Universal medical gas delivery system

An apparatus for coupling a medical gas utilizing device to a first medical gas source having an output end defining an inner bore and a threaded outer surface, the apparatus comprising:

• a connector having a first end defining a first opening of a first diameter, a second end, and an annular abutment extending from the second end toward the first end and defining a second opening of a second diameter, the connector defining an open cavity region extending from the first opening and surrounded by a side wall with a threaded interior surface adapted to couple with the threaded outer surface of the output end of the first medical gas source;
• and
• a bushing being insertable into the connector and having an input end configured to be at least partially received into the inner bore of the output end of the first medical gas source when the threaded interior surface of the connector is coupled with the threaded outer surface of the output end of the first medical gas source, the bushing further including a first annular flange having a diameter less than the first diameter of the first opening and greater than the second diameter of the second opening and configured to reside within the open cavity region of the connector, where the input end of the bushing is configured to be at least partially received within the inner bore of the output end of the first medical gas source when the bushing engages against the output end of the first medical gas source to provide an airtight coupling when the threaded interior surface of the connector is coupled with the threaded outer surface of the output end of the first medical gas source, and the connector being rotatable about the bushing, and
• the bushing includes a bore that is directed entirely through the bushing along a longitudinal axis of the bushing, and
• an end of the bushing opposite the input end is configured to be directly connected to a flexible medical gas tube.

• wherein the annular abutment of the connector includes one or more recesses to allow the connector to be pushed over the annular flange of the bushing,
• the bushing includes a bore that is directed entirely through the bushing along a longitudinal axis of the bushing, and
• an end of the bushing opposite the input end is configured to be directly connected to a flexible medical gas tube.

A gas delivery system comprising:

• a connector including a bore that defines a first opening and a second opening opposite the first opening;
• a bushing positioned within the bore, the bushing including a first flange that is positioned within the bore of the connector, the first flange being configured to engage with the connector to prevent the bushing from being separated from the connector,
• the connector is configured to threadingly engage an output end of a medical gas source at the bore of the connector,
• the connector is configured to rotate about the bushing while the connector is simultaneously blocked from sliding upwardly or downwardly along a longitudinal axis of the bushing to threadingly engage the output end of the medical gas source,
• the bushing includes a second flange positioned outside of the bore of the connector, the second flange being configured to contact the connector, and
• wherein the first flange contacts the connector while the second flange contacts the connector to simultaneously block the connector from sliding upwardly and downwardly along the longitudinal axis of the bushing.
