Abstract

A patient transport apparatus transports a patient over a floor surface and includes a support structure and a plurality of support wheels coupled to the support structure. The patient transport apparatus also includes a user interface including at least two handles coupled to the support structure, with each of the handles movable between a stowed position and non-stowed position. The patient transport apparatus also includes a user input device coupled to the user interface, and a controller coupled to the user interface. The controller is configured to electronically coordinate the movement of the handles to the stowed position upon actuation of the user input device.

First claim

What is claimed is:

1. A patient transport apparatus comprising:
a support structure;
a plurality of support wheels coupled to the support structure;
a user interface comprising at least two handles coupled to the support structure, each one of the at least two handles respectively moveable between a stowed position and a non-stowed position;
a user input device including a touch sensor arranged for user engagement; and
a controller coupled to the user input device, the controller being configured to electronically coordinate movement of the at least two handles between the stowed position and the non-stowed position in response to changes in user engagement with the touch sensor of the user input device.

2. The patient transport apparatus of claim 1 , wherein the controller is further configured to coordinate movement of the at least two handles to the non-stowed position in response to detecting user engagement with the touch sensor of the user input device.

3. The patient transport apparatus of claim 1 , wherein the touch sensor of the user input device is coupled to the user interface.

4. The patient transport apparatus of claim 1 , wherein the user input device is configured to transmit a first input signal and a second input signal to the controller, the controller being configured to coordinate movement of the at least two handles to the stowed position upon receiving the first input signal and to coordinate movement of the at least two handles to the non-stowed position upon receiving the second input signal.

5. The patient transport apparatus of claim 1 , wherein the user input device further includes one or more of a button, a knob, a sliding switch, and a toggle switch.

6. The patient transport apparatus of claim 1 , wherein the patient transport apparatus further comprises a brake assembly coupled to the support structure and electronically coupled to the controller, the brake assembly being moveable between a braked position and an unbraked position, the brake assembly being configured to generate an electronic braking signal; and
wherein the controller is coupled to the brake assembly and is configured to electronically coordinate movement of the at least two handles to the stowed position in response to receiving the electronic braking signal from the brake assembly.

7. The patient transport apparatus of claim 6 , wherein the controller is configured to electronically coordinate movement of the at least two handles to one of the stowed position and the non-stowed position upon receipt of the electronic braking signal.

8. The patient transport apparatus of claim 6 , wherein the controller is further configured to delay coordinated movement of the at least two handles to the stowed position for a predetermined amount of time after receipt of the electronic braking signal.

9. The patient transport apparatus of claim 6 , wherein the brake assembly includes:
a brake actuator assembly arranged to operate at least one of the support wheels between the braked position and the unbraked position; and
a brake input device coupled to the brake actuator assembly and arranged for user engagement to move the brake actuator assembly between the braked position and the unbraked position.

10. The patient transport apparatus of claim 9 , wherein the brake input device comprises a foot pedal.

11. The patient transport apparatus of claim 9 , wherein the brake assembly further includes a brake sensor to generate the electronic braking signal, with the brake sensor being arranged to determine operation between the braked position and the unbraked position.

12. The patient transport apparatus of claim 11 , wherein the electronic braking signal is further defined as a first electronic braking signal and the brake sensor is configured to generate the first electronic braking signal when the brake assembly is moved to the braked position; and
wherein the brake sensor is further configured to generate a second electronic braking signal when the brake assembly is moved to the unbraked position.

13. The patient transport apparatus of claim 12 , wherein the controller is configured to electronically coordinate movement of the at least two handles to the stowed position upon receipt of the first electronic braking signal.

14. The patient transport apparatus of claim 12 , wherein the controller is configured to electronically coordinate movement of the at least two handles to the non-stowed position upon receipt of the second electronic braking signal.

15. The patient transport apparatus of claim 1 , further comprising an actuator device coupled to the user interface and to the controller to drive movement of the at least two handles between the stowed position and the non-stowed position.

16. The patient transport apparatus of claim 15 , wherein the actuator device includes at least two servo motors respectively coupled to the at least two handles.

17. The patient transport apparatus of claim 15 , further comprising a mechanical linkage operatively coupling the at least two handles in a coordinated manner such that movement of one of the at least two handles from the stowed position to the non-stowed position causes movement of each additional one of the at least two handles from the stowed position to the non-stowed position and such that movement of the one of the at least two handles from the non-stowed position to the stowed position causes movement of each of the additional one of the at least two handles from the non-stowed position to the stowed position.
