Abstract

A patient handling device includes a deck for supporting a patient support surface, a controller, and a user interface. The user interface is actuatable by a user to record a state of a plurality of conditions of the patient handling device. The controller is in communication with the user interface and operable to monitor the plurality of conditions and to generate a first unified indication when all the conditions remain unchanged from their recorded state, and to generate a second indication when any of the conditions change from their recorded state.

Claims

1. A patient handling device comprising:

a plurality of components;

a plurality of sensors for generating sensor signals corresponding to said plurality of components;

a user-selectable control operable to initiate monitoring of said components of said patient handling device; and

a controller in communication with said sensors and said user-selectable control, said controller acquiring said sensor signals from said sensors in response to said user-selectable control and generating initial sensor data based on said acquired sensor signals to establish a desired state of said components, said controller periodically acquiring sensor signals from said sensors and generating current sensor data from said sensor signals based on said periodically acquired sensor signals from said sensors, and said controller comparing said current sensor data to said initial sensor data, generating a unified indication that said patient handling device is in a desired configuration when said current sensor data does not deviate from said initial sensor data, and generating another indication in response to a variation between said current sensor data and said initial sensor data.

2. A patient handling device as set forth in claim 1 further comprising a plurality of wheels supporting a frame and a brake for immobilizing at least one of said wheels.

3. A patient handling device as set forth in claim 2 wherein one of said sensors comprises a brake sensor for sensing activation of said brake.

4. A patient handling device as set forth in claim 1 further comprising a frame and a lifting mechanism for adjusting a height of said frame with respect to a surface.

5. A patient handling device as set forth in claim 4 wherein one of said sensors comprises a height sensor for sensing said height of said frame with respect to the surface.

6. A patient handling device as set forth in claim 4 wherein said frame includes an upper portion which is angularly adjustable with respect to a surface and further comprising an upper portion actuator operatively connected to said upper portion for actuating said upper portion to angularly adjust said upper portion.

7. A patient handling device as set forth in claim 6 wherein one of said sensors comprises an angular position sensor for sensing an angular position of said upper portion with respect to the surface.

8. A patient handling device as set forth in claim 1 further comprising at least one siderail moveable between an up position and a down position.

9. A patient handling device as set forth in claim 8 wherein one of said sensors comprises a siderail sensor for sensing the position of said at least one siderail.

10. A patient handling device as set forth in claim 1 wherein one of said sensors comprises a load cell for sensing a weight of a patient supported on said patient handling device.

11. A patient handling device as set forth in claim 1 wherein said user selectable control comprises a button for producing a control signal.

12. A patient handling device as set forth in claim 1 further comprising a bed exit system, and one of said sensors generating an arm/disarm signal from said bed exit system.

13. A patient handling device comprising:

a deck for supporting a patient support surface;

a controller; and

a user interface, said user interface being actuatable by a user to establish desired states for a plurality of patient handling device conditions of said patient handling device, said controller operable to monitor said plurality of patient handling device conditions, to generate a first unified indication when all said patient handling device conditions are in their desired states, and to generate a second indication when any of said patient handling device conditions are not in their desired states.

14. The patient handling device of claim 13 wherein said user interface is further configured to allow a user to select said plurality of patient handling device conditions.

15. The patient handling device of claim 13 wherein said second indication comprises a second unified indication when any of said patient handling device conditions are not in their desired states.

16. The patient handling device of claim 13 further comprising a plurality of sensors, said sensors detecting said states of said plurality of patient handling device conditions.

17. The patient handling device of claim 16 wherein said controller generates initial sensor data based on sensor signals generated by said sensors to establish a desired state of said conditions, said controller periodically acquiring sensor signals from said sensors and generating current sensor data from said sensor signals based on the periodically acquired sensor signals from said sensors, and said controller comparing said current sensor data to said initial sensor data, generating said unified indication that said conditions are in their desired states when said current sensor data does not deviate from said initial sensor data, and generating the second indication in response to a variation between said current sensor data and said initial sensor data.

18. The patient handling device of claim 17 wherein said sensors comprise at least two sensors selected from the group consisting of:

a siderail switch, a brake sensor, a load cell, a bed exit sensor, a lockout sensor, an angle sensor, and a height sensor.

19. The patient handling device of claim 13 wherein said patient handling device conditions include at least two conditions selected from the group consisting of:

a position of at least one siderail of said patient handling device;

an angular position of said deck;

a height of said deck;

the activation of a brake of said patient handling device; and

a state of a bed exit system of said patient handling device.

20. A patient handling device comprising:

a deck for supporting a patient support surface;

a controller; and

a user interface, said user interface being actuatable by a user to record a state of a plurality of conditions of said patient handling device, said controller in communication with said user interface and operable to monitor said plurality of conditions and to generate a first unified indication when all said conditions remain unchanged from their recorded state, and to generate a second indication when any of said conditions change from their recorded state.

21. The patient handling device of claim 20 wherein said second indication comprises a second unified indication when any of said conditions change from their recorded states.

22. The patient handling device of claim 20 wherein said conditions include at least two conditions selected from the group consisting of:

a position of at least one siderail of said patient handling device;

an angular position of said deck;

a height of said deck;

the activation of a brake of said patient handling device; and

a state of a bed exit system of said patient handling device.

23. The patient handling device of claim 20 wherein said user interface comprises a touch screen.
