Abstract

A method and medical pump to perform a flushing procedure are provided. The medical pump is configured to execute the flushing procedure subsequent to an infusion procedure, the flushing procedure and infusion procedure lacking a specified relationship between each other until after performance of the infusion procedure. The method comprises performing an infusion procedure of a medicament with the medical pump and automatically querying in human detectable form whether to execute a flushing procedure in response to conclusion of the infusion procedure.

Claims

1. A method of flushing a fluid line with a medical pump configured to execute a flushing procedure subsequent to an infusion procedure, the method comprising:

automatically querying in human detectable form whether to proceed with the flushing procedure in response to conclusion of the infusion procedure, the flushing procedure lacking a specified relationship with the infusion procedure until after performance of the infusion procedure.

2. A method of flushing a fluid line with a medical pump configured to execute a flushing procedure, the method comprising:

performing the flushing procedure with a flushing fluid to flush the fluid line;

stopping the flushing procedure before it is completed; and

automatically querying in human detectable form whether to restart the flushing procedure after it has been stopped.

3. The method of claim 2 further comprising restarting the flushing procedure in response to a determination to restart the flushing procedure.

4. The method of claim 3 further comprising restarting the flushing procedure with at least one altered setting.

5. The method of claim 2 further comprising canceling the flushing procedure.

6. A method of tracking volume of medicament infused by a medical pump configured to expel medicament into a fluid line comprising:

determining a volume of medicament expelled into the fluid line during an infusion procedure; and

increasing the volume of medicament expelled by an amount equal to a volume of flushing fluid expelled into the fluid line during a flushing procedure after conclusion of the infusion procedure, whereby to have a total volume of medicament infused by the medical pump.

7. The method of claim 6 further comprising displaying the total volume of medicament infused.

8. The method of claim 6 further comprising separately determining the total volume of flushing fluid expelled during the flushing procedure.

9. The method of claim 8 further comprising separately displaying both the total volume of medicament infused and the total volume of flushing fluid expelled.

10. A medical pump comprising:

at least one processing unit; and

a memory containing program code configured to, when executed by the at least one processing unit, automatically query in human detectable form whether to proceed with a flushing procedure in response to conclusion of an infusion procedure, the flushing procedure lacking a specified relationship with the infusion procedure until after performance of the infusion procedure.

11. A medical pump comprising:

at least one processing unit; and

a memory containing program code configured to, when executed by the at least one processing unit, perform a flushing procedure with a flushing fluid to flush a fluid line, stop the flushing procedure before it is completed, and automatically query in human detectable form whether to restart the flushing procedure after it has been stopped.

12. The medical pump of claim 11, the program code further configured to restart the flushing procedure in response to a determination to restart the flushing procedure.

13. The medical pump of claim 12, the program code further configured to restart the flushing procedure with at least one altered setting.

14. The medical pump of claim 11, the program code further configured to cancel the flushing procedure.

15. A medical pump comprising:

at least one processing unit; and

a memory containing program code configured to, when executed by the at least one processing unit, determine a volume of medicament expelled into a fluid line during an infusion procedure and increase the volume of medicament expelled by an amount equal to a volume of flushing fluid expelled into the fluid line during a flushing procedure after conclusion of the infusion procedure, whereby to have a total volume of medicament infused by the medical pump.

16. The medical pump of claim 15, the program code further configured to display the total volume of medicament infused.

17. The medical pump of claim 15, the program code further configured to separately determine the total volume of flushing fluid expelled during the flushing procedure.

18. The medical pump of claim 15, the program code further configured to separately display both the total volume of medicament infused and the total volume of flushing fluid expelled.
