Maintenance must have been a delight. I can only guess they crammed so much in to get accuracy in a very small central processing area to deal with the tiny sections of blood. It's quite spectacular. I wonder how many tests it performed in its time. And how many times it dispensed bad news.
Really educational tear down! I've loved seeing the insides of such a complex expensive piece of kit. Thanks for doing this teardown! I do worry about part 3 though - "Mike contracts a rare blood disease from the blood machine!"
Absolutely fascinating Mike! Most of us wouldn't event know that equipment like this even exists, so thankyou for sharing this awesome tear-down. It's also suprising how poorly maintained such an expensive piece of equipment was, it looks like it has had many leaks over the years
That has got to be the most impressive bit's of equipment I've seen. Those ceramic blocks reminded me of the valve in a monoblock tap, same sort of ceramic discs sliding across one another. Loved the crazy machine at the end.
I was taught a little pneumatics while getting my electrician's licence, you and I and everyone else who gets their hands on that kind of hardware always make the same first project >_
I know a guy that used to work for a major darts manufacturer. He made some amazing prototypes. He made a dartboard tester with pneumatics rather than steppers/hydraulics, as it will give if it has a bang up on the wire. The machine has mashed up many dart boards. Many Many Many dart boards and still lives. All off a old school dip pic to.
Cool application for the 71 valves: line them all up and have them squirt water downwards. Hook them up to an mcu, time it all correctly and make them produce text/images with falling jets of water. :D
In Busan, South Korea there is a Lotte department store with a fountain in the middle of a 4 story indoor courtyard. On the bottom are normal fountain things that spray up, and on the top there is a ring of a good 100 or more valves that spray down, doing exactly what you suggest; writing, patterns, images, etc. The effect looks cool but sadly they start dissolving in the air a bit more quickly than would be nice, so it smears out by about halfway down. It's still impressive though!
If you could make it work behind a glass panel in some kind of vacuum chamber, or some other kind of controlled environment to keep the droplets contained better, it could look pretty awesome
Daniel G They should do what they do in 'Vegas and remove all the air bubbles to make the water clearer, maybe that would help "stick" the water together?
sashablfc yeah some kind of good nozzle design would be important. I think it would be expecting a lot to expect the water to stay together all the way down four stories in the open in the middle of a building!
Wow, what a fascinating tear down!! I used to work at a hospital (non-medical work) and saw what may have been older versions of the same machinery in action but from a distance; so they really are some of the more interesting machines to see torn down. Ancient high speed xerox machines are also quite good... ultra rare tho I really like the pneumatic build at the end there... maybe make a piston lift - ratchet to lift a big weight and another piston to release it to hammer something...
I work for a low volume high price medical manufacturer and you would probably find that all the looms are made by a loom contractor rather than having their own employees make up looms in the factory. Also the green LED to measure heamoglobin makes sense as green light wavelengths are highly absorbed by Heamoglobin so the more Heamoglobin in the blood the less green light that would get through to the photodetector.
Each time you said "swing out section", you kept reminding me of the 80s band "Swing out Sister"... which led me to their music videos ^_^ Brilliant video Mr Mike, thank you so much & God bless you :)
Amazing teardown! You could make a display with all the pumps and valves with some piping arranged in columns (maybe zig-zagging up and down a few times to get several columns worth from each one. Use valves/pumps to suck up air /dyed liquid in the correct pattern then pump it along till the 'image' appears.. Would look really cool when changing image with everything being sucked along.
Thanks for the tear down Mike, I enjoy your videos are find them fascinating. I really appreciate the time you take to go into detail about the individual parts, it's really interesting to see inside such a complicated machine that I would never be able to myself. Just one small thing for future videos, it would be really good if you could get a big powerful light source to help illuminate the equipment, in some wide shots it's a little bit dark and the low contrast makes it hard to see things.
At 23:25 it looks like you have a crystal gicleur. A gicleur is a flow restriction device, this one is probably made of crystal so that it is extremely resistant to mineral deposits that could otherwise block the flow completely
Hey Mike, If your camera has the option to record in 50 or 60 fps, please upload in those frame rates. There's too much motion blur when panning at 24fps.
Cool teardown. I bet the laser was stuffed, and needed regassing, never mind This bit of kit was probably running 24/7. It looks like it leaked reagents all the time as there is corrosion every where. Pity the poor service engineer who had to find the leak in this thing. Perhaps that why it went out of service? Leaky reagent crap everywhere. Small foot print is a selling point for a lot of lab instruments, as lab space is expensive to build and often limited in size. A Hospital pathological lab would probably have several of these systems, in case of breakdown ect. Just think this analyser is doing what a team of skilled technician would have done ten years ago. Hospitals have tons of cash for this type of thing. I would guess they have a well funded replacement program for this type of essential kit. Stepper motor and ball screws bonanza time on Mikes ebay!
These precisely surfaced ceramics disk you show at 30:00 looks somewhat like the disks you can find in a ceramic disk faucet cardridge. (taking one apart is a thing to do at least one time, you use it everyday and you don't know how it's made inside ?)
I imagine the machine has gone through a thorough cleaning and decontamination process when it was decommissioned from service. HIV infection is 0.3% chance of seroconverting with a hollow needle stick, and practically 0 from intact skin. The time the machine has sat around as well probably means that any remaining infective agents that remained after cleaning have become inert.
