A new device producing ambulatory intermittent pneumatic compression suitable for the treatment of lower limb oedema:...

The ideal conservative treatment for lower limb oedema would be one that provided intermittent compression whilst allowing the patient to remain mobile. In this article we describe the development of a pneumatic ambulatory compression device that utilizes the patient's weight applied, during walking, to air cells under the foot to provide compression to the ankle and calf. In volunteer studies this device typically produced a cycle of interface pressure changes from 20 to 45-50 mmHg on the lower calf and 20 to 35-40 mmHg on the upper calf.
