1. A device comprising:
- a piece of tubing having a radial axis; and
an occluder mechanism having a body with a portion disposed outside the tubing, a stop disposed in the tubing to prevent fluid flow through the tubing, and an actuator disposed to forcefully engage and deform the tubing and open a flow channel around the stop;
wherein the actuator has at least one arm disposed outside of the tubing and pivotable relative to the radial axis of the tubing, the at least one arm having a curvature about the stop;
wherein a concentric mating arrangement is formed between the at least one arm and the stop, the concentric mating arrangement defining an annular passage for coaxially receiving the piece of tubing;
wherein the at least one arm and the stop are physically connected via the portion of the body disposed outside the tubing.

Abstract
An anti-free-flow mechanism includes an occluder mechanism which is disposed along a segment of tubing and a mounting structure. The occluder mechanism is normally in a biased closed position, but may be moved into an open position by placement in the mounting structure. However, unless force is applied to keep the occluder mechanism in the mounting structure, the occluder will move relative to the mounting structure and return to the first, closed position.

19. A method for controlling fluid flow through tubing, the method comprising:
-
selecting a tubing having an occluder with a body with a portion disposed outside the tubing, a stop disposed in the tubing, and an actuator extending along the tubing adjacent the occluder; and pressing on the actuator to forcefully engage the tubing and deform the tubing to open a fluid flow channel; wherein the actuator has at least one arm disposed outside of the tubing and pivotable relative to a radial axis of the tubing, the at least one arm having a curvature about the stop; wherein a concentric mating arrangement is formed between the at least one arm and the stop, the concentric mating arrangement defining an annular passage for coaxially receiving the piece of tubing; wherein the at least one arm and the stop are physically connected via the portion of the body disposed outside the tubing. - View Dependent Claims (20, 21, 22, 23, 24)
