ABSTRACT:
Therapeutic apparatus for treatment of patients requiring stimulation of blood circulation has a main, castered, L-shaped frame beneath a secondary, L-shaped, mattress-supporting frame, presenting uprights that are pivotally interconnected at their upper ends for continuous swinging movement of the secondary frame alternately to upper and lower inclined, dwell positions about a transverse, horizontal axis disposed at a height essentially the same as that of the head of the patient lying on the mattress. A cam and timer-controlled motor on the main frame, remote from the uprights, has cranks on its outer shaft that are pivotally connected at preselected positions on links, in turn swingable on the secondary frame, for varying the extent of swinging of the secondary frame in both directions.
