I can't imagine that they will drive/fly from the headquarters to refill the disinfection fluid or wrapped material
there are plenty of local companies that can do that. companies that serve coffee machines could do it. that's not really an issue as long as the machine is well built for easy swap of materials.
I don't think it's really the same thing, there are way more electrical cards into health monitors I guess because there are more informations to process. It's also true that a good technician just needs the electrical scheme
Expanding globally sounds nice, but they should avoid to get lost in trying to make everything right on too many places at the same time. Better focus on one region at first and expand further as soon as everything is working there.
