Abstract
A piercing device for an administration device includes an elastic element with which a biasing force may be generated for piercing, a base, and a cannula unit which may be movable relative to the base in a piercing direction from a safety (secured) position, where the cannula unit may be subjected to the biasing force in the piercing direction. The administration device further includes a securing element by which the cannula unit, subjected to the biasing force, may be held in the safety position and which has a thermosensitive region that may be deformable under mechanical stress when heated, and a heating element with which the thermosensitive region of the securing element may be heated, such that the thermosensitive region of the securing element may deform in response to the biasing force and, as a result, the cannula unit may move away from the safety position in the piercing direction.
