Abstract
A valve for use in irrigating, accessing and sealing the instrument channel of an endoscope is disclosed. The valve is adapted for installation onto an endoscope instrument inlet port. The valve includes a body, a flip cap, and a seal curtain. The body has an open end adapted for connection to the inlet port, interior walls defining an cavity, and an outer surface defining a valve entry port. The entry port is connected to a channel open to the cavity. The flip cap is removably connectable to the valve entry port and has a slit therethrough. The seal curtain contains a flexible cylindrical portion, and a lid at one end, and is removably insertable into the cavity. A longitudinal axis of the seal curtain in an installed position within the cavity is at an angle with respect to a longitudinal axis of the body.
