12-Lead Clinical ECG Design Open Sourced; Supports Tablets, Too
New submitter isza writes "MobilECG is probably the first open source clinical-grade electrocardiograph with simultaneous 12-lead recording and Android support. It has been designed to meet all the relevant medical standards (ISO 60601-1, etc.). Manufacturing cost @ 1000 pieces: ~$110. I had worked at a medical device company designing clinical electrocardiographs for three years. Fed up with the unreasonably high price, cumbersome design, and dishonest distribution practices of clinical ECG machines, I started working on a high-quality ECG that is different. After a couple of failed attempts to get funding for the expensive certification process and completely running out of funds, I decided to publish everything under a license that allows others to finalize and manufacture it or reuse parts of it in other projects." From the project page linked: "The software is licensed under WTFPL, the hardware under CERN OHL 1.2," and a few words of disclaimer: "Note: the design is functional but unfinished, it needs additional work before it can be certified. There are also some known bugs in it. Most of the software is unimplemented." Conventional crowdfunding may have fallen short, but Isza has proposed an interesting bargain for working on the project again himself: that will happen if he raises via donation half the amount of his original $22,000 investment.
Seriously, why? The study of medicine has only one goal. Improve the life expectancy of human beings. Surely any profession in which proactively benefits the human race should be patent and royalty-free to allow other human beings to improve and advance the technology. Why should we pay $1000's for clunky and out-dated machinery when computerisation has allowed us to minaturise, improve and cheapen, the manufacturing of medical devices.
I'm glad there's some people in this world who see sense rather than paychecks.
If you gave me a choice between a printer and a giraffe with explosive diarrhoea, i'll get my ladder and my raincoat
We can come up with a million dollars to make a sequel to one of the worst games of all time, Myst, and we can't come up with $22,000 to actually change the world?
Here's a medical device that meets none of the standards of today, and it has bugs that need to be worked out.
There's a difference between "meets none of the standards" and "compliant, but untested".
Please don't sell something short by making unwarranted accusations.
I have been a certified/licensed EMT for over 10 years.
"Medical devices are expensive to make."
For many commonly-used devices (ECG, pulse oximeter, etc.), the level of technology implemented is magnitudes less than that of a decent smartphone. Sure, these aren't mass market items--but I'm also hard pressed to understand why it doesn't make sense to have an alternative to a LifePak which easily costs $15K+. Case in point: the AED you can easily buy from Costco in the neighborhood of $1K--and has lots of sophisticated logic. Just because the thing has blinky lights and makes "bing" noises doesn't mean it should be exorbitantly priced.
"People need a manufacturer big enough to sue."
Circular reasoning on the best of days. Does a commercial implementer of this device need a legal team? Yes. Is the pragmatic implementation of a device at lower cost that's reliable and lawsuit-resistant possible? Absolutely.
> There's a difference between "meets none of the standards" and "compliant, but untested".
No there isn't. You comply with the standard when the pass the tests. You comply with nothing before that point.
The long and short of it is that you don't get sued for false positives, but you DO get sued for false negatives.
Any device that can't pass testing and demonstrate that the balance is in the favour of false positives simply will not be used.
Period.
In the other hand, a device that you can't buy or is not available probably will harm you more than not having it. Making devices/drugs/whatever that could be the difference between life and death for a lot of people, but have to have to add a "sue protection" price bump makes it not available for anyone,
Making it open source, and easy for anyone to build it also make people to decide which is the biggest risk, using it or not. Big companies could make the insured, high quality, throughly tested and expensive version, smallish/hobbyist could make the evaluate and take your risks cheap ones. They are not exclusive alternatives, and should not be neither.
Modern medicine works on the basis that dead people rarely sue. The same goes for other mission-critical systems like fly-by-wire avionics. To be fair (me? fair? well, it was bound to happen eventually), a lot of companies put in a lot of effort to do a good job. The problem is, if you're on life-support or flying at 20,000 feet, there is every probability that a software crash will be followed by a crash of another sort. There have been very close calls of this nature in the past.
But what would happen in the event of a fatal incident? In virtually all industries that use mission-critical systems, there are disclaimers and waivers that prohibit lawsuits.
Even in non-critical systems, EULAs invariably state the manufacturer/developer is not at fault, no matter what, even if they admit they are, and to use the system you have to agree to that. You aren't given a choice.
Open Source licenses often say the same, but Open Source allows you to validate the system to your satisfaction. You are prohibited from any code analysis and certain forms of runtime analysis with closed systems. Thus, although neither provide any form of warranty or fitness for use guarantees, you are capable of at least certifying open source as fit for use. No commercial product using computers will provide anything remotely close.
It's a small world and it smells funny; I'd buy another if it wasn't for the money; Take back what I paid (SoM)
But only a start. Researchers using - it was either 48 or 64 leads - were able to identify specific muscles that were showing abnormalities long before those abnormalities turned into organ failure. Isolating problems to that degree just by collecting more of the same data would seem a great way to help prevent problems serious enough to show up on a conventional system ever developing in the first place.
In other words, why not turn thus from being open source medicine into an open source debugger? Why let things get to the point where medicine, rather than our own creativity is needed?

