Abstract: A patient transport apparatus transports a patient over a floor surface. The patient transport apparatus comprises a support structure and support wheels coupled to the support structure. An auxiliary wheel is coupled to the support structure to influence motion of the patient transport apparatus over the floor surface to assist users. An actuator is operatively coupled to the auxiliary wheel and operable to move the auxiliary wheel relative to the support structure from a retracted position to a deployed position. A user interface sensor is operatively connected to the actuator and configured to generate signals responsive to the user touching the user interface. A controller is operatively coupled to the user interface sensor and the actuator to operate the actuator in response to detection of signals.

Abstract: A patient transport apparatus transports a patient over a floor surface. The patient transport apparatus comprises a base and support wheels coupled to the base. An auxiliary wheel is coupled to the base to influence motion of the patient transport apparatus over the floor surface to assist users. A wheel drive system is operatively coupled to the auxiliary wheel to rotate the auxiliary wheel relative to the base at a rotational speed. A throttle assembly having a throttle operably coupled to the actuator. The throttle is movable in a first position, a second position, and intermediate positions between the first and second positions. The rotational speed of the auxiliary wheel changes in a non-linear manner with respect to movement of the throttle.

Abstract: A patient transport apparatus transports a patient over a floor surface. The patient transport apparatus includes a support structure and a drive wheel assembly having at least one drive wheel, a powered drive system coupled to the at least one drive wheel, and at least two user input devices. The apparatus also includes a controller coupled to the powered drive system and user input devices configured to determine which one of the user input devices is active and operable to cause the powered drive system to rotate the drive wheel and to maintain the other user input device as inactive, or passive.

Abstract: Systems for facilitating movement of a patient transport apparatus are provided and include user input control device that includes a mode switch selectable between a longitudinal transport mode and a multidirectional mode and a driving assist device actuatable between at least one engaged state and a non-engaged state. The mode switch generates signals based on the selected mode and the driving assist device generates engaged or non-engaged signals which are received by a controller. The controller is configured to generate an output signal sent to a lift actuator, swivel actuator, and/or a powered drive system to assist a user in propelling the apparatus in a desired manner.
