Cannula inserter comprising a casing (5) with a distal end, intended to be placed in proximity to the skin of a patient, and an opposite proximal end, a pistion (1) fixed at least temporarily by retaining means (9), drive means designed to exert a propulsion force of the piston (1) in the direction counter to the trigger (4), and release means (8) intended to release the piston (1); the inserter additionally comprising a needle (10) fixed to a support (2); the piston (1) being mounted in the casing (5) in such a way that, once released, it reaches and remains temporarily in a first position, then a second position; the needle (10) and its support (2) also being arranged so as to be able to be driven by the piston (1) in a direction corresponding to the main orientation (12) of the casing (5), before the piston (1) reaches said first position, and so as to be able to effect an automatic rotation about an axis perpendicular to said main orientation (12) during the movement of the piston between said first position and said second position. |
