In the spring of 1922, there was constructed at the medical supply depot, Coblenz, Germany, a movable frame with netting for the purpose of enclosing a bed. It was based on a description given by Dr. H. C. Michie of a similar device he had seen in a hospital in Vienna. It was in use at the Station Hospital in Coblenz until this place was given up, and then forwarded to the Walter Reed General Hospital. As will be seen from the illustration, it consisted of an iron frame large enough to fit around and over a hospital bed. It had plenty of head room, and was covered with a heavy netting. This device serves effectually to restrain a patient with purposeless delirium without the constant services of an attendant. With the closed frame in place, it is impossible for such a patient either to get out or to fall
