Abstract

A patient mobility system for early patient ambulation. The system includes a patient support apparatus having a patient support surface supported by a base adapted to rest upon a floor surface. A first actuator may move the patient support deck relative to the base. An ambulation device is removably coupled to the patient support apparatus and includes wheels, a barrier, and a second actuator. The second actuator may move the barrier to a height sufficient to prevent egress of the patient in a coupled configuration, and/or adjust a height of the barrier relative to the wheels in a decoupled configuration so as to provide a grip to support to the patient during ambulation away from the patient support apparatus. A controller may be operable to control at the first and/or second actuators.

Claims

1. A patient mobility system for early ambulation of a patient, said patient mobility system comprising:

a patient support apparatus comprising a base adapted to rest upon a floor surface, a patient support surface supported by said base, and a first actuator arranged to move said patient support deck relative to said base; and

an ambulation device removably coupled to said patient support apparatus to define a coupled configuration, said ambulation device configured to engage the floor surface and provide support to the patient during ambulation away from said patient support apparatus when said ambulation device and said patient support apparatus are decoupled defining a decoupled configuration, said ambulation device comprising a barrier, wheels coupled to said barrier, and second actuator arranged to move said barrier relative to said wheels to a height sufficient to at least partially extend above said patient support surface to prevent egress of the patient in said coupled configuration.

2. The patient mobility system of claim 1, further comprising a coupling feature on each of said patient support apparatus and said ambulation device, wherein said first and second actuators are operable to adjust a height of the coupling features relative to the floor surface to facilitate moving said patient mobility system between said coupled and decoupled configurations.

3. The patient mobility system of claim 1, further comprising a controller in communication with said first and second actuators, said controller configured to control said first and second actuators to facilitate moving said patient mobility system between said coupled and coupled configurations.

4. The patient mobility system of claim 3, further comprising sensors in communication with said controller and configured to provide positional information of said ambulation device relative to said patient support apparatus, wherein said controller is configured to control said first and second actuators based on the positional information to move said patient mobility system from said decoupled configuration to said coupled configuration.

5. The patient mobility system of claim 3, further comprising a user input device in communication with said controller, said user input device configured to receive an input from a user and said controller configured to operate at least one of said first and second actuators based on the input.

6. The patient mobility system of claim 1, wherein patient support apparatus is adapted to support said ambulation device off the floor surface in said coupled configuration.

7. The patient mobility system of claim 1, wherein said second actuator is configured to adjust a height of said barrier relative to said wheels in said decoupled configuration.

8. The patient mobility system of claim 1, wherein said ambulation device further comprises a plurality of articulating members, wherein said second actuator is coupled to said plurality of articulating members and operable to articulate at least one of said articulating members.

9. The patient mobility system of claim 1, wherein said barrier further comprises a handle to form a grip for providing support to the patient during ambulation away from said patient support apparatus.

10. A patient mobility system for early ambulation of a patient, said patient mobility system comprising:

a patient support apparatus comprising a base adapted to rest upon a floor surface, a patient support surface supported by said base, and a first actuator;

an ambulation device removably coupled to said patient support apparatus to define a coupled configuration, said ambulation device configured to engage the floor surface when said ambulation device and said patient support apparatus are decoupled defining a decoupled configuration, said ambulation device comprising a barrier, wheels coupled to said barrier, and second actuator; and

a controller in communication with said first and second actuators, said controller configured to control said first and second actuators to move said patient mobility system from said coupled configuration to said decoupled configurations, and to control said second actuator to adjust a height of said barrier relative to said wheels in said decoupled configuration so as to provide a grip to support to the patient during ambulation away from said patient support apparatus.

11. The patient mobility system of claim 10, further comprising sensors in communication with said controller and configured to provide positional information of said ambulation device relative to said patient support apparatus, wherein said controller is configured to control said first and second actuators based on the positional information to move said patient mobility system from said decoupled configuration to said coupled configuration.

12. The patient mobility system of claim 10, wherein said controller is configured to operate said second actuator to adjust a height of said barrier relative to said wheels in said decoupled configuration.

13. The patient mobility system of claim 10, further comprising a user input device in communication with said controller, said user input device configured to receive an input from a user and said controller configured to operate at least one of said first and second actuators based on the input.

14. The patient mobility system of claim 13, wherein said user input device is coupled to one of said patient support apparatus and said ambulation device.

15. The patient mobility system of claim 13, wherein said user input device is disposed on a handheld device.

16. The patient mobility system of claim 13, wherein said controller is further configured to operate said second actuator to adjust a height of said barrier between preset height positions as programmed by the user on said user input device.

17. A patient mobility system for early ambulation of a patient, said patient mobility system comprising:

a patient support apparatus comprising a base adapted to rest upon a floor surface, and a patient support surface supported by said base; and

an ambulation device removably coupled to said patient support apparatus to define a coupled configuration, said ambulation device configured to engage the floor surface and provide support to the patient during ambulation away from said patient support apparatus when said ambulation device and said patient support apparatus are decoupled defining a decoupled configuration, said ambulation device comprising wheels, a barrier, a plurality of articulating members coupled to said wheels and said barrier, and an actuator operable to articulate said articulating members to adjust a height of said barrier relative to said wheels.

18. The patient mobility system of claim 17, wherein the height of said barrier is sufficient to at least partially extend above said patient support surface in said coupled configuration.

19. The patient mobility system of claim 17, further comprising a controller in communication with said actuator, said controller configured to control said actuator to articulate said articulating members.

20. The patient mobility system of claim 17, wherein said actuator is a second actuator, said patient support apparatus further comprising a first actuator arranged to move the patient support deck relative to said base.
