What is Electrolyte analyzer common fault processing method?

Electrolyte analyzer is the hospital clinical examination the indispensable important medical devices, electrolyte analyzer in the clinical is mainly used to test maintain human blood. The blood osmotic pressure balance, in the surgery, burns, diarrhea, acute myocardial infarction and so on need a large number of equilibrium fluid infusion of the patients, the use of electrolyte analyzer to ion of testing and detection is very important. The precision and accuracy of the instrument is very high, for any sample measured results extremely accurate, reliable, fast speed, the operation is very simple. Sample can be whole blood, serum and plasma, urine, dialysis fluid, and hydration liquid.
Electrolyte analyzer to hospital so important, that if in use process appeared fault? For some common fault to how to deal with? The medical devices perlong small knitting to be a solution.
Electrolyte analyzer common fault processing methods:
A dull, suction sample, of the causes and treatment methods:
Suction sample impeded the major cause of basically has the following four, from the simple to the complex of thought to check;
1, check the line of each interface (including electrode between the electrode and even pipe, valve, between electrode and between handle) even tube if there is a gas leak, this phenomenon were not suction sample;
2, check the handle adhesion or too fatigue, if have, should be replaced new pump pipe. Phenomenon for the performance of the pump pipe issued abnormal sound;
3, each in the piping the layup if there is a protein precipitation, this kind of phenomenon for the performance of the fluid flow velocity process positioning instability, even in the new pump line also is same, solution to take down the joint water clean.
4, should also pay attention to is valve, carefully check.
Second, when there is detector failure is how to solve the:
The cause of the failure detector has the following kinds:
1, detector of plug and main board seat loose;
2, detector is broken;
3, valve core fixed screw and motor axis of rotation enough fastening;
4, valve core itself cannot turn too tight. Check the order of sequence for (3) - (1) - (4) - (2).
Three, electrode drift and the out of control causes and treatment methods:
1, electrode drift of the most common reason is ground missed, so should check ground; Check the drift of electrode silver bar is not insert signal socket or bad contact;
2, if electrode all drift, it shall check the reference electrode date is due;
3, positioning is bad, cause solution not all immersion electrode, should be reappraised positioning operation;
4, reference electrode above have bubbles, should pat flow cell, will bubble moved to Na electrode above;
5, voltage instability, had better pick UPS uninterruptible power supply or quality better regulated power supply;
6, avoid electromagnetic interference, power larger equipment should be as far as possible from the instrument, independent set up power;
7, inspection standard liquid and cleaning is finished;
8, check circulation pool reference filled with liquid is too little, and timely fill,
9, Na, pH electrode drift application in glass electrode cleaning fluid cleaning. Garnish with distilled water is rinsed repeatedly can;
10, reagent expired or polluted, check A and B standard liquid and cleaning fluid bottle, whether to have flocks.
Four, test blood sample abnormal value reason and solution:
When the test of blood samples, if abnormal value, according to the following steps to check:
1, whether there is a high power electric start near or leakage (such as: refrigerators), cause a voltage fluctuation;
2 at the time of the tests, suction clotting;
3, solution is not in place, can check whether the position is good, if the solution in place is not good, usable service program repositioning program for repositioning;
4, check put blood vessel is pollution, whether residual the disinfection of substance;
5, check correction factor is correct, whether to have abnormal phenomena, such as a anomaly, the correction factor cleared;
6, whether long time not calibration, the calibration can be measured again after again.
Five, the electrode slope reduce, processing method is as follows:
Electrode slope low, can cause test linear bad, sometimes will affect electrode repeatability, the main reasons are as follows:
1, temperature is too low,
2, life maturity;
4, air humidity;
3, electrode film board adsorption protein too much.
