Injection device (1) for administering a dose of a liquid medicine (M) comprising: - a syringe (3) containing the dose of the medicine (M) - a hollow injection needle (4) adapted to penetrate the skin of the patient, - a stop (6) arranged so that it can move inside the syringe (3), - a plunger (9) that can be connected to the stop (4) and can be moved in at least one direction (P) proximal to move the stop (4) in the proximal direction (P) and - a releasable noise component (28) capable of, at release, generate an audible and / or tactile response, in which the proximal movement of the stop ( 4) causes the dose of the medication (M) to be ejected through the hollow injection needle (4) and the noise component (28) is released when the plunger (9) (4) reaches a position relative to the syringe (3) in which the stop (4) is located in the vicinity of a proximal end of the syringe (3), and in which the noise component (28) lib erado impacts on at least one component of the injection device (1) to generate the audible and / or tactile response indicating the end of the injection characterized by the component of the injection device (1), where the component (28) impacts of released noise, it comprises at least part of an activation button (13). |
