Abstract

A battery backup system is provided for use in a sedation and analgesia system. The battery backup system can include a battery, a power source, and a battery controller connected to power source and the battery. The power source can be connected to the battery controller unidirectional. In addition, the battery can be connected to the battery controller bidirectional. The battery controller can help determine whether the sedation and analgesia system should be run with the power source or the battery.

Claims

1. A battery backup system for a sedation and analgesia system, said battery backup system comprising:

a. a battery;

b. a power source; and

c. a battery controller connected to said power source and said battery wherein said battery controller determines selection of said battery or said power source.

2. The battery backup system of claim 1 wherein said battery is made of lithium ion.

3. The batter backup system of claim 1 wherein said power source further comprises of an AC power input, an AC/DC converter, and a DC power supply.

4. The battery backup system of claim 3 wherein said AC power input is a 120V wall outlet.

5. The battery backup system of claim 3 wherein said AC/DC converter changes said AC power input to said DC power supply.

6. The battery backup system of claim 1 wherein said power source is connected unidirectional to said battery controller and said battery is connected bidirectional to said battery controller.

7. A battery backup system for a sedation and analgesia system, said battery backup system comprising:

a. a battery;

b. a power source wherein said power source further comprises of an AC power input, an AC/DC converter, and a DC power supply;

c. a battery controller connected to said power source and said battery wherein said battery controller determines selection of said battery or said power source.

8. The battery backup system of claim 7 wherein said battery is made of lithium ion.

9. The battery backup system of claim 7 wherein said AC power input is a 120V wall outlet.

10. The battery backup system of claim 7 wherein said AC/DC converter changes said AC power input to said DC power supply.

11. The battery backup system of claim 7 wherein said power source is connected unidirectional to said battery controller and said battery is connected bidirectional to said battery controller.

12. A method of supplying power to a sedation and analgesia system which comprises:

a. supplying power to said sedation and analgesia system from a power source;

b. checking said power source for a disruption;

c. supplying power to said sedation and analgesia system from a battery if said disruption occurs;

d. switching back to said power source from said battery if said disruption is resolved.

13. A method of supplying power to a sedation and analgesia system recited in claim 12 wherein checking said power source for a disruption further includes sounding an alarm if said disruption occurs.

14. A method of supplying power to a sedation and analgesia system recited in claim 12 wherein supplying power to said sedation and analgesia system from a battery if said disruption occurs further includes checking said battery source for availability.

15. A method of supplying power to a sedation and analgesia system recited in claim 14 wherein checking said battery source for availability further includes shutting down said sedation and analgesia system if said battery source is unavailable.
