Abstract
A transfer device for transferring a medical fluid from a vial to a medical fluid injection device includes a vial holder where a vial spike positioned within the vial holder is configured to enter a vial containing a medical fluid when the vial is inserted into the vial holder. An expansion chamber having an interior cavity is in fluid communication with the vial spike. A pressurized gas cartridge is positioned with the interior cavity of the expansion chamber, while a puncture tip is configured to puncture the pressurized gas cartridge when actuated by a user. The vial spike is also configured to be in fluid communication with an injection device attached to the transfer device.
