Automatic faults and processing coagulation analyzer faults and processing

Blood coagulation analyzer is a medical device company production of a high-grade test instruments. The machine set magnetic beads method, immune method, substrate than turbidity show color method detection method in one body. From the blood fat, jaundice, hemolysis interference, etc. And many blood coagulation index determination, such as PT, APTT, Fbg, TT, and clotting factor etc, with the man-machine dialogue function, use convenient, quick and accurate. But instruments sometimes also can appear a few small fault, now in the above points.
1 Normal fault and deal with the test results
1.1 All test results ERROR or > or < MIN MAX, and part of the abnormal results to be automatic heavy do normal (excluding specimen collection and reagents exception).
1.1.1 I needle or 3, needle aspiration kind not normal. Can be: (1) needle jam. Enter the NEEDLE with maintains menu wire the l or 3 NEEDLE, and execute NEEDLE PURGE blunt NEEDLE; (2) needle leakage. The way that NEEDLE tube rupture, it is the need to change the toolbox set aside a NEEDLE or lines, to maintain the execution menu NEEDLE REPLACEMENT for NEEDLE program and positioning change; (3) needle liquid surface detection fault. Check back needle liquid surface is loose and fault lines, reinstall the line and tighten, also can switch 2 and 3 lines of test, or into the main testing interface STATUS menu choice after SYSTEM, shielding 3 needle liquid surface function. Or turned 3 needle check if there is excess heat conduction silicon grease.
1.1.2 Electromagnetic valve EV1 fault. Emergency can use first tube directly meet people's congress barrel in the cleaning liquid, 3 two road electromagnetic valve components EV3 or EV5 fault and replacement parts.
1.1.3 Syringe is leaking. Replace syringe head, wash with water needle pool, the pool of a foreign body check whether, and 0.5% of sodium hypochlorite solution soaking wash needle pool.
1.2 A single project results abnormal heavy do little change after the results, the more complex for reagent solution is bad, or reagents save expired metamorphism. Replace the corresponding after reagents test.
1.3 Uncertain individual specimen for the individual project Err or > Max. At this time, should observe carefully needle of operation. We found through the observation, the needle sometimes not contact with liquid surface that is to take things, this is the needle liquid surface sensor connection wire caused by bad contacts. Reconnecting or replace then.
1.4 Equipment testing results failure analysis if and Fbg normal, and aPTT shorten or extend, should be the no. 2 and 3 needles; If Fbg normal and PT and aPTF are shorter, should be dredge 3 needles, and replace the DESORB. U; If PrI1 and am normal, and Fbg extend, it should check 1 needle, if both three-phase shorten or extend, it should be no. 3 needles or replace dredge syringe piston head, if all test newspaper Err or > Max, it sure is number one needle is blocked.
1.5 Don't sample Test instrument analysis of this fault first should check Test Satus of Test instruments of the reagents required for the project is all ready, and calibration and control is Validated, whether to stop the sample, the sample of the suction needle whether state locked, etc. After the check System Supplies of whether there is a warning. After the check for corresponding processing, instrument will work.
2 A suction cup measurement fault GRIPING CUVETTE ERROR and processing
2.1 Check no. 2 arm suction cup head whether installation rubber normal or have burst.
2.2 Suction head out, check whether there is a negative pressure suction nozzle metal, right and left two holes negative pressure is average. Failure can disconnect instrument a head right filter later reuse syringe without water washing by alcohol suction nozzle and pipeline.
2.3 Positioning 2 arm suck a head.
2.4 Vacuum pump diaphragm loss, general the situation with the small car take cup failure.
3 the small car take cup SHUTTLE MISSING and fault handling
3.1 Check out carries the cup after cup orbit with drawer whether there is a broken glass or rough, may withdraw from orbit after all cup manual rewind the cup into orbit.
3.2 Out right VAT and waste liquid instruments cleaning out the barrel black iron boxes, check the car position is correct or not.
3.3 To service menu, observe SHUTYLE measuring a load and execute a switch is normal or not. Check the outfit cup after five connection drawer thin wire is breaking off, with no alcohol clean water in a cup of drawer budge beginning and SHUTI 'LE slots.
4 No alarm 1/2/3 NEEDLE bending NEEDLE MUST BE BEND and processing
4.1 With studied WD 40 clean 1 arm X, Y, Z direction guide bar and axis.
Adjust 4.2 1, 2, 3, horizontal and vertical direction NEEDLE consistent, and the alarm bent pins positioning a number 16 incubation position, that executes maintenance menu replace NEEDLE program NEEDLE REPLACEMENT.
Automatic blood analyzer simple operation, easy maintenance, determination result is accurate, fast analysis, and to reduce the labor intensity of the inspection personnel, improve the working efficiency. But we should strictly abide by the procedures, pay great attention to the quality control inspection before, grasps the instrument principle of work, do the instrument maintenance routine apparatus, to stay at the best working state at any time, keep the higher accuracy and precision, so that we can guarantee the quality inspection, to provide more quickly, more clinical accurate services. In actual work, instrument breakdown, in time the right treatment can guarantee the smooth, improve quality, can prolong the service life of the instrument.
