Abstract

A patient position-activated room device control apparatus coupled to a patient'"'"'s bed controls a device associated with a patient'"'"'s room in response to the patient changing position relative to the patient'"'"'s bed.

Claims

1. A bed system, comprising

a bed,

a bed exit monitor coupled to the bed, the bed exit monitor being operable to detect a patient exiting the bed, and

a controller coupled to the bed exit monitor and to lighting configured to illuminate at least a portion of a room in response to being turned on, the lighting configured to be turned on by a manually operated switch, the controller being configured to receive a first signal from the bed exit monitor and use the first signal to control the turning on or off of the lighting independently of the manually operated switch.

2. The bed system of claim 1, comprising a detector coupled to the controller, the detector being configured to determine whether the lighting has been turned on or off via the manually operated switch, the controller being configured to receive a status signal from the detector, the status signal indicating whether the lighting is turned on or off.

3. The bed system of claim 2, wherein the controller is configured to turn on the lighting if the first signal indicates that the patient has exited the bed and the status signal indicates that the lighting is turned off.

4. The bed system of claim 3, wherein the controller is configured to enable the lighting to remain turned on if the first signal indicates that the patient has exited the bed and the status signal indicates that the lighting is turned on.

5. The bed system of claim 1, wherein the controller is configured to receive a second signal from the bed exit monitor and use the second signal to control the turning off of the lighting independently of the manually operated switch.

6. The bed system of claim 5, wherein the bed exit monitor is configured to detect a patient having entered the bed and the second signal indicates that the patient has entered the bed.

7. The bed system of claim 6, wherein the controller is configured to enable the lighting to turn off if the second signal indicates that the patient has entered the bed and the status signal indicates that the lighting has been turned off via the manually operated switch.

8. The bed system of claim 1, wherein the controller is configured to generate an alert signal indicating whether the lighting is turned on or turned off in response to signals from the bed exit monitor.

9. The bed system of claim 1, comprising an output device configured to display an indication of whether the lighting is turned on or turned off.

10. The bed system of claim 1, comprising an input device coupled to the controller, wherein the input device is configured to receive an input signal, and the controller is configured to use the input signal to enable or disable the turning on and turning off of the lighting in response to signals from the bed exit monitor independently of the manually operated switch.

11. The bed system of claim 1, comprising a connector coupled to the controller, wherein the connector is configured to couple the controller to a healthcare communication system.

12. The bed system of claim 11, wherein the controller is configured to send an alert signal to the healthcare communication system if the lighting is turned on or off in response to signals from an ambient light detector.

13. The bed system of claim 12, wherein the healthcare communication system is a nurse call system.

14. The bed system of claim 1, wherein the lighting is spaced from the bed.

15. The bed system of claim 1, wherein the lighting is coupled to the bed.

16. A room lighting control apparatus for use in connection with a room in which a bed usable by a patient is located, the room lighting control apparatus comprising:

a controller configured to receive a position signal corresponding to the patient'"'"'s position relative to the bed, use the position signal to determine whether to turn on lighting in the patient'"'"'s room, the lighting being configured to provide illumination in the patient'"'"'s room, and send a lighting control signal to the room lighting to turn on the room light if the patient has exited the bed.

17. The room lighting control apparatus of claim 16, wherein the controller is configured to determine, from the position signal, whether the patient has exited the bed.

18. The room lighting control apparatus of claim 16, wherein the controller is configured to determine whether the room lighting is turned on.

19. The room lighting control apparatus of claim 18, comprising a detector coupled to the controller, wherein the controller is configured to receive a status signal from the detector, the status signal indicating whether the room lighting is turned on.

20. The room lighting control apparatus of claim 19, wherein the lighting control signal is configured to enable the room lighting to remain turned on if the status signal indicates that the room lighting is turned on.

21. The room lighting control apparatus of claim 16, wherein the controller is configured to receive a second position signal and send a second room lighting control signal to the room lighting to turn off the room lighting if the second position signal indicates that the patient is positioned on the bed.

22. A room device control apparatus for use in connection with a room comprising a bed usable by a patient, a first room device, and a second room device, the room device control apparatus comprising:

a controller configured to receive a position signal corresponding to the patient'"'"'s position relative to the bed, use the position signal to determine whether to turn on at least one of the first room device and the second room device, the first and second room devices being configured to provide output in or adjacent to the patient'"'"'s room, the first and second room devices each being activatable by a manually operated switch, the controller being configured to send a room device control signal to at least one of the first room device and the second room device to turn the at least one of the first room device and the second room device on or off in response to the patient changing position relative to the bed, independently of the manually operated switch, and

a conduit coupling the controller to the first and second room devices.

23. The room device control apparatus of claim 22, wherein the conduit includes a wireless communication link.
