Abstract

The invention relates to an automatic injection device (1) for a product contained in a container (50), comprising: - a housing (8, 19) receiving the container (50), the container being movable between an initial position and an insertion position, - triggering means (23) for initiating the movement of said container (50) from its initial position to its insertion position, said triggering means (23) being in one of a passive state, in which application of a force on said triggering means does not initiate movement of said container (50), and an active state, in which application of said force on said triggering means does initiate said movement, and - a safety shield (10) movable with respect to said housing (8, 19) between a first position and a second position, movement of said safety shield (10) from its first position to its second position placing said triggering means (23) in its active state, characterized in that said device comprises: an indicator (19c, 13) that provides an indication to a user of the device (1) that the safety shield (10) has reached its second position.

Description

technical field

[0001] The present invention relates to a device for the automatic injection of a product, in particular for self-injection, in a very safe manner. Background technique

[0002] In this application, the distal part of a component or device refers to the end farthest from the user's hand, and the proximal part refers to the end closest to the user's hand. Likewise, in the present application, "distal direction" refers to the direction of injection, and "proximal direction" refers to the direction opposite to the direction of injection.

[0003] Some diseases require, for example, timed injections of drugs or products on a daily basis. To simplify treatment, some auto-injectors have been provided to allow patients to administer the injections themselves.

[0004] Of course, since the patient is neither a nurse nor an educated person in the field of medical devices, it must be shown that this self-injector is very easy to use and very safe. In particular, the...
