a push handle unit coupled to the head end of the upper frame for movement with the upper frame, and
a control system including an input unit and a controller coupled to the input unit and the lift system, the controller configured to receive a caregiver parameter from the input unit, to determine caregiver height based on the caregiver parameter from the input unit, and to move the upper frame upwardly or downwardly relative to the lower frame to a push position corresponding to the determined caregiver height so that the push handle unit is positioned for ergonomic use by the caregiver in response to receipt of a run signal associated with movement of the patient support apparatus along a floor.
2. The patient support apparatus of claim 1 , wherein the input unit includes a sensor configured to detect distance from the sensor to the top of a caregiver and to send the distance to the controller.
3. The patient support apparatus of claim 1 , wherein the input unit includes a RFID reader coupled to the controller, the RFID reader configured to detect a caregiver identifier from a caregiver RFID tag and to send the caregiver identifier to the controller.
4. The patient support apparatus of claim 3 , wherein the controller is configured to determine caregiver height based on the caregiver identifier.
5. The patient support apparatus of claim 1 , wherein the input unit includes a graphical user interface coupled to the controller, the graphical user interface configured to receive a caregiver identifier from a caregiver.
6. The patient support apparatus of claim 5 , wherein the controller is configured to determine caregiver height based on the caregiver identifier.
7. The patient support apparatus of claim 1 , wherein the push handle unit includes a grip and a user input coupled to the grip.
8. The patient support apparatus of claim 7 , wherein the lower frame includes a brake system coupled to the head-end casters and the foot-end casters, the brake system moveable between an engaged position, arranged to block rotation of the head-end casters and the foot end casters, and a disengaged position, arranged to allow rotation of the head-end casters and the foot-end casters, and the controller is configured to determine caregiver height, to move the upper frame to the push position, and to move the brake system from the engaged position to the disengaged position in response to receiving a request from the user input.
9. The patient support apparatus of claim 1 , wherein the lower frame includes a brake system coupled to the head-end casters and the foot-end casters, the brake system moveable between an engaged position, arranged to block rotation of the head-end casters and the foot end casters, and a disengaged position, arranged to allow rotation of the head-end casters and the foot-end casters, and the controller is coupled to the brake system, and the controller is configured to move the brake system from the engaged position to the disengaged position after the controller moves the upper frame to the push position.
10. The patient support apparatus of claim 1 , wherein the controller is configured to receive the run signal from a run button.
11. The patient support apparatus of claim 7 , wherein the controller is configured to receive the run signal from a force applied to the grip.
12. A patient support apparatus comprising
a lower frame including head-end casters and foot-end casters,
an upper frame including a head end and a foot end, the upper frame supported above the lower frame,
a push handle unit including a grip and a handle motion unit coupled to the grip and to the upper frame to move the grip upwardly and downwardly relative to the upper frame and
a controller coupled to the push handle unit, wherein the controller is configured to determine caregiver height and to move the push handle unit upwardly or downwardly relative to the upper frame to a push position corresponding to the determined caregiver height so that the push handle unit is positioned for ergonomic use by the caregiver in response to receipt of a run signal associated with movement of the patient support apparatus along a floor.
13. The patient support apparatus of claim 12 , further comprising a sensor coupled to the controller, the sensor configured to detect caregiver height and to send the caregiver height to the controller.
14. The patient support apparatus of claim 12 , further comprising a RFID reader coupled to the controller, the RFID reader configured to detect a caregiver identifier from a caregiver RFID tag and to send the caregiver identifier to the controller.
15. The patient support apparatus of claim 14 , wherein the controller is configured to determine caregiver height based on the caregiver identifier.
16. The patient support apparatus of claim 12 , further comprising a graphical user interface coupled to the controller, the graphical user interface configured to receive a caregiver identifier from a caregiver.
17. The patient support apparatus of claim 16 , wherein the controller is configured to determine caregiver height based on the caregiver identifier.
18. The patient support apparatus of claim 12 , wherein the push handle unit includes a user input coupled to the grip and to the motion unit.
19. The patient support apparatus of claim 18 , wherein the motion unit is configured to move the grip relative to the upper frame in response to a caregiver input received by the user input.
20. The patient support apparatus of claim 12 , wherein the handle motion unit is coupled to grip and to the upper frame to move the grip about a pivot axis relative to the upper frame.
21. The patient support apparatus of claim 20 , wherein the pivot axis is arranged to extend along the head end of the upper frame.
22. The patient support apparatus of claim 12 , wherein the controller is configured to receive the run signal from a run button.
23. The patient support apparatus of claim 18 , wherein the controller is configured to receive the run signal from a force applied to the grip.
