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.
Description




FIELD OF THE INVENTION




The present invention relates generally to modular medical gas services units.




SUMMARY OF THE INVENTION




The present invention is directed to a medical gas services unit for use in a medical facility having a floor and a ceiling. The unit comprises a hollow column formed of at least five planar side panels. All of the side panels are vertical and have the same width. Each of the side panels is immediately adjacent two other of the five side panels. A medical gas supply assembly is supported on each of the five side panels, and each of the medical gas supply assemblies is supported at the same height on the column. The height at which the medical gas supply assemblies are supported on the column is between about 40 inches to about 60 inches above the floor. Finally, the width of each of the side panels is only slightly wider than the width of the medical gas supply assembly mounted therein.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




In health care facilities such as hospitals, clinics and convalescent centers, it is essential that medical gas services, such as vacuum, compressed air and oxygen, be immediately available in the event of a medical emergency. Modular units for supplying medical gas services have virtually supplanted the use of individual medical gas systems, such as oxygen tanks and suction machines. Although modular units eliminate the need for multiple pieces of independent equipment at the bedside, the modular unit itself can become an obstacle which interferes with medical care. In critical care units and emergency rooms, multiple medical practitioners must be able to work at the bedside at the same time. Also, the patient must be accessible from virtually every position around the bed, from the head, the foot and the length of both sides. The present invention provides a modular medical gas services unit in the form of a narrow tower or column which is accessible from all sides and occupies little space.




Most modular units provide multiple outlets for medical gases, as well as electrical outlets, telephone outlets, clocks and other services. Although electrical outlets, for example, can be placed in a wide range of locations—i.e., high and low—, the outlets for medical gases must be placed at a convenient height. This is because when the medical gas operating equipment is in use, the function of the equipment must be monitored visually and the controls must be within an arm's reach. For example, medical personnel must be able to visually confirm the flow rate of an oxygen flow meter as well as to quickly adjust it. Thus, the desired level for supporting medical gas outlets usually is between about 40 inches and about 60 inches from the floor.




The operating devices for medical gases, such as vacuum control units and collections containers, as well as oxygen flow meters and humidification containers, are large and substantially wider than the medical gas outlet to which they are connected. Thus, the number of gas outlets which can used at the same time is limited vertically and horizontally by the space needed to accommodate the dimensions of the operating equipment. Because of the height limitations (40″-60″), it is usually undesirable to mount two pieces of equipment vertically. Thus, there is a need to provide as many medical gas outlets as possible at the same height but in a confined space. The modular medical gas services column of this invention is provided with multiple medical gas outlets at the same height, and the outlets are spaced a sufficient distance apart to accommodate a wide range of conventional operating equipment.




The Embodiment of FIG.


1


-


5






With reference now to the drawings in general and to

FIG. 1

in particular, there is shown therein a modular medical gas services column in accordance with the present invention. The column, designated generally by the reference numeral


10


, comprises a narrow vertical frame


12


.




In most instances the frame


12


will be sized for placement between the floor and ceiling of a medical facility. Thus, the column


10


may be equipped with brackets


15


and feet


16


by which the frame


12


is anchored in the selected location.




The frame


12


may be conveniently formed by vertical corner members


14


joined by multiple cross members (not shown). The frame


12


defines an external support surface


20


. As seen in the embodiment of

FIGS. 1-5

, the external support surface


20


is formed of at least one planar surface and preferably four planar surfaces, such as the side panels


22


,


24


,


26


and


28


. The side panels


22


,


24


,


26


and


28


are connected in some suitable manner to the vertical corner members


14


or the internal cross members or both to form a column which is square in cross-section. See

FIGS. 2 and 3

. Thus, in the preferred embodiment shown in

FIGS. 1-5

, the external support surface


20


forms a hollow tubular structure so that the surface


20


encloses an internal space


30


.




As seen in

FIGS. 1 and 3

, at least two medical gas supply assemblies


34


are mounted on the surface


20


. Even more preferably, eight medical gas supply assemblies


34


are supported on the surface


20


around the frame


12


and preferably all at about the same height on the frame


12


. As previously indicated, the desired height usually will be between about 40 inches and about 60 inches from the floor (not shown).




Referring to

FIG. 3

, the medical gas supply assembly


34


includes an outlet housing


36


having a first end


38


and a second end


40


. An outlet


42


(see also

FIG. 1

) is supported on the first end


38


so that it is accessible from near the column


10


. The second end


40


extends into the internal space


30


of the frame


12


. In most instances, the medical gas supply assembly will include a gas conduit


44


(see FIG.


5


). The conduit


44


has a first end


46


(

FIG. 3

) connected to the second end


40


of the medical gas outlet housing


36


and a second end


48


adapted to be connected to a medical gas supply. However, in some cases, the conduit may be attached during installation of the column


10


on site.




With continuing reference to

FIGS. 1 and 3

, the width of each of the side panels


22


,


24


,


26


and


28


is only slightly wider than a conventional medical gas outlet. Thus, using conventional components, only four medical gas outlets could be mounted at the same level on a column this narrow.




However, the number of gas supply assemblies


34


which can be mounted on this narrow, four-sided column


10


is doubled by employing an angled outlet panel


50


. At least one angled outlet panel


50


may be provided on each side panel


22


,


24


,


26


and


28


.




