Abstract
An autoinjector having a body (1) adapted to receive a reservoir containing fluid and including a piston (P) and a needle. The body (1) has a distal portion, a middle portion, and a proximal portion, the middle portion including at least one middle window (12) making it possible, before use, to see 100% of the fluid contained in the reservoir and, after injection, to see the piston (P). The middle window (12) has an external shape of an arrow that points towards the proximal portion. The proximal portion (121) of the middle window (12) includes a triangular end portion, forming the point of the arrow, the base of the triangular end portion, remote from the point, forms the widest portion of the middle window (12).
