Abstract

An injection device (120) used in delivering medical fluids to a patient is provided. The injection device (120) may include a syringe plunger driver (126a) and a syringe (140). The syringe (140) may include a syringe data storage device (134). The injection device (120) may include a communication device (132a) disposable in each of attached and detached conditions. The communication device (132a) may be operable to read a data storage device (134) within its field of view. When the communication device (132a) is attached to the injection device (120) and the syringe (140) is installed on the injection device (120), the communication device (132a) may be operable to read the data storage device (134) associated with the syringe (140). When in a detached condition, the communication device (132a) may be operable to be hand manipulated such that various other data storage devices (134) may be read.

Claims

1. A method of operation of a medical fluid delivery system, said method comprising:

reading a first data storage device with a communication device, wherein said reading step comprises hand-maneuvering said communication device proximate to said first data storage device and relative to an injection device;

attaching said communication device to said injection device after said reading a first data storage device step;

installing a syringe on said injection device after said attaching step, wherein said syringe comprises a syringe data storage device; and

reading said syringe data storage device with said communication device while said syringe is installed on said injection device and while said communication device is attached to said injection device.

2. The method of claim 1, wherein said first data storage device is attached to a patient and said reading a first data storage device step comprises moving said communication device proximate to said patient.

3. The method of claim 1, further comprising detaching said communication device from said injection device prior to said reading a first data storage device step.

4. The method of claim 1, further comprising reading a tubing set data storage device with said communication device.

5. The method of claim 4, further comprising setting a pressure limit based on data read during said reading a tubing set data storage device step.

6. The method of claim 1, further comprising storing data, in said communication device, acquired during said reading a first data storage device step prior to said attaching step.

7. The method of claim 1, further comprising recharging a battery of said communication device while said communication device is attached to said injection device.

8. The method of claim 1, further comprising verifying medical fluid from said syringe is appropriate for injection into a patient, wherein said verifying step takes into account data read from said first data storage device and said syringe data storage device.

9. The method of claim 1, further comprising wirelessly transferring data from said communication device to said injection device.

10. The method of claim 1, wherein said attaching step comprises interconnecting said communication device to said injection device via at least one conductive pathway.

11. The method of claim 1, further comprising transferring data from said communication device to said injection device while said communication device is attached to said injection device.

12. The method of claim 1, further comprising reading an operator data storage device with said communication device.

13. The method of claim 12, wherein said reading an operator data storage device step comprises downloading an injection protocol from said operator data storage device to said communication device.

14. The method of claim 13, further comprising executing said injection protocol to discharge medical fluid from said syringe.

15. The method of claim 12, further comprising selecting an injection protocol from a plurality of injection protocols resident in said injection device based at least in part on data obtained from said operator data storage device.
