DISPOSABLE INJECTION DEVICE DESIGNED TO BE PRE-FILLED

摘要

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.
