Abstract

A system for the effective, reliable and foolproof delivery of controlled amounts of a medical fluid to a patient is provided. The system includes an integrated compressed gas unit having an inlet port to which at least one compressed gas cylinder is selectively connected and an outlet port in communication with the inlet port. The integrated compressed gas unit also includes a regulator valve assembly positioned between the outlet port and the inlet port, wherein the regulator valve assembly includes a press button actuator and regulator adjustment dial. The system also includes a flow control system delivering the fluid in precisely controlled amounts.

Claims

1. A system for the effective, reliable and foolproof delivery of controlled amounts of a medical fluid to a patient, comprising:

an integrated compressed gas unit including an inlet port to which at least one compressed gas cylinder is selectively connected and an outlet port in communication with the inlet port, the integrated compressed gas unit also including a regulator valve assembly positioned between the outlet port and the inlet port, wherein the regulator valve assembly includes a press button actuator having a push button mechanism permitting a user to selectively determine when medical fluid is to pass through the outlet port and regulator adjustment dial that is rotated to adjust the pressure of the medical fluid exiting the compressed gas unit, the integrated compress gas unit further includes a cylinder cartridge puncture valve and a fitting formed at the inlet port of the integrated compressed gas unit for holding or securing the compressed gas cylinder in place; and

a flow control system delivering the fluid in precisely controlled amounts.

2. The system according to claim 1, wherein the outlet port is provided with a Luer connection for the secure and selective attachment of an outlet tube thereto, the outlet tube being connected to the flow control system.

3. The system according to claim 1, wherein the flow control system includes an inlet conduit for being communicably joined to the integrated compressed gas unit;

an outlet conduit for being communicably joined to the patient;

first and second syringes intermediate the inlet and outlet conduits; and

a control valve assembly interconnecting the inlet conduit, the outlet conduit, the first syringe and the second syringe.

4. The system according to claim 3, wherein the control valve assembly is alternatable between a first state wherein the inlet conduit communicates with the first syringe for transmitting fluid from the integrated compressed gas unit to only the first syringe, a second state wherein the first syringe communicates only with the second syringe and is isolated from the inlet and outlet conduits for transmitting fluid from the first syringe to only the second syringe, and a third state wherein the second syringe communicates only with the outlet conduit and is isolated from the inlet conduit and the first syringe for transmitting fluid from the second syringe to only the outlet conduit.

5. The system according to claim 4, wherein the control valve assembly includes a valve body having aligned inlet and outlet ports, the inlet port being communicably connectable to the inlet conduit and the outlet port being communicably connectable to the outlet conduit, the valve body further including a first intermediate port to which the first syringe is selectively connected and a second intermediate port to which the second syringe is selectively connected, the control valve assembly further including a stopcock element mounted rotatably within the body and including a channel consisting essentially of a first channel segment and a second channel segment, the first and second channel segments being selectively alignable with the inlet port and the first intermediate port to allow for communication between the inlet conduit and the first syringe, the first intermediate port and the second intermediate port to allow for communication between the first syringe and the second syringe, and the second intermediate port and the outlet port to allow for communication between the second syringe and the outlet conduit.

6. The system according to claim 5, wherein the first and second intermediate ports include respective longitudinal axes that form an angle with one another, the first intermediate port forms an angle with a longitudinal axis of the inlet port that is equivalent to the angle formed by the longitudinal axes of the first and second intermediate ports, the longitudinal axis of the second intermediate port forms an angle with a longitudinal axis of the outlet port that is equivalent to the angle formed by the longitudinal axes of the first and second intermediate ports, and the first channel segment and the second channel segment have respective longitudinal axes that form an angle equivalent to the angle formed by the longitudinal axes of the first and second intermediate ports.
