The present invention includes systems and methods for medical fluid delivery. Such system may comprise a fluid flow path for communication between a fluid source and a patient. A flow valve is operatively associated with the path and movable between a first position, which allows fluid flow through the path, and a second position, which limits fluid flow through the path. A control module is operatively associated with the valve to move the valve between the first and second positions in response to a measured actual fluid flow rate in the path. Such method may comprise flowing a fluid through a fluid flow path between a portable fluid source and a patient; determining an actual fluid flow rate through the path; and changing the actual fluid flow rate in response to a difference between the actual fluid flow rate and a desired fluid flow rate. Such method may further include a plurality of settings for a desired flow rate according to a sensed pain level of the patient.
