| 发明名称 | Safety device for a pre-filled syringe and an injection device | ||
| 摘要 | According to the invention, a safety device for a pre-filled syringe comprises of a support body adapted to mount the pre-filled syringe, a first needle shield slidably arranged with respect to the support body and a second needle shield slidably arranged with respect to the support body and releasably retained in a retracted position (PR). A proximal movement of the first needle shield with respect to the support body releases the retention of the second needle shield in the retracted position (PR), so that the second needle shield is allowed to slide in the distal direction towards an advanced position (PA). | ||

| 主权项 | 1. A safety device for a pre-filled syringe comprising a support body adapted to mount the pre-filled syringe, a first needle shield slidably arranged with respect to the support body and a second needle shield slidably arranged with respect to the support body and releasably retained in a retracted position (PR), wherein a proximal movement of the first needle shield with respect to the support body releases the retention of the second needle shield in the retracted position (PR), characterized in that the second needle shield comprises a helical recess accommodating a projection of the support body so that the second needle shield is allowed to slide parallel to a central axis (A) of the safety device in the distal direction towards an advanced position (PA) wherein the helical recess is configured to force the second needle shield to rotate with respect to the support body when the second needle shield is allowed to slide parallel to a central axis (A). | ||
