Abstract
A compression appliance includes a textile-based wrap, an electronic assembly, and wiring comprising a single wire looped through the length of the wrap. The wiring comprises shape changing materials that are used to apply controllable intermittent sequential compression or constriction pressure to a body portion of a person when the compression appliance is wrapped around the body portion. The appliance can incorporate a pre-tensioning element that applies a known initial tension to the shape changing material prior to activation of a compression cycle. The wire can be then actuated according to a compression protocol to sequentially contract and release the wire. The proposed wiring and component configuration will need access to lower power and a reduced volume of hardware as compared to conventional compression appliances.
