Recently, the purchase of our medical device company by the production of biochemical analyzer always appear problem, on test results, although and medical equipment company after contacts have to solve the problem, but in case the similar problems, summarize the following a few simple maintenance and maintenance skills.
A. The daily maintenance
(1). Before starting :
1. To examine two cleaning trough 1 D1, 2 of the liquid will be enough for Hitergent D1 amount.
2. Check the small sample trays W1 a 2% Hitergent whether fluid enough quantity.
3. To examine two pack cleaning reaction cup of cleaning in the bucket washing liquid and 0.1 2% Hitergent mmol/L HCl is enough quantity.
4. Check printing paper.
(2). After startup:
1. The executive photometric inspection.
2. Check and additive reagents.
(3). The phone was off:
1. With no water alcohol from up to down carefully wipe the tip and stir bar, in polished stir bar don't damage when its surface hydrophobic material.
2. Empty waste liquid barrels.
3. If the sample slot have dirt, gauze to wipe.
2. Weekly maintenance and maintenance
1. In two cleaning trough 1 D1, 2 D1 a 2% change Hitergent liquid, and the implementation of the "Wash Cells".
2. Blank and print data determination cup, requirement as follows:
(1). 1, the value of the cup reaction not greater than 16000;
(2). 2, 160, the value of the cup in + 800 range.
3. Cleaning reaction cup:
If the execution "Wash Cells", a cup of blank do not meet above requirement, the reaction cup soaked in 2% Hitergent out in the fluid of more than 2 hours, use a swab to wipe, and pure water flushing, fully Wash clean install, and then execute a cup was blank.
3. Monthly maintenance and maintenance
1. Cleaning three screen:
(1). The shrinkage filter pressure machine;
(2). The service entrance screen;
(3). The reaction tank drain screen pack.
2. Two cleaning system:
(1). Cleaning suck the needle, needle and sample reagent stir bar washing the pool and pipe:
A. flush with wet with the brush pool tube 2% Hitergent liquid brush net;
B. first 10 ml 5% sodium hypochlorite liquid injection pipe flushing eduction, garnish with pure water flushing 3-4 times.
(2). A cup of cleaning system no. 1 needle: at boot status, the no. 1 needle, take it out of a small beaker filled with 5% sodium hypochlorite liquid, with the hand to control the needle with other needle as synchronous movement up and down.
3. A reaction tank:
(1). The reaction tank discharge water:
A. with injector spare water trough;
B. or executive "Inc. Water Exchange" (when the response of the Water tank when shutdown at once).
(2). With gauze with 2% Hitergent liquid cleaner reaction tank;
(3). Use a swab with 2% Hitergent liquid wipe two pervious to light window.
4. Every quarter maintenance
1. Change than color cup: in practical application replaced every six months, depending on the specific cup blank and decide, when a cup of blank is not accord with the general proceed as follows operation:
(1). In two cleaning trough 1 D1, 2 D1 a 2% change Hitergent liquid, and the implementation of the "Wash Cells".
(2). Take the reaction cup cleaning;
(3). The reaction tank cleaning;
(4). Put on a new light bulb;
(5). Put on a new has set up a file in Hitergent soak overnight in the fluid of 2% with pure water thoroughly clean the cup after reaction.
2. Replace sample syringe gasket;
3. Copy, replacement system disk and data plate.
Five. Every half year maintenance and maintenance
1. Replace light: (as long as have the following circumstances)
(1). Executive photometric inspection, if absorbency value beyond 16000, eliminating reaction cup and reaction tank pollution situation, should be to change;
(2). Light use time more than 750 hours, should be replaced.
2. Cleaning floppy disk drive;
3. Replace mechanical butter: first use gauze to wipe away the sample needle, needle, plus sample reagent stem butter, again with gauze daub the fresh butter.
