Title of the Invention ELECTRONICALLY CONTROLLED INTRAVENOUS INFUSION SET Abstract of the Invention An electronically controlled, gravity-feed, intravenous infusion set in which a length of intravenous tubing is connected with a drip chamber to convey a fluid to be administered intravenously, the improvement comprising a normally closed internal valve in said set operable to prevent flow of fluid through the set and operated to open position to enable passage of a drop of fluid through the set, and an electrically controlled actuator operatively associated with the valve to operate the valve to its open position at a predetermined frequency of operation and to hold the valve open until a drop forms and falls to thus determine the drip rate of fluid through the set, said internal valve thus enabling control of flow of fluid through the set without necessitating crimping or other deformation of the set and thereby resulting in dependable and accurate control of the flow rate of the fluid to be administered intravenously.
