Abstract

An improved intravenous metering device (1a) having a measuring chamber (77) for use in measuring the discharge pressure of fluid exiting the device (1) is disclosed. The discharge pressure measuring chamber (77), which operates in conjunction with a pin (63) and flexure beam (65) arrangement to provide an indication of fluid discharge pressure, is incorporated into the fluid flow path through the device in order to permit sweeping of gas bubbles from the chamber (77) during device priming operations. Thus, complete removal of gas bubbles from the device (1a) prior to employing the device with a patient is more easily attainable.
