If it's "normally used for personal, family, or household purposes" or "designed or sold for incorporation into a dwelling", then anti-tivoization applies regardless of whether it's medical in nature. Conversely, if it's not either of those, then it's not a "consumer product", also regardless of whether it's medical. There are problems with that section, but "GPLv3 makes an exception for medical devices" is not one of them.
