A tube for use in a flow controller of an intravenous or other slow flow control apparatus has a configuration somewhat like the opening defined by the open eyelids of the human eye whereby to provide relatively sharp corners and narrow width of the opening to reduce materially the force required to close relative to that required to close a round tube and to reduce the movement of the flow control element of the controller, which controller is configured to take advantage of the shape of the tube and employs a shape memory control element to adjust rate of flow of the fluid; the controller also including a brake element to lock the flow rate at a particular preselectable rate.
