Abstract
An apparatus and method enabling the injection of fluid media into a plurality of patients is provided, including a fluid supply source providing multiple doses, a metering device for measuring the doses, a pressurizing device to effect injection, a contamination prevention device disposed between the fluid source and the patient and, when desired, an electronic control device to integrate operation of the apparatus and process.
Claims44
A fluid delivery system comprising:
- a reusable fluid path apparatus for delivering fluid to multiple patients, the reusable fluid path apparatus comprising:
- a first source of fluid medium;
- a second source of fluid medium;
- a pressurizing unit operably associated with the first source of fluid medium for delivering the first fluid medium to multiple patients;
- and
- a pump operably associated with the second source of fluid medium for delivering the second fluid medium to multiple patients;
- and
- a per-patient disposable fluid path operable to deliver the first fluid medium and the second fluid medium to a patient during an injection procedure, the per-patient disposable fluid path comprising:
- a valve;
- a tube;
- and
- a connector adapted to connect the per-patient disposable fluid path to the reusable fluid path apparatus;
- wherein the per-patient disposable fluid path is connected to the reusable fluid path apparatus before the first fluid medium and the second fluid medium are delivered to the patient and is disconnected from the reusable fluid path apparatus after the first fluid medium and the second fluid medium are delivered to the patient and the injection procedure for the patient is completed.
