Gas regulator, control interface module, and methods for surgical applications

摘要

A regulator for regulating the pressure and flow of gas traveling between a gas inlet and a gas outlet. A first pressure regulator in fluid communication with the gas inlet and configured to prevent gas flowing downstream of the first pressure regulator from exceeding a first pressure. A first line between the first pressure regulator and the gas outlet. A second pressure reducing device in fluid communication with the first line downstream of the first pressure regulator and configured to prevent gas flowing in the first line at a point downstream of the second pressure regulator from exceeding a second pressure. A control valve actuatable to an open position when gas is transmitted to a first pilot valve at or below the second pressure, the first pilot valve in fluid communication with the first line.
