Abstract
A needle-free injection system, including an injection device and a vial adapter. The injection device is configured to be loaded with a dose of injectable fluid and forcibly inject such dose into an injection site. The vial adapter is configured to secure to and selectively seal a vial containing an external supply of injectable fluid. The vial adapter also includes a flexible adapter structure biased into a blocking position. The injection device includes a filling adapter configured to move the flexible adapter structure out of the blocking position to thereby permit the vial adapter and injection device to be secured together in an engaged configuration. In this engaged configuration, a dose of injectable fluid may be drawn from the external supply of injectable fluid into the injection device.
