Abstract
The gravity flow fluid path for administering IV fluids to a patient is disclosed in which multiple IV fluids can be delivered at different flow rates to the patient without having to replace the administration set up.
Claims16
A gravity flow fluid path for administering fluids intravenously to a patient that includes
- a main flow line having a penetrating means at the top end of said line for coupling said line to a fluid container, and an injection means at the bottom end of said line for intravenously introducing fluid to a patient,
- a mini-drip chamber mounted in said main flow line for administering fluids passing through said mini-drip chamber at a medically low flow rate,
- a shunt flow line connected into the main flow line by an upper connector located above said first regulating means and by a lower connector located below said first regulating means,
- An adult drip chamber mounted in said shunt flow line for administering fluids passing through said adult drip chamber at a medically high flow rate, and
- a first control means associated with said lines that is operable to selectively route fluid in transit through said mini-drip chamber and said adult drip chamber, a second control means associated with said lines that is operable to selectively route one fluid or two fluids concurrently through said lines.

A gravity flow path for administering fluids intravenously to a patient that includes:
- a main flow line having a spike means at the top end thereof for coupling the line to a fluid container and an injection means at the bottom end thereof for intravenously administering fluid to a patient;
- a burette connected into the main flow line having an air vent for allowing ambient air to enter the burette;
- a main drip chamber connected to a bottom outlet to the burette for regulating the flow of fluid through the main line;
- a shunt flow line connected into the main flow line by an upper connector located above the burette and by a lower connector located below the mini-drip chamber;
- an adult drip chamber connected into the shunt line for regulating the flow of fluid through said shunt line whereby fluids can pass through said main line at a medically low flow rate and said shunt line at a medically high flow rate;
- control means mounted in said main flow line that is operable to selectively enable one fluid to be administered or two fluids to be simultaneously administered,
- a first one-way check valve mounted in the main flow line between the mini-drip chamber and the lower connector;
- a second one-way check valve mounted in the shunt flow line between the adult drip chamber and the lower connector;
- and
- a third one-way check valve mounted in the main flow line between the burette and the upper connection.
