The general surgeon and the physician are frequently confronted with a patient suffering from obstinate lymph stasis of an extremity. Relief of this refractory condition has come through the use of three rather simple devices: (1) a sleeve or stocking woven of a special nonelastic fabric in the length of which are incorporated two inflatable rubber tubes of about 1 in. caliber (see figure,A); (2) a specially constructed electrically operated timing device, permitting inflation of the rubber tubes for 15 seconds and a collapsing rest of those tubes for 45 seconds of every minute that the device is in operation; and (3) a small tank of compressed air or medical oxygen for inflation of the rubber tubes. The functioning of this therapeutic device is seen in the following case report. REPORT OF A CASE A 45-year-old woman had a radical mastectomy in July, 1948.
