Abstract

Disclosed is an administration device able to transition between a static state and an advancing state. The administration device includes a stopper and an actuator with a post, both disposed within a hollow body that has a sidewall disposed radially within along its longitudinal length. The actuator and post can move axially within the hollow body. The stopper has a primary wall configured to exert a pressure to seal against the sidewall when the post is in a first position. This seal can provide an aseptic barrier and prevent communication of contaminating particles such as pathogens, pyrogens, viruses, bacteria, and across the seal.
