A system for loading a patient transport apparatus into a vehicle is described. The system includes a loading and unloading system including a track and a trolley supporting a receiver movable between locked and unlocked configurations. The system also includes a patient transport apparatus for attachment to the loading and unloading system including a base, a litter, and a lift mechanism to facilitate arranging the litter at different heights relative to the base with an actuator movable between fully-retracted and fully-extended configurations, a coupler for engaging the receiver to secure the patient transport apparatus, first and second sensors configured to output a first signal and second signal and a controller to determine a target lift configuration during unloading from the emergency based on first and second values and to drive the actuator to the target lift configuration to limit relative movement between the patient transport apparatus and the trolley.

A patient transport apparatus with a base, a litter comprising a support surface, and a lift mechanism to facilitate arranging the litter at different heights relative to the base between a plurality of lift configurations including a fully-retracted configuration and a fully-extended configuration. The lift mechanism includes an actuator including a cylinder, fluid reservoir, and a pump driven by a motor to direct hydraulic fluid from the fluid reservoir to the cylinder. A sensor outputs a signal indicative of a magnitude of pressure in the cylinder. A user interface with an input control is provided. A controller determines a target parameter for the motor and, in response to user engagement with the input control, drives the motor at the target parameter to effect movement of the litter relative to the base at a predetermined rate irrespective of a weight of a patient supported on the litter.

A patient support system with chest compression system and harness assembly with sensor system. The harness assembly secures shoulders and hips of the patient on a patient support surface during transport. A chest compression system is integrated into the harness assembly in a manner that provides chest compressions to the patient while the patient is secured on the patient support surface. The tension of the harness assembly is selectively adjusted and/or a fluid bladder may be selectively expanded. A controller is in communication with the chest compression system and controls operation of the chest compression system. The sensor system is integrated into the harness assembly and in communication with the controller. The chest compression system may be removable from the harness assembly via an adapter. The chest compression system may be integrated into the patient support apparatus to secure the patient to the patient support surface while providing chest compressions.

A patient transport apparatus comprising a support frame, a base, a bracket coupled to the support frame and comprising a channel being non-linear, a frame assembly coupled between the support frame and the base and comprising a slidable member disposed in the channel, the slidable member being moveable between a plurality of different positions in the channel to place the support frame in a plurality of different poses relative to the base. The patient transport apparatus also comprises a sensor configured to detect the slidable member in the channel and produce a reading, as well as a controller coupled to the sensor and configured to receive the reading from the sensor, determine the position of the slidable member in the channel based on the reading, and determine the pose of the support frame relative to the base based on the determined position of the slidable member.

An ambulance cot loading and unloading system for an emergency vehicle includes a base for mounting in the emergency vehicle and an arm mounted for linear movement along the base, wherein the arm configured to support a cot while the cot is being loaded into or unloaded from the emergency vehicle. The ambulance cot loading and unloading system further includes an indicator mounted relative to the arm and a control system, which is in communication with the indicator and configured to generate a status indication of the cot loading and unloading system at the indicator.

A patient support apparatus comprises a support structure comprising a base and a patient support surface to support a patient. An actuator system facilitates movement of the patient support surface relative to a floor surface. One or more sensors are responsive to changes in position of the patient support surface caused by the actuator system. A controller is operably coupled to the one or more sensors and the actuator system. The controller is configured to operate the actuator system to move the patient support surface and to monitor the movement of the patient support surface by sensing positions of the patient support surface over time. The controller is further configured to identify a frictional load event on the actuator system during movement in a present cycle and associate the frictional load event with a sensed position of the patient support surface in the present cycle.

In a mobile stretcher, in order to change the height position of a patient support mounted on a chassis, the chassis geometry is modifiable by a hydraulic drive system. The drive system includes a linear actuator, a pressure supply unit, and a receiving space for hydraulic fluid. A manually actuatable unlocking valve unit directly connects a lifting working chamber of the linear actuator to the receiving space. The valve unit has a control space delimited by a piston element movably guided relative to the housing of the valve unit and which communicates with a lifting attachment, which communicates with the working chamber. The piston element is operatively connected to a valve body interacting with a valve seat of a relief valve between the lifting attachment and a tank attachment communicating with the receiving space. A mechanical actuation input acts on the valve body, with a spring element interposed.

A first transport apparatus includes a deck for supporting a patient thereon and a lift mechanism supporting the deck. The deck is removable from the lift mechanism for use as a second transport apparatus or part of a second transport apparatus. The first transport apparatus further includes an electrically powered device at the first transport apparatus, and a user input device for wireless control of the electrically powered device, which is operable at or near the first transport apparatus and the second transport apparatus.
