Locking device between a non-sterile area and a sterile area

摘要

A locking device between a non-sterile area and a sterile area with a boundary between the two areas is proposed, through which at least one movable drive element, which can be driven to move from the non-sterile area, extends into the sterile area. The drive member is surrounded at least in a section area by a channel through which a medium can be passed. The channel is open to the sterile area via at least one opening at an end area which extends into the sterile area. As a medium, a sterilization or protective medium, e.g. B. in operation air, introduced through the at least one opening in the channel and sucked through the channel to the non-sterile area.
