1. A training device for medicine injection devices, the training device comprising:
- a body having a proximal end and a distal end and a cavity formed in the body;
a shield having a proximal end and a distal end, the shield being slidably attached to the body, slidable between a retracted position exposing a pin arranged at the distal end of the body and directing from the distal end of the body, and an extended position covering the pin;
a spring coupled to the body and the shield, the spring biasing the shield to enable the shield to advance toward the extended position;
releasable cooperating first locking members on the body and the shield for engaging the body with the shield to hold the shield in the retracted position;
releasable cooperating second locking members on the body and the shield for engaging the body with the shield to hold the shield in the extended position; and
a reset base configured to receive a distal end of the training device, the reset base having a release ramp for disengaging the releasable cooperating second locking members when the reset base and the training device are assembled,wherein the training device further includes a plunger slidably arranged in the cavity of the body and having a compressible element adapted to exert a force when the plunger is moved in the cavity towards the distal end of the body, the force corresponding to an injection resistance of a medicine injected into a patient.

Abstract
The training device for medicine injection devices comprises a plunger slidably arranged in the cavity of a body. The plunger comprises a compressible element arranged at a distal end of the plunger and adapted to provide a resistance between compressible element and inner wall if the cavity of the body when the plunger is moved in the cavity towards the distal end of the body. The resistance corresponds to an injection resistance of a medicine injected into a patient. The invention also comprises a reset device for resetting the training device from a used status to a condition for reuse.
