The patient transport apparatus also includes an actuator assembly operatively coupling the first and second brake assemblies, with the actuator assembly comprising a first and second actuator respectively operatively coupled to the first and second brake assemblies. The actuator assembly further comprises a cable assembly interconnecting the first and second actuator that places the operatively coupled first and second brake assemblies in the braked state or the unbraked state.

According to one embodiment, a roll-in cot may include a support frame, a pair of front legs, a pair of back legs, and a cot actuation system. The pair of front legs may be slidingly coupled to the support frame. Each front leg includes at least one front wheel. The pair of back legs may be slidingly coupled to the support frame. Each back leg includes at least one back wheel. The cot actuation system includes a front actuator that moves the front legs and a back actuator that moves the back legs. The front actuator and the back actuator raises or lowers the support frame in tandem. The front actuator raises or lowers the front end of the support frame independently of the back actuator. The back actuator raises or lowers the back end of the support frame independently of the front actuator.

A powered ambulance cot and methods of raising and lowering the cot as well as loading and unloading the cot are disclosed. The cot includes a support frame and legs, each leg having a wheel. An actuator of an actuation system interconnects the frame and legs, and is configured to effect changes in elevation of the frame relative to the wheel of each of the legs. A control system controls activation of the actuation system, and detects both the actuator at a first location relative to the frame, where the first location is remote from a second location and which situates an end of the actuator that is remote from each wheel closer to the frame, and a presence of a signal requesting a change in elevation of said support frame to thereby cause the legs to move relative to the support frame.

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.

Patient transport apparatus with defined transport height comprises a support structure and a litter that are interconnected by a lift mechanism. The support structure comprises a base frame and a plurality of articulable support members or legs. The litter comprises a litter frame and a patient support surface with articulating back and leg sections. The lift mechanism may comprise one or more actuators configured to raise and lower the litter between a lowered position and one or more defined raised positions. The Patient transport apparatus may further comprise a controller coupled to one or more sensors and the lift mechanism. The controller may be configured to define a transport height for the litter based, at least in part, on a characteristic detected by the one or more sensors, and to manipulate the lift mechanism to adjust the litter to the defined transport height.

A patient transport apparatus comprises a support structure. The support structure comprises a base, a frame, and a patient support surface to support a patient. The patient transport apparatus also includes a first and a second caster assembly respectively coupled to the support structure to facilitate movement of the support structure along a floor surface, with the first caster assembly comprising a first brake assembly and the second caster assembly comprising a second brake assembly. The patient transport apparatus also includes an actuator assembly operatively coupling the first and second brake assemblies, with the actuator assembly comprising a first and second actuator respectively operatively coupled to the first and second brake assemblies. The actuator assembly further comprises a cable assembly interconnecting the first and second actuator that places the operatively coupled first and second brake assemblies in the braked state or the unbraked state.

Roll-in cots having lift assist mechanisms and lift assist mechanisms are disclosed. According to one embodiment, a lift assist mechanism includes a force application member having an actuation element, an actuation mechanism comprising a first grasp handle and a second grasp handle, and a force transmission assembly. The force transmission assembly includes a first keyway plate that is coupled to the first grasp handle, a second keyway plate that is coupled to the second grasp handle, and an actuation pin that extends through both the first keyway plate and the second keyway plate, where the actuation pin selectively applies a force to the actuation element of the force application member.

A patient transport apparatus comprises a support structure comprising base, a frame, and a patient support surface to support a patient. The apparatus also includes at least one caster assembly coupled to the support structure, with each one of the caster assemblies comprising a wheel, a wheel support coupled to the wheel, and a steer lock assembly movable relative to the wheel support. An actuator is operatively coupled to the steer lock assembly to move the steer lock assembly between a non-steer locked and steer locked state to permit or prevent the wheel support and coupled wheel from swiveling about a swivel axis. The caster assemblies can also include a brake assembly coupled to the wheel, with the actuator operatively coupled to the brake assembly to move the brake assembly between a braked and unbraked state.

A patient transport apparatus is provided for use with a retainer of a transport vehicle. The patient transport apparatus comprises a support structure comprising a patient support surface to support a patient. An engagement member is coupled to the support structure and arranged to engage the retainer when unloading the patient transport apparatus from the transport vehicle. A dampener is operable in a standby state or a resistance state such that the dampener provides increased resistance to movement of the patient transport apparatus in the resistance state as compared to the standby state. The resistance state of the dampener is activated by manually moving the patient transport apparatus in a first direction and the standby state is activated by manually moving the patient transport apparatus in a second direction, opposite the first direction.

Some embodiments of the disclosure are directed to latching interfaces of a vehicle. In some embodiments, the vehicle comprises a latch system including a plurality of latches configured to selectively interlock with a corresponding first plurality of latch receptacles of a respective payload. In some embodiments, the vehicle comprises a second plurality of latch receptacles disposed on exterior portions of the chassis of the vehicle. In some embodiments, the second plurality of latch receptacles correspond to the first plurality of latch receptacles. In some embodiments, a spatial arrangement of the second plurality of latch receptacles on the exterior portions of the chassis of the vehicle corresponds to a spatial arrangement of the first plurality of latch receptacles on exterior portions of the respective payload. In some embodiments, the second plurality of latch receptacles of the vehicle are configured to interlock with a latching interface of an external system.
