Abstract:
1. An insufflating system adapted to be in fluid communication with a source of a distending media and an endoscopic device so as to deliver the distending media to the endoscopic device, the insufflating system comprising: a controller for detecting a pressure level within a lumen of the endoscopic device; and a valve assembly in communication with said controller and in fluid communication between the source of distending media and the endoscopic device for delivering the distending media to the endoscopic device and adjusting a flow rate of the distending media delivered to the endoscopic device in response to the detected pressure level and at least one predetermined pressure threshold so as to prevent excess supply and waste of the distending media, wherein the at least one pressure threshold comprises a low pressure transition point and a high pressure transition point, wherein said controller is adapted to automatically control said valve assembly to increase the flow rate from a sensing flow rate to an insufflating flow rate for directing distending media into an anatomical cavity with the endoscopic device if the detected pressure level rises above the low pressure transition point, and wherein said controller is further adapted to automatically control said valve assembly to decrease the flow rate from the insufflating flow rate to a sensing flow rate if the detected pressure level falls below the high pressure transition point resulting from venting distending media to atmosphere with the endoscopic device.
