Abstract

A patient support apparatus includes a deck, a plurality of side rails, a control panel, and a plurality of subsystems, such as a bed exit system that detects when a patient may exit from the support apparatus, or a lifting mechanism to raise and lower the deck. A controller is in communication with the control panel and is adapted to monitor conditions regarding the side rails and/or the other subsystems. At least one lamp is also provided on the patient support apparatus that is adapted to be illuminated in a first manner when a plurality of monitored conditions remain in a desired state, and in a second manner when at least one of the plurality of monitored conditions changes to an undesired state.

Claims

1. A patient support apparatus comprising:

a deck for supporting a patient;

a first sensor supported by said patient support apparatus, said first sensor adapted to generate a first sensor signal corresponding to a first particular condition of said patient support apparatus;

a second sensor supported by said patient support apparatus, said second sensor adapted to generate a second sensor signal corresponding to a second particular condition of said patient support apparatus, said second particular condition being different from said first particular condition;

a controller adapted to acquire information about the first and second particular conditions, said controller adapted to compare the first sensor signal to a first predetermined parameter and to compare the second sensor signal to a second predetermined parameter; and

a lamp in communication with said controller and positioned adjacent a foot end of the patient support apparatus, said lamp producing green light only when there is no substantial variation between both the first sensor signal and the first predetermined parameter and between the second sensor signal and the second predetermined parameter.

2. The apparatus of claim 1 further including:

a third sensor supported by said patient support apparatus, said third sensor adapted to generate a third sensor signal corresponding to a third particular condition of said patient support apparatus, said third particular condition being different from both said first particular condition and said second particular condition;

wherein said lamp produces green light only when there is no substantial variation between the first sensor signal and the first predetermined parameter and between the second sensor signal and the second predetermined parameter and between the third sensor signal and the third predetermined parameter.

3. The apparatus of claim 2 wherein said first particular condition is a positional status of a siderail on said patient support apparatus, and said second particular condition is a height of said deck.

4. The apparatus of claim 2 wherein said first particular condition is an activation state of a bed exit system on said patient support apparatus.

5. The apparatus of claim 2 wherein said controller is adapted to allow a caregiver to set said first and second predetermined parameters.

6. The apparatus of claim 2 further including an interface adapted to communicate with a remote station, said interface adapted to transmit information regarding a specific room location of the patient support apparatus within a facility.

7. The apparatus of claim 2 wherein said deck includes a Fowler section that is pivotable between a flat orientation and a raised orientation and said patient support includes an actuator for raising and lowering said Fowler section at variable speeds.

8. The apparatus of claim 2 wherein said patient support apparatus includes a plurality of control panels and said lamp is positioned away from all of said control panels at a location free of any adjacent indicia that would indicate a meaning of the green light of said lamp.

9. The apparatus of claim 1 further including a controller area network adapted to transport data to and from said controller.

10. The apparatus of claim 4 further including a controller area network adapted to transport data to and from said controller.

11. The apparatus of claim 1 wherein said first particular condition is a positional status of a siderail on said patient support apparatus, and said second particular condition is a height of said deck.

12. The apparatus of claim 1 wherein said first particular condition is an activation state of a bed exit system on said patient support apparatus.

13. The apparatus of claim 2 wherein said first particular condition is a positional status of a siderail on said patient support apparatus, said second particular condition is a height of said deck, and said third particular condition is an activation state of a bed exit system on said patient support apparatus.
