1. A sealing device for sealing a passage for a medical instrument, with:
a fastening area for fastening the sealing device on a tube or another medical appliance; a sealing area which is at least either designed to bear on the circumference of a medical instrument inserted into the sealing device or is designed to close the sealing device when no medical instrument is inserted into the sealing device; a first elastic wall enclosing the sealing area in a ring shape, with an annular first edge, which is connected to the sealing area, and an annular second edge; a second elastic wall which encloses the first wall in a ring shape and is spaced apart therefrom, with an annular first edge and an annular second edge, which is connected to the fastening area; an annular transition area, which connects the second edge of the first wall to the first edge of the second wall, wherein the transition area has a wall thickness greater than the first wall and greater than the second wall; wherein the sealing area comprises a slit membrane for closing the sealing device when no medical instrument is inserted into the sealing device, and a ring seal designed to bear on the circumference of a medical instrument inserted into the sealing device; and an outer edge of the slit membrane is arranged directly behind the ring seal with respect to the direction of insertion in which a medical instrument is to be inserted into the sealing device. |
