US Patent 7597662 Multi-fluid delivery system

A proximal connector of an endoscope shaft can be manually attached to and detached from a console, such that the connector and endoscope shaft can be provided as a single use device. An interface between the proximal connector and console can include a sliding plate moveable to operably make and break at least some of the connections between the console and endoscope shaft. A fluid reservoir may be separately connected to the proximal connector and hang from a mount on the interface.
