Abstract

Claims (26)

1. A patient support apparatus, comprising:

a patient support surface including a rotation device, and

a controller operable to control the rotation device, the controller including a processor and a non-transitory memory device, the memory device including instructions that, when executed by the processor, cause the processor to operate the rotation device to perform a rotation preview sequence prior to the processor being operated to initiate a rotation sequence in which the patient support surface is moved to a desired angle of rotation by the rotation device and held in the desired angle of rotation for a dwell time,

wherein, during the rotation preview sequence, the controller causes the rotation device to move the patient support surface to a first evaluation position for a first predetermined period of time that is less than the dwell time, wherein the first predetermined period of time enables the caregiver to assess a patient on the patient support surface at the first evaluation position,

wherein, during the rotation preview sequence, the rotation device moves the patient support surface to a flat position after the first predetermined period of time, and

wherein, after the rotation preview sequence, the caregiver is enabled to activate the rotation sequence to move the patient support surface to the desired angle of rotation and held at the desired angle of rotation for the dwell time that is greater than the first predetermined period of time of the rotation preview sequence.

2. The patient support apparatus of claim 1 , wherein, during the first predetermined period of time, the caregiver is enabled to cancel the rotation preview sequence so that the controller returns the patient support surface to the flat position before an expiration of the first predetermined period of time.

3. The patient support apparatus of claim 1 , wherein:

the rotation device includes a left rotation bladder and a right rotation bladder, and

the first evaluation position includes at least one of a left rotation position, wherein the left rotation bladder is inflated to a capacity greater than the right rotation bladder, and a right rotation position, wherein the right rotation bladder is inflated to a capacity greater than the left rotation bladder.

4. The patient support apparatus of claim 3 , wherein, in the flat position, the right rotation bladder and the left rotation bladder are inflated to substantially the same capacity.

5. The patient support apparatus of claim 1 , wherein the first evaluation position has an angle of rotation relative to a longitudinal axis of the patient support surface that is within a range of 1 degree to 40 degrees.

6. The patient support apparatus of claim 1 , wherein the first predetermined period of time is within a range of 0 seconds to 30 seconds.

7. The patient support apparatus of claim 1 , wherein, during the rotation preview sequence, the rotation device moves the patient support surface to a second evaluation position for a second predetermined period of time, wherein the second predetermined period of time begins at the expiration of the first predetermined period of time.

8. The patient support apparatus of claim 7 , wherein the second predetermined period of time enables the caregiver to assess the patient on the patient support surface at the second evaluation position.

9. The patient support apparatus of claim 7 , wherein the second evaluation position has angle of rotation that is substantially zero.

10. The patient support apparatus of claim 7 , wherein the second predetermined period of time is within a range of 0 seconds and 30 seconds.

11. The patient support apparatus of claim 7 , wherein, during the rotation preview sequence, the rotation device moves the patient support surface to a third evaluation position for a third predetermined period of time, wherein the third predetermined period of time begins at an expiration of the second predetermined period of time.

12. The patient support apparatus of claim 11 , wherein the third predetermined period of time enables the caregiver to assess a position of a patient on the patient support surface at the third evaluation position.

13. The patient support apparatus of claim 12 , wherein the rotation device moves the patient support surface to the flat position after the third predetermined period of time.

14. The patient support apparatus of claim 11 , wherein, during the third predetermined period of time, the caregiver is enabled to cancel the rotation preview sequence so that the controller returns the patient support surface to the flat position before an expiration of the third predetermined period of time.

15. The patient support apparatus of claim 11 , wherein the third evaluation position has an angle of rotation relative to a longitudinal axis of the patient support surface that is within a range of 1 degree to 40 degrees.

16. The patient support apparatus of claim 11 , wherein the third predetermined period of time is within a range of 0 seconds and 30 seconds.

17. The patient support apparatus of claim 1 , wherein a display includes buttons for the caregiver to enter initial rotation parameters prior to the start of the rotation preview sequence.

18. The patient support apparatus of claim 17 , wherein the initial rotation parameters include the desired angle of rotation.

19. The patient support apparatus of claim 1 , wherein during a training preview the control system causes intermittent movement of the rotation device to the desired angle of rotation over a plurality of periods of time.
