Abstract
A needleless access device includes a housing having a fluid pathway and an inner chamber. A biased plunger is disposed within the inner chamber and movable between a first position and a second position, and a main seal seals the inner chamber from the fluid pathway. A vent between the inner chamber and the outside of the housing allows air to pass out of and into the inner chamber when the plunger is moved between the first and the second positions.
