFF reaction tanks 11 and then again and make sampling needle stretch into DIFF reaction tanks 11 to drive injection by motor 16
Device 14 draws quantitative strength cleaning solution, then go up again level, move vertically to WBC counting chamber 17/RBC counting chambers 18 in will be strong
In power cleaning solution injection pond.
The step of the mat woven of fine bamboo strips three is soaked, and the desired amount of strength cleaning solution is all added in DIFF reaction tanks, WBC counting chambers, RBC counting chambers
Afterwards, the strength cleaning solution in pond is diluted with blood analyser original part, then conveys the cleaning solution after dilution
To the immersion of each position of analyzer.
When the total consumption of strength cleaning solution needed for three ponds more than a pressure injection to liquid measure in DIFF reaction tanks when, can
To repeat second step.
