Infusion

An infusion is a device that slowly injects fluid into a blood vessel. The infusion has a number of components. The infusion contains: the (peripheral) cannula or the (central) catheter put into the patient peripherally or centrally; the administering system connected to the cannula/catheter allowing the administered fluid to run; the infusion bag containing the fluid. Multiple administering systems may be connected to one cannula/catheter. Furthermore, a central venous catheter may have multiple lumens. Arterial and epidural catheters also exist in addition to venous catheters.
