Irrigating biopsy inlet valve
First Claim
1. An irrigating biopsy inlet valve for providing sealable access to an instrument channel of an endoscope, the valve comprising:
- a. a body having a first end, a second end, and an outer circumferential surface and defining an internal passage leading from said first end to said second end, wherein said second end is adapted for connection to an endoscope instrument channel inlet port;
b. a cap having a center aperture therethrough and removably connectable to said first end for providing sealable access to said internal passage; and
c. a flap member internally mounted to said body in said internal passage, wherein said flap member inhibits fluid movement in a direction from said instrument channel to said first end of said body;
d. wherein a fluid may be dispensed through said internal passage in a direction from said first end to said second end to irrigate said instrument channel.

Abstract
A valve for use in irrigating, accessing and sealing the instrument channel of an endoscope is disclosed. The valve includes a body having a first end, a second end, and an outer circumferential surface. The second end is adapted for connection to an instrument channel inlet port. The outer circumferential surface may define a side entry port. The valve includes a flip cap having an aperture therethrough. The cap is removably insertable into the first end for providing sealable access to the internal passage. The valve may include a tube having an inlet end, an outlet end, and a check valve disposed at the inlet end. The outlet end is fixed to the side entry port. A fluid may be dispensed through the check valve to irrigate the instrument channel. The valve may include a seal curtain member for providing sealable access to the instrument channel.
