Abstract
Abstract A modular medical gas services unit with multiple medical gas outlets supported at the same level on the column. The unit preferably comprises a hollow column with an internal space for housing the gas conduits and power lines. The medical gas supply outlets are mounted so that their longitudinal axes extend radially from the vertical axis of the frame, and the longitudinal axes of adjacent outlets intersect to form an acute angle. In this way, the horizontal dimensions of the column can be minimized while the number of medical gas outlets at the desired height is maximized. In one embodiment, the column is pentagonal in cross-section providing five planar support surfaces for five medical gas outlets. In another embodiment, a square column is equipped with angled outlet panels, each supporting two medical gas outlets. Thus, though the frame is four-sided, as many as eight medical gas outlets can be mounted at the same height on the frame.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
150 words
A modular medical gas services unit comprising: a vertical frame defining a plurality of planar external support surfaces and an internal space; at least one angled medical gas outlet panel superimposed on at least two of the plurality of external support surfaces, each of the angled outlet panels having first and second planar outlet support surfaces, which outlet support surfaces are adjacent and define planes which intersect to form an angle; and a medical gas supply assembly supported in each of the first and second planar outlet support surfaces on each of the at least two angled medical gas outlet panels, each said medical gas supply assembly including: an outlet housing supported in each of the planar outlet support surfaces, the housing having a first end with an exposed outlet and a second end extending through the underlying planar external support surface and into the internal space of the frame.
Claim 2
Dependent Claim
150 words
A modular medical gas services unit comprising: a vertical frame defining a plurality of planar external support surfaces and an internal space; at least one angled medical gas outlet panel superimposed on at least two of the plurality of external support surfaces, each of the angled outlet panels having first and second planar outlet support surfaces, which outlet support surfaces are adjacent and define planes which intersect to form an angle; and a medical gas supply assembly supported in each of the first and second planar outlet support surfaces on each of the at least two angled medical gas outlet panels, each said medical gas supply assembly including: an outlet housing supported in each of the planar outlet support surfaces, the housing having a first end with an exposed outlet and a second end extending through the underlying planar external support surface and into the internal space of the frame.
Claim 3
Dependent Claim
63 words
The modular medical gas services unit of claim 1 comprising four external support surfaces, forming a unit which is substantially square in cross-section, wherein at least one angled medical gas outlet panel is supported on each of the four external support surfaces, all at about the same height, and further comprising a medical gas supply assembly supported in each angled medical gas outlet.
Claim 4
Dependent Claim
32 words
The modular medical gas services unit of claim 1 wherein the angle formed by the intersecting planes defined by the first and second planar outlet support surfaces is at least 90 degrees.
Claim 5
Dependent Claim
31 words
The modular medical gas services unit of claim 3 wherein the angle formed by the intersecting planes defined by the first and second planar outlet support surfaces is an obtuse angle.
Claim 6
Dependent Claim
35 words
The modular medical gas services unit of claim 4 wherein the angle formed by the intersecting planes defined by the first and second planar outlet support surfaces is between about 120 and about 150 degrees.
Claim 7
Dependent Claim
31 words
The modular medical gas services unit of claim 5 wherein the angle formed by the intersecting planes defined by the first and second planar outlet support surfaces is about 135 degrees.
Claim 8
Dependent Claim
56 words
The modular medical gas services unit of claim 1 wherein the medical gas supply assembly further comprises a gas conduit in the internal space of the frame, the gas conduit having a first end connected to the second end of the outlet housing and a second end adapted to be connected to a medical gas supply.
Claim 9
Dependent Claim
22 words
The modular medical gas services unit of claim 1 wherein the frame defines a hollow tubular structure which encloses the internal space.