Okay, this may be a stupid question, but I only count 10 leads in the pictures of the device, so where/what are the other two? Grounds?
lead != wire in this context, it refers to the electrical paths through the body between various parings of the 10 wires.
The curse of Open Source. Good luck getting that last 10% finished.
I want to delete my account but Slashdot doesn't allow it.
fwiw... It's 230 K, not 22 K$. but doesn't change your point. ECG is so nerdy... He should emphasize other uses, and try to market based on that. He could call it a "biorhythmic training device for understanding the crystals, and getting in touch with your aura. or talk up the "biofeedback" aspects of it, how it will help with meditation. That will sell to one crowd. Figure out how to use it as a kind of game controller, and the internet will fund in a (wait for it!) heartbeat.
Low cost, high profit: Perhaps commercial ECGs and other medical devices are built just like this power supply:

I lost a son, age 25, to sudden cardiac arrest. He left the gym, died a half hour later in his office. We thought he was the healthiest one in the family. Every gym should have an EKG machine as well as an AED. I hope you never learn what I know --- no loss exceeds losing a child. Search for Jos Claerbout
"...of clinical ECG machines" (summary). Does the submitter or anyone else care to elaborate?
wtf is wrong with you guys? it has no official medical use before certification and he can't afford it. it has no implied warranty. there's no fucking way to sue 'em if you use it for something, if you want to use it for something go through certification first.
and as far as copyrights go yeah, it DOES have meaning: do what the fuck you want. besides, FSF agrees. it's as free as you can get. what the fuck is wrong with people who think it has no meaning in copyright? because it sure fucking does! why the fuck it wouldn't? because it has "fuck" in there in the name? it gives you explicit permission to do whatever the fuck you want with it.
you don't like it? well fuck, create your own fork and license it under gpl! or bsd! or apache!
(and I can think of a bunch of things more necessary to have warranty disclaimers like any heating system control systems like on every friggin 3d printer which may burn your house down)

"Any device that can't pass testing and demonstrate that the balance is in the favour of false positives simply will not be used. Period."
Except if you're in a third world country where they don't have standards and where even something that is only right even only half of the time is infinitely better than nothing.
"> There's a difference between "meets none of the standards" and "compliant, but untested".
No there isn't. You comply with the standard when the pass the tests. You comply with nothing before that point."
Yes, there is actually. You can run the test yourself and meet all the standards yet not get certified because you are not an official testing body. E.g. I can get NASA to test that the bicycle helmet I made meets the Australian Standards, and you can bet your arse that it'll be an accurate result, yet it still won't be certified since they aren't certified to test it.
