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.

Claims

1. A method of delivering fluid media to a plurality of patients, comprising:

delivering a first fluid medium through a reusable fluid path;

delivering the first fluid medium through a per-patient disposable fluid path;

disconnecting the per-patient disposable fluid path from the reusable fluid path;

disposing the per-patient disposable fluid path; and

connecting a second per-patient disposable fluid path to the reusable fluid path.

2. The method of claim 1, further comprising:

delivering the first fluid medium through the reusable fluid path and the second per-patient disposable fluid path;

disconnecting the second per-patient disposable fluid path from the reusable fluid path; and

disposing the second per-patient disposable fluid path.

3. The method of claim 1 wherein the reusable fluid path comprises a source of the first fluid medium and a pressurizing unit.

4. The method of claim 1 wherein the per-patient disposable fluid path comprises a valve and a tube.
