INFLATABLE HAIR WASHING AID
Abstract
A hair washing aid which is comprised of an inflatable ring of
substantial size which is positioned above a bottom member which
spans across the ring. An intermediate ring therebetween defines a
wall immediately above the bottom and the intermediate ring is
perforated at a number of locations to serve as a collecting trough
or gutter for water. The device is preferably used with bed-ridden
patients in hospitals and the like. To maintain the apparatus level
when a patient's head is placed in the ring, an inflatable pillow
is incorporated which can be inflated immediately beneath the neck
of the patient to level the bottom. Water accumulated in the bottom
is drained through an attached down-chute which is of sufficient
length to extend over the side of the bed. The down-chute has a
lower end which is open but which is adapted to be closed by a clip
which serves as a valve.

background of the invention
Various and sundry devices have heretofore been proposed for
capturing water when a bed-ridden person has his hair washed.
Devices of the sort in the prior art patents mentioned above have
been used and found wanting. They attempt to solve the problem of
providing day-to-day cleanliness for the hair of a bed-ridden
patient, but have been found unacceptable in the main.
Some of the problems encountered by the prior art devices include
difficulty in positioning a rigid or near rigid structure beneath
the head of a patient. A rigid container is difficult to work with,
and is often uncomfortable to the patient. Other devices have been
provided which are flexible but which are too expensive to
fabricate and use. Some of the devices of the prior art have been
offered to hospitals and refused because of excessive costs.
SUMMARY OF THE INVENTION
The present invention incorporates a sheet bottom of resilient
material which is attached to a small ring and a larger ring
thereabove. The larger ring is preferably inflated. It defines an
internal volume sufficient to encompass a head and provide working
room therearound. The smaller ring is not inflatable, but pulls to
a generally ring-like construction when the large ring is inflated.
The small ring is perforated at many locations. The perforations
enable the small ring to serve as a gutter or drain for water.
Water is introduced above the bottom and is captured within the
device. Water enters the small ring which then directs surplus
water around to a single side of the bottom where the bottom
extends outwardly into an enclosed chute. The chute is flexible and
may hang across the bed and over the side. It has an open lower end
which is adapted to be pinched off, and is readily positioned above
a bucket or drain. The chute is of substantial length to permit a
good deal of flexibility in the arrangement of the device of the
present invention with regard to the position of the patient and
the bed. An inflatable pillow extends partly about the
circumference of the large ring and is adapted to be positioned
below the neck of the user to provide reinforcement where the
weight of the user tends to distort the bottom from a generally
horizontal plane.
DESCRIPTION OF THE DRAWINGS
FIG. 1 is a top plan view with a portion of the side broken away
illustrating internal details of construction showing the hair
washing device of the present invention; and,
FIG. 2 is a sectional view taken along the line 2 -- 2 of FIG. 1
showing details of construction of the bottom and ring thereabove
which defines a hair washing aid.
DESCRIPTION OF THE PREFERRED EMBODIMENT
In the drawings, the hair washing aid 10 incorporates a large
planar bottom member 12 preferably formed of a resilient material.
A typical polyolefin plastic is suitable for this purpose. For
example, the bottom is formed of a polyolefin material which is
perhaps as much as twenty millinches thick. The bottom 12 is of
substantial diameter, typically in the range of about eighteen
inches for a small version of the device, to about twenty-seven to
thirty inches for a larger version. The bottom 12 is circular at
all points except for a lateral extension 14 which is shown in FIG.
2. The portion 14 has the form of a radially directed tab of
substantial length. It tapers along its length as better
illustrated in FIG. 1. The tab portion 14 extends to a lower end
16. A parallel second tab 18 is positioned immediately above the
tab 14 and the two are joined by a side wall. The upper tab portion
16 can be curved or wrapped around to connect with the lower tab
portion 14 to define a leak-proof chute or conduit. The upper tab
18 extends to the lower end as illustrated in FIG. 2, and defines
the mouth or opening 16. The two tab portions 14 and 18 and the
adjacent side wall portions connected between them serve as a
funnel or conduit for drainage of water. They can be integrally
formed, or can be formed of any number of members with appropriate
seams formed by suitable solvents which join the plastic materials
together.
The bottom member 12 joins to an encircling ringlike member 20
which is preferably rather small, perhaps in the range of about two
inches in diameter, and serving as a collection tube. Several
perforations or openings 22 in the collection tube 20 are just
above the level of the bottom.
