	The idea is for the following medical devices to work like a hybrid of the old brute packs and tend wounds,
	they heal a little at a time, have reduced healing density and does not allow for rapid healing while in combat.
	However they provice graunular control of where the healing is directed, this makes them better for curing work-related cuts and scrapes.

	The interesting limb targeting mechanic is retained and i still believe they will be a viable choice, especially when healing others in the field.
