Yes, yes, Richard. But you could fix the things with bits form the souk! And wasn’t that a windscreen-wiper motor or something?

Landrover wiper motor - if I remember correctly
Hydraulic motor solenoid in the bottom of an Eshmann table is a Lucas lorry starter solenoid. They had not even bothered to take it out the box when we ordered an "official" spare part.

Hey Graham, that sounds like a business opportunity, Man! I know that many biomed departments still have boxes of old LSU bits lying around. Maybe we should buy them all up! We could keep these classics going for ever, or bung them on eBay . Anybody want to have a go?

Here we go! Better check out this one ! Looks like a few bits may still be available .

Meanwhile, here is a new one waiting for the bus!

Nice one, Robert! Any more like that? Anyone ... ?

In the appropriate thread, of course.

Anyone thought of trying injector suction? Some good units out there.

Good for a laugh when the staff insist they can hear them leaking (whilst operating)

Thanks for those excellent suggestions, I'm following them up.

Mr Ling has no need to use water and a stopwatch to test the flow rate of any suction machine! In Lincoln we use a gas flow meter set to measure air flow to check the suction flow. The old style Laerdal suction unit is expected to be able to produce 10 litres / min on half setting and 20 litres / min on full setting. The new style one is expected to produce > 25 litres / min at maximum setting.

Unfortunately, at the time, Mr Ling did. I think the volume of water aspirated in n-seconds was used to give us a clue to performance (actually this was recommended by the manufacturer). Measuring water volume and time is easy (without a flow meter) but it can be a bit messy. Otherwise it's a bit subjective trying to guess performance of anything that "sucks or blows". We use the newer LSU and have fancy flow meter(s) where I work nowadays. The older LSUs are just too unreliable in my experience; irrespective of how much suck they have on a good day and how accurately it can be measured.
