ABSTRACT:
A compact, integrated intravenous fluid delivery device. In one embodiment, the invention may be used with first and second intravenous fluid sources and an intravenous fluid line. This embodiment includes a spike for connecting the device to the first intravenous fluid source. A fluid passageway passes through the spike. A connection site (e.g. a puncture site) connects the device to the second intravenous fluid source. This embodiment also includes a drip chamber, through which the fluid may flow to the intravenous fluid line. This embodiment may include an adjustable valve, which includes a flexible tube mounted so that fluid may pass from the fluid passageway in the spike, from the connection site, and through the tube. The valve includes an actuator mounted with respect to the tube so that it may be urged to compress the tube. The spike, the adjustable valve, and the drip chamber are rigidly attached to each other, with no flexible tubing between the various components. This embodiment may further include a one-way valve mounted below the spike and above the connection site, so that intravenous fluid may flow from the fluid passageway through the one-way valve, and so that fluid from the second fluid source may flow to the intravenous fluid line, but may not flow through the fluid passageway in the spike.
