Abstract

A one-piece slipper construction, into which an inflatable foot-pump bag or bladder is permanently integrated and wherein a thin reinforcement panel is fully contained and located within a flat-foldable wrap, for selective completion of the circumferential tie that is needed for assurance of stimulated foot-pump action. In the preferred embodiment, the wrap is so further devised as to provide a flexibly reinforced, non-stretch backing reference for a laterally extending portion of the inflatable bag, for active stimulation of the adjacent dorsi-medial region, where further blood accumulates as part of the pool from which venous return flow can be driven.
