Leg saver. Chester Antos, student at Georgetown University medical school, photographed with the newly devised Emerson suction pressure apparatus which designers believe will prevent amputation in many cases. The mechanical "boot" is to be used in treatment of severe cases of peripheral vascular diseases. The device was developed by Dr. Louis A. Hermann of Cincinnati. By increasing and decreasing the air pressure alternatively, the "boot" tends to stimulate circulation through the leg. The pump boot is a gift to Georgetown University Hospital from an alumnus. 11/12/35
