1. A stable flow regulator assembly comprising:
a body comprising:
a tube slot disposed adjacent a perimeter of the body, the tube slot having an opening at the perimeter to slidingly receive a portion of an intravenous (IV) tube; and
a spiral slide groove extending into the body from the tube slot, wherein a width of the spiral slide groove narrows as the spiral slide groove extends further into the body; and
a tube arm rotatingly coupled to the body, the tube arm having a slot open to the perimeter of the body and configured to slidingly receive the IV tube when the slot is aligned with the tube slot of the body,
wherein the stable flow regulator assembly is configured to regulate a flow rate of fluid flowing through the IV tube based on an amount of compression of the IV tube due to a position of the IV tube within the spiral slide groove.
