Abstract

A patient support apparatus, such as a hospital bed, includes an alert light assembly or an alert light module having separate zones that are individually illuminated to convey information regarding respective alert conditions. The zones each have indicia related to a particular condition of the patient support apparatus. The illuminated zones are each sufficiently large so as to be seen from afar, such as on the order of ten feet or more. Alternatively or additionally, a GUI of the patient support apparatus displays alert indicia as part of a screen saver. Further alternatively or additionally, the patient support apparatus illuminates an alert light in a manner indicating an optimal time for taking a patient'"'"'s vital signs.

Claims

1. A patient support apparatus for use in a room having a room surface, the patient support apparatus comprising

a frame including a base frame and an upper frame supported above the base frame and configured to support a patient, the upper frame having a head end, a foot end, and a pair of laterally spaced apart sides, the head end and foot end being spaced apart in a longitudinal dimension of the patient support apparatus, and

an alert light module coupled to the frame and having a plurality of light emitters, each light emitter being operable to project onto the room surface a lighted iconic image having a shape associated with a monitored condition of the patient support apparatus.

2. The patient support apparatus of claim 1, wherein the alert light module includes a housing having a wall that includes a plurality of shaped cutouts, each shaped cutout defining a shape of the iconic image, and each light emitter emits light through a respective one of the shaped cutouts to project the iconic image on the room surface.

3. The patient support apparatus of claim 2, wherein the housing has an interior region and the plurality of light emitters is situated in the interior region of the housing.

4. The patient support apparatus of claim 2, wherein the wall of the housing that includes the shaped cutouts comprises a bottom wall of the housing.

5. The patient support apparatus of claim 4, wherein the housing has a front wall extending upwardly from the bottom wall and openings are formed in the front wall.

6. The patient support apparatus of claim 2, wherein the upper frame has a lateral frame member at the foot end and the alert light module is coupled to the lateral frame member.

7. The patient support apparatus of claim 2, wherein the housing has a set of openings spaced from the shaped cutouts and further comprising lenses, each lens covering a respective one of the openings.

8. The patient support apparatus of claim 7, wherein each lens has a graphical image thereon, each graphical image having a shape that is substantially similar to a shape of a respective one of the shaped cutouts.

9. The patient support apparatus of claim 7, wherein the housing has a set of partition walls in an interior region of the housing, each partition wall being situated between a respective pair of the light emitters such that each light emitter emits light through a respective one of the lenses and a respective one of the cutouts.

10. The patient support apparatus of claim 2, wherein each of the shaped cutouts has associated therewith a pair of the light emitters, a first light emitter of the pair of light emitters emitting green light and a second light emitter of the pair of light emitters emitting at least one of amber light and red light.

11. The patient support apparatus of claim 1, wherein the alert light module is mounted to the upper frame.

12. The patient support apparatus of claim 11, wherein the upper frame has a frame member and the alert light module hangs downwardly from the frame member.

13. The patient support apparatus of claim 12, wherein the frame member comprises a laterally extending frame member situated adjacent the foot end.

14. The patient support apparatus of claim 1, wherein the room surface comprises a floor of the room.

15. The patient support apparatus of claim 1, wherein the alert light module is situated near the foot end.
