1. A system comprising:
- a fluid port comprising;
a fluid channel;
a fluid inlet at a first end of the fluid channel configured to couple to an outlet of a manually administrable fluid source;
a fluid outlet at a second end of the fluid channel configured to deliver fluid from the manually administrable fluid source to a fluid pathway that provides fluid to a patient;

a flow controller in communication with the at least one sensor that generates at least one flow modification signal in response to the determined at least one attribute matching at least one condition specified by at least one rule; and
a flow control valve in communication with the flow controller and positioned within the fluid pathway at a location separate and distinct from the fluid port, the flow control valve changing a level of flow restriction of the fluid from the manually administrable fluid source passing therethrough in response to receiving the at least one flow modification signal, wherein changing the level of flow restriction of the fluid from the manually administrable fluid source passing through the flow control valve comprises adjusting a current flow rate of the fluid passing through the flow control valve to a higher or lower flow rate, wherein the flow control valve partially restricts the fluid passing through the flow control valve at the higher or lower rate,wherein the at least one sensor is configured to automatically measure a withdrawn downstream fluid volume, wherein the withdrawn downstream fluid volume is a total volume of the fluid downstream of the fluid inlet and still within the fluid channel after fluid flow through the fluid pathway is stopped, andwherein the at least one sensor comprises a fluid flow sensor, and wherein sensed fluid flow information causes the flow controller to generate a first flow modification signal to cause the flow control valve to transition to a first state when a first pre-determined volume has been delivered as measured by the fluid flow sensor, and after a pre-determined span of time, causes the flow controller to generate a second flow modification signal to cause the flow control valve to transition to a second state different than the first state.

Abstract
Systems and methods for controlling fluid delivery via a manually administrable medication container to a patient through a fluid delivery pathway are provided. The systems and methods described herein incorporate rules-based clinical decision support logic to drive a flow control valve within a flow pathway based on a determination of whether or not an IV fluid connected to an input port on the pathway is appropriate for patient administration by considering such factors as patient-specific clinical circumstances, current medical orders, and accepted delivery protocols. Related apparatus, systems, methods and articles are also described.
