An infusion system fully compliant with international standard ISO 80639-1, Small-bore Connectors for Liquids and Gases in Healthcare Applications, yet compatible with a multipurpose infusion pump to enable operational redeployment of the pump. An attachment set, removably couplable to the pump inlet and outlet, includes a coded attachment set outlet connector detachably coupling the attachment set to an infusion set, and a coded attachment set pump fitting coupling the attachment set to the infusion pump, thereby identifying to the pump a particular infusion route.
