Abstract: A therapeutic bed includes a castor support framework and a Trendelenburg support frame including curved arms which are mounted on guide rollers of the castor frame. The Trendelenburg support frame carries guide rollers on which rings at opposite ends of the bed run. A patient support platform is mounted on the rings. A patient supine support including a mattress and leg supports are mounted on the patient support platform. Side rails are engagable and lockable to the platform. A patient prone support includes a head support, an adjustable abdomen support and support pad sections which are each split longitudinally to define adjustable support parts which are hingedly mounted to the corresponding opposite side rails, engaged and locked in position. The therapeutic bed provides for prone positioning of a patient by rotation of the rings on the rollers through 180.degree.. The bed may also be used for kinetic therapy and/or Trendelenburg motion when a patient is in the supine and/or prone position.

Abstract: A therapeutic hospital bed (1) comprises a patient support platform (2) rotatably and pivotally secured within a main bed frame (3). The main bed frame (3) is supported on a base frame (5). An end board on the patient support platform (2) has an arcuate track (14) engaged by a drive belt (15) which is connected to a drive motor for oscillating the patient support platform (2) relative to the main bed frame (3). Opposite ends of the drive belt (15) are connected to disengagement arms (18, 25) which are pivotally interconnected to form a scissors mechanism. The arms (18, 25) are operable to tension or release the belt (15) to engage or disengage drive to the patient support platform (2). A spring (27) extends between the arms (18, 25) to bias the arms (18, 25) into a belt tensioning position. To disengage the drive for turning the patient support platform (2) manually, the arms (18, 25) are movable against spring bias to a disengaged position.
