USPTO Abstract

A device for mixing a main medical substance with a secondary substance comprises an internally hollow main body (5) having an open end (51), through which a hermetically sealed vial (2) containing a main medical substance can be inserted, and a closed end (52), opposite the open end, comprising a dispensing body (10) or a closing element (11) which can be opened; the main body (5) comprises at least one housing area (8) within which said vial (2) can be inserted, and at least one capsule (6) containing a secondary substance to be mixed with the main substance. The vial (2) has a closure (3) with a pierceable septum (4). A perforating element (7) is arranged inside the main body (5) to perforate the at least one capsule (6) of a secondary substance and the septum (4) of the vial (2). The main body (5) further comprises, therein, a mixing chamber (9), located between the perforating element (7) and the closed end (52), in which the secondary substance is completely mixed with the main substance to make a mixed substance (26). The main body (5) has, in the housing area (8), thickening elements (16) adapted to make temporary stops to keep the at least one capsule (6) and the vial (2) in a position distant from the perforating element (7).
