An inflation garment for the treatment of DVT is operated by a portable, battery powered air pump and controller detachably mounted on the inflation garment. The controller is formed with hook-fastening devices on the bottom surface of the controller that is detachably engagable with the material on the outer surface of the inflation garment. To mount the controller, the inflation garment is folded to expose the air inlet and outlet ports on the inflation garment to facilitate the operative attachment of the controller ports, then the inflation garment is unfolded and pressed against the bottom surface of the controller to engage the hook fasteners with the material of the inflation garment. A supplemental support is provided to wrap at least partially around the inflation garment to enhance the support of the inflation garment on the patient's limb without slipping.
