Maintenance of Common blood coagulation analyzer

Automatic blood coagulation analyzer is a medical device company development production in use process also can appear problem, the following two cases of mainly introduces the typical fault and maintenance.

Fault one: mechanical means often can't catch or scratching the sand reaction cup, and in the process of mixed with reagents often off cup, respectively, alarm: catcher error catcher tube error.

Breakdown maintenance: first into the maintenance model: in work list under the menu 1) No. Entry the list please input son C and a 0, determine the junior people maintenance model, in the Main menu son service under the list, into the Mechaposting adjustment of the machine in each point of the pupils, adjust the end, do the specimen, fault fault phenomena and still No any law and the machine as long as mechanical means a alarm, will break all ongoing blood control, to stop the machine immediately, so it was a waste of reagent and reaction cup due to mechanical handholds on the series of actions is a multiple motor do together, so basically ruled out more motor working at the same time not stable may, the question should be out in a few.

Fault two : Reagent needle and samples in different locations appear needle pin phenomenon, alarm Reagent (sample) probe crash.

Breakdown maintenance: boot do specimens, found reagent needle and sample needle often will needle partial, and the needle is far away from goal slant, even if was flush sometimes also can not find position, alarm phenomenon without any law is due to the position of the two needle problems at the same time, the fault a considered the main experience in two needle common driving parts according to the fault in the process of a maintenance experience, to pull out two needle inserted the control line line, was not found to have cracking phenomena, do stop on a fault specimens still above that, go down two needle control row line Numbers as the master find 2137 circuit boards, found the Jll row line plug obvious loose the reason may be installed in the process, insert the plug into the slots doesn't put it, slot end of the bands didn't role, so that the stress on both ends of the plug rough,
