Abstract

Systems, apparatus and methods are provided through which an injector system automates a process of injecting an individual dose from a multiple dose of a radiotracer material. In some embodiments, the injector system includes a first dose calibrator system that receives a multidose vial of a radiotracer, a second dose calibrator system, an injection pump and an intravenous needle. In some embodiments, the first dose calibrator system and the multidose vial have an integrated shape. In some embodiments, the first dose calibrator system includes a pneumatic arm that receives the multidose vial.

First claim

We claim:

1. A method of preparing an injector system for use by a number of patients, the method comprising:
activating a computer system;
delivering a multidose vial of a radiopharmaceutical to the injector system, wherein the injector system is controlled by the computer system and the multidose vial is configured to dispense multiple doses of the radiopharmaceutical to corresponding multiple patients; and
moving the multidose vial into a dose calibrator system of the injector system, wherein moving the multidose vial into the dose calibrator system comprises positioning the multidose vial beneath the injector system, and raising the mutlidose vial from a container from outside the injector system with an automated arm into the dose calibrator system.

2. The method of claim 1 , wherein the activating is performed before the delivering.

3. The method of claim 1 , wherein the radiopharmaceutical further comprises nitrogen-13 ammonia.

4. The method of claim 1 , wherein the radiopharmaceutical further comprises fluorodeoxyglucose.

5. The method of claim 1 , wherein the container is a shipping container in which the multidose vial was delivered to a site of the injector system.

6. The method of claim 1 , further comprising extracting an individual dose from the multidose vial into a patient vial.

7. The method of claim 6 , further comprising delivering the individual dose from the patient vial to a syringe for delivery to a patient.

8. The method of claim 6 , further comprising determining if an amount of radioactivity in the patient vial equals an amount of radioactivity removed from the multidose vial, and, if so, adding saline to the patient vial.
