Automated control of irrigation and aspiration in a single-use endoscope
First Claim
1. A system for automatically controlling the delivery of insufflation gas, the system comprising:
- a control cabinet including a processor and one or more valves configured to control the delivery of insufflation gas to a patient; and
an endoscope removably connected to the control cabinet and including a pressure sensor and an image sensor at a distal end of the endoscope;
wherein the processor is configured to obtain image signals from the image sensor and pressure readings from the pressure sensor and automatically control insufflation gas delivered to the patient as a function of the image signals and the pressure readings.

Abstract
The present invention is an integrated and automated irrigation and aspiration system for use in an endoscopic imaging system. The system provides for the automated cleaning of poorly prepared patients during a colonoscopy procedure as well as automated cleaning of an imaging system of an endoscope. The invention analyzes images obtained from an image sensor to detect the presence of an obstructed field of view, whereupon a wash routine is initiated to remove the obstruction. The wash routine may be adjusted in accordance with environmental conditions within the patient that are sensed by one or more sensors within the endoscope. In another embodiment, insufflation is automatically controlled to inflate a patient'"'"'s colon as a function of one or more sensor readings obtained from one or more environmental sensor(s) on the endoscope.
