Blood count by the fault reasons of the WBC count

Blood corpuscle counter will have some trouble in the process of detection, which is one of the WBC count is in failure, general instrument fault may have multiple causes, the WBC count perlong medical equipment small make up to simple analysis: ground wire or the surrounding environmental factors such as: power supply voltage change, under the electromagnetic field interference can cause blood counting instrument such as the pulse of change, make the results of the analysis deviation; The WBC count pool, instrument about congestion can also lead to the failure of pipeline system; Hemolysin and hemolysin line problem.

Failure after our first, inspect the instrument enclosure grounding, grounding through inspection is good. At the same time, the instrument is equipped with a regulated power supply with printer is grounded. After startup failure phenomenon still exists. Then consider the machine and radiology department on the same floor, space interference radio frequency electromagnetic field may also affect the count, lead to the occurrence of the fault. Place the instrument to the other place, away from strong magnetic field after boot failure still cannot be ruled out. Finally, the pipeline system of a careful check, especially for the pipeline of hemolysin key check and modification, boot after troubleshooting.

Specific methods: remove hemolysin of reagent package bottle, into the instrument is placed on the left side of the cleaning fluid next to the bottle. So that we can make the hemolysin and form shielding line, better to eliminate interference; At the same time, greatly reducing the hemolysin line, reduced the hemolysin pump load. To connect the instrument on the rear panel of hemolysis agent pipeline, the internal connection of hemolysis agent pipe connected to hemolysis reagent bottle. Open the instrument panel on the right side, modified with hemolysis agent pump connecting pipes and valves. Because of the severe pipeline by 2 hose coupling, is formed within the narrow, make the liquid flow is not clear. The original 2 hose coupling to 1 hose coupling.

Summarize the above faults are classified three blood count apparatus of a typical fault, also applies to other types of classification of three blood cell analyzer the WBC count failure handling. Hemolysin and hemolysin, hemolysin pump, check valve and pipeline filter is the main factor resulting in failure of the WBC count, failure to focus on analysis and judgment in maintenance, and troubleshooting.
