Basically, 2 items and one new bodypart. Infusions would reduce the most severe illness or infection by 1 severity, but be ridiculously expensive for extended use--like 500, and the NIS would be like bionic body parts but grant a bonus to filtering and thus to recovery. The infusion could also possibly be used to recover from injuries in emergencies.
Check those 2 mods maybe (they do that) :
