OG exemplary drawing
 
1. A medical pumping system, comprising:
a fluid pump comprising:
a fluid inlet connection;
a fluid outlet connection;
an actuator; and
a backing surface;
a tube of an intravenous set disposed between the fluid inlet connection and the fluid outlet connection of the fluid pump, and disposed between the actuator and the backing surface; and
a binding contact interface disposed between the tube and the actuator, the binding contact interface comprising a tubing interface coupled to the tube; and
an actuator interface coupled to the actuator,
wherein the tubing interface comprises a strut sized and shaped to link to the actuator interface, the strut disposed between the tube and the actuator interface,
wherein the tube and the actuator are coupled together by the binding contact interface, and
wherein the actuator is configured to actively pull a portion of the tube into an open position during a pump cycle.
 
8. A medical pumping system, comprising:
a fluid pump comprising:
a fluid inlet connection;
a fluid outlet connection;
an actuator; and
a backing surface;
a tube of an intravenous set disposed between the fluid inlet connection and the fluid outlet connection of the fluid pump, and disposed between the actuator and the backing surface; and
a binding contact interface, wherein the binding contact interface comprises:
at least a portion of the actuator comprising a magnetic inductor; and
at least a portion of the tube is magnetic, wherein the actuator is configured to switch magnetic polarities to alternately attract and repel the magnetic tube portion,
wherein the tube and the actuator are coupled together by the binding contact interface, and
wherein the actuator is configured to actively pull a portion of the tube into an open position during a pump cycle.
 
14. A medical pump, comprising:
a fluid inlet connection;
a fluid outlet connection;
an actuator configured to compress a portion of an intravenous tube, wherein one of:
the actuator is coupled to a first binding contact interface; and
the actuator comprises a first binding contact interface;
a backing surface opposing the actuator, wherein one of:
the backing surface is coupled to a second binding contact interface; and
the backing surface comprises a second binding contact interface,
wherein the first and second binding contact interfaces are configured to couple with first and second portions of the tube, respectively;
an actuator interface coupled to the actuator; and
a tubing interface configured to be coupled to the tube, the tubing interface comprising a strut sized and shaped to link to the actuator interface, the strut disposed between the tube and the actuator interface,
wherein the actuator is configured to actively pull a portion of the tube into an open position during a pump cycle via the coupling of the first binding contact interface to the first portion of the tube, and wherein the backing surface is configured to hold the tube in place during the pump cycle via the coupling of the second binding contact interface to the second portion of the tube.
