Abstract: In an apparatus for treating vascular, metabolic and functional imbalance, and edema of a limb by variation in pressure of a high-density fluid around the limb, a fluid-tight flexible bag serves to protect the limb to be treated and a filling bag delimits a filling enclosure with the protective bag. The apparatus includes a pump for producing upward and downward displacement of the fluid within the enclosure between a bottom level, a top level and intermediate levels, a timing circuit for maintaining the fluid at predetermined levels during predetermined periods of time, and a programmable logic circuit for adjusting the levels of fluid within the enclosure. An electronic variator are employed for regulating the speeds of upward and/or downward displacement of the fluid within the enclosure in respect of different levels.

Abstract: Apparatus for the treating of oedemata by which the bad limb is immersed vertically in a tub of mercury. An impermeable flexible sleeve is sealed to the edge of the tub. Fluid under pressure is admitted at the top of the tub into the space between the tub and the sleeve so that its pressure may add itself to the static pressure of the mercury, which increases from top to bottom.
