Abstract

Claims (52)

1. A system for transporting a bed comprising a bed frame, the system comprising:

a drive system, wherein the drive system is configured to couple to the bed frame and to provide a powered movement of the bed frame;

a first control arm and a second control arm, wherein the first and second control arms are coupled to the bed frame, and wherein the first and second control arms are spaced apart to allow a user to move between the first and second control arms;

a first control handle coupled to the first control arm; and

a first switch on the first control handle, wherein the first switch is configured to control a function of the drive system, and wherein the first control handle is substantially vertical.

2. The system of claim 1 wherein the first control arm is configured to provide a manual movement of the bed in a left direction, a right direction, a forward direction, and a reverse direction.

3. The system of claim 1 wherein the drive system is configured to provide powered movement in a forward direction and a reverse direction.

4. The system of claim 1 wherein the drive system comprises a drive motor and a drive wheel.

5. The system of claim 4 wherein the first switch controls the speed of the drive motor.

6. The system of claim 1 wherein the first switch raises and lowers the drive system.

7. The system of claim 1 wherein the first control arm is substantially vertical.

8. The system of claim 1 further comprising:

a second control handle coupled to the second control arm.

9. The system of claim 8 wherein:

the second control handle comprises a second switch;

the first switch is configured to control the speed of the drive system; and

the second switch is configured to control the application of power to the drive system.

10. The system of claim 9 wherein the second control handle is substantially vertical and the first control handle comprises a third switch and the third switch is configured to raise and lower the drive system.

11. The system of claim 1 further comprising a directional switch configured to control the direction of the powered movement of the bed.

12. The system of claim 1 further comprising caster wheels configured to couple to the frame.

13. The system of claim 1 further comprising a lockout switch on the first control arm, wherein the lockout switch is located distal from the first control handle.

14. A patient transport system comprising:

a bed frame comprising a first end, a second end, and a pair of longitudinal sides extending between the first end and the second end;

a powered drive system coupled to the bed frame;

a first substantially vertical control arm coupled to the bed frame proximal to the first end;

a second substantially vertical control arm coupled to the bed frame proximal to the first end, wherein the first and second substantially vertical control arms are spaced apart;

a first control handle coupled to the first substantially vertical control arm;

a second control handle coupled to the second substantially vertical control arm;

a first switch on the first substantially vertical control arm, where the first switch is configured to control the application of power to the powered drive system; and

a second switch on the second substantially vertical control arm, where the second switch is configured to control the speed of the powered drive system, and wherein the first control handle and the second control handle are substantially vertical.

15. The patient transport system of claim 14 , further comprising:

a second switch on the first or second control handle, wherein the second switch is configured to control the application of power to the powered drive system.

16. The patient transport system of claim 14 , further comprising a third switch on the first or second control handle, wherein the first switch or the second switch is configured to control the speed of the powered drive system.

17. The patient transport system of claim 14 , further comprising a lockout switch on either the first or second substantially vertical control arm.

18. The patient transport system of claim 14 , further comprising a third switch on either the first or second control handle, wherein the third switch is configured to raise and lower the powered drive system.

19. A method of transporting a patient support surface, the method comprising:

providing a patient support surface;

providing a frame to support the patient support surface;

providing a drive system coupled to the frame;

providing a first substantially vertical control arm and a second substantially vertical control arm coupled to the frame;

providing a first vertical control handle coupled to the first substantially vertical control arm;

providing a second vertical control handle coupled to the second substantially vertical control arm;

providing a first switch on either the first or second vertical control handle;

engaging the drive system with a floor beneath the frame;

applying power to the drive system by operating the first switch; and

activating the drive system to transport the frame.

20. The method of claim 19 , further comprising:

exerting a force on the first vertical control handle or the second vertical control handle to steer the frame.

21. The method of claim 20 , further comprising:

regulating a speed at which the patient transport surface is transported by manipulating the first switch.

22. The method of claim 21 , further comprising:

providing a second switch on the first substantially vertical control arm or on the second substantially vertical control arm, wherein the second switch is configured to control the application of power to the drive system.
