Patent ID: 8585646

Claim:
A method to vent gas from a body cavity during an endoscopic procedure, comprising: connecting a first conduit in fluid communication, either directly or indirectly, with the body cavity to an exhaust gas inlet of a vacuum break device, the vacuum break device comprising: a chamber, the chamber being both in fluid communication with the exhaust gas inlet and in fluid communication with an exhaust gas outlet, a first valve, wherein the chamber further comprises at least one opening in fluid communication with both the chamber and the atmospheric air where the endoscopic procedure is taking place and wherein the first valve is operable to at least partially obstruct the at least one opening resulting in an increase in gas flow rate within the first conduit due to increased vacuum pressure within the chamber; and connecting a second conduit in fluid communication with the exhaust gas outlet directly or indirectly to a suction source; and activating the suction source.
