IV apparatus
First Claim
1. A gravity flow fluid path for administering fluids intravenously to a patient that includesa 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, anda 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.

1. 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.

10. 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. - View Dependent Claims (11, 12, 13, 14, 15, 16)
