Embodiment

Below in conjunction with Figure of description, the utility model is elaborated:

Embodiment, as shown in Figure 1, the powerful cleaning solution automatic filling device of the utility model blood cell analyzer comprises: positive pressure pump 1, pressure chamber 2, gas pressure sensor 3, powerful cleaning solution bottle 4, level sensing optocoupler 5, flow chamber outlet 9, DIFF channel sample entrance 6, DIFF reaction tank 11, sampling needle 12, sampling needle motion 13, sampling syringe 14, motor 16, WBC counting chamber 17, RBC counting chamber 18, two three-way electromagnetic valve V1, two three-way electromagnetic valve V2, pinch valve PV1, barrier film retaining valve 7, three-way connection 8, three-way connection 10.In the powerful cleaning solution automatic filling device of blood cell analyzer, positive pressure pump 1, gas pressure sensor 3, two three-way electromagnetic valve V1 are connected with pressure chamber 2 respectively by pipeline.Positive pressure pump 1 is used for build-up pressure, and gas pressure sensor 3 is used for monitoring the force value that pressure built by pump.Two three-way electromagnetic valve V1 are communicated with powerful cleaning solution bottle 4 bottle cap joint A by pipeline.The bottle cap joint B of powerful cleaning solution bottle 4 receives barrier film retaining valve 7 one end by pipeline, and a level sensing optocoupler 5 on the close bottle cap end cover of this section of pipeline, enters pinch valve PV1 normal-closed end this section of pipeline near barrier film retaining valve 7 side pressure.Barrier film retaining valve 7 other end connecting tee joint 8, three-way connection 8 one end connects flow chamber outlet 9, intermediate duct is arranged two three-way electromagnetic valve V2, three-way connection 8 other end connecting tee joint 10.Three-way connection 10 one end is communicated with DIFF channel sample entrance 6 through pinch valve PV1 Chang Kaiduan, and three-way connection 10 other end is connected with DIFF reaction tank 11.Sampling needle 12 is fixed on sampling needle motion 13, sampling needle motion 13 can make sampling needle 12 do vertical and tangential movement, sampling needle 12 is connected with sampling syringe 14 by pipeline, and sampling syringe 14 is driven by motor 16, and is provided with dilution entrance 15 on sampling syringe 14.Connection=gas pressure sensor 3 in pressure chamber 2, in the force value of building in the pressure time in real-time monitoring system of regulation, after intrasystem force value reaches the target of setting, system will stop building pressure immediately, when building after in the pressure time period, force value is less than target setting value, system can perform immediately to build again and press work, if force value is less than certain value of setting all the time, it is unsuccessful that pressure is built in explanation, and the system failure is alarm at once.On the pipeline of bottle cap end B, a level sensing optocoupler 5 is socketed at powerful cleaning solution bottle 4 fluid pipeline, when having liquid and no liquid in pipe, the voltage signal of optocoupler receiving end is different, utilize this principle to monitor in powerful cleaning solution bottle whether also have liquid, it's not true will point out user to change.Powerful cleaning solution export pipeline is connected in series a barrier film retaining valve 7 between pinch valve PV1 and three-way connection 8.When push away sheath stream at leukocyte differential count time, pinch valve PV1 can power on, so the normal-closed end that powerful cleaning solution export pipeline is pressed into pinch valve PV1 will be opened, such three-way connection 8 has been communicated with to powerful cleaning solution bottle 4, the waste liquids having flow chamber outlet 9 to release pour in down a chimney the risk into powerful cleaning solution bottle 4, are connected in series a barrier film retaining valve 7 and just can solve this problem.To be pressed in DIFF reaction tank 11 whole process in bottle 4 at powerful cleaning solution, powerful cleaning solution is not inner by solenoid valve, there is not corrosion solenoid valve problem, and cleaning solution bottle two ends are all airtight under not using state, also there is not the problem of volatilizing and bringing.

The powerful cleaning solution automatic filling device of blood cell analyzer, its charging method comprises the steps:

The emptying pipeline of the mat woven of fine bamboo strips one step and pond liquid, utilize the original emptier of blood analyser by emptying from each waste liquid outlet to DIFF reaction tank 11, WBC counting chamber 17, RBC counting chamber 18.Emptying common pall utilizes the original device of blood analyser from the suction of DIFF channel sample entrance 6 until the pipe be connected with DIFF reaction tank 11 and three-way connection 10 is found time, and do not diluted when object is and allows powerful cleaning solution flow through this section of common pall by liquid in pipe.

The mat woven of fine bamboo strips two step pressure injection and the powerful cleaning solution of distribution, open two three-way electromagnetic valve V1, open positive pressure pump 1 simultaneously and build malleation in pressure chamber 2 and powerful cleaning solution bottle 4 at the appointed time, gas pressure sensor 3 monitoring pressure in real time value, stop building pressure after reaching set target pressure value.The size of target pressure value arrives the flow resistance of this segment structure of DIFF reaction tank 11 according to powerful cleaning solution bottle 4 and needs the liquid measure of filling and determine.To the powerful cleaning solution of DIFF reaction tank 11 pressure injection, open pinch valve PV1 after building pressure, powerful cleaning solution pipeline is communicated with DIFF reaction tank 11, under the driving of pressure, powerful cleaning solution flows into DIFF reaction tank 11 from bottle cap joint B.Pinch valve PV1 powers on opening time according to positive pressure pressure size and the liquid measure and determining of need annotating.Powerful cleaning solution distributes, after powerful cleaning solution pressure injection to DIFF reaction tank 11, sampling needle level 12 to move to above DIFF reaction tank 11 and then vertically again mobilely sampling needle is stretched in DIFF reaction tank 11 draw quantitative powerful cleaning solution by motor 16 injector-actuated 14 by sampling needle motion 13, the level that then rises again, moves vertically in WBC counting chamber 17/RBC counting chamber 18 and is injected in pond by powerful cleaning solution.

The mat woven of fine bamboo strips three step is soaked, after DIFF reaction tank, WBC counting chamber, RBC counting chamber all add the powerful cleaning solution of aequum, with blood analyser original parts, the powerful cleaning solution in pond is diluted, then the cleaning solution after dilution is transported to each position of analyser and soaks.

When the total consumption of powerful cleaning solution needed for three ponds is greater than pressure injection to liquid measure in DIFF reaction tank, second step can be repeated.
