1. A device for opening an ampoule having an ampoule body and an ampoule head, the device comprising:
a hollow cylinder housing having a proximal end, a distal end, and a side wall, the housing defining a longitudinal axis extending from the proximal end to the distal end, the housing delimiting an interior for accommodating an ampoule; and a rotary element configured to be rotated about the longitudinal axis relative to the housing in an actuating direction, the rotary element having a proximal section and a fragmentation section connected to the proximal section, the hollow cylinder housing having a first guiding structure with a first guiding surface that is directed toward the interior of the housing, the first guiding surface having a distance from the longitudinal axis that continuously decreases over a first angular range along a circumferential direction, the first guiding surface being arranged in a first side wall region of the hollow cylinder housing so as to press the fragmentation section radially inward when the rotary element is rotated in the actuating direction, the first guiding structure being formed by at least one radial protrusion of the side wall projecting into the interior. |
