Reconfigurable transport apparatus
A transport apparatus includes a frame, a lift mechanism supporting the frame, and a litter deck for supporting a person. The litter deck is adapted to be reconfigured between a chair configuration and a cot configuration. The litter deck is also adapted to be removably mounted to the frame, with the litter deck being adapted to be supported by the frame while the litter deck is in its chair configuration and also while being reconfigured between its chair configuration and its cot configuration.
STRETCHER
A stretcher is provided that may include a patient support, a base, a connection member being pivotally connected to the patient support and pivotally connected to the base such that the patient support, the base, and the connection member can form a Z-shape with a first angle at the corner of the Z-shape between the patient support and the connection member and a second angle at the other corner of the Z between the base and the connection member, a first angle adjustment device for controlling the first angle, and a second angle adjustment device for controlling the second angle such that the first angle adjustment device and the second angle adjustment device can be operated independently of each other. A method of loading and unloading a stretcher from an ambulance is also provided.
Patient Support Apparatus With Powered Unloading Dynamic Weigh Adjustment
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.
Patient Support Apparatus With Hydraulic Oscillation Dampening
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.
POWERED AMBULANCE COT WITH AN AUTOMATED COT CONTROL SYSTEM
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.
LOADING PLATFORM ALIGNMENT SYSTEM AND LOADING/UNLOADING METHOD THEREOF
A method and an alignment system which auto-levels and/or auto-centers a loading platform (104) to load and unload a wheeled stretcher (106) to and from an emergency transport vehicle (100) are disclosed. A controller (114) of the alignment system receives a command to extend the loading platform from the emergency vehicle and extends the loading platform under power from the emergency transport vehicle. The controller recognizes an approaching wheeled stretcher, and aligns automatically the loading platform with a leading edge of the approaching wheeled stretcher to compensate automatically for any alignment issues between the loading platform and loading wheels (130) of the wheeled stretcher.
Methods and Systems for Automatically Articulating Cots
A power ambulance cot having a cot control system operably connected to a cot actuation system to control independent raising and lowering of front and back legs thereof, and which detects a presence of a signal requesting a change in elevation of a support frame thereof and causes the cot actuation system to raising or the lowering of the front and/or back legs automatically upon detecting a condition during loading/unloading a patient from an emergency vehicle or transporting the patient up or down an esculator and methods thereafter are disclosed.
Hydraulic circuit for a patient handling apparatus
A patient handling apparatus includes a patient support surface, a base, and a hydraulic circuit. The hydraulic circuit includes a pump, a fluid reservoir, and a hydraulic cylinder operable to selectively raise or lower the patient support surface or the base. The hydraulic circuit controls flow of fluid between the cylinder and the fluid reservoir to thereby control the movement of the base or patient support surface. In addition, the hydraulic circuit may include a manual bypass circuit configured to bypass the pump in response to a manual input, which allows manual extension or retraction of the cylinder, for example, when the pump is not operational. The hydraulic circuit may also include a pump bypass circuit configured to bypass the pump to allow fluid to discharge from the cap end to the fluid reservoir for faster evacuation of fluid from the cylinder, thereby increasing retraction speed of the rod.
COT FASTENING SYSTEM
A cot fastening system for fastening a cot to an emergency vehicle includes a frame configured for mounting to the floor of an emergency vehicle, which has a longitudinal axis and a cot loading direction along the longitudinal axis. A first restraint assembly is for coupling to a foot end cot attachment of a cot and is mounted to the frame. A second restraint assembly is for coupling to a head end cot attachment of the cot and is mounted to the frame. The frame includes a first section and a second section. The first section has a first width less than the spacing between head end wheels of the cot to allow the cot to straddle the frame. The second section extends from the first end of the first section along the longitudinal axis of the frame and diverges away from the longitudinal axis of the frame to a second width greater than the first width but less than the spacing between the head end wheels to form a guide for guiding the head end wheels of the cot when the head end cot attachment has passed the first restraint assembly and is at or near the second restraint assembly to thereby guide the head end cot attachment into alignment with the second restraint assembly.
A LOADING AND UNLOADING APPARATUS
A patient transport loading and unloading apparatus for an emergency vehicle includes at least one support configured for mounting at the access opening of the vehicle and a stationary mount. The support is deployable relative to the stationary mount between a stowed position (in which the support cannot support the patient transport apparatus) and a loading position. Further, the support is configured to remain stationary when the patient transport apparatus is loaded onto the support and while the patient transport apparatus is moved into the vehicle through the access opening.
