Abstract

A patient support apparatus includes a bed frame having a head end and a foot end and control circuitry carried by the bed frame. The control circuitry receives information about conditions of the patient support apparatus. A light is coupled to the bed frame adjacent the foot end and is coupled to the control circuitry. The light is in a first state when the patient support apparatus is operating normally and the light is in a second state when the control circuitry detects an alert condition.

Claims

1. A patient support apparatus comprising

a bed frame having a head end and a foot end,

control circuitry carried by the bed frame, the control circuitry receiving information about at least two conditions of the patient support apparatus, and

a light coupled to the bed frame adjacent the foot end and coupled to the control circuitry, the light being in a first state when the patient support apparatus is operating normally and the light being in a second state when the control circuitry detects an alert condition as determined by the control circuitry based on the information, wherein the first state includes the light being illuminated green and wherein the second state includes the light being illuminated a color other than green.

2. The patient support apparatus of claim 1, wherein the alert condition corresponds to a patient'"'"'s amount of motion exceeding a threshold.

3. The patient support apparatus of claim 1, wherein the alert condition corresponds to a patient attempting to exit the patient support apparatus.

4. The patient support apparatus of claim 1, wherein the alert condition corresponds to a patient lying near an edge of the patient support apparatus.

5. The patient support apparatus of claim 1, further comprising a foot board coupled to the bed frame and the light being carried by the foot board.

6. The patient support apparatus of claim 5, further comprising a control panel carried by the foot board above the light.

7. The patient support apparatus of claim 6, wherein the control panel comprises a touch screen.

8. The patient support apparatus of claim 7, further comprising a mattress supported on the bed frame and the touch screen displays icons that are used to control features of the mattress.

9. The patient support apparatus of claim 1, wherein the first state comprises the light being continuously illuminated green.

10. The patient support apparatus of claim 9, wherein the second state comprises at least one of an illuminated amber state and an illuminated red state.

11. The patient support apparatus of claim 1, wherein at least one of the first state and the second state comprises flashing the light.

12. The patient support apparatus of claim 1, wherein the light comprises a lens and at least one light producing element.

13. The patient support apparatus of claim 12, wherein the at least one light producing element includes a plurality of light producing elements.

14. The patient support apparatus of claim 13, wherein the plurality of light producing elements includes a first light emitting diode (LED) that is operable to emit green light and a second LED that is operable to emit red light or yellow light.

15. The patient support apparatus of claim 12, wherein the lens is frosted.

16. The patient support apparatus of claim 12, wherein the lens is textured.

17. The patient support apparatus of claim 12, wherein the light further comprises a lightpipe through which light from the light producing element passes before reaching the lens.

18. The patient support apparatus of claim 17, wherein the lightpipe is frosted.

19. The patient support apparatus of claim 17, wherein the lightpipe is textured.

20. The patient support apparatus of claim 1, wherein the light is in a third state when the patient support apparatus is in need of service.

21. A patient support apparatus comprising

a bed having a head end and a foot end,

control circuitry carried by the bed, the control circuitry receiving information about at least two conditions of the patient support apparatus, and

a light coupled to the bed frame adjacent the foot end and coupled to the control circuitry, wherein the light has a first state in which the light is illuminated green when no alert conditions are detected by the control circuitry based on the information and wherein the light has a second state in which the light is illuminated a color other than green when an alert condition is detected by the control circuitry based on the information, the first light indicating the alert condition in response to at least one of patient motion and a bed setting.

22. The patient support apparatus of claim 21, wherein the alert condition corresponds to a patient'"'"'s amount of motion exceeding a threshold.

23. The patient support apparatus of claim 21, wherein the alert condition corresponds to a patient attempting to exit the patient support apparatus.

24. The patient support apparatus of claim 21, further comprising a foot board coupled to the bed frame and the light is carried by the foot board.

25. The patient support apparatus of claim 24, further comprising a control panel carried by the foot board above the light.

26. A patient support apparatus comprising

a bed frame having a head end and a foot end, the bed frame including a mattress support deck,

a plurality of sensors to sense conditions of the patient support apparatus, the plurality of sensors including a first sensor that senses a first condition of the patient support apparatus and a second sensor that senses a second condition of the patient support apparatus,

control circuitry carried by the bed frame, the control circuitry receiving information from the plurality of sensors about conditions of the patient support apparatus, and

a light coupled to the bed frame adjacent the foot end and coupled to the control circuitry, the light being in a first state when the information from the plurality of sensors is indicative that the patient support apparatus is operating normally and the light being in a second state when the control circuitry detects an alert condition as determined by the information from at least one sensor of the plurality of sensors, wherein the first state includes the light being illuminated green and wherein the second state includes the light being illuminated a color other than green.

27. The patient support apparatus of claim 26, wherein the first sensor comprises a pressure sensor to sense pressure associated with a first zone of a mattress and the second sensor comprises a second pressure sensor to sense pressure associated with a second zone of the mattress.

28. The patient support apparatus of claim 26, wherein the light comprises a lens and a plurality of light producing elements each of which shines light through the lens when in a respective on state.
