The invention relates to a disposable injection device consisting of: a tubular container (1) which is equipped with impervious sealing means (10, 15), said container defining a chamber that is intended to be filled with a liquid and comprising a liquid-dispensing conduit (13) which opens out into said chamber; a needle-holder base (20) which contains therein a conduit (29) for supplying liquid to the needle and which can move axially between a retracted position in which the dispensing conduit (13) is sealed and a forward injecting position in which the liquid can flow from the chamber towards the needle (28); a suitably-shaped cap (30) for covering the base (20), which is provided with removable means (35) of connecting to the tubular container (1); axial stop means (32) which are disposed such as to hold the base (20) in the sealing position thereof when the latter is covered with the cap (30); and axial stop means (23) which are disposed so as to limit the axial travel of the base (20) once the cap (30) has been removed.
L'invention concerne un dispositif d'injection à usage unique comprenant un récipient tubulaire (1) doté de moyens d'obturation étanche (10, 15) délimitant une chambre destinée à être remplie d'un liquide, et comportant un conduit de distribution de liquide (13) débouchant dans ladite chambre, une embase porte-aiguille (20) percée d'un conduit d'alimentation en liquide (29) de ladite aiguille et mobile axialement de façon à pouvoir se déplacer entre une position reculée où le conduit de distribution (13) est obturé, et une position avancée d'injection, où elle autorise l'écoulement du liquide de la chambre vers l'aiguille (28), un capuchon (30) de forme adaptée pour coiffer l'embase (20), doté de moyens (35) de liaison détachable avec le récipient tubulaire (1), des moyens de butée axiale (32) disposés de façon à maintenir l'embase (20) dans sa position d'obturation lorsque cette dernière est coiffée dudit capuchon (30), et des moyens de butée axiale (23) disposés de façon à limiter la course de déplacement axial de l'embase (20), une fois le capuchon (30) retiré.
