Abstract
Abstract A patient turning apparatus, for operation by a patient, in which a two-sectioned air mattress is placed on a patient''s bed having a width generally conforming to the width of the bed and a length terminating at the patient''s shoulders and calves. Each section of the air mattress is coupled through a different solenoid operated valve to a source of air pressure. A switch box disposed above the patient''s head, having coded buttons, operates the solenoids and allows the patient to inflate either side, effecting a turn either to the left or right, with a third control for exhausting both sections of the air mattress when desired.
