Abstract

A mobile patient bed may be used for moving a patient between at least two locations during a medical procedure. The mobile patient bed may comprise an interface configured to selectively couple the mobile patient bed to at least one medical system and at least one processor configured to receive a medical system command via the interface and process the medical system command when the mobile patient bed is coupled to the at least one medical system, receive and process a user command when the mobile patient bed is not coupled to the at least one medical system, and refrain from processing the user command when the mobile patient bed is coupled to the at least one medical system. The mobile patient bed may also comprise a seat and a plurality of motors configured to independently position the seat along a plurality of axes.

Claims

1. A mobile patient bed for moving a patient between at least two locations during a medical procedure, the mobile patient bed comprising:

a communication device configured to selectively couple the mobile patient bed to at least one medical system;

at least one processor configured to;

receive a medical system command via the communication device and process the medical system command when the mobile patient bed is coupled to the at least one medical system;

receive and process a user command when the mobile patient bed is not coupled to the at least one medical system; and

refrain from processing the user command when the mobile patient bed is coupled to the at least one medical system;

a seat; and

a plurality of motors configured to position the seat along a first axis that is longitudinal with respect to the bed, a second axis substantially perpendicular to the first axis, and a third axis substantially perpendicular to the first and second axes, wherein the positioning of the seat along each axis is independent of the positioning of each other axis, respectively, and wherein the positioning of the seat is performed in response to the processed medical system command or the processed user command.

2. The mobile patient bed of claim 1, further comprising a headrest configured to pivot about a fourth axis substantially parallel to the first axis and to move along the fourth axis, a fifth axis substantially perpendicular to the fourth axis, and a sixth axis substantially perpendicular to the fourth and fifth axes, wherein the positioning of the headrest along each axis is independent of the positioning of each other axis, respectively.

3. The mobile patient bed of claim 1, wherein the communication device comprises a Bluetooth transceiver or other wireless transceiver.

4. The mobile patient bed of claim 1, further comprising at least one user control configured to input the user command to the at least one processor.

5. The mobile patient bed of claim 4, wherein the at least one user control comprises a pendant, a handle, a foot pedal, or a combination thereof.

6. The mobile patient bed of claim 1, further comprising a joystick coupled to the at least one processor and configured to input a user command to the at least one medical system via the communication device.

7. The mobile patient bed of claim 1, wherein the mobile patient bed is coupled to the medical system in at least one of the locations and not coupled to the medical system in at least another one of the locations.

8. The mobile patient bed of claim 1, wherein the plurality of motors are configured to position the seat in a Trendelenburg position.

9. The mobile patient bed of claim 1, wherein the medical system is a laser eye surgery system.

10. The mobile patient bed of claim 1, further comprising a plurality of casters, wherein at least one of the casters is lockable to allow the mobile patient bed to pivot about a pivoting axis.

11. The mobile patient bed of claim 10, further comprising a brake configured to lock at least one of the casters from rotation.

12. The mobile patient bed of claim 10, wherein at least two of the casters are directionally lockable.

13. The mobile patient bed of claim 1, further comprising at least one of a foot rest motor, a Trendelenburg motor, and a head rest motor.

14. The mobile patient bed of claim 1, further comprising a seat sensor configured to detect a person on the seat.

15. The system of claim 14, wherein the medical system is configured to determine a location of the at least one mobile patient bed via a signal received from the communication device of the at least one mobile patient bed.

16. The system of claim 14, wherein the medical system is configured to assign a separate identity to each at least one mobile patient bed.

17. The system of claim 14, wherein the communication device is configured to send status information to the medical system.

18. The system of claim 14, wherein the medical system is configured to control the at least one processor via a command sent to the communication device.

19. A system comprising:

at least one mobile patient bed of claim 1; and

the medical system.

20. The system of claim 19, wherein:

the medical system comprises a plurality of receivers configured to receive the signal; and

determining the location of the at least one mobile patient bed comprises performing triangulation based on the signal received at each of the plurality of receivers.

21. A method of performing a medical procedure, the method comprising:

moving a mobile patient bed between at least two locations during a medical procedure;

in at least one of the at least two locations, coupling, with a communication device of the mobile patient bed, the mobile patient bed to at least one medical system;

receiving, via at least one processor, a medical system command via the communication device and processing, with the at least one processor, the medical system command when the mobile patient bed is coupled to the at least one medical system;

refraining, with the at least one processor, from processing a user command when the mobile patient bed is coupled to the at least one medical system;

in at least another one of the at least two locations, decoupling the mobile patient bed from the at least one medical system;

receiving and processing, with the at least one processor, a user command when the mobile patient bed is not coupled to the at least one medical system; and

in at least one of the at least two locations, positioning, with a plurality of motors of the mobile patient bed, a seat of the mobile patient bed along a first axis that is longitudinal with respect to the bed, a second axis substantially perpendicular to the first axis, and a third axis substantially perpendicular to the first and second axes, wherein the positioning of the seat along each axis is independent of the positioning of each other axis, respectively, and wherein the positioning of the seat is performed in response to the processed medical system command or the processed user command.

22. The method of claim 21, further comprising, in at least one of the at least two locations, positioning a headrest configured to pivot about a fourth axis substantially parallel to the first axis and to move along the fourth axis, a fifth axis substantially perpendicular to the fourth axis, and a sixth axis substantially perpendicular to the fourth and fifth axes, wherein the positioning of the headrest along each axis is independent of the positioning of each other axis, respectively.

23. The method of claim 21, wherein positioning the seat comprises positioning the seat into a Trendelenburg position.

24. The method of claim 21, wherein the medical procedure is a laser eye surgery.

25. The method of claim 21, further comprising, in at least one of the at least two locations, locking at least one caster of the mobile patient bed and pivoting the mobile patient bed about a pivoting axis of the at least one locked caster.

26. The method of claim 21, further comprising determining, with the medical system, a location of the at least one mobile patient bed via a signal received from the communication device of the at least one mobile patient bed when the mobile patient bed is coupled to the at least one medical system.

27. The method of claim 26, wherein determining the location of the at least one mobile patient bed comprises performing triangulation based on the signal being received at each of a plurality of receivers of the medical system.

28. The method of claim 21, further comprising assigning, with the medical system, a separate identity to each at least one mobile patient bed when the mobile patient bed is coupled to the at least one medical system.

29. The method of claim 21, further comprising detecting, with a seat sensor, a person on the seat.
