Abstract
The present invention relates to a tourniquet (1) comprising: • a support (2) for surrounding a first portion of a limb, • an elastic sleeve (4) to be held in a stretched position around the support (2), the support (2) preventing contraction of the elastic sleeve (4), • a grip element (8) which is movable relative to the support (2), • a drive element (6) for driving the elastic sleeve (4), when the grip element (8) is moved manually relative to the support (2), from its stretched position around the support to a blood vessel constricting position wherein the elastic sleeve (4) surrounds a second portion of the limb, adjacent to the first portion of the limb but not surrounded by the support (2), in such a way that the elastic sleeve (4) can contract by resilient return, and thus compress the second portion of the limb.
