Typical laptops are not grounded. You might want to try a desktop (but also check that the wall plugs are properly grounded).

But I agree that for an expensive medical device, shocking its users is unacceptable.

I‘m only a participant, not one of the organizers but even then, the laptop was provided with the device by the company to be used together, I would assume that simply for support and data integrity reasons they are not interested in using a different PC.
