Safety Device for Shielding an Injection Needle of a Medical Container, and an Injection Device Including This Safety Device

Abstract

The safety device includes a tubular body extending along a longitudinal axis. The tubular body is configured to receive the medical container, a needle cover movable relative to said body between a retracted position, and an extended position in which the needle cover distally extends from the retracted position in order to shield the injection needle after activation of the safety device, a release element configured to move the needle cover from the retracted to the extended position after activation of the safety device, and a retainer for maintaining the release element in a compressed condition when the needle cover is in the retracted position. The retainer is configured to transmit a user's activation force to the needle cover once the injection operation is completed. The needle cover includes a distal abutment surface, and the device includes only two bumps protruding from the body, the two bumps having a proximal abutment surface, the distal abutment surface of the needle cover abutting against the proximal abutment surface of these only two bumps in the retracted position of the needle cover.