How on earth did anyone service these things? There couldn't have been more than a dozen people who knew the entire system well enough to really dig into a misbehaving and know what to replace and how
That collection of parts looks like something Tim Hunkin and Rex Garrod would have used to make a walking robot or whatever. It definitely has the potential to make a fund raiser gimmick for the local good cause.
Just found your channel and loving every video - but the end of this had me laughing hard!! thanks Mike! Did you make anything else with the pneumatics?
If the valves make any noise you could make a valve band and have them play some tunes. The pneumatics are just asking to be made into a robot of some kind. Make a tea machine or something.
I laughed out loud when I saw the pneumatic feedback loop you made!! This was electro/opto/vacuum/pron at its best. Great video. My suggestion for the actuators and valves is to simply send it straight to ebay.
I'm a bit concerned about the lack of gloves considering that this machine has seen the blood of a substantial amount of people. It's probably been flushed out, but the dried up pool of blood at 6:50 would have made me a bit uncomfortable. Then again, I'm not an engineer, so dismantling this kind of equipment with gloves might just be impractical.
I'd make a robotic arm out of all those pneumatic actuators. As for the valves at first I though an automatic watering device for seedlings but no there could still be contamination.
One of your best teardowns, Mike, Great cinematography (especially macro-photography). Good editing and "plotting": there is lot of time involved in the actual manual teardown and vidographing, and then figuring out which footage to keep or cut out. All hard, laborious work ... and it's APPRECIATED! About that complex device... Much of the high cost of healthcare -- at least in the US -- goes to pocket the CEOs of medical-technology corps and big pharma. The engineering complexity can be intimidating -- read: "only high-end companies can put it off." Maybe some of that complexity is unnecessary. How much can be done on micro-array or other biochip? And how much of the blood analysis can NOW be done on a smartphone-based device? I Googled "smartphone blood analyzer" and found some interesting stuff.
Nah, nothing was dumped into biological waste, it was just cycled with solutions that completely inhibit biological growth and kill already existing life(blood, diseases, etc). The entire thing is biologically safe, but that test head and blood residue made me jump a bit.
***** To decontaminate you have a few options, Heat like an autoclave and antiseptic solution like 70% alcohol, or formaldehyde (carcinogen), ethylene oxide gas (your would wish you drank the formaldehyde) or smiler or perhaps gamma irradiation via C60 source (fried electronics). Problem is that's a delicate bit of kit so if anything I expect the most would be to run a fluid of some sort thru it. As seen in the video there was plenty of gunk around the sampling processing units and perhaps in the lines and cuts on Dave's hands. :-(
Systemrat2008 His name is Michael, by the way. No, there are %very expensive% liquids that are specifically designed for these machines to kill everything and bring EXTERMINATION to diseases and bacteria. You just fill the sample cassette with a specific pattern of things(EXTERMINATUS liquid, then probably residue remover, then distilled water), and they get "sampled" the same way an array of blood samples would.
***** Great. I still have memory's of a low water use dialysis machines which was use by both military (desert storm) and civilians and it had lots of silicon hose and when you removed the clamps there was inevitably some dried blood slightly under the clamp area. For that reason hospitals had hot machines used on aids and hep B & C patients. I am super paranoid and used lots of protection. Perhaps the risk was very minor but not zero.
***** My guess would be the machine does that internally with hopper feed bulk cleaning chemicals (since it is used between every sample) -- the same reason as why the sampling head moves, not the tray -- because then the sampling head can retract and 'sample' some delicious kill-fluid :)
Christ on a bike Mike, THIS STUFF IS EVEN BETTER THAN PORN !! Thankyou so much for sharing it with us. It really is an incredible and beautiful piece of engineering - there are obviously some "bloody" clever people at Horiba (sorry). I've worked on some very high capital systems (ion implant) and I'm surprised it didn't cost more than the 250k you mention. I don't think I'd like to do a major service on it though... Great stuff Sir!! Thanks again. Really. ...
Curious to know why you buy stuff like this? Is it out of pure interest or because you have plans to use bits of the machine then get a bit of money back from the scrap? Or all the above? Whatever the answer we all like your tear downs.
Gillian Seed Dear Mr. Arrogance, Steve pretty much had answered his own question. Yes, It's all of the above - curiosity, plans to use parts, sell some components online, make an interesting YT video :)
where does all the cleaning/flushing liquid end up? is this machine supposed to be connected to the building drain? also it would be nice to know how much time it takes to assemble one of these puppies.
I'm pretty sure machines like this have a cleaning program/cycle which enables the operator to run cleaning agent through all of the tubes. I'm more concerned about the "drip trays" inside the machine. It's like an ink jet-printer with a biohazard.
Maintenance must have been a delight. I can only guess they crammed so much in to get accuracy in a very small central processing area to deal with the tiny sections of blood. It's quite spectacular. I wonder how many tests it performed in its time. And how many times it dispensed bad news.
I wonder what it would say if you tested gravy instead of blood…
Really educational tear down! I've loved seeing the insides of such a complex expensive piece of kit. Thanks for doing this teardown! I do worry about part 3 though - "Mike contracts a rare blood disease from the blood machine!"
Mike, you have built a priceless Rube Goldberg machine from a mere quarter of a million pounds worth of parts. I love it.
It was a useless machine, not a Rube Goldberg machine
Hayden Kibble
Maybe one of the most expensive useless machines ever since a very expensive piece of medical equipment supplied the parts.
Absolutely fascinating Mike! Most of us wouldn't event know that equipment like this even exists, so thankyou for sharing this awesome tear-down. It's also suprising how poorly maintained such an expensive piece of equipment was, it looks like it has had many leaks over the years

