1. A stable flow regulator assembly for regulating fluid flow, comprising:
a body comprising:
a first side configured to be coupled to a second side;
a first and second gear mount aligned on an axis between the first side and second side;
a tube pathway configured to receive and retain a tube extending through the body;
a worm gear comprising a gear thread and configured to be rotationally positioned through the first and second gear mount along the axis; and
an actuator configured to be positioned within, and moveable relative to, the body, the actuator comprising teeth configured to engage the gear thread and a tube slot,
wherein the body and the actuator are configured to receive the tube without extending an end of the tube through the tube pathway and the tube slot, and rotation of the worm gear translates to movement of the actuator within the body to move the actuator from an open configuration, wherein the regulator permits fluid flow, to a closed configuration, wherein the regulator restricts fluid flow.
