Autoinjector, has timer adapted to delay predetermined time during operation of moving device of reservoir by shutter after injection of fluid, and to delay withdrawal of needle in predetermined time after end of injection

摘要

The autoinjector has a lower body for receiving a reservoir (9) containing fluid. Injection units (5) inject the fluid through a needle when the needle is in an injection position. A moving device moves the reservoir to retract the needle from a body of a user after injecting the fluid. A timer is adapted to delay a predetermined time during operation of the moving device of the reservoir by a shutter (19) after injection of the fluid and to delay the withdrawal of the needle in predetermined time after the end of injection.