That would be a neat idea, a linear liquid display. :-)
If you could make it work behind a glass panel in some kind of vacuum chamber, or some other kind of controlled environment to keep the droplets contained better, it could look pretty awesome

It was great to meet you at the southern electronics show today. hope you found some interesting things
It's fascinating to see how these medical machines work. Thank you for sharing.
On your xray and medical gear teardown theme - next up should be a computed radiography digitiser. Crazy moving parts and photomultiplier joy.
Wow, what a fascinating tear down!! I used to work at a hospital (non-medical work) and saw what may have been older versions of the same machinery in action but from a distance; so they really are some of the more interesting machines to see torn down. Ancient high speed xerox machines are also quite good... ultra rare tho
I really like the pneumatic build at the end there... maybe make a piston lift - ratchet to lift a big weight and another piston to release it to hammer something...
YAYYYY !!!!!!! Best thing for a monday is a teardown from Mike ! Thanks !
that thing is immensely complex, to be honest 250k seems like good value for the amount of design that would go into such a device
I work for a low volume high price medical manufacturer and you would probably find that all the looms are made by a loom contractor rather than having their own employees make up looms in the factory. Also the green LED to measure heamoglobin makes sense as green light wavelengths are highly absorbed by Heamoglobin so the more Heamoglobin in the blood the less green light that would get through to the photodetector.

Disk is a laser cut ruby in suspect. I worked on a burn wound care tool with a similar, if thicker, disk.
Amazing teardown! You could make a display with all the pumps and valves with some piping arranged in columns (maybe zig-zagging up and down a few times to get several columns worth from each one. Use valves/pumps to suck up air /dyed liquid in the correct pattern then pump it along till the 'image' appears.. Would look really cool when changing image with everything being sucked along.

I'd hazard a guess that the electrical-conductivity blood cell counter aperture is made of synthetic ruby, judging by the rigidity and color.
One of the most interesting teardowns ever, thank you Mike.

I wonder how it scrubs itself between samples. Nice video, Mike. Thanks
Build a MIDI-controlled pipe organ/tin whistle array with all the valves!
Cool teardown. I bet the laser was stuffed, and needed regassing, never mind

Stepper motor and ball screws bonanza time on Mikes ebay!

