System and method for reporting status of a bed
View Patent ↗A method and system of reporting the status of a bed ( 12 ) whose occupant is at risk of an undesired event, includes indicating that the occupant is at risk of the undesired event and operating a lamp module ( 42 ) to signify a satisfactory status or an unsatisfactory status of the bed.
1. A method of reporting the status of a bed for an occupant at risk of falls, comprising:
determining if a Patient Position Monitoring (PPM) system is armed;
determining if a safeguard is in effect; and
operating a lamp module to signify a satisfactory status or an unsatisfactory status of the bed in response to the determining steps as set forth below:

2. The method of claim 1 wherein the safeguard is in effect only if all of one or more input conditions are satisfied.
3. The method of claim 2 wherein the input conditions to be satisfied include 1) a brake being set, 2) a height adjustable portion of the bed being at a lowest elevation, and 3) at least two laterally spaced apart siderails near the head end of the occupant being deployed.
4. The method of claim 1 wherein the safeguard is in effect if any one of one or more input conditions is satisfied.
5. The method of claim 4 wherein the input conditions to be satisfied include 1) a brake being set, 2) a height adjustable portion of the bed being at a lowest elevation, and 3) at least two laterally spaced apart siderails near the head end of the occupant being deployed.
6. The method of claim 1 including refraining from operating the lamp module if the PPM system is disarmed.
7. The method of claim 1 wherein the satisfactory status and the unsatisfactory status are distinguished from each other by a property of light emitted by the lamp module.
8. The method of claim 7 wherein the property of light is at least one of color and steadiness.
9. The method of claim 7 wherein the lamp module emits steady green light to signify the satisfactory status, the lamp module intermittently emits amber light to signify the unsatisfactory status and the lamp module emits substantially no visible light to signify that the PPM system is disarmed.
10. The method of claim 1 including a first lamp module dedicated to the satisfactory status, a second lamp module dedicated to the unsatisfactory status and wherein the satisfactory status is indicated by operating the first lamp module and the unsatisfactory status is indicated by operating the second lamp module.
11. The method of claim 10 wherein the satisfactory status and the unsatisfactory status are further distinguished from each other by a property of light emitted by the operated lamp module.
12. The method of claim 11 wherein the property of light is at least one of color and steadiness.
13. The method of claim 11 wherein the lamp module signifying the satisfactory status emits steady green light when operated and the lamp module signifying the unsatisfactory status intermittently emits amber light when operated.
14. The method of claim 1 wherein the lamp module is secured to the bed.
15. The method of claim 1 including:
determining if an auxiliary condition is acceptable or unacceptable; and
operating the lamp module to signify a satisfactory status or an unsatisfactory status of the bed in response to the determining steps as set forth below:

16. The method of claim 1 , wherein operating the lamp module includes directing light emitted from the lamp module at least partially toward a floor.
17. The method of claim 16 wherein the light is directed predominantly toward the floor.
18. The method of claim 15 wherein the lamp module is positioned and oriented so that light emitted from the module is directed at least partially toward a floor.
19. The method of claim 18 wherein the light is directed predominantly toward the floor.
20. A status reporting system for reporting whether or not an occupant of a bed is satisfactorily protected, comprising:
a Patient Position Monitoring (PPM) system having an armed state and a disarmed state;
at least one lamp module;
means responsive to the state of the PPM system and to a safeguard being in effect or not in effect for conditionally governing operation of the lamp module, the means producing a message to operate the lamp module in a first manner to signify a satisfactory status of the bed or a second manner to signify an unsatisfactory status of the bed as set forth below:

21. The system of claim 20 wherein the safeguard is in effect only if all of one or more input conditions are satisfied.
22. The system of claim 21 wherein the input conditions to be satisfied include 1) a brake being set, 2) a height adjustable portion of the bed being at a lowest elevation, and 3) at least two laterally spaced apart siderails near the head end of the occupant being deployed.
23. The system of claim 20 wherein the safeguard is in effect if any one of one or more input conditions is satisfied.
24. The system of claim 23 wherein the input conditions to be satisfied include 1) a brake being set, 2) a height adjustable portion of the bed being at a lowest elevation, and 3) at least two laterally spaced apart siderails near the head end of the occupant being deployed.
25. The system of claim 20 wherein the first manner is emission of visible light of a first color and the second manner is emission of visible light of a second color.
26. The system of claim 25 wherein one of the first and second manners of emission includes intermittent emission.
27. The system of claim 20 wherein the means also produces a message to operate the lamp module in a third manner if the PPM is in the disarmed state.
28. The system of claim 27 wherein the first manner is emission of visible light of a first color, the second manner is emission of visible light of a second color and the third manner is non-emission of visible light.
29. The system of claim 28 wherein one of the first and second manners of emission includes intermittent emission.
30. The system of claim 20 wherein the at least one lamp module includes multiple light emitters.
31. The status reporting system of claim 20 comprising:
determining if an auxiliary condition is acceptable or unacceptable; and
operating the lamp module in a first manner to signify a satisfactory status of the bed or a second manner to signify an unsatisfactory status of the bed in response to the state of the PPM system and to the safeguard being in effect or not in effect and to a status of an auxiliary condition as set forth below:
