Title: AUTOMATIC INJECTION DEVICE PROVIDED WITH A DEVICE FOR GENERATING SOUND SIGNALS
Abstract:
The invention concerns an automatic injection device (1) comprising an injection syringe (3) for injecting liquid (4) provided with a syringe body (5) carrying an injection needle (6) and a piston (7) rod (7a) mounted so as to be able to move inside this syringe body (5) in order to cover an injection stroke during which the liquid (4) is injected, an external casing (9) and a positioning control member (11) that are telescopic, the relative movement of which controls the operation of the automatic injection device (1), and control members (13, 15) arranged to selectively control the movement of the syringe body (5) and the movement of the piston (7) inside the positioning control member (11) in order to automatically inject the liquid (4) present in the injection syringe (3), the automatic injection device (1) further comprising a device (17) for generating sound signals activated during the automatic injection of the liquid (4) present in the injection syringe (3) so as to generate a series of sounds signals from the start to the end of the injection.
