A DRUG MIXING DEVICE

摘要

A drug mixing device (1) for mixing a dry drug, such as a lyophilized drug, with a liquid, thereby forming a liquid drug. The device (1) comprises a reservoir (2) containing a liquid, a vial holder (3) for receiving a vial (4) containing a dry drug, means (5, 7) for establishing a 5 fluid connection between the reservoir (2) and a vial (4) positioned in the vial holder (3) , means (8, 18) for forcing the liquid from the reservoir (2) to a vial (4) positioned in the vial holder (3) , and means (24, 9) for equalizing a pressure in the vial (4) . Transferring liquid from the reservoir (2) to the vial (4) causes the dry drug to become reconstituted. At least the reservoir (2) , the vial holder (3) , the means (5, 7) for establishing a fluid connection and (10) the forcing means (8, 18) form an at least substantially integral device.
