Abstract
(EN)
The invention relates to an automatic injection device (1) comprising: -a container (6) provided with a needle (8); -a housing (3) receiving a container (6) movable relative to said housing (3) between an initial position to an insertion position; -a needle shield (12) for receiving said needle (8) and in which the needle (8) is embedded prior to use of said device (1); -a deshielder (33) coupled to said needle shield (12) by first connecting means (51) and removably assembled to the distal part of the housing (3) by second connecting means (44, 45a, 45b, 57), characterized in that: said first and second connecting means are designed so that a rotational movement of the deshielder (33) about the device axis (2) of the device (1) with respect to the housing (3) causes an axial displacement of the needle shield (12) in the distal direction with substantially no rotational movement of the needle shield (12) with respect to the needle (8).
(FR)
L'invention concerne un dispositif d'injection (1) automatique qui comprend: un contenant (6) pourvu d'une aiguille (8); un corps (3) qui reçoit amovible le contenant (6) par rapport audit corps (3) entre une position initiale et une position d'insertion; un élément de protection (12) d'aiguille servant à recevoir ladite aiguille (8) et dans lequel l'aiguille (8) est intégrée avant l'utilisation du dispositif (1); un élément de déprotection (33) couplé à l'élément de protection (12) d'aiguille par des premiers moyens de liaison (51) et assemblé amovible à la partie distale du corps (3) par des deuxièmes moyens de liaison (44, 45a, 45b, 57). Le dispositif est caractérisé en ce que les premier et deuxième moyens de liaison sont conçus pour produire, lors de la rotation de l'élément de déprotection (33) autour de l'axe (2) du dispositif (1) par rapport au corps (3), un déplacement axial de l'élément de protection (12) d'aiguille dans le sens distal, l'élément de protection (12) d'aiguille ne tournant pratiquement pas par rapport à l'aiguille (8).
