Abstract
A devious path bacterial barrier for providing an air/gas pathway to a sterile environment from an external environment, including a flat member lying within a plane and having spaced openings extending into the flat member and with one of the openings for communicating with the exterior environment and with the other of the openings for communicating with the sterile environment, a pathway extending between the openings and with the pathway extending within the flat member and along the plane of the flat member for interconnecting the openings and providing an air/gas pathway between the one opening of the flat member and the other opening, and the pathway including a plurality of bends along its length and with each bend providing an area to trap any bacteria introduced into the pathway from the exterior environment communicating with the one opening and with all the bacteria trapped at a distance along the pathway before the other opening communicating with the sterile environment.
