A mechanism is provided for compressing the compressible annular seal to provide an airtight seal across the at least one channel. A duckbill flap valve is also positioned in the at least one channel adjacent to the compressible annular seal to receive the medical device after its insertion through the central aperture of the compressible annular seal.
