Classification: CPC A | IPC A

Claim 7:
8. A multi-use drug delivery device according to claim 1,
wherein the connected configuration further comprises a gas filled state and a fluid-filled state, wherein the gas-filled state comprises the flow channel is filled with air, and, wherein the fluid-filled state comprises the flow channel is partly filled with the fluid drug, and defines a first flow resistance for fluid flowing in the flow channel,, wherein the equalizing flow path from the external environment define a second flow path having a second flow resistance for gas flowing from the external environment to the fluid communication volume, wherein the second flow resistance is smaller than the first flow resistance, whereby the gas flow along the equalizing flow path will be larger than the fluid flow along the second flow path, in response to a pressure drop in the fluid communication volume.
