Sterilizable battery component

A bed having a base, a pedestal mounted on the base and a patient supporting member mounted on the pedestal. The pedestal is generally centrally oriented relative to the base and to the patient supporting member and includes a mechanism for effecting an elevating of the patient supporting member relative to the base. A stabilizing mechanism is provided for enabling the pedestal to accommodate differing elevations between the base and the patient supporting member and yet facilitate a maintaining of longitudinal axis congruency between the relatively movable components of the pedestal so that an orientation of the patient supporting member will remain relatively fixed with respect to the base independent of a height of the patient supporting member relative to the base. In addition, the stabilized patient supporting member of the bed has a fowler section wherein the lower region thereof is supported for movement toward the head end of the patient supporting member as the fowler section is elevated from a horizontally aligned position to other positions oriented at an obtuse angle with respect to the remainder portion of the patient supporting member.

Surgical table

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.
