Abstract

An infusion set component of a fluid infusion device and/or a fluid infusion port component for delivery of fluid to a patient is compatible with a cooperating fluid channel module. The fluid channel module includes a body section having coupling features to mate with a base of the component. The fluid channel module also includes an interior fluid flow channel formed within the body section to receive fluid from the fluid infusion device and/or from a syringe or pen delivery device. The fluid channel module also includes a conduit having a first end in fluid communication with the interior fluid flow channel, and having a second end to deliver the fluid to the patient.
