The maintenance ,alarm and processing of blood analyzer

    Automatic Blood Coagulation Analyzer is purchased  from 2005 in our hospital.It has brought convenient to the work and provides the more accurate results to the clinical. But in use process all can't avoid for various reasons, have this or that kind of failure, but the failure rate just in different instruments. To guarantee the normal work of the instrument, to the instrument for regular maintenance is very important. Therefore, in order to put the instrument in the best state work, except the operating personnel to this instrument performance has a more comprehensive understanding of the staff also often to the instrument for some daily maintenance , so as to reduce the instrument in use process because of failure and affect the accuracy of the results, and reducing the instrument malfunction and produce the waste of resources. At the same time in during the work that the instrument has alarm to make timely corresponding processing. Now the methods of  the daily work, some simple maintenance, maintenance of automatic blood coagulation analyzer are concluded and peered learn together.

   1 Instrument Maintain   For keeping the ideal state of work, must be carefully safeguard. Maintenance is divided into daily, weekly, monthly, and every two weeks a year. The daily work is often do maintenance summarized as follows:


   1,1 Daily Maintenance    In order to get the best results, this machine has been in the state to boot. Reduce instrument "on" and "off" times. Before working every day to check  the amount of liquid whether enough, and reagent liquid surface height should ensure that no less than 210 cm high. Check waste liquid barrels of liquid surface height, confirmed that waste liquid to smoothly to waste in the barrel and, when necessary, to empty the waste liquid. To avoid causing waste liquid pipe of the jam by blood clot formation, every time to complete daily work to implement a waste liquid pipe cleaning process.


     1.2 Weekly Maintenance    Brush the instrument appearance, automatic vacuum device, sample than color dish interval part (not including than color dish holder) with  0.1 mol/L HCl and then use deionized water rinse. Clean needles to ensure that remove the needle protein and other internal and external sediments. When the specimens spatter to automatic vacuum device, or samples than color dish interval parts, to automatic vacuum sample device, color sensors and measuring cup than two of the room light path parts for cleaning. With 0.1 mol/L HCl dilute solution of clean cloth or after soaking wipe a swab than two color cup sensor vertical plane, then use deionized water cleaning and clean cloth or a swab dry.


     Instruments in the daily work of the common fault and its corresponding processing methods and the cause of the problem is very complex.Not only is the instrument itself, also involves the instrument and apparatus operator in the external environment. As long as the operator, the instrument itself and the environment in the three any problems, it can lead to medical test instruments of failure. Therefore, the operator, the instrument, the environment they form a medical test instruments of the three important aspects. Now the operating automatic blood coagulation analyzer to some common warning and when its corresponding processing method summarized as follows:


    2.1 The instrument shows "INCUBATION TEMP OUT OF RANGE"means the temperature of the color storehouse is high  (39 ~ 50 ℃) or low (20 ~ 36 ℃), correct temperature is 38.5 ℃. Treatment: if the instrument shows the temperature too high, then check the ventilators and around of exhaust equipment whether in the range of the instrument .If display temperature too low, then check the heater device and the temperature around, best is greater than 15 ℃, if correct mistakes after still exist, then contact please engineer.


    2.2 The instrument shows "CYCLE ABORTED NO FLUSH OPTIC ERROR) means liquid finished, and light path ERROR occurred. The cases above except's participation,there is another solution,staff take the washing liquid into than liquid, the device also will alarm this ERROR.Treatment:When change the liquid,take care the right liquid.


   2.3 The instrument shows "NOT IDENTIFIED SAMPLE IN POS" means samples and sample plate input the actual Numbers do not tally. Treatment: to check input samples and make the number of the actual equal to the input amount.

Five anticoagulation test by blood coagulation analyzer

   Research found that abciximab intravenous drugs for patients with acute myocardial infarction and the ones who has one-time coronary artery is no profit. Coronary artery to medicine can reduce the incidence of heart failure. In through the blood clots analyzer test results indicate that the 7% patients with coronary artery to medicine group of death, and intravenous treatment group was 7.6%, there was no significant difference. Coronary artery patients with heart failure treatment group of lower incidence vein treatment group. Abciximab coronary artery to drug safety and not a significant increase in the risk of bleeding.
   
