The invention concerns an injection device comprising a syringe body (1) defining a chamber designed to be filled with liquid, and a member (25) for dispensing the liquid including an end bit sealing said chamber extended by a hub bearing an injection needle protected by a protective cap (35), said dispensing member being axially mobile between a position sealing the chamber and a position for injecting the liquid. The invention is characterised in the dispensing member (25) comprises an intermediate section (31) between the hub and the sealing end bit, and the syringe body (1) comprises a ring (6) defining two superposed compartments (18, 19) each capable of housing said intermediate section. Moreover, the protective cap (35) and said intermediate section (31) have matching cam-shaped profiles (34, 38) for generating an axial displacement of the dispensing member (25) towards its injecting position when said protective cap rotates.
L'invention concerne un dispositif d'injection comprenant un corps de seringue (1) délimitant une chambre destinée à être remplie de liquide, et un organe (25) de distribution du liquide comportant un embout d'obturation de ladite chambre prolongé d'une embase portant une aiguille d'injection protégée par un capuchon de protection (35), ledit organe de distribution étant mobile axialement entre une position d'obturation de la chambre et une position d'injection du liquide. Selon l'invention, l'organe de distribution (25) comprend un tronçon (31) intermédiaire entre l'embase et l'embout d'obturation, et le corps de seringue (1) comprend une bague (6) délimitant deux compartiments superposés (18,19) aptes à loger chacun ledit tronçon intermédiaire. De plus, le capuchon de protection (35) et ce tronçon intermédiaire (31) présentent des profils complémentaires (34,38) en forme de came aptes à permettre d'engendrer un déplacement axial de l'organe de distribution (25) vers sa position d'injection lors d'une rotation dudit capuchon de protection.
