ABSTRACT:
A device for controlling flow rate in an intravenous line comprises a housing having an inlet port adapted to be connected to an incoming segment of an intravenous line and an outlet port adapted to be connected to an outgoing segment of the intravenous line. A valve is disposed in the housing between the inlet port and the outlet port. The device further comprises a first valve adjustment mechanism mounted to the housing and operatively connected to the valve for setting the valve to select a desired flow rate, the first valve adjustment mechanism being manually adjustable for selecting the desired flow rate. A second valve adjustment mechanism is mounted to the housing and is operatively connected to the valve for automatically and temporarily closing the valve in response to the exceeding of the desired flow rate by an average flow rate of intravenous fluid into the housing through the inlet port.