    ISAR-REACT 4 research (randomized double-blind design) found that, compared with Bivalirudin, abciximab and ordinary heparin failed to significantly reduce/death and heart attacks, and serious bleeding rate significantly increased. The study included 1721 patients without st-segment elevation acute myocardial infarction (NSTEMI) patients, and the random points into abciximab and ordinary heparin group than cut LuDing/or group. The main events of the composite end point for 30 days for all, and death, and again hair large myocardial infarction, emergency target blood vessels reascularization or massive haemorrhage, secondary end points for death, any again hair myocardial infarction, or emergency target blood vessels reascularization (efficacy end point) and serious hemorrhage (safety end). The results showed that single of o company general heparin group, fell LuDing/than the main end event rates of 10.9% and 11.0% respectively, secondary efficacy end point event rates were 12.8% and 13.4% respectively. In safety, and LuDing group than coming, compared with common abciximab heparin group/serious bleeding significantly increased incidence (2.6% to 4.6%).
   
    ADOPT study (randomized double-blind design) found that review, sand class 30 days of treatment venous thromboembolism (VTE) prevention effect, no better than enoxaparin for 1 ~ 2 weeks, and significantly increased bleeding events. The study included 6528 patients with congestive heart failure, acute respiratory failure and infected patients, random to enoxaparin (40 mg, qd) subcutaneous injection 6 to 14 days, sand class with aripiprazole (2.5 mg, bid) oral 30 days treatment, compare the two treatment on hospital in patients with venous thromboembolism (VTE) prevention effect. The results showed that enoxaparin and review of the team, sand VTE rate were 3.1% and 2.7% respectively, both no significant differences. And enoxaparin compared to review the shift of the bleeding, sand significantly higher rates (0.19% to 0.47%).
   
    TRACER research (multicenter, randomized double-blind design) found that, compared with placebo, Vorapaxar (new selective protease activation receptor-1) failed to significantly improve the st-segment elevation in patients with acute coronary syndromes prognosis, and significant increases in serious bleeding and incidence of intracerebral hemorrhage. The study included 12944 patients without st-segment elevation in patients with acute coronary syndromes, random be Vorapaxar (new selective protease activation receptor-1) or a placebo. Vorapaxar starting load is 40 mg, then to 2.5 mg/d oral. The primary end point for cardiovascular death, myocardial infarction, stroke, because again hair ischemia and readmission to the hospital and emergency coronary artery blood luck reconstruction. Research results show that the 2 years of follow-up, Vorapaxar and placebo groups of the primary end point event rates were 18.5% and 19.9% respectively. In safety, compared with placebo, Vorapaxar group of GUSTO moderate to severe bleeding events (5.2% to 7.2%) and intracranial bleeding events (0.24% to 1.07%) increased significantly.
   
    ATLAS ACS 2-TIMI research (randomized double-blind design) found that, compared with placebo, and cut sand class (2.5 mg, bid) used for acute coronary syndrome patients in hospital, significantly reduce the death, heart attack and stroke incidence; At the same time the significant rise and coronary artery bypass irrelevant to the incidence and serious bleeding intracranial hemorrhage rate, related fatal bleeding incidence and placebo quite. The study included 15526 patients with acute coronary syndrome patients in hospital, randomly assigned to the sand fell 2.5 mg class (bid), 5 mg (bid) or a placebo. The primary end point for cardiovascular death, myocardial infarction, or stroke compound event. All participants will receive a small doses of aspirin and (or) [b] thiophene pyridine classes drug therapy. Results show that, compared with placebo, the sand fell significantly lower class the event rates in the primary end point (10.7% to 8.9%), and a significant rise and coronary artery bypass irrelevant to the incidence of serious bleeding (0.6% to 2.1%) and intracranial bleeding rate (0.2% to 0.6%), related fatal bleeding without obvious increase rate (0.2% to 0.3%).
