A wheeled carriage for supporting a patient has a wheeled base having frame members supporting a plurality of caster wheel assemblies and a braking system. A moveable brake lock assembly, a brake lock actuator, and a swivel lock receiver are operatively connected to one of the caster wheel assemblies to define a locking caster wheel assembly. The brake lock assembly comprises an actuating member, a swivel lock member, and a brake member that are interconnected as a unit for simultaneous movement. The brake lock actuator is operable to selectively move the brake lock assembly into an engaged position via engagement with the actuating member such that the swivel lock member engages the swivel lock receiver and the brake member contacts a wheel of the locking caster wheel assembly thereby preventing rotation and swiveling of the wheel.

A patient support apparatus includes a base, a litter frame, and an elevation mechanism interconnecting the base to the litter frame and being configured to effect changes in elevation of the litter frame relative to the base. The elevation mechanism includes a pair of hydraulic actuators, each actuator covered by a telescoping shroud. The telescoping shroud is connected to the base and to the litter frame by a number of biased catches. The litter frame includes a pair of laterally spaced and longitudinally extending support rails and a plurality of laterally extending support rails interconnecting the longitudinally extending support rails so that the litter frame has a rectangular configuration. The litter frame includes a thigh section configured to be raised and lowered by use of one of a manually pumped hydraulic actuator or a gas-spring assisted lever actuator.

Patient support apparatus

A patient support apparatus having a base, a litter frame, an elevation mechanism interconnecting the base to the litter frame and being configured to effect changes in elevation of the litter frame relative to the base. The litter frame includes a pair of laterally spaced and longitudinally extending support rails and a plurality of laterally extending support rails interconnecting the longitudinally extending support rails so that the litter frame has a rectangular configuration. Selected ones of the laterally extending support rails are mounted to the elevation mechanism. On the aforesaid litter frame there is mounted various modules, namely, (1) a patient support deck, (2) a set of lateral edge siderails, (3) a holder for bottled gas, (4) an attendant work surface, oriented beneath the head section when the head section is in a horizontal position, (5) a seat, thigh and foot section assembly, and (6) a head section having manipulatable controls thereon supportingly secured to the litter frame separately from the seat, thigh and foot section assembly.

A wheeled carriage for supporting a patient in a substantially horizontal position includes a patient support having head and foot ends and a wheeled base supported by castered wheels. Auxiliary wheels are suspendably mounted on a wheel support structure with the axis of the auxiliary wheels spaced from a midpoint of the wheeled base. A control apparatus controls the wheel support structure to move the auxiliary wheels between a first deployed position whereat castered wheels at one end of the carriage are elevated from a floor surface, and a second stored position with the auxiliary wheels out of engagement with the floor surface. The wheeled carriage includes a drive motor for powering the auxiliary wheels. A drive member applies force to a load cell on the wheeled carriage. The load cell outputs a drive signal to drive the auxiliary wheels. An auxiliary wheel drive and control system accelerates or decelerates the carriage by comparing the drive signal with a threshold value that changes dependent on the velocity of the carriage.

The wheel brake includes a crank arm mounted on the patient support. An elongate first link is pivotally connected at one end to a first pivot pin provided on the distal end of the aforesaid crank arm. An elongate second link is pivotally secured to the patient support for movement about a second axis of rotation and is pivotally secured on one side of the second axis of rotation to the first link by a second pivot pin. A wheel engaging brake member is swingably suspended from the bed frame and above an outer periphery of a wheel rotatably and swivelably supported on the bed frame and for movement into and out of engagement with the aforesaid outer periphery. An elastically yieldable resilient member and an elongate third link are interconnected between the wheel engaging brake and the second link.

Caster brake mechanism

A wheeled carriage for supporting a patient in a substantially horizontal position, which wheeled carriage has thereon a patient support having head and foot regions and a pair of lateral side regions and a wheeled base supported at least by three floor surface engaging and castered wheels spaced from one another at locations defining corners of a theoretical polygon. An auxiliary wheel and a support structure therefor are suspendedly mounting the auxiliary wheel to the wheeled base. The auxiliary wheel is oriented inside a boundary of the theoretical polygon and includes an axle about which the wheel rotates. A control structure includes a first manually manipulatable member at at least one of the pair of lateral side regions and a second manually manipulatable member at at least one of the head end and the foot end so that an attendant can operate a selected one of the manually manipulatable members to effect a movement of the auxiliary wheel and the support structure therefor. In the alternative, the control structure can selectively activate the brakes for the wheeled carriage. A unitary pedal is provided for controlling the height of the patient support.

Brake for castered wheels

A wheeled carriage for supporting a patient in a substantially horizontal position, the wheeled carriage has thereon a patient support having head and foot ends and a wheeled base supported by castered wheels. An auxiliary wheel and a wheel support structure therefor suspendedly mount the auxiliary wheel at its axis to the wheeled base at a distance L in a horizontal direction from the center of gravity of the wheeled carriage along the length of the wheeled base when the auxiliary wheel is engaged with the floor surface. A moment M,is defined by the distance L multiplied by a force F,, the force F,being defined by the mass of the carriage or carriage and patient at the center of gravity. The moment M,is greater at all times than a moment M,to prevent teetering of the wheeled carriage, where moment M,is defined by multiplying the height H by a force F,. The force F,is the force required to move the wheeled carriage. The height H is defined by the vertical distance between the axis of the auxiliary wheel and the relative height of the gripping location where the force F,is applied.

A side rail assembly for a wheeled carriage includes side rail posts secured by a support structure including bushings having inner flat sides that expand outwardly to adjust for variations in the tolerance of the side rail posts and snugly secure the side rail posts to the support structure. Such variations can be caused by a finished surface applied to the entire outer circumference of the side rail posts and the support structure to improve the appearance thereof. The support structure enables curved side rail posts to rotate about their axis at lower ends thereof.

Unitary pedal control of brake and fifth wheel deployment via side and end articulation with additional unitary pedal control of height of patient support

A patient support stretcher which includes a base and a main frame portion coupled to the base through at least one pair of crossbars forming an X-shaped configuration. The crossbars are pivotally connected to one another and are pivotally connected to the base and the main frame portion. A back support or a fowler section is hinged to the main frame portion and a strut interconnects the back support to the main frame to provide the requisite balanced leverage for effecting the simultaneous lift of the main frame and the fowler section.
