| abstract |
The invention proposes a device (1) for dispensing a substance, in particular to a patient, comprising a cylindrical first container (2) containing the substance and a second container (3) containing a liquid. Said device further comprises an injection device (4) and transfer means (5) for transferring the liquid from the second container (3) to the first container (2) and from the first container (2) to the injection device (4). The first container (2) has, on a first end, a connection element (7) and a plunger (9) that can be moved between the first (6) and a second end (8). By moving the plunger (9) towards the first end (6) of the first container (2), a liquid contained therein can be dispensed via the injection device (4). The device is further characterised in that the injection device (4) comprises a piercing cannula (15) and an indwelling cannula (16), wherein in an initial position, a distal end region of the piercing cannula (15) extends coaxially in the interior of the indwelling cannula (16). |
