Abstract

L'invention concerne un système d'aspiration ou d'injection de sécurité incorporant un garrot, qui est constitué d'un certain nombre de bandes gonflables rattachées parallèlement les unes aux autres, les positions de rattachement à l'endroit où les bandes sont reliées entre elles étant des parties pliables, avec une compresse disposée à la fois au milieu du bord extérieur de chaque bande et sur le bord intérieur de l'une ou l'autre de leurs extrémités libres, d'un insufflateur, qui comporte un compresseur d'air et un contrôleur, ledit contrôleur commandant le compresseur d'air avec ou sans fil. Selon l'invention, le compresseur d'air est relié à chaque bande gonflable par des tuyaux d'air, ainsi qu'à un injecteur, qui peut être un cylindre de seringue, une aiguille à ailettes, une aiguille à fistule artério-veineuse (AV) ou une aiguille intraveineuse.
