WHIRLPOOL BATH FOR LIMB EXTREMITIES
Abstract
A lightweight, portable container having a perforated tube
incorporated in the wall of the container along a substantial
length of the wall from adjacent the top to the bottom thereof, for
injecting air into water contained in the container, causing a
circulation of the water for hydro treatment. The container is of a
size to admit the extremities of a user's limb which may be
immersed in the circulating water for its therapeutic effects. The
water may be heated by an electrical heater coil in the container
or by circulating heated air through the tube.

Claims
We claim:
1. A portable whirlpool bath for limb extremities comprising:
a. insulated container means having a top opening and of a size to
admit only limb extremities and being easily portable;
b. perforated tubing mounted in said container from about said top
opening to the bottom of said container, and being formed in a coil
therein;
c. air blower means mounted on the exterior of said container in
communication with said tubing for injecting air through said
perforated tubing;
d. electrical heating coil means mounted internally of said
container, coiled from adjacent the top opening to about the bottom
thereof, and arranged to heat water in said container; and
e. means for actuating said blower means.
2. A portable whirlpool bath according to claim 1, wherein said
container insulation is foamed synthetic plastic resin having
resistant surfaces covering the same.
Description
In certain pathological conditions of limb extremities,
hydro-treatment has been found helpful. Such treatment involves
immersing the affected limb in gently circulating heated water.
Available units for hydrotherapy are expensive, large and therefore
not too portable, and are the currently not available in the
patient's home. While portable water circulators have been provided
in the past, they are arranged to be attached to a bathtub or the
like, which of course limits the use of such a unit. Additionally,
persons who are required to stand during their employment for long
periods of time usually acquire pathological conditions of the
lower limbs, and hydrotherapy has been found quite effective in
such cases. Salespersons, for example, are subject to such
infirmities of the lower limbs, particularly salespersons who stand
behind counters. Many of such sales people can not afford the
treatment or the currently available devices for the treatment.
It is, therefore, an object and advantage of the invention to
provide an inexpensive portable hydrotherapy unit for limb
extremities.
Another object of the invention is to provide an air circulated
water bath for the hydrotherapy of limb extremities.
Still another object of the invention is to provide a heated,
controlled, hydrotherapy unit for lower limb extremities.
Still another object of the invention is to provide a portable,
integral hydrotherapy unit having included water circulated and
heating means.
An additional object of the invention is to provide an inexpensive,
portable hydrotherapy unit useful for user's leg below the knee and
the user's arm.
These and other objects and advantages of the invention may be
readily ascertained by referring to the description and appended
illustrations in which:
FIG. 1 is a perspective view of one form of the invention;
FIG. 2 is a cross sectional view of one form of the invention,
illustrating an air circulating tube as well as an electrical
heater coil;
FIG. 3 is a side elevational view of an additional form of the
invention utilizing heated air for circulating contained water;
and
FIG. 4 is an enlarged detail view of a heater-blower unit for the
device of FIG. 3.
In the device selected for illustration in FIG. 1, a generally
cylindrical container formed of insulated, water proof material
(for example, foam plastic with a resistant sheet on the surfaces
of the container, metal container with an insulating liner of
plastic, or the like) is provided with a bail handle 12 for
portability of the container. A drain valve 14 may be optionally
provided at the bottom of the container for release of contained
fluid. The handle 12 may be a bail type handle (used in ordinary
buckets) or the container may be provided with recessed handles,
finger grips, or the like, for portability of the unit. Tubing 16,
having a plurality of small apertures 18 therein, is coiled around
the wall of the container from adjacent the top to approximately
the bottom of the container. The holes are spaced in the tubing to
provide desired circulation of water when air is forced through the
apertures in the tubing. The tubing may be plastic (synthetic
resins or the like) and may be formed in the wall of the container
(formed of foam plastic, or the like) or it may be merely secured
to the container wall by an adhesive, cement or the like. It is
preferable to use an insulated bucket since the water used for the
hydrotherapy is preferably heated and the insulated bucket prevents
too much heat loss. A control box blower unit 20 with an electrical
lead 22 is provided for the container, which is explained below. A
small blower may be mounted in the control box 20 for forcing air
through the tube 16 causing circulation of air through the tube,
and thereby circulating the water in the container. Heated water
may be placed in the container for the treatment.
In the device illustrated in FIG. 2, a container 30 is provided
with a tubing 32 formed in the wall of the insulated container, and
an electrical heating coil 34 is likewise formed in the wall of the
container, both coiled from about the top to the bottom of the
container. The tubing 32 is provided with small apertures 36 for
introducing air into contained liquid. A control box 38 is provided
with a small blower 40. A seal 42 surrounds the electrical lead to
the heating coil 34. An electrical lead 44, arranged to be attached
to common household outlet, is connected to the heating coil 34 and
the blower 38(connection not shown). The blower and heating coil
may be provided with conventional on-off switches. Additionally,
the heater may be provided with a rheostat for control in a
conventional manner. A thermostat in the container may be added in
conventional manner for additional control of water temperature.
The blower 40 may be a small blower using a fractional horsepower
electrical motor, such as a motor-blower combination found on
portable hair dryers. The blower should provide air less than about
20 pounds per square inch of pressure for producing a satisfactory
whirlpool effect in the water. The coil should be arranged to heat
the water from about 100.degree. to 130.degree. F. so that the
patient may use the unit for hydrotherapy for 15 to 20 minutes.
In using the device of the invention, the container is sufficiently
filled with water (with or without chemicals) to permit the
introduction of a limb into the container. When the container is
filled with ordinary tap water it should be heated to the desired
temperature, or, when using the device such as that shown in FIG. 2
the coil is turned on to provide the temperature desired. The
blower is then turned on and the limb of the user immersed in the
water in the container. The whirlpool effect is achieved by the air
forced through the tubing. By conventional wiring and thermostats
the water may be accurately controlled as to temperature, and the
blower may be controlled to provide a soft or hard whirlpool effect
by controlling the power going to the motor of the blower.
In the device illustrated in FIGS. 3 and 4, a container 10 is
provided with a control box 20 having a heating, air blower 21
mounted therein, in the manner of blower 20. The power line 22 is
provided with a pronged plug 23 for attaching to an electrical
circuit. The container 10 includes the air tube 16 with apertures
18, shown in FIG. 1, however, the blower intake includes resistance
wire coils 25 which are wired into the circuit in conventional
manner, so as to be heated and thereby heat the air passing through
the blower. The arrangement is similar to conventional portable
driers, and similar controls may be included with the unit. The
configuration of the air line in the or attached to the wall of the
container is preferably spiralled down along the inner wall with
the holes in a spiral path so that air exuding from the tube
circulates the water. Other configurations may be made in the hole
pattern including holes from only the bottom of the container,
causing the water to circulate in the container by the introduced
air.
