Application of Blood coagulation analyzer

 Advanced medical equipment company production equipment in the hospital diagnosis and treatment is playing a more and more important role, along with blood clots conventional check into the automatic analysis time automatic blood analyzer for the application of the thrombus hemorrhagic diseases and before the treatment of thrombosis state prognosis analysis provides more actual indicators, the instrument of the detection speed, ensure the reliability and accuracy of the test results, the use of good blood clotting and instrument normal operation, has become a medical work related to ensure operation conditions.
 We depend on blood coagulation analyzer the use of the instrument should be pay attention to during mention some fellow views for the reference.

 Collection and save of sample
 1.1   The test specimen avoid blood fat happened, fasting blood for good, otherwise, it will influence the results, the process of blood had better not firm a tourniquet or try to firm pressure with small, short time, the smooth of blood, or a small clot and small sample redfiliform jams needle, affects the test results can't in passive congestion or was put on a drip take blood in the needle, don't beat blood parts, lest cause hemolytic ZuZhiYe mingling with the bubbles.
 1.2   Anticoagulation with 109 mmol  concentration, according to the proportion of anticoagulation and blood now.
 1.3   Test tube with the plastic pipe or the request of the glass tube carried the best specimens in one hour centrifugal separation plasma, four hours after the plug determination and don't open centrifugal, because can prevent CO2 to escape, change PH value can make the PT APTT results such as the extension with speed 2500 r/min centrifugal 10 ~ 15 min, or red blood cell plasma interference is determined.
    2.   Analysis
 First instrument to install in no vibration stability strong mesa, dustproof moistureproof with good ventilation in the environment.
 2.1  test reaction cup to clean, one-time glass and plastic products more suitable for this experiment, or join will have bubbles influence after reagent colorimetric determination
 2.2   Reagents containers and reagents don't put it on the apparatus, add reagent and instrument remove after put back, lest meet pour container and a reagent pollution instruments; Can't work while add reagent, to meet the required amount of determination, add reagent a add the, lest appear insufficient reagents and call the police phenomenon.
 2.3   The use of the reagents should strictly according to the requirements of the reagents into limit, placed longer time will affect the accuracy of the determination results.
 2.4   The determination to use clean liquid flush, remove the needle probe wall attachment protein, ensure the smooth wall two needles, no congestion, ensure that add kind not pollution reagent reagent needle.
