A retractor assembly for engaging a sheet on which a patient is disposed includes a transverse member and a pair of tethers coupled to the transverse member and extending from the transverse member for coupling to a winding assembly. A pair of sheet clamps are mounted to the transverse member, which are spaced apart along the longitudinal axis of the transverse member in a fixed spaced relationship for engaging a sheet at two points spaced along the longitudinal axis. The transverse member maintains the sheet clamps in their fixed spaced relationship whereby the sheet clamps resist inward migration toward each other when being used to handle a patient on a sheet.

Patient transfer device

A patient transfer device includes a base assembly movable in forward and lateral directions. A power train is mounted within the base assembly, and is connected to a clamping and strap assembly. A power and switching system is in electrical communication with the power train. A retractor bar carries one or more clamping devices that are releasably attachable to a sheet. The clamping devices include a clamp handle pivotally connected to a clamp base and a clamp arm eccentrically pivotally connected to the clamp handle. The clamping and strap assembly is supported on the base assembly by a vertical adjustment assembly that includes a positioning mechanism for releasably locking the clamping and strap assembly at one of a plurality of vertical positions. An attendant can stand on the base assembly to act as a counterbalance to a patient's weight.

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.

Wheeled carriage having a powered auxiliary wheel, auxiliary wheel overtravel, and an auxiliary wheel drive and control system

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.

Wheeled carriage having auxiliary wheel spaced from center of gravity of wheeled base and cam apparatus controlling deployment of auxiliary wheel and deployable side rails for the wheeled carriage

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.

Deployable siderails for a wheeled carriage

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.

Balanced fowler design

A bed has movable upper body and knee support sections, and first and second coupling arrangements which each couple a respective drive arrangement to one of the upper body and knee support sections to effect movement thereof between inclined and horizontal positions. Each coupling arrangement includes two telescoping tubes and a locking mechanism for releasably holding the tubes against relative movement, the locking mechanisms of both coupling arrangements being released in response to manual operation of a release handle. Each locking mechanism includes a transverse cylindrical locking element rotatably supported on a first of the tubes for movement between a locking position in which a portion thereof engages a semicylindrical recess in the second tube, and a release position in which the tubes are free to move relative to each other with a portion of the second tube which extends lengthwise thereof sliding within a transverse recess in the locking element.

Emergency drop fowler and gatch

A delivery bed includes two spaced foot support assemblies which project outwardly from one end thereof. Each foot support assembly includes a first horizontally extending member having a top surface with transversely extending grooves and having a bottom surface, and a second member having two spaced, transversely extending rods which respectively slidably engage the top surface and bottom surface of the first member, the second member having therein a foot-shaped recess. A pad can be removably supported on the two foot support assemblies without any need for additional support structure for the pad intermediate the foot support assemblies. The pad is held in place by two fastening straps which extend downwardly between the foot support assemblies and are each releasably coupled to a respective one of the foot support assemblies. Alternatively, the pad can be held in place by brackets on the pad which releasably engage brackets provided on the foot support assemblies near the outer ends thereof.

Breakaway foot section for delivery bed

A mattress for use on a hospital stretcher has an upwardly facing support surface which can support a patient. The top surface of the mattress has a plurality of small, parallel ribs which extend transversely of the mattress, and which resist sliding movement of the patient lengthwise of the mattress while simultaneously facilitating sliding movement of the patient transversely of the mattress. The mattress has bevels extending along opposite sides of the support surface, the support surface being provided on a sheetlike material which extends from a lower edge of one bevel to a lower edge of the other bevel without intervening seams extending lengthwise of the mattress. The sheetlike material is preferably a laminate which includes a rip-resistant scrim layer made of a closely woven spun polyester material and two vinyl layers disposed on respective sides of the scrim layer, the ribs being provided in one of the vinyl layers on a side thereof remote from the scrim layer.
