Abstract

A patient support apparatus, such as a bed, cot, recliner, operating table, stretcher, or the like, includes a control panel with multiple controls for controlling functions of the patient support apparatus. A control system disables at least a first control and changes an illumination state of a backlight when the patient support apparatus is in a particular state. In some embodiments, the particular state is the arming of an exit detection system and/or the deactivation of a brake on the patient support apparatus. The particular state may also or alternatively be tied to a particular mode of the patient support apparatus, such as a diagnostic mode, a maintenance mode, and/or a normal mode. The control system may also never illuminate a first icon on the patient support apparatus if it was initially configured in a particular manner, such as being intended for sale in a particular geographic market.

First claim

What is claimed is:

1. A patient support apparatus comprising:
a frame;
a plurality of wheels;
a support surface supported by the frame and adapted to support a patient thereon;
an actuator assembly for moving the support surface to a plurality of different configurations;
an exit detection system that, when armed, is adapted to detect when the patient has exited the support surface,
a control panel including a first control for controlling a first function of the patient support apparatus and a second control for arming the exit detection system;
a first backlight for backlighting the first control and a second backlight for backlighting the second control; and
a control system adapted to disable the first control when the exit detection system is armed and to change an illumination state of the first backlight when the exit detection system is armed.

2. The patient support apparatus of claim 1 wherein the first control moves the support surface to one of a Trendelenburg configuration, a stand-assist configuration, and a flat configuration.

3. The patient support apparatus of claim 1 further including a third control on the control panel for controlling a third function of the patient support apparatus, and a third backlight for backlighting the third control, wherein the control system enables the third control and does not change an illumination state of the third backlight when the exit detection system is armed.

4. The patient support apparatus of claim 3 further including a battery for powering the actuator assembly, and the control system is further adapted to disable the first control when a charge level of the battery falls below a threshold.

5. The patient support apparatus of claim 3 further including a brake changeable between a braked state and an unbraked state, and wherein the first control moves the support surface to a stand-assist configuration in which the support surface is oriented to support the patient while the patient is nearly standing.

6. The patient support apparatus of claim 5 wherein the control system is further adapted to disable the first control when the brake is in the unbraked state and to change the illumination state of the first backlight when the brake is in the unbraked state.

7. The patient support apparatus of claim 1 further comprising:
a brake changeable between a braked state and an unbraked state;
a third control on the control panel adapted to control a third function of the patient support apparatus;
a third backlight for backlighting the third control; and
wherein the control system is further adapted to disable the third control when the brake is in the unbraked state and to change an illumination state of the third backlight when the brake is in the unbraked state.

8. The patient support apparatus of claim 7 wherein the control system enables the second control and does not change an illumination state of the second backlight when the brake is in the unbraked state.

9. The patient support apparatus of claim 8 wherein the third control moves the support surface to a stand-assist configuration in which the support surface is oriented to support the patient while the patient is nearly standing.

10. The patient support apparatus of claim 8 wherein the patient support apparatus is a recliner having a seat, a backrest, and a leg rest.

11. The patient support apparatus of claim 10 wherein the control system is further adapted to disable the third control when the exit detection system is armed.

12. The patient support apparatus of claim 11 wherein the third control moves the support surface to a stand-assist configuration in which the support surface is oriented to support the patient while the patient is nearly standing.

13. The patient support apparatus of claim 1 further comprising:
a plurality of actuators included with the actuator assembly;
a first icon and a second icon included within the control panel; and
wherein the control system is further adapted to switch the patient support apparatus from a first mode to a second mode, wherein the first icon is associated with a third function of the patient support apparatus and the second icon is associated with a fourth function of the patient support apparatus when the patient support apparatus is in the first mode, and wherein the first icon is associated with a fifth function of the patient support apparatus and the second icon is associated with a sixth function of the patient support apparatus when the patient support apparatus is in the second mode.

14. The patient support apparatus of claim 13 wherein the third function activates the plurality of actuators to move the support surface to a first configuration and the fourth function activates the plurality of actuators to move the support surface to a second configuration.

15. The patient support apparatus of claim 14 wherein the fifth function activates a first individual one of the plurality of actuators only, and the sixth function activates a second individual one of the plurality of actuators only.

16. The patient support apparatus of claim 13 wherein the third function indicates one of the different configurations of the support surface and the fourth function indicates diagnostic information regarding the patient support apparatus.

17. The patient support apparatus of claim 13 wherein the third function indicates one of the different configurations of the support surface and the fourth function indicates a code.

18. The patient support apparatus of claim 17 wherein the first icon includes a plurality of markers that are selectively illuminated to indicate the configuration of the support surface and that are selectively illuminated to indicate the code.

19. The patient support apparatus of claim 13 wherein the control panel further includes a third icon and a third backlight for backlighting the third icon, wherein the control system is further adapted to activate the third backlight when the patient support apparatus is in the first mode and to deactivate the third backlight when the patient support apparatus is in the second mode.
