EBME Forums Forums Management Medical Equipment Management Maintenance Specification For Scopes And Assosiated Theatre Stack Systems

Does anybody have a maintenance specification for scopes and assosiated theatre stack systems that I could have a look at.

Do you mean an inspection/PM procedure for 'scopes and video stacks, Paul?

Yes Geoff that's exactly what I am after

It depends on the manufacturer - and at least one of them simply refer you to the manuals for all the items on the stack which give comprehensive check lists which are really only necessary after major repair / board replacement. Their engineers don't follow these instructions when carrying out the routine PPM, but they won't tell us what procedure or work instructions they do follow.

At least one manufacturer won't supply manuals unless you've done the training course either, so the whole thing becomes a bit problamatic !

How’s this? In days gone by, there were rules about how many broken fibres were permissible. They also had not to be clustered, or in the centre of the field of vision. Not sure what the consensus is these days (…but someone will surely tell us)!

Procedure FES-00-180 Time 0.3 hrs

Equipment : Flexible Endoscope
Manufacturer : Any Manufacturer

Interval : 180 days
Labour : 0.3 hours
Annually : 0.6 hours

==================================================

1) Carry out visual check and note any signs of deterioration.
2) Connect to light source and view to check for broken fibres.
3) Check controls for smooth operation.
4) Check that scope distal end reacts correctly to controls.

Procedure SVS-00-180 Time 2.0 hrs

Equipment : Surgical Video System
Manufacturer : Any Manufacturer

Interval : 180 days
Labour : 2.0 hours
Annually : 4.0 hours

==================================================

1) Check overall system for mechanical integrity.
2) Check castors for free rolling, movement and locking.
3) Clean where necessary. Remove surg tape and old labels etc.
4) Check system mains cable and plug.
5) Carry out electrical safety tests as far as main dist strip.
6) Check mains cable and plug of each component equipment.
7) Carry out electrical safety tests on each component eqpt.
8) Carry out a functional test on each component equipment.
9) Check operation of camera.
10) Check video quality at monitor and adjust as necessary.
11) Check interaction of camera with other parts of the system.
12) Check video and control connections and correct if wrong.
13) Check menu options and re-set if necessary.
14) Leave system cabling tidy and neatly stowed.

Tools: Normal Toolkit: Electrical Safety Tester

Note that each component equipment (video monitor, CO2 insufflator, light source, camera controller, printer, VCR etc.) should have its own individual inspection/PM procedure.

Yet nobody ever has!