The angled outlet panel


50


comprises generally an angled support bracket


51


by which the medical gas supply assembly is mounted to the frame


12


by screws or some suitable means (not shown). A molded trim cover


52


is attached over the bracket


51


. In the embodiment shown, the bracket


51


and cover


52


are as wide as the side panel


22


. Thus, the side panel


22


is divided into an upper and lower section, and the outlet panel


50


is mounted between the sections. In some embodiments, however, the side panels may be formed of a single section.




Both the bracket


51


and the trim cover are formed into angles, thus defining first and second planar outlet support surfaces


54


and


56


. The first and second planar outlet support surfaces are adjacent and angled relative to each other. Thus, the planes defined by each surface


54


and


56


intersect to form an angle “A,” as illustrated in FIG.


3


. Preferably, the angle A is at least 90 degrees, more preferably, angle A is an obtuse angle, and most preferably, angle A is about 135 degrees.




Now a major advantage of the angled medical gas outlet panel of the present invention will be apparent. As best seen in

FIGS. 4 and 5

, the use of the angled outlet panels


50


permits closer placement of two pieces of medical gas services operating equipment than is possible with two conventional planar outlet panels placed side by side. For example, the two adjacent vacuum control boxes with depending containers


60


and


62


could not be supported so closely together if connected to two medical gas outlets mounted flush in the side panel


24


. For a side-by-side, flush-mounted arrangement, the width of the side panel


24


would have to be increased. This would, in turn, increase the overall size of the column


10


which is contrary to the goal of reducing space requirements in medical gas services modules.




Yet, as shown in

FIGS. 1 and 4

, even with the minimal overall size of the column


10


of this invention, there is ample room internally and externally for numerous other service outlets and attachment devices. For example, electrical outlets


70


can be positioned at various heights. Telephone jacks


72


and display panels for digital clocks and timers


74


can be conveniently placed along the vertical length of the side panels


22


,


24


,


26


and


28


. Still further, the vertical corner members


14


may be formed to provide equipment mounting tracks


76


, and additional equipment mounting tracks


78


can be mounted on the side panels. In this way, bracket devices permit the adjustable attachment of a wide variety of other equipment.




The Embodiment of FIG.


6


-


9






Turning now to

FIGS. 6-9

, a second embodiment of the present invention will be described. Illustrated in

FIG. 6

is a modular medical gas services column


100


comprising a vertical frame


102


. As best seen in

FIG. 7

, a preferred frame


102


comprises a plurality of vertical members


103


which are connected by internal cross members (not shown). Thus, the frame


102


forms a hollow tubular structure having an external support surface


104


which encloses an internal space


106


. Although the external support surface


104


may take several forms, a preferred configuration comprises five planar side panels


110


,


112


,


114


,


116


and


118


of equal width.




In the preferred construction, the width of each side panel is only sightly greater than the width of a conventional medical gas service outlet. In this way, a medical gas outlet may be placed on each side panel


110


,


112


,


114


,


116


and


118


at about the same height.




To that end, the column


100


comprises at least two medical gas supply assemblies, one of which is designated by the reference numeral


120


. As shown in

FIG. 8

, the medical gas supply assembly


120


comprises generally an outlet housing


122


mounted on a bracket


123


which is attached to the vertical members


103


of the frame


102


.




The outlet housing


122


has a first end


124


supporting the exposed outlet


125


and a second end


126


which extends into the internal space


106


. A window


127


is cut in the side panel


118


to expose the outlet


125


. The second end


126


of the outlet housing


122


is adapted to be connected to a gas conduit


130


which is contained in the internal space


106


. As best seen in

FIG. 9

, the is other end


132


of the gas conduit


130


is adapted to be connected to a medical gas supply (not shown).




Returning to

FIG. 8

, it now will be understood that the longitudinal axis of each of the medical gas supply assemblies


120


extends generally radially from the center of the internal space


106


or the longitudinal axis of the frame


102


. Thus, the intersection of the longitudinal axes of any two adjacent outlet housings


120


forms an acute angle, designated herein as “B.” The acuity of angle B will vary depending on the number of medical gas supply assemblies mounted around the frame. In the pentagonal configuration shown, angle B is about 72 degrees.




Turning once more to

FIG. 9

, the advantage of the present invention is illustrated further. With the medical gas supply assemblies


120


mounted radially at acute angles to each other, the number of medical gas service operating devices


134


which can be used simultaneously is increased without increasing the overall dimensions of the column


100


.




Referring again to

FIGS. 1-5

, and particularly to

FIG. 3

, it will be appreciated that the medical gas supply assemblies


34


in the first embodiment using the angled outlet panels


50


also are arranged radially so that the longitudinal axes of adjacent outlet housings


36


intersect to form acute angles. However, in the first described embodiment, the distance between the outlets is not equal; outlets in the same outlet panel


50


are closer than outlets in adjacent outlet panels. Similarly, although the angle formed by the longitudinal axes of any two adjacent outlet housings is acute, the angles are not all the same; for example, the axes of outlet housings


34


in the same outlet panel


50


is about 40 degrees, while the angle between outlet housings in adjacent outlet panels is about 50 degrees.




It will also be appreciated that the longitudinal axes of the outlet housings


36


, as shown in

FIG. 3

, do not extend radially precisely from the center of the internal space


30


of the longitudinal axis of the frame


12


. Nevertheless, for purposes of this invention, the expression “generally radially” is intended to include such a slightly offset arrangement as is found in the embodiment of

FIGS. 1-5

.




Changes may be made in the combination and arrangement of the various parts, elements, steps and procedures described herein without departing from the spirit and scope of the invention as defined in the following claims.
