Perforating device

A double-needle perforating device for bottles containing a medical liquid and provided with a pierceable closing septum, comprising

• a linear guide element of a longitudinal axis
• a kit slidable along the longitudinal axis of the guide and provided with at least two accesses for connection to respective fluid lines for transfer of the medical fluid and/or a second fluid,
• at least two perforation needles integral with a movement of the sliding kit, comprising a first needle for a passage of the medical liquid and a second needle for a passage of the second fluid, the first and second needles communicating respectively with the accesses and being movable along at least one sliding axis,
• a needle lock element connected to the guide element and provided with
• at least one abutment surface adapted to prevent the passage of the perforation needles and
• at least a first hole adapted instead to allow the passage of the perforation needles,
• the needle lock being movable to pass from a locking position in which an abutment surface is aligned with the perforation needles and prevents the passage thereof in response to a possible longitudinal sliding of the kit along the guide, to a permitted passage position in which the first hole is aligned with the sliding axis of the perforation needles and allows the passage thereof in response to a longitudinal sliding of the kit along the guide.
