Abstract
The present invention relates to a device (1) for automatic injection of a product (3) and a needle (6). The device comprises:—a housing (8) for the container (5), the container being movable relative to the housing between an initial position, in which a tip of the needle does not extend beyond a distal end of the housing and in which the container is in one of a passive state and an active state, to an insertion position, distally spaced relative to the initial position and in which the tip of the needle extends beyond the distal end of the housing, movement of the container out of its first position being prevented when the container is in its passive state, and being permitted when the container is in its active state, and—a safety shield (10) coupled to the housing (8) for movement between a first position and a second position in which the tip of the needle does not extend beyond a distal end of the shield—a needle shield (2) coupled with said housing and covering the needle prior to use of said device, removal of said needle shield being with limited or no rotation of said needle shield.
