OXYGEN BOTTLE CARRIER PARTICULARLY FOR STRETCHERS
Abstract
An oxygen bottle carrier, particularly for ambulance stretchers,
is adapted to be mounted on the framework of the stretcher beneath
the head by adjustable brackets, the adjustability of the brackets
facilitating use of the bottle carrier with different sized
stretchers. The bottle is inserted and replaced through an open end
of the cradle structure of the carrier, and a trigger controlled
latch normally prevents removal of the bottle, while permitting
protrusion of the bottle neck and associated gauges and regulators.
The carrier, including a bottle carried therein, lies substantially
within the boundaries of the stretcher in unused space beneath the
head, thus being out of the way while still readily accessible.

Description
FIELD OF THE INVENTION
This invention relates to a bottle carrier attachment for a
conveyance, and particularly to an oxygen bottle carrier attachment
for an ambulance stretcher.
BACKGROUND AND SUMMARY OF THE INVENTION
It is quite often necessary for oxygen to be administered to a
patient while he is being conveyed in an ambulance stretcher,
during the time that he is being carried on the stretcher to the
ambulance, while the ambulance is travelling to the hospital or
other emergency facility, and while the patient is being removed
from the ambulance on the stretcher at the hospital or other
emergency facility. To my knowledge, both in the past and at
present, it generally is the practice to either place the oxygen
bottle on the stretcher with the patient, or to have it carried by
an extra attendant accompanying the stretcher bearers. Particularly
during the time that the stretcher is being removed from a building
to the ambulance, neither method is satisfactory. For instance, an
extra attendant may not always be available. Even when available,
an extra attendant makes for an unwieldy procedure, since
residential doorways, hallways, stairways, etc., were not designed
for the simultaneous passage of a stretcher and a bottle-carrying
attendant. It also is not very satisfactory to place the bottle on
the stretcher with the patient. Despite all its advantages, an
oxygen bottle with associated regulators, gauges, valves, etc., is
not a desirable bedfellow for an emergency patient. Also, when the
bottle is placed on the stretcher with the patient, the stretcher
bearers are often required to do a juggling act to keep one or the
other from falling off the stretcher. Even if the bottle remains on
the stretcher, it may protrude therefrom such that it may be caught
on doorjambs, passageway corners, etc. It has been previously
proposed to provide special bottle carriers for such stretchers,
one such example being disclosed in U.S. Pat. No. 3,427,668, which
discloses a bottle carrier mounted above the stretcher over the
feet of the patient. However, to my knowledge such previously
proposed arrangements have not been adopted to any substantial
extent, if at all. For instance, a bottle carrier at the patient's
feet is rather removed from the scene of the action, and one which
is mounted above the stretcher presents some hindrance to moving
the patient on and off the stretcher, may obstruct the view of the
stretcher bearers, and in general would seem to make the procedure
and the apparatus somewhat unwieldy.
In general, it is the object of this invention to provide a bottle
carrier attachment for a conveyance, particularly an oxygen bottle
carrier attachment for an ambulance stretcher, which carrier
attachment is characterized by its advantageous location, its ease
of mounting, its adaptability for stretchers of different sizes as
well as bottles of different sizes, and the ease with which a
bottle may be removed or inserted. Thus, my carrier attachment is
mounted on the stretcher in an out-of-the-way location, but is
still readily accessible, and the gauges are readily visible. It
locates the oxygen bottle where it is needed, that is, close to the
patient's head. It utilizes unused space substantially within the
lateral bounds of the stretcher, which space would otherwise be
wasted. It does not contribute to top-heaviness of the stretcher.
It is easily mounted on the stretcher, and is adjustable for
stretchers of differnet sizes. It is usable with most standard
sizes for oxygen bottles, and facilitates quick removal and
replacement of an exhausted oxygen bottle. Toward achieving such
advantageous characteristics, I have provided a carrier attachment
which mounts to the U-shaped framework of the stretcher beneath the
head of the stretcher, in the unused space forward of the stretcher
wheels or casters, and beneath the area encompassed by the forward
portion of the stretcher framework. The carrier is oriented
transversely of the stretcher in this space such that the oxygen
gauges of the bottle are located so as to be easily visible to the
attendant at the forward end of the stretcher. My carrier
attachment incorporates adjustable mounting brackets which, when
mounted, preferably lie in the plane of the tubular framework of
the stretcher, closely adjacent to but below the plane of the
patient supporting surface. The carrier attachment includes a
cradle-like structure for supporting bottles of current standard
sizes, and the bottle is retained in the cradle by a bottle latch
which permits only the neck portion of the bottle, with its
associated gauges, etc., to protrude. The latch is readily released
by a trigger-like mechanism located beneath the stretcher, but in
the area of a side edge so as to be readily actuatable when
replacing the bottle. In addition to its functional advantages, my
carrier attachment also lends itself to economical manufacture, and
is of simple but sturdy and reliable construction.
