I've been contracted to repair a cardiopulmonary bypass machine and
need a service manual.

Just wing it.
Don't forget to test it out after the repairs!

How complicated can a thing with pumps, tubes, and filters be? :)

Real engineers don't need the manual! Just test it on yourself
when you are done and let us know if you were successful. :)

I've got a mate who's a plumber and part time car mechanic. He should be
able to help you out on the job. Let me know if I should have him contact
you ...

Whatever you've contracted, the chemist should have a suitable
antidote for it. Hopefully, it won't be fatal.

I had a triple bypass done in 2002 and survived. (A triple bypass is
where they charge 3 times the normal price). I would be seriously
worried if the surgeons were reading a manual while operating the
machine. Never get caught reading a manual as the customer may
suspect you don't know what you're doing.

Anyway, fixing the machine is easy. Testing it, when done, is the
difficult part. I'm sure the surgeon will be happy to verify
operation using your heart. Don't worry... you won't feel a thing.

Yeah, what's the worst that can happen?

It was an easy fix. Just a blown fuse. But it was an odd physical
size I didn't have with me so I just wrapped foil around it and put it
back in the holder.

Didn't have a patient to test it on but the little thingys spun around
so I'll assume it will work.

Give the thingys a good spray with WD40 just to be on the safe side ...

Well, at least the foil won't blow in the middle of surgery. That
would be embarrassing. :)

Yep. Sounds like a 'good to go' thoroughly professional job you've done
there. Well done ! We're all jolly proud of you, mate ...

Wrong. Most patient attached AC powered medical electronics are
required to have either thermal or magnetic cirucit breakers. Some
also require ground fault interruptors. No fuses allowed.

Incidentally, in my bad old days, I used to carry a few pieces of
potentiometer shaft, cut to the length of the common 3AG fuse. A
solid bar of brass or aluminum is a far more elegant kludge than foil
wrapped around the fuse. I called it my universal fuse replacement.

But it was an odd physical
size I didn't have with me so I just wrapped foil around it and put it
back in the holder.
Be sure to clean your lunch off the foil before inserting it in the
fuse holder. Hospital contamination is a bad thing.

The "little thingies" are the gears of the parking meter or billing
machinery. There's a counter inside the converts rotations per minute
into dollars per liter. The recorded value is what's used to produce
the patient billing. Billing by blood volume is considered more
equitable than simply charging for runtime. The "thingy" section is
also one of the few parts of the machine that is utterly foolproof and
totally reliable, as it always seems to produce a gigantic bill.

Incidentally, it appears that you have been testing the machine on
yourself, as you seem to exhibit all the symptoms of postperfusion
syndrome, more commonly known as "pumphead".

This is where your intelligence level has been reduced to posting
drivel to usenet newsgroups. The bad news is that it appears to be
permanent. Please see a doctor or electrician for a much needed brain
boost.

I'll remember that next time.

UPDATE: The CPBM was used for the first time this week. But of all
people my ex wife! What are the chances of that??. Unfortunately the
CPBM stopped during surgery :)
