Abstract
Device for stimulating venous return in the lower limbs including a frame (1) intended to rest with a supporting surface against a foundation such as a floor, a bed head, a wall etc. The device is distinguished in that a foot plate (4) is arranged to tilt on frame (1) from an starting position that is angled in relation to the floor and thus frame (1) around an axle (5), that foot plate (4) is provided with a leaf spring (9) acting between a section (7) of the frame and the underside of foot plate (4), that the section (7) has such a form that when foot plate (4) pivots from the said starting position, leaf spring (9), by being progressively tensioned by the interaction of the frame with the section of the spring, increases the resistance against the pivoting of foot plate.
