Abstract
The present invention describes IV regulators that allow interruption of normal controlled-flow for a safe and convenient bolus flush, either for a specific period of time or for a specific volume of saline flush. Two time-controlled IV regulators are shown, one employing a pneumatic cylinder counter-opposed by elastic band(s) for administering a bolus flush, and one employing a compressible lever and torsion spring counter-opposed by a rotary damper. In both cases the mechanisms disengage the roller-clamp from the IV tube for a predetermined amount of time to fully open fluid flow there through for a bolus flush before return to the regulated-flow position. The volume-controlled flow regulator employs two internal bladders and allows one bladder to fill while the other bladder drains (and vice versa) by flipping a slider paddle-type toggle, thus enabling the administration of a set volume of flush fluid.
