Abstract

A patient handling device includes a frame for supporting a patient, a controller, and two alert lights which are activated when a controller detects an alert situation, such as, but not limited to, a patient exiting from the patient handling device. The controller is in communication with the alert lights and operable to monitor an integrated bed exit system. The alert lights are positioned adjacent the foot end corners of the frame and are viewable by a user positioned anywhere within a 270 degree section of a circle defined at the center of the patient handling device. The alert lights include one or more Light Emitting Diodes (LEDs).

Claims

1. A bed comprising:

a frame adapted to support a mattress and a patient;

a load cell adapted to generate a load cell signal indicating a weight applied to the frame;

a bed exit system adapted to issue an alert when the bed exit system is in an armed state, the bed exit system issuing the alert based at least in part on the load cell signal;

a footboard having a control panel comprising a plurality of membrane-style pushbuttons;

a controller coupled to the bed exit system and to the control panel, the controller adapted to switch the bed exit system between the armed state and a disarmed state based at least in part upon a user input at the control panel; and

a first alert light positioned adjacent a first corner of a foot end of the frame and a second alert light positioned adjacent a second corner of the foot end of the frame, the first and second alert lights adapted to be activated in a first manner when the bed exit system issues the alert.

2. The bed of claim 1 further comprising a display integrated into the footboard, the display adapted to indicate the alert.

3. The bed of claim 1 wherein the bed exit system periodically acquires the load cell signal and, based on the acquired load cell signal, generates current load data.

4. The bed of claim 3 wherein the bed exit system issues the alert if a predetermined variation exists between the current load data and known desired load data.

5. The bed of claim 4 wherein the known desired load data is established based on the load cell signal at the time the bed exit system enters the armed state.

6. The bed of claim 2 wherein the display is a back-lit liquid crystal-type display.

7. The bed of claim 2 wherein the display is a touch-screen display.

8. The bed of claim 1 wherein the bed exit system comprises a plurality of user selectable sensitivity levels.

9. The bed of claim 8 wherein the plurality of user selectable sensitivity levels includes a movement sensitivity level and an exit sensitivity level.

10. The bed of claim 1 wherein the first and second alert lights collectively emit light that is viewable by a user positioned anywhere within 270 degrees of a circle defined at the bed.

11. The bed of claim 1 wherein the first and second alert lights collectively emit light that is viewable by a user positioned anywhere other than at a head end of the bed.

12. The bed of claim 1 wherein the first alert light and the second alert light are coupled to the frame, and not to the footboard.

13. The bed of claim 1 further comprising:

a plurality of siderails coupled to the frame and movable between a raise position and a lowered position;

a plurality of wheels supporting the frame;

a lifting mechanism adapted to raise and lower the frame; and

a brake pedal adapted to selectively immobilize the plurality of wheels.

14. The bed of claim 13 wherein the first alert light and the second alert light are adapted to emit an amber color when the bed exit system issues the alert.

15. The bed of claim 13 wherein the first alert light and the second alert light are adapted to flash when the bed exit system issues the alert.

16. The bed of claim 1 wherein the first alert light and the second alert light are further adapted to automatically stop acting in the first manner when the bed exit system discontinues the alert.

17. The bed of claim 13 wherein the first and second alert lights each include Light Emitting Diodes (LEDs).

18. A bed comprising:

a frame adapted to support a mattress and a patient;

a plurality of siderails coupled to the frame, each of the siderails being movable between a raised position and a lowered position;

a plurality of wheels supporting the frame;

a lifting mechanism adapted to raise and lower the frame;

a brake pedal adapted to selectively immobilize the plurality of wheels;

a bed exit system adapted to issue an alert when the patient exits from the bed;

a footboard having a control panel, the control panel including a control to arm and to disarm the bed exit system;

a first alert light positioned adjacent a first corner of a foot end of the frame;

a second alert light positioned adjacent a second corner of the foot end of the frame; and

a controller adapted to activate both the first and second alert lights when the bed exit system detects the patient exiting from the bed.

19. The bed of claim 18 wherein the first and second alert lights each include Light Emitting Diodes (LEDs).

20. The bed of claim 19 wherein the first and second alert lights collectively emit light that is viewable by a user positioned anywhere within 270 degrees of a circle defined around the bed.

21. The bed of claim 19 wherein the first and second alert lights collectively emit light that is viewable by a user positioned anywhere other than at a head end of the bed.

22. The bed of claim 18 wherein the first and second alert lights flash when the bed exit system detects the patient exiting from the bed.

23. A bed comprising:

a frame adapted to support a mattress and a patient;

a plurality of siderails coupled to the frame and movable between a raised position and a lowered position;

a plurality of wheels supporting the frame;

a lifting mechanism adapted to raise and lower the frame;

a brake adapted to selectively immobilize the plurality of wheels;

a bed exit system adapted to issue an alert when the patient exits from the bed;

a footboard having a control panel, the control panel including a control to arm and disarm the bed exit system;

a first alert Light Emitting Diode (LED) positioned adjacent a first corner of a foot end of the frame and not on the footboard;

a second alert LED positioned adjacent a second corner of the foot end of the frame and not on the footboard, the first and second LEDs being viewable by a user anywhere within 270 degrees of a circle defined around the bed; and

a controller adapted to illuminate the first and second LEDs when the bed exit system detects the patient exiting from the bed.

24. The bed of claim 23 wherein the first and second LEDs are adapted to emit an amber color when the patient exits from the bed.

25. The bed of claim 24 wherein the controller flashes the first and second LEDs when the patient exits from the bed.

26. The bed of claim 24 wherein the control panel includes a lift control for controlling the lifting mechanism.

27. The bed of claim 26 further including a siderail control panel having a plurality of patient movement controls adapted to move the bed, and wherein the control panel on the footboard further includes a plurality of lockout controls adapted to lock out the patient movement controls on the siderail control panel.
