Claims
I claim:
1. In combination with a hydrotherapy tank having opposite rim
portions, an attachment for suspending a patient within said tank,
comprising:
a pair of crossbars having bearing members at each end thereof
engageable with said rim portions;
means structurally independent of said tank maintaining the spaced
relationship of said crossbars on said rim portions; and
a hammock having the opposite ends thereof respectively engaging
said crossbars for suspension within said tank.
2. A combination as defined in claim 1, wherein said means
maintaining the spaced relationship of said crossbars is at least
one spacing bar interconnecting corresponding end portions
thereof.
3. A combination as defined in claim 2, wherein spacing bars
interconnect both corresponding end portions of said crossbars.
4. A combination as defined in claim 3, wherein said spacing bars
are adjustable with respect to said crossbars to vary the spacing
thereof.
5. A combination as defined in claim 1, wherein said bearing
members are U-shaped, and adapted to hook over said rim portions,
one side of said U-shaped members being engaged with said
crossbars, respectively.
6. A combination as defined in claim 5, wherein said one side of
the U-shaped member is provided with a stud telescopically engaging
the end of said crossbars, respectively.
7. A combination as defined in claim 5, wherein the outer sides of
said U-shaped members on corresponding sides of said tank are
interconnected by spacing bars.
8. A combination as defined in claim 1, wherein said hammock is
substantially wider at one end than at the other.
Description
BACKGROUND OF THE INVENTION
Hydrotherapy is one of the most frequently used procedures in the
general class of treatments commonly known as physical therapy.
According to the usual practices, all or part of a patient is
immersed in a tank of circulating water, with the temperature of
the tank being selected for the particular purposes of the
treatment. Occasionally, some additives are included in the water
for specific purposes. Where it is desirable to treat as much of
the patient as possible, the conventional hydrotherapy tank assumes
the form of a large bathtub equipped with suitable circulating
pumps and supply and drain conduits. In the case of elderly or
incapacitated patients, it is sometimes very difficult to place and
maintain the position of a patient within the tank, and remove him
after the treatment has finished. With the patient wetted over the
major portion of his body, it is very hard to handle him without
slipping or applying excessive pressures that may aggravate his
physical condition. It is also obvious that the area in which the
patient is supported on the bottom of the tank, as in a bathtub, is
not subject to the rapid circulation of the water on which the
principle benefits of the treatment depend.
SUMMARY OF THE INVENTION
The present invention provides for the support of a patient within
a standard hydrotherapy tank through the use of a hammock disposed
within the tank. Preferably, the hammock is supported on a
rack-shaped structure including crossbars and spacing bars, with
the entire structure (including the hammock) being vertically
removable for not only the convenience in assembling the hammock to
the tank, but also for the possible dual sue of the hammock and its
supporting rack as a stretcher in carrying a patient to and from
the tank.
In the preferred form of the invention, the hammock-supporting rack
is defined by a pair of spaced crossbars with end fittings that
engage the rim of the tank on opposite sides. These crossbars are
maintained in spaced relationship by interconnecting bars. The
relationship between the connecting bars and crossbars may be
rendered adjustable for determining the spacing between the ends of
the hammock so that the degree of slack in the hammock can be
altered.
DESCRIPTION OF THE DRAWING
The several features of the invention will be analyzed in detail
through a discussion of the particular embodiments illustrated in
the accompanying drawing. In the drawing:
FIG. 1 is a perspective view of a standard hydrotherapy tank
equipped with the preferred form of the hammock attachment.
FIG. 2 is a sectional elevation on an enlarged scale over that of
FIG. 1 showing the structure at one of the corners of the
hammock-supporting rack.
FIG. 3 is a perspective view of a modified form of the
invention.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIG. 1 and 2, the standard hydrotherapy tank generally
indicated at 10 has the parallel opposite rim portions 11 and 12. A
standard pump unit 13 is normally provided to maintain a
circulation of water or other solution within the tank 10. A rack
structure generally indicated at 14 constitutes an attachment that
can be slipped down onto the tank 10 for the support of the hammock
15 within the tank. This hammock is preferably made of open
netting, and is substantially narrower at the end 16 than at the
opposite end 17 permit the legs of a patient to be disposed on
either side of the end 16. Both of these ends have tubular sections
embracing the crossbars 18 and 19, respectively.
The most convenient and economical structure for the crossbar
assembly is shown in FIG. 2. The bar 19 is tubular, and receives
the stud 20 having the enlarged head 21 welded to the inside leg 22
of the U-shaped bearing member 23 forming one end of the crossbar
assembly. The outer leg 24 is spaced sufficiently from the inner
leg to receive the rim of the tank 10, and these outer legs are
interconnected on corresponding sides of the tank by spacing bars
25 and 26. The function of the spacing bars is to resist the
tendency for weight suspended in hammock 15 to draw the bars 18 and
19 together. The telescopic interengagement between the stud 20 and
the tube 19 will accommodate considerable variation in width
between tanks. This interengagement may be rendered more secure (as
when it becomes desirable to use the entire rack in the manner of a
stretcher) by a conventional cross pin (not shown) or its
equivalent. In either case, the storage of the hammock attachment
is considerably facilitated by the disengageability of the tubes 18
and 19 from the end assemblies.
Where the attachment of the spacing bars 25 and 26 is fixed, as
shown in FIG. 1, the suspended position of the patient within the
tank is controllable by determining various amounts of slack in the
hammock, either through the use of hammocks of varying length, or
through some other form of adjustability of the tubular ends of the
hammock. The assembly at each of the four corners of the attachment
are the same, with the U-shaped members 27--29 being identical to
the member 23 shown in FIG. 2.
It is possible to provide a different form of adjustment for
altering the amount of slack in the hammock 15, and this can be
done through the arrangement shown in FIG. 3. The U-shaped member
30 is provided with a stud similar to the stud 20 shown in FIG. 2.
The spacing bar 31 may be secured to the member 30 by a bolt 32,
which is engageable either in a central hole (as shown in FIG. 3)
or at the holes 33 or 34. The use of the hole 33 will provide more
slack, and the use of the hole 34 will correspondently provide less
slack in the hammock. Some form of turnbuckle connection in the
spacing bars can also be provided to give this same sort of spacing
adjustability. For lightness of weight, it is preferable that the
spacing bars be of tubular configuration, flattened at the ends as
shown in the drawing to facilitate the attachment to the end
portions of the crossbar assemblies. Where there is no concern for
the use of the rack 14 as a separable hammock support, the U-shaped
members may be clamped or bolted to the walls of the tank.
The particular embodiments of the present invention which have been
illustrated and discussed herein are for illustrative purposes only
and are not to be considered as a limitation upon the scope of the
appended claims. In these claims, it is my intent to claim the
entire invention disclosed herein, except as I am limited by the
prior art.
