This application is a continuation of U.S. application Ser. No. 12/845,475, filed Jul. 28, 2010, which is a continuation of U.S. application Ser. No. 11/257,229, filed Oct. 24, 2005, now U.S. Pat. No. 7,806,850 issued Oct. 5, 2010, each of which is incorporated by reference herein in its entirety.
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; and
a user interface, in communication with said controller and said valve assembly, for receiving a user input;
wherein the endoscopic device comprises a control portion operable by a user and configured to enable distending media to be sent through an insufflating flow pathway in response to a first user action via the control portion and further configured to enable distending media to be sent through a sensing flow pathway in response to a second user action via the control portion, wherein the insufflating flow pathway directs distending media from the source of distending media into an anatomical cavity, and wherein the sensing flow pathway directs distending media from the source of distending media to atmosphere,
wherein said controller is adapted to control said valve assembly to increase the flow rate to an insufflating flow rate in response to the first user action selecting the insufflating flow pathway, and wherein said controller is further adapted to control said valve assembly to decrease the flow rate to a sensing flow rate in response to the second user action selecting the sensing flow pathway;
wherein the first user action and the second user action are switchable with each other; and
wherein the user input comprises at least a first pressure threshold and a second pressure threshold, wherein the first pressure threshold comprises a low pressure transition point and the second pressure threshold comprises a high pressure transition point,
further wherein said controller is adapted to control said valve assembly to increase the flow rate from a sensing flow rate to an insufflating flow rate if the detected pressure rises above the low pressure transition point and wherein said controller is further adapted to control said valve assembly to decrease the flow rate from the insufflating flow rate to the sensing flow rate if the detected pressure falls below the high pressure transition point.
2. An insufflating system according to claim 1, further comprising a disposable tubing set in fluid communication between an output of said valve assembly and a lumen of the endoscopic device.
4. An insufflating system according to claim 1, wherein the user interface comprises a display for displaying data selected from the group consisting of:
5. An insufflating system according to claim 1, wherein the insufflating flow rate is between about 1 and 20 liters per minute, and wherein the sensing flow rate is between about 0.05 and 0.5 liters per minute.
6. An insufflating system according to claim 1, wherein said controller comprises a pressure transducer.
7. An insufflating system according to claim 1, wherein said valve assembly comprises an electro-pneumatic valve.
8. An insufflating system according to claim 1, wherein the distending media is selected from the group consisting of:
9. An insufflating system of claim 4, wherein said controller is adapted to control said valve assembly to increase the flow rate to an insufflating flow rate if the detected pressure level is greater than the first pressure threshold, and wherein said controller is further adapted to automatically control said valve assembly to decrease the flow rate to a sensing flow rate if the detected pressure level is less than the second pressure threshold.
10. A method for delivering distending media to an endoscopic device in fluid communication with a source of a distending media, the method comprising:
delivering the distending media to the endoscopic device;
adjusting a flow rate of the distending media delivered to the endoscopic device in response to an on-demand user action so as to prevent excess supply and waste of the distending media, wherein the adjusting step further comprises:
receiving a first on-demand user action enabling distending media to be sent through an insufflating flow pathway, wherein the insufflating flow pathway directs distending media from the source of distending media into an anatomical cavity,
increasing the flow rate to an insufflating flow rate in response to receipt of the first on-demand user action enabling distending media to be sent through the insufflating flow pathway;
receiving a second on-demand user action enabling distending media to be sent through a sensing flow pathway, wherein the sensing flow pathway directs distending media from the source of distending media to atmosphere; and
decreasing the flow rate to a sensing flow rate in response to receipt of the second on-demand user action enabling distending media to be sent through the sensing flow pathway;
wherein the first on-demand user action and the second on-demand user action are switchable with each other;
receiving a user input for controlling the adjusting step, wherein the user input comprises a first pressure threshold and a second pressure threshold; and
wherein the first pressure threshold comprises a low pressure transition point and the second pressure threshold comprises a high pressure transition point, and wherein the adjusting step comprises adjusting a flow rate of the distending media in response to the low pressure transition point and the high pressure transition point, and
11. A method according to claim 10, further comprising filtering a fluid pathway between the source and the endoscopic device so as to prevent passage of a pathogen from the endoscopic device to the source of the distending media.
12. A method according to claim 10, wherein the insufflating flow rate is between about 1 and 20 liters per minute, and wherein the sensing flow rate is between about 0.05 and 0.5 liters per minute.
13. A method according to claim 10, wherein the adjusting step further comprises:
increasing the flow rate to an insufflating flow rate if the detected pressure is greater than the first pressure threshold; and
decreasing the flow rate to a sensing flow rate if the detected pressure is less than the second pressure threshold.
