And I can tell you that nerve damage (especially around the fingertips) is important to glove manufacturers, especially concerning sporting gloves, where the risk of such damage is high with or without gloves.
And yet, they manage to make functional sporting gloves without a 100,000% mark-up over the cost of a DIY version. The people working with the affordable prosthetics are also interested in not causing harm. They (and sporting glove manufacturers) just have a proper sense of proportion about it and a better understanding of the actual risks.
As for watchbands, I actually do know a few people who've had allergic reactions to watchbands of various kinds, starting with myself.
OMG, terminal wrist irritation. How long do you have? Oh, just changed watchbands and all's well? That sounds much smarter than getting a $10,000 FDA approved watchband.
That's what insurance is for.
That's a good one! You do know there's a lot of people with existing amputations who have no insurance, right?
By that time, the damage may already be permanent. That's one of the things that research would study before handing it off to an unsuspecting patient.
So, constriction bands around the viscera and the neck can be unregulated but a velcro strap around the wrist is likely to cause a permanent injury? B_U_L_L_S_H_I_T.
And I must say, one of us certainly doesn't get risk analysis but it isn't me. Risk analysis does not mean freaking out at even the barest hint of the possibility that someone may get a rash.
As for the FDA and risk analysis, they haven't a clue. They're the organization that doesn't get that short term terminal patients have already lost what they have to lose. At the same time, they approve drugs that can cause homicidal rage (which has resulted in deaths) as a barely effective aid to quitting cigarettes. I fully agree that for controlled poisons (drugs) and implantable devices some sort of regulation is required but frankly the FDA isn't it. The whole agency needs to be chopped up for parts and replaced.
