Citation very fucking needed, because exceptions for specific fields of work directly contradict the underlying principles of the GPL, and indeed [0] contains no occurence of the word "medical".
> A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling.
The anti-tivoization text in the license applies to these User Products. Medical devices are not included in the definition.
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.
