Patent ID: 7819118

Claim:
A method of upgrading a control panel of a medical gas delivery system comprising an enclosure and a cover operative to close an opening to the enclosure, wherein the enclosure includes therein at least one valve and first and second pipelines in operative connection with each respective end of the at least one valve, wherein the first and second pipelines each include a front facing side which faces the opening to the enclosure, wherein the front facing side of the first pipeline includes a threaded opening therein, wherein a pressure gauge is mounted in the threaded opening: a) removing the pressure gauge from the threaded opening of the first pipeline; b) mounting a fitting to the threaded opening of the first pipeline, wherein the fitting includes a body and a threaded projection extending from the body, wherein the threaded projection is threaded into the threaded opening of the first pipeline, wherein the body includes at least two ports, wherein a first one of the ports includes a gas specific DISS threaded coupler mounted thereto, which extends from the fitting in a direction that is perpendicular to a longitudinal axis of the projection of the fitting, wherein a second one of the ports includes a second pressure gauge which extends from the fitting in a direction that is perpendicular to the longitudinal axis of the projection of the fitting, wherein when mounted to the threaded opening of the first pipeline, the fitting, the gas specific DISS threaded coupler, and the second pressure gauge do not extend through the opening of the enclosure.
