Can it be sterilized between cases (asking for a friend)?
Since it isn’t a med device listed with the FDA then it hasn’t been subjected to sterilization coming out of the box nor is it likely to be able to be sterilized by the hospital since most of them use only steam sterilization and this being commercial electronics is likely not sealed sufficiently and would likely require x-ray sterilization. (Ethelyne Oxide would likely oxidize the electronics and is unavailable at any hospitals I know of anyway).
Note: Apple isn’t claiming it as a med device and hospitals have a lot of leeway in what they use as they don’t fall under the FDA.