Other and further advantages and features of the invention will
become apparent to those skilled in the art from the ensuing
description of a preferred embodiment of the invention, taken in
conjunction with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring first to FIG. 1, a conventional ambulance stretcher 1
comprises a basic tubular framework 3 which normally extends in a
closed rectangular configuration. Mounted on the framework 3 is a
patient supporting surface 5 which conventionally comprises a
mattress or the like supported on a planar framework, which in turn
is supported on the tubular framework 3. Side rails 2 and 4 are
conventional. The planar surface on which the mattress 5 or the
like is supported may comprise tubular lattice work supporting a
table-like surface, and usually there is a space between this
surface and the end members of the tubular framework 3, as
illustrated generally in FIG. 1. Also, this conventional
construction normally incorporates an extensible and retractable
wheel or caster structure supported by the tubular framework 3
beneath the stretcher, the wheels or casters being located normally
somewhat inwardly from the ends of the stretcher, in both the
extended or retracted positions, corresponding, respectively, to
the raised or lowered positions of the stretcher. Illustrated
generally at 6 is my oxygen bottle carrier attachment, with a
standard oxygen bottle 7 mounted therein, and with conventional
gauges, regulators, valving, connected to the neck of the bottle,
as shown generally at 8. It will be noted from FIG. 1 that the
carrier attachment is located beneath the head of the stretcher in
a position forward of the front wheels or casters (not shown) of
the stretcher. The attachment lies substantially within the lateral
boundaries of the stretcher, and is so located that the gauges 8
also will lie substantially within these lateral boundaries,
preferably closely adjacent the forward left hand corner so as to
be easily visible by the forward stretcher bearer.
Referring now to FIG. 2, only the forward U-shaped tubular
framework 3 of the stretcher is illustrated for purposes of
clarity. The carrier attachment 6 comprises basically a cradle-like
structure for holding the bottle 7, and a plurality of brackets for
mounting this cradle-like structure to the tubular framework 3. As
illustrated also in FIG. 3, the cradle structure is formed by
spaced U-shaped metal members 9 and 10 which are connected by metal
rods 12 to form a bottle holder. One of the rods 12 includes a
section 12c which closes one end of the cradle, the other end being
open. U-shaped members 9 and 10 are connected at their upper ends
by metal members 11 and 17 welded to the legs of members 9 and 10
adjacent their upper ends. As illustrated best in FIGS. 3 and 1,
two of the metal rods 12 are extended to form a support portion 12b
for the gauges and valving 8 of the oxygen bottle. The gauge and
valve assembly of the bottle will rest on this support portion 12b,
so as to maintain the gauges in a readable orientation as shown in
FIG. 1.
The cradle structure is fixed to the side legs of the U-shaped
framework 3 by brackets 13 and 18, of which bracket 18 is welded to
U-shaped member 10, and bracket 13 is adjustably coupled to
U-shaped member 9 through a slot 14 and bolt and wing nut assembly
16. Bracket 13 includes a deformed end portion 15 having a slot 15a
formed therein to mate with and slide along guide rod 12a. Brackets
13 and 18 are formed at their outer ends 13a and 18a with
concavities corresponding to the curvature of tubular framework 3.
By loosening wing nut 16, bracket 13 can be adjusted inwardly,
concavity 18a of bracket 18 then placed against tubular framework 3
as shown in FIG. 2, and bracket 13 then moved outwardly until its
concavity 13a bears against tubular framework 3, and wing nut 16
then tightened, such that the assembly in essence is wedged between
the two legs of the tubular framework 3 to provide a measure of
support. The assembly is further supported within the framework by
adjustable brackets 19 and 22, which are formed with U-shaped
portions 21 and 24 at their outer ends. Brackets 19 and 22 extend
through slots 9a and 10a, respectively, of members 9 and 10, and
are adjustably coupled to the assembly by bolt and wing nut
assemblies 20 and 23 which pass through adjustment slots 11a and
17a in cross members 11 and 17, respectively. Thus, bracket members
19 and 22 are adjustable transversely relative to the longitudinal
axis of the assembly, and encompass the bottom leg of the U-shaped
framework 3 by their end portions 21 and 24. Although not
necessary, bolt holes 40 can be formed in the upper and lower legs
of the U-shaped outer portions 21 and 24 of brackets 19 and 22 so
that bolts can be passed therethrough to positively lock brackets
19 and 22 to the tubular framework.
A bottle latch member 25 is pivotally coupled to U-shaped member 10
by bolts 28 and 29, and includes a concave formation 26 for bearing
against the reduced end portion adjacent the neck of an oxygen
bottle so as to releasably lock the bottle in the cradle structure.
A tension spring 27 extends between cross member 17 and an extended
leg of latch member 25 so as to pivotally bias the latch member
into its locking or latching position. A latch trigger 30 is
pivotally coupled to bracket 18 by bolts 31, and is coupled at its
inner end to the extended leg of latch member 25, such that when
trigger 30 is pulled upwardly by its protruding handle portion, the
inner portion will move the extended leg of latch member 25
downwardly, thus moving latch member 25 and its concave portion 26
upwardly to unlatch the bottle, and permit removal thereof. Since
latch member 25 and trigger 30 pivot about different centers, the
opening in trigger 30 through which bolt 32 passes is made oblong
so as to permit the necessary movement of bolt 32 within the oblong
opening of trigger 30 during pivotal movement thereof. If desired,
suitable abutments or stops can be provided on member 10 to define
the limits of pivotal movement of latch member 25, and spacers or
the like can be placed on bolt 32 between trigger 30 and latch
member 25.
It will be apparent from the foregoing that the carrier attachment
can be mounted to the framework of a stretcher merely by adjusting
three brackets, and tightening three bolts, or five bolts if bolts
are provided through bolt holes 40 of brackets 19 and 22. These
brackets mount the attachment very rigidly on the tubular
framework, and since none of the assembly extends substantially
above the plane of the tubular framework, the assembly may extend
for a substantial distance under the patient supporting surface if
desired. Normally the attachment will be positioned closely
adjacent the head end of the stretcher so as to facilitate ready
visibility of the gauges of the oxygen bottle.
It will be understood that the preferred embodiment which has been
illustrated and described herein is susceptible of various
modifications without departing from the scope and spirit of the
invention. Therefore, the preferred embodiment is to be considered
as exemplary of the invention, and not limiting.
Having thus described and illustrated a preferred embodiment of my
invention in the manner required by the statutes,
