Abstract

A battery system for a medical device includes a first power supply and a second power supply. The first power supply is capable of being connected to the medical device to supply power to the medical device during a first operating mode of the medical device. The second power supply supplies power to at least one of a portion of the medical device and the battery system during an alternate mode, exclusive of a state the first power supply.

Claims

1. A battery system for a medical device, the battery system comprising:

a first power supply capable of being connected to the medical device, wherein the first power supply powers at least a portion of the medical device during a first operating mode of the medical device; and

a second power supply, wherein the second power supply powers at least one of a portion of the medical device and the battery system during an alternate mode, exclusive of a state the first power supply.

2. The battery system of claim 1 wherein the first power supply powers essential power needs of the medical device.

3. The battery system of claim 1 wherein the second power supply powers non-essential power needs of the medical device.

4. The battery system of claim 3 wherein the non-essential power needs comprises reporting a status of the medical device.

5. The battery system of claim 3 wherein the non-essential power needs comprises sounding an enunciator.

6. The battery system of claim 3 wherein the non-essential power needs comprises running a self-test routine.

7. The battery system of claim 3 wherein the non-essential power needs comprises electric circuitry of at least a portion of at least one of the battery system and the medical device.

8. The battery system of claim 7 wherein the electric circuitry includes a memory device.

9. The battery system of claim 7 wherein the electric circuitry includes digital logic.

10. The battery system of claim 7 wherein the electric circuitry includes electronically erasable programmable read only memory.

11. The battery system of claim 3 wherein the non-essential power needs comprises at least one visual indicator.

12. The battery system of claim 11 wherein the visual indicator comprises a light emitting diode.

13. The battery system of claim 1 wherein the second power supply is replaceable.

14. The battery system of claim 1 wherein the first power supply comprises a plurality of battery cells.

15. The battery system of claim 1 wherein the medical device comprises an external defibrillator.

16. The battery system of claim 1 wherein the battery system is capable of being removed from the medical device.

17. A method of powering components of a medical device, the method comprising:

powering at least a portion of the medical device with a first power supply during a first operating mode of the medical device; and

powering at least a portion of the medical device with a second power supply during an alternate mode, exclusive of a state the first power supply.

18. The method of claim 17 wherein the first power supply powers essential power needs of the medical device.

19. The method of claim 17 wherein the second power supply powers non-essential power needs of the medical device.

20. The method of claim 19 wherein the non-essential power needs comprises reporting a status of the medical device.

21. The method of claim 19 wherein the non-essential power needs comprises sounding an enunciator.

22. The method of claim 19 wherein the non-essential power needs comprises running a self-test routine.

23. The method of claim 19 wherein the non-essential power needs comprises electric circuitry of at least a portion of at least one of the battery system and the medical device.

24. The method of claim 23 wherein the electric circuitry includes a memory device.

25. The method of claim 23 wherein the electric circuitry includes digital logic.

26. The method of claim 23 wherein the electric circuitry includes electronically erasable programmable read only memory.

27. The method of claim 19 wherein the non-essential power needs comprises at least one visual indicator.

28. The method of claim 27 wherein the visual indicator comprises a light emitting diode.

29. The method of claim 17 wherein the second power supply is replaceable.

30. The method of claim 17 wherein the first power supply comprises a plurality of battery cells.

31. The method of claim 17 wherein the medical device comprises an external defibrillator.

32. The method of claim 17 wherein the first power supply and the second power supply comprise a battery system that is capable of being removed from the medical device.
