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 said support structure;
a user interface comprising at least two handles coupled to said support structure, each one of said at least two handles respectively moveable between a stowed position and a non-stowed position;
a user input device coupled to said user interface; and
a controller coupled to said user input device, said controller being configured to electronically coordinate movement of said at least two handles to said stowed position upon actuation of said user input device.

2. The patient transport apparatus of claim 1 , wherein said controller is further configured to coordinate movement of said at least two handles to said non-stowed position upon actuation of said user input device.

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

4. The patient transport apparatus of claim 1 , wherein said user input device comprises one or more of a button, a knob, a sliding switch, a touch sensor and a toggle switch.

5. The patient transport apparatus of claim 1 , wherein said patient transport apparatus further comprises a brake assembly coupled to said support structure and electronically coupled to said controller, said brake assembly moveable between a braked position and an unbraked position, said brake assembly being configured to generate an electronic braking signal that is sent to the controller, and wherein said controller is configured to electronically coordinate movement of said at least two handles to said stowed position upon receipt of said electronic braking signal.

6. The patient transport apparatus of claim 5 , wherein said brake assembly comprises:
a foot pedal;
a brake actuator assembly coupled to said foot pedal and said support wheels; and
a brake sensor coupled to one of said foot pedal and said brake actuator assembly and to said controller, said brake sensor being configured to sense a change in position of said foot pedal or said brake actuator assembly and send said electronic braking signal to said controller.

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

8. The patient transport apparatus of claim 6 , wherein said electronic braking signal is further defined as a first electronic braking signal and said brake sensor is configured to generate and send said first electronic braking signal to said controller when said brake assembly is moved to said braked position and is also configured to generate and send a second electronic braking signal to said controller when said brake assembly is moved to said unbraked position.

9. The patient transport apparatus of claim 8 , wherein said controller is configured to electronically coordinate movement of said at least two handles to said stowed position upon receipt of said first electronic braking signal.

10. The patient transport apparatus of claim 9 , wherein said controller is configured to electronically coordinate movement of said at least two handles to said non-stowed position upon receipt of said second electronic braking signal.

11. The patient transport apparatus of claim 5 , wherein said electronic braking signal is further defined as a first electronic braking signal, and wherein said brake assembly further comprises a brake selector configured to generate said first electronic braking signal and a second electronic braking signal,
wherein said controller is configured to electronically coordinate movement of said at least two handles to said stowed position upon receipt of said first electronic braking signal, and
wherein said controller is configured to electronically coordinate movement of said at least two handles to said non-stowed position upon receipt of said second electronic braking signal.

12. The patient transport apparatus of claim 5 , wherein said controller is further configured to delay coordinated movement of said at least two handles to said stowed position for a predetermined amount of time after receipt of said electronic braking signal.

13. A patient transport apparatus comprising:
a support structure;
a plurality of support wheels coupled to said support structure; and
a user interface comprising at least two handles each respectively moveable between a stowed position and a non-stowed position,
a mechanical linkage operatively coupling said at least two handles in a coordinated manner such that movement of one of said at least two handles from said stowed position to said non-stowed position causes movement of each additional one of said at least two handles from said stowed position to said non-stowed position and such that movement of said one of said at least two handles from said non-stowed position to said stowed position causes movement of each of said additional one of said at least two handles from said non-stowed position to said stowed position.
