Abstract

The present invention relates to an automatic injection device (1) comprising : a container (2) having a longitudinal axis A and movable between a first position and a second position, in which the needle is inserted, biasing means (8), for moving the container to its second position, retaining means (70, 74, 74b) for maintaining said biasing means in a first stressed state, triggering means (90, 91 e) for releasing said retaining means, said retaining means comprising a lever member having a rotatable cylinder part and a radial projection extending therefrom, said radial projection being in a first angular position when said retaining means is in its passive condition, said radial projection being in a second angular position, different from said first angular position, when said retaining means is in its active condition, said rotatable cylinder part being included in a transversal plane of said longitudinal axis A.

Description

technical field [0001] The present invention relates to a device for injecting a product, the needle insertion step being automatic and performed with minimal effort by the user. Background technique [0002] In this application, the distal end of an element or device refers to the end furthest from the user's hand when said element or device is in the use position, and the proximal end refers to the end closest to the user's hand. Similarly, in this application, the terms "in the distal direction" and "distal" refer to the direction of injection, and the terms "in the proximal direction" or "proximal" refer to the direction opposite to the direction of injection . [0003] Devices for the automatic injection of products, also known as autoinjectors, are widely used in the medical field where daily injections are required, such as some treatments for diabetes, and in medical fields where patients often need to perform these injections themselves. Since the patient is not a...
