Automatic Injection Device

摘要

The present invention relates to an automatic injection device (1) comprising: a container aligned on a longitudinal axis A and movable between a first position and a second position, in which the needle is inserted, biasing means, laterally spaced with respect to said longitudinal axis A, and coupled to the container for moving it to its second position, via linking means, retaining means (70) for maintaining said biasing means in a first stressed state, deactivating means (80) capable of moving along a transversal direction for releasing said retaining means, triggering means (90) for releasing said deactivating means.

1. A device for injection of a product into an injection site, said device comprising:
a housing having a longitudinal axis A and receiving a container for the product to be injected, said container being aligned on said longitudinal axis A, said container being substantially closed at a proximal end by a stopper, said stopper being capable of being moved distally within said container so as to expel the product to be injected, and at a distal end by a needle for the exit of the product to be injected, said container being movable with respect to said housing between a first position, in which the needle does not extend beyond a distal end of the housing, and a second position, distally spaced with respect to said first position, in which the needle extends beyond the distal end of the housing, a biasing element coupled to said housing and structured to produce a distal force along a longitudinal axis B when g transitioning from a first state to a second state, said second state being less stressed than said first state, said longitudinal axis B being laterally spaced with respect to said longitudinal axis A along a transversal direction R, a linking element for coupling said biasing element to said container at least from said first position to said second position of the container, said linking element being shaped and dimensioned so as to transmit said distal force to said container when said biasing element transitions from said first state to said second state so as to move said container from its first position to its second position, a retainer element coupled to said container and to said housing in the first position of the container, for releasably maintaining said biasing element in said first state, said retainer element being capable of moving from a passive condition, in which it maintains said biasing element in said first state, to an active condition, in which said biasing element is free to transition to said second state, wherein the device further comprises a deactivating element coupled to said retaining element, capable of moving with respect to the retainer element from a first position, in which said retainer element is in a passive condition, to a second position, offset from said first position along said transversal direction R, in which said retainer element is in said active condition, and a trigger element for moving said deactivating element from said first position to said second position.
