Abstract
A continuous vent for an endoscope which always allows flow of gas in order to prevent damaging differential pressures and always prevents entry of liquid into the endoscope. A barrier for this purpose overlays a vent port and is held in place by a ring-shaped spacer which with an overhanging shoulder leaves a limited space for flow of fluid and excludes most particulates from the barrier. The barrier maybe an assortment of hydrophobic and hydrophilic layers.