I like the nice idea for a useless box at the end... please do something more with that.
Just found your channel and loving every video - but the end of this had me laughing hard!! thanks Mike!
Did you make anything else with the pneumatics?
I bet you could brew a fine wine with the runoff from a machine like that.
Excellent stuff. I think you could make a musical fountain with some of it.
If the valves make any noise you could make a valve band and have them play some tunes. The pneumatics are just asking to be made into a robot of some kind. Make a tea machine or something.
I laughed out loud when I saw the pneumatic feedback loop you made!! This was electro/opto/vacuum/pron at its best. Great video. My suggestion for the actuators and valves is to simply send it straight to ebay.
I'm not sure if I'm really impressed or really horrified at the build, etc. Great tear-down. Thanks Mike

All those valves and pneumatics would make an awesome Cocktail bar robot. Mines a bloody Mary
"... so produces a nice smooth sort of amount of suck"
Nice one :)

(sign above sink)
Wow. Great video. Great machine. Thank you Mike.
Best ending. Cheers, Mark
Love the pneumatic switch tester.
29:48 use them for a waterfall display... You could probably build it just from the parts of this machine
Love it, I'd like to get my hands on more kit like this to peek under the hood with.
Some parts of the machine would have gone into the clinical wast to be burned to prevent spreading infections and blood based diseases.
Nah, nothing was dumped into biological waste, it was just cycled with solutions that completely inhibit biological growth and kill already existing life(blood, diseases, etc). The entire thing is biologically safe, but that test head and blood residue made me jump a bit.

Wow, I one wonder how much just the parts and labour cost just to put that together?
What you can do with 72 valves? ofcourse a bubble display!
Christ on a bike Mike, THIS STUFF IS EVEN BETTER THAN PORN !! Thankyou so much for sharing it with us.

if you have to ask that question you wouldn't understand the answer
Gillian Seed Dear Mr. Arrogance, Steve pretty much had answered his own question. Yes, It's all of the above - curiosity, plans to use parts, sell some components online, make an interesting YT video :)
I like the pneumatic oscillator! :D
Is there going to be a part 3?
where does all the cleaning/flushing liquid end up?
is this machine supposed to be connected to the building drain?
also it would be nice to know how much time it takes to assemble one of these puppies.
Re size:
Maybe if you make it bigger, you'll need longer hoses and you need more blood to do the tests?
That was worth the watch just for that last bit :)
Dam i wish i had this thing
While watching the video: Isn't that Eurocard format for that cardcage?
I have a feeling that handling that stuff without rubber gloves could be potentially harmful.
how did they clean all that tubing to stop contamination of the different test vials of blood etc affecting the subsequent test?
Cool video. Thanks for sharing.
Are you selling the toroidal transformer and the stepper motors.
Shame about the argon laser - that would have been a nice score. :( Amazing teardown though - wow they did cram a lot in there :P
Shame that the wire tree is not done with good'ol cable lacing.
Loved the end bit! Awesome :D
Thanks for the ending smile
Hey, would you be interested in selling the keyboard?
How many feet of wire and tubing do you think there is all together?
Nice teardown : )
70+ liquid valves? time to make a miniature bellagio water show.
could you use the pneumatics to make some music, similar to using floppy drives?
35:10 - Having an argument with your girlfriend
Seems needlessly complicated. Must be possible to just get hte blood directly to whatever sensor is required instead of all the routing.
imagine you had to service these and clean every tube damn
I'm pretty sure machines like this have a cleaning program/cycle which enables the operator to run cleaning agent through all of the tubes. I'm more concerned about the "drip trays" inside the machine. It's like an ink jet-printer with a biohazard.
epic finale!
Oi, Ikea switch testing?
I love the useless machine at the end. Made me lough out loud !!
I like the end.
Love the way your brain works.
Hahaha...
Very cool ending... Thanks for sharing :)
mike how will you make your money back on it i bet it was not cheap
Mike, did you payed any money for this machine to just disassemble it ? or are you going to sell parts of it separately? just courious.
haha awesome oscillator at the end
Love the end. :)
Loved the end of the video by the way!
take a bow sir!
Mike tears down a medical instrument that cost in excess of £200,000 to give us the useless machine++
Sooo many valves? Oh please buy some pipes/flutes. Make a controller for this valves and a smal Programm :D Let it play cool music :)
@34min+ So epic!
Didn’t even trying powering it up…
I loathe those Watchdog / nvram / real time chips with the batteries in them.
Greate video, I think you just invented the first pneumatic useless machine!
Don't forget to suck your fingers when you done!
Dead good.
Bizare piece of kit :-) *lol@last minute*
love the useless machine in the end ....
lmfao pneumatic useless box. great video
Time to tear down some life support equipment.
