Abstract
Abstract An apparatus for cleaning an endoscope comprises an upper spray head which is disposed toward the central axis of a rinse vessel, and a lower spray head disposed toward the wall of the rinse vessel. A portion of an endoscope is disposed around the central axis of the rinse vessel, and the spray heads direct a cleaning liquid toward the endoscope portion from above and below in an oblique direction while rotating about the central axis. The spray heads do not have to be removed to place or remove an endoscope portion to be cleaned.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
236 words
An apparatus for cleaning an endoscope, said apparatus comprising: a rinse vessel adapted to receive a portion of an endoscope to be cleaned, said rinse vessel having a center and an outer wall; support means in said rinse vessel defining a conical support plane around said center of said rinse vessel, said support means being for supporting one or more endoscope portions in said conical support plane; first and second spray heads; said first spray head being disposed in said rinse vessel relatively near said center of said rinse vessel as compared with said second spray head and second spray head being disposed in said rinse vessel relatively near said outer wall as compared with said first spray head; said first spray head including means for spraying the endoscope portion in a first direction generally perpendicular to said conical support plane when the endoscope portion is supported in said support plane, and said second spray head including means for spraying the endoscope portion in a second direction generally perpendicular to said conical support plane when the endoscope portion is supported in said support plane, said first and second directions being directly opposite to each other; means for feeding liquid to said spray heads; and drive means for rotating said spray heads about said center of said rinse vessel and said spray heads rotating in respective parallel planes with respect to which said support plane is inclined.
Claim 2
Independent Claim
236 words
An apparatus for cleaning an endoscope, said apparatus comprising: a rinse vessel adapted to receive a portion of an endoscope to be cleaned, said rinse vessel having a center and an outer wall; support means in said rinse vessel defining a conical support plane around said center of said rinse vessel, said support means being for supporting one or more endoscope portions in said conical support plane; first and second spray heads; said first spray head being disposed in said rinse vessel relatively near said center of said rinse vessel as compared with said second spray head and second spray head being disposed in said rinse vessel relatively near said outer wall as compared with said first spray head; said first spray head including means for spraying the endoscope portion in a first direction generally perpendicular to said conical support plane when the endoscope portion is supported in said support plane, and said second spray head including means for spraying the endoscope portion in a second direction generally perpendicular to said conical support plane when the endoscope portion is supported in said support plane, said first and second directions being directly opposite to each other; means for feeding liquid to said spray heads; and drive means for rotating said spray heads about said center of said rinse vessel and said spray heads rotating in respective parallel planes with respect to which said support plane is inclined.
Claim 3
Dependent Claim
16 words
An apparatus according to claim 1, wherein each of said nozzles is a slit-shaped spray aperture.
Claim 4
Dependent Claim
87 words
An apparatus according to claim 1, further including: a hollow drive shaft rotatably disposed at said center of said rinse vessel, the hollow interior of said drive shaft defining a liquid feed path; a feed path forming member secured to said drive shaft; a mounting member fixedly connected with said feed path forming member; and liquid feed tubes fixedly mounted on said mounting member and extending toward said outer wall of said rinse vessel, said spray heads being disposed on respective ends of said liquid feed tubes.
Claim 5
Dependent Claim
52 words
