What are the common plugging problems in the use of electrolyte analyzers?

Electrolyte analyzer is indispensable in clinical examination. In clinical practice, it mainly tests the balance of osmotic pressure in human blood and bodily fluids. In patients undergoing surgery, burns, diarrhea, and acute myocardial infarction requiring a large amount of balanced fluid replacement The testing and testing are very important. The instrument has high density and accuracy, and the results measured on any sample are accurate, reliable, fast, and easy to operate. In the following, Dongmai Science and Technology will introduce the common plugging problems in the use of the electrolyte analyzer.

1, pipe plugging

Observed through the clearly visible measuring chamber, the sample or calibrator fluid is not moving smoothly, and the active liquid is constantly shaking when the pump tube rotates, indicating that the cavity is not smooth. This is because the flow path is relatively thin, and flocculated fibers, leukocytes, and lipemia blood samples or proteins are accumulated for a long period of time during aspirating. The silicone tube can be unplugged, cleaned with fine nylon filaments, and then washed with a 5 ml syringe to remove the protein and repeatedly rinsed with distilled water. When the liquid is dripped at the discharge port when the sample is injected or flushed automatically, the pipe is shown to be unobstructed.

2. Electrode plugging

In addition to the reference electrode, other electrodes can be cleaned with fine nylon filaments. Reference electrode because the lumen is V-type, can not use fine nylon wire, 5ml syringe can be used to extract the calibration 1 against the sample injection direction, generally can be resolved. Note that the needle must not touch the electrode membrane. In addition, Cl electrode membranes are prone to dirt absorption and should be regularly cleaned.

3, injection needle plug

Due to the eagerness of the operator to operate the machine, the serum is forcibly separated when the blood is not completely solidified, and the sample again agglutinates in the sample cup to block the injection needle. Especially in the winter and when the room temperature is below 10°C, it often occurs. Therefore, the blood should be allowed to solidify, and serum should be separated for testing. Once the needle is clogged, the blockage can be expelled with a thin nylon or acupuncture needle (stocked).

4, waste outlet plug

In the season when the room temperature is low, the salt liquid crystals are often blocked by the waste liquid outlet, and they are not washed through repeated flushing. All the tubes can be removed and soaked in warm water of 45°C for about 15 minutes. Put the drift calibration solution bottle into the water bath and confirm that it has not frozen before loading the instrument. It is recommended to turn on the indoor air conditioner in time to ensure that the room temperature is maintained at 15 to 25°C.
