Abstract

An adapter for a disposable water bottle for an endoscope having a cap with threads suitable for attachment to threads on a neck of the water bottle, an outer tube affixed to an opening in the cap, and an inner tube extending through the outer tube. The inner tube forms an air passing annulus on an interior of the outer tube. The inner tube extends outwardly of an end of the outer tube and through the opening in the cap. A fitting is non-removably affixed to an end of the inner and outer tubes opposite the cap. The fitting is adapted for attachment to air and water connections of the endoscope. The outer tube, the inner tube and the cap are formed of a polymeric material.

Claims

1. An adapter apparatus for a disposable water bottle for an endoscope comprising:

a cap having threads suitable for attachment to threads on the neck of a water bottle;

an outer tube affixed to an opening in said cap;

an inner tube extending through said outer tube, said inner tube forming an air passing annulus on an interior of said outer tube, said inner tube extending outwardly of an end of said outer tube and through said opening in said cap;

a fitting non-removably affixed to an end of said inner and outer tubes opposite said cap; and

an adapter body removably affixed to said fitting, said adapter member having a first female connector and a second female connector, said adapter body having a receptacle formed at one end thereof, said adapter body having an opposite end for connection to an air line and a water line of an endoscope, said fitting affixed in fluid-tight relationship within said receptacle of said adapter body, each of said first and second female connectors opening in side-by-side spaced relationship at said opposite end of said adapter body, said adapter body having a water channel communicating with said second female connector and extending through said adapter body so as to open at said one end of said adapter body and connected with an interior of said inner tube through said fitting, said adapter body having an air passing channel communicating with said first female connector and extending through said adapter body so as to open at said one end of said adapter body and connect with said air passing annulus, said inner tube being interior of said air passing annulus within said fitting, said adapter body being formed of a generally transparent rigid polymeric material.

2. The adapter of claim 1, said outer tube having an outer surface affixed in air-tight relationship with said opening of said cap.

3. The adapter of claim 1, said inner tube extending continuously through said outer tube.

4. The adapter of claim 1, said outer tube, said inner tube and said cap being formed of a polymeric material.

5. The adapter of claim 1, said inner tube having an anchor member affixed to an end of said inner tube extending outwardly from said outer tube.

6. The adapter of claim 5, said anchor member being adhesively affixed to said inner tube, said fitting being adhesively affixed to said inner and outer tubes.

7. The adapter of claim 6, said anchor member being ultraviolet glued to said inner tube, said fitting being ultraviolet glued to said inner and outer tubes.
