A blood cell analyzer can also be called a hemocytometer, which is generally used in hospitals. It is an instrument that is widely used clinically in hospitals, so what are the faults of the blood cell counter during use?
Common malfunctions:
1. The background is wrong when counting. Set the automatic detection blank value during cleaning. If the detection blank exceeds the specified value, an alarm will be issued, and you can know that a background error has occurred. First, check whether the diluent or hemolytic agent has bubbles and is contaminated, and if so, replace the reagent. In addition, it is necessary to check whether it is interfered by electromagnetic waves and to ensure that the grounding is good. In addition, if the pores of the detector in the detection room are contaminated, it will also cause the fault, and the maintenance cleaning program can be started for cleaning. If none of the above causes, you can check whether the rotary valve is contaminated and deal with it accordingly.
2. RBC/WBC/PLT counting error. You can first check whether it is caused by sample agglutination, and replace the sample if it is. If it is not the reason for the sample, you can check whether it is interfered by noise, electromagnetic waves, whether the grounding is faulty, etc. In addition, abnormal emptying of the insulation chamber below the RBC, WBC and HGB detection chambers can also cause this fault and should be eliminated. Check whether the detection chamber or the pores of the detector are contaminated, whether the pores of the detector are damaged, whether the pipeline between the cell counting quantitative diaphragm pump and the detector is blocked, etc. In addition, it is necessary to eliminate the circuit board failure, and check NO6363 and NO2135.
