Two site infusion apparatus
First Claim
1. An apparatus for use in delivering medication to separate locations from a single source of medication, comprising:
- a valve housing defining an inlet for receiving the medication from the single source of medication and defining first and second outlets of substantially equal flow capacity for delivering the medication to the separate locations in substantially equal amounts, said valve housing having a longitudinal axis and said outlets being spaced from and parallel to said longitudinal axis;
a cap having an open end coupled to said valve housing;
a flexible diaphragm disposed between said cap and said valve housing to define a pressure chamber in fluid communication with said inlet and said outlets, said flexible diaphragm movable between a closed position to seal said pressure chamber from said outlets and an open position to open said pressure chamber to said outlets;
a biasing mechanism operable between said cap and said flexible diaphragm for biasing said flexible diaphragm towards said closed position, said biasing mechanism being disposed about said longitudinal axis;
a pair of flexible tubes elongated between proximal and distal ends, each of said proximal ends coupled to one of said outlets for conveying the medication from said outlets to the separate locations; and
a pair of connectors, each of said connectors coupled to one of said flexible tubes at said distal ends thereof.

Abstract
An apparatus for use in delivering pain medication to separate locations from a single source of pressurized medication includes a valve housing, a cap, and a flexible diaphragm. The valve housing includes a first end and a second end and an inlet passage. The first end includes first and second outlet orifices. The cap has a closed end and an open end and is removably coupled to the valve housing at the open end. The flexible diaphragm is coupled between the cap and the valve housing and is movable from a closed position to an open position. The flexible diaphragm seals a pressure chamber from the first and second outlet orifices when in the closed position and opens the first and second outlet orifices to the pressure chamber when in the open position.
