Abstract
The disclosure refers to a device, for example a cartridge, a syringe or an autoinjector, which reduces the possibility of user error and provides an easy and automatic operation during mixing and/or reconstitution. The device is adapted such that activation of the device causes movement one of a first piston and a second piston in second chamber in an axial direction of the device, thereby moving the other one of the first piston and the second piston into the same axial direction of the device, opening a fluid communication path between the second chamber and a first chamber of the device, and expelling a second material from the second chamber into the first chamber via the fluid communication path. The disclosure is further directed to a respective mixing and/or reconstitution method.