In FIG. 1, the collection tube is shown in dotted line partly
interrupted where the tab 14 extends radially outwardly from the
bottom. This enables water collected in the tube to be introduced
into the conduit defined by the tab 14. The collection tube 20 is
interrupted at the tab 14. This enables the water on the bottom to
drain into the conduit. Water has two escape routes. The first is
from the bottom 12 directly into the conduit. The second drainage
route is through the collection tube 20 upon entry at any of the
perforations 22 which are arranged about the perimeter of the
device.
The conduit shown at the right hand side of FIG. 2 has about the
same height as the diameter of the collection tube. This diameter
is maintained more or less uniform about the device although the
weight of the head of a user may deform it somewhat. Resilient
materials are preferably easily deformed.
A collar strip 24 extends about the device attached to the bottom
and attached to the collection tube 20. The collar strip 24
encircles the device and assists in securing the collection tube in
the specified location. The encircling collar 24 is attached to an
inflatable tube 26. The tube 26 is substantially larger than the
tube 20 and is in the approximate range of four to six inches in
diameter, the optimum diameter being about five inches. It is
arranged coincident with the circle of the tube 20 as illustrated
in FIG. 2. The tube 26 is inflatable by means of an inflation tube
or hose 28 shown in FIG. 1. A clamp 30 can be positioned on the
inflation hose to seal air under pressure in the tube 26 after it
has been inflated. The tube 26, upon inflation enlarges and pulls
the collar 24. The pull, coupled with the pulling acting on the
tube 20, tends to erect the tube 20. It is not mandatory that the
tube 20 erect fully so that it describes a circle in cross section.
Rather, it is important that the tube 20 open to an extent
sufficient to allow it to collect water. The tube 26 cooperates
with the collar 24 to shape and arrange the collection tube 20 in a
sufficiently open contour to permit it to collect water.
The tube 26, upon inflation, stands a substantial distance above
the bottom 12. This shape is maintained until the weight of the
patient distorts or deforms the hair washing aid of the present
invention. To prevent water from accumulating immediately below the
neck of the patient, a levelling tube 32 or pillow is incorporated
on the left and a similar levelling tube 34 is incorporated on the
right. The levelling tubes 32 and 34 are similar so a discussion of
one will suffice for the other. The levelling tubes 32 and 34
extend only a short portion of the circumference of the circular
bottom 12. As shown in FIG. 1, they preferably inscribe an arc of
about 90.degree.. They both incorporate a hollow inflation hose 40
which is sealed off or closed by a similar clamp 42. They can be
partly or fully inflated, dependent on the weight of the head being
washed. When inflated, they elevate the bottom so the bottom is
maintained more or less level. Wash water is not accumulated
immediately below the head of the user, but the bottom is
maintained sufficiently level to drain the water off the bottom and
into the conduit.
The device of the present invention is preferably formed of a
common plastic materials, and for convenience, it is formed of the
same gauge or stock of material. This defines an apparatus which
can be used repeatedly. A person who has been institutionalized for
a substantial period of time in a bed-ridden condition can be
provided by one of these devices for repeated use. When nursing
assistance is provided, the device can be removed from storage and
inflated. Inflation is readily accomplished by inflating the
encircling tube 26 and one of the two head levelling tubes 32 and
34. It is ordinarily not necessary to inflate both of them.
Inflation is accomplished quickly and the device is then positioned
beneath the head of a patient. The patient's hair is captured on
the bottom 12, even very long hair. With this arrangement, nursing
help can provide a complete hair washing to a patient. Wash water
and all rinse water subsequently applied can then be drained
through the conduit wich hangs over the side of a bed. The conduit
may be positioned to the right or left of the bed, at a convenient
place. The conduit can be closed by a clamp which pinches the
conduit shut. It can be readily positioned above a bucket and
drained periodically into the bucket. In the alternative, it can be
positioned above a floor drain and be permitted to spill into the
floor drain from time to time. If desired, it need not be pinched
off, but can drain continuously.
The apparatus of the present invention is particularly useful in
situations other than washing a bed-ridden patient's hair. One use
is in the cleaning of head or scalp lacerations to remove foreign
debris and dried blood from the head and hair. The apparatus
further finds use in the treatment of an extremity other than the
head. Hand or foot injuries can be treated by placing the extremity
on the aid 10 for cleaning prior to treatment. The device can be
used for washing and cleansing burns. It can also be used for
washing and cleansing burns. It can also be used for treatment of
acute burns of the head or extremities. Such treatment has
heretofore been difficult to execute because of the quantities of
liquids which are involved. The device can be used in the
administration of a perineal douche or similar treatment.
The foregoing is directed to the preferred embodiment of the
present invention, the scope of which is determined by the claims
appended hereto.
