Additional devices for infusion generally include tees, extension tubes, heparin caps, needleless connectors, filters, etc. To reduce infection, the use of additional infusion devices should be minimized. The infusion attachment device should use a spiral interface or an integrated design to ensure safe connection, reduce operations, and minimize the risk of disconnection. Before infusion and injection of medicinal solution at the infusion joint (or interface), 70 ethanol-chlorhexidine and 5 ethanol should be used to wipe the cross-section and periphery of various joints (or interfaces) for more than 15 seconds.
