Abstract
Abstract A rapid connector for use between an endoscope and a camera in which a base ring is connectible to a lens mount of the camera and to an ocular cone of the endoscope and comprises a delimiting glass pane with there being an enclosed space between the delimiting glass pane and a glass pane of the endoscope, and in which the enclosed space is placed in communication with a compressed air source via a radial bore in the base ring and a connector tube therein, and with the ambient atmosphere via an oppositely situated radial bore as well as a hole of the base ring.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
130 words
In a rapid connector for use between an endoscope and a camera, said connector having a base ring connectible to a lens mount of the camera and releasably connectible to an ocular cone of the endoscope, said base ring comprising a delimiting glass pane with means defining an enclosed space between said glass pane and a glass pane delimiting the ocular cone of the endoscope, the improvement comprising means for connecting the enclosed space with a compressed air source, including means defining a first radial passage in the base ring and a connector tube in communication with said first radial passage, and means for connecting the enclosed space with the ambient atmosphere including means defining a second radial passage in said base ring, which is opposite said first radial passage.
Claim 2
Dependent Claim
