Abstract: A portable limb-mounted device for enhancing blood and/or lymph flow in a limb and/or for preventing stasis related disorders, the device comprising an energy generating device, an actuator, one or more compressing elements for generating squeezing forces on the limb of a user, a sensor located adjacent to the body of the user and coupled to a transceiver device, and a transceiver device coupled to the sensor to receive signals generated by the sensor, to transfer the signals received from the sensor device to a computing device. The device further comprises a computerized control system including a microcontroller and a memory device to store activity related information for subsequent downloads to an external computer-based monitoring device.

Abstract: The present invention provides a device for enhancing circulation by intermittently tightening and relaxing a closure encircling a limb. The device comprises a continuously operating motor, at least one rotating element and a mechanism driven by the motor for intermittently rotating the rotating element in a first direction to tighten said closure and in a second opposite direction to relax said closure, thereby applying a cyclic pressure on the limb.
