ABSTRACT:
Device and method for venous-flow stimulation, through localized periodic application of squeezing forces, essentially limited to the phalanx of the digits and thumb, and to the adjacent region of the palm of the hand. To this end, an inflatable mitt is applied to the said phalanx and adjacent regions, with digits and thumb projecting beyond the mitt. The mitt may be wrapped with suitable fabric, such as surgical gauze or muslin, to provide a circumferential tie of the inflatable regions, the tie providing hoop-tension reference for inward application of a squeezing pressure/release cycle; and the squeeze is applied in unison circumferentially around each of the individual digits (and thumb) at the phalanx region. Altervatively, the inflatable mitt may be embedded in an orthopedic cast, without impairing the application of pulsed pressure local to the indicated region in this case the circumferential tie is provided by the case. In either case, arterial throughput is also noted, concurrent with such venous-flow stimulation, and the arterial throughput is enhanced when the stimulating pulse is sustained for a brief period prior to a relaxation dwell between pulses.
