A patient support apparatus includes a pedal assembly for selecting between a first state and a second state different from the first state, and comprising first and second pedals. The first and second pedals are configured to pivot together in a first rotational direction relative to a respective pivot axis to transition from the first state to the second state, and the first and second pedals are configured to pivot together in a second rotational direction opposite the first rotational direction to transition from the second state to the first state. At least a distal portion of the first pedal is configured to pivot independently from the second pedal in the first rotational direction when in the first state, and at least a distal portion of the second pedal is configured to pivot independently from the first pedal in the second rotational direction when in the second state.

The present invention relates to a removable electric propulsion system (1) for a rolling object, propulsion system (1) comprising a chassis (2) provided with at least one wheel (3) driven by an electric machine, at least one non-driven wheel (4) and at least one means for coupling electric propulsion system (1) to the rolling object. The coupling means comprises at least one means providing combined and simultaneous gripping and lifting of at least one wheel of the rolling object, and the combined and simultaneous gripping and lifting means comprises a frame (23), at least one arm (24) extendable in a longitudinal direction (x) and connected to frame (23), at least one tilt element (22) and at least one push device (20), one among tilt element (22) and push device (20) being connected to said extendable arm (24) and the other to chassis (2), said push device (20) being capable of driving at least one wheel of the rolling object along said longitudinal direction (x) into said at least one tilt element (22), said tilt element (22) being capable of tilting about an axis of substantially transverse direction (21).

The invention also relates to a coupling method and to a device for coupling a propulsion system to the rolling object.

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.

A bed is provided. The bed may include a lift system which raises and lowers a support deck of the bed. The lift system may include multiple individually actuatable lift systems. The bed may include a powered bed mover system.

A patient litter basket spin control assembly for use on a patient litter basket is provided. The assembly comprises thruster unit for discharging an air stream and is mounted on the patient litter basket. At least one sensor is associated with the thruster unit for sensing rotational movement or spin of the patient litter basket, and a power source is provided for powering the thruster unit and the sensor. A clamp member mounts on the patient litter basket and releasably receives the thruster unit. The sensors modulate the force of the air stream from the thruster unit so that the air stream counters the rotational movement of the patient litter basket to stabilize the patient litter basket by preventing the spin.

A patient support apparatus includes a plurality of primary sensors adapted to measure different parameters used in the control of the patient support apparatus. One or more suites of secondary sensors are added to the patient support apparatus to provide data about the primary sensors. The secondary sensors may be used to detect errors in the primary sensors, to modify outputs from the primary sensors, and/or to provide usage and/or diagnostic data about the use of the patient support apparatus. The suite(s) of secondary sensors may measure parameters that affect the outputs of one or more of the primary sensors. In some embodiments, the suite(s) of secondary sensors include one or more dormant sensors that are not used on the patient support apparatus until a code modification is received from one or more external sources instructing the control system of the patient support apparatus to begin using the dormant sensor(s).

A patient transport apparatus transports a patient over a surface. The patient transport apparatus comprises a support structure comprising a base, a patient support surface, and a reference sensor arranged to sense inclination of the support structure. A drive system is coupled to the support structure and operable to propel the patient transport apparatus. A handle assembly is operable by a user to control operation of the drive system. The handle assembly comprises a handle movable relative to the base and a position sensor arranged to sense positioning of the handle. A controller is coupled to the reference sensor and the position sensor, and is adapted to control the drive system in response to signals received from the reference sensor and the position sensor.
