Abstract
An intravenous fluid therapy system includes a source of intravenous fluid which is an intravenous-fluid-filled non-vented container having deformable side walls. Pressure means substantially surrounds the side walls of the source to pressurize the intravenous fluid therein. The pressure means includes tensioning means to cause the pressure means to exert a force against the side walls. An airless flow meter receives intravenous fluid from the source by a tube means. The airless flow meter includes flow indication means which may be a plurality of fins symmetrically secured to a hub rotatably mounted within a non-vented chamber. An outlet from the flow meter is connected by tube means to an intravenous catheter. In operation, the source is pressurized to allow intravenous fluid to flow through the tube means and the airless flow meter and out the catheter to urge all air therefrom. The pressure means maintains a fluid head to force the fluid from the source through to the catheter means without venting during intravenous fluid administration.
