Delivery system and method for the effective and reliable delivery of controlled amounts of a medical fluid
A method for performing a medical procedure requiring effective, reliable and foolproof delivery of controlled amounts of a medical grade gas to a patient includes providing a compressed gas cylinder having a weight with medical grade gas sealed therein of at least twelve grams and not greater than fifty grams. The method also includes connecting the compressed gas cylinder to an integrated compressed gas unit including a regulator valve assembly positioned between an outlet port and an inlet port, wherein the regulator valve assembly includes a press button actuator and regulator adjustment dial. A flow control system is secured to the compressed gas unit and the medical grade gas is delivered in precisely controlled amounts by actuating the compressed gas unit and operating the flow control system to deliver the medical grade gas to vasculature of the patient.
1. A method for performing a medical procedure requiring effective and reliable delivery of controlled amounts of a medical grade gas to a patient, comprising:
providing a compressed gas cylinder having a weight with medical grade gas sealed therein of at least twelve grams and not greater than fifty grams, the compressed gas cylinder including an elongate, generally cylindrical body having an interior chamber accommodating a compressed and sterile medical grade gas therein, wherein said cylindrical body is of a triple washed construction for holding the medical grade gas within said interior chamber of said cylindrical body under pressure;
connecting the compressed gas cylinder to an integrated compressed gas unit including an inlet port to which the 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 regulator adjustment dial;
securing a flow control system to the compressed gas unit;
delivering the medical grade gas in controlled amounts by actuating the compressed gas unit and operating the flow control system to deliver the medical grade gas.
2. A method for performing a medical procedure according to claim 1 , wherein an end portion of compressed gas cylinder is encircled by a thread for attaching said cartridge to a medical apparatus requiring compressed gas of the type contained by said cartridge.
3. A method for performing a medical procedure according to claim 2 , wherein said thread is at least ¼″ (6.35 mm) and not greater than 1″ (25.4 mm).
4. A method for performing a medical procedure according to claim 1 , wherein the medical grade gas is CO 2 .
5. A method for performing a medical procedure according to claim 4 , wherein the step of delivering includes delivering CO 2 for the purpose of imaging.
6. A method for performing a medical procedure according to claim 4 , wherein the step of delivering includes delivering CO 2 for the purpose of medical diagnosis and therapy.
7. A method for performing a medical procedure according to claim 4 , wherein the step of delivering includes delivering CO 2 for the purpose of apply CO 2 as an alternative to iodinated contrast.
8. A method for performing a medical procedure according to claim 4 , wherein the step of delivering includes delivering CO, for the purpose of acting as a medical device for minimal access vascular procedures.
9. A method for performing a medical procedure according to claim 4 , wherein the step of delivering includes delivering CO 2 for the purpose of in vivo diagnostic use for carrying solutions to stabilize micro bubbles for ultrasound, radiographic or fluoroscopic imaging.
