ABSTRACT:
A therapeutic bed comprises a patient support platform 2 rotatably and pivotally secured within a main bed frame 3 through pivot mountings 4, the main bed frame being supported on a base frame 5 by two spaced-apart end uprights formed by a pair of hydraulic rams 6. Each ram is individually height adjustable and one of the pairs of rams is pivotally connected to the base frame by a crankshaft 7 which in turn is pivotally connected by a pivot 8 to the base frame. The other pair of rams is pivotally connected to the base frame by a shaft 9. An electric motor 10 drives a belt 15 to rotate or oscillate the patient support platform. The arc of oscillation of the patient support platform is controlled by a control unit which includes a potentiometer. Weighing means for the patient support platform is provided by a laod cell mounted between each of the pivot mountings and the main bed frame.
