Abstract:
1. An IV flow regulator comprising: a housing having an inlet for receiving liquid and an outlet for discharging liquid; a flow control disk; a screw rotatable with respect to the housing and having a lower end that engages an upper surface of the flow control disk to establish a flow rate from the inlet to the outlet, wherein the screw has an off position in which the lower end of the screw deflects the flow control disk to block flow from the inlet to the outlet and has a fully open position in which the lower end of the screw does not deflect the flow control disk so that flow from the inlet to the outlet is unobstructed; a dial connected to the screw for rotating the screw to continuously change the flow rate as the dial and screw rotate, the dial moving through approximately 360 degrees between the off position and the fully open position while the screw moves through the one full rotation; and a stop extending upward from the housing to engage the dial to define the off position and the fully open position.
