Wii Balance Board Gives $18,000 Medical Device a Run For Its Money

Gizmodo highlights a very cool repurposing effort for the Wii's Balance Board accessory. Rather than the specialized force platforms used to quantify patients' ability to balance after a trauma like stroke, doctors at the University of Melbourne thought that a Balance Board might serve as well. Says the article: "When doctors disassembled the board, they found the accelerometers and strain gauges to be of 'excellent' quality. 'I was shocked given the price: it was an extremely impressive strain gauge set-up.'" Games controllers you'd expect to be durable and at least fairly accurate; what's surprising is just how much comparable, purpose-built devices cost. In this case, the Balance Board (just under $100) was compared favorably with a test platform that costs just a shade less than $18,000.

"Not for ________ use"

What determines the price of a scale is not just its equipment or accuracy.. but also the insurance the manufacturer has to carry in case something goes wrong. That's why medical devices are more expensive... you're also paying for the liability of somebody being misdiagnosed by a technical malfunction. Highly unlikely, but the money that has to be paid when that happens and gets proven is huge.

What determinds the price is production, and demand. The wiimote is mass produced, which makes the price even less. And its in high demand.
Medical equipment? There is a certain number of hospitals involved ordering X amount of copies, and the demand is static. They will also pay for it. Basically its overpriced, but the question is how much its overpriced.

There is no justification for an $18,000 price difference for what amounts to the same fundamental technology. I don't need a formula, or theories as to why this is. The medical industry is full of a bunch of crooked greedy bastards. They use the same basic technology to accomplish the same result, probably with the very same components, all of which can obviously be had for very cheap. Costs are applied at the component level. If you can buy the same components for a Wii as in this other piece of equipment, their prices should be a bit closer. Our medical system has been gamed so badly for so many years, that a hospital doesn't even blink when they see $18,000 for a piece of equipment. They will happily pass the costs on to the patient, and the patients health insurance.

If this isn't a case of price fixing then I don't know what is.

What we really need is transparency is pricing for all medical costs. Force manufacturer's to provide their component costs for everything like eqiupment, drugs, and consumables, so that the consumer can see exactly what kind of markup their paying for.

You have obviously never worked in an industry with high quality control standards. The price of some product isn't the sum of its individual components. You have to pay people to design it, and people to test it, and then pay insurance on it. For small markets, this means that the price is very steep for even simple things. What would you price this device if the parts cost $100 per unit, but the R&D cost (2 doctors and 2 engineers for 1 year) was $1 million, the insurance cost was $500,000/yr, the customer support cost was $100,000/yr, and the market size was 100/yr?

> I guess we were paying $99 for the QC sticker they put on it before they sent it off through the supply system.

Actually, there's a very good real-world example of a cheap electronic component that nevertheless can be very expensive when its quality is absolutely certified: electrolytic capacitors. Today, in 2010, brand new devices are STILL being manufactured with electrolytic capacitors that have substandard electrolyte. This is a problem that was supposed to have gone away YEARS ago. Why is it still around? Because the bad electrolyte is a tiny, tiny bit cheaper to make... and the capacitors tend to work just fine for at least a few months. In other words, they fail prematurely... but not immediately.

If you're building something that absolutely, positively, must NEVER use an electrolytic capacitor with bad electrolyte, you have no real option besides buying only capacitors that are certified (and can be audited) all the way from you (the company building the device that uses them) to the chemicals used to make the electrolyte itself. It's not enough to buy "a good brand". To get that level of certification, every party along the way -- distributor, wholesaler, supplier -- has to be certified capable of keeping them secure and properly stored. Otherwise, an employee (or manager, or higher) at the supplier could substitute counterfeit capacitors, then sell the genuine ones elsewhere.

The point is, that degree of auditing and handling is insanely expensive, because it involves SO MANY different parties (all of whom want to be reimbursed for the extra trouble). It's made more expensive by the fact that there are (fortunately) very few things that really NEED that kind of quality control. Life support equipment and nuclear power plant control systems are obvious excamples where it's justified, costs be damned.

That said, this particular device isn't life support equipment, regardless of how hard someone might try to make it sound like the tiniest malfunction would lead to death or injury. I think it's safe to say that this particular device's price is all but guaranteed to come down a few thousand dollars if they want to keep selling it.

I can honestly tell you that you have no idea of what you are speaking. I work for a small medical device manufacture as a software architect/engineer. There are many reasons why a medical device is expensive. I'll enumerate the two that I have experience with. The first, and biggest is the FDA. We are a class 2 medical device, much like the piece of equipment mentioned in the article. So what does this mean? It means reams and reams of paperwork. Not nearly as much paperwork his required for a class 2 as a class 3 (pace maker and other implantable devices) device, but still reams of paper. We sent almost a WHOLE box of paper to the FDA when we submitted our paperwork. If I had to add up the cost to produce the paperwork, given the cost of lawyers, and staff time, my guess would be >$250k. Thats just the initial cost. We now have to get ready for an FDA compliance audit in the next few months. We have also have to overhaul how we develop the software. We have to be able to trace every line of code back to reams of paperwork, that adds an additional burden to the bottom line. Next are lawyers. We spent a TON of money on lawyers while doing our FDA 510K. Competent lawyers who are also knowledgable about the FDA 510K process are NOT cheap. ONE of the lawyers we used cost $600/hr. You also have to remember that the medical market is quiet limited. How is a small medical device company supposed to survive if they sell the device for a couple of hundred dollars into a very limited market? When you see our product, you might be tempted to think $5000? I'm not paying that much for a metal frame, a hardened PC w/ a touch screen and some software. Its not worth that much. And when you do, I want you to tell that to me personally, to my face. I also want you to tell me that my family doesn't deserve to eat.

We're talking about a diagnostic device. Not a life saving device. Not even for internal use. It is quantifying balance: we know the patient has balance, we just want to know how much of it. It is not even diagnosing whether a patient has a disease or not, or what disease a patient has.

If it is faulty, the doctors will know. Either it doesn't work, or the values do not make sense. A doctor with a little bit of experience will know from looking at the test about where the number should end up, and if out of expectations can take another device to test again. They're cheap, so you can have more than one on hand.

Sterility is not even an issue here (beyond basic cleanliness of course), it is not for use in an OR.

The main reason these things are/were so expensive I think is because of the very small product runs. Really small: hundreds, maybe a few thousand. There was no other use for these sensors, so development cost has to be shared over a few thousand pieces at most. Come the Wii with its gadges using basically the same tech, and both production cost and development cost per unit drop enormously. It matters a lot if you share costs between 1000 or 100,000 units.

Then probably the medical version is much stronger and sturdier, lasting longer, but the price difference is too big to make up for that.
