Abstract

An alarm system (52) for a medical pump (50) associated with delivering a fluid (54) to a patient in connection with treatment of the patient is provided. The alarm system (52) comprises an alarm (60) associated with at least one treatment parameter. The alarm (60) includes a first alarm state (1) associated with a first event relating to the treatment parameter and a second alarm state (2) associated with a second event. The second alarm state (2) is discernable from the first alarm state (1), which will allow each of the events to be treated differently by a caregiver.

13. The alarm system of claim 10, wherein the second alarm signal has a frequency that is discernable from the first alarm signal.

14. The alarm system of claim 1, wherein the alarm is visual.

15. The alarm system of claim 14, wherein the second alarm signal has an appearance that is discernable from the first alarm signal.

16. The alarm system of claim 1, wherein the alarm has an audible component and a visual component.

18. The alarm system of claim 1, wherein the pump is adapted to shut off when the alarm is in the second alarm state.

20. The alarm system of claim 1, wherein the second alarm state is operational with a particular medicament.

21. The alarm system of claim 20, wherein identification of the particular medicament is adapted to be stored in a memory associated with the pump.

2. An alarm system for a medical pump associated with delivering a medicament to a patient, the alarm system comprising:

at least one computer programmed to operate (i) an alarm associated with at least one treatment parameter, the alarm having a first alarm state associated with a first event relating to the at least one treatment parameter and a first alarm signal, and (ii) a snooze element that deactivates the first alarm state and at the same time sets a second alarm state associated with a second event and a second alarm signal, the second event activating the second alarm state when a predefined amount of time has expired from an occurrence of the first event, the second alarm signal discernable from the first alarm signal.

17. The alarm system of claim 2, wherein the second event is associated with a life-threatening situation for the patient.

19. The alarm system of claim 2, wherein the events can be set by a user.

22. The alarm system of claim 2, wherein the second event relates to the at least one treatment parameter.

23. The alarm system of claim 2, wherein the alarm is perceptive to an operator.

24. The alarm system of claim 2, wherein the at least one treatment parameter is associated with a source external to the pump.

25. The alarm of claim 2, wherein the alarm signals associated with the alarm states are routed to a device external to the pump.

26. An alarm system for a medical pump for delivering a therapeutic fluid to a patient, the alarm system comprising:

at least one computer programmed to operate (i) an alarm associated with at least one operating parameter, the alarm having a first alarm state and a second alarm state, the first alarm state associated with a first alarm signal indicating a non-critical deviation from an original value of the at least one operating parameter, the second alarm state associated with a second alarm signal discernable from the first alarm signal and indicating a critical deviation from the original value of the at least one operating parameter, and (ii) a snooze element that when activated deactivates the first alarm state, enables the second alarm state to be activated upon an occurrence of the critical deviation, and allows the medical pump to continue delivering the medicament to the patient at least until the critical deviation occurs.

27. An alarm system for a medical pump associated with delivering a fluid to a patient in connection with treatment of the patient, the alarm system comprising:
